Installing Sonar and Jenkins on Tomcat

问题:

I have a tomcat server and I wish to install Jenkins and Sonar on it. I am on a debian distibution, therefore I got tomcat6 and Jenkins via apt-get. When I copy the jenkins.war to my tomcat6/webapps directory, everything runs fine. However when I copy the sonar.war to tomcat6/webapps, sonar works fine, but jenkins throws an error 500:

javax.servlet.ServletException: org.apache.commons.jelly.JellyTagException: jar:file:/var/lib/tomcat6/webapps/jenkins/WEB-INF/lib/jenkins-core-1.435.jar!/hudson/model/View/index.jelly:39:43: <st:include> PermGen space

I've also install the manager (tomcat6-admin) and the manager is failing too when i add the sonar.war.

I've installed sonar by downloading it from codehaus, setting the database configuration and building the war.

Does anyone know why this is happening and might have a solution?

回答1:

In your exception, it appears :

PermGen space
org.kohsuke.stapler.jelly.JellyClassTearOff.serveIndexJelly(JellyClassTearOff.java:112) 

There's a problem with the permgen :

This error occurs when the JVM runs out of space in the permanent generation heap

To fix the error, you need to put the -XX:MaxPermSize=<Y>m (where <Y> is the memory you want) in the CATALINA_OPTS environment variable.

How do you achieve this ? Follow this article (for example) :

How can I increase memory in my application server ?

回答2:

I had this configured on a RHEL server with 8Gb RAM. I found I needed (in catalina.sh or the non-interactive shell running tomcat) VM options of -Xms1024m -Xmx2048m -XX:PermSize=256m -XX:MaxPermSize=512m

I also needed to reset the Executor maxThreads, and minSpareThreads in the conf/server.xml file (400, and 50 respectively), otherwise the server crawled.

By the way, if you're using Virtual Servers, you could try an already configured VM, SecureCI, which sets up a complete Maven/Jenkins/Sonar CI environment out of the box. There's no configuration if your build relies on Maven.
