1. Check the card information ifconfig
2. Modify the NIC configuration file
vim vi /etc/sysconfig/network-scripts/ifcfg-ens33
修改或添加了 标*

You can see, BOOTPROTO as a dhcp , dynamic allocation of IP addresses, now take it into static
at the same time, you need to set the IP address, gateway, subnet mask, DNS
The final card configuration information is as follows
Check ifconfig again
3. Network Service Restart
systemctl restart network
