What should I do if the centos system fails to restart the network?

Environment: centos7 system

Problem description:

[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 one HWADDR

Enter ip addr, find HWADDR

and enter cd /etc/sysconfig/network-scripts Edit the corresponding vim ifcfg-ensXX, set the HWADDR correctly, and restart

service network restart

If it still doesn’t work, you need to reset the IP.
