The network cannot be restarted under centos7

Problem:

[root@localhost Desktop]# systemctl start network.service
Job for network.service failed. See 'systemctl status network.service' and 'journalctl -xn' for details.

Solution:

1. HWADDR error, find the correct HWADDR

Enter ip addr, Find HWADDR

Enter the cd /etc/sysconfig/network-scripts directory to edit the corresponding vim ifcfg-ensXX, set HWADDR correctly, and restart service network restart

If it still doesn't work here, you need to reset the IP related settings.

(Recommended tutorial: centos tutorial)

2. IP check and setting

Enter the host cmd command window and enter

ipconfig /all

Enter the centos7 virtual machine cd /etc/sysconfig/network-scripts directory and edit the corresponding vim ifcfg-ensXX

and then close the network :

root@localhost Desktop]# service NetworkManager stop
Redirecting to /bin/systemctl stop  NetworkManager.service

Restart:

[root@localhost Desktop]# service network restart
Restarting network (via systemctl):         [  OK  ]
