For example, to install a game program group, first perform the following operations:
#: Yum grouplist
It can be found that the installable game package name is "Games and Entertainment", so that you can install it:
#: Yum groupinstall "Games and Entertainment"
All game packages are automatically installed. Here, the names of Games and Entertainment must be selected in double quotation marks, because the names of Games and Entertainment are ended when spaces are encountered in linux, therefore, you must tell the system to install the package named "Games and Entertainment" instead of "Games ".
You can also modify the configuration file/etc/yum. conf to select the installation source. It can be seen that the configuration program of yum is easy for many parties. For more detailed options and commands, you only need to follow the command prompt line below: man yum
