The YUM Repository Config predefined task is a script used for updating the YUM repositories to install or update software on CentOS or other RPM-based operating systems.

About this task

You can configure the YUM Repository Config properties to add a new repository or remove all of the existing repositories. If you need more than one repository, you can create multiple tasks and link them in the execution plan by adding one task next to the other.

Use the predefined sample task only in a test environment.


  • Log in to Application Services with a user account that has an Application Services role assigned to it.

  • Verify that the predefined task is added to the execution deployment plan before you add any services or application components that require YUM for installing or updating software packages.

  • Verify that Application Services is configured to use a proxy. See Configure Application Services to Use a Proxy for External URLs.
