I have multiple instances of tomcat 6 running on the same server (Linux) and it works as expected. I am trying to find out what the standard practice is with regards to setting the CATALINA_HOME
and CATALINA_BASE
variables.
In my tomcat installation, I have setup CATALINA_HOME
to point to a "common" folder (say /tomcat6
) and the CATALINA_BASE
variable varies depending on the instance name (say /tomcat_instance1
, /tomcat_instance2
)
My question is this:
CATALINA_HOME
and do away with
CATALINA_BASE
(or vice-versa) ?If you are running multiple instances of Tomcat on a single host you should set CATALINA_BASE
to be equal to the .../tomcat_instance1
or .../tomcat_instance2
directory as appropriate for each instance and the CATALINA_HOME
environment variable to the common Tomcat installation whose files will be shared between the two instances.
The CATALINA_BASE
environment is optional if you are running a single Tomcat instance on the host and will default to CATALINA_HOME
in that case. If you are running multiple instances as you are it should be provided.
There is a pretty good description of this setup in the RUNNING.txt
file in the root of the Apache Tomcat distribution under the heading Advanced Configuration - Multiple Tomcat Instances
