OK. I just tried that. Tomcat is now responding on port 8888. However, when I attempt to login I get the following error in the login box:
An unknown application error has occurred. Please correct any errors and retry. If the problem persists, please contact your System Aministrator. (AjxException.INVALID_PARAM)
The exact command that I ran was:
$ zmprov
prov> ms myserver.domain.com zimbraMailPort 8888 zimbraMailSSLPort 8889
tomcat stop
tomcat start
After getting the error above, I then tried zmcontrol stop and zmcontrol start.
I went back into zmprov and ran GetConfig zimbraMailPort
This returned that it was still using 80. I'm not sure if maybe "zmprov GetConfig" reads a saved copy of the config or not, but in any case I tried to change it again:
zmprov ms myserver.domain.com zimbraMailPort 8888
zmprov GetConfig zimbraMailPort still returns port 80. I then reviewed the /opt/zimbra/tomcat/conf/server.xml and verified that although the zmprov didn't see to show me the correct zimbraMailPort, that the server.xml was actually changing. So in there it changed to port 8888 and redirect to SSL port 8889.
After I did all of the above stuff, I tried hitting
http://myserver.domain.com:8888. I just get the apache test page.
Do I need to use zmprov in addition to doing some other steps?
Thanks for the quick reply, btw.
