apache+tomcat+mod_jk load balance

1. tomcat1, tomcat2,  修改端口

tomcat1 : 

8005, 8080, 8009 

<Engine name="Standalone" defaultHost="localhost" jvmRoute="tomcat1"> 

tomcat2 : 

7005, 7080, 7009

    <Engine name="Standalone" defaultHost="localhost" jvmRoute="tomcat1"> 

2. apache 下载mod_jk.so放入modules目录下

http.conf 

LoadModule jk_module modules/mod_jk.so

引入mod_jk.conf : Include "xxx/mod_jk.conf"

新建mod_jk.conf

<IfModule !mod_jk.c>

LoadModule jk_module modules/mod_jk.so

</IfModule>

JkWorkersFile "xxx\workers.properties" ##引入workers.properties文件

JkLogFile "xxx\logs\mod_jk.log"

<VirtualHost *:80>

ServerName xxx:80

JKMount /balance-status balancestatus

JKMount /* ajp13

</virtualHost>

新建workers.properties 文件

worker.list=ajp13, balancestatus   ##mod_jk.conf 中定义的 JkMount

worker.tomcat1.port=8009       ## tomcat1 为tomcat中定义的jvmRoute

worker.tomcat1.host=localhost  ##另外电脑则填ip

worker.tomcat1.type=ajp13    ##类型ajp13 跟list中ajp13不同 默认

worker.tomcat1.lbfactor=1     ##负载参数

worker.tomcat2.port=7009

worker.tomcat2.host=localhost

worker.tomcat2.type=ajp13

worker.tomcat2.lbfactor=1

worker.ajp13.type=lb

worker.ajp13.balance_workers=tomcat1,tomcat2  ##jvmRoute

worker.ajp13.socket_timeout=200   ##秒

worker.ajp13.sockt_keepalive=true

worker.ajp13.connection_pool_timeout=600   ##秒  

worker.ajp13.sticky_session=1   ##1/>1/true 代表自始至终连接同一个tomcat，0/false 请求在多个tomcat中间串不一定是哪一个tomcat在处理请求

worker.balancestatus.type=status  ## 当访问/balance-status的时候，可以看到load balance tomcat服务器状态

tomcat中 connectionTimeout: 毫秒

<Connectorport="8080" protocol="HTTP/1.1" connectionTimeout="20000" redirectPort="8443" />

<Connector port="8009" protocol="AJP/1.3" maxThreads="400" minSpareThreads="25" backlog="100" connectionTimeout="600000" enableLookups="false" redirectPort="8443" />
