apache+tomcat負載均衡，集羣，jdstatus配置（完整）

所需材料：
1，apache_2.0.55-win32-x86-no_ssl.msi
2，apache-tomcat-5.5.17.rar
3，mod_jk-apache-2.0.55.so

步驟及內容：
1，在C:\apacheTomcat\Apache2\conf\httpd.conf末尾添加下面一句話
include "C:\apacheTomcat\Apache2\conf\mod_jk.conf"

2，編寫httpd.conf文件，內容如下：

#加載mod_jk Module
LoadModule jk_module modules/mod_jk-apache-2.0.55.so
#指定 workers.properties文件路徑
JkWorkersFile conf/workers.properties
#指定請求交給tomcat處理,"controller"爲在workers.propertise裏指定的負載分配控制器
JkMount /*.jsp controller
JkMount /jkstatus status

3，在目錄C:\apacheTomcat\Apache2\conf\下添加文件
workers.properties，內容爲：

worker.list = controller,status  #server 列表
worker.status.type=status

#========tomcat1========

worker.tomcat1.port=8009         #ajp13端口號，在tomcat下server.xml配置,默認8009
worker.tomcat1.host=localhost  #tomcat的主機地址，如不爲本機，請填寫ip地址
worker.tomcat1.type=ajp13
worker.tomcat1.lbfactor = 1   #server的加權比重，值越高，分得的請求越多

#========tomcat2========

worker.tomcat2.port=9009       #ajp13端口號，在tomcat下server.xml配置,默認8009
worker.tomcat2.host=localhost  #tomcat的主機地址，如不爲本機，請填寫ip地址
worker.tomcat2.type=ajp13
worker.tomcat2.lbfactor = 1   #server的加權比重，值越高，分得的請求越多


#========controller,負載均衡控制器========
worker.controller.type=lb
worker.retries=3
worker.controller.balanced_workers=tomcat1,tomcat2   #指定分擔請求的tomcat
worker.controller.sticky_session=1

4，複製tomcat兩份，配置其中server.xml，其中tomcat1的配置文件內容如下：

<Server port="8005" shutdown="SHUTDOWN">

  <Listener className="org.apache.catalina.core.AprLifecycleListener" />
  <Listener className="org.apache.catalina.mbeans.ServerLifecycleListener" />

        </Cluster>

      </Host>
    </Engine>

創建項目test並放進tomcat1，tomcat2中。
其中web.xml內容如下：

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5" 
	xmlns="http://java.sun.com/xml/ns/javaee" 
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
	xsi:schemaLocation="http://java.sun.com/xml/ns/javaee 
	http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">
   <display-name></display-name>	

    <welcome-file-list>
      <welcome-file>index.jsp</welcome-file>
    </welcome-file-list>	
    <distributable/> 
</web-app>

創建測試jsp

<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
    pageEncoding="ISO-8859-1"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Insert title here</title>
</head>
<body>
   <% 
       HttpSession session2 = request.getSession();
       System.out.println(session2.getId());
   %>

</body>
</html>

最後請求：http://localhost/test/testSession.jsp即可
