windows下tomcat集群配置（两种方法）
两种方法只是在配置上不同原理一样，因为apache2.X后其自身集成了mod_jk功能，相对于1.3版本，不需要再进行繁琐的worker.properties配置，配置过程大幅简化。
一、软件需求
操作系统：Windows XP
JDK：jdk1.6.0_16，下载地址：http://www.oracle.com/technetwork/java/javase/downloads/index.html 。
Apache ：httpd-2.2.17 （一个），下载地址：http://httpd.apache.org/ 。
Tomcat：tomcat-7.0.2 （两个），下载地址：http://tomcat.apache.org/download-70.cgi 。
mod_jk：mod_jk-apache-2.0.55.so （1个），下载地址：http://tomcat.apache.org/download-70.cgi 。
二、环境搭建
安照上篇《windows下apache tomcat整合》中的方法安装jdk/apache/tomcat
三、环境配置（两种配置）

2>httpd.conf(apache/conf)
httpd.conf
1 # 2 # This is the main Apache HTTP server configuration file. It contains the 3 # configuration directives that give the server its instructions. 4 # See <URL:http://httpd.apache.org/docs/2.2> for detailed information. 5 # In particular, see 6 # <URL:http://httpd.apache.org/docs/2.2/mod/directives.html> 7 # for a discussion of each configuration directive. 8 # 9 # Do NOT simply read the instructions in here without understanding 10 # what they do. They're here only as hints or reminders. If you are unsure 11 # consult the online docs. You have been warned. 12 # 13 # Configuration and logfile names: If the filenames you specify for many 14 # of the server's control files begin with "/" (or "drive:/" for Win32), the 15 # server will use that explicit path. If the filenames do *not* begin 16 # with "/", the value of ServerRoot is prepended -- so "logs/foo.log" 17 # with ServerRoot set to "D:/Program Files/Apache Software Foundation/Apache2.2" will be interpreted by the 18 # server as "D:/Program Files/Apache Software Foundation/Apache2.2/logs/foo.log". 19 # 20 # NOTE: Where filenames are specified, you must use forward slashes 21 # instead of backslashes (e.g., "c:/apache" instead of "c:\apache"). 22 # If a drive letter is omitted, the drive on which httpd.exe is located 23 # will be used by default. It is recommended that you always supply 24 # an explicit drive letter in absolute paths to avoid confusion. 25 26 # 27 # ServerRoot: The top of the directory tree under which the server's 28 # configuration, error, and log files are kept. 29 # 30 # Do not add a slash at the end of the directory path. If you point 31 # ServerRoot at a non-local disk, be sure to point the LockFile directive 32 # at a local disk. If you wish to share the same ServerRoot for multiple 33 # httpd daemons, you will need to change at least LockFile and PidFile. 34 # 35 ServerRoot "D:/Program Files/Apache Software Foundation/Apache2.2" 36 37 # 38 # Listen: Allows you to bind Apache to specific IP addresses and/or 39 # ports, instead of the default. See also the <VirtualHost> 40 # directive. 41 # 42 # Change this to Listen on specific IP addresses as shown below to 43 # prevent Apache from glomming onto all bound IP addresses. 44 # 45 #Listen 12.34.56.78:80 46 Listen 80 47 48 # 49 # Dynamic Shared Object (DSO) Support 50 # 51 # To be able to use the functionality of a module which was built as a DSO you 52 # have to place corresponding `LoadModule' lines at this location so the 53 #

以上最后的两个文件及前面有些配置使用该优化tomcat和jdk的，配置完成后的各个配置文件，具体操作步骤如下：
(1)负载均衡
找到Apache安装目录下conf目录中的httpd.conf文件。
在文件最后添加一句：include "D:\webserver\Apache Group\Apache2\conf\mod_jk.conf"(具体路径是你放置的位置而定)
接着在conf目录中新建文件mod_jk.conf并添加下面的内容：
#加载mod_jk Module
LoadModule jk_module modules/mod_jk-apache-2.0.59.so
#指定 workers.properties文件路径
JkWorkersFile conf/workers.properties
#指定哪些请求交给tomcat处理,"controller"为在workers.propertise里指定的负载分配控制器名
JkMount /*.jsp controller
在conf目录下新建workers.properties文件并添加如下内容：
#server
worker.list = controller
#========tomcat1========
worker.tomcat1.port=11009
worker.tomcat1.host=localhost
worker.tomcat1.type=ajp13
worker.tomcat1.lbfactor = 1
#========tomcat2========
worker.tomcat2.port=12009
worker.tomcat2.host=localhost
worker.tomcat2.type=ajp13
worker.tomcat2.lbfactor = 1
#（解释一下AJP13是 Apache JServ Protocol version 1.3）
#========controller,负载均衡控制器========
worker.controller.type=lb
worker.controller.balanced_workers=tomcat1,tomcat2
worker.controller.sticky_session=1
将mod_jk-apache-2.0.59.so 复制到Apache的modules目录中。
接下来配置2个Tomcat
打开tomcat1\conf\ server.xml
将Server port 改为11005：<Server port="11005" shutdown="SHUTDOWN">
将Define Connector port改为11080：<Connector port="11080" maxHttpHeaderSize="8192"
将AJP13 Connector port改为11009：<Connector port="11009" enableLookups="false" redirectPort="8443" protocol="AJP/1.3" />
打开tomcat2\conf\server.xml
将Server port 改为12005：<Server port="12005" shutdown="SHUTDOWN">
将Define Connector port改为12080：<Connector port="12080" maxHttpHeaderSize="8192"
将AJP13 Connector port改为12009：<Connector port="12009" enableLookups="false" redirectPort="8443" protocol="AJP/1.3" />
好了，现在建立一个测试程序
分别在两个Tomcat的webapps中建立test目录，并新建test.jsp文件，内容如下：
<%
System.out.println("test");
%>
启动apache, tomcat1, tomcat2
访问http://localhost:8080/test/test.jsp （或者 http://localhost/test/test.jsp）不断刷新页面，看不到交替输出"test"，你需要换两台机器或者开两个浏览器（即两个会话）这样可以在两个Tomcat的控制台中看到，交替输出"test", 这样就实现了负载均衡，由于没有开启session共享所以一次会话集中到了一个toamcat上多个会话会分配道不同的tomact中。
(2)集群配置
集群除了负载均衡，另一个主要功能是Session Replication。
打开tomcat1\conf\ server.xml将<Cluster>部分的注释去掉。
再打开tomcat2\conf\ server.xml将<Cluster>部分的注释也去掉，并将<Cluster>中<Receiver>的tcpListenPort的值改为4002。以避免与Tomcat1冲突。
分别在2个tomcat的webapps\test中新建WEB-INF目录，在WEB-INF中添加web.xml内容如下：
<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>
主要是添加<distributable/>，distributable元素用来告诉servlet容器，程序将部署在分布式Web容器中。
重新启动tomcat1和tomcat2. 访问http://localhost:8080/test/test2.jsp （或http://localhost/test/test2.jsp）
随意添加key-value, 可以看到两个tomcat交替显示session中的值，各个tomcat的session是同步的。
再来修改tomcat1\conf\server.xml，找到<Engine name="Catalina" defaultHost="localhost">为其添加jvmRoute属性，值为apache的conf\workers.properties中配置的tomcat名字。<Engine name="Catalina" defaultHost="localhost" jvmRoute="tomcat1">
同样修改tomcat2\conf\server.xml的相同部分<Engine name="Catalina" defaultHost="localhost" jvmRoute="tomcat2">jvmRoute是tomcat路由标示，由此区分两台tomcat主机。一次会话，就有一个sessionID，这个sessionID后面会跟上jvmRoute设置的值，这样一次会话，就只会让一个tomcat处理。
重新启动tomcat1, tomcat2
访问http://localhost:8080/test/test2.jsp 可以看到session.getId()的值在原session id后面多了jvmRoute的值。ID 46A5843FF4A1E0A84338225AC02F6430.tomcat1
随意添加key-value，可以看到session信息只在tomcat1中输出。
再打开一个浏览器，并访问http://localhost:8080/test/test2.jsp 其session id可能变为ID 11478E5BE5FE388E4845205B4133A30F.tomcat2
其值也只会在tomcat2中输出。
现在把tomcat1关闭，再次刷新访问tomcat1的那个浏览器，可以看到session信息输出到了tomcat2的控制台中，并且session信息仍然保留着。
2. Apache 2.2以后集成了mod_jk功能，相对于1.3版本，不需要再进行繁琐的worker.properties配置，配置过程大幅简化。
(1)apache的配置
a. 首先，在Apache安装目录下找到conf/httpd.conf文件，以文本编辑器打开。去掉以下文本前的注释符(#)以便让Apache在启动时自动加载代理(proxy)模块。
LoadModule proxy_module modules/mod_proxy.so
LoadModule proxy_ajp_module modules/mod_proxy_ajp.so
LoadModule proxy_balancer_module modules/mod_proxy_balancer.so
LoadModule proxy_connect_module modules/mod_proxy_connect.so
LoadModule proxy_ftp_module modules/mod_proxy_ftp.so
LoadModule proxy_http_module modules/mod_proxy_http.so
b. 向下拉动文档找到节点，在DirectoryIndex index.html后加上index.jsp，这一步只是为了待会配置完tomcat后能看到小猫首页，可以不做。
c. 继续下拉文档找到"Include conf/extra/httpd-vhosts.conf"，去掉前面的注释符。
然后找到conf/extra/httpd-vhosts.conf文件，用文本编辑器打开conf/extra/httpd-vhosts.conf，配置虚拟站点，在最下面加上
<VirtualHost *:80> ServerAdmin 管理员邮箱 ServerName localhost（没有可用IP地址代替） ServerAlias localhost ProxyPass / balancer://cluster/ stickysession=jsessionid nofailover=On ProxyPassReverse / balancer://cluster/ ErrorLog "logs/lbtest-error.log" CustomLog "logs/lbtest-access.log" common </VirtualHost>
d. 这里balancer://是告诉Apache需要进行负载均衡的代理，后面的cluster是集群名，可以随意取，两个日志引擎ErrorLog负责记录错误，CustomLog负责记录所有的http访问以及返回状态，日志名可以自己取，笔者取为lbtest。httpd-vhosts.conf配置完毕，回到httpd.conf，在文档最下面加上
ProxyRequests Off <proxy balancer://cluster> BalancerMember ajp://127.0.0.1:8009 loadfactor=1 route=jvm1 BalancerMember ajp://127.0.0.1:9009 loadfactor=1 route=jvm2 </proxy>
ProxyRequests Off 是告诉Apache需要使用反向代理(利用Apache进行负载均衡必须使用反向代理，用于配置工作在tomcat集群中的所有节点，这里的"cluster"必须与上面的集群名保持一致。
Apache通过ajp协议与tomcat进行通信，ip地址和端口唯一确定了tomcat节点和配置的ajp接受端口。loadfactor是负载因子，Apache会按负载因子的比例向后端tomcat节点转发请求，负载因子越大，对应的tomcat服务器就会处理越多的请求，如两个tomcat都是1，Apache就按1：1的比例转发，如果是2和1就按2：1的比例转发。route参数对应后续tomcat配置中的引擎路径(jvmRoute)。
重启Apache服务，如果此时访问http://localhost/将会返回503错误，打开刚才配置的错误日志logs/lbtest-error.log，可以看到错误原因是因为后台服务器没有响应，因为此时tomcat尚未配置和启动。
(2)tomcat配置
如果仅仅为了配置一个可用的集群，Tomcat的配置将会非常简单。分别打开t1和t2的server.xml配置文件，对于t1，尽量采用默认的设置，而对t2作较大改动以避免与t1冲突。如果t2和t1不在同一台服务器上运行，对于端口就不需做改动。
a. 首先是配置关闭端口，找到，t1不变，把t2改为9005。
b. 下面配置Connector的端口，找到non-SSL HTTP/1.1 Connector，即tomcat单独工作时的默认Connector，保留t1默认配置，在8080端口侦听，而把t2设置为在9080端口侦听。
c. 往下找到AJP 1.3 Connector，<Connector port="8009" protocol="AJP/1.3" redirectPort="8443" />，这是tomcat接收从Apache过来的ajp连接请求时使用的端口，保留t1默认设置，把t2端口改为9009。注意，这里的端口对应Apache httpd.conf中BalancerMember中配置的ajp连接端口。
d. 继续向下配置引擎，找到<Engine name="Catalina" defaultHost="localhost">，去掉这段或改为注释，把上方紧挨的<Engine name="Catalina" defaultHost="localhost" jvmRoute="jvm1">注释符去掉，对于t2，去掉注释符并把jvm1改为jvm2。这里的jvmRoute对应Apache httpd.conf中BalancerMember中配置的route参数。
e. 向下找到<Cluster className="org.apache.catalina.ha.tcp.SimpleTcpCluster"/>，打开注释，这里的配置是为了可以在集群中的所有tomcat节点间共享会话（Session）。如果仅仅为了获得一个可用的tomcat集群，Cluster只需要这么配置就可以了，对于更多的Cluster配置笔者将另文解释。
server.xml的配置修改完毕，下一步需要对具体的应用进行配置。在webapps目录下新建test目录，在test目录下新建test.jsp文件，代码如下：
test.jsp
1 ?<%@ page contentType="text/html; charset=GBK" %> 2 <%@ page import="java.util.*" %> 3 <html> 4 <head> 5 <title>Cluster App Test</title> 6 </head> 7 <body> 8 Server Info: 9 <% out.println(request.getLocalAddr() + " : " + request.getLocalPort()+"<br>");%> 10 <% out.println("<br> ID " + session.getId()+"<br>"); 11 String dataName = request.getParameter("dataName"); 12 if (dataName != null && dataName.length() > 0) { 13 String dataValue = request.getParameter("dataValue"); 14 session.setAttribute(dataName, dataValue); 15 } 16 out.print("<b>Session 列表</b>"); 17 Enumeration e = session.getAttributeNames(); 18 while (e.hasMoreElements()) { 19 String name = (String)e.nextElement(); 20 String value = session.getAttribute(name).toString(); 21 out.println( name + " = " + value+"<br>"); 22 System.out.println( name + " = " + value); 23 } 24 %> 25 <form action="test.jsp" method="POST"> 26 名称:<input type=text size=20 name="dataName"><br/> 27 值:<input type=text size=20 name="dataValue"><br/> 28 <input type=submit/> 29 </form> 30 </body> 31 </html>
f. 在test目录下继续新建WEB-INF目录和web.xml，在<web-app>节点下加入<distributable />，这一步非常重要，是为了通知tomcat服务器，当前应用需要在集群中的所有节点间实现Session共享。如果tomcat中的所有应用都需要Session共享，也可以把conf/context.xml中的<Context>改为<Context distributable="true">，这样就不需对所有应用的web.xml再进行单独配置（修改需要Session复制的应用中WEB-INF/web.xml文件，在文件中的<web-app>标签中增加：<distributable/>在应用的web.xml中增加上述配置后，就表示该应用需要进行Session复制）。
启动t1，待t1启动完成后再启动t2。再次访问http://localhost，可以看到小猫页面。访问http://localhost/test/test.jsp。可以看到包括服务器地址，端口，sessionid等信息在内的页面。
注意这里的sessionid，与平常的sessionid相比多了小数点和后面的部分，这里的jvm1即处理当前请求tomcat服务器的jvmRoute，通过这里可以知道是集群中的哪一个服务器处理了当前请求。在文本框中输入名称和值，点击按钮，信息就保存到了Session中，并且显示到页面上。不断点击按钮，可以发现输入的信息并未丢失，而且sessionid小数点之前的部分保持不变，而小数点后面的字符不停的变化，表明是由不同的tomcat服务器处理了这些请求。这样就实现了负载均衡，并且集群中的不同节点间可以实现会话的共享。此时如果停止一个tomcat服务器t2，Apache将会自动把后续请求转发到集群中的其他服务器即t1。重启t2后，Apache会自动侦测到t2的状态为可用，然后会继续在t1和t2间进行负载均衡。
如果需要向集群中增加节点，首先需要对tomcat作类似配置，然后修改Apache httpd.conf，增加BalancerMember，指向新增的tomcat即可。
