CentOS9修改网卡配置：

[root@web-74 ~]# cat /etc/NetworkManager/system-connections/ens160.nmconnection 
[connection]
id=ens160
uuid=3df568f3-8dcd-3d18-9c17-d3e256ccbb83
type=ethernet
autoconnect-priority=-999
interface-name=ens160
timestamp=1705335427

[ethernet]

[ipv4]
address1=192.168.8.74/24,192.168.8.2
dns=8.8.8.8
method=manual

[ipv6]

[proxy]
 

配置参考：
