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 
DEVICE       TYPE      STATE      CONNECTION  
virbr0       bridge    connected  virbr0      
eno16777736  ethernet  connected  team0-port1 
ens38        ethernet  connected  team0-port2

[root@localhost ~]# nmcli connection

[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
