修改配置文件，按日期创建日志。
CustomLog “|D:/apache2/bin/rotatelogs.exe D:/apache2/logs/access_%Y_%m_%d.log 86400 480” common
ErrorLog “|D:/apache2/bin/rotatelogs.exe D:/apache2/logs/error_%Y_%m_%d.log 86400 480”
Tomcat6 : http://tomcat.apache.org/download-60.cgi
下载：apache-tomcat-6.0.36.exe
apache httpd server 2.2: http://www.fayea.com/apache-mirror//httpd/binaries/win32/
下载：httpd-2.2.22-win32-x86-no_ssl.msi
apache tomcat connector: http://archive.apache.org/dist/tomcat/tomcat-connectors/jk/binaries/win32/jk-1.2.31/
下载：mod_jk-1.2.31-httpd-2.2.3.so
安装路径：
E:\Apache2.2
E:\apache-tomcat-6.0.36-1
E:\apache-tomcat-6.0.36-2
项目路径：
E:\work\demo
修改 E:\Apache2.2\conf\httpd.conf 文件。
1）、加载外部配置文件：
文件最后一行加上
include conf/mod_jk.conf
2）配置项目路径：
<IfModule alias_module>
Alias /demo "E:/work/demo"
ScriptAlias /cgi-bin/ "E:/Apache2.2/cgi-bin/"
</IfModule>
3）配置目录权限：
<Directory "E:/work/demo"> Order Deny,Allow Allow from all </Directory>
4）配置默认首页：
增加 index.jsp
<IfModule dir_module>
DirectoryIndex index.jsp index.html
</IfModule>
5）增加 E:\Apache2.2\conf\mod_jk.conf 文件内容：
LoadModule jk_module modules/mod_jk-1.2.31-httpd-2.2.3.so 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名 JkMount /*.jsp controller
同时将 mod_jk-1.2.31-httpd-2.2.3.so 文件放入 E:\Apache2.2\modules 文件夹下。
6）增加 E:\Apache2.2\conf\workers.properties 文件内容：
#server worker.list = controller #========tomcat1======== worker.tomcat1.port=10009 worker.tomcat1.host=localhost worker.tomcat1.type=ajp13 worker.tomcat1.lbfactor = 1 #========tomcat2======== worker.tomcat2.port=11009 worker.tomcat2.host=localhost worker.tomcat2.type=ajp13 worker.tomcat2.lbfactor = 1 #========controller,负载均衡控制器======== worker.controller.type=lb worker.controller.balanced_workers=tomcat1,tomcat2 worker.controller.sticky_session=false worker.controller.sticky_session_force=1 #worker.controller.sticky_session=1
1）Tomcat-1 配置
E:\apache-tomcat-6.0.36-1\conf\server.xml
需要修改端口的地方：
<Server port="10005" shutdown="SHUTDOWN">
<Connector port="10080" URIEncoding="GBK" protocol="HTTP/1.1" connectionTimeout="20000" keepAliveTimeout="15000" maxKeepAliveRequests="1" redirectPort="8443" />
<Connector port="10009" protocol="AJP/1.3" redirectPort="8443" />
<Engine name="Catalina" defaultHost="localhost" jvmRoute="tomcat1"> <Cluster className="org.apache.catalina.ha.tcp.SimpleTcpCluster"/>
1）Tomcat-2 配置
E:\apache-tomcat-6.0.36-2\conf\server.xml
需要修改端口的地方：
<Server port="11005" shutdown="SHUTDOWN">
<Connector port="11080" URIEncoding="GBK" protocol="HTTP/1.1" connectionTimeout="20000" keepAliveTimeout="15000" maxKeepAliveRequests="1" redirectPort="8443" />
<Connector port="11009" protocol="AJP/1.3" redirectPort="8443" />
<Engine name="Catalina" defaultHost="localhost" jvmRoute="tomcat2"> <Cluster className="org.apache.catalina.ha.tcp.SimpleTcpCluster"/>
项目 web.xml 文件需在 <web-app>下增加<distributable/>。
test.jsp
<%@ page contentType="text/html; charset=GBK"%>
<%@ page import="java.util.*"%>
<html>
<head>
<title>Cluster App Test</title>
</head>
<body>
Server Info:
<%
out.println(request.getLocalAddr() + " : " + request.getLocalPort() + "<br>");
%>
<%
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);
}
out.println("<b>Session 列表</b><br>");
System.out.println("============================");
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="test.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>
先启动Apache2服务，之后依次启动两个tomcat。
分别访问：
http://127.0.0.1:10080/test.jsp
http://127.0.0.1:11080/test.jsp
http://127.0.0.1/test.jsp
接下来测试你懂得，三者 seesion 内容一致即配置成功。
1、若测试结果不成功，可以查看日志看看报什么错误，是否配置疏忽了什么环节，apache的权限有没有配置等，注意版本；
2、放在session里的对象需要序列化，即类 implements Serializable。
