请教一个LVS的问题。（已解决）
本帖最后由 yulihua49 于 2013-12-23 10:37 编辑在sentos 6.2,安装了ipvsadm-1.24。
设置了ssh服务，一个VS，一个RS。
只能工作几秒钟，就断了。
。。。。。。。。。。。。。。。。。。VIP地址有人用了。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。
vs设置：在10.247.53.10cat /sbin/lvs-dr.sh

用ssh呼叫10.247.53.11
可以连上几秒，马上就会：
the host ‘10.247.53.11’is unreachable.
不使用keepalived，ipvsadm能单独工作吗？
