How to setup an Apache Virtualhost as proxy

If you want to use apache to set a virtualhost and to use it as proxy, to pass one or more localhosts to internet, all you have to do is to follow few simple rules described below:

1. create file /etc/apache2/sites-available/VIRTUALHOST_NAME.conf
2. sudo a2ensite virtual_host_file_name

• to disable an existing conf file sudo a2dissite virtual_host_file_name

1. move file in /etc/apache2/sites-enabled/VIRTUALHOST_NAME.conf
2. install ssl module sudo a2enmod ssl
3. sudo service apache2 reload

Other commands for apache:

• show all modules installed apache2ctl -M
• show logs sudo systemctl status apache2.service
