Apache+Tomcat负载平衡

1，安装apache2，到c:\apache2，

2，下载mod_jk.dll，复制到c:\apache2\modules

3，修改c:\apache2\conf\httpd.conf，添加

LoadModule jk_module modules/mod_jk_2.0.47.dll
JkWorkersFile "C:/Apache2/conf/workers2.properties"
JkMount /*.jsp loadbalancer 
JkMount /*.do loadbalancer 
JkMount /servlet/* loadbalancer 
JkLogFile "c:/Apache2/logs/mod_jk2.log"
JkLogLevel INFO

4，在c:\apache2\conf目录下建立worker2.properties内容

ps=/ 

worker.list=tomcat1,tomcat2,loadbalancer 

worker.tomcat1.port=11009
worker.tomcat1.host=10.1.19.80
worker.tomcat1.type=ajp13 
#worker.tomcat1.cachesize 
 
worker.tomcat1.lbfactor=100 
 
worker.tomcat2.port=12009
worker.tomcat2.host=10.1.19.80
worker.tomcat2.type=ajp13 
#worker.tomcat2.cachesize 

worker.tomcat2.lbfactor=100 
 
worker.loadbalancer.type=lb 
worker.loadbalancer.balanced_workers=tomcat1, tomcat2 

 

5，下载tomcat5.5.5的zip版，分别解压缩到c:\tomcat1 ,c:\tomcat2

修改c:\tomcat1\conf\jk2.properties

channelSocket.port=11009

修改c:\tomcat2\conf\jk2.properties

channelSocket.port=12009

6，修改c:\tomcat1\conf\server.xml

(1)<Server port="11005" shutdown="SHUTDOWN">

(2)<Connector port="11080"
               maxThreads="150" minSpareThreads="25" maxSpareThreads="75"
               enableLookups="false" redirectPort="8443" acceptCount="100"
               connectionTimeout="20000" disableUploadTimeout="true" />

(3)<Engine  name="Catalina" defaultHost="localhost"  jvmRoute="tomcat1">

(4)去掉cluster的注释

在该tcpListenPort为4001

7，修改c:\tomcat2\conf\server.xml

(1)<Server port="12005" shutdown="SHUTDOWN">

(2)<Connector port="12080"
               maxThreads="150" minSpareThreads="25" maxSpareThreads="75"
               enableLookups="false" redirectPort="8443" acceptCount="100"
               connectionTimeout="20000" disableUploadTimeout="true" />

(3)<Engine  name="Catalina" defaultHost="localhost"  jvmRoute="tomcat2">

(4)去掉cluster的注释

在该tcpListenPort为4002

8，c:\tomcat1\bin\startup.bat 第一行加入set TOMCAT_HOME=c:\tomcat1

c:\tomcat2\bin\startup.bat 第一行加入set TOMCAT_HOME=c:\tomcat2

9，启动apache2,两个tomcat，OK
