One of the first tasks that system admins should do when they install a new Linux machine is to make sure they have a reliable repository to get the software they need.
Here, following some sources that I consider essential to obtain RPM packages.
1 – Install both those extra repositories epel and remi:
# yum -y install https://dl.fedoraproject.org/pub/epel/epel-release-latest-8.noarch.rpm # yum -y install https://rpms.remirepo.net/enterprise/remi-release-8.rpm
2 – Install the package responsible for handling the yum configuration and enabling the repositories:
# yum -y install yum-utils # yum config-manager --set-enabled powertools # yum config-manager --set-enabled remi # yum config-manager --set-enabled epel
3 – Now, you can update your Linux:
# yum update
