优点:
高可用,负载均衡
实验环境:
Centos:
-------------ens32
-------------ens33
[root@localhost ~]# rm -rf /etc/sysconfig/network-scripts/ifcfg-ens* #删除原有网卡配置文件
[root@localhost ~]# nmcli device status #查看设备状态
[root@localhost ~]# systemctl restart network
[root@localhost ~]# nmcli connection add type team con-name team0 ifname team0 config '{"runner":{"name":"activebackup"}}' #创建链路聚合
[root@localhost ~]# nmcli connection show #查看网卡状态
[root@localhost ~]# nmcli connection add type team-slave con-name team0-1 ifname ens32 master team0
[root@localhost ~]# nmcli connection add type team-slave con-name team0-2 ifname ens33 master team0
[root@localhost ~]# nmcli device status
[root@localhost ~]# teamdctl team0 state #查看team0链路状态
[root@localhost ~]# nmcli connection up team0-1 #开启team0-1
[root@localhost ~]# nmcli connection up team0-2 #开启team0-2
[root@localhost ~]# vim /etc/sysconfig/network-scripts/ifcfg-team0
###添加IP等网卡信息###
###或者用nmcli connection modify team0 ipv4.addresses 192.168.3.200/24 ipv4.gateway 192.168.3.254 ipv4.method manual
[root@localhost ~]# nmcli connection up team0 #开启team0
######之后断开其中一块网卡模拟故障(vmwear虚拟机需要重启网卡)
