• CentOS中Device eth0 does not seem to be present错误解决办法


    今天克隆的虚拟机,当需要多台虚拟机的时候,试用克隆真是方便,不过遇到了
    Device eth0 does not seem to be present 的问题,在网上找到遇到同样问题的解决方法,
    很顺利的解决,记录之:

    ifconfig…没有看到eth0.。然后重启网卡又报下面错误。

    故障现象:

    service network restart
    Shutting down loopback insterface: [ OK ]
    Bringing up loopback insterface: [ OK ]
    Bringing up interface eth0: Device eth0 does not seem to be present,delaying initialization. [FAILED]

    CentOS Linux解决Device eth0 does not seem to be present

    解决办法:
     
     
    首先,打开/etc/udev/rules.d/70-persistent-net.rules内容如下面例子所示:

    # vim /etc/udev/rules.d/70-persistent-net.rules
    # This file was automatically generated by the /lib/udev/write_net_rules
    # program, run by the persistent-net-generator.rules rules file.
    #
    # You can modify it, as long as you keep each rule on a single
    # line, and change only the value of the NAME= key.
    # PCI device 0×1022:0×2000 (pcnet32)
    SUBSYSTEM==”net”, ACTION==”add”, DRIVERS==”?*”, ATTR{address}==”08:00:27:7e:8c:e7″, ATTR{type}==”1″, KERNEL==”eth*”, NAME=”eth0″
    # PCI device 0×1022:0×2000 (pcnet32)
    SUBSYSTEM==”net”, ACTION==”add”, DRIVERS==”?*”, ATTR{address}==”08:00:27:30:c2:57″, ATTR{type}==”1″, KERNEL==”eth*”, NAME=”eth1″

    记录下,eth1网卡的mac地址08:00:27:30:c2:57

    接下来,打开/etc/sysconfig/network-scripts/ifcfg-eth0

    # vim /etc/sysconfig/network-scripts/ifcfg-eth0

    将 DEVICE=”eth0″ 改成 DEVICE=”eth1″ ,
    将 HWADDR=”08:00:27:7e:8c:e7″ 改成上面的mac地址 HWADDR=”08:00:27:30:c2:57″

    这里需要用到vim的复制y  粘贴p

    如果当前正处于编辑模式,需要先按下ESC键,再按下键盘上的ctrl+v键(一般状态只需要按下 ctrl+v),此时编辑框内的最下方将出现“可视 块”的提示字样。

    使用方向键移动光标,选择矩形区域内的文字。

    按下 y 键,复制所选文本。

    用方向键移动光标到需要粘贴的位置处,再按下 p 键粘贴。

    最后,重启网络

    # service network restart
    或者

    # /etc/init.d/network restart

    正常了,搞定
