Can't start tomcat6 on Fedora12, how to allow through firewall?

  • 772

I've got a fedora 12 system, and have installed tomcat6 via yum.

I can start tomcat by issuing: tomcat6 start

I can see this is OK by the catalina.out log file as follows

Nov 20, 2009 11:05:08 PM org.apache.catalina.core.AprLifecycleListener init

I have changed the port for tomcat to 8888 as 8080 is in use elsewhere, I have changed this in server.xml as follows

 <Connector port="8888"
            protocol="HTTP/1.1" 
            connectionTimeout="20000" 
            redirectPort="8443" />

I can't get anything on http://localhost:8888 in any browser, I'm thinking that the firewall could have been blocking tomcat. I've disabled the firewall temporarily in system-config-firewall and restarted tomcat, but that doesn't seem to change anything

What else could be stopping access to tomcat? There is nothing in /var/log/messages regarding tomcat other than the yum install logging

firewall

  1. If you have sufficient privs, try

    netstat -an | grep LIST

    and see if there is actually anything listening on port 8888. If so, try "127.0.0.1:8888" in your browser where you are now trying "localhost".

    I wouldn't have thought the firewall would block loopback connections, but just in case: are you sure it's disabled? Try running (as root): /etc/init.d/iptables stop

    Also, are you sure the Tomcat process is still running? Check with: ps aux | grep java
