网络组Network Team
网络组team:是将多个网卡聚合在一起,从而实现容错和提高吞吐量
1 创建网络组接口
nmcli connection add type team con-name TEAMname ifname INTname [config JSON]
TEAMname 指定连接名,INname指定接口名,
JSON指定runner方式,格式为:'{“runner”:{“name”:”METHOD”}}’
METHOD 可以是broadcast、roundrobin、activebackup、loadbalance、lacp
(1)创建网络接口组team0
[root@centos7 ~]# nmcli connection add type team con-name team0 ifname team0 config '{"runner":{"name":"loadbalance"}}' Connection 'team0' (e70483a1-2688-4eb2-9466-8e732360291d) successfully added.
(2)给网路组team0配置IP地址
[root@centos7 ~]# nmcli connection modify team0 ipv4.method manual ipv4.addresses 200.200.200.200/24 gw4 200.200.200.1
2 创建port接口(SLAVE)
既就是生成组TEAM组成员的配置文件。
注意:这个配置文件和网卡配置文件是相互独立的。
nmcli connection add type team-slave con-name SLAVEname ifname INname master TEAMname
SLAVEname 指定连接名,INTname指定网络接口名(相当于指定要加入网络组的网卡名),TEAMnmae指定所属网络组。
若连接名不指定,默认为team-slave-IFACE
创建接口组
这里使用ens34、ens38两块网卡
[root@centos7 ~]# nmcli connection add con-name team0-ens34 type team-slave ifname ens34 master team0 Connection 'team0-ens34' (a481fb6d-bf61-413d-a2c7-289966bee1a7) successfully added. [root@centos7 ~]# nmcli connection add con-name team0-ens38 type team-slave ifname ens38 master team0 Connection 'team0-ens38' (758d0eba-1625-46b2-b539-1d853a45be6b) successfully added.
3 启用网络组
启用网络组:nmcli connection up team0
启用组成员:nmcli connection up SLAVEname
[root@centos7 ~]# nmcli connection up team0 Connection successfully activated (master waiting for slaves) (D-Bus active path: /org/freedesktop/NetworkManager/ActiveConnection/20) [root@centos7 ~]# nmcli connection up team0-ens34 Connection successfully activated (D-Bus active path: /org/freedesktop/NetworkManager/ActiveConnection/23) [root@centos7 ~]# nmcli connection up team0-ens38 Connection successfully activated (D-Bus active path: /org/freedesktop/NetworkManager/ActiveConnection/24)
4 查看网络组状态
teamdctl TEAMname state
[root@centos7 ~]# teamdctl team0 state setup: runner: loadbalance ports: ens34 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
5 网络组配置文件
(1)MASTER配置文件
[root@centos7 ~]# cat /etc/sysconfig/network-scripts/ifcfg-team0 DEVICE=team0 TEAM_CONFIG="{"runner":{"name":"loadbalance"}}" BOOTPROTO=none DEFROUTE=yes IPV4_FAILURE_FATAL=no NAME=team0 UUID=e70483a1-2688-4eb2-9466-8e732360291d ONBOOT=yes DEVICETYPE=Team IPADDR=200.200.200.200 PREFIX=24 GATEWAY=200.200.200.1
(2)组成员(SLAVE)配置文件
[root@centos7 ~]# cat /etc/sysconfig/network-scripts/ifcfg-team0-ens34 NAME=team0-ens34 UUID=a481fb6d-bf61-413d-a2c7-289966bee1a7 DEVICE=ens34 ONBOOT=yes TEAM_MASTER=team0 DEVICETYPE=TeamPort
6 删除网络组
(1)断开连接
[root@centos7 ~]# nmcli connection down team0 Connection 'team0' successfully deactivated (D-Bus active path: /org/freedesktop/NetworkManager/ActiveConnection/7)
查看下状态
[root@centos7 ~]# teamdctl team0 state Device "team0" does not exist [root@centos7 ~]# nmcli connection show NAME UUID TYPE DEVICE ens33 be9d1f2f-20e0-4282-9cb5-0da4c8b0fc7c 802-3-ethernet ens33 virbr0 8b1532d4-d99b-4201-8163-44d733302230 bridge virbr0 team0 e70483a1-2688-4eb2-9466-8e732360291d team -- team0-ens34 a481fb6d-bf61-413d-a2c7-289966bee1a7 802-3-ethernet -- team0-ens38 758d0eba-1625-46b2-b539-1d853a45be6b 802-3-ethernet --
可以看到已经关闭成功
(2)删除TEAM组成员
[root@centos7 ~]# nmcli connection delete team0-ens34 Connection 'team0-ens34' (a481fb6d-bf61-413d-a2c7-289966bee1a7) successfully deleted. [root@centos7 ~]# nmcli connection delete team0-ens38 Connection 'team0-ens38' (758d0eba-1625-46b2-b539-1d853a45be6b) successfully deleted.
(3)删除TEAM组
[root@centos7 ~]# nmcli connection delete team0 Connection 'team0' (e70483a1-2688-4eb2-9466-8e732360291d) successfully deleted.
查看一下
[root@centos7 ~]# nmcli connection show NAME UUID TYPE DEVICE ens33 be9d1f2f-20e0-4282-9cb5-0da4c8b0fc7c 802-3-ethernet ens33 virbr0 8b1532d4-d99b-4201-8163-44d733302230 bridge virbr0
已经看不到team0 相关的内容,说明删除成功
