Centos7：Failed to start LSB: Bring up/down networking

一开始配置的ifcfg-ens33

[root@cdh- ~]# cd /etc/sysconfig/network-scripts/
[root@cdh- network-scripts]# ls
ifcfg-ens33  ifdown-post      ifup-aliases  ifup-post      inactive
ifcfg-lo     ifdown-ppp       ifup-bnep     ifup-ppp       init.ipv6-global
ifdown       ifdown-routes    ifup-eth      ifup-routes    network-functions
ifdown-bnep  ifdown-sit       ifup-ippp     ifup-sit       network-functions-ipv6
ifdown-eth   ifdown-Team      ifup-ipv6     ifup-Team
ifdown-ippp  ifdown-TeamPort  ifup-isdn     ifup-TeamPort
ifdown-ipv6  ifdown-tunnel    ifup-plip     ifup-tunnel
ifdown-isdn  ifup             ifup-plusb    ifup-wireless

IPV6_PEERDNS=yes
IPV6_PEERROUTES=yes

问题状态：

执行 service network restart 出现以下错误

Restarting network (via systemctl):  Job for network.service failed. See 'systemctl status network.service' and 'journalctl -xn' for details.

执行systemctl status network:

显示有标题的错误信息。《Failed to start LSB: Bring up/down networking.》 原因是mac地址的问题

执行ip addr显示以下ip列表：

解决方案：

修改ifcfg-ens33文件了，只修改HWADDR就可以了。接下来执行service network restart 就正常了。

修改后ifcfg-ens33

[root@cdh- network-scripts]# more ifcfg-ens33
TYPE=Ethernet
PROXY_METHOD=none
BROWSER_ONLY=no
BOOTPROTO=static
DEFROUTE=yes
IPV4_FAILURE_FATAL=no

HWADDR=00:0c:29:93:9e:97

ONBOOT=yes

 备注：HWADDR配置的地址是我自己电脑ip addr显示的地址，你需要配置自己的地址。
