2.3. Enabling the Required Repositories
To install packages signed by Red Hat you must register the target system to the Content Delivery Network. Then, use an entitlement from your subscription pool and enable the required repositories.
Enabling the Required Repositories Using Subscription Manager
Register your system with the Content Delivery Network, entering your Customer Portal user name and password when prompted:
# subscription-manager register
Locate the relevant subscription pools and note down the pool identifiers:
# subscription-manager list --available
Use the pool identifiers to attach the required subscriptions:
# subscription-manager attach --pool=pool_id
When a system is attached to a subscription pool with multiple repositories, only the main repository is enabled by default. Others are available, but disabled. Enable any additional repositories:
# subscription-manager repos --enable=repository
Ensure that all packages currently installed are up to date:
# yum update
