apache tomcat 集群

1.下载所需的文件

apache

http://labs.renren.com/apache-mirror/httpd/binaries/win32/httpd-2.2.20-win32-x86-no_ssl.msi

tomcat

http://labs.renren.com/apache-mirror/tomcat/tomcat-6/v6.0.33/bin/apache-tomcat-6.0.33.zip

connectors

http://labs.renren.com/apache-mirror/tomcat/tomcat-connectors/jk/binaries/windows/tomcat-connectors-1.2.32-windows-i386-httpd-2.2.x.zip

2.例子安装目录

tomcatA

F:\cluster\tomcatA

tomcatB

F:\cluster\tomcatB

apachex

F:\cluster\Apache2.2

connectors放到F:\cluster\Apache2.2\modules

3.修改F:\cluster\Apache2.2\conf\httpd.conf,添加

include "F:\cluster\Apache2.2\conf\mod_jk.conf"

4.新建F:\cluster\Apache2.2\conf\mod_jk.conf,内容如下

#加载mod_jk Module

LoadModule jk_module modules/mod_jk.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

5.新建workers.properties,内容如下

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

#========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

6.修改两个tomcat的server.xml,端口部分为了简便,保留tomcatA为默认端口,tomcatB的端口加1000,修改F:\cluster\tomcatA\conf\server.xml

engine最后添加jvmRoute="tomcatB",修改后:

engine标签下添加

<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="192.168.1.105"
                        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>

tomcatB的server.xml需要修改的部分:

Server port="9005"

<Connector port="9080" protocol="HTTP/1.1"

connectionTimeout="20000"

redirectPort="8443" />

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

channelSendOptions="8">

<Manager className="org.apache.catalina.ha.session.DeltaManager"

expireSessionsOnShutdown="false"

notifyListenersOnReplication="true"/>

<!--

<Membership className="org.apache.catalina.tribes.membership.McastService"

address="192.168.1.105"

port="45564"

frequency="500"

dropTime="3000"/>

-->

<Receiver className="org.apache.catalina.tribes.transport.nio.NioReceiver"

address="auto"

port="5000"

autoBind="100"

selectorTimeout="5000"

maxThreads="6"/>

</Sender>

</Channel>

<Valve className="org.apache.catalina.ha.tcp.ReplicationValve"

filter=""/>

<Deployer className="org.apache.catalina.ha.deploy.FarmWarDeployer"

tempDir="/tmp/war-temp/"

deployDir="/tmp/war-deploy/"

watchDir="/tmp/war-listen/"

watchEnabled="false"/>

</Cluster>

7.放入测试文件,F:\cluster\tomcatA\webapps\test\test.jsp,F:\cluster\tomcatB\webapps\test\test.jsp

<% 
   System.out.println(new java.util.Date().toLocaleString());
   out.println(new java.util.Date().toLocaleString());
   out.println(session.getId());
%>

新建F:\cluster\tomcatA\webapps\test\WEB-INF\web.xml,F:\cluster\tomcatB\webapps\test\WEB-INF\web.xml

<?xml version="1.0" encoding="UTF-8"?>

<web-app 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"
   version="2.5"> 

  <display-name>Tomcat Documentation</display-name>
  <description>
     Tomcat Documentation.
  </description>
  
  <distributable/>
</web-app>

注意web.xml的<distributable/>

8.搞定,测试http://localhost/test/test.jsp可以看到两个tomcat都可以正常工作
