How to set up the Oracle Yum Repository for RHEL 8 (Red Hat Enterprise Linux 8)

Steps:

1) Create a temporary file for repository for OEL8

[root@ocicliserver ~]# cd /etc/yum.repos.d/

[root@ocicliserver yum.repos.d]#

vi public-yum-ol8.repo

[foa_ol8_baseos_latest]

name=Oracle Linux 8 BaseOS Latest ($basearch)

baseurl=https://yum.oracle.com/repo/OracleLinux/OL8/baseos/latest/$basearch/

gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-oracle

gpgcheck=1

enabled=1

2) Download Oracle Linux 8 GPG Key

To prevent GPG key retrieval failed, we need to download the right GPG key for the above Oracle yum repository.

[root@ocicliserver yum.repos.d]# wget https://yum.oracle.com/RPM-GPG-KEY-oracle-ol8 -O /etc/pki/rpm-gpg/RPM-GPG-KEY-oracle

3) Install oraclelinux-release-el8:

# dnf install oraclelinux-release-el8

4) Remove public-yum-ol8.repo (done in step1) and any other remaining repo files that may conflict with Oracle Linux yum server:

# mv /etc/yum.repos.d/public-yum-ol8.repo /etc/yum.repos.d/public-yum-ol8.repo.disabled

5) Validate new repositories. I will validate the EBS package.

[root@ocicliserver yum.repos.d]# dnf info oracle-ebs-server-R12-preinstall
