Linux查看网卡UUID的方法

阅读更多

1、首先我们查看一下nmcli是哪个软件包提供的

 

1 2 3 4 5 6 7 8 9 10 11

[ 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

 

1 2 3

[ root @ huis ~ ] # service NetworkManager start Setting network parameters . . .                        [    OK    ] Starting NetworkManager daemon :                      [    OK    ]

4、查看网卡UUID

 

1 2 3

[ 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     Mon 08 Dec 2014 12 : 49 : 14 PM 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）

 

1 2	[ root @ huis ~ ] # cat /etc/sysconfig/network-scripts/ifcfg-eth0 | grep UUID UUID = c1021d28 - 7238 - 4f26 - 8e92 - 4aea5d607cab
