求助：负载均衡中遇到的问题，大家帮忙来解决一下

dujihong

实验环境，我在vmware下安装了三台计算机，操作系统均为RHEL4u4，要实现http、mysql及ssh服务的负载均衡，两台计算机作为lvs路由器，一台为真实服务器，其中一台lvs路由计算机名为lvs1，外网卡IP为192.168.10.51，内网卡为10.0.10.51，在其上面安装了piranha和ipvsadm软件包，使用piranha设置并开启了数据包转发功能，开机启动piranha-gui和pulse服务，另外一台lvs路由的设置与lvs1类似，真实服务器的IP地址为10.0.10.151网关为10.0.10.50（NAT网关）。但是运行ipvsadm命令时显示
IP Virtual Server version 1.2.0 (size=4096)
Prot LocalAddressort Scheduler Flags
  -> RemoteAddressort           Forward Weight ActiveConn InActConn
TCP  192.168.10.50:ssh wlc
TCP  192.168.10.50:http wlc
  -> 10.0.10.151:http             Masq    1      0          0         
TCP  192.168.10.50:mysql wlc
只有http服务做成功了，难道mysql和ssh服务都必须手动运行ipvsadm -a -t 192.168.10.50:3306 -r 10.0.10.151 -m
ipvsadm -a -t 192.168.10.50:22 -r 10.0.10.151 -m命令才行吗？
