httpd+tomcat负载均衡

Windows Apache + Tomcat 负载均衡

环境准备

jdk 1.6

apache 2.2.* （解压版）

tomcat 6,7,8 （解压版）

设置java环境变量： JAVA_HOME='到bin目录之前的路径，不要有符号结尾'; PATH 前追加 '%JAVA_HOME%\bin;'解压版tomcat会用到这两个环境变量
[tomcat下载](http://tomcat.apache.org)选择 Deployer 版本 zip 下载， 解压后直接 运行 bin\startup.bat运行
[apache下载](http://httpd.apache.org/download.cgi)  apache(httpd)官方不提供windows版下载
可以网上查找 解压版本

apache + 1个 tomcat运行

apache整合tomcat必须要有Tomcat Connectors (mod_jk) 的支持 在tomcat官网Tomcat Connectors处下载 jakarta-tomcat-connectors-jk2.0.2-win32-apache1.3.27.zip 解压后将 mod_jk.so 文件拷贝到 apache modules目录下
