= Preparing a RHEL compute node

|
Before you add a Red Hat Enterprise Linux (RHEL) machine to your {product-title}
|
|
cluster, you must register each host with Red Hat
|
|
Subscription Manager (RHSM), attach an active {product-title} subscription, and
|
|
enable the required repositories.
|
|
|
|
. On each host, register with RHSM:
|
|
+
|
|
----
|
|
# subscription-manager register --username=<user_name> --password=<password>
|
|
----
|
|
|
|
. Pull the latest subscription data from RHSM:
|
|
+
|
|
----
|
|
# subscription-manager refresh
|
|
----
|
|
|
|
. List the available subscriptions:
|
|
+
|
|
----
|
|
# subscription-manager list --available --matches '*OpenShift*'
|
|
----
|
|
|
|
. In the output for the previous command, find the pool ID for an {product-title} subscription and attach it:
|
|
+
|
|
----
|
|
# subscription-manager attach --pool=<pool_id>
|
|
----
|
|
|
|
. Disable all yum repositories:
|
|
.. Disable all the enabled RHSM repositories:
|
|
+
|
|
----
|
|
# subscription-manager repos --disable="*"
|
|
----
|
|
|
|
.. List the remaining yum repositories and note their names under `repo id`, if any:
|
|
+
|
|
----
|
|
# yum repolist
|
|
----
|
|
|
|
.. Use `yum-config-manager` to disable the remaining yum repositories:
|
|
+
|
|
----
|
|
# yum-config-manager --disable <repo_id>
|
|
----
|
|
+
|
|
Alternatively, disable all repositories:
|
|
+
|
|
----
|
|
yum-config-manager --disable \*
|
|
----
|
|
+
|
|
Note that this might take a few minutes if you have a large number of available repositories
|
|
|
|
. Enable only the repositories required by {product-title} {product-version}:
|
|
+
|
|
----
|
|
# subscription-manager repos \
|
|
--enable="rhel-7-server-rpms" \
|
|
--enable="rhel-7-server-extras-rpms" \
|
|
--enable="rhel-7-server-ose-4.1-rpms"
