I am currently in the middle of an upgrade from Apache (2.2)/Tomcat (5.5.16) to Apache (2.2)/Tomcat (6.0.24). The JVM is being upgraded from 1.5.0_09-b01 to 1.6.0_22-b22. The new host servers will be RedHat 6.2.
I would like to use the default application installation paths used by the RPMs. However, I would like the user code base(s) to exist in a separate partition. These servers will be hosting multiple separate java applications. Currently Apache and Tomcat use mod_jk as the connector. I am hoping for some advice that will help me with the server/Tomcat/Apache configuration. I am specifically interested in Tomcat configuration advice, or direction. I would like to get some clarification on the following questions: How can I configure Tomcat to allow each individual application (JVM) to be restarted independently? - We currently do this with separate CATALINA_BASE directories, and separate startup/shutdown scripts. I’m not sure if that is the cleanest way. What method would best allow Apache to serve static content, and Tomcat to server java based dynamic content? - I’m assuming this will depend on the connector used. Which connector (mod_jk, mod_proxy_ajp, mod_cluster) should be used? - I have heard conflicting reports about mod_jk being deprecated or not. - I have seen benchmarks with mod_proxy_ajp outperforming mod_jk significantly. - I don’t think we currently need the clustering functionality of mod_cluster, but may with future JBoss installations. Thanks in advance for your suggestions.
