Tomcat starts and then stops

[jorgeh]

Greetings,
I am evaluating Zimbra for possible implementation.
I am running Fedora Core 6, and had a couple of snags during the installation, but got past those.
The issue now is, I can start all the services, but then the mailbox stops with the message "Tomcat is not running"
I've looked all through the forums for this issue, and found several references to this, but none appear to apply to me. (I don't even have a redo.log but the parent folder is owned by the zimbra user).
I followed some of the troubleshooting steps and determined (by running sh -x /opt/zimbra/bin/tomcat start) that tomcat does start. I can verify the process is running, but it dies after a few seconds. I see no indication in catalina.out of why this is happening.
Here's the text from catalina.out:

It may be worth mentioning that I'm getting a exception message in the zimbra.log file. here's the partial content:

Can anyone shed some light on this?

You may have verified this already but have you verified that mysql is up and running? If not your real issue may be somewhere else.

[jorgeh]

Thanks for the tip.

I have verified mysql to be running.
It may be worth mentioning also, that I have completly uninstalled / reinstalled the application several times with the same result.

Jorge.

1) I assume you have yet to get Zimbra running ?
2) I assume you have run into the same problem each time?

Check the following:

1) Make sure the system/distribution does not have another version of httpd, tomcat, or mysql running. Typically mysqld will startup early in the boot process and I believe zimbra starts afterward. Mysql will silently fail but zimbra will still probably comeup.

2) If you are sure that the correct mysql and services are running then I would wipe/copy all the logs off somewhere and do a fresh restart of zimbra. Then investigate every logfile. I bet you will see an error somewhere else as well.

[jorgeh]

Thanks,
I tried your suggestion(s).

I ensured there were no servers running prior to installation.

All of the logs appear to be blank or have non-relevant information, with the exception of the information already provided.

Jorge.

Running zmprov returns the following error:

[] INFO: I/O exception (java.net.ConnectException) caught when processing request: Connection refused
[] INFO: Retrying request
[] INFO: I/O exception (java.net.ConnectException) caught when processing request: Connection refused

ERROR: zclient.IO_ERROR (invoke Connection refused, server: localhost) (cause: java.net.ConnectException Connection refused)

Not sure if it's relevant.

Any chance there are policies in iptables that could be affecting MySQL?

Can you connect to MySQL from a command line client?

[jorgeh]

I can connect to MySQL,
Here's the command results:

[zimbra@rufus log]$ mysqladmin status
Uptime: 7169 Threads: 1 Questions: 63 Slow queries: 0 Opens: 11 Flush tables: 1 Open tables: 5 Queries per second avg: 0.009
[zimbra@rufus log]$

I have disabled both firewall ans selinux.

[jorgeh]

The issue has been resolved.
I had a typo in my /etc/host file.

My apologies, and thank you for your suggestions.

At least I can get to the login screen now.

[dlochart]

I am curious as to what type would cause that? Did you have something like this example.

real ip = 192.168.10.1

in DNS
A (address record) zimbra.mydomain.com 192.168.10.1

in /etc/hosts

192.168.10.2 zimbra.mydomain.com
