apache+多tomcat集群配置过程记录
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 name="Catalina" defaultHost="localhost" jvmRoute="tomcatB">
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" />
<Connector port="9009" protocol="AJP/1.3" redirectPort="8443" />
<Engine name="Catalina" defaultHost="localhost" jvmRoute="tomcatB">
<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="5000"
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>
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
