How to List all Modules Loaded or Enabled in Apache httpd?

Question : Recently, I was learning how to secure Apache web server guide – in which one of the suggestion was to load only necessary modules in Apache, as that will reduce the server load and improves the web server security as well. I would like to know if there’s any command that will list all the modules that are enabled or loaded in Apache? I’m using RedHat enterprise Linux.

Solution: List all Modules Loaded or Enabled in Apache httpd

Yes, there’s a command to list all the modules loaded by Apache.

On RHEL/CentOS:

$apachectl -t -D DUMP_MODULES

(or)

$httpd -M

On Ubuntu:

$ apache2ctl -M

Alternatively, you can verify the modules that are loaded in httpd configuration files.

# vi /etc/httpd/conf/httpd.conf

(or)

Also verify the files inside ‘/etc/httpd/conf.d/‘ and lookout for ‘LoadModule‘.

Similarly, PHP will load lot of modules. The below command will display all modules loaded by PHP.

#php -m
Do you know, 90% of web servers are vulnerable.

Shockingly, you might be one among that, learn to secure your server, website, database & CMS.
