The Apache web server Can easily be configured to serve up different content based on the name it was called as.

This allows fun stuff like giving your machine multiple names via DNS and making it look like a whole server farm.

This also makes life easier if you're using it to proxy for other machines internal to your network.

In these notes, we'll be setting up 4 names for the server. foo.bar & www.foo.bar which will be the default web site. Wiki.foo.bar which will be served up by the same install of Apache, but still independant of the default web site. Proxy.foo.bar which is on another machine completely & wouldn't otherwise be reachable.

NOTE: It is probably smartest to put the VirtualHost sections in separate files in the /etc/apache2/sites-available/ folder, then make symbolic links to them in /etc/apache2/sites-enabled This will simplify maintenance down the road...

(But, if you really want to, they can simply be added to /etc/apache2/apache2.conf)

A sample set of files for /etc/apache2/sites-available:

  • www.foo.bar.conf
#########################
# WWW.foo.bar           #
#########################

<VirtualHost *:80>
    ServerName foo.bar
    Redirect permanent / https://www.foo.bar/
</VirtualHost>

<VirtualHost *:80>
    ServerName www.foo.bar
    Redirect permanent / https://www.foo.bar/
</VirtualHost>

<VirtualHost _default_:443>
    ServerName www.foo.bar
    DocumentRoot "/var/www/html"
    SSLCertificateFile /etc/letsencrypt/live/www.foo.bar/fullchain.pem
    SSLCertificateKeyFile /etc/letsencrypt/live/www.foo.bar/privkey.pem
    Include /etc/letsencrypt/options-ssl-apache.conf
</VirtualHost>
  • wiki.foo.bar.conf
#########################
# Wiki.foo.bar          #
#########################

<VirtualHost *:80>
    ServerName wiki.foo.bar
    Redirect permanent / https://wiki.foo.bar/
</VirtualHost>

<VirtualHost _default_:443>
    ServerName wiki.foo.bar
    DocumentRoot "/var/www/wiki"
    SSLCertificateFile /etc/letsencrypt/live/wiki.foo.bar/fullchain.pem
    SSLCertificateKeyFile /etc/letsencrypt/live/wiki.foo.bar/privkey.pem
    Include /etc/letsencrypt/options-ssl-apache.conf
</VirtualHost>
  • proxy.foo.bar.conf
##################################
# Proxy for T110.foo.bar    #
##################################

<VirtualHost *:80>
    ServerName proxy.foo.bar
    Redirect permanent / https://proxy.foo.bar/
</VirtualHost>

<VirtualHost _default_:443>
    ServerName proxy.foo.bar
    ProxyRequests on
    SSLEngine On
    SSLProxyEngine On
    ProxyPreserveHost On

    # Redirect WSS traffic (Needed if this is a proxy for ESXi)
    ProxyPass /ticket/ wss://proxy.foo.bar/ticket/
    ProxyPassReverse /ticket/ wss://proxy.foo.bar/ticket/

    # Redirect HTTPS traffic
    ProxyPass / https://proxy.foo.bar/
    ProxyPassReverse / https://proxy.foo.bar/

    SSLCertificateFile /etc/letsencrypt/live/proxy.foo.bar/fullchain.pem
    SSLCertificateKeyFile /etc/letsencrypt/live/proxy.foo.bar/privkey.pem
    <Proxy "*">
        Order allow,deny
        Allow from all
    </Proxy>
        ErrorLog /var/log/apache2/Proxy/proxy_log
        CustomLog /var/log/apache2/Proxy/proxy-access_log combined

</VirtualHost>

create the links

  • cd /etc/apache2/sites-enabled
  • ln -s ../sites-available/www.foo.bar.conf .
  • ln -s ../sites-available/wiki.foo.bar.conf .
  • ln -s ../sites-available/proxy.foo.bar.conf .

and restart Apache:

  • sudo service apache2 restart
