如何添加网卡做bond5聚合？

Posted 2020-12-04

1.添加2块网卡做bond5聚合
不要在图形界面做，会出网卡自配IP，无法使用聚合

2.查询，配置虚拟网卡 ，根据自己的网关配置虚拟网关和dns，ip自定义
[[email protected] ~]# nmcli dev

[[email protected] ~]# nmcli connection add type bond mode balance-tlb con-name bond5 ifname bond5 ipv4.method manual ipv4.addresses 192.168.56.12/24 ipv4.gateway 192.168.56.2 ipv4.dns 192.168.56.2

连接“bond5”(e6039f16-d78e-4fdd-82ca-b4490a40d9d3) 已成功添加。
[[email protected] ~]# nmcli dev
设备 类型 状态 连接
bond5 bond 连接的 bond5

3.将物理网卡连接至bond5
[[email protected] ~]# nmcli connection add type bond-slave con-name bond5-slave0 ifname ens38 master bond5
[[email protected] ~]# nmcli connection add type bond-slave con-name bond5-slave1 ifname ens39 master bond5
连接“bond5-slave0”(5e15186b-4fc9-450d-9095-bcbc553812ad) 已成功添加。

4.查看bond信息
[[email protected] ~]# cat /proc/net/bonding/bond5

[[email protected] ~]# ping 192.168.56.12

断开
[[email protected] ~]# nmcli device disconnect ens38

[[email protected] ~]# ping 192.168.56.12 当可ping通

激活
[[email protected] ~]# nmcli device connect ens38

成功用 ‘ens38‘ 激活了设备 ‘5e15186b-4fc9-450d-9095-bcbc553812ad‘。
