[root@localhost ~]# yum -y groups mark install 'Development Tools' #如果你安装虚拟机时，安装过开发工具，此步骤无需操作
Loaded plugins: product-id, search-disabled-repos, subscription-manager
This system is not registered with an entitlement server. You can use subscription-manager to register.
There is no installed groups file.
Maybe run: yum groups mark convert (see man yum)
Marked install: Development Tools
