1.軟體清單：

 （1）Apache HTTP server2.4_X64

 （2）Tomcat7_X64 

 （3）mod_jk_2.0.46.so

安裝apache，安裝完成後如下圖所示：

將mod_jk.so拷到modules目錄下面

修改apache配置檔案 http.conf

在apache安裝目錄下conf目錄中找到http.conf，更改 ServerName127.0.0.1:80

並且在檔案最後加上下面一句話就可以了

include conf/mod_jk.conf

http.conf 同目錄下，建立 mod_jk.conf 檔案，內容如下：

#載入 mod_jk.so 模組

LoadModule jk_module modules/mod_jk.so

#載入mod_jk.so 配置檔案

JkWorkersFile conf/workers.properties

#指定那些請求交給tomcat處理,"controller"為在workers.propertise裡指定的負載分配控制器 （ 比如制定 jsp 檔案：JkMount /*.jspcontroller ）

JkMount /* controller(分流所有請求)
 

http.conf 同目錄下，建立workers.properties檔案 ,內容如下:

#===server 列表
worker.list = controller,tomcat1,tomcat2
#========tomcat1 需要注意此名字對應tomcat中server.xml <Engine name="Catalina" defaultHost="localhost" jvmRoute="tomcat1"> ========
#==ajp13埠號，在tomcat下server.xml配置,預設8009
worker.tomcat1.port=8009(apj埠號)
worker.tomcat1.host=localhost
worker.tomcat1.type=ajp13
#server的加權比重，值越高，分得的請求越多
worker.tomcat1.lbfactor=1
# 給worker1定義了一個發生錯誤處理失敗後要引用的節點
worker.tomcat1.redirect= tomcat2
# worker “worker2″ 用掉10個套接字, 這些會保持不超過10鐘的快取
worker.tomcat1.cachesize=10
worker.tomcat1.cache_timeout=600
# worker “tomcat1″ 會請求作業系統給連線（connection）發出 KEEP-ALIVE 訊號
worker.tomcat1.socket_keepalive=1
# worker “tomcat1″ 試圖使ajp13 連線於5分鐘後斷開(週期性的)
worker.tomcat1.recycle_timeout=300

#========tomcat2========
worker.tomcat2.port=8209（apj埠號）
worker.tomcat2.host=localhost
worker.tomcat2.type=ajp13
worker.tomcat2.lbfactor=1
# 除非發生了錯誤並且處理失敗了，否則就禁用所有發給worker2的請求
worker.tomcat2.disabled=True
# worker “tomcat2″ 用掉10個套接字, 這些會保持不超過10鐘的快取
worker.tomcat2.cachesize=10
worker.tomcat2.cache_timeout=600
# worker “tomcat2″ 會請求作業系統給連線（connection）發出 KEEP-ALIVE 訊號
worker.tomcat2.socket_keepalive=1
# worker “tomcat2″ 試圖使ajp13 連線於5分鐘後斷開(週期性的)
worker.tomcat2.recycle_timeout=300

#========controller========
worker.controller.type=lb
#指定分擔請求的tomcat
worker.controller.balance_workers=tomcat1,tomcat2
worker.controller.sticky_session=1
 

<Server port="8005" shutdown="SHUTDOWN">
  <Connector port="8081" protocol="HTTP/1.1"
               connectionTimeout="20000"

    <Connector port="8009" protocol="AJP/1.3" redirectPort="8443" />

修改tomcat2/conf/server.xml檔案

<Server port="8205" shutdown="SHUTDOWN">
<Connector port="8082" protocol="HTTP/1.1"
               connectionTimeout="20000"

<Connector port="8209" protocol="AJP/1.3" redirectPort="8444" />
  <Engine name="Catalina" defaultHost="localhost" jvmRoute="tomact2">

修改tomcat1, tomcat2的server.xml,將叢集部分配置:
