RHEL5 Apache+Tomcat整合，同时支持jsp与php

配置环境：
OS: RHEL5 with kernel 2.6.18-8.1.1.el5
httpd-2.2.3-6.el5.i386.rpm
apache-tomcat-6.0.14.tar.gz
jdk-6u3-linux-i586.bin
mod_jk-1.2.23-apache-2.2.x-linux-i686.so
官方宣称mod_jk-1.2.26-httpd-2.2.6.so支持Apache 2.2.x及2.2.6以后的版本，但经实验，1.2.26的mod_jk在RHEL5中会报错。

一、安装配置jdk及tomcat
1、安装jdk及tomcat
[root@wardking ~]# tar zxvf apache-tomcat-6.0.14.tar.gz -C /usr/local/
[root@wardking ~]# mv jdk-6u3-linux-i586.bin /usr/local/
[root@wardking ~]# cd /usr/local
[root@wardking local]# chmod a+x jdk-6u3-linux-i586.bin
[root@wardking local]# ./jdk-6u3-linux-i586.bin

2、配置环境变量
[root@wardking ~]# ln -sf /usr/local/apache-tomcat-6.0.14 /usr/local/tomcat
[root@wardking ~]# ln -sf /usr/local/jdk1.6.0_03 /usr/local/jdk6
[root@wardking ~]# ln -sf /usr/local/jdk6/bin/java /usr/bin/
[root@wardking ~]# ln -sf /usr/local/tomcat/bin/startup.sh /usr/bin/tomcat-up
[root@wardking ~]# ln -sf /usr/local/tomcat/bin/shutdown.sh /usr/bin/tomcat-down
添加一个名为“michael”的管理员用户
[root@wardking ~]# vi /usr/local/tomcat/conf/tomcat-users.xml
<user username="michael" password="123456" roles="manager,admin"/>
设置环境变量
[root@wardking ~]# vi /etc/profile
JAVA_HOME=/usr/local/jdk6
CATALINA_HOME=/usr/local/tomcat
CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar:$CATALINA_HOME/lib/servlet-api.jar
PATH=$JAVA_HOME/bin:$PATH
export JAVA_HOME CATALINA_HOME CLASSPATH PATH
[root@wardking ~]# source /etc/profile
3、测试tomcat服务
[root@wardking ~]# /usr/bin/tomcat-up
或者直接执行
/usr/local/tomcat/bin/startup.sh
检查tomcat是否启动
[root@wardking ~]# netstat -anp | grep 8080
在浏览器里访问http://localhost:8080/，可以看到tomcat的网页界面，并可以使用
用户“michael”登陆管理
停止tomcat服务
[root@wardking ~]# tomcat-down
二、连接tomcat到apache
1、安装mod_jk模块
[root@wardking ~]# cp mod_jk-1.2.23-apache-2.2.x-linux-i686.so /etc/httpd/modules/
2、修改apache配置文件
[root@wardking ~]# vi /etc/httpd/conf.d/mod_jk.conf
LoadModule jk_module modules/mod_jk-1.2.23-apache-2.2.x-linux-i686.so
JkWorkersFile "/etc/httpd/conf/workers.properties"
JkShmFile /var/log/httpd/mod_jk.shm
JkLogFile "/var/log/httpd/mod_jk.log"
JkLogLevel info
JkMount /*/servlet/* ajp13
JkMount /*.jsp ajp13
JkMount /*.do ajp13
AddType application/x-jsp .jsp
3、添加tomcat配置文件
[root@wardking ~]# vi /etc/httpd/conf/workers.properties
[shm]
file=/etc/httpd/logs/shm.file
size=1048576
[channel.socket:localhost:8009]
tomcatId=localhost:8009
[uri:/jsp-examples/*]
workers.tomcat_home=/usr/local/tomcat
workers.java_home=/usr/local/jdk6
ps=\
worker.list=ajp13
worker.ajp13.port=8009
worker.ajp13.host=localhost
worker.ajp13.type=ajp13
worker.ajp13.lbfactor=1
4、设置tomcat主目录
[root@wardking ~]# vi /usr/local/tomcat/conf/server.xml
       <Host name="localhost"   appBase="/var/www/html/"
             unpackWARs="true" autoDeploy="true"
             xmlValidation="false" xmlNamespaceAware="false">
         <Context path="" docBase="" debug="0"/>
5、确认apache、tomcat启动

[root@wardking ~]# httpd -t
[root@wardking ~]# service httpd restart
[root@wardking ~]# /usr/bin/tomcat-up
6、分别测试访问php和jsp网页
[root@wardking ~]# vi /var/www/html/showtime.jsp
<%@page language="java" import="java.util.*"%>
Now Time is : <% out.println(new Date()); %>
[root@wardking ~]# echo '<?php phpinfo(); ?>' > phpinfo.php
在浏览器中访问http://localhost/showtime.jsp，应在网页中显示系统时间
访问http://localhost/phpinfo.php，显示php及服务器相关配置信息

另一种整合办法，在httpd.conf中使用反向代理：
ProxyPass /images !
ProxyPass /icons !
ProxyPass / ajp://127.0.0.1:8009/
ProxyPassReverse / ajp://127.0.0.1:8009/
