View source for Troubleshooting Tomcat

{{Archive}}{{Article Infobox|{{admin}}|||{{ZCS 4.5}}}}A common symptom of Tomcat not starting (you see the error message "tomcat is not running" below the mailbox status) when you call <br>
$> '''su - zimbra; zmcontrol status''<br> is incorrect permissions on the /opt/zimbra/redolog/redolog<br>

To check if this is the case, <br>
$> '''su - zimbra''' <br>
% The correct way to switch to the Zimbra user<br>
$> '''ls -l /opt/zimbra/redolog'''<br>
% Lists the permissions of the redolog directory. <br>

You may see an entry similiar to this <br>
'''-rw-r-----  1 root root 3925 Sep 26 01:59 redo.log'''. <br> 
This is the 'incorrect' permissions. (The author has tested that this can be mistakingly set to root even if you always work with zimbra as the zimbra user)<br><br>

If you find the permissions set to something similiar as above (not the zimbra user and group) then switch to the root user and change the permissions<br>
$> '''su - root'''<br>
% Switches to the root user.<br>
$> '''chown zimbra:zimbra /opt/zimbra/redolog/redo.log'''<br>
% Changes user and group ownership of the file 'redo.log' to zimbra<br>
% Alternativly you can use sudo like $> '''sudo chown zimbra:zimbra /opt/zimbra/redolog/redo.log'''<br><br>

After you are done changing the permissions, verify you have done what you intended<br>
$> '''ls -l /opt/zimbra/redolog'''<br>
%Shows the permission of the files and directories in the 'redolog' directory<br>

The line should read something similiar to<br>
'''-rw-r-----  1 zimbra zimbra 3925 Sep 26 01:59 redo.log'''<br>
%Correct file permission, note the zimbra zimbra which corresponds to the zimbra user and zimbra group<br><br>

After you verfiy it is owned by the zimbra user and group restart the server with <br>
$> '''su - zimbra'''<br>
%Switches (back) to the zimbra user so that permissions are not scrambled.<br>
$> '''zmcontrol stop'''<br>
% Stops the zimbra pim system completely<br>
$> '''zmcontrol start'''<br>
% Starts the zimbra pim system<br><br>

Finally check to see if tomcat is indeed started<br>
$> '''zmcontrol status'''<br>
% Lists the zimbra components' status<br><br>

You should no longer see the error message "tomcat is not running"<br><br>
