I've just installed Cent OS 5 on my server and I'm trying to configure it using Webmin. Now I've reached the Apache section and I want to install/uninstall apache modules, but in the apache configuration page cannot see the modules section.
This is very strange. Previously I had Ubuntu and the modules link was there (pic) allowing me to access a page where I could easely enable-disable all the modules I wanted. Now is not :)
How can I fix this?
Thank you!

what you saw on Ubuntu was the Debian-style mods-available/mods-enabled view. CentOS/RHEL does not use that layout. Modules are loaded by plain LoadModule lines in httpd.conf and in extra files under /etc/httpd/conf.d/. That is why Webmin’s list and your httpd.conf do not match. is on the right track: if Webmin is still pointed at Ubuntu paths, it will show toggles that do not change the files Apache actually reads.

Quick fix checklist (CentOS 5):

  • In Webmin -> Apache Webserver -> Module Config, point the Apache config to /etc/httpd/conf/httpd.conf, the server root to /etc/httpd, the httpd binary to /usr/sbin/httpd, and the modules directory to /usr/lib64/httpd/modules on x86_64 (or /usr/lib/httpd/modules on 32-bit). Save, then Refresh Modules in the Webmin Apache page.

Verify where modules really come from and what is active right now:

# Show the main config location Apache is using
httpd -V | egrep 'SERVER_CONFIG_FILE|HTTPD_ROOT'

# Find every LoadModule line in use
grep -R "^LoadModule" /etc/httpd | sort

# Show currently loaded (shared) modules
httpd -M | sort

To enable/disable a module on CentOS, edit the file that actually defines it (often a .conf under /etc/httpd/conf.d/ as installed by the RPM) and add or remove the LoadModule line there. Then test and restart:

apachectl configtest && service httpd restart

Tip: if a module still appears after you commented a LoadModule line, it may be compiled in (listed by httpd -l) or loaded by another file in conf.d/. Match what Webmin shows to the grep results above; once its paths are corrected, leaving "auto-detect modules" enabled usually works best on CentOS.

Have you changed the config to reflect where your CentOS apache files are? Make sure all the config info is updated and you can stop and start apache from within Webmin.

I think everything is fine with the config file, however have noticed something else which makes me more confused.
In the Apache config module, from within Webmin.Apache, these's an option to Always detect Apache modules automatically?. So, it was Yes before and I've set it to No. Now I can see the option to browse to the modules (see pic) but the changes I try to make there (enable/disable) don't save.
So not much of a progress :(

Also confusing for a noob: the Apache modules listed and enabled in the picture above don't match those enabled/disabled in the httpd.conf file. Here's what I have there:
