redhat7linux双网卡绑定,RHEL7/RHEL8/CentOS7/CentOS8/双网卡绑定-Network bonding
一,创建bonding
创建名称为bond1的绑定
[root@localhost ~]# nmcli con add type bond con-name bond1 ifname bond1 mode active-backup
Connection ‘bond1’ (74659382-3e46-4a95-851d-66f90b2ece30) successfully added.
将enp7s0f0增加到bond1
[root@localhost ~]# nmcli connection add type bond-slave ifname enp7s0f0 master bond1
Connection ‘bond-slave-enp7s0f0’ (061f5c5c-3366-4025-8149-7c89e49ab1b3) successfully added.
将enp7s0f1增加到bond1
[root@localhost ~]# nmcli connection add type bond-slave ifname enp7s0f1 master bond1
Connection ‘bond-slave-enp7s0f1’ (45440593-243e-4618-ab1a-0845555e11c1) successfully added.
二,启动bonging
启动从属接口enp7s0f0
[root@localhost ~]# nmcli connection up bond-slave-enp7s0f0
Connection successfully activated (D-Bus active path: /org/freedesktop/NetworkManager/ActiveConnection/6)
启动从属接口enp7s0f1
[root@localhost ~]# nmcli connection up bond-slave-enp7s0f1
Connection successfully activated (D-Bus active path: /org/freedesktop/NetworkManager/ActiveConnection/7)
启动绑定
[root@localhost ~]# nmcli connection up bond1
Connection successfully activated (master waiting for slaves) (D-Bus active path: /org/freedesktop/NetworkManager/ActiveConnection/11)
[root@localhost ~]# ifconfig
bond1: flags=5123 mtu 1500
