Centos重啟網卡失敗原因

標籤：interface   network   網卡   

準備重啟網卡，用了兩條命令都沒能成功

[[email protected] Desktop]# ifup eth0
Active connection state: activating
Active connection path: /org/freedesktop/NetworkManager/ActiveConnection/1
^C** Message: Caught signal 2, shutting down...
[[email protected] Desktop]# /etc/init.d/network restart
Shutting down interface eth0:  Device state: 3 (disconnected)
                                                           [  OK  ]
Shutting down loopback interface:                          [  OK  ]
Bringing up loopback interface:                            [  OK  ]
Bringing up interface eth0:  Active connection state: activating
Active connection path: /org/freedesktop/NetworkManager/ActiveConnection/2
state: activated
注意到兩次的報錯都是相同的一句話

Active connection path: /org/freedesktop/NetworkManager/ActiveConnection/

百度找尋解決辦法，得到如下答案

通過網路管理工具修改IP之後，當前修改操作是不會生效的。那如何消除這個提示呢？

其實，問題的原因是RedHat自己開發的NetworkManager管理工具和/etc/sysconfig/network-scripts/ifcfg-ethx配置不同步造成的。如果要消除這個提示，請關閉NetworkManager服務即可：

[[email protected] dev]# chkconfig NetworkManager off  ----

只需要取消一個服務就可以了

[[email protected] Desktop]# service NetworkManager stop
Stopping NetworkManager daemon:                            [  OK  ]
接下來繼續之前的步驟就可以了

[[email protected] Desktop]# /etc/init.d/network restart
Shutting down interface eth0:                              [  OK  ]
Shutting down loopback interface:                          [  OK  ]
Bringing up loopback interface:                            [  OK  ]
Bringing up interface eth0: 
Determining IP information for eth0... done.
                                                           [  OK  ]
