Apache+Tomcat集群

 

 

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
