Linux7配置team聚合链
centos7、redhat7使用teaming实现聚合链路，能够提升网卡绑定之后的网络吞吐性能，并且提供网卡故障后切换网卡处理的能力
team是基于小型内核驱动实现聚合链路，在用户层提供teamd命令实现链路管理
teamd可以实现以下模式的聚合链路
broadcast 广播容错
roundrobin 负载轮询
activebackup 主备
loadbalance 负载均衡
lacp 需要交换机支持lacp协议
- 主备模式
1. 添加一个team0 生成绑定网卡team0以及team0的配置文件
nmcli connection add type team con-name team0 ifname team0 config '{"runner":{"name":"activebackup"}}'
2. 修改team0的配置
[root@localhost ~]# nmcli connection modify ipv4.addresses 192.168.1.7/24 ipv4.gateway 8.8.8.8 ipv4.dns 8.8.8.8 ipv4.method manual
3.ping下刚才加的team0
[root@localhost ~]# ping 192.168.1.7
PING 192.168.1.7 (192.168.1.7) 56(84) bytes of data.
64 bytes from 192.168.1.7: icmp_seq=1 ttl=64 time=0.142 ms
...
4. 查看team的状态
[root@localhost ~]# teamdctl team0 state
setup:
runner: activebackup
runner:
active port:
[root@localhost ~]#
5. 将网卡eno16777736绑定到team0上
[root@localhost ~]# nmcli connection add type team-slave con-name team0-port1 ifname eno16777736 master team0
Connection 'team0-port1' (afd6ff8c-6301-4140-af5f-6ca509136ae5) successfully added.
[root@localhost ~]#
6.同理，第二块网卡也是如此：
[root@localhost ~]# nmcli connection add type team-slave con-name team0-port2 ifname ens38 master team0
Connection 'team0-port2' (d0b22519-dbe6-4080-bf25-62eb0da7eacb) successfully added.
[root@localhost ~]#
7.现在team0链路上有互为主备的的网卡了
[root@localhost ~]# teamdctl team0 state
setup:
runner: activebackup
ports:
eno16777736
link watches:
link summary: up
instance[link_watch_0]:
name: ethtool
link: up
down count: 0
ens38
link watches:
link summary: up
instance[link_watch_0]:
name: ethtool
link: up
down count: 0
runner:
active port: ens38
[root@localhost ~]#
//连接和设备的状态
[root@localhost ~]# nmcli device

[root@localhost ~]# nmcli connection

ens33-dhcp 97ab866a-3136-4349-9961-c26524d8d408 802-3-ethernet --
[root@localhost ~]#
7.配置绑定网卡team0 结束，最后重启一下team0和NetworkMnanger就可以了
[root@localhost ~]# nmcli connection down team0 && nmcli connection up team0
