[root@huis~]# yum provides "*/nmcli"

Loaded plugins：fastestmirror,security

Loading mirror speeds from cached hostfile

 *base:mirrors.cug.edu.cn

 *extras:mirrors.cug.edu.cn

 *updates:centos.ustc.edu.cn

1:NetworkManager-0.8.1-75.el6.i686:Network connection manager and

                                   :user applications

Repo        :base

Matched from:

Filename    :/usr/bin/nmcli

2、从上面结果可以看出nmcli，接下来我们安装NetworkManager这个软件包

 
1

[root@huis~]# yum -y install NetworkManager

3、启动NetworkManager服务

[root@huis~]# service NetworkManager start

[root@huis~]# nmcli con | sed -n '1,2p'

NAME                   UUID                                   TYPE              SCOPE      TIMESTAMP-REAL                   

System eth0            c1021d28-7238-4f26-8e92-4aea5d607cab   802-3-ethernet    system     Mon08Dec201412:49:14PM CST

5、检验是否与/etc/sysconfig/network-scripts/ifcfg-eth0里面的UUID值相同（注：检验只在ifcfg-eth0文件能正常查看UUID时才有效）

[root@huis~]# cat /etc/sysconfig/network-scripts/ifcfg-eth0 | grep UUID

UUID=c1021d28-7238-4f26-8e92-4aea5d607cab
