Apache+Tomcat集群配置

hq8501

　　准备环境
　　下载
　　Apache HTTP Server http://labs.mop.com/apache-mirror/httpd/binaries/win32/ 下载httpd-2.2.22-win32-x86-no_ssl.msi
　　JK http://www.apache.org/dist/tomcat/tomcat-connectors/jk/binaries/windows/ 下载tomcat-connectors-1.2.37-windows-i386-httpd-2.2.x.zip
　　Tomcat http://tomcat.apache.org/download-70.cgi
　　安装
安装Apache HTTP Server，如果没有其他的http服务器(如iis)则应该可以成功安装，端口即为80，能够访问http://localhost/ 说明安装成功。
　　

安装Tomcat7，下载tomcat7解压缩为4个tomcat文件，分别命名tomcat1、tomcat2、tomcat3、tomcat4.
　　tomcat6.X与tomcat7.X集群通用。

配置
　　Apache配置
1、修改httpd.conf
在Apache安装目录下找到conf目录下的httpd.conf，在文件的最后一行添加
include conf/mod_jk.conf

2、新建mod_jk.conf文件，内容如下：

LoadModule jk_module modules/mod_jk.so
JkWorkersFile conf/workers.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 /* controller

3、将下载的JK插件解压拷贝mod_jk.so,复制到Apache安装目录的modules目录下。

4、在apache的安装目录conf下新建并编辑workers.properties文件，内容如下：
　　#server
worker.list = controller

#========tomcat1========
worker.tomcat1.port=8719
worker.tomcat1.host=localhost
worker.tomcat1.type=ajp13
worker.tomcat1.lbfactor = 1
worker.tomcat1.redirect=tomcat2

#========tomcat2========
worker.tomcat2.port=8729
worker.tomcat2.host=localhost
worker.tomcat2.type=ajp13
worker.tomcat2.lbfactor = 1
worker.tomcat2.redirect=tomcat1
#worker.tomcat2.activation=disabled

#========tomcat3========
worker.tomcat3.port=8739
worker.tomcat3.host=localhost
worker.tomcat3.type=ajp13
worker.tomcat3.lbfactor = 1
worker.tomcat3.redirect=tomcat4

#========tomcat4========
worker.tomcat4.port=8749
worker.tomcat4.host=localhost
worker.tomcat4.type=ajp13
worker.tomcat4.lbfactor = 1
worker.tomcat4.redirect=tomcat3
#worker.tomcat4.activation=disabled 

#========controller,负载均衡控制器========
worker.controller.type=lb
worker.controller.balanced_workers=tomcat1,tomcat2,tomcat3,tomcat4
worker.controller.sticky_session=false
#worker.controller.sticky_session_force=1
#worker.controller.sticky_session=1
　　PS:#worker.tomcat4.activation=disabled  表示tomcat是否激活

注意AJP13的connector的poat和jvmRoute名称和workers.properties中配置对应。228.0.0.4和228.0.0.5表示tomcat的群组

基于windows环境搭建完毕，参考文档如下
