2 Tomcat & apache 整合的意义
尽管Tomcat可以作为独立的Web服务器运行，但是Tomcat的Web功能远远没有Apache强大，所以在实际应用中通过 mod_jk2 连接器将 Apache 以及 Tomcat 整合。整合之后，Apache 负责处理静态页面，而 Tomcat 则负责处理动态页面。
3 软件准备
软件
说明
操作系统
Red Hat Enterprise Linux AS release 4 (Nahant Update 8) x86_64 （所有组件默认全部安装）
Tomcat版本
Tomcat5.5.35
apache
Apache/2.2.3（系统自带）

连接器
mod_jk-1.2.23-apache-2.2.x-linux-i686.so
http://archive.apache.org/dist/tomcat/tomcat-connectors/jk/binaries/linux/jk-1.2.23/mod_jk-1.2.23-apache-2.2.x-linux-i686.so
jk2模块通过httpd把jsp等的web请求转发给tomcat，实现不同的文件由不同的解释器解析。注意不同的apache版本要选择不同的连接器版本。
如果第一步的二进制文件有问题，可以先编译一下模板
　Jdk版本
"1.6.0_31"
Tomcat 需要根据环境变量设置找到 JDK的安装目录，否则不能正常启动和停止，

4 连接器安装与配置

4.1 JK 安装 （整合apache tomcat）

# tar zxvf tomcat-connectors-1.2.32-src.tar.gz
#cd tomcat-connectors-1.2.32-src/native
# ./configure --with-apxs=/usr/sbin/apxs -with-java-home=/usr/local/java
# make && make install
4.2 将/etc/httpd/conf/ workers.properties /etc/httpd/conf.d/ jk2.conf 两个文件按如下内容配置
配置文件/etc/httpd/conf.d/ jk2.conf，添加如下记录
cat workers.properties
worker.list=node1
workers.java_home=/usr/local/java
worker.node1.type=ajp13
worker.node1.host=localhost
worker.node1.port=8009

配置/etc/httpd/conf/ workers.properties，添加如下记录
cat jk.conf
# Load mod_jk module
# Update this path to match your modules location
LoadModule jk_module modules/mod_jk.so
# Where to find workers.properties
# Update this path to match your conf directory location (put workers.properties next to httpd.conf)
JkWorkersFile /etc/httpd/conf/workers.properties

# Where to put jk logs
# Update this path to match your logs directory location (put mod_jk.log next to access_log)
JkLogFile /var/log/httpd/mod_jk.log

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

# Select the log format
JkLogStampFormat "[%a %b %d %H:%M:%S %Y] "

# JkOptions indicate to send SSL KEY SIZE,
JkOptions +ForwardKeySize +ForwardURICompat -ForwardDirectories

# JkRequestLogFormat set the request format
JkRequestLogFormat "%w %V %T"

# Send everything for context /examples to worker named worker1 (ajp13)
#JkMount /examples/* worker1
JkMount /*.jsp node1
4.3 Apache 和 Tomcat发布目录设置
要实现 Apache 和 Tomcat 整合，需要设置 Apache 和 Tomcat 的主目录一致，现定于发布目录是：/opt/app/，配置如下：
4.3.1 Tomcat 配置
在service.xml文件中添加：

4.3.2 Apache配置
DocumentRoot "/opt/app/"
DirectoryIndex index.jsp index.html index.html.var

5 启动程序
[root@localhost conf]# /etc/init.d/httpd restart
Stopping httpd: [ OK ]
Starting httpd: [ OK ]
[root@localhost conf]# /usr/local/tomcat/bin/shutdown.sh
Using CATALINA_BASE: /usr/local/tomcat
Using CATALINA_HOME: /usr/local/tomcat
Using CATALINA_TMPDIR: /usr/local/tomcat/temp
Using JRE_HOME: /usr/jdk
[root@localhost conf]# /usr/local/tomcat/bin/startup.sh
Using CATALINA_BASE: /usr/local/tomcat
Using CATALINA_HOME: /usr/local/tomcat
Using CATALINA_TMPDIR: /usr/local/tomcat/temp
Using JRE_HOME:
5.1 测试
/usr/jdk 最后在主目录/var/www/html 中创建一个名为 test.jsp 的文件，内容如下：
[root@localhost ~]# cd /var/www/html/
[root@localhost html]# vi test.jsp
[root@localhost html]# cat test.jsp
Hello! The time is <%=new java.util.Date() %>
完成之后，可从客户端访问服务器进行测试：http://192.168.1.200/test.jsp，若出现下面的页面，证明
Apache+Tomcat 的整个整合过程成功！
