一般来说，实现Apache与Tomcat6的负载均衡有两种方式，一种是使用mod_jk，另一种是使用mod_proxy模块。本文只讨论mod_jk方式。
无论使用哪种方式，一般都要经过以下这几个步骤（同一台机器）：
下面来详细说下详细的配置步骤
注：这一步跟负载均衡没关系，没有负载均衡也要进行这一步
首先下载Tomcat6.*.*.zip，解压后进行重命名，复制三个，分别是Tomcat6A，Tomcat6B，Tomcat6C
startup.bat只是在.zip格式的Tomcat压缩包里才有，使用安装包安装的好像没有。找到这个文件，打开后修改
对与Tomcat6A：
set CATALINA_HOME=%CURRENT_DIR%为set CATALINA_HOME=C:/Program Files/Apache Software Foundation/Tomcat6A、
对于Tomcat6B：
注：这步也是和负载均衡直接相关，但不是负载均衡中的关键，只是个副产品（byproduct）
为了防止人们直接访问某个Tomcat（因为这样会使负载均衡器失去意义），所以我们要关掉它的HTTP连接器，使得这些Tomcat只能通过AJP协议接收Apache转发过来的请求，因此需要停止HTTP/1.1连接器
注：这是实现负载均衡的关键一步，这一步做了两件事，一是配置了Standalone Engine，二是赋予这个Engine一个id：jvmRoute
每个Tomcat worker的server.xml中都有有关Engine的配置（语句）。这个Engine是一个和Catalina Engine一样级别最高的Engine，代表整个Catalina Servlet Engine。这条配置语句在server.xml中，jvmRoute的值必须是唯一的，在本例中，各个Tomcat实例的配置如下
Tomcat6A：
<!--You should set jvmRoute to support load-balancing via AJP-->
<Engine name="Standalone" defaultHost="localhost" jvmRoute="Tomcat6A">
Tomcat6B:
<!--You should set jvmRoute to support load-balancing via AJP-->
<Engine name="Standalone" defaultHost="localhost" jvmRoute="Tomcat6A">
Tomcat6C:
<!--You should set jvmRoute to support load-balancing via AJP-->
<Engine name="Standalone" defaultHost="localhost" jvmRoute="Tomcat6A">
注：这一步其实可以和上一步合并
因为我们配置了Standalone Engine，因此需要注释掉Catalina Engine。具体做法是：在server.xml中找到相应代码进行注释，结果如下：、
<!--
<Engine name=-"Catalina" defaultHost="localhost">
-->
注：粗体字为与负载均衡有直接关系的配置语句
在Apache Http Server下的conf文件夹中打开httpd.conf，添加下面的语句到其末尾
LoadModule jk_module modules/mod_jk.so
JkWorkersFile conf/workers.properties
JkLogLevel error
JkLogFile "C:/Program Files/Apache Software Foundation/Apache2.2/logs/mod_jk.Log"
在workers.proterties中每一个Tomcat实例一般有这几个属性需要配置，分别是：
type（类型）： 一般有ajp13（代表Tomcat的worker），lb负载
host（主机）： Tomcat所在机器的ip地址
port（端口）： worker所监听的端口号
lbfactor（负载权重）： 影响负载均衡器在分发请求时所分配的请求数，相对大小更重要
在本例中，具体配置如下：
Tomcat6A：
worker.Tomcat6A.type = ajp13
worker.Tomcat6A.host = 192.168.9.182
worker.Tomcat6A.port = 8009
worker.Tomcat6A.lbfactor=10
Tomcat6B:
worker.Tomcat6B.type = ajp13
worker.Tomcat6B.host = 192.168.9.182
worker.Tomcat6B.port = 8010
worker.Tomcat6B.lbfactor = 10
Tomcat6C:
worker.Tomcat6C.type = ajp13
worker.Tomcat6C.host = 192.168.9.182
worker.Tomcat6C.port = 8011
worker.Tomcat6C.lbfactor = 10
（这里的host值就是自己机器的ip地址，需要查看自己的机器的ip地址来替代这个地址）
在worker.properties文件中添加这两条配置语句
worker.bal1.type = lb
worker.bal1.sticky_session = 1
worker.bal1.balance = Tomcat6A, Tomcat6B, Tomcat6C
sticky_session属性设为1，这样负载均衡器lb就会尽量保持一个session，也就是使用户在一次会话中跟同一个Tomcat进行交互。（我猜如果不能保持跟同一个Tomcat进行交互，也就不能保持一个session）。
balance属性可以告诉mod_jk模块那些worker由lb负载均衡器控制
利用这个Worker，我们可以获得负载的实时统计信息
在worker.properties中添加
worker.staat1.type = status
到现在为止，我们已经配置好了三个ajp13 worker，一个lb worker，一个status worker。接下来需要做的就是告诉mod_jk这些worker的信息，在worker.properties中添加这条配置语句就可以做到：
worker.list = bal1, stat1
worker.list = bal1, stat1
worker.Tomcat6A.type = ajp13
worker.Tomcat6A.host = 192.168.9.182
worker.Tomcat6A.port = 8009
worker.Tomcat6A.lbfactor = 10
worker.Tomcat6B.type = ajp13
worker.Tomcat6B.host = 192.168.9.182
worker.Tomcat6B.port = 8010
worker.Tomcat6B.lbfactor = 10
worker.Tomcat6C.type = ajp13
worker.Tomcat6C.host = 192.168.9.182
worker.Tomcat6C.port = 8011
worker.Tomcat6C.lbfactor = 10
worker.bal1.type = lb
worker.bal1.stick_session = 1
worker.bal1.balance_workers = Tomcat6A, Tomcat6B, Tomcat6C
worker.stat1.type = status
在Tomcat的目录下找到webapps/examples/jsp/目录下创建一个index.jsp文件，内容如下：
其他两个Tomcat所做的操作类似，只是index.jsp中的内容变了一下，分别是：
配好后，重启Tomcat和Apache Http Server，顺序为 关闭Apache->关闭Tomcat->启动Tomcat->启动Apache
在浏览器中输入http://localhost/examples/jsp/index.jsp，然后运行多个浏览器实例（同一个浏览器的标签式浏览不行，因为很多标签式浏览被设置为共享session），如果出现不同的页面，就说明负载均衡配置成功了。
在浏览器中输入http://localhost/jkstatus/，，将出现目前负载情况的统计资料，如下图所示：
