How to load the modules for Apache2?

Solution 1:

You can enable modules using a2enmod. For example:

a2enmod proxy

That command will create a symlink inside /etc/apache2/mods-enabled that points to the module in /etc/apache2/mods-available.

Likewise, to disable a module, use a2dismod. That command will remove the symlink from the mods-enabled directory.

Bonus tip: there exist similar commands to enable/disable sites: look at a2ensite and a2dissite.
