问题描述：
安装虚拟机器-->安装centos7 x64,使用MobaXterm_Personal_23.2.exe 连接centos,
报错如下图：
Job for network.service failed because the control process exited with error code. See "systemctl status network.service" and "journalctl -xe" for details.
根据错误描述，网上搜索寻找解决方案，
1.检查网络状态 systemctl status network.service
2.systemctl stop NetworkManager 关闭网络管理
systemctl disable NetworkManager
systemctl start network.service 然后重启网络
之后还是之前的错误，
ip addr
cat /etc/sysconfig/network-scripts/ifcfg-ens33
vim /etc/sysconfig/network-scripts/ifcfg-ens33
把动态改为静态，增加ip网络显式设置，
因为是把之前虚拟机的DHCP复选框对勾去掉了。
