本文详细介绍如何在CentOS 5.4环境下配置Apache与Tomcat的集成，包括安装必要软件、配置Apache与Tomcat之间的连接，以及设置必要的配置文件等步骤。通过遵循这些步骤，可以实现使用Apache作为前端服务器，而将JSP请求转发给Tomcat进行处理。

系统环境：
system：CentOS release 5.4 (Final)
httpd-2.2.14（/usr/local/apache2）
apache-tomcat-6.0.29（/usr/local/tomcat）
java-1.6.0_14（/usr/local/java6）
tomcat-connectors-1.2.37
下载地址
http://tomcat.apache.org/download-connectors.cgi

tar -xvf tomcat-connectors-1.2.37-src.tar.gz
cd tomcat-connectors-1.2.37-src/native/
./configure --with-apxs=/usr/local/apache2/bin/apxs
make
make install
vi /usr/local/apache2/conf/httpd.conf
1.添加默认页面（index.jsp ，可不添加）
DirectoryIndex index.jsp index.html
2.添加如下文件
LoadModule jk_module          modules/mod_jk.so
Include /usr/local/apache2/conf/extra/mod_jk.conf
(切记在对应的位置，LoadModule和Include放置对应的地方)
[root@localhost htdocs]# vi /usr/local/apache2/conf/extra/mod_jk.conf
JkWorkersFile conf/extra/workers.properties
JkLogFile   logs/mod_jk.log
JkShmFile   logs/jk-runtime-status
JkLogLevel info
JkLogStampFormat "[%a %b %d %H:%M:%S %Y] "
JkOptions +ForwardKeySize +ForwardURICompat -ForwardDirectories
JkRequestLogFormat "%w %V %T"
#Sample JkMounts.   Replace these with the paths you would
#like to mount from your JSP server.
#syntax: JkMount ${URL_DIR}/*.jsp worker_name
JkMount   /images/avatar/*     worker1
JkMount   /*.jsp worker1
JkMount /*.page worker1
JkMount /*.cic worker1
JkMount /func/* worker1
JkMount   /assets/*          worker1
JkMount   /remote/*          worker1
JkMount   /services/*        worker1
JkMount   /homebase/*        worker1
JkMount /skin/*      worker1
JkMount /error/*     worker1
JkMount /lib/*       worker1
JkMount /protected/*       worker1
JkMount /rounded/*       worker1
JkMount /FormOverLogin*       worker1
JkMount /fckeditor/editor/filemanager/connectors/*       worker1
JkMount /upload/image/*       worker1

简要说明：
###JkWorkersFile conf/extra/workers.properties
指出mod_jk模块工作所需要的工作文件workers.properties的位置
###JkLogFile logs/mod_jk.log
放置jk logs的位置
###JkLogLevel info
Set the jk log level [debug/error/info]
###JkLogStampFormat "[%a %b %d %H:%M:%S %Y] "
Select the log format
###JkOptions +ForwardKeySize +ForwardURICompat -ForwardDirectories
JkOptions indicate to send SSL KEY SIZE,
###JkRequestLogFormat "%w %V %T"
JkRequestLogFormat set the request format
###JkMount..xx...worker1
..xx...请求通过ajp13的协议送给Tomcat，让Tomcat来处理

Set the jk log level [debug/error/info]

[root@localhost htdocs]# vi /usr/local/apache2/conf/extra/workers.properties
worker.list=worker1
worker.worker1.port=8009
worker.worker1.host=localhost
worker.worker1.type=ajp13
worker.woker1.lbfactor=1

tomcat修改web路径与apahce保持一致
在<Host></Host>之间添加
<Context path="" docBase="/usr/local/apache2/htdocs/" debug="0" reloadable="true" crossContext="true" />

启动Apache：
#/usr/local/apache2/bin/apachectl start
启动tomcat：
#/usr/local/tomcat/bin/startup.sh start

编写简单jsp界面测试apache是否支持jsp页面（/usr/local/apache2/htdocs）:
index.jsp
<html>
<body>
<h1>JSP Test Page</h1>
<%=new java.util.Date()
%>
</body>
</html>

返回正常（）
JSP Test Page

方法二：
在 /usr/local/apache2/conf/httpd.conf 末尾加入：
<Proxy balancer://localCluster>
BalancerMember ajp://localhost:8009
</Proxy>
RewriteEngine On
ProxyPreserveHost On
RewriteRule ^/$ balancer://localCluster/ [P,L,NC]
RewriteRule ^/(.*)$ balancer://localCluster/$1 [P,L,NC]

然后修改tomcat web路径同上即可！
