To enable or disable a site on apache we use two commands, a2ensite
and a2dissite
“a2ensite” is used to enable and “a2dissite” is used to disable.
Both commands share same syntax
a2ensite website.com
a2dissite website.com
Where “website.com” is the name of your virtual host configuration file.
After running the commands, restart apache
systemctl restart apache2
