Team网卡绑定
实验要求：在当前主机添加两块网卡，将两块网卡绑定实现网卡冗余操作
添加网卡
关闭虚拟机，点击虚拟机设置，添加两个网卡。并且通过nmcli device connect ens224命令激活网卡
创建虚拟team网卡，并绑定网卡
[root@localhost ~]# nmcli connection add type team con-name team0 ifname team0 config '{"runner": {"name": "activebackup"}}' Connection 'team0' (a9b9399c-4650-4f50-840c-42864b7321bc) successfully added.
con-name会话文件名
ifname设备名
config '{"runner": {"name": "activebackup"}}'选择team工作模式——主备
Team工作模式
[root@localhost ~]# ll /usr/share/doc/teamd/example_configs/ total 64 -rw-r--r--. 1 root root 305 Jul 26 2020 activebackup_arp_ping_1.conf -rw-r--r--. 1 root root 465 Jul 26 2020 activebackup_arp_ping_2.conf -rw-r--r--. 1 root root 194 Jul 26 2020 activebackup_ethtool_1.conf -rw-r--r--. 1 root root 212 Jul 26 2020 activebackup_ethtool_2.conf -rw-r--r--. 1 root root 241 Jul 26 2020 activebackup_ethtool_3.conf -rw-r--r--. 1 root root 447 Jul 26 2020 activebackup_multi_lw_1.conf -rw-r--r--. 1 root root 285 Jul 26 2020 activebackup_nsna_ping_1.conf -rw-r--r--. 1 root root 318 Jul 26 2020 activebackup_tipc.conf -rw-r--r--. 1 root root 96 Jul 26 2020 broadcast.conf -rw-r--r--. 1 root root 209 Jul 26 2020 lacp_1.conf -rw-r--r--. 1 root root 98 Jul 26 2020 loadbalance_1.conf -rw-r--r--. 1 root root 140 Jul 26 2020 loadbalance_2.conf -rw-r--r--. 1 root root 183 Jul 26 2020 loadbalance_3.conf -rw-r--r--. 1 root root 93 Jul 26 2020 random.conf -rw-r--r--. 1 root root 244 Jul 26 2020 roundrobin_2.conf -rw-r--r--. 1 root root 97 Jul 26 2020 roundrobin.conf
activebackup主备
broadcast广播
lacp动态链路聚合
loadbalance负载均衡
random随机
roundrobin轮循
打开对应的配置文件，获取相应的配置参数
[root@localhost example_configs]# vim activebackup_arp_ping_2.conf #"runner": {"name": "activebackup"}, #打开对应的配置文件，获取相应的配置参数
激活从设备，主设备
给虚拟网卡添加两个从接口
[root@localhost ~]# nmcli connection add type team-slave con-name team0-port1 ifname ens224 master team0 Connection 'team0-port1' (31d8a0d1-4b5e-45db-92c8-b582cc87369d) successfully added. [root@localhost ~]# nmcli connection add type team-slave con-name team0-port2 ifname ens256 master team0 Connection 'team0-port2' (66bef96c-4a57-440a-ade2-d7564c31d348) successfully added.
team-slave定义为team-slave类型
[root@localhost ~]# nmcli connection show NAME UUID TYPE DEVICE team0 a9b9399c-4650-4f50-840c-42864b7321bc team team0 ens160 40da80dd-550a-4230-9eac-5b91a2225793 ethernet ens160 Wired connection 1 02a53879-7e45-398e-a470-cdd7ed03e265 ethernet ens224 Wired connection 2 6ff28c60-be96-3362-96e7-3b9553d7b626 ethernet ens256 team0-port1 31d8a0d1-4b5e-45db-92c8-b582cc87369d ethernet -- team0-port2 66bef96c-4a57-440a-ade2-d7564c31d348 ethernet --
如果添加错误可以通过[root@localhost ~]# nmcli connection delete uuid 66bef96c-4a57-440a-ade2-d7564c31d348 来删除已经添加的从接口
[root@localhost ~]# nmcli connection up team0-port1 Connection successfully activated (D-Bus active path: /org/freedesktop/NetworkManager/ActiveConnection/6) [root@localhost ~]# nmcli connection up team0-port2 Connection successfully activated (D-Bus active path: /org/freedesktop/NetworkManager/ActiveConnection/7) [root@localhost ~]# nmcli connection up team0
激活两个从会话和主会话
测试
[root@localhost ~]# teamdctl team0 stat setup: runner: activebackup ports: ens224 link watches: link summary: up instance[link_watch_0]: name: ethtool link: up down count: 0 ens256 link watches: link summary: up instance[link_watch_0]: name: ethtool link: up down count: 0 runner: active port: ens224
完成之后，可以通过team网卡的虚拟网卡找到真实网卡进行通信
