Apache

Creating a virtualhost with reverse proxy

Add library and enable modules

sudo apt-get install libapache2-mod-proxy-html
sudo a2enmod proxy proxy_http proxy_connect proxy_html xml2enc

Restart

sudo service apache2 restart

Add a new virtualhost file, like /etc/apache2/sites-available/site-proxy.conf

<VirtualHost *:80>
    ServerAdmin hostmaster@example.com
    ProxyRequests off
    DocumentRoot /var/www
    ProxyPreserveHost On

    # Set the URL used on live env
    ServerName example.com

    # If more than one URL will be used,
    # add here one per line
    ServerAlias www.example.com

    ErrorLog ${APACHE_LOG_DIR}/error.log
    CustomLog ${APACHE_LOG_DIR}/access.log combined

    # Possible values: debug, info, notice, warn, error, crit,
    # alert, emerg.
    LogLevel error

    <Location />
        # Site URL to be accessed
        ProxyPass http://internal.example.com:8444/
        ProxyPassReverse http://internal.example.com:8444/
        Order allow,deny
        Allow from all
    </Location>
</VirtualHost>

Add this virtualhost to Apache

sudo a2ensite site-proxy

Restart Apache (again)

sudo service apache2 restart
