我通过红帽5.4的piranha 图形化工具配置LVS  采用DR模式   其中192.168.1.110 和192.168.1.111是真实主机的IP地址   VIP是192.168.1.200
192.168.1.100主机是LVS的主程序所在主机     
具体的lvs.cf配置文件如下
[root@AR ~]# ifconfig

ipvsadm是空的   重装了好几次都是这样  请大家帮忙看看  是我哪里配置的不对，谢谢大家

贴出日志信息

192.168.1.110
192.168.1.111

的80端口都是正常的吗

这两个IP地址80端口都是正常  主要的问题就是在AR主机上用ipvsadm命令看不到路由表  很奇怪

找到一些错误日志  一直显示111和110主机的80端口timeout  但是我刚才从AR主机上telnet 这两个主机的80端口没问题  另外这两个主机的iptables和selinux都已经关闭了。还有那些地方需要设置呢？

现在经过测试发现LVS已经开始工作了 通过WEB页面访问192.168.1.200这个虚拟IP已经可轮询真实主机的WEB界面了，在AR主机上用命令ipvsadm查看LVS状态还是空的

CURRENT LVS ROUTING TABLE
IP Virtual Server version 1.2.1 (size=4096)
Prot LocalAddressort Scheduler Flags
-> RemoteAddressort Forward Weight ActiveConn InActConn

这是怎么回事啊。。。太诡异了

问题已经解决了，我自己还配置了一个AR主机192.168.1.100的冗余BR主机192.168.1.101   LVS自己切换的到BR主机上去了而我一直在AR主机上用ipvsadm查看当然啥都看不出来了，呵呵。在BR主机上就能看到正确的连接表。
