Server Configuration 101

Configuration Management is about maintaining servers in a desired state by installing and removing software, and providing up-to-date configuration files. It's is a better part of this book, because we have to set up and configure every corner of the system. To start, we'll learn about managing system software and how to automate it.When we provision a Linux server, we notice it doesn't come empty. There is a lot of software already pre-installed, some with configuration files in the /etc directory. This software came in the form of packages and can be further managed by a system package manager. In the Fedora family, packages follow the RPM format and are managed by DNF.
