apache+mod_jk_tomcat

1.下载mod_jk-1.2.28-httpd-2.2.3.so放到modules下

2.新建tomcat1：D:/tomcat/tomcat1；

新建tomcat2：D:/tomcat/tomcat2

3.修改 D:/tomcat/tomcat1/conf/server.xml文件

<?xml version='1.0' encoding='utf-8'?>

<Server port="8501" shutdown="SHUTDOWN">
<Service name="Catalina">

<Connector port="8801" protocol="HTTP/1.1"
               connectionTimeout="20000"
               redirectPort="8443" />

<Connector port="8009" protocol="AJP/1.3" redirectPort="8443" />
        <Engine name="Catalina" defaultHost="localhost">

      <Cluster className="org.apache.catalina.ha.tcp.SimpleTcpCluster"/>

      <Host name="localhost" appBase="webapps"
            unpackWARs="true" autoDeploy="true"
            xmlValidation="false" xmlNamespaceAware="false">

      </Host>
    </Engine>
</Service>
</Server>

修改 D:/tomcat/tomcat2/conf/server.xml文件

<?xml version='1.0' encoding='utf-8'?>

<Server port="8502" shutdown="SHUTDOWN">

<Cluster className="org.apache.catalina.ha.tcp.SimpleTcpCluster"/>

      <Host name="localhost" appBase="webapps"
            unpackWARs="true" autoDeploy="true"
            xmlValidation="false" xmlNamespaceAware="false">

</Host>
</Engine>
</Service>
</Server>

以上为主要修改的地方，其他省略不写

4.修改D:/Program Files/Apache Software Foundation/Apache2.2/conf/httpd.conf文件

最后添加一句:
####################add
include "D:/Program Files/Apache Software Foundation/Apache2.2/conf/mod_jk.conf"

5.新建D:/Program Files/Apache Software Foundation/Apache2.2/conf/mod_jk.conf文件内容为：

#加载mod_jk Module
LoadModule jk_module modules/mod_jk-1.2.28-httpd-2.2.3.so
#指定 workers.properties文件路径
JkWorkersFile conf/workers.properties
#指定那些请求交给tomcat处理,"controller"为在workers.propertise里指定的负载分配控制器
JkMount /*.jsp controller

6.新建 D:/Program Files/Apache Software Foundation/Apache2.2/conf/workers.properties

内容为：

#server 列表
worker.list = controller,tomcat1,tomcat2

#========tomcat1========
worker.tomcat1.port=8009 #ajp13 端口号，在tomcat下server.xml配置,默认8009
worker.tomcat1.host=localhost #tomcat的主机地址，如不为本机，请填写ip地址
worker.tomcat1.type=ajp13
worker.tomcat1.lbfactor = 1 #server的加权比重，值越高，分得的请求越多

#========tomcat2========
worker.tomcat2.port=9009 #ajp13 端口号，在tomcat下server.xml配置,默认8009
worker.tomcat2.host=localhost #tomcat的主机地址，如不为本机，请填写ip地址
worker.tomcat2.type=ajp13
worker.tomcat2.lbfactor = 1 #server的加权比重，值越高，分得的请求越多

#========controller,负载均衡控制器========
worker.controller.type=lb
worker.controller.balanced_workers=tomcat1,tomcat2 #指定分担请求的tomcat
worker.controller.sticky_session=1

7、测试用例：

在 D:/tomcat/tomcat1/webapps/test

D:/tomcat/tomcat2/webapps/test

下新建 test.jsp和WEB-INF文件夹

test.jsp内容为：

      <%@ page contentType="text/html; charset=GBK" %>
<%@ page import="java.util.*" %>
<html><head><title>Cluster App Test</title></head>
<body>
Server Info:
<%
System.out.println(request.getLocalAddr() + " : " + request.getLocalPort()+"<br>");%>
<%
System.out.println("<br> ID " + session.getId()+"<br>");
// 如果有新的 Session 属性设置
String dataName = request.getParameter("dataName");
if (dataName != null && dataName.length() > 0) {
     String dataValue = request.getParameter("dataValue");
     session.setAttribute(dataName, dataValue);
}
System.out.print("<b>Session 列表</b>");
Enumeration e = session.getAttributeNames();
while (e.hasMoreElements()) {
     String name = (String)e.nextElement();
     String value = session.getAttribute(name).toString();
     out.println( name + " = " + value+"<br>");
         System.out.println( name + " = " + value);
   }
%>
<form action="index.jsp" method="POST">
    名称:<input type=text size=20 name="dataName">
     <br>
    值:<input type=text size=20 name="dataValue">
     <br>
    <input type=submit>
   </form>
</body>
</html>

WEB-INF下新建web.xml内容为：

<web-app xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd" version="2.4">
<display-name>TomcatDemo</display-name>
<distributable/>
</web-app>

8、打开 D:/tomcat/tomcat1/bin/startup.bat和D:/tomcat/tomcat2/bin/startup.bat观察到每次

两个tomcat轮流输出结果，输出session值相同
