This article is about how installed Tomcat 7 on Red Hat 7. This is the way I have found to work the best in my environment. Other people might disagree and I guarantee there is a 100 different ways to do this but this works for me. I have a lot tomcat servers running under heavy loads and have had close to zero downtime. The only reason for downtime on these server is from environmental factors not the servers themselves. Example power went out and the UPS blew a capacitor at the same time. That sucked but things like that make life exciting. I just want to clarify no physical server has zero down time. My Vmware servers are zero down time but its comprised of several servers. Well lets started.
