windows 上实现Apache 负载均衡 +tomcat群集 （二）

Tomcat集群的配置：

1.       下载 tomcat 的软件包：下载解压版本

Binary Distributions

・         Core: o    zip ( pgp , md5 )

下载地址：

http://apache.freelamp.com/tomcat/tomcat-6/v6.0.20/bin/apache-tomcat-6.0.20.zip

 

解压 tomcat 到 c 盘根目录，重命名为 tomcat1 ，然后复制 tomcat1 为 tomcat2.

 

修改 server.xml 配置文件

 

Tomcat1 中修改的部分：

1.<Server port="9005" shutdown="SHUTDOWN">

 

 

 2. <Connector port="9080" protocol="HTTP/1.1"

               connectionTimeout="20000"

               redirectPort="8443" />

 

1.       <Connector port="9009" protocol="AJP/1.3" redirectPort="8443" />

 

 

4. <Host name="localhost"  appBase="webapps"

            unpackWARs="true" autoDeploy="true"

            xmlValidation="false" xmlNamespaceAware="false">

----------------------------------- 添加的部分 -----------------------------------

集群测试

在 2 个 tomcat 里面添加网页

 

 

Tomcat1 上的 \webapps\ROOT\index.html 内容如下：

<html>

<head><title>Tomcat 群集 1</title></head>

<body>

<center>Tomcat 1 号机在 tomcatA 机上

</center>

</body>

</html>

 

Tomcat2 上的 webapps\ROOT\index.html 内容如下：

<html>

<head><title>Tomcat  群集 2</title></head>

<body>

<center>Tomcat 2 号机在 TomcatB 机上

</center>

</body>

</html>

 

 

启动 Tomcat1 和 Tomcat2 ，再启动 Apache
