4.1. Software that must be uninstalled
Red Hat Linux installs other pre-compiled binaries of programs on your system by default and doesn't give you the choice to uninstall them during the install setup. For this reason, you must uninstall the following software on your system after the installation of your server.We must uninstall them for better security and to make space in our server.
