1.场景描述，我在电脑里装好的虚拟机，今天突然就网络无法打开，并出现如下报错：

[root@ansible-control ~]# systemctl start network
Job for network.service failed because the control process exited with error code. See "systemctl status network.service" and "journalctl -xe" for details.
[root@ansible-control ~]# systemctl status network

2.解决方法

　　关闭NetworkManager，罪魁祸首就是这个服务！

第一步：查看NetworkManager服务状态：

systemctl status network.service,服务器,linux

第二步：关闭NetworkManager，并设置开启默认不启动该服务：

[root@ansible-control ~]# systemctl stop NetworkManager

[root@ansible-control ~]# systemctl disable NetworkManager

Removed symlink /etc/systemd/system/multi-user.target.wants/NetworkManager.service.

Removed symlink /etc/systemd/system/dbus-org.freedesktop.NetworkManager.service.

Removed symlink /etc/systemd/system/dbus-org.freedesktop.nm-dispatcher.service.

第三步：重启network服务

[root@ansible-control ~]# systemctl status network.service

● network.service - LSB: Bring up/down networking

Loaded: loaded (/etc/rc.d/init.d/network; bad; vendor preset: disabled)

Active: failed (Result: exit-code) since 日 2019-09-29 22:53:32 CST; 9s ago

Docs: man:systemd-sysv-generator(8)

Process: 3620 ExecStart=/etc/rc.d/init.d/network start (code=exited, status=1/FAILURE)

　　发现还是报错，此时，我又百度了其它方法尝试，发现是MAC地址的问题，参考一篇文章：https://www.raksmart.com/29.html?l=zh-cn

第四步：查询主机的硬件地址：

systemctl status network.service,服务器,linux

第五步：修改/etc/sysconfig/network-scripts/ifcfg-配置_1文件

systemctl status network.service,服务器,linux

第六步：再次重启网络

1 2	`[root@ansible-control ~]# systemctl restart network` `[root@ansible-control ~]# systemctl status network`

systemctl status network.service,服务器,linux

此时已经成功开启网络！文章来源地址https://www.toymoban.com/news/detail-628102.html
