team,聚合连接(链路聚合)


由多块网卡(team-slave)一起组建而成的虚拟网卡,

即“组队”

 作用1:轮询式(roundrobin)的流量负载均衡


 作用2:热备份(activebackup)连接冗余


热备份配置 : {"runner":{"name":"activebackup"}}


man帮助辅助 :


man teamd.conf   --> /example   #全文查找example #按n 跳转下一个匹配


一、添加team组设备

# nmcli connection add type team con-name team0 ifname team0 config '{"runner": {"name": "activebackup"}}'

# type类型 # con-name设备文件名  # ifname设备名 # config配置

# cat /etc/sysconfig/network-scripts/ifcfg-team0

# ifconfig team0


二、添加组成员(eth1和eth2)

# nmcli connection add type team-slave ifname eth1 master team0 #con-name # 可省略(自动命名设备文件名) 则省

# nmcli connection add type team-slave ifname eth2 master team0


三、配置team0的IP地址

# nmcli connection modify team0 ipv4.method manual ipv4.addresses ‘192.168.1.1/24 192.168.1.254’ connection.autoconnect yes


四、激活team0

# nmcli connection up team-slave-eth1   #激活从设备eth1

# nmcli connection up team-slave-eth2   #激活从设备eth2

# nmcli connection up team0                    #激活主设备team0     


五、验证

# teamdctl team0 state                               #专用于查看team信息


注:删除

# nmcli connection delete team-slave-eth1 

# nmcli connection delete team-slave-eth2

# nmcli connection delete team0
