下載apache
http://apache.mirror.phpchina.com/httpd/httpd-2.2.9-win32-src.zip
下載mod_jk-1.2.26-httpd-2.2.4.so
http://apache.mirror.phpchina.com/tomcat/tomcat-connectors/jk/binaries/win32/jk-1.2.26/
下載tomcat6
下載JDK6
然后配置好環(huán)境。
步驟1：
安裝apache，然后測試http://localhost：80/，可以顯示的話表示apache安裝成功。
把mod_jk-1.2.26-httpd-2.2.4.so 改名為mod_jk，并復(fù)制到apache的安裝目錄的modules下。
步驟2：
修改apache，conf目錄下的httpd文件，增加以下內(nèi)容（根據(jù)自己的情況增減）
LoadModule jk_module modules/mod_jk.so
JkWorkersFile "C:\Program Files/Apache Software Foundation/Apache2.2/conf/workers.properties"
JkLogFile "C:\Program Files/Apache Software Foundation/Apache2.2/logs/mod_jk.log"
JkLogLevel severe
JkMount /*.do controller
JkMount /*.jsp controller
JkMount /WEB-INF/* controller
JkMount /lzj1/*.do controller
步驟3：
在conf目錄下增加uriworkermap.properties文件
再增加workers.properties文件，增加或修改以下內(nèi)容（根據(jù)自己的情況而定）
workers.tomcat_home="E:\java\apache-tomcat-6.0.16\apache-tomcat-6.0.16"
workers.java_home="C:\Program Files\Java\jdk1.6.0_06"
worker.list=controller,tomcat1,tomcat2
worker.tomcat1.host=192.168.10.55
worker.tomcat1.port=8009
worker.tomcat2.port=8009
worker.tomcat2.host=localhostworker.controller.type=lb
worker.controller.balanced_workers=tomcat1,tomcat2
worker.controller.sticky_session=1
worker.ajp13.lbfactor=1
worker.ajp13.port=8009
worker.ajp13.host=localhost
worker.ajp13.type=ajp13
worker.ajp13.lbfactor=1
這樣就完成了均衡負(fù)載的配置。
步驟4：
配置tomcat6
<Engine name="Standalone" defaultHost="localhost" jvmRoute="tomcat2">
再配置tomcat6集群的session復(fù)制。打開tomcat6，conf目錄下的server.xml文件。把集群配置的注釋去掉。變成
<Cluster className="org.apache.catalina.ha.tcp.SimpleTcpCluster"
channelSendOptions="8">
<Manager className="org.apache.catalina.ha.session.DeltaManager"
expireSessionsOnShutdown="false"
notifyListenersOnReplication="true"/>
<Channel className="org.apache.catalina.tribes.group.GroupChannel">
<Membership className="org.apache.catalina.tribes.membership.McastService"
address="228.0.0.4"
port="45564"
frequency="500"
dropTime="3000"/>
<Receiver className="org.apache.catalina.tribes.transport.nio.NioReceiver"
address="auto"
port="4000"
autoBind="100"
selectorTimeout="5000"
maxThreads="6"/>
<Sender className="org.apache.catalina.tribes.transport.ReplicationTransmitter">
<Transport className="org.apache.catalina.tribes.transport.nio.PooledParallelSender"/>
</Sender>
<Interceptor className="org.apache.catalina.tribes.group.interceptors.TcpFailureDetector"/>
<Interceptor className="org.apache.catalina.tribes.group.interceptors.MessageDispatch15Interceptor"/>
</Channel>
<Valve className="org.apache.catalina.ha.tcp.ReplicationValve"
filter=""/>
<Valve className="org.apache.catalina.ha.session.JvmRouteBinderValve"/>
<Deployer className="org.apache.catalina.ha.deploy.FarmWarDeployer"
tempDir="/tmp/war-temp/"
deployDir="/tmp/war-deploy/"
watchDir="/tmp/war-listen/"
watchEnabled="false"/>
<ClusterListener className="org.apache.catalina.ha.session.JvmRouteSessionIDBinderListener"/>
<ClusterListener className="org.apache.catalina.ha.session.ClusterSessionListener"/>
</Cluster>
步驟5：
建立一個頁面index.jsp：
/*<%
System.out.println("===========================");
%>
*/
<%@ 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 屬性設(shè)置
String dataName = request.getParameter("dataName");
if (dataName != null && dataName.length() > 0) {
String dataValue = request.getParameter("dataValue");
session.setAttribute(dataName, dataValue);
}
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">
名稱:<input type=text size=20 name="dataName">
<br>
值:<input type=text size=20 name="dataValue">
<br>
<input type=submit>
</form>
</body>
</html>
其web.xml配置
<distributable/>
步驟6：
最后使用jmeter運(yùn)行一下簡單測試，設(shè)置40個并發(fā)用戶，測試的IP地址是192.168.10.66（apache）、192.168.10.66（tomcat2）、192.168.10.55（tomcat1）其中tomcat2是有線接入，tomcat2是無線接入。測試頁面為/lzj1/index.jsp。
可以看看結(jié)果：
tomcat1：
Thread Name: 線程組 1-1
Sample Start: 2008-07-13 22:32:42 CST
Load time: 2532
Latency: 2532
Size in bytes: 401
Sample Count: 1
Error Count: 0
Response code: 200
Response message: OK
Response headers:
HTTP/1.1 200 OK
Date: Sun, 13 Jul 2008 14:32:42 GMT
Server: Apache/2.2.9 (Win32) mod_jk/1.2.26
Set-Cookie: JSESSIONID=6A15C0175A2E1EC8E0930FAF0C28ADC9.tomcat1; Path=/lzj1
tomcat2：
Thread Name: 線程組 1-3
Sample Start: 2008-07-13 22:32:44 CST
Load time: 4
Latency: 4
Size in bytes: 401
Sample Count: 1
Error Count: 0
Response code: 200
Response message: OK
Response headers:
HTTP/1.1 200 OK
Date: Sun, 13 Jul 2008 14:32:44 GMT
Server: Apache/2.2.9 (Win32) mod_jk/1.2.26
Set-Cookie: JSESSIONID=2FF347B788690651E7DADE1A040EE94C.tomcat2; Path=/lzj1
可以從結(jié)果看到檢測到的服務(wù)器是Apache/2.2.9 (Win32) ，使用了mod_jk/1.2.26，并且tomcat1的反應(yīng)時間明顯慢于tomcat2，這是由于這里的tomcat1的網(wǎng)絡(luò)是使用的是無線接入的緣故。
