Re: rescue Inno tables from an abandoned data directory?

The data directory consists of a mix of ISAM and Inno tables. I was able to copy the ISAM tables into a new 5.6 version, and they work. Assuming you mean 5.5.22 or 5.6.22, then sometimes you can recover a table without partitions with its own .ibd file (file-per-table) using the transportable tablespace features: 1. Install a fresh copy of 5.6 2. Create the table (using a normal CREATE TABLE statement). If you don't know the table definition use mysqlfrm from MySQL Utilities (https://dev.mysql.com/doc/mysql-utilities/1.6/en/mysqlfrm.html) 3. Discard the tablespace (ALTER TABLE DISCARD TABLESPACE) 4. Copy the .ibd file (make sure you work with a copy) into the new 5.6 instance (e.g. for the table db1.t1 copy to /db1/t1.ibd) 5. Import the tablespace (ALTER TABLE IMPORT TABLESPACE) There is also an example in https://dev.mysql.com/doc/refman/5.7/en/innodb-transportable-tablespace-examples.html The import in step 5. will complain that there is no .cfg file from a proper tablespace copy, but InnoDB will do a best effort to import it, and I don't think I've seen it fail if the tablespace has been valid.

The data directory consists of a mix of ISAM and Inno tables. I was able to copy the ISAM tables into a new 5.6 version, and they work. I understand that INNO tables are different because different tables share a common table space. The MySQL documentation refers to a “cold backup,” where you copy the separate files after a “slow shutdown.” It doesn’t tell you what to do with them after you’ve put them in a “safe place.” The recommendation here is that if your DB is in an inconsistent state, the last thing you want to do is break it even further. The flat OS files copy of the DD simply gives us a fallback should our recover operations on the DD make matters worse, eg via innodb_force_recovery etc In my case, I can reproduce Time machine backups of data directories at varying times. At one point I was able to replace the non-working installation with an earlier installation, but then it failed unpredictably. The steps you took and an associated error log would assist me in assisting you. Also accurate information on the version helps, 5.5.22? 5.1.22 ? as mentioned there is no 5.22. In general this approach can be taken; If the DB successfully started , then your first port of call is to perform this action again with the same DD snapshot and attempt a logical dump of any tables you wish to recover. Without knowing what state the db is in , I would recommend starting with [mysqld] innodb_force_recovery = 1 read_only skip_slave_start https://dev.mysql.com/doc/refman/5.5/en/forcing-innodb-recovery.html https://dev.mysql.com/doc/refman/5.5/en/server-system-variables.html#sysvar_read_only https://dev.mysql.com/doc/refman/5.5/en/replication-options-slave.html#option_mysqld_skip-slave-start and seeing if you can access / dump the tables in question. If not , iterate through 2,3,4,5,6 ( in order! ) to see if that assists. If this doesn't work, try the latest version of the current tree you are on. ie if 5.5 https://dev.mysql.com/doc/relnotes/mysql/5.5/en/news-5-5-53.html failing that, hail mary it with latest 5.7, you may get lucky with TT https://dev.mysql.com/doc/refman/5.7/en/glossary.html#glos_transportable_tablespace GL Are the Inno tables on Time Machine useless, or can I rescue data from them?

Hi, you can check your file limits with $ ulimit -Hn $ ulimit -Sn The limits are configured in /etc/security/limits.conf If you google for it, you will find, how to set. After changing, new opend shells will have the new parameters. After changing them, your first error message " Changed limits: max_open_files: 1024 (requested 5000)" should be gone, maybe the next one too.

RE: *.index files in MySQL Data directory
There are files beginning with 1.. The sequence number is 01 to 15. A new file is created every time MySQL is restarted. The 1.index file contains a list of these files. One thing that I have done is when I was hardening the security we stopped MySQL and moved the data directory to a directory called /var/lib/db/mysql.

Maybe you do not use innodb tables, in that case there would be no data loss. On Thursday, August 27, 2009, Jia Chen wrote: > Thanks for the tips.

Thanks for the tips. Where can I find more details about the ibdata file? After I changed the data dir, hese file did get recreated. So far, I have not noticed any data loss yet.

Re: Fail to change MySQL data directory on ubuntu
That procedure is horribly incorrect. You should simply move the ib_log and ibdata files with the rest of the datadir.

Hi Johnny,
Thanks you so much!
Your command fixed the problem beautifully. Now, MySQL can start
successfully. I can create and drop databases without problem. Thanks again.
Best,
Jia

Re: Fail to change MySQL data directory on ubuntu

Re: Data directory in 2 platforms
On a dual boot it should work okay. I've done a similar thing, by taking the data folder from a Linux installation, copying it to a local windows computer and using a local install (same version of course) to read it. It worked fine. I would think the scenario is much the same as what you're suggesting. Any issues with the file system in Linux would be the same in windows as well (filename length, etc..) so if it's working in windows, it should work fine in Linux too. However, before committing, try it out with backed up data of course! -Micah On 12/24/2007 01:15 PM, Ahmad AlTwaijiry wrote: Good morning everyone, If I want to run MySQL server in Windows and Linux OS (dual boot desktop), but I want to make the data directory (the one that has all the databases tables and information) in one shared VFAT filesystem so if I create a database while I'm running in Linux and then reboot to windows and start mysql server I can see the database with all the tables from windows my concerns are: 1. is it possible to share the data directory in more than one OS ? 2.

protecting sensitive info in data directory
i am working on a data collection system for an epidemiological study.
the study holds among other things sensitive personal information. the
personal info is stored in ONE table (i am using innodb_file_per_table)
which we encrypt and wipe after the server is shutdown.
the question is, where else could this data sit on disk? since i am new
to MySQL, i am trying to get clear on the log files, what they contain,
which ones hold data. i gather if we want to be able to perform
rollbacks, we would need to keep the log files around, and since they
store SQL transactions, we would have to encrypt (and wipe) them as
well after the data collection session is over and server is shut down.
right now i see ib_logfile{0,1}files and an ibdata1 file in addition to
our *.frm and *.ibd tables. need we encrypt the *.frm files as well?
which of the ibXXX files need we encrypt? are there any other MySQL
files ANYWHERE that i should be aware of? Does MySQL ever write anything
to the Windows temp directories? (Windows only app)
yes, i am aware of MySQL encryption on a per field basis. we were asked
to encrypt the whole table.
many thanks

But upgrading MySQL like installing it
after MySQL's guide brings a problem: I'd need to move the data

That is what I do. I find it easier than moving the data directory to

I wrapped it all in a shellscript to be run by root.
Assuming mysql is installed in /usr/local like this:
lrwxr-xr-x 1 root wheel 37 May 2 14:34 mysql ->
mysql-standard-5.0.20a-osx10.4-powerpc
drwxr-xr-x 19 root mysql 646 May 2 14:34 mysql-standard-5.0.20a-osx10.4-powerpc
And I have a tar.gz 'mysql-standard-5.0.21-osx10.4-powerpc.tar.gz',
and the script below is called 'update-mysql.sh', this:
# update-mysql.sh mysql-standard-5.0.21-osx10.4-powerpc.tar.gz
Updates mysql to version 5.0.21. All I have to do manually is remove
the directory with the old version. I'm sure I could automate that
also but I thought it was good enough like this.

RE: How to move the MySQL data directory?
Apologies, I didn't read your initial posting properly. Perhaps a glance
at this http://dev.mysql.com/doc/refman/5.0/en/mysqld-multi.html would
provide you the facilities that you require for using multiple servers.
This work well and enables you to manage the multiple global
configuration files required.

Hi Yves,
You could also have changed the directory in the global /etc/my.cnf file
by setting
datadir=/path/to/mysql/data
This is pretty simple and works a lot easier than hacking the init
scripts.

Okay, since hacking seems to be required anyway, I hacked it the
straight-forward and least-change way. I already had datadir=... changed
in the init script to the correct location. Now I also insert some
variables corrections in bin/mysqld_safe:
# here are the lines where ledir is set totally wrong...
MY_BASEDIR_VERSION=`pwd`
ledir=${MY_BASEDIR_VERSION}/bin
DATADIR=`pwd | sed -r "s;/usr/local/;/var/;"`/data
defaults="--defaults-file=${DATADIR}/my.cnf"
# user=... and so on
This does the job pretty well for MySQL 4.0. Need to do it with every
upgrade, but I think I can automate it.
MySQL 5.0 required a less invasive hack though. I saw that setting
datadir= in the proposed init script is for nothing at the very
beginning since it's overwritten again right below. So moving that line
further down helped. Then the mysqld_safe call in the 'start' section
required an additional parameter --defaults-file=$datadir/my.cnf to make
it read my socket name, IP & port etc.
Now both servers are up and running fine again, side by side, with the
*entire* data directory moved somewhere else, saving me from handling
that with every upgrade. Thanks for your help, I thought it could be
done an easy way but it seems nobody has thought about doing that
before. At least I don't have the impression, from reading the scripts.

Okay, since hacking seems to be required anyway, I hacked it the
straight-forward and least-change way. I already had datadir=... changed
in the init script to the correct location. Now I also insert some
variables corrections in bin/mysqld_safe:
# here are the lines where ledir is set totally wrong...
MY_BASEDIR_VERSION=`pwd`
ledir=${MY_BASEDIR_VERSION}/bin
DATADIR=`pwd | sed -r "s;/usr/local/;/var/;"`/data
defaults="--defaults-file=${DATADIR}/my.cnf"
# user=... and so on
This does the job pretty well for MySQL 4.0. Need to do it with every
upgrade, but I think I can automate it.
MySQL 5.0 required a less invasive hack though. I saw that setting
datadir= in the proposed init script is for nothing at the very
beginning since it's overwritten again right below. So moving that line
further down helped. Then the mysqld_safe call in the 'start' section
required an additional parameter --defaults-file=$datadir/my.cnf to make
it read my socket name, IP & port etc.
Now both servers are up and running fine again, side by side, with the
*entire* data directory moved somewhere else, saving me from handling
that with every upgrade. Thanks for your help, I thought it could be
done an easy way but it seems nobody has thought about doing that
before. At least I don't have the impression, from reading the scripts.

Re: How to move the MySQL data directory?
Well, moving the datadir to the new MySQL 5.0.21 directory, messing around with all the stupid symlinks, it seems I have finally managed to delete that datadir... It was empty anyway, yet, but this is an extremely dangerous task. So I really need to move the datadir to a safe place, outside all that symlinked chaos. With that done, what is the proposed upgrade method anyway? 1. unpack the tarball to /usr/local/mysql-$version 2. chown root:mysql it all (what for, actually?) 3. stop the server 4. update the symlink /usr/local/mysql5 to the new directory 5. start the server Would that be okay? -- Yves Goergen "LonelyPixel" <[EMAIL PROTECTED]> http://beta.unclassified.de – My web laboratory. -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]
How to move the MySQL data directory?
Hello, I've just wanted to update MySQL 5.0 on my test machine that will be a productive server very soon. But upgrading MySQL like installing it after MySQL's guide brings a problem: I'd need to move the data directory to the new programme directory every time. So I want to move the datadir outside the application's directory, from /usr/local/mysql5/data (with mysql5 being a symlink to mysql-5.0.xx-...) to /var/mysql5/data. So I moved the entire data directory to the new location and tried to start the MySQL server. After a while printing out dots, it says "ERROR!" and that's it. When I have tried it with MySQL 4.0 and after adding some more of the suppressed output to the scripts, it seems like the startup script expects at least the "mysql" database to be located inside $basedir/data/mysql which of course is not what I meant to do. Is this true that MySQL wants all its databases to be inside the programme directory? Is there any other way to move the datadir out there without hacking all the scripts - over and over with each update? (Then I could just as well move the datadir each time...) -- Yves Goergen "LonelyPixel" <[EMAIL PROTECTED]> http://beta.unclassified.de – My web laboratory. -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]

RE: Newbie Query: Error starting MySQL..changed Data Directory
>>Running /etc/rc.d/init.d/mysqld start says that mysql start failed BUT This doesn't nesessarily mean that mysql hasn't started. This script waits only for certain time to check if mysql has started or not. If it is not started in that time, it simply says 'mysql start failed'. But mysql may take some more time to come up. So the best practice is to have a look at the logs (as you rightly did) to find out what exactly is going on. And your logs anyway are saying "/usr/libexec/mysqld: ready for connections.". This means that mysql has started without any problems and waiting for connections. >>ps -aux shows that mysql is running And for the same reason I mentioned above, you are seeing this.

Problem starting MySQL With Moved Data Directory
I'm using MySQL 4.0.24-10 on Debian Sarge (Linux, and the stable branch of Debian, just to clarify). I had a setup of a program I've been working on for several years that is on a RAID. I changed MySQL's data directory so it will be on the same RAID and backed up, along with all my other data and programs. Originally this was set up under a Debian-based distro that was based on the testing and unstable branches of Debian. Before putting the server into production, I wanted to change it to Debian Stable (Sarge) for safety. (I'll sleep easier at night if it's on Sarge with regular security updates than depending on unstable packages!) So I backed up all the data on the RAID, wiped the original boot/system drive, installed Debian Sarge, did an fsck on the RAID, found errors, wiped it out, restored the original data, including the MySQL db files. When I installed MySQL on the re-done system, it worked. When altered the line in /etc/mysql/my.cnf from: datadir = /var/lib/mysql to: datadir = /thresh/tNet/db and restarted MySQL with /etc/init.d/mysql start, I get the following: Starting MySQL database server: mysqld. Checking for crashed MySQL tables in the background. /usr/bin/mysqladmin: connect to server at 'localhost' failed error: 'Access denied for user: '[EMAIL PROTECTED]' (Using password: YES)' /usr/bin/mysqladmin: connect to server at 'localhost' failed error: 'Access denied for user: '[EMAIL PROTECTED]' (Using password: YES)' However, after I got this, I entered "mysql" and got a connection. The databases and tables seemed intact. I checked, and it turned out that somewhere in the backup/restore process the ownership of the files was changed. I went through and changed the ownership of /thresh/tNet/db to mysql:mysql and changed the ownership of /thresh/tNet/db/mysql to mysql:root. Basically, I changed the ownership of the files in the new data directory to match what I found in /var/lib/mysql, then I stopped and restarted MySQL. I still got the same error messages. While MySQL is working, I don't want to do anything with it because I'm not clear why debian-sys-maint needs access, as opposed to just the user mysql. To test, I made sure all the files from the db directory on down were set for all to read and write and all directories set for all to read, write, and execute. That doesn't help. So what is wrong, what do I need to do, and why didn't I get this error when using the same database directory before? Thanks for any help!

Read Only Data Directory
Hey yall, I'm trying to use a DVD (containing a number of packed MyISAM tables in a directory) as the datadir in my my.cnf but I can't start the server: mysqld is trying to write to the datadir - error log, etc - and when it can't the server craters. Is there anyway of using a readonly directory as the datadir? Are there other options I can specify in my.cnf where I can tell mysqld to write the error files/etc? TIA, Jake

Just an FYI, but you can also specify at startup of mysqld by passing the "--datadir" option.

RE: how to change default data directory
Hi Sanjay, I see two ways to proceed : 1 - after install, move or copy (with -R option) your actual datadir under /var/lib/mysql (that is to say all the directories located under /var/lib/mysql/*) to /var1/lib/mysql, and then modify in your my.cnf the variable to correspond with the new directory. NOTE : stop the mysqld daemon before copying or moving directories. 2 - before install, configure in your my.cnf the futur directory to use with the variable ; then place it under /etc/ - this cause the script to find in /etc/my.cnf the datadir to use. After install, you'll see that the directories mysql and test are placed under Hope this help Thierno6C -Original Message- From: sanjay gupta [mailto:[EMAIL PROTECTED] Sent: jeudi 4 septembre 2003 09:35 To: [EMAIL PROTECTED] Subject: how to change default data directory Hi All , I am using RH7.1 box .

Re: NAS vs SAN for data directory
Avoid NAS... that's like dealing with mysql via NFS ... Internal raid depending on controller type and disk configuration could be faster than an external SAN... But chances are external SAN has alot more scalability as far as adding more controller, cabinets and disks... If it was my choice and you've had great success with SAN's before as mentioned .. stay the route...

RE: NAS vs SAN for data directory
Well, I would avoid NAS as it introduces unwanted overhead when accessing the data. As for SAN versus the internal RAID5, I am not sure, I would say benchmark the two and see which comes out better, or wait to see if there is anyone out there that has dealt with both.

Data Directory
I installed MySQL4.0 source on my redhat7.2 linux server it compiled and make intall fine with no problems execpt that i chose to install it in /databases/mysql/ rather than /usr/local/mysql/ so i did this by typing this instead ./configure --prefix=/database/mysql rather than ./configure --prefix=/usr/local/mysql My problem is, when it was done building and installing, 5 directories were not in the /database/mysql directory but they were in the untared and ungziped directory: the directories are the following scripts,include,support-files,tests,and var. I had to manually copy and paste the directories into the /database/mysql directory. When I executed scripts/mysql_install_db, it ran but the mysql directory was missing mysql/data directory and so was the untared and ungzipped directory basically it was nowhere.

Spontaneous Data Directory Changing
A few weeks ago, my mysql 3.23.46 server spontaneously started changing its data directory to /var/tmp/ once or twice a week, and once or twice a day for a short span. Nothing in the error file.

Hi Mike,
Thanks for the bug report.
The explanation why the insert command doesn't works on Win32,
is because the link file pointing for the DATA DIRECTORY wasn't
created in the create table command, like the Unix version does.
The Win32 OSs don't have a native symbolic link feature and the
today symbolic link support on Win32 is made creating a plain text
file with the extension *.sym on \data directory and contains the
path of the whole database.
Then DATA DIRECTORY feature should be handled in a different way
on Win32 than is made on Unix.

Miguel

Re: data directory.........
If you had read the installation instructions, you would have seen statements that looked like this... cd /usr/local/mysql ./bin/mysql_install_db Make sure that the "var" directory that is created grants access to the 'user' that MySQL is running as... (otherwise I'm sure we'll be getting another Email asking why it still doesn't work...) I'm not being 'sarcastic' or 'disrespectful', it's just that it's almost 1 AM... - Original Message - From: "Usha Rajesh" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Friday, July 27, 2001 12:15 PM Subject: data directory. > Hi, > > I have a problem here. > > I installed mysql-3.23.37 on my linux 2.4.2 i686 box...as specified in the > INSTALL_SOURCE file itself. > > For configure prefix I gave the value of /usr/local/mysql.
