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-----------------------------------

 </Host>

 

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
