请看红色部门failedtostartlsb : bring up/down networking。但是，实际上这个信息很少用于鸡蛋

我相信如果你不带着这个信息在网上搜索，你可能会失望而归。 cdn等博客都是你抄我，我抄你，从来没有验证过的是复制粘贴。

调查想法

遇到这样的问题，最好的办法就是看看日志输出了什么。运行tail-f/var/log/messages

[根@ ceph0~ ] # tail-f/var/log/messages|grep network

mar 2612336005336006 ceph0systemd : starting LSB : bring up/down networking .

mar 2612336005336006 ceph 0net work : bringinguploopbackinterface : [ ok ]

mar 2612336005336006 ceph0systemd : unit network.serviceenteredfailedstate。

mar 2612336005336006 ceph0systemd : network.service failed。

出现误报

mar 2612336005336006 ceph 0net work : bringingupinterfaceeth 1: error : connectionactivationfailed : nosuitabledeviceviecefououre

mar 2612336005336006 ceph 0net work : [ failed ]

mar 2612336005336006 ceph 0net work : bringingupinterfaceeth 2: error : connectionactivationfailed : nosuitabledeviceviecefououre

很明显，如果没有eth1和eth2连接器，将出现错误，/etc/sys config/network-scripts /

删除eth1和eth2配置文件，然后重新启动网卡即可
