apache mod_jk loadbalancing glassfish集群实例问题

Question

我在一个开源的GlassFish v3.1服务器上部署了一个Java EE6 EAR应用程序，该服务器运行在2个集群上的Windows 2003 R2服务器上，每个集群有2个实例。为了平衡工作负载，我正在使用带有mod_jk的apache http服务器。当我查看jk状态页面时，我看到工作正在分发给每个集群中的一个实例，即使所有四个都具有相同的lbfactor为1.任何想法？

这是我的workers.properties config：

worker.list=loadbalancerLocal,status

worker.status.type=status

worker.ViewerLocalInstance1.type=ajp13
worker.ViewerLocalInstance1.host=localhost
worker.ViewerLocalInstance1.port=8109
worker.ViewerLocalInstance1.lbfactor=1
worker.ViewerLocalInstance1.socket_keepalive=1
worker.ViewerLocalInstance1.socket_timeout=1000


worker.ViewerLocalInstance2.type=ajp13
worker.ViewerLocalInstance2.host=localhost
worker.ViewerLocalInstance2.port=8209
worker.ViewerLocalInstance2.lbfactor=1
worker.ViewerLocalInstance2.socket_keepalive=1
worker.ViewerLocalInstance2.socket_timeout=1000

worker.ViewerLocalInstance3.type=ajp13
worker.ViewerLocalInstance3.host=localhost
worker.ViewerLocalInstance3.port=8309
worker.ViewerLocalInstance3.lbfactor=1
worker.ViewerLocalInstance3.socket_keepalive=1
worker.ViewerLocalInstance3.socket_timeout=1000

worker.ViewerLocalInstance4.type=ajp13
worker.ViewerLocalInstance4.host=localhost
worker.ViewerLocalInstance4.port=8409
worker.ViewerLocalInstance4.lbfactor=1
worker.ViewerLocalInstance4.socket_keepalive=1
worker.ViewerLocalInstance4.socket_timeout=1000

worker.loadbalancerLocal.type=lb
worker.loadbalancerLocal.sticky_session=True
worker.loadbalancerLocal.balance_workers=ViewerLocalInstance1,ViewerLocalInstance2,ViewerLocalInstance3,ViewerLocalInstance4

这是我对mod_jk

的httpd配置

LoadModule jk_module modules/mod_jk.so
JkWorkersFile conf/workers.properties
# Where to put jk logs
JkLogFile logs/mod_jk.log
# Set the jk log level [debug/error/info]
JkLogLevel info
# Select the log format
JkLogStampFormat "[%a %b %d %H:%M:%S %Y] "
# JkOptions indicate to send SSL KEY SIZE,
JkOptions +ForwardKeySize +ForwardURICompat -ForwardDirectories
# JkRequestLogFormat set the request format
JkRequestLogFormat "%w %V %T"

JkMount /Viewer/* loadbalancerLocal
JkMount /Viewer loadbalancerLocal
JkMount /jkstatus/* status

您已开启粘性会话。尝试将其关闭。如果设置了jvmRoute，也可能需要取消设置。
