Manually configuring the MySQL repository
If the system on which you are installing Unified Manager does not have access to the MySQL Community Edition repository, then you must manually download and configure the repository for a successful installation.

This task might fail if the system does not have Internet connectivity. Refer to the MySQL documentation if the system on which you are installing Unified Manager does not have Internet access.

Configure the MySQL repository:
yum install mysql80-community-release-<version>.noarch.rpm

On a system that does not have internet connectivity, update your MySQL repo file and disable
