关于CentOS/RHEL 7.x的yum组安装错误的解决方案

今天使用CentOS 7的组安装，结果发现提示错误，

yum groupinstall "System Administration Tools"

详细信息如下：

Loaded plugins: fastestmirror, langpacks
Loading mirror speeds from cached hostfile
* base: mirrors.aliyun.com
* extras: mirrors.aliyun.com
* updates: mirrors.aliyun.com
Warning: Group system-admin-tools does not have any packages to install.
Maybe run: yum groups mark install (see man yum)
No packages in any requested group available to install or update

经过一番谷歌，结果发现红帽的官方说7中的yum已经发生变化，需要使用特定选项来安装，具体命令如下：

yum groupinstall "System Administration Tools" --setopt=group_package_types=mandatory,default,optional
