linux配置聚合链路

2018年09月04日 15:27:01 阅读数：6

聚合连接（team）：指的是网络连接的捆绑/组队，通过将多个实际网卡（team-slave）整和为逻辑上的单个连接，实现负载均衡，热备份等单块网卡难以完成的特殊功能。

聚合连接的类型：热备份activebackup，轮询负载均衡roundrobin

定义聚合连接的类型配置时，采用JSON语法，主要特点如下：

标记一个对象–（对象）

每个对象 —名称：值

每个字符串—“字符串”

热备份-聚合连接（activebackup）

[root@zhuhaiyan ~]# nmcli con modify team0 ipv4.method manual ipv4.addresses 172.16.3.20/24 connection.autoconnect yes
[root@zhuhaiyan ~]# nmcli con add con-name team0-p1 type team-slave ifname eth1 master team0
连接“team0-p1”(4b565f4d-c02c-42e7-8b40-62c76db0b2c0) 已成功添加。
[root@zhuhaiyan ~]# nmcli con add con-name team0-p2 type team-slave ifname eth2 master team0
连接“team0-p2”(1e8f123c-f407-44d7-8be2-2dbb029b1ec0) 已成功添加。
[root@zhuhaiyan ~]# nmcli connection up team0
成功激活（主服务器等待从服务器）连接（D-Bus 激活路径：/org/freedesktop/NetworkManager/ActiveConnection/11）
[root@zhuhaiyan ~]# nmcli connection up team0-p1
连接已成功激活（D-Bus 活动路径：/org/freedesktop/NetworkManager/ActiveConnection/14）
[root@zhuhaiyan ~]# nmcli connection up team0-p2
连接已成功激活（D-Bus 活动路径：/org/freedesktop/NetworkManager/ActiveConnection/15）
