The thing is that I have running GeoServer on a Tomcat 7 instance on my server. I had to install Pentaho BI-Server for data warehouse, but i start the service of Pentaho and immediately GeoServer Services stoped.
I start to wonder what's went wrong and I found that the download of Pentaho has own Tomcat Server. So thats was the problem the tomcat server from pentaho starts and took the ports of Tomcat that was running.
My question is how to configure the two tomcat to work together.
Thanks to all.
The solution gave KNOWARTH is correct, I also guide me the next post to know what ports need to change:
