Yum Update for Oracle Linux 7 and Oracle Linux 8 Instances
The yum configuration has changed in Oracle Cloud Infrastructure for yum mirror endpoints.
No action is required for new Oracle Linux 7 and Oracle Linux 8 instances launched in Oracle Cloud Infrastructure after March 2021, as the changes are automatically applied. Although existing yum configurations continue to work in older instances, it is recommended that you update your instances to the new yum configuration.
Follow these steps to configure your Oracle Linux 7 and Oracle Linux 8 instances to use the updated configuration.
Determine the Oracle Cloud Infrastructure realm where the image is running:
curl -H "Authorization:Bearer Oracle" -sfm 25 \ http://169.254.169.254/opc/v2/instance/ 2>/dev/null | jq -r '.regionInfo.realmKey'
Notice the realm key displayed in the output. If the output displays a realm key from OC1 to OC4, proceed to the next step.
$ curl -H "Authorization:Bearer Oracle" -sfm 25 \ http://169.254.169.254/opc/v2/instance/ 2>/dev/null | jq -r '.regionInfo.realmKey' oc1
sudo yum -y install oci-linux-config
During the installation of this package, the following message is displayed:
IMPORTANT: PLEASE NOTE!! Oracle Linux yum repository configurations have been updated. New repository configuration files have been installed but are disabled. To complete the transition, run this script as root user:/usr/lib/oci-linux-config/oci_yum_configure.sh
Invoke the script to complete the transition to the new mirror endpoints:
Verify that the yum configuration has been updated:
