前段时间写了一篇关于apache+tomcat单节点多实例的安装部署方法，最近公司做项目又要求做多节点单实例的安装方法，由于配置容易出错，所以写博客记录一下方法，其实也没什么可配置的，就是把单节点多实例的配置文件修改一下就行。

部署环境： Windows Server 2008 64位

jdk-1.6.0_43 64位

ip设置:

apache 192.168.1.21

tomcat1 192.168.1.22

tomcat2 192.168.1.23

一、Apache 配置：

Apache安装好后，主要是修改conf目录下的配置文件:

A、新建三个文件

1. workers.properties

#server 列表

worker.list=controller,tomcat1,tomcat2

#========tomcat1========

worker.tomcat1.port=8010

worker.tomcat1.host=192.168.1.22

worker.tomcat1.type=ajp13

worker.tomcat1.lbfactor=1

#========tomcat2========

worker.tomcat2.port=8010

worker.tomcat2.host=192.168.1.23

worker.tomcat2.type=ajp13

worker.tomcat2.lbfactor=1

#========controller,负载均衡控制器========

worker.controller.type=lb

worker.retries=3

worker.controller.balance_workers=tomcat1,tomcat2

#worker.controller.sticky_session=false

worker.controller.sticky_session=1

#worker.controller.sticky_session_force=1

worker.jkstatus.type=status

worker.list=jkstatus

2.uriworkermap.properties （比较灵活，带“#”可不写）

/*=controller

#所有包含jkstatus请求的都由status这个 server处理

/jkstatus=jkstatus

#这里的"!”是“非”的意思。

#/*.gif=controller

#/*.jpg=controller

#/*.png=controller

#/*.css=controller

#/*.js=controller

#/*.htm=controller

#/*.html=controller

3. mod_jk.conf

LoadModule jk_module modules/mod_jk-1.2.31-httpd-2.2.3.so ##modus目录下需要有这个文件

JkWorkersFile conf/workers.properties

JkMountFile conf/uriworkermap.properties

#指定那些请求交给tomcat处理,"controller"为在workers.propertise里指定的负载分配控制器名

JkMount /*.jsp controller

JkLogLevel warn

B、修改httpd.conf（修改前最好先备份）

在最后一行加上：

include "C:\Program Files (x86)\Apache Software Foundation\Apache2.2\conf\mod_jk.conf"

注：这里的是apache安装目录

总体来说apache配置主要是配置文件的修改，ip和端口等配置

二、Tomcat配置

两个tomcat的配置文件一样，只有一条需修改，下面贴出tomcat的配置文件：

<?xml version='1.0' encoding='utf-8'?>

其中 tomcat2的这一条 <Engine name="Catalina" defaultHost="localhost" jvmRoute="tomcat1" >

修改为<Engine name="Catalina" defaultHost="localhost" jvmRoute="tomcat2" >，其余没变化

由于后端数据库用的是oracle，所以在tomcat解析完war包后，还要配置oracle的连接地址，目录为“tomcat目录\webapps\“war包文件夹”\WEB-INF\classe\config下的jdbc.properties文件

至此，apache+tomcat最基本的安装配置就到此结束
