--------------------------------------------------------------
I cannot start Zenoss on my Centos 6.3 x64 after using the install script. The only thing I can think of that might be causing this is that I am behind a proxy that I might need to communicate via.

Below are the errors I receive in the console when running Service zenoss start:


Daemon: zopectl daemon manager not running
Daemon: zeneventserver stopping...

I have also tried to remove the zenpack_actions.txt to prevent loading of any zenpacks. However I then get this in my browser when going to the Zenoss url:

ubrob:

You may be running into the same issue/error that I encountered. I have a blog post for a fresh Zenoss Core 4 on CentOS 6 that may help ( http://binarynature.blogspot.com/2012/11/zenoss-core-4-installation.html http://binarynature.blogspot.com/2012/11/zenoss-core-4-installation.html ). Refer to the 'Start Zenoss' section about the *set-rabbitmq-perms.sh* script.

So, you used the auto-deploy script to install this and it ran clean?

Check Marc's excellent suggestion.  If that doesn't fix it, as the root user, try running rabbitmqctl as shown below:


[***@zen42 student]# rabbitmqctl -p /zenoss list_queues
Listing queues ...
celery    0
zen42.celeryd.pidbox    0
zenoss.queues.zep.migrated.summary    0
zenoss.queues.zep.migrated.archive    0
zenoss.queues.zep.rawevents    0
zenoss.queues.zep.heartbeats    0
zenoss.queues.zep.zenevents    0
zenoss.queues.zep.modelchange    0
zenoss.queues.zep.signal    0
...done.
[***@zen42 student]#

If you get similar output then your MQ queues are OK.  If not, look towards the end of the Zenoss Admin Guide in
Section 14.8 "Host Name Changes" for some commands to reset your rabbit MQ environment.

NB===NB===NB

If this is Zenoss 4.2.3 installed with the auto-deploy script or has had the secure_zenoss.sh script run standalone, then the password required for the following fix will NOT be zenoss in line 3 below..

export VHOST="/zenoss"
export USER="zenoss"
export PASS="zenoss"
rabbitmqctl stop_app
rabbitmqctl reset
rabbitmqctl start_app
rabbitmqctl add_vhost "$VHOST"
rabbitmqctl add_user "$USER" "$PASS"
rabbitmqctl set_permissions -p "$VHOST" "$USER" '.*' '.*' '.*'

Check the amqppassword in $ZENHOME/etc/global.conf and use that instead of zenoss.

When you have run through these as root, as the zenoss user, do a:
zenoss stop
zenoss start

As the root user, recheck your queues with:
rabbitmqctl -p /zenoss list_queues

Cheers,
Jane
