集群 之 ipvsadm 指令

ipvsadm ：定义管理LVS集群的命令行工具

ipvsadm -A|E -t|u|f service-address [-s scheduler] [-p [timeout]] [-M netmask]

-A ：添加一条新的虚拟服务器记录

-E ：编辑虚拟服务器记录

-D ：删除虚拟服务器记录

-C ：清楚所有的虚拟服务器记录

-R ：恢复虚拟服务器规则

-S ：保存虚拟服务器规则

-t  ：tcp协议集群

-u ：udp协议集群

-p ：会话保持时间

-m：指定LVS的工作模式为NAT模式

-g ：指定LVS的工作模式为直接路由

-i ：指定LVS的工作模式为隧道模式
