If you have some DBaaS computes nodes in your OCI, you will note that they don't come with any YUM repo configured by default. This is purposely architect to avoid you from installing or messing the system that you should be using "As a Service".
[root@erptest04db ~]# yum install telnet
Loaded plugins: versionlock
There are no enabled repos.
Run "yum repolist all" to see the repos you have.
To enable custom repositories:
yum-config-manager --enable <repo>
[root@erptest04db ~]#
However, sometimes I need some flexibility to add some custom yum packages.
To do it, let's simply download the latest ol6 / ol7 / ol8 repo file to the yum folder as root.
First check your OS version.
[root@erptest04db ~]# cat /etc/redhat-release
Red Hat Enterprise Linux Server release 7.8 (Maipo)
[root@erptest04db ~]#
Now download the yum repo and the version lock file for your OS version.
Please note the versionlock file may be already present, so it's not recommended to replace it.
