我使用mod_jk-1.2.31-httpd-2.2.x.so负载平衡与Apcahe 2.2.15和多个实例的apache tomcat 6 RHEL6 LINUXOS.我有创建workers.properties

     worker.list=stat,balancer   
     worker.worker1.port=8019  
     worker.worker1.host=localhost   
     worker.worker1.type=ajp13  
     worker.worker1.lbfactor=1   
     worker.worker2.port=8029  
     worker.worker2.host=localhost   
     worker.worker2.type=ajp13  
     worker.worker2.lbfactor=1   
     worker.balancer.type=lb  
     worker.stat.type=status  
     worker.balancer.balance_workers=worker1,worker2  
     worker.balancer.method=B   
     worker.balancer.sticky_session=True

在httpd. conf

LoadModule jk_module modules/mod_jk-1.2.31-httpd-2.2.x.so

# Load workers files from the config directory "/etc/httpd/conf".    
JkWorkersFile /etc/httpd/conf/workers.properties
## Path to jk logs 
JkLogFile logs/mod_jk.log 
JkShmFile run/mod_jk.shm
# Jk log level [debug/error/info] 
JkLogLevel info
# Jk log format 
JkLogStampFormat "[%a %b %d %H:%M:%S %Y] "
# JkOptions for forwarding 
JkOptions +ForwardKeySize +ForwardURICompat -ForwardDirectories
# JkRequestLogFormat set the request format 
JkRequestLogFormat "%w %V %T" 
JkMount /status stat 
JkMount /Oa balancer 
JkMount /Oa/* balancer

如果调用挂载Webproject Oa然后在日志mod_jk. log

请建议我，我可以使用ajp连接器8019,8029…代替默认端口8009吗？它是如何工作的？如果有，请发送文档以在一个系统中对多个tomcat实例进行负载平衡。
