Failed to start LSB: Bring up/down networking

遇到这个错误好几次,所以总结了一下排解的几种方法。

错误记录及排查方法过程:

当我克隆出一台新的centos7的虚拟机的时候,修改了网卡配置文件启动时,报错

[root@centos7 ~]#

按照提示输入systemctl status network.service查看

无奈去百度了一下,找到解决方法,说是centos7没有70-persistent-net.rules这个文件,所以新克隆的机器需要配置mac地址。

通过ip a命令查看mac地址是00:0c:29:0c:15:49

1
2
2: eno16777736: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000
    link/ether 00:0c:29:0c:15:49 brd ff:ff:ff:ff:ff:ff

然后在配置文件中加入这一行(如果存在的话只修改就可以)

1
HWADDR=00:0c:29:0c:15:49

重启生效

发现无法加载/etc/sysconfig/network-scripts/ifcfg-lo文件

给NetworkManager-wait-online服务设置开机自启动

1
systemctl enable NetworkManager-wait-online.service

然后重启网卡

查看日志

这个错误依然存在

将 NetworkManager关闭,然后重启网卡,查看日志

[root@centos7 ~]#

依然是这个错误,然后我又重新百度,说虚拟机设置中的两个连接选项(已连接和启动时连接)没有选择也会报同样的错,但是我的已经连接,问题依然存在,到底是因为什么呢?再次查找方法。

结果这次认真看了日志报错后发现是说eth0这个文件找不到

Mar 14 00:36:39 centos7 network: Bringing up interface eth0:  ERROR    : [/etc/sysconfig/network-scripts/ifup-eth] Device eth0 does not seem to be present, delaying initialization.
Mar 14 00:36:39 centos7 /etc/sysconfig/network-scripts/ifup-eth: Device eth0 does not seem to be present, delaying initialization.

原来是之前做优化的时候将7的网卡名改成了eth0(众所周知7的网卡名是eno后面随机 一串数字),生成菜单时没有生效,那么在此生效一下

注意网卡配置名是已经修改成eth0以后执行下面操作,一共修改的地方有三处,第一处网卡名:/etc/sysconfig/network-scripts/ifcfg-eth0 ,第二处配置文件里面:NAME=eth0 ,第三处也是配置文件里面:DEVICE=eth0

修改/etc/sysconfig/grub,添加net.ifnames=0 biosdevname=0

最后登录后正常
