centos8搭建网桥

1. nmcli命令搭建

nmcli connection add type bridge con-name br0 ifname br0 autoconnect yes
nmcli connection modify br0 ipv4.addresses "192.168.8.16/24" ipv4.gateway 192.168.8.1 ipv4.dns 8.8.8.8 ipv4.method manual connection.autoconnect yes
nmcli connection add type bridge-slave ifname enp8s0f0 master br0


nmcli connection down enp8s0f0; nmcli connection up br0
nmcli connection show

 

2. 配置文件搭建
