重新加载网卡时出现的错误如下：

 1 [root@vdb1 dev]# service network restart
 2 Shutting down interface eth0:  Device state: 3 (disconnected)
 3                                                            [  OK  ]
 4 Shutting down interface eth1:                              [  OK  ]
 5 Shutting down interface eth2:  Device state: 3 (disconnected)
 6                                                            [  OK  ]
 7 Shutting down loopback interface:                          [  OK  ]
 8 Bringing up loopback interface:                            [  OK  ]
 9 Bringing up interface eth0:  Active connection state: activating
10 Active connection path: /org/freedesktop/NetworkManager/ActiveConnection/23

13 Bringing up interface eth1:  Active connection state: activated
14 Active connection path: /org/freedesktop/NetworkManager/ActiveConnection/25
15                                                            [  OK  ]
16 Bringing up interface eth2:  Active connection state: activated
17 Active connection path: /org/freedesktop/NetworkManager/ActiveConnection/26
18                                                            [  OK  ]

此时，当前网卡也是可以通信的，但是通过网络管理工具修改IP之后，当前修改操作是不会生效的。那如何消除这个提示呢？

其实，问题的原因是RedHat自己开发的NetworkManager管理工具和/etc/sysconfig/network-scripts/ifcfg-ethx配置不同步造成的。如果要消除这个提示，请关闭NetworkManager服务即可：

[root@vdb1 dev]# chkconfig NetworkManager off  --永久关闭服务，需要重启
[root@vdb1 dev]# service NetworkManager stop   --立即关闭服务，不需要重启
Stopping NetworkManager daemon:                            [  OK  ]

此时，再重新加载network服务即可：

 1 [root@vdb1 dev]# service network restart
