5.3.4.1 RHEL 8 System registered through the subscription manager
To enable the subscription to the RHEL system in Red Hat, it is recommended to provide a specific hostname to the server in the cluster. In this example, we will change the Host name to ecmukdemo10.
This procedure must be followed logged in as the root administration user:
su – root
Choose the domain name. We can use the Company Domain name, asbsoftware.co.uk. (Registered to ASB Software Development Limited).
To set a Fully Qualified Domain Name (FQDN):
hostnamectl set-hostname ecmukdemo10.asbsoftware.co.uk
The system is then registered as follows. This can be accomplished in one step by using the following command:
subscription-manager register –username username –password password –auto-attach
Where you should change username and password with the username and password used for the RHEL Red Hat login. Once the subscription command has been run, the enabled repositories can be reviewed by using the following command:
yum repolist
If you want to enable more repositories for your RHEL installation, you can edit the following file:
vi /etc/yum.repos.d/redhat.repo
Within that file, you will see a long list of available repos. To enable a repo, change 0 to 1 opposite the required repo enabled = option.
The yum repolist command can then be used to list all the available repos.
5.3.4.2 Red Hat CentOS 8.0 Streaming
The base Centos 8.0 screenshots for this section can be found on pages 12 to 22 of the document, CENTOS8-0InstallationForIBMCloudPrivateandIBMFileNetP8CPITInstallationV2.docx

IBM Cloud Private P8 Container CPIT Installation on CENTOS Linux 8.0.
5.3.4.3 CENTOS 8 download and install
Note: the VMware Workstation support for CENTOS 8.0 only starts with VMware Workstation Pro version 15.1.0, so this needs to be installed as a minimum version upgrade (or a newer installation) first!
NB This is through the VMware support for the RedHat Enterprise Linux 8.0 option as CENTOS 8-Stream is 100 % compatible, at least as far as VMWare is concerned.
CentOS Linux 8.0 support will end at the end of 2024(for maintenance updates). CentOS 8 Stream will completely replace CentOS 8.x Linux. CentOS stream will be directly integrated with Red Hat providing a direct line to RHEL developments. The stability of CentOS 8 Stream should be effectively the same as downstream CentOS 8.0 for most users. CentOS 8 Stream is literally just the latest RHEL except that it’s about one week ahead of RHEL.
However, if you are contemplating installing a new development system, then use RHEL 8.0 since it is now free with a subscription for up to 16 Servers using a Red Hat Developers account (also freely accessible!).
