最小安装下，默认是没有办法运行X客户端程序的。需要安装"X Window System"和"Fonts"这两个组包.
yum -y group install "X Window System"
yum -y group install "Fonts"
yum -y install nm-connection-editor这样在安装完所有依赖以后就能顺利显示NM-gui配置器啦！！
FYI: 组包check
yum group list hidden | grep X
....
yum group list hidden | grep Font
....
yum group list env | grep Minimal
