两台服务器
[root@localhost ~]# ipvsadm -L -n
IP Virtual Server version 1.2.1 (size=4096)
Prot LocalAddress:Port Scheduler Flags
-> RemoteAddress:Port Forward Weight ActiveConn InActConn
TCP 192.168.1.50:80 rr
-> 192.168.1.122:80 Route 1 0 0
-> 192.168.1.123:80 Route 1 0 0

这问题到底出在哪里? 而且是可以互相ping 虚拟ip 192.168.1.50没有问题的
