Question

I’ve struggled with this for some time and am definitely doing something wrong.

I have Apache server and a JBoss server on the same machine. I’d like to redirect traffic for mydomain.example to JBoss localhost:8080/example. The DNS is currently setup for mydomain.example and it will go straight to port 80 when entered into the browser.

My question is how do I redirect to a different port when a certain domain name comes to Apache (in this case, mydomain.example)?

<VirtualHost ip.addr.is.here>
  ProxyPreserveHost On
  ProxyRequests Off
  ServerName mydomain.example
  ProxyPass http://mydomain.example http://localhost:8080/example
  ProxyPassReverse http://mydomain.example http://localhost:8080/example
</VirtualHost>

After implementing some suggestions:

• Still not forwarding to port 8080

  <VirtualHost *:80>
    ProxyPreserveHost On
    ProxyRequests Off
    ServerName mydomain.example
    ServerAlias www.mydomain.example
    ProxyPass http://mydomain.example http://localhost:8080/example
    ProxyPassReverse http://mydomain.example http://localhost:8080/example
  </VirtualHost>

You should leave out the domain http://example.com in ProxyPass and ProxyPassReverse and leave it as /. Additionally, you need to leave the / at the end of example/ to where it is redirecting. Also, I had some trouble with http://example.com vs. http://www.example.com – only the www worked until I made the ServerName http://www.example.com, and the ServerAlias example.com. Give the following a go.

<VirtualHost *:80> 
  ProxyPreserveHost On
  ProxyRequests Off
  ServerName www.example.com
  ServerAlias example.com
  ProxyPass / http://localhost:8080/example/
  ProxyPassReverse / http://localhost:8080/example/
</VirtualHost> 

After you make these changes, add the needed modules and restart apache

sudo a2enmod proxy && sudo a2enmod proxy_http && sudo service apache2 restart
