注：此試驗主要介紹'activebackup' 網絡卡熱備份模式

1、建立虛擬網絡卡組

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

      命令格式簡單說明：nmcli connection  新增    型別為    team（組隊）
                                          配置檔名   team0   網絡卡名  team0
                                         每次開機自動啟用
                                         工作模式為     熱備份

  可以使用man命令輔助：man teamd.conf

# man teamd.conf               #man幫助
EXAMPLES
       {
         "device": "team0",
         "runner": {"name": "roundrobin"},
         "ports": {"eth1": {}, "eth2": {}}
       }

       Very basic configuration.

       {
         "device": "team0",
         "runner": {"name": "activebackup"},
         "link_watch": {"name": "ethtool"},

# nmcli connection add type team con-name team0 ifname team0 autoconnect yes config '{"runner": {"name": "activebackup"}}'
Connection 'team0' (e29ceff9-4944-4a2f-b5db-f52bbb5c0263) successfully added.
# ifconfig team0    ###建立成功後檢視
team0: flags=4099<UP,BROADCAST,MULTICAST>  mtu 1500
        ether c6:8c:c4:9b:c6:1f  txqueuelen 0  (Ethernet)
        RX packets 0  bytes 0 (0.0 B)
        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 0  bytes 0 (0.0 B)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0
 

 2.給組裡新增成員

     命令：#nmcli connection add type  team-slave 
   con-name team0-2 ifname eth2  master team0

     命令簡介：# nmcli connection 新增  型別   team-成員
     配置檔名為  team0-2  網絡卡名  eth2 主裝置  為team0

# nmcli connection add type team-slave con-name team0-1 ifname eth0 master team0
Connection 'team0-1' (bf3afedf-0b07-488c-9215-29159b0b5f3a) successfully added.
########新增網絡卡eth0到team0
# nmcli connection add type team-slave con-name team0-2 ifname eth1 master team0
Connection 'team0-2' (068fe4ac-8463-4033-b82d-de0916b74103) successfully added.
########新增網絡卡eth1到team0
 

3. 為虛擬網絡卡team0配置IP地址

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

 4.啟用配置

[[email protected] ~]# nmcli connection up team0
Connection successfully activated (D-Bus active path: /org/freedesktop/NetworkManager/ActiveConnection/3)
# nmcli connection up team0-1
# nmcli connection up team0-2

5.測試效果

檢視鏈路聚合狀態的命令

# ifconfig  eth0  down             如果網絡卡1down掉
# teamdctl  team0 state         檢視但前team0的狀態

6.其他

#nmcli  connection  delete  team0     #刪除team0配置
