Is subscription-manager available for CentOS?

Solution 1:

subscription-manager for CentOS 6 is available

wget -O /etc/yum.repos.d/epel-rhsm.repo http://repos.fedorapeople.org/repos/candlepin/subscription-manager/epel-subscription-manager.repo
yum install subscription-manager -y

Solution 2:

Yes, the subscription-manager tool is Red Hat-specific, allowing you to manage Red Hat subscriptions. Since CentOS doesn't have subscriptions, CentOS 6 omitted this tool.

CentOS 7 now includes subscription-manager, which you can use with Red Hat Satellite or its open source versions Spacewalk or Foreman/Katello.

Solution 3:

Yes, it is available.

If you have an environment with Red Hat Satellite or Foreman ( the Opensource version of satellite 6) it is very useful.

You will be able to see your client systems and all the details (like dmidecode) on the satellite or Foreman.
