centos+lvs+heartbeat 实现负载均衡访问慢。

vodcms

三台服务器
A:192.0.0.231 主
B:192.0.0.232
C:192.0.0.233
VIP:为虚拟服务器

A与B都安装了。heartbeat+LVS+ldirectord

ldirectord
配置：

checktimeout=3 checkinterval=1 #fallback=127.0.0.1:80 autoreload=yes logfile="/var/log/ldirectord.log" #logfile="local0" #emailalert="admin@x.y.z" #emailalertfreq=3600 #emailalertstatus=all quiescent=yes # Sample for an http virtual service virtual=192.0.0.230:80         real=192.0.0.231:80 gate         real=192.0.0.232:80 gate         #real=192.0.0.233:80 gate         fallback=127.0.0.1:80 gate         service=http         request="test.html"         receive="Test Page"         #virtualhost=some.domain.com.au         scheduler=rr         #persistent=600         #netmask=255.255.255.255         protocol=tcp         checktype=negotiate         checkport=80         request="test.html"         receive="Test Page"         #virtualhost=www.x.y.z

访问http://192.0.0.230页面非常慢。检测出现连接超时。
请教各位原因。

你设置的可能有问题...

看一下log 有什么信息...

有个奇特的现象，
我只要关闭2个real server中的一台服务器。速度就飞快。但是rr调度的时候调用2个real server的WEB。就非常大慢。时常丢失连接提示超时
