Linux 下重启网卡报 disconnecting failed: This device is not active错误

今天修改IP地址执行  service network restart

出现以下错误：

[root@localhost Desktop]# service network restart
Shutting down interface eth0: Error: Device \'eth0\' (/org/freedesktop/NetworkManager/Devices/0) disconnecting failed: This device is not active
                                                           [FAILED]
Shutting down loopback interface: [ OK ]
Bringing up loopback interface: [ OK ]
Bringing up interface eth0: Error: Connection activation failed: Device not managed by NetworkManager or unavailable

 原因：NetworkManager 与network两个服务冲突导致。

解决办法： 关闭NetworkManager 服务

[root@localhost Desktop]# chkconfig NetworkManager off  
[root@localhost Desktop]# chkconfig network on
[root@localhost Desktop]# service NetworkManager stop
Stopping NetworkManager daemon: [ OK ]
[root@localhost Desktop]# service network restart
Shutting down interface eth0: [ OK ]
Shutting down loopback interface: [ OK ]
Bringing up loopback interface: [ OK ]
Bringing up interface eth0: [ OK ]

 chkconfig NetworkManager off 永久关闭NetworkManager服务不会立即生效

service NetworkManager stop 立即关闭，如果为chkconfig系统重启后会重新打开

chkconfig network on 永久性启动（不会立即生效）

service network start 立即启动（启动newwork服务）

service network restart：重启newwok服务
