The quickest way to check if apache’s module mod_rewrite is running is by running this command

sudo apache2ctl -M 2>&1| grep -i rewrite

Now, if you want to enable mod_rewrite, run the following command:

sudo a2enmod rewrite

And finally, restart apache server:

sudo apache2ctl restart

ps. Do not forget to set up correct value for the AllowOverride apache directive to enable correct .htaccess behaviour for your code.
