配置：
##nmcli con add type wifi ifname [网卡名称] con-name [自定义名字 最好和SSID一致] ssid [WIFI-SSID]
# nmcli con add type wifi ifname wlx40a5ef24e92f con-name iWorld-AX ssid iWorld-AX
# nmcli con edit id iWorld-AX
nmcli> set wifi-sec.key-mgmt wpa-eap //设置安全类型，“wpa-eap”为WPA2企业
nmcli> set ipv4.method auto
nmcli> set 802-1x.eap peap //设置认证方式，PEAP版本为“自动”
nmcli> set 802-1x.phase2-auth mschapv2 //设置内部认证
nmcli> set 802-1x.identity ewsim //Username
nmcli> set 802-1x.password Polling002 //password
nmcli> save
nmcli> activate
设置开机连接
**nmcli connection modify IFNAME connection.autoconnect yes**
root@mtr2:~# nmcli connection modify iWorld-AX connection.autoconnect yes
设置静态IP
- 设置固定 IP 地址：使用
**nmcli connection modify**命令来修改连接配置，将其设置为固定 IP 地址。 - 例如，假设你要将接口名称为 eth0 的连接设置为固定 IP 地址为 192.168.1.100，网关为 192.168.1.1，DNS 服务器为 8.8.8.8，你可以执行以下命令：
**sudo nmcli connection modify eth0 ipv4.addresses 192.168.1.100/24 ipv4.gateway 192.168.1.1 ipv4.dns 8.8.8.8 ipv4.method manual**- 确保将命令中的 eth0 替换为你要设置的网络接口名称，以及将 IP 地址、网关和 DNS 服务器替换为你的实际配置。
- 重新启用连接：执行以下命令重新启用网络连接，使修改生效：
**sudo nmcli connection up eth0**
server1:
sudo nmcli connection modify iWorld-AX ipv4.addresses 192.168.227.27/18 ipv4.gateway 192.168.244.1 ipv4.dns 8.8.8.8 ipv4.method manual
server2:
sudo nmcli connection modify iWorld-AX ipv4.addresses 192.168.228.75/18 ipv4.gateway 192.168.244.1 ipv4.dns 8.8.8.8 ipv4.method manual
sudo nmcli connection up iWorld-AX
