Sometimes CloudLinux will first release packages to their testing repositories before releasing them to the stable repositories. If you need a package that has not been released to stable, this is how you would install the needed package.
It's not advisable to enable the repositories globally on a production server. If these packages are needed, the repository will need to be enabled during the yum transaction.
Yum has the enable-repo flag that enables the repository only for the command being run.
yum update $PACKAGENAME --enablerepo=cloudlinux-updates-testing
$PACKAGENAME will be the name of the package you are updating.
Locating Other Testing Repositories
If the cloudlinux-updates-testing repository does not contain the package that you're looking for, you may consider reviewing the other disabled repositories to see if they may contain the package.
It is critical to keep in mind that these testing repositories are not intended to be used on production servers. Making use of these repositories or the software within the repositories may cause unexpected and unsupported problems. Please proceed with caution and the understanding that problems introduced by making use of these testing software would need to be resolved by a systems administrator.
You may use the following command to see a list of the disabled repositories on your server which would include the testing repositories:
yum repolist disabled
If you're looking for testing or experimental software that should not be used on a production server, the repository name will typically include the word "experimental" or "testing".
Listing Packages Available From Testing Repositories
Once you have found the repository that you think may contain the software that you are looking for with the above described method, you may search the repository for your desired package with the following command:
yum list available --enablerepo="cloudlinux-updates-testing" --disablerepo="*"
If you want to check for updates for packages that you already have installed you would use this command:
yum check-update --enablerepo="cloudlinux-updates-testing"
