centos7系统重启网卡失败
时间:2020-03-17 10:49
问题: 执行service network restart命令后出现下面的错误: Restarting network (via systemctl): Job for network.service failed because the control process exited with error code. See "systemctl status network.service" and "journalctl -xe" for details. [失败] (推荐教程:centos使用教程) 解决方法: 1、.和 NetworkManager 服务有冲突,直接关闭 NetworkManger 服务就好了, service NetworkManager stop,并且禁止开机启动 chkconfig NetworkManager off 。之后重启就好了。 2、和配置文件的MAC地址不匹配,这个也好解决,使用ip addr(或ifconfig)查看mac地址 00:0c:29:5f:9e:1d这个就是MAC地址了,将/etc/sysconfig/network-scripts/ifcfg-xxx中的HWADDR(如果没有就添加上)改成这个MAC地址。 3、设定开机启动一个名为NetworkManager-wait-online服务,命令为: 4、查看/etc/sysconfig/network-scripts下,将其余无关的网卡位置文件全删掉,避免不必要的影响,即只留一个以ifcfg开头的文件 5、将ifcfg-xxx文件中的DEVICE一行注释掉。 6、将ifcfg-xxx中的NAME改为和文件名一致。 相关视频教程分享:linux视频教程 以上就是centos7系统重启网卡失败的详细内容,更多请关注gxlcms其它相关文章![root@royfans royfans]# ip a
