Stop Services Via SSH Hangs...

[mlissner]

EDIT: Title should be Start Services via SSH Hangs! Oops...

I'm trying to write a backup script from one computer to another that will log into the zimbra server, stop services, log out, back it up, log back in, start services, and then log out again.

Everything works peachy, except starting the services again. The script that is doing that looks like this:

#!/bin/bash

# This script should simply start the zimbra server.

#Login as root to the zimbra server
ssh -T root@192.168.1.132  <<NOMORE

#Start the zimbra server
su - zimbra
zmcontrol start

#Log out of the zimbra server
NOMORE

exit 0

The problem I am having is that it gets most of the job done like so:

### ZimbraStart.sh 
Host mail.michaeljaylissner.com
	Starting ldap...Done.
	Starting logger...Done.
	Starting mailbox...Done.
	Starting antispam...Done.
	Starting antivirus...Done.
	Starting snmp...Done.
	Starting spell...Done.
	Starting mta...Done.

But then it just hangs there after that last line. The script doesn't end, and thus the backup is not successful.

Any thoughts about why it would just hang once it was NEARLY complete?

I'm not sure why it's hanging, but to return to the shell immediately after executing you could use this line (just append an ampersand on the end):

zmcontrol start &

Or alternatively, to check the status once complete (useful in log files):

zmcontrol start; zmcontrol status

[uxbod]

does the same happen if you do

su - zimbra -c 'zmcontrol start'

what appears in /var/log/zimbra.log when this happens ?

IIRC there are problems with some distributions and using 'su', the following seems to work:

sudo -u zimbra /opt/zimbra/bin/zmcontrol stop

@webman - Yeah, I thought about that, but that command is part of the backup script, so if I add & to the end of that line, it will run in the background, and the backup might start prematurely...

@uxbox - yeah, tried that. No dice...

@pheonix - I didn't try it with the entire command written out like that, but I did try sudo -u zimbra zmcontrol start....which had the same problem. I will try this tonight and post again, though I'm not optomistic at the moment.

#!/bin/bash

# This script should simply start the zimbra server.

#Login as root to the zimbra server
ssh -T root@192.168.1.132  <<NOMORE > /tmp/ssh.log 2>&1

#Start the zimbra server
su - zimbra
zmcontrol start

#Log out of the zimbra server
NOMORE

exit 0

I added redirection on the script to see if that has any effect.

Well, I figured out how to fix this. I upgraded to the latest version of Zimbra, and tried the script again. All better.

Yeah, I tried that too (not that it makes much sense), but it didn't seem to work...odd...
