Posted On 2019-11-30
- OS Version: Redhat 7.5 to 7.6
Using root accout to do all the things.
First you have to register your system
Input your redhat network's ID and Password.
Then check the subscription that you have bought.
subscription-manager list --available
You can use
<code>--all</code> option to show more details, but we only need to know the subscription ID that we bought. Find out the pool ID that we need.
subscription-manager attach --pool=<pool_id>
subscription-manager attach --pool=8axxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
After you attach the pool the
<code>redhat.repo</code>`<code> file which is locate on </code>`<code>/etc/yum.repo.d/</code> will be replaced to Redhat official repository. So you can check what repo we get.
subscription-manager list --consumed
Second you can select the specific version that you want
Using the below command to update your yum db.
yum --releasever=7.6 update
If you only want to update kernel then you can use,
yum --releasever=7.6 update kernel
After upgrading if you don't need keep subscription, you have to unregister.
