How to activate CentOS 6 ELS with an activation key?

Environment

•  CentOS 6 ELS

Solution

1- To enable the CentOS 6 ELS repository on a server, follow these steps:

Disable the original centos 6 repos:

yum-config-manager --disable base 
yum-config-manager --disable extras 
yum-config-manager --disable updates

2- Download an installer script:

wget https://repo.cloudlinux.com/centos6-els/install-centos6-els-repo.sh

3- Run the installer script with keys:

sh install-centos6-els-repo.sh --license-key XXXX-XXXXXXXXX

The installation script registers a server in CLN with the key and adds a PGP key to the server.

4- Verify that the installation was successful.

To ensure the installation has been completed successfully, run the following command:

yum info els-define

It should return the info about an available package. If you can see information about the package, you can be sure that the installation was successful. After this, you will be able to install updates from the repository using a regular yum upgrade command.

Example:

[els@centos6 ~]# yum info els-define
