Here’s a short guide for installing Confluence on a shared Tomcat server instance on Ubuntu 8.10. Apache Tomcat 6 can be installed using a simple apt-get command:
sudo apt-get install tomcat6
Next, we’ll need to raise the Tomcat heap size for confluence. Edit /etc/default/tomcat6 and add the line:
JAVA_OPTS="-Xms128m -Xmx1024m -XX:MaxPermSize=256m $JAVA_OPTS -Djava.awt.headless=true"
Now, we’ll need to grant security permissions to the Confluence webapp. To do this, create a file /etc/tomcat6/policy.d/05confluence.policy and place the following text in it:
grant codeBase "file:${catalina.home}/webapps/confluence/-" {
permission java.security.AllPermission;
};
grant {
permission java.lang.RuntimePermission "accessDeclaredMembers";
permission java.lang.reflect.ReflectPermission "suppressAccessChecks";
permission java.lang.RuntimePermission "defineCGLIBClassInJavaPackage";
};
Finally, we can restart Tomcat using the command:
/etc/init.d/tomcat6 restart
