負載均衡問題
我現在用as3.0兩台機子做負載均衡，一台做機頭，一台為realserver，用來做web測試，內核升級為
kernel-smp-2.4.21-27.0.2.EL.um.1.i686.rpm
現在realserver上的tomcat運行正常，只是不是負載，其配置如下，
Director IP(DIP):192.168.0.14
Realserver(RIP):192.168.0.15
Virtual IP (VIP):192.168.0.2
DIP配置

單測http：//192.168.0.15 tomcat運行正常
現在如果輸入http://192.168.0.2頁面不能打開，請指教，

沒人幫忙看看嗎？

回復 1樓 gb8007 的帖子
從ipvsadmin看你配置了2個realserver阿，配置文件是手寫的，還是使用工具配置的？
確認一下浮動ip可以ping通么？ipvs的幾個進程正常運行么（pulse, lvsd, nanny）？
《解決方案》
我的ipvsadm是手寫的，並且192.168.0.2是通的，至於你說的ipvs的幾個進程正常運行么（pulse, lvsd, nanny）是從哪裡察看？

《解決方案》
問題已經解決了，還是自己的粗心造成了開始的失敗
/etc/sysconfig/network-scripts/ifcfg-lo:0
DEVICE=lo:0
IPADD=192.168.0.2
NETMASK=255.255.255.255
NETWORK=192.168.0.0
BROADCAST=192.168.0.255
ONBOOT=yes
NAME=loopback
少些個R，所以這個lo：0沒有正常使用

呵呵，這篇文章不錯，收藏了，做為案例
