Is there a command that list all enabled Apache modules?

7 Answers 7


To list apache loaded modules use:

apachectl -M


apachectl -t -D DUMP_MODULES 

or on RHEL,CentoS, Fedora:

httpd -M

For more options man apachectl. All these answers can be found just by little google search.

    -M will also work.

    I love this comment about google search (found this answer via google)

    The use of server-info is harder to find via google and gives much more details && the ability to give access to the information to people who don't have shell access (eg client, web developpers, project managers, ...)

  • man apachectl on Ubuntu 20.04 does not include this option (or others), but the command still works. The man page isn't that helpful here Nov 18, 2020 at 12:15
  • Prefix command with sudo e.g. sudo httpd -M if you get errors like local ssl cert not found etc. Its due to permission issue. Jun 29, 2022 at 14:17

Also you can use server-info to get info from remote servers

<Location /server-info>
   SetHandler server-info
   Order allow,deny
   Allow from xxx.xxx.xxx.xxx

You can get list of all enabled Apache modules at http://your.host.example.com/server-info?list


You need to enable the info module:

sudo a2enmod info.load
sudo a2enmod info.conf
sudo service apache2 restart

After restart:


will provide a long list of modules, and configuration info.

To view from remote servers, you can change the 'Requires' option in /etc/apache2/mods-available/info.conf to allow remote servers to view info.

    Why not use the a2enmod command to enable an {installed} module, instead of "symlinking" it manually?

  • Yes a2enmod is more correct. When I'm editing configs I usually stay with the files and don't think of the specialty commands that I rarely use. Jun 9, 2015 at 14:02
  • Okay, it works both ways anyway, in 2.4 (maybe already earlier also?) you also have the a2enconf to symlink files from "conf-available" directory to "conf-enabled" :)

On more recent iterations of Debian and Ubuntu there is also the a2query command:

a2query -m
authz_host (enabled by maintainer script)
ssl (enabled by site administrator)


Usage: /usr/sbin/a2query -q -m [MODULE] -s [SITE] -c [CONF] -a -v -M -d -h
-q              suppress any output. Useful for invocation from scripts
-m [MODULE]     checks whether the module MODULE is enabled, lists all enabled
modules if no argument was given
-s [SITE]       checks whether the site SITE is enabled, lists all sites if no
argument was given
-c [CONF]       checks whether the configuration CONF is enabled, lists all
configurations if no argument was given
-a              returns the current Apache 2 module magic version
-v              returns the current Apache 2 version
-M              returns the enabled Apache 2 MPM
-d              returns the Apache 2 module directory
-h              display this help

    a2query -m is a gem! Thanks!

This works also:

apache2ctl -M

The above answers are old and no longer work for my modern Fedora Server 31 / 32 and Apache 2.4.

Here's what does:

httpd -t -D DUMP_MODULES

But, there is a caveat that this will only work if you have an appropriately configured /etc/httpd/conf/httpd.conf, so if you're in the middle of editing to set LogLevel, it won't work if your edits are in-progress and not valid!


Ubuntu 22.04 LTS:

sudo a2enmod info.load
sudo service apache2 restart

After restart:

sudo wget http://localhost/server-info --no-check-certificate && cat server-info
