• 解决报错Failed to start LSB: Bring up/down networking:MAC地址导致


    1.场景描述,我在电脑里装好的虚拟机,今天突然就网络无法打开,并出现如下报错:

    [root@ansible-control ~]# systemctl start network
    Job for network.service failed because the control process exited with error code. See "systemctl status network.service" and "journalctl -xe" for details.
    [root@ansible-control ~]# systemctl status network
    ● network.service - LSB: Bring up/down networking
    Loaded: loaded (/etc/rc.d/init.d/network; bad; vendor preset: disabled)
    Active: failed (Result: exit-code) since 日 2019-09-29 22:44:34 CST; 1s ago
    Docs: man:systemd-sysv-generator(8)
    Process: 5042 ExecStart=/etc/rc.d/init.d/network start (code=exited, status=1/FAILURE)

    2.解决方法

      关闭NetworkManager,罪魁祸首就是这个服务!

    第一步:查看NetworkManager服务状态

     第二步:关闭NetworkManager,并设置开启默认不启动该服务:

    [root@ansible-control ~]# systemctl stop NetworkManager
    [root@ansible-control ~]# systemctl disable NetworkManager
    Removed symlink /etc/systemd/system/multi-user.target.wants/NetworkManager.service.
    Removed symlink /etc/systemd/system/dbus-org.freedesktop.NetworkManager.service.
    Removed symlink /etc/systemd/system/dbus-org.freedesktop.nm-dispatcher.service.
    

    第三步:重启network服务

    [root@ansible-control ~]# systemctl status network.service
    ● network.service - LSB: Bring up/down networking
       Loaded: loaded (/etc/rc.d/init.d/network; bad; vendor preset: disabled)
       Active: failed (Result: exit-code) since 日 2019-09-29 22:53:32 CST; 9s ago
         Docs: man:systemd-sysv-generator(8)
      Process: 3620 ExecStart=/etc/rc.d/init.d/network start (code=exited, status=1/FAILURE)
    

      发现还是报错,此时,我又百度了其它方法尝试,发现是MAC地址的问题,参考一篇文章:https://www.raksmart.com/29.html?l=zh-cn

    第四步:查询主机的硬件地址:

    第五步:修改/etc/sysconfig/network-scripts/ifcfg-配置_1文件

    第六步:再次重启网络

    [root@ansible-control ~]# systemctl restart network
    [root@ansible-control ~]# systemctl status network
    

     此时已经成功开启网络!
