Re: [users@httpd] Documentation for /etc/sysconfig/httpd file
Hi Dirk, Zitat von Dirk Devos : So, if I understand this correctly I should be putting my changes in "/usr/sbin/apachectl" and not "/etc/sysconfig/httpd". this depends on your distribution's setup. In my case I can see that apache(2)ctl does *source* /etc/sysconfig/apache2, which would be then the proper place for local customization. How your distro handles this, is something you will have to find out (i.e. by looking at your apachectl script). So if I want to have a variable available to me in httpd.conf that contains the server's host name that I am running on, what do I need. I have tried variable=$(hostname) and variable=`hostname` and when I use that variable in httpd.conf is always resolves to the actual literal "$(hostname)" or "`hostname`". Why your variables aren't set properly is a different (shell scripting) story, maybe running your script via "set -x" will give you a clue.

The naming convention for our hostnames tells us if it is a development server
or a production server. I want to use that to create http.conf files that are
more generic across all our apache servers.

Couple of starter points
1) the apache httpd project is not responsible for the distribution
specific builds. The /etc/sysconfig/httpd thing is a red hat-ism.
2) you should contact red hat for support on that
In general /etc/sysconfig/httpd (which at some point will be deprected
-it already is with fedora as systemd generally doesn't use
/etc/sysconfig files) are simply ./sourced into the init script
environment. So if the particular VARNAME value is actually USED by the
distro init scripts and passed into it's httpd configuration, it will be
used. If it's not, then it doesn't actually have any impact at all. So
you'll want to look more closely at the init script and the httpd
configuration files to even know if what you're trying to do in
/etc/sysconfig/httpd is doable.

Re: [users@httpd] Documentation for /etc/sysconfig/httpd file
Hi Dirk, Zitat von Dirk Devos : I am confused. Based on the documentation on apache's website we need to use "apachectl" but in that module it says to use "apachectl". So what is the right place. hm, looks identical to me ;) And on a random machine I picked to look things up, it's "apache2ctl" :D I realize that the variables are different and that was done on purpose. I wanted to compare the two ways of assigning a value. and what happens if you dynamically assign a value to the variable that's currently working statically and vice versa? To me it looks like you have to find out if either a - it's a problem assigning the value (including finding the right place to do so), which is more of a "shell programming" question, or b - it's a problem of accessing the content of a shell variable from where you're trying to do so (which might be an httpd question) Regards, Jens - To unsubscribe, e-mail: users-unsubscr...@httpd.apache.org For additional commands, e-mail: users-h...@httpd.apache.org
RE: [users@httpd] Documentation for /etc/sysconfig/httpd file
I am confused. Based on the documentation on apache's website we need to use
"apachectl" but in that module it says to use "apachectl". So what is the right
place.
I realize that the variables are different and that was done on purpose. I
wanted to compare the two ways of assigning a value.
** From http://httpd.apache.org/docs/2.4/programs/apachectl.html
apachectl is a front end to the Apache HyperText Transfer Protocol (HTTP)
server. It is designed to help the administrator control the functioning of the
Apache httpd daemon.
The apachectl script can operate in two modes. First, it can act as a simple
front-end to the httpd command that simply sets any necessary environment
variables and then invokes httpd, passing through any command line arguments.
Second, apachectl can act as a SysV init script, taking simple one-word
arguments like start, restart, and stop, and translating them into appropriate
signals to httpd.
If your Apache installation uses non-standard paths, you will need to edit the
apachectl script to set the appropriate paths to the httpd binary. You can also
specify any necessary httpd command line arguments. See the comments in the
script for details.
The apachectl script returns a 0 exit value on success, and >0 if an error
occurs. For more details, view the comments in the script.
** So I found the "apachectl" file in "/usr/sbin/" and in the file I
found the following.
if [ "x$2" != "x" ] ; then
echo Passing arguments to httpd using apachectl is no longer supported.
echo You can only start/stop/restart httpd using this script.
echo If you want to pass extra arguments to httpd, edit the
echo /etc/sysconfig/httpd config file.

just for the records, you'll see that with SUSE Linux Enterprise
(SLES) as well, at least up to (still widely used) SLES11.

...obviously he already found a working way of setting the value statically,
but didn't manage to do so dynamically. Hence I thought it polite to point out
that mismatch in variable names between these two variants.

[users@httpd] Documentation for /etc/sysconfig/httpd file
Hi,
I am running Redhat 7.1 and apache 2.4 but I am not able to find any
documentation on the "/etc/sysconfig/httpd" file.
I am new to apache and I am trying to save the value of "uname -n" to a
variable and from what I was reading the place to set the value would be in
the "/etc/sysconfig/httpd" file.
I was able to assign a constant value to a variable but I would like to get
the name of the server that is running the httpd daemon so that I can use
regex to determine if I am running in development or production.
This works.
HTTPD_ENV_NAME="devl"
I have tried the following with no success.
HTTPD_HOSTNAME=`hostname`
HTTPD_HOSTNAME=${hostname}
HTTPD_HOSTNAME=$(hostname)
Any help on what I am doing wrong would be appreciated.
