CentOS 8 ELS

Connection to ELS repository

To install the Endless Lifecycle Support repository on a server, you just need to download an installer script and run the script with a key. The installation script will register the server in the CLN with the key, add a PGP key to the server, and create the ELS repository.

Installation of repositories

Download an installer script:

wget https://repo.cloudlinux.com/centos8.4-els/install-centos8.4-els-repo.sh

Run the installer script with keys:
```
sh install-centos8.4-els-repo.sh --license-key XXXX-XXXXXXXXXXXX
```
The installation script registers the server in the CLN with the key and adds a PGP key to the server.
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 of an available package. If you 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@centos8_5 ~]# yum info els-define
