Subject RE: [users@httpd] Documentation for /etc/sysconfig/httpd file
Date Thu, 04 Jun 2015 00:09:12 GMT
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.

well, had you redirected the OP to some shell scripting list, I'd have agreed, but...

...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.

Jens
