apache tomcat mod_jk集群配置负载均衡，没有负载

Question

先说问题

我看了很多博客，也看了jk的官网设置

配置成功，启动没报错。当启动3个tomcat的时候，远程或者本地访问都是访问tomcat1  2、3只有在1关闭的情况才会去访问

我2、3的lbfactor的权重配置都比1高。不知道为啥。

apache2.4  jk也是官网下载的。求高手帮忙，找出问题

我的项目中Tomcat7/conf/Catalina/中配置了多个host指向Root.xml

也用了druid数据库连接池

求兄弟们帮忙看下为啥

worker.properties配置

worker.list=controller,status 
#========apache-tomcat-1========
worker.tomcat1.port=9009
worker.tomcat1.host=localhost
worker.tomcat1.type=ajp13
worker.tomcat1.lbfactor=1
#========apache-tomcat-2========
worker.tomcat2.port=11009
worker.tomcat2.host=localhost
worker.tomcat2.type=ajp13
worker.tomcat2.lbfactor=2
#========apache-tomcat-3========
worker.tomcat3.port=11009
worker.tomcat3.host=192.168.2.227
worker.tomcat3.type=ajp13
worker.tomcat3.lbfactor=10
#========controller========
worker.controller.type=lb
worker.controller.balance_workers=tomcat1,tomcat2,tomcat3
worker.status.type=status
#worker.controller.sticky_session=true
#worker.controller.sticky_session_force=false

上面是主的tomcat 配置。

后面的其他tomcat 的workers.properties就改成这个就行了

workers.tomcat_home="G:apache-tomcat-7.0.57" 
#让mod_jk模块知道Tomcat的安装路径
workers.java_home="C:Program FilesJavajdk1.7.0_13"
#让mod_jk模块知道jdk路径
worker.list=ajp13
#这里是关键，名字要和httpd.conf的一致。如果这里改了httpd.conf也要改。
worker.ajp13.port=8009
#工作端口,tomcat的jk监听端口，可以查看Server.xml中有port="8009"            
worker.ajp13.host=127.0.0.1 
#Tomcat所在机器，如果安装在与apache不同的机器则需要设置IP
worker.ajp13.type=ajp13
#类型，好像不能改，会出问题
worker.ajp13.lbfactor=1
#负载平衡因子
