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
[root@royfans royfans]# ip a 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN qlen 1 link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo valid_lft forever preferred_lft forever inet6 ::1/128 scope host valid_lft forever preferred_lft forever 2: ens33: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN qlen 1000 link/ether 00:0c:29:5f:9e:1d brd ff:ff:ff:ff:ff:ff 3: virbr0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc noqueue state DOWN qlen 1000 link/ether 52:54:00:67:8e:c3 brd ff:ff:ff:ff:ff:ff inet 192.168.122.1/24 brd 192.168.122.255 scope global virbr0 valid_lft forever preferred_lft forever 4: virbr0-nic: <BROADCAST,MULTICAST> mtu 1500 qdisc pfifo_fast master virbr0 state DOWN qlen 1000 link/ether 52:54:00:67:8e:c3 brd ff:ff:ff:ff:ff:ff
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:
systemctl enable NetworkManager-wait-online.service
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。
