Ran into an issue where I was not able to list the installed ZenPacks and Zenoss was having issues starting. I think it was due to a ZenPack having issues and not being installed properly.
Drop into the container
serviced service shell -i -s FixZenpack zope bash
Change user and cd to ZenPack directory
su zenoss cd /opt/zenoss/ZenPacks
Once there, remove the offending ZenPack. Replace ZENPACK.egg with the ZenPack
rm -rf ./ZENPACK.egg
Example:
rm -rf ./ZenPacks.zenoss.MikroTik-1.1.1.egg
Exit out of the container.
exit exit
You can also hit ctrl+d twice.
Commit the Container
serviced service shell -i -s FixZen zope bash
Restart the Zenoss.Core Service
service service restart Zenoss.Core
To remove a ZenPack on Zenoss 5.1 and later, you are going to need to stop the zenoss services, restart a couple services that are needed to install the ZenPack, install the ZenPack, and then restart the Zenoss service.
Stop Zenoss.Core
serviced service stop Zenoss.CoreMake sure the service is stopped by running the following command. When it reports back the Zenoss is Stopped, then continue.
if ( serviced service status Zenoss.Core | awk '{print $3}' | grep -q Stopped) ; then echo "Zenoss is not running!" ; else echo "Zenoss is not Stopped!" ; fi
Or you can run this command, just make sure it says it is stopped.
serviced service status zenoss.core
Create a Snapshot
serviced service snapshot Zenoss.coreStart the following three services
serviced service start Infrastructure
zeneventserver
Zope
serviced service start Infrastructure
serviced service start zeneventserver
serviced service start Zope
List the ZenPacks that are currently installed.
serviced service run zope zenpack list
Remove the ZenPack. Replace “ZenPack.comunity.Zenpack” with the zenpack name from the previous command.
serviced service run zope zenpack-manager uninstall ZenPack.community.Zenpack
This is all contained in the Zenoss Upgrade guide.
Attach to Zope
serviced service attach zope/0 su zenoss
You can run the following commands to check on zenoss
zenossdbpack findposkeyerror zenrelationscan zencatalogscan
zenossdbpack : Quickly scans the Zope Object Database (ZODB) to provide a preliminary indication of the health of the database, and to determine whether the database needs to be compressed with “zenossdbpack” before upgrading.
findposkeyerror : Checks objects and their relationships, and provides options for fixing errors.
zenrelationscan : Checks only ZenRelations between objects.
zencatalogscan : Checks ZODB object catalogs, which speed up web interface access
Skip to the bottom if you just want to see all of the commands.
Make a temporary directory
mkdir /tmp/toolbox cd /tmp/toolbox
Download the tool box
wget https://github.com/zenoss/zenoss.toolbox/archive/master.zip chmod -R 777 /tmp/toolbox
Drop to a shell and switch user
serviced service shell -i -s ToolBox zope bash su zenoss
Install
easy_install /mnt/pwd/master.zip
Exit and commit container
exit exit serviced snapshot commit ToolBox
Restart Zope
serviced service restart zope
All the commands:
mkdir /tmp/toolbox && cd /tmp/toolbox wget https://github.com/zenoss/zenoss.toolbox/archive/master.zip chmod -R 777 /tmp/toolbox serviced service shell -i -s ToolBox zope bash su zenoss easy_install /mnt/pwd/master.zip exit exit serviced snapshot commit ToolBox serviced service restart zope
List Snapshots
service snapshot list
Roll back to snapshot
serviced snapshot rollback SNAPSHOT --force-restart
To install a ZenPack on Zenoss 5.1 and later, you are going to need to stop the zenoss services, restart a couple services that are needed to install the ZenPack, install the ZenPack, and then restart the Zenoss service.
Stop Zenoss.Core :
serviced service stop Make sure the service is stopped by running the following command. When it reports back the Zenoss is Stopped, then continue.
if ( serviced service status Zenoss.Core | awk '{print $3}' | grep -q Stopped) ; then echo "Zenoss is not running!" ; else echo "Zenoss is not Stopped!" ; fi
Or you can run this command, just make sure it says it is stopped.
serviced service status zenoss.core
Create a Snapshot
serviced service snapshot Zenoss.coreStart the following three services
serviced service start Infrastructure
zeneventserver
Zope
serviced service start Infrastructure
serviced service start zeneventserver
serviced service start Zope
Change directory to tmp, make sure you put the zenpack in /tmp
cd /tmp
Install the Zenpack
serviced service run zope zenpack-manager install *.eggExample:
serviced service run zope zenpack-manager install ZenPacks.zenoss.MikroTik-1.1.1.eggRestart the Zenoss Service
serviced service restart zenoss.coreLog into Zenoss and check it.
The following is some commands to try and troubleshoot RabbitMQ not starting in Zenoss 5.
Connecting to the RabbitMQ container
serviced service attach $(serviced service list | grep -i rabbitmq | awk '{print $2}')
Check the service
You can check the RabbitMQ service by running “rabbitmqctl status”
[root@764399e5hhba /]# rabbitmqctl status Status of node rabbit@rbt0 ... Error: unable to connect to node rabbit@rbt0: nodedown DIAGNOSTICS =========== attempted to contact: [rabbit@rbt0] rabbit@rbt0: * unable to connect to epmd (port 4369) on rbt0: nxdomain (non-existing domain) current node details: - node name: rabbitmqct22222@764399e5hhba - home dir: /var/lib/rabbitmq - cookie hash: yy3+awwOpeaaaa12wdf42ff== [root@764399e5hhba /]#
As you can see the node is down so RabbitMQ is not able to start.
Try to ping rbt0 (RabbitMQ connects to rbt0 so if it can’t resolve, then it can’t start)
ping rbt0
If you get a “ping: unknown host rbt0” then add the following to /etc/hosts. Change the IP address to the IP address of the container. You can run “ip addr” or ifconfig to get the IP.
172.20.0.11 rbt0
Or if your interface is eth0, you can run this command.
echo "$(ifconfig eth0 | grep "inet " | awk '{print $2}') rbt0" >> /etc/hosts
Then run “rabbitmqctl status” again. The service auto starts, so it may take a minute, but you should see something similar to the following. (Not that I cut some of the text out.)
[root@764399e5hhba /]# rabbitmqctl status
Status of node rabbit@rbt0 ...
[{pid,4629},
{running_applications,
... CUT TEXT ...
{uptime,5}]
...done.
[root@764399e5hhba /]#
Checking vhost
List the RabbitMQ vhosts with “rabbitmqcl list_vhosts”
[root@764399e5hhba /]# rabbitmqctl list_vhosts Listing vhosts ... / /zenoss ...done.
If you run rabbitmqctl list_vhosts and don’t see /zenoss, then add it
rabbitmqctl add_vhost /zenoss rabbitmqctl set_permissions -p /zenoss zenoss '.*' '.*' '.*'
If the vhost is up then you can try deleting the zenoss vhosts and readding it.
[root@764399e5hhba /]# rabbitmqctl delete_vhost /zenoss rabbitmqctl add_vhost /zenoss rabbitmqctl set_permissions -p /zenoss zenoss '.*' '.*' '.*'
The only downside to theses changes is that once the service gets restarted the changes you made inside the container will be lost, There should be a way to update the container so that the changes are persistent.
#!/bin/bash
# Zenoss 5 backup script
#
#
# CHANGE THESE VARIABLES
# Zenoss 5 Backup log file
log="/root/zenbackup.log"
# Backup directory
bdir="/backup/zenbackup/"
echo "Starting Zenoss backup Script"
echo "Starting backup to ${bdir}." $(date) >> ${log}
echo "Starting Backup to ${bdir}." $(date)
# Stop Zenoss Service
serviced service stop Zenoss.core
wait
# Wait for Zenoss to stop and then continue the backup
while [ -ne `serviced service status Zenoss.core | grep Stopped` ]
do
echo "Waiting for Zenoss to Stop"
sleep 5
done
# Backup
echo "Starting Zenoss Backup"
serviced backup ${bdir}
echo "Backup Finished"
wait
# Start Zenoss
echo "Starting Zenoss"
serviced service start Zenoss.core
echo "Finished backup." $(date) >> ${log}
echo "Finished backup." $(date)
exit
What you need.
First upload you Zenoss 5 backup file, to the “/opt/serviced/var/backps/” directory on the new Zenoss server. Create the directory if it does not exist.
Once the backup file is on the New Zenoss server you will see it listed in the Control Panel’s Backup/Restore tab, you can try to restore it, but if it fails you will need to do the following.
Edit the serviced file “/etc/default/serviced” and uncomment the following line. i.e.(Delete the hash symbol at the beginning of the line).
# SERVICED_REGISTRY=1
Now go to the Control Center, and click restore to start restoring your backup.
It’ll take a little bit to pull the docker images, and get everything setup. In the mean time you could setup your hosts file so you can access Zenoss once it is restored. Refer to this guide under “Setting up name resolution”
Once the Control Center is finished restoring Zenoss, go to the Applications tab, and start the Zenoss Core.
