Download tomcat, and unpack it twice, into two separate directories. Edit the conf/server.xml file in one of the copies in the following way: Change the port on the root Server element to a different number (e.g. 8006) Change the port attributes on the Connector elements to a different number (e.g. 8010 instead of 8009, 8081 instead of 8080 and 8444 instead of 8443) You should now be able to run the bin/startup.sh scripts in both installations to get two running tomcats. Connect using port 8080 and install the basic application services, and then connect using port 8081 to install the service provider management services. Source link.
