(5)分别测试每个tomcat的启动是否正常
http://192.168.0.1:7080
http://192.168.0.2:8888
http://192.168.0.4:9999
(三)负载均衡配置过程
(1)在那台要安装apache的服务器上安装apache2.0.55,我的安装路径为默认C:\Program Files\Apache Group\Apache2
(2)安装后测试apache能否正常启动,调试到能够正常启动http://192.168.0.88
(3)下载jk2.0.4后解压缩文件
(4)将解压缩后的目录中的modules目录中的mod_jk2.so文件复制到apache的安装目录下的modules目录中,我的为C:\Program Files\Apache Group\Apache2\modules
(5)修改apache的安装目录中的conf目录的配置文件httpd.conf,在文件中加LoadModule模块配置信息的最后加上一句LoadModule jk2_module modules/mod_jk2.so
(6)分别修改三个tomcat的配置文件conf/server.xml,修改内容如下
修改前
<!-- An Engine represents the entry point (within Catalina) that processes
every request. The Engine implementation for Tomcat stand alone
analyzes the HTTP headers included with the request, and passes them
on to the appropriate Host (virtual host). -->
<!-- You should set jvmRoute to support load-balancing via AJP ie :
<Engine name="Standalone" defaultHost="localhost" jvmRoute="jvm1">
-->
<!-- Define the top level container in our container hierarchy -->
<Engine name="Catalina" defaultHost="localhost">
修改后
<!-- An Engine represents the entry point (within Catalina) that processes
every request. The Engine implementation for Tomcat stand alone

on to the appropriate Host (virtual host). -->
<!-- You should set jvmRoute to support load-balancing via AJP ie :-->
<Engine name="Standalone" defaultHost="localhost" jvmRoute="tomcat1">
<!-- Define the top level container in our container hierarchy
<Engine name="Catalina" defaultHost="localhost">
-->
将其中的jvmRoute="jvm1"分别修改为jvmRoute="tomcat1"和jvmRoute="tomcat2"和jvmRoute="tomcat3"

[channel.socket:192.168.0.1:8009]

#配置第一个服务器
tomcatId=tomcat1 #要和tomcat的配置文件server.xml中的jvmRoute="tomcat1"名称一致
debug=0
lb_factor=1 #负载平衡因子,数字越大请求被分配的几率越高
