There may be different reasons for this problem , Here are two possible causes and solutions

Solution 1

1 There may be more than one network configuration file , Cause failure
First of all to enter network Configure the folder to view the network configuration file , There can only be one ifcfg-exxx

cd /etc/sysconfig/network-scripts

ll

Multiple network profiles , You need to remove , There is only one configuration file left

Solution 2

1 see ifconfig

ifconfig

You can see the actual dynamic allocation 192.168.207.130 Of IP, And you can see that the configuration file is ens33, It's not in my configuration file 192.168.207.137 This IP, And my profile is eno16777736, Therefore, the file name cannot be changed

2 Change my profile name

cd /etc/sysconfig/network-scripts

ll

3 Change the network profile name

mv ifcfg-eno16777736 ifcfg-ens33

4 Edit file contents

vim ifcfg-ens33

5 Restart network settings two , It must be twice

systemctl restart network
