Chapter 9. Manually Installing and Configuring Node Hosts

Procedure 9.1. To Configure Node Host Subscriptions Using Red Hat Subscription Management:

1. Use the subscription-manager register command to register your Red Hat Enterprise Linux system.

   Example 9.1. Registering the System

   # subscription-manager register
   
   Username:
   Password:
   
   The system has been registered with id: 3tghj35d1-7c19-4734-b638-f24tw8eh6246

2. Use the subscription-manager list --available command and locate any desired OpenShift Enterprise subscription pool IDs in the output of available subscriptions on your account.

   Example 9.2. Finding Subscription Pool IDs

   # subscription-manager list --available

   The "OpenShift Enterprise" subscription is the only subscription required for basic node operation. Additional subscriptions, detailed in Section 9.1, “Configuring Node Host Entitlements”, are optional and only required based on your planned usage of OpenShift Enterprise. For example, locate the pool ID for the "JBoss Enterprise Application Platform for OpenShift Enterprise" subscription if you plan to install the JBoss EAP premium xPaaS cartridge.
3. Attach the desired subscription(s). Replace pool-id in the following command with your relevant Pool Id value(s) from the previous step:

   # subscription-manager attach --pool pool-id --pool pool-idsubscription-manager attach --pool pool-id --pool pool-idsubscription-manager attach --pool pool-id --pool pool-idsubscription-manager attach --pool pool-id --pool pool-id

5. Verify that the yum repolist command lists the enabled channel(s).

   Example 9.3. Verifying the Enabled Node Channel

   # yum repolist
   
   repo id                           repo name
   
   rhel-server-6-ose-2.2-node-rpms   Red Hat OpenShift Enterprise 2.2 Application Node (RPMs)

   OpenShift Enterprise node hosts require a customized yum configuration to install correctly. For continued steps to correctly configure yum, see Section 9.2, “Configuring Yum on Node Hosts”.

Procedure 9.2. To Configure Node Host Subscriptions Using Red Hat Network Classic:

1. Use the rhnreg_ks command to register your Red Hat Enterprise Linux system. Replace username and password in the following command with your Red Hat Network account credentials:

   # rhnreg_ks --username username --password passwordrhnreg_ks --username username --password passwordrhnreg_ks --username username --password passwordrhnreg_ks --username username --password password
