Installing Collectors and Hubs

• Installing for RHEL 5 or CentOS 5

• Installing for RHEL 6 or CentOS 6

5.2.2. Deploying Remote Hubs

The following sections provide detailed information needed to deploy hubs:

• Requirements

• Limitations

• Configuring Zenoss DataStore

• Prerequisite Tasks

• Deployment

5.2.2.1. Requirements

Hub deployments must meet these requirements:

• The Resource Manager server host name must be a resolvable, fully qualified domain name or IP address.

• Any server hosting a remote hub must have the Zenoss DataStore installed (but not running). The Zenoss

DataStore is needed for a client library that allows MySQL connections.

• Remote hubs need to communicate on these default Resource Manager ports:

• Port 13306 - Zenoss DataStore

• Port 8084 - Resource Manager events system

• Port 5672 - Resource Manager queuing system

• You must update all hubs after you:

• Update your version of Resource Manager

• Install patches

• Install, update, or remove ZenPacks

5.2.2.2. Limitations

The system is not compatible with Security-Enhanced Linux (SELinux) in enforcing mode. You must disable

enforcing mode for all platforms running the Resource Manager daemons (Resource Manager master, remote

hubs, and remote collectors).

To disable enforcing mode:

1. Edit the /etc/selinux/config file.

2. Set the following line:

SELINUX=disabled

Note

You also can disable enforcing mode temporarily (avoiding the need to reboot) with the command:

echo 0 > /selinux/enforce

For more information about SELinux, browse to http://en.wikipedia.org/wiki/SELinux, or to the SELinux home

page at http://www.nsa.gov/research/selinux/index.shtml.

5.2.2.3. Configuring Zenoss DataStore for Remote Hubs

Hubs on remote servers need access to the Zenoss DataStore. By default this is set to localhost, but will not

work for remote hubs. Distributed collector attempts to set this field to the fully qualified domain name of the

Resource Manager server when it is installed. If remote hubs appear to be having trouble connecting to the
