系統環境：Windows XP SP3 ，jdk1.5.0_05
軟體版本：apache_2.2.11-win32-x86-openssl-0.9.8i.msi apache-tomcat-6.0.16 apache-tomcat-6.0.18
備註：tomcat可以下載壓縮包直接解壓就可以，另外也下載整合了APR（Apache Tomcat Native library 1.1.16）
Apache和Tomcat的整合個人推薦使用AJP的方式，配置簡單，而且現在tomcat官方鼓勵採用這種方式呢！如果想體驗mod_JK的方式，下面也有介紹。
我是在同一臺機器上作的測試，因為我完成了apache的負載均衡以及tomcat6的叢集和session的複製，所以需要修改到的地方可能比較多，先將配置列出如下：
一、AJP方式的配置：
1、 修改apache的httpd.conf
首先要load所需要的so檔案，需要列表如下：
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_http_module modules/mod_proxy_http.so
LoadModule proxy_connect_module modules/mod_proxy_connect.so

ProxyPass /images !
ProxyPass /css !
ProxyPass /js !

<Proxy balancer://cluster/>
BalancerMember ajp://localhost:8009/ route=tomcat1 loadfactor=50
BalancerMember ajp://localhost:9009/ route=tomcat2 loadfactor=50
</Proxy>

開啟虛擬主機
# Virtual hosts
Include conf/extra/httpd-vhosts.conf

httpd-vhosts.conf：
NameVirtualHost *:80
<VirtualHost *:80>
ServerAdmin

[email protected]
DocumentRoot "D:\www\webapps"
ServerName localhost
ServerAlias localhost
ErrorLog "logs/localhost-error.log"
CustomLog "logs/localhost-access.log" common
ProxyRequests Off
ProxyPass / balancer://cluster/ stickysession=JSESSIONID nofailover=On
ProxyPassReverse / balancer://cluster/
#ProxyPassReverse /test balancer://cluster/ test
</VirtualHost>
二、mod_jk方式的配置
1、修改apache的httpd.conf
LoadModule jk_module modules/mod_jk.so
JkWorkersFile "conf\workers.properties"
JkMountFile "conf\uriworkermap.properties"

JkLogFile "logs\mod_jk2.log"
JkShmFile "logs\jk.shm"
JkLogLevel info

workers.properties：
workers.java_home=D:\ jdk1.5.0_05
ps=\
worker.list= status,LBCONTROLLER


# localhost server 1
# ------------------------
worker.s1.port=8009
worker.s1.host=localhost
worker.s1.type=ajp13

# localhost server 2
# ------------------------
worker.s2.port=9009
worker.s2.host=localhost
worker.s2.type=ajp13

worker.LBCONTROLLER.type=lb
worker.retries=3
worker.LBCONTROLLER.balanced_workers=s1,s2
worker.LBCONTROLLER.sticky_session=true

worker.status.type=status

uriworkermap.properties：
/*= LBCONTROLLER
#/*.jsp= LBCONTROLLER
#/*.do= LBCONTROLLER
#/*.action= LBCONTROLLER
#/servlet/*= LBCONTROLLER

/jkstatus=status

!/*.gif= LBCONTROLLER
!/*.jpg= LBCONTROLLER
!/*.png= LBCONTROLLER
!/*.css= LBCONTROLLER
!/*.js= LBCONTROLLER
!/*.htm=DLOG4J
!/*.html=DLOG4J
開啟虛擬主機
# Virtual hosts
Include conf/extra/httpd-vhosts.conf

httpd-vhosts.conf：
NameVirtualHost *:80
<VirtualHost *:80>
ServerAdmin

[email protected]
DocumentRoot "D:\www\webapps"
ServerName localhost
ServerAlias localhost
ErrorLog "logs/localhost-error.log"
CustomLog "logs/localhost-access.log" common
JkMountCopy On
</VirtualHost>

三、修改%TOMCAT_HOME%/conf/server.xml（跟使用AJP和JK方式沒有關係，皆通用）
新增叢集的配置：
<Cluster className="org.apache.catalina.ha.tcp.SimpleTcpCluster" channelSendOptions="6">
<!--
<Manager className="org.apache.catalina.ha.session.BackupManager"
expireSessionsOnShutdown="false"
notifyListenersOnReplication="true"
mapSendOptions="6"/>
-->
<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="5001"
selectorTimeout="100"
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"/>
<Interceptor className="org.apache.catalina.tribes.group.interceptors.ThroughputInterceptor"/>
</Channel>
<Valve className="org.apache.catalina.ha.tcp.ReplicationValve"
filter=".*\.gif;.*\.js;.*\.jpg;.*\.png;.*\.htm;.*\.html;.*\.css;.*\.txt;"/>
<!--
<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>
四、實現session複製
第一步：
Tomcat 6.0.16
<Engine name="Standalone" defaultHost="localhost" jvmRoute="tomcat1">
<!--
<Engine name="Catalina" defaultHost="localhost">
-->
Tomcat 6.0.18
<Engine name="Standalone" defaultHost="localhost" jvmRoute="tomcat2">
<!--
<Engine name="Catalina" defaultHost="localhost">
-->

第二步：
Webapps目錄下的應用程式的web.xm中必須新增
<distributable/> 此應用將與群集伺服器複製Session

因為是在同一臺機器上啟動多個tomcat，所以修改監聽的埠是必不可少的，這裡將我的配置列出如下：
Tomcat 6.0.16
<Connector port="8080" protocol="HTTP/1.1"
connectionTimeout="20000"
redirectPort="8443" acceptCount="5000" maxThreads="2000"/>
<Connector port="8009" protocol="AJP/1.3" redirectPort="8443" />
Tomcat 6.0.18
<Connector port="9080" protocol="HTTP/1.1"
connectionTimeout="20000"
redirectPort="9443" acceptCount="5000" maxThreads="2000"/>
<Connector port="9009" protocol="AJP/1.3" redirectPort="9443" />
配置完成，先啟動所有tomcat伺服器，最後啟動apache2.2伺服器
以上為個人使用過程的總結，具體的效能沒有做測試，所以沒法做比較，如有疑問，可以聯絡QQ：735014642，進行溝通，歡迎指正~~
