Tomcat与HTTP服务器集成的原理
　　
　　Tomcat服务器通过Connector连接器组件与客户程序建立连接，Connector组件负责接收客户的请求，以及把Tomcat服务器的响应结果发送给客户。默认情况下，Tomcat在server.xml中配置了两种连接器：
　　
　　<!-- Define a non-SSL Coyote HTTP/1.1
　　Connector on port 8080 -->
　　<Connector port="8080"
　　maxThreads="150"
　　minSpareThreads="25"
　　maxSpareThreads="75"
　　enableLookups="false"
　　redirectPort="8443"
　　acceptCount="100"
　　debug="0"
　　connectionTimeout="20000"
　　disableUploadTimeout="true" />
　　
　　<!-- Define a Coyote/JK2 AJP 1.3
　　Connector on port 8009 -->
　　<Connector port="8009"
　　enableLookups="false"
　　redirectPort="8443" debug="0"
　　protocol="AJP/1.3" />
　　
　　第一个连接器监听8080端口，负责建立HTTP连接。在通过浏览器访问Tomcat服务器的Web应用时，使用的就是这个连接器。
　　
　　第二个连接器监听8009端口，负责和其他的HTTP服务器建立连接。在把Tomcat与其他HTTP服务器集成时，就需要用到这个连接器。
　　
　　Web客户访问Tomcat服务器上JSP组件的两种方式如图

 

 

快速配置JK连接器连接 APACHE 和tomcat

workers.properties 是JK连结器接口的命令配置文件
一个实例workers.properties
使用ajp13 连结Apache webserver和 Tomcat engine

workers.properties如下：

  # Define 1 real worker using ajp13
  worker.list=worker1
  # Set properties for worker1 (ajp13)
  worker.worker1.type=ajp13
  worker.worker1.host=localhost
  worker.worker1.port=8009

 
你必须有mod_jk.so(unix+liunx)下 windows下面是mod_jk.dll(早期版本)  现在的版本也是.so结尾的了 应为apache
windows版本2.0以上都是.so文件的结尾

如下官方的版本说明(下载地址)

http://www.apache.org/dist/tomcat/tomcat-connectors/jk/binaries/win32/jk-1.2.23/
Apache Tomcat JK 1.2.23 for WIN32

Here you'll find the binaries for IIS, Apache and Sun ONE Web Servers.

mod_jk-apache-1.3.37.so is for Apache 1.3, and works with Apache 1.3.37 and later. Rename to mod_jk.so before putting it in your Apache2/modules directory.
mod_jk-apache-2.0.59.so is for Apache 2.0, and works with Apache 2.0.59 and later. Rename to mod_jk.so before putting it in your Apache2/modules directory. （这个是我现在用的版本 ，配置成功 我的APACHE 是apache_2.0.55-win32-x86-no_ssl.msi)
mod_jk-apache-2.2.4.so is for Apache 2.2, and works with Apache 2.2.4 and later. Rename to mod_jk.so before putting it in your Apache2/modules directory.
isapi_redirect.dll is for IIS 5 and later Web Server.
jk_symbols.zip contans debug (.pdb) information for all modules.

 Unix 的目录结构:

/usr/lib/apache/
/usr/lib/apache2/
/usr/local/apache/libexec/

一般Windows下的目录结构 :

C:\Program Files\Apache Group\Apache\modules\
C:\Program Files\Apache Group\Apache2\modules\

修改http.conf

常见Unix下目录结构:

/etc/httpd/conf/
/etc/httpd2/conf/
/usr/local/apache/conf/

Windows常见目录结构 :

C:\Program Files\Apache Group\Apache\conf\
C:\Program Files\Apache Group\Apache2\conf\

在http.conf最后面加上

  # Load mod_jk module
  # Update this path to match your modules location
  LoadModule    jk_module  libexec/mod_jk.so
  # Declare the module for <IfModule directive> ( 在apache 2.0以上不要加载了)
  AddModule     mod_jk.c
  # 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 shared memory
  # Update this path to match your local state directory or logs directory
  JkShmFile     /var/log/httpd/mod_jk.shm
  # 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 timestamp log format
  JkLogStampFormat "[%a %b %d %H:%M:%S %Y] "
  # Send everything for context /examples to worker named worker1 (ajp13)
  JkMount  /examples/**//* worker1
