在Linux操作系统中Apache与Tomcat的整合

系统环境：Red Hat Enterprise Linux Server release 5 (kernel 2.6.18-8.el5xen)

软件环境：

httpd-2.2.3-6.el5.i386.rpm

apache-tomcat-6.0.14.tar.gz

jdk-6u2-linux-i586.bin

mod_jk-1.2.25-httpd-2.2.4.so

http://www.apache.org/dist/tomcat/tomcat-connectors/jk/binaries/linux/jk-1.2.25/i386/mod_jk-1.2.25-httpd-2.2.4.so

目标功能：

将tomcat整合到apache服务器中，当通过apache访问.jsp文件时自动调用tomcat解释执行。

注：为简单起见，httpd使用RHEL5系统自带的软件包，并基于默认配置。关于LAMP的整合安装请参考其它资料。

一、安装配置jdk及tomcat

1、安装jdk及tomcat

# tar zxvf apache-tomcat-6.0.14.tar.gz -C /usr/local/
# mv jdk-6u2-linux-i586.bin /usr/local/
# cd /usr/local
# chmod a+x jdk-6u2-linux-i586.bin
# ./jdk-6u2-linux-i586.bin

2、配置环境变量

# ln -sf /usr/local/apache-tomcat-6.0.14 /usr/local/tomcat
# ln -sf /usr/local/jdk1.6.0_02 /usr/local/jdk6
# ln -sf /usr/local/jdk6/bin/java /usr/bin/
# ln -sf /usr/local/tomcat/bin/startup.sh /usr/bin/tomcat-up
# ln -sf /usr/local/tomcat/bin/shutdown.sh /usr/bin/tomcat-down
# vi /usr/local/tomcat/conf/tomcat-users.xml    //添加一个名为“zhangsan”的管理员用户
<user username="zhangsan" password="123456" roles="manager,admin"/>
# 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
# logout       //注销后重新登陆，以便环境变量生效

3、测试tomcat服务

# /usr/bin/tomcat-up //或者直接执行/usr/local/tomcat/bin/startup.sh

# netstat -anp | grep :8080 //检查tomcat是否启动

在浏览器里访问http://localhost:8080/，应能看到tomcat的网页界面，并可以使用用户“zhangsan”登陆管理

# tomcat-down //使用关闭脚本可以停止tomcat服务

二、连接tomcat到apache

1、安装mod_jk模块

# cp mod_jk-1.2.25-httpd-2.2.4.so /etc/httpd/modules/ //将模块文件放置到apache的模块目录

2、修改apache配置文件

# cd /etc/httpd/conf/

# cp -pf httpd.conf httpd.conf.bak

# vi httpd.conf

LoadModule jk_module modules/mod_jk-1.2.25-httpd-2.2.4.so

JkWorkersFile "/usr/local/tomcat/conf/workers.properties"

JkLogFile "/usr/local/tomcat/logs/mod_jk2.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

# vi /usr/local/tomcat/conf/workers.properties

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、确认apache、tomcat启动
