I have an Ubuntu 12.04 server, which had Redmine already installed on a stand-alone apache (everything under /opt/redmine). I wanted to install an instance of Jenkins on the same system, without modifying the existing set-up too much. I want the two services to be accessible under sub.domain.com/redmine and sub.domain.com/jenkins respectively.
I changed Redmines apache to listen on port 8081 instead of 80, installed an additional apache via apt, and set up a virtual host that proxies '/redmine' to localhost:8081/redmine. Thus far everything worked fine. Redmine was accessible as before. However, when I set up Jenkins the same way, with tomcat listening on port 8080, the URL prefix 'jenkins' and a new virtual host, Redmine stops working, i.e. I get a 404. When I remove the Jenkins virtual host, Redmine works again.
Here are the two files under /etc/apache2/sites-available, which I enable/disable via a2ensite/a2dissite.
<VirtualHost *:80> ServerAdmin email@example.com ServerName sub.domain.com ProxyRequests Off <Proxy *> Order deny,allow Allow from all </Proxy> ProxyPreserveHost off ProxyPass /redmine http://localhost:8081/redmine ProxyPassReverse /redmine http://localhost:8081/redmine </VirtualHost>
<VirtualHost *:80> ServerAdmin firstname.lastname@example.org ServerName sub.domain.com ProxyRequests Off <Proxy *> Order deny,allow Allow from all </Proxy> ProxyPreserveHost off ProxyPass /jenkins http://localhost:8080/jenkins ProxyPassReverse /jenkins http://localhost:8080/jenkins </VirtualHost>
I assume there is an issue with one or both of those files. I copied them from a Jenkins tutorial that assumed only a single virtual host. Wherever I look for mod_proxy solutions for multiple hosts, I find examples which map different ports to different domains, i.e. with different ServerNames. But that is not what I want. Do I have to use the RewriteEngine?
