Is there a command that list all enabled Apache modules?
To list apache loaded modules use:
apachectl -M
or:
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.

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, ...) – user130370 Nov 6 '13 at 12:44

man apachectlon Ubuntu 20.04 does not include this option (or others), but the command still works. The man page isn't that helpful here – Rory Nov 18 '20 at 12:15
Also you can use server-info to get info from remote servers
<Location /server-info>
SetHandler server-info
Order allow,deny
Allow from 127.0.0.1 xxx.xxx.xxx.xxx
</Location>
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:
http://localhost/server-info
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.

1Why not use the
a2enmodcommand to enable an {installed} module, instead of "symlinking" it manually? – Flo Schild Jun 8 '15 at 8:37 -
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. – rickfoosusa Jun 9 '15 at 14:02

Okay, it works both ways anyway, in 2.4 (maybe already earlier also?) you also have the
a2enconfto symlink files from "conf-available" directory to "conf-enabled" :) – Flo Schild Jun 9 '15 at 14:19
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!
