Hello there,

mod_expires should come with the default Apache installation, but you can check if the module is both installed and loaded using these commands

  1. apachectl -M | grep expires

If mod_expires is not enabled or installed you can run the following command to install mod_expires on Ubuntu/Debian systems

  1. sudo a2enmod mod_expires

Then you need to restart Apache

  1. service apache2 restart

That’s it, you now have mod_expires enabled.

Hope that this helps!

sudo a2enmod headers
