I recently got a dedicated server package. The server runs CentOS, and comes pre-installed with Apache, PHP, MySQL, as well as Plesk, etc. It seems that they put alot of the nice "extras" such as PHP extensions, CGI support, etc, on the server. I am pretty sure the server also has a nameserver already.
I would like to install Zimbra onto this machine, but from the documentation I got, it seems that the assumption is that the machine being installed onto is "virgin" and that Zimbra will install its own database, PHP, web server, etc. How do I install Zimbra onto an existing server, and have it work with existing applications, without having to replace what is already there? I am pretty sure that over-writing Apache is not a good idea, if I want to use the control panel software given to me.
Is there documentation that outlines how to install Zimbra in already-existing server environments?
My server also has Tomcat installed on it, btw.
