1、环境介绍
[root@rhcc ~]# cat /etc/redhat-release CentOS Linux release 7.5.1804 (Core) ENERAL.DEVICE: ens37 GENERAL.TYPE: ethernet GENERAL.HWADDR: 00:0C:29:04:8C:9B 192.168.137.128/24 192.168.137.0/24 192.168.137.1 GENERAL.DEVICE: ens38 GENERAL.TYPE: ethernet GENERAL.HWADDR: 00:0C:29:04:8C:A5 192.168.137.129/24 192.168.137.1 因为是在虚拟机中进行的实验只能进行高可用测试 聚合链路的几种模式： broadcast 传输所有端口进来的数据包 roundrobin 随机计算发送数据（轮询） activebackup 高可用性 loadbalance 负载均衡 josn的配置{"runner": {"name":"activebackup"}} ##模式修改只需修改这个格式中的name字段的值2、几种做聚合链路的方式 2.1 图形化
[root@rhcc ~]# nmtui-editJSON配置模式在team0这个虚拟网卡里配置 配置完成后重启网卡
[root@rhcc ~]# systemctl restart network [root@rhcc ~]# ip a --- 5: ens37: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast master team0 state UP group default qlen 1000 link/ether 00:0c:29:04:8c:9b brd ff:ff:ff:ff:ff:ff 6: ens38: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast master team0 state UP group default qlen 1000 link/ether 00:0c:29:04:8c:9b brd ff:ff:ff:ff:ff:ff 10: team0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP group default qlen 1000 link/ether 00:0c:29:04:8c:9b brd ff:ff:ff:ff:ff:ff inet 192.168.137.128/24 brd 192.168.137.255 scope global noprefixroute team0 valid_lft forever preferred_lft forever inet6 fe80::f39f:f544:b69f:48db/64 scope link noprefixroute valid_lft forever preferred_lft forever ---2.2 命令行
第一种 [root@rhcc ~]# man nmcli-examples 找到以下照着模板抄 $ nmcli con add type team con-name Team1 ifname Team1 config team1-ma ster-json.conf $ nmcli con add type ethernet con-name Team1-slave1 ifname em1 master Team1 $ nmcli con add type ethernet con-name Team1-slave2 ifname em2 master Team1 这是我本地的网卡名称 ens37: link/ether 00:0c:29:04:8c:9b ens38: link/ether 00:0c:29:04:8c:a5 [root@rhcc ~]# nmcli con add type team con-name Team1 ifname Team1 config '{"runner":{"name":"activebackup"}}' [root@rhcc ~]# nmcli con add type ethernet con-name Team1-slave1 ifname ens37 master Team1 [root@rhcc ~]# nmcli con add type ethernet con-name Team1-slave2 ifname ens38 master Team1 第二种 [root@rhcc 1]# pwd /usr/share/doc/teamd-1.27/example_ifcfgs/1 [root@rhcc 1]# ls ifcfg-eth1 ifcfg-eth2 ifcfg-team_test0 这里是team的模板配置文件，直接复制到网卡的配置文件目录修改修改 cd /etc/sysconfig/network-scripts/ 18 ls 19 mv ifcfg-eth1 ifcfg-ens37 20 mv ifcfg-eth2 ifcfg-ens38 21 vim ifcfg-ens37 22 vim ifcfg-ens38 23 vim ifcfg-team_test0 24 systemctl restart network [root@rhcc network-scripts]# cat ifcfg-ens37;cat ifcfg-ens38 DEVICE="ens37" DEVICETYPE="TeamPort" ONBOOT="yes" TEAM_MASTER="team_test0" DEVICE="ens38" DEVICETYPE="TeamPort" ONBOOT="yes" TEAM_MASTER="team_test0" [root@rhcc network-scripts]# cat ifcfg-team_test0 DEVICE="team_test0" DEVICETYPE="Team" ONBOOT="yes" BOOTPROTO=none NETMASK=255.255.255.0 IPADDR=192.168.137.128 GATEWAY=192.168.137.1 TEAM_CONFIG='{"runner": {"name": "roundrobin"}}' 5: ens37: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast master team_test0 state UP group default qlen 1000 link/ether 00:0c:29:04:8c:9b brd ff:ff:ff:ff:ff:ff 6: ens38: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast master team_test0 state UP group default qlen 1000 link/ether 00:0c:29:04:8c:9b brd ff:ff:ff:ff:ff:ff 7: team_test0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP group default qlen 1000 link/ether 00:0c:29:04:8c:9b brd ff:ff:ff:ff:ff:ff inet 192.168.137.128/24 brd 192.168.137.255 scope global noprefixroute team_test03、总结 链路聚合主要是备份网卡，实现网卡交互工作，避免网卡单点故障，提高系统的可靠性。其中除了做热备份（activebackup）连接冗余，其他的模式是需要交换机做[EtherChannel (PAgP and LACP) 以太通道]
