Brainstorming is not really required for this basic task. Approach 1: Make a copy of your Tomcat installation, alter bootstrap, http and ajp connector ports, and use it as 2nd instance. Approach 2, using one physical Tomcat installation: You can configure n instances using CATALINA_BASE setup, each running separate JVM process.
Johann Von: Jerry Malcolm Gesendet: Freitag, 22. Februar 2019 07:27 An: users@tomcat.apache.org Betreff: Parallel Tomcat Instances On Same Server I need a bit of brainstorming. I have a production Tomcat server that hosts several web sites. A couple of these websites are high-availability sensitive. Any downtime will cost the customer. So obviously I want to minimize downtime. On the other hand, I am always adding/removing/testing other virtual hosts which requires configuration changes and periodic reboots of Tomcat. I'm not at CPU capacity or memory capacity on the box. So that is not the problem. What I'd really like to do is run both a production TC instance AND a 'development/test' TC instance on the same box with the luxury of bouncing or taking the dev TC down any time necessary without affecting the production TC. I'm using Apache httpd as the front end and routing via mod_jk to TC. The separation of function on the two instances would be at domain level. Domain A runs on production, Domain B runs on dev. I am using the basic mod_jk worker config currently. If I change the dev instance to run a different port, is it simply a matter of having worker1 and worker2 that route to the different TC instances, and assign either worker1 or worker2 to each virtual host in httpd? I figure some people have done this in the past. Is this the easiest way to do this? Is there a better way? Thx as always.
