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
