Re: [CentOS] Help, PHP/Mysql connections are so slow.

[Pro Green European]

Now I've also tried running a MySQL server on the webserver, and setting for 
example phpmyadmin to connect to localhost does not change any kind of 
behaviour. PHP/Mysql connections are still very slow.

Hi.

I've got a new Centos 5.1 x86-64 server that uses PHP to
communicate with MySQL5. On this server, PHP/Mysql connections are dead
slow and unresponsive. It takes sometimes up to a minute to list tables
in phpmyadmin for example.

I've verified on the server that the
issue has to be PHP/Mysql related. If I use a CGI based Mysql admin
tool, communication is fast and there are no delays.

The server is Xeon based and has 4GB of RAM.

SElinux is enabled, and ModSecurity for Apache too. Disabling these two does 
not help.

SElinux allows Apache to network connect.

Some php.ini settings:
===
safe_mode = On
max_execution_time = 60
max_input_time = 60
memory_limit = 128M
open_basedir is active, and there are no conflicts.
disable_functions also contain several functions in order to secure server.
allow_fopen_url is disabled
===

Could there be a bug somewhere that is causing this slowness for PHP/Mysql 
connections.

Feedback and tips for solving this problem will be greatly appreciated :)

/PGE (aka mysteron)

Answer I've recieved and answered:

Q: Sounds like the server is trying to do a reverse DNS lookup and timing
out after a minute plus. Is DNS set up on the server correctly?

A: Yes, DNS is working correctly. I tried with the IP address of the
database server instead of its DNS name, but there is no difference,
PHP/Mysql connections are still dead slow.

running on centos 4 update 5 for oracle apps.

 Shared gfs partiton are mounted on both the node[active-active]

 Whenever i type df -h command it will take some delay to print my shared
gfs partiton,it is happening even if i continiosly typing df -h command.
Shared GFS file system storage is from IBM STORAGE.

Have you tried other protocols? Is it really only http transfers that are slow?

Have you tried pinging 100 times and see if you get dropped packets?

Are there any errors from the netcards showing up in log files?

Yes, you can (of course). My backupserver boots from CF (only kernel

I do not have a howto here but if you search google, you'll probably
find a lot of them.

Re: [CentOS] new install of 5.1 with KVM-over-IP - can'tinstallwith GUI - need assistance

[Alon]

Hi Bill,

Thankfully, our servers are already setup in the noc.
We have a need for a new install once a week.
While I appreciate the help on the automation and the partitioning,. we are 
deviating from the problem I'm reporting:

How to bypass the VGA prob and use the GUI install while using a KVM setup.

Should I escalate this issue to the RedHat bugzilla?
If an older version of CentOS/RH was able to skipp that prob successfully,. 
CentOS 5.x should have that capability, or at least allow to pass a parameter 
of 'novgaprob' or something like that.

Thanks,

  Maybe this one task can be automated. When I was working on RAS for a
  NAS, we had to be able to handle different HD configurations and sizes.
  In the install/recovery image I generated on CD (this was several years
  past), we used sfdisk to automatically partition the HDs. Using a fixed
  "root" partition size, we calculated the rest of the disk as a % of
  available for each desired partition. Worked great.

[lingu]

HI,

 Sorry for repeating same mail ,while composing that mail i mistakenly typed
the send button.I am facing problem with my gfs and below is the  running
setup.

My setup


Two node Cluster[only to create shared gfs file system] with manual fencing
running on centos 4 update 5 for oracle apps.

 Shared gfs partition are mounted on both the node[active-active]

 Whenever i type df -h command it will take some delay to print my shared
gfs partition,it is happening even if i continuously typing df -h command .
Shared GFS file system storage is from IBM STORAGE.I don't know what
parameter to be fine tuned,bcoz  of that may be i feel my  oracle apps is
also very slow.

In syslog i am getting following error continuously in one of the node

less /var/log/messages

Hi.

Yes. Ftp works perfectly, and regular http with cgi/perl connections to the 
same database server works perfectly. Also rendering of standard HTML works as 
it should. It is only when a scripted site uses PHP/Mysql the connection to the 
server takes forever.

> Have you tried pinging 100 times and see if you get dropped

0% packet loss

None.

I am really baffeled with this problem. I have no idea what to do next. Have 
enabled server-status in Apache and when the scripted site is being access the 
cpu load is around 2.5%.

Re: [CentOS] sendmail and spam

[Peter Farrell]

I agree with previous poster RE: Postini, we have clients that use the
service and it's fantastic.

I use Postfix / Amavisd - Clam-AV / SpamAssassin + SARE rulesets (with
DCC, Pyzor, Razor) locally and ater the initial setup it's excellent.

I've also done just Postfix / Amavisd - Clam-AV / SpamAssassin + SARE
and used Greylisting for other clients as well and that's been
unbelievable. Greylisting as a method to reduce spam is the heat!

In both of the above setups are spread across 3 machines in a
multi-tiered architecture. Use your DMZ to pre-filter, with Postgrey,
header checks, body checks, then allow to next hop where you can
spam-check, virus check, then allow to local intranet mail server for
local delivery / IMAP.

But if you want to farm it out - use Postini.

Re: [CentOS] Compact Flash..

[Peter Farrell]

It's easy. Look - you can get an IDE -to- CF adapter for about a fiver.
Get a 4 or 8 GB CF card and install it on IDE 01.

That's your main drive.

Set up your other drives in what ever config is necessary. Solo,
Software RAID, whatever.

Do your install. Either use the partition editor, or boot into Knoppix
and run gparted to format your other drives.
After install - edit that FSTAB to make sure everything is in order.
For example, on one of the other drives you could set a
mount point as '/data'.

Configure MySQL.
*database can be anywhere, NFS share or other FS. It doesn't matter as
long as you configure my.cnf to tell MySQL where to look.
Here is one of my production machine's my.cnf using databases from a
/data partition (which is on a RAID FS).
Although MySQL is installed at /usr/local - the databases are all on /data.
Read you man pages and have a noodle through the MySQL website for
declaring options for my.cnf

Re: [CentOS] Help, PHP/Mysql connections are so slow.

[Peter Farrell]

If it's a table listing check your MySQL settings. How have you set up
my.cnf? What does your slow query log tell you?
Have you logged into your MySQL server from another machine and ran
queries from there? Have you enabled verbose logging for PHP and
Apache? Are you tailing all 3 while you run the query from phpadmin?
One of them will say something interesting.

I think your issue smells like something in how you compiled PHP  or a
setting in php.ini itself.

Put a  test.php in the doc-root and see what it tells you it's using.
(re; mysql & the php version & the location of the php.ini)
I've done installs where I had conflicting libs from both PHP and
MySQL. Also I get stupid locations for php.ini all the time and have
to manaully move that file to the correct location.

[EMAIL PROTECTED] htdocs]# cat test.php



I generally compile everything when I do a similar install - and give
explicit declarations to where the apxs is for PHP as well as the root
mysql libraries. Check that everything is where you think it is.

*from recent installation of vtiger: (for example)

APACHE 2

--prefix=/data/CRM/apache2 --with-mpm=prefork --enable-ssl
--enable-setenvif --enable-proxy --enable-proxy-http --enable-so
--disable-charset-lite --disable-include --disable-env
--disable-status --disable-autoindex --disable-asis
--disable-negotiation --disable-actions --disable-userdir
--disable-alias
make
make install

PHP 5.2.5

--prefix=/data/CRM/php-5.2.5 --with-zlib-dir=/data/CRM/src/rrdbuild/lb
--with-gd --with-png-dir=/data/CRM/src/rrdbuild/lb
--with-freetype-dir=/data/CRM/src/rrdbuild/lb
--with-jpeg-dir=/data/CRM/src/rrdbuild/lb
--with-imap=/data/CRM/src/rrdbuild/lb
--with-mysql=/usr/local/include/mysql
--with-apxs2=/data/CRM/apache2/bin/apxs
make
make test
make install

=

XCACHE (this is the PHP accelerator we're using)

*you'll have to force it to see the non-standard install locations we're using.
===
Make a build directory:
mkdir xcache-build
cd src/xcache-build/
phpize --clean && phpize
env CPPFLAGS="-I/data/CRM/php-5.2.5/include
-I/data/CRM/apache2/include" LDFLAGS="-L/data/CRM/php-5.2.5/lib
-I/data/CRM/apache2/lib" CFLAGS="-O3 -fPIC" ../xcache-1.2.2/configure
--prefix=/data/CRM/ --enable-xcache
make
make install

*You must re-install each time you upgrade or re-compile PHP
make distclean && phpize --clean && phpize
(now continue w/ original instructions)


Locate a php.ini and copy it to /data/CRM/php-5.2.5/lib/php.ini
Append the xcache options to this file:
cd ../xcache-1.2.2
cat xcache.ini >> /etc/php.ini

Edit the php.ini to comply with the vtiger installation notes:

;Your php.ini must configured with the following parameters:

;* safe_mode = Off
;* display_errors = On*this is stupid. Turn it off
after you tweak vtiger to how you like it.
;* file_uploads = On
;* register_globals = Off
;* max_execution_time = 600

;* memory_limit = 32M *is 128 by default - ignore
;* error_reporting = E_WARNING & ~E_NOTICE
;* allow_call_time_reference = On
;* log_errors = Off*again, stupid - ignore
;* short_open_tag= On*again, why the code is a bit

http://www.redhat.com/docs/en-US/Red_Hat_Enterprise_Linux/5.2/html/Release_Notes/x86/ar01s01.html

Network driver r8169 updated to add support for the following devices:

   RTL8169sb/8110sb
   RTL8169sc/8110sc
   RTL8168b/8111b
   RTL8101e
   RTL8100e


I don't know maybe it's not listed but it's compatible, I know that it
works. Same thing with OSX86, it works 

>
Updating the r8169 driver will not solve a driver issue with the RTL8029 
chip.
The RTL8029 is an old NE2000 clone chip (must be atleast 10 years old by 
now). It was common on cheap 10Mbit PCI cards and is supported by the 
ne2k-pci driver for many years (and the plain ne2k driver before PCI 
support was split out).

Maybe if you trust DNS resolution names to make the connection to the

Hi.



Have you tried other protocols? Is it really only http
transfers that are slow?
  

Yes. Ftp works perfectly, and regular http with cgi/perl connections to the 
same database server works perfectly. Also rendering of standard HTML works as 
it should. It is only when a scripted site uses PHP/Mysql the connection to the 
server takes forever.



Have you tried pinging 100 times and see if you get dropped
packets?
  

0% packet loss



Are there any errors from the netcards showing up in log
files?
  

None.

I am really baffeled with this problem. I have no idea what to do next. Have 
enabled server-status in Apache and when the scripted site is being access the 
cpu load is around 2.5%.

 I generally will do one of two things in addition to my normal backups.

1. run a cron that exports the database, then gzip it - I rsync that
off to another machine.
2. I replicate the database to other machines in the same tier.

I agree about the CF failure as well. No biggie. I would copy it's
partition somewhere else once a week for a potential restore of just
such a failure.

Re: [CentOS] Help, PHP/Mysql connections are so slow.

[Pro Green European]

The query log on the database server tells me that there are around 20-30 
seconds between each data request from the webserver to the database server. 
Accessing the same database from another server, Apache/CGI/Mysql or even 
through the mysql command line is fast, and there are no 20-30 sec delays.

Apache & PHP are the default x86-64 rpm packages that comes with CentOS 5.1:

httpd-devel-2.2.3-11.el5_1.centos.3
httpd-2.2.3-11.el5_1.centos.3
httpd-manual-2.2.3-11.el5_1.centos.3
httpd-devel-2.2.3-11.el5_1.centos.3

php-mbstring-5.1.6-15.el5
php-ldap-5.1.6-15.el5
php-cli-5.1.6-15.el5
php-gd-5.1.6-15.el5
php-common-5.1.6-15.el5
php-5.1.6-15.el5
php-pdo-5.1.6-15.el5
php-mysql-5.1.6-15.el5
php-pear-1.4.9-4

The php.ini file is located in the /etc/ folder.

I also have the same identical site accessing the same database on the same 
mysql server, running on a CentOS4 server without any problem. Reason for 
switching server is that I need PHP5 support, and as the CentOS4 based server 
is a production server, I cannot compile PHP5 from source and use that on the 
server. I have It is a mystery ;)

I'm starting to wonder if this is a broken hardware issue...

[CentOS] syslog - python

[David Hláčik]

Hello , i want all my log messages from python to have in /var/log/python

Now they are in /var/log/messages:

Jun  9 12:10:51 sx1 kernel: klogd 1.4.1, log source = /proc/kmsg started.
Jun  9 12:11:01 sx1 python: MM_MEMBERS [it] Nothing to do.
Jun  9 12:11:02 sx1 python: MM_MEMBERS [research] Nothing to do.
Jun  9 12:12:01 sx1 python: MM_MEMBERS [it] Nothing to do.
Jun  9 12:12:01 sx1 python: MM_MEMBERS [research] Nothing to do.

So i have added to the end of the syslog.conf


# Python
python.*/var/log/python

and restarted syslog,

then i have created /var/log/python and for sure addedd u+rw, g +rw,
o+rw permissions

But, nothing, /var/log/python is empty

What am i doing wrong? (Centos 5.1)

Thanks

CF Fails, i can re inject it into a new CF card and away I go.  yes if 
the HD fails ive lost the database, but its a monitoring box, toss a

but as either cant operate without the other you have just doubled your

Yes, I have tried that too, no difference. I've even tried running MySQL with a 
database populated with identical data on localhost (even tried 127.0.0.1), but 
there is no difference in performance. Delays in the connection to the db 
server is still around 20-30 seconds.

So, the problem has to be with either the php-mysql module, PHP itself, MySQL 
or then it may be hardware related.

Re: [CentOS] Help, PHP/Mysql connections are so slow.

[Peter Farrell]

If the database is on a different server.
and the CLI access to mysql is normal.
and other php / apache instances can access the database;

then it has to be either
a problem with apache <--> php communication
or a problem with php <--> mysql communication.

Write  a test query in php and execute at the command line on this
server and see what output you get.

I think the previous poster that recommended the DNS investigation
might have been on to something as well.
That 20-30 seconds could be name failure resolution, etc. Worth
looking at. In your phpadmin are you giving the FQDN or the IP
address?
I've many times forgotten to add a new default route w/ multi-homed machines.
The DNS explanation would make sense as well if nothing (as you say)
is being logged as errors in any of your log files.
The delay could be purely DNS related.

Check your httpd:
ldd /path/to/httpd
for the libs compiled with httpd.

# httpd -l
for the moduled compiled into httpd.

cat your httpd.conf and double check your php5 module is included as well.

Really take a minute as well to check your php options.

# php -i

And double check your PATHS and MYSQL_HOME and MYSQL_BIN.

With linux it's always something bitty like this that can screw you up.

-Peter

What happens if you include a largish file in php? Is that also slow?

Have you tried MySQL without php? Ie a mysql dump'n'reload on the command line?

AFAIK, it is not possible to (re-)export NFS mounted file systems using

It might be possible to do this by running a userland NFS server (on

Re: [CentOS] Help, PHP/Mysql connections are so slow.

[Pro Green European]

Hi.

Yes, I have tried that too, no difference. I've even tried running MySQL with a 
database populated with identical data on localhost (even tried 127.0.0.1), but 
there is no difference in performance. Delays in the connection to the db 
server is still around 20-30 seconds.

So, the problem has to be with either the php-mysql module, PHP itself, MySQL 
or then it may be hardware related.


Thx,
/mysteron

Probably not at all. You would have to redirect .err or .warn for a

You can change facilities for some applications, but I don't know if 
Python allows this.
What you could do, is extract all python stuff from the messages log

How did you move the database? You moved from PHP4 to 5 and from MySQL4 to 
5. You *have* to expect problems.

> I'm starting to wonder if this is a broken hardware issue...

I think what you have not done yet, is test a simple PHP page with a 
simple SQL query to a *different* simple, new database with just a few 
data.

BTW: the mysqladmin list of connections can show the current connection 
status of queries, the statement etc. and thus help in debugging. The same 
list can be obtained from within PHPMyadmin.

We will have a newer version of Network Manager and wpa_supplicant in

With this configuration it works correct with Sidux (a debian clone).

[CentOS] TFP inside firewall

Hi,

I have a setup where the tftp server is inside the firewall.

Now the issue is tftp client send request on dynamic udp port. Can anyone
give some idea, how i can bind the fixed port for client udp requests ?
Otherwise i hope, it is not a solution that i will open all port related to

Re: [CentOS] Slow gfs performance

[James Thompson]

You don't mention it but I assume you are running on Fiber Channel not iSCSI? I 
am running GFS using CentOS 5.1 from two servers using iSCSI. I have Device 
Mapper Multipath setup so that makes my performance characteristics a little 
different but I have tuned the servers with the following commands:

gfs_tool settune  demotes_secs 600
gfs_tool settune  scand_secs 10
gfs_tool settune  statfs_slots 128

The first two I have set until 5.2 drops which will contain an additional GFS 
tuning parameter, glock_purge. Update 5 of CentOS 4 may already have the 
glock_purge parameter available. Run the command 'gfs_tool gettune 
' and see if glock_purge is listed. It should be set to zero by 
default.

If it is there you can refer to this brief write up on tuning with glock_purge 
since you will not want to use the demote_secs and scand_secs settings I am 
using: 
http://open-sharedroot.org/Members/marc/blog/blog-on-gfs/glock-trimming-patch/?searchterm=glocks

Also, as a further note, your particular usage scenario will dictate what 
tunings are appropriate. I am not familiar with Oracle's usage of I/O but will 
both servers be accessing the same data on disk (particularly with regards to 
writing) at the same time?

Doesn't help you now, but rsyslog has the ability to filter by regular
expression in addition to the usual log facilities, and rsyslog will
be in 5.2 when it gets released. So if you can wait until 5.2 comes
out, you'll be able to filter the way you want.

If the UPS is not equipted with a network management card, then you can only 
connect the UPS to one server.
This does not mean that you can manage only one server! The UPS software let 
you run custom scripts on (shutdown) events.

Create ssh key-pair on second server, and create a rs(s)h script to logon 
with the just created ssh keys to the second server where it runs a 
(shutdown) script. This can also be done for the third fourth and so on. You 
of course run different scripts on different events

Not to disparage syslog-ng, but you may want to check out rsyslog.
It'll very likely be the default in centos6, and is currently the
default in fedora. You can check the fedora reasoning here ->

And weird ones, to that. If I try to remove Gnome Desktop Environment this 
results in a second dependency check that then wants to remove many 
libraries that KDE relies on and then to remove KDE as well. So, if one 
wants to get *really* rid of Gnome one should indeed first uninstall

As a sneak preview I can already tell you that CentOS 5.2 already will
have rsyslog instead of the old plain syslog.

Why not? Firewalling/routing is not a problem just use fixed ports on

AFAIK, you can NOT re-export nfs mounts, it's not working and it's not

It sounds like the MySQL server is configured to do reverse DNS lookups
on incoming connections, and those DNS lookups are timing out.  For
small systems (a few web servers and a db server) I tend to add the web
servers to the system's hosts file, so the mysql server doesn't have to
do a DNS lookup for every connection.

Have you checked that the nameservers in resolv.conf on the MySQL server
are reachable?

"rssh" rssh is a restricted shell for use with OpenSSH, allowing only 
scp and/or sftp. For example, if you have a server which you only want

access, you can use rssh to do that.

Hi,

Is anyone chrooting users that connect through SSH?

I looked for it on Google and I basically saw several methods:
- OpenSSH 5 supports ChrootDirectory (FC9 apparently has RPMs that
probably could be rebuilt under CentOS 5)
- There seem to be several patches for OpenSSH 4.x to do the chroot,
the most popular seems to be http://chrootssh.sf.net/
- There appears to be a pam_chroot
- There are solutions based on setting the user's shell to a
script/binary that does the chroot

By quickly looking at yum list, it doesn't seem like neither RHEL nor
CentOS directly support any of those, at least I didn't find any RPMs
for any of those.

If anyone is doing it, I would like to know what were your experiences
and if you would recommend doing it or not.

I'm specially interested in anything that doesn't involve replacing
the OpenSSH that comes with CentOS, after all, that's what CentOS is
all about, if you start replacing the pieces, what's the point...

We're not setup for ESMTP as it's a closed network and I'm really

In case it helps, my sendmail.cf file is below.

I should add that sendmail is definitely running :).  I can telnet to 
the box on port 25 and get a reply, and  "service sendmail status" 
returns 'running' with at least one pid.

Re: [CentOS] sendmail not sending after reboot

HI,


  Check the below things on your server.


1) diskspace

2) mailq

3) netstat -ntlp |grep :25 |grep tcp

4) telnet on  port 25 from server as well as from client

5) ps auxxww |grep sendmail

you should get output like below###

Queue [EMAIL PROTECTED]:00:00 for /var/spool/clientmqueue


5) check maillog properly definitely it will throw some  messages

6) check /var/log/messages .



  Check  the maillog otherwise increase the sendmail loglevel in the
sendmail.mc file to 10 and restart sendmail.





Line to be changed in sendmail.mc to increase log level.

Re: [CentOS] OT: really dumb question about APC UPS

[Peter Farrell]

Agreed:

"If you use the apcupsd software you can create a network (UPS) server
and clients which will automatically shutdown on a signal from the
server. But make sure you connect your network switch to the ups as
well ;) You then only have to connect 1 machine to the ups which will
act as a server for the other three."

You want to use the apcupsd package. Connect the one machine via
serial port / usb to the UPS.
That's your new APC server - running a master apcupd daemon.

Now set up the same daemon on the other host and they will communicate
to the APC master host to get the status of the APC unit itself. At a
user defined threshold, like '10% battery left' you can configure
shutdown events. You can space these out so you bring down your
superfluous machines (dev env) then the webservers, the app servers
and the database servers, with your intranet samba / apache as last on
the list for example. You can configure it to cascade all the machines
how ever you like.

http://www.apcupsd.org/

For example a host:

I think we just found another argument as to why top-posting is a bad

Re: [CentOS] Help, PHP/Mysql connections are so slow.

[Pro Green European]

Thank you for all your time and replies :)

I solved the problem by switching to RHEL 5.2 x86_64 on the same server. Now 
PHP/Mysql is working properly.

Strange thing though, every setting is identical to that of the CentOS 5.1 
x86_64 install.

I recall reading something about there being a bug with InnoDB and
causing 20-30 second queries with mysql 5.0.22. The solution, I think,
was to upgrade to at least MySQL 5.0.30.

What version is RHEL 5.2 running?

I believe this is the bug:

[CentOS] iptables starting while disabled

[Joseph L. Casale]

I have a xen machine that has iptables turned off, and after a reboot it 
started behaving
badly during times when network IO rose to anything other than almost nil. 
Since I know
iptables makes xen unstable without some additional config and since its 
isolated I just
have is disabled. As a result it was the last place I looked and spent the 
better half of the
day chasing my tail.

Somehow it gets turned on after a reboot, how can I deduce what is activating 
it?

Thanks!

ISSUE RESOLVED:

Thanks for jpegNY  (CentOS forums) the issue has been resolved:

Upon boot, the parameter to pass is:

As stated by Karanbir your processor requires rpms that end in
ia64.rpm not i686.rpm or i386.rpm or x86_64.rpm though noarch.rpm is
acceptable.

Re: [CentOS] iptables starting while disabled

[Peter Farrell]

I'm not sure as it relates specifically to XEN - but I would have a
look through the /etc/rc.d
directory. If it's not being turned on there, 'egrep -i iptables'
/etc/init.d/* and see if it's in any startup script there.
Slim chance they may be something in rc.local as well.

perhaps this may be of help if you adapt it to your
situation.==
This
is a brief description of how to set up the 4.6 kernel so that
it will boot on list.The
reason that the stock CentOS 4.6 kernel will not boot on list is
that LSI and Dell madethe
decision to remove support for the PERC/LSI controller adapter
shipped with the PowerEdge2600
from the 4.6 kernel. The new megaraid subsystem supports the
PERC/LSIcontrollers shipped with
the newer PowerEdge 2900 models. The stock 4.5 and 4.6
kernelswill not boot on an older
2600.The 4.4 kernel is called 2.6.9-42.EL or 2.6.9-42.ELsmp in
the symmetric
multiprocessor version.The 4.6 kernel that first shipped is
called 2.6.9-67. The current
topof tree is 2.6.9-67.0.15 as of May 13 2008). When we compare
the megaraid_sas.cdrivers
(for example), we see that a lot of generic support has been
taken out of the newerversion,
compared with the driver from 4.4 (2.6.9-42.EL).For a full scan
of the differences
between all source files in the megaraid directory,
seenewdifftxt in this directory.So what we have to do is take
out a top of tree 4.6 kernel, wipe out all the code in
themegaraid directory, put back all the old megaraid code, then
build a kernel. To get theold
source kernel, use www.rpmfind.org to search for the proper
kernel:kernel-2.6.9-42.EL.src.rpm.
The current top of tree source magically appears
in/usr/src/redhat/BUILD/kernel-2.6.9/linux-2.6.9 when we
performyum install kernel* and follow
the instructions to build a custom kernel.This is not trivial,
but all the instructions are
athttp://wiki.centos.org/HowTos/Custom_KernelThe basic steps I
took were slightly
different:---1)
Download the stock 4.4 kernel
source using rpmfind2) Build the stock 4.4 kernel, install, and
test boot it to validate the
process.3) Save off the megaraid directory code which is
probably
in/usr/src/redhat/BUILD/kernel-2.6.9/linux-2.6.9/drivers/scsi/megaraid4.
Change the name of the
prior kernel to something like/usr/src/redhat/BUILD.old, etcSo

AFAIS iptables is active all the time in CentOS 5. Deactivating the service 
just 
means that queues are empty. Starting libvirtd and creating xen machines 
definitely 
adds to the queues.

Use find with either -exec or with xargs, and pass it either a -ctime
or -mtime option for what you need.

for example, find /path/ -type f -mtime -2 -name '*.txt'  -exec cp {}
/path/to/copy/to/

this may not be 100% syntactically correct, but should give you the
general idea.

to copy all files in /dir1 modified within the last 5 days to /dir2:

$ find /dir1 -mtime -5 | xargs -I {} cp {} /dir2

if the filenames have whitespace in them, you can use this trick:

$ find /dir1 -mtime -5 -print0 | xargs -0 -I {} cp {} /dir2

for more details on selecting by time:

$ man find

pay particular attention to the options -atime, -amin, -ctime, -cmin,

Hi Kai,

Thanks for your reply.  Yes, that one was a connection to itself...but 
the msg remains when connecting from a client.  My last post must have 
crossed with yours.
It now appears to be nothing more than a server timeout issue which is 
very strange as this server's load averages are /always/ < .10. 

I'm not sure what might have changed since the reboot on Sunday 
morningam now looking at what is or is not running against the 
snapshot taken on Friday night.
Do you think it's wise to replace the sendmail.cf and sendmail.mc files 
from the snapshot (after backing them up, of course)?

Actually I need to copy this on to another server with same folder structure. I 
think I need to explain bit of history.

I had a server crash last week, and we have restored the files from the tape. 
However during this period of making the server up, the users having adding or 
changed files from our backup Server (Samba server which rsync to production 
server every night.) now I need to copy the files which user added/ modify last 
7 days. Ideally if I can get this option in rsync it would be better. Otherwise 
I need to have a method so that all changed files to go on the relevant folder 
on the production server. I cannot take the full files in the backup files 
since they are historical backup and there are some unwanted files. 

Can I use scp instead of cp in your statement?. But how does it take the same 
directory name as the original location?

Eg:from ServerA/FLDR2/FLDR3/Filename should go to ServerB/FLDR2/FLDR3/FILENAME

Only change is the server name all other values will remain same.

Any help would be really appreciated.

Thanks

Rajeev

[CentOS] Re: new install of 5.1 with KVM-over-IP - can't install with GUI - need assistance

[Scott Silva]

on 6-7-2008 8:06 AM Alon spake the following:

Hi All,
 
I have several dozens of CentOS and WhiteBox servers.

Most of them are CentOS 4.6.
Our installation service is done in the datacenter where the servers are 
located.
 
When we install a fresh clean install, we use the GUI menus, while using 
the KVMoverIP.
 
That was working great with CentOS 4.x
 
In CentOS 5.x, the installation process 'annonces" that "Hey,. I know 
you are using a KVM and don't have a monitor attached"   (who cares??).
But, "since  you are using a KVM and no monitor is attached,. you CANNOT 
use the GUI installation".
 
Why???
 
4.x didn't care for this.
 
Why make my life difficult?
 
I have to 'cheat' by calling the datacenter to plug a monitor for the 
first minute of the install and then plug back the KVM cable.

Isn't this stupid? of course it is!
 
I am looking for a solution such as a parameter that I can pass to the 
boot sequence (vga=nommconf or something like that) so that it won't do 
the probing for the VGA and just let me go about my business.
 
 
Mind you that this is a problem both with DELL PowerEdge 1950iii with 
DRAC5 remote consule as well as with just plain PCs that use ATEN KVM 9116.
Once the probe understand that we don't use a monitor it prompts the 
'can't use the GUI'.
 
Any pointers about this?
 
 
Thanks,
 
-Sup.
I believe there is a "headless" parameter you can use. I have used it for VNC 
installs. It might work for you.

[CentOS] Re: Software raid tutorial and hardware raid questions.

[Scott Silva]

on 6-7-2008 9:35 AM drew einhorn spake the following:

I remember seeing one with an example migrating
from an old fashioned filesystem on a partition
to a new filesystem on a mirrored lvm logical volume
but one only one side of the mirror is set up at this
time. 


First I need to copy stuff from what will become
the second side of the mirror
to filesystem on the first side or the mirror

Then I will be ready to follow the rest of the tutorial
and build and attach the second side of the mirror.

Wish I could remember where I saw that tutorial.

Want to embellish the example and stripe each side
of the mirror.

Understanding  a mirrored pair of stripes,
seems easier than
understanding a striped pair of mirrors.

But this seems like a place where
counterintuitive results are not a big surprise.

I can do mirroring and striping in lvm, mdadm,
or a hardware raid controller.  There are lots of
configurations to ponder.

What about recovery after a hardware raid controller?

What are the chances of being able to replace the controller
and start up successfully from drives?  I know that assuming
the failed controller did write bad stuff to the drives while
it was crashing and burning.

I would not be surprised if the controller firmware revisions
had to match.  I would be surprised but not astonished if
the board hardware revision level had to match, too.
I hope we are past those days.

Anybody know about the
LSI Logic MegaRAID 8480 Storage controller
in particular.

I know that with 3ware controllers, they are always backward compatible, and 
will sell you a controller that will work. As to the "bad" activity, nothing 
will mitigate backups.

Re: [CentOS] sendmail not sending after reboot UPDATE

[Ray Leventhal]

where does the server point to for its dns? if it's (supposed to be)
running a nameserver (e.g., you're pointing to 127.0.0.1) but the dns
server isn't running you'll get a timeout. if you have a second
nameserver configured in /etc/resolv.conf you'll likely ultimately
get a response, but only after you time out on the first.

by the way, you may want to look at the server's "client" sendmail
queue ("mailq -Ac"). the remote clients dump to the regular queue
(/var/spool/mqueue), but localhost mail goes into the clientmqueue
(/var/spool/clientmqueue). if mail is hanging there it might give
hints that are easier to debug than are remote connections. [you may
also want to try originating mail from localhost and see what
happens.]

The server points to another server on the network for dns, which is 
running and accepting queries on 53, as expected.  resolv.conf points to 
the correct nameserver IP.


I'll check the client queue..hadn't thought of that.
Thanks,

[CentOS] Re: Compact Flash..

on 6-9-2008 3:40 AM Peter Farrell spake the following:

 I generally will do one of two things in addition to my normal backups.

1. run a cron that exports the database, then gzip it - I rsync that
off to another machine.
2. I replicate the database to other machines in the same tier.

I agree about the CF failure as well. No biggie. I would copy it's
partition somewhere else once a week for a potential restore of just
such a failure.

-Peter
I could see the CF as a faster boot, but it might just be easier to software 
raid 2 drives and not worry about the mix. One drive fails, you swap and 
resync, 2 drives fail, well you did say something about backups!  ;-P

If you did not change the files: no. As I said: go thru a manual send and 
check *where* the timeout occurs (better: repeat it a few times to be sure 
it's always in the same phase). The messages in the logs are not very 
clear about this. If your users have to authenticate before sending this 
could be a typical point-of-failure where after the reboot the 
authentication against an external mechanism is somehow hampered. I guess, 
you do have any spam protection on the machine as you said it's not taking 
external mail?

DNS.  It's always DNS :-)

(more accurately, host and IP address resolution).

How long is it taking your server to resolve the IP address into a
name?  To resolve names into IP addresses?  To resolve destination MX

HI folks,

I've an up-to-date CentOS 5.x box on a small intranet (<20 users).

Yes, backups are absolutely neccessary,  but one hopes that in many cases a
quicker, easier, recovery is possible.  It is desirable that the filesystems
will come up with old drives and a new controller.  But sometimes that is
just not possible if a failing controller wrote bad stuff on the drives.

One approach would be to use the find command given above to generate a
list of files that have changed.  Then pass that list to rsync via the
'--files-from' option to transfer them to the other server.

[CentOS] netboot, vnc and no keyboard/mouse/monitor

[dnk]

hey guys,

I just created a custom netboot cd, that launches and loads from a  
http source, but connects to a vnc listening viewer. All in all, not  
hard to do, but what is different with this one is that it skips the  
media check, has no prompts and allows you to start the install on a  
machine that has no keyboard/mouse/monitor. Was handy for me as when i  
have some boxes to load, I just plug in power and ethernet in the  
corner (or where ever I have room) and go through the install.


I know it also works with a cd as a source (if you use it from cd 1),  
and assume it would also work with a DVD (have not tested yet).


If you would like it, I can add to the wiki if anyone would like it.

nothing but vanilla stuff here, for email.  no milters, no spam

I will do as you suggested;  I'll telnet from a client-host and do the

At a minimum you need "DAEMON_OPTIONS(`Port=smtp,Addr=127.0.0.1,

Hi Stephen,

While I agree, I'm still a bit stumped.  Nothing changed other than a

What you posted was the sendmail.mc file. That might not be the options your 
system was running on if you never actually ran it through the macro 
processor. As I was looking through the rest of the thread, it looks as if you 
are not running on the settings in the sendmail.mc file. Do you run webmin on 
this server, as it will allow you to make changes directly in your sendmail.cf 
file.

like it on the wiki. Due to the way the disk needs to be built, We  
can't just have an iso for download due to the fact that you have to
