apache tomcat mod_jk集群配置负载均衡,没有负载

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

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 Files\Java\jdk1.7.0_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

@红薯 编辑器有点坑呀

哥,我看了下,是懂您的意思的。。。我还想问点问题

我在官网看到的好像tomcat有配置jvmRoute 就是在

Engine 这个节点上

还有就是VirtualHost配置了,那我tomcat中server.xml中配置了多了个Host

<Host name="www.xxx.com"  appBase="webapps"
            unpackWARs="true" autoDeploy="true">
</Host>
	   
<Host name="service.xxx.com"  appBase="webapps"
            unpackWARs="true" autoDeploy="true">
</Host>



在conf中配置了 \conf\Catalina\admin.xxx.com, \conf\Catalina\www.xxx.com   

如果在VirtualHost中配置了。这里配置就无效了吗?
