Appendix A. Updating RabbitMQ Server for
Resource Manager 4.2.2
A.1. About
This document provides information and procedures for updating RabbitMQ Server for systems upgrading from
Zenoss Resource Manager Version 4.x to Version 4.2.2. Using this information, you will update RabbitMQ Server
to Version 2.8.6 or later.
You should follow these procedures if:
• You use custom queues
• Your installation includes Zenoss Service Dynamics Impact and Optimization
• You want to independently update RabbitMQ Server (without upgrading Resource Manager)
Zenoss strongly recommends that you read this document completely before starting the procedures.
A.1.1. Resource Manager Master Connected to Internet
If your Resource Manager master has Internet connectivity, then follow these steps to update RabbitMQ Server:
1. Enter one of the following commands to upgrade to the latest Zenoss dependencies repository:
• For RHEL 5 or CentOS 5:
rpm -Uvh http://deps.zenoss.com/yum/zenossdeps-4.2.x-1.el5.noarch.rpm
• For RHEL 6 or CentOS 6:
rpm -Uvh http://deps.zenoss.com/yum/zenossdeps-4.2.x-1.el6.noarch.rpm
2. Verify that you have visibility on version 2.8.6 of RabbitMQ Server from the zenossdeps-update repository:
yum list rabbitmq-server
You should see output similar to:
...
Installed Packages
rabbitmq-server.noarch 2.1.0-1.el5 installed
Available Packages
>>rabbitmq-server.noarch 2.8.6-1 zenossdeps-update-repo
3. Quiesce all Resource Manager components (remote collectors, hubs, and the Resource Manager master).
Enter the following commands:
On the Resource Manager master
zenwebserver stop
On each remote collector
ssh zenoss@remote-collector
zenoss stop
On each remote hub
ssh zenoss@remote-hub
zenoss stop
On the Resource Manager master
ssh root@master
