  • Linux 虚拟机重新生成配置文件无法启动

    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:

    # vi /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 0x1022:0x2000 (pcnet32)
    SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:0c:29:8f:89:9
    7", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0"
    # PCI device 0x1022:0x2000 (pcnet32)
    SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:0c:29:50:bd:1
    7", ATTR{type}=="1", KERNEL=="eth*", NAME="eth1"

    记录下,eth1网卡的mac地址00:0c:29:50:bd:17

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

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

    将 DEVICE="eth0"  改成  DEVICE="eth1"  ,
    将 HWADDR="00:0c:29:8f:89:97" 改成上面的mac地址  HWADDR="00:0c:29:50:bd:17"

    最后,重启网络

    # service network restart
    或者

    # /etc/init.d/network restart

    正常了。
