terracotta+tomcat+apache集羣配置

Terracotta3.3.7+ tomcat6.0 + apache2.2.2集羣配置

一．目的

    Tomcat集羣配置，實現集羣服務器中session共享

二．準備材料：

    1. terracotta-3.7.7-2013-08-19_16-03-48-installer.jar

     2. httpd-2.2.25-win32-x86-openssl-0.9.8y.msi

     3. apache-tomcat-6.0.45-windows-x64.zip

     4. tomcat-connectors-1.2.40-windows-i386-httpd-2.2.x.zip

5.jdk環境必須爲1.6，terracotta3.7.7只能支持1.6（後來測試中改爲了1.7 發現也能使用）

 

三．配置兩個tomcat6.0

    新建兩個文件夾tom1,tom2, 將apache-tomcat-6.0.45-windows-x64.zip解壓後，分別放置到兩個文件夾下，如圖所示：  

       

因爲需要同時啓動兩個tomcat，所以必須要修改兩個端口，配置文件如下：

 

Tom1中的server.xml

Tom2 中的server.xml

 

<?xml version='1.0' encoding='utf-8'?>
<Server port="8007" shutdown="SHUTDOWN">
  <!--APR library loader.Documentation at /docs/apr.html -->
  <ListenerclassName="org.apache.catalina.core.AprLifecycleListener"SSLEngine="on" />
  <!--Initialize Jasperprior to webapps are loaded. Documentation at /docs/jasper-howto.html -->

  <!-- JMX Support forthe Tomcat server. Documentation at /docs/non-existent.html -->
  <ListenerclassName="org.apache.catalina.mbeans.ServerLifecycleListener" />
  <ListenerclassName="org.apache.catalina.mbeans.GlobalResourcesLifecycleListener"/>
 <GlobalNamingResources>
    <Resourcename="UserDatabase" auth="Container"
             type="org.apache.catalina.UserDatabase"
             description="User database that can be updated and saved"
              factory="org.apache.catalina.users.MemoryUserDatabaseFactory"
             pathname="conf/tomcat-users.xml" />
 </GlobalNamingResources> 
  <Servicename="Catalina">
    <Connectorport="8083" protocol="HTTP/1.1"
              connectionTimeout="20000"
              redirectPort="8446" />
    <Connectorport="8011" protocol="AJP/1.3"redirectPort="8446" />
    <Enginename="Catalina" defaultHost="localhost"jvmRoute="tomcat2">
          <ClusterclassName="org.apache.catalina.ha.tcp.SimpleTcpCluster"/>
   <RealmclassName="org.apache.catalina.realm.UserDatabaseRealm"
            resourceName="UserDatabase"/>
      <Hostname="localhost" appBase="webapps"
           unpackWARs="true" autoDeploy="true"
           xmlValidation="false" xmlNamespaceAware="false">
      </Host>
    </Engine>
  </Service>
</Server>

同時將兩個tomcat都加入windows服務中，

對於tom1，修改bin目錄下的tomcat6.exe爲tomcat6_1.exe，tomcat6w.exe爲tomcat6w_1.exe,用記事本打開service.bat,將裏面的tomcat6全部改爲tomcat6_1,同時修改set SERVICE_NAME=Tomcat6爲set SERVICE_NAME=Tomcat6_1，

同理對於tom2修改爲tomcat_2,

通過cmd界面，cd 進入tom1的bin目錄,執行service install命令安裝服務

同理，安裝好tom2.

 

 

四．配置apache

 雙擊httpd-2.2.25-win32-x86-openssl-0.9.8y.msi進行安裝，選擇文件夾爲D:\soft\apache (按自己喜歡的位置來),安裝成功後，開始進行配置。

解壓tomcat-connectors-1.2.40-windows-i386-httpd-2.2.x.zip，得到mod_jk.so，將其放入至apache安裝目錄的modules下面，然後打開conf文件夾下httpd.conf配置文件，向其中添加一條語句 Includeconf/mod_jk.conf

接着在conf裏面新建mod_jk.conf，填寫一些內容如下：

 

LoadModulejk_module "D:/soft/apache/modules/mod_jk.so"

JkWorkersFile"conf/workers.properties"

JkMount/*.jsp controller

JkMount/*.do controller

 

以上就配置好了apache的mod_jk模塊(負載均衡)，將*.jsp和*.do轉發給tomcat

 

接着在conf裏面新建一個workers.properties，內容如下：

#server 

worker.list =controller 

#========tomcat1======== 

worker.tomcat1.port=8010

worker.tomcat1.host=localhost 

worker.tomcat1.type=ajp13 

worker.tomcat1.lbfactor= 1 

#========tomcat2======== 

worker.tomcat2.port=8011

worker.tomcat2.host=localhost 

worker.tomcat2.type=ajp13 

worker.tomcat2.lbfactor= 1 

#========controller,負載均衡控制器======== 

worker.controller.type=lb 

worker.controller.balanced_workers=tomcat1,tomcat2 

worker.controller.sticky_session=false 

worker.controller.sticky_session_force=1 

#worker.controller.sticky_session=1

 

至此apache配置結束。

 

（其實到此就可以實現session共享了，只不過是tomcat自帶的粘性session，一當session過多後就會導致性能下降，可以寫個小web項目sharesession測試一下，修改web.xml文件，在<web-app></web-app>之間加入</description>，這是配置tomcat進行粘性session的標籤，最後新建index.jsp頁面，內容如下：）

<%@ pagelanguage="java" import="java.util.*"pageEncoding="UTF-8"%> 

<%@ pageimport="java.util.*" %> 

<html><head><title>ClusterApp Test</title></head> 

<body> 

Server Info: 

<% 

out.println(request.getLocalAddr()+ " : " + request.getLocalPort()+"<br>");%> 

<% 

  out.println("<br> ID " +session.getId()+"<br>"); 

  // 如果有新的 Session 屬性設置 

  String dataName =request.getParameter("dataName"); 

  if (dataName != null &&dataName.length() > 0) { 

     String dataValue =request.getParameter("dataValue"); 

     session.setAttribute(dataName, dataValue);

  } 

  out.println("<b>Session 列表</b><br>");

  System.out.println("********************"); 

  Enumeration e =session.getAttributeNames(); 

  while (e.hasMoreElements()) { 

     String name =(String)e.nextElement(); 

     String value =session.getAttribute(name).toString(); 

     out.println( name + " = " +value+"<br>"); 

         System.out.println( name + " =" + value); 

   } 

%> 

  <form action="index.jsp"method="POST"> 

    名稱:<input type=text size=20name="dataName"> 

     <br> 

    值:<input type=text size=20name="dataValue"> 

     <br> 

    <input type=submit> 

   </form> 

</body> 

</html>

 

打開瀏覽器後，輸入地址127.0.0.1:80/sharesession/index.jsp，即可訪問，多打開幾個頁面會發現，session並不會改變，改變的只是不同tomcat對請求進行處理。

 

四．配置terracotta

雙擊terracotta-3.7.7-2013-08-19_16-03-48-installer.jar安裝至D:\terracotta目錄下，在該目錄下添加tc-config.xml文件，內容如下：

 

<?xmlversion="1.0" encoding="UTF-8" ?> 
<tc:tc-configxmlns:tc="http://www.terracotta.org/config" 
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
 xsi:schemaLocation="http://www.terracotta.org/schema/terracotta-6.xsd"> 
  <tc-properties> 
    <propertyname="l2.nha.dirtydb.autoDelete" value="true"/> 
    <propertyname="l1.cachemanager.enabled" value="true"/> 
    <propertyname="logging.maxLogFileSize" value="1024"/> 
  </tc-properties> 
  <system> 
   <configuration-model>development</configuration-model> 
  </system> 
  <servers> 
    <server host="127.0.0.1"name="localhost" bind="0.0.0.0"> 
     <statistics>/opt/terracotta/server-statistics</statistics>  
      <dso-portbind="127.0.0.1">9510</dso-port> 
      <jmx-portbind="127.0.0.1">9520</jmx-port> 
      <l2-group-portbind="127.0.0.1">9530</l2-group-port> 
      <authentication/>
      <dso> 
       <client-reconnect-window>120</client-reconnect-window> 
        <persistence>     
         <mode>temporary-swap-only</mode> 
        </persistence> 
                     <garbage-collection> 
         <enabled>true</enabled> 
          <verbose>false</verbose> 
         <interval>3600</interval> 
        </garbage-collection> 
      </dso> 
    </server> 
    <mirror-groups>  
      <mirror-groupgroup-name="group1"> 
        <members> 
         <member>localhost</member> 
        </members>         
        <ha> 
         <mode>networked-active-passive</mode> 
          <networked-active-passive> 
           <election-time>5</election-time> 
         </networked-active-passive> 
        </ha> 
       </mirror-group> 
    </mirror-groups>      
    <ha> 
     <mode>networked-active-passive</mode> 
      <networked-active-passive> 
       <election-time>5</election-time> 
      </networked-active-passive> 
    </ha> 
    <update-check> 
      <enabled>true</enabled> 
     <period-days>10</period-days> 
    </update-check> 
  </servers> 
  <clients> 
    <logs>logs-%i</logs> 
  </clients> 
</tc:tc-config>

 

將D:\terracotta\sessions目錄下的terracotta-session-XXXXXXX.jar以及

D:\terracotta\common目錄下的terracotta-toolkit-1.6-runtime-XXXXX.jar

複製到tomcat的lib目錄下，然後在剛剛sharesession測試項目的META-INF文件夾下添加context.xml文件，內容如下:

<?xml version="1.0"encoding="UTF-8"?>

<Context>

    <Valve className="org.terracotta.session.TerracottaTomcat60xSessionValve"tcConfigUrl="127.0.0.1:9510" />

</Context>

配置到此結束了！

 

開始啓動terracotta，cmd中進入terracotta安裝目錄，然後執行 start-tc-server.bat批處理文件,如下圖：

 

啓動成功！

 

接着打開兩個tomcat6.0

 

 

均啓動成功！

 

最後打開apache，

 

 

啓動成功！

 

打開瀏覽器輸入

 

 

很明顯 session實現了共享， session值是一樣的，不一樣的只是請求處理的服務器。同時可以使用terracotta的Terracotta Developer Console進行查看

 

 

結果：測試中發現 Terracotta3.3.7 存儲的對象同樣也需要序列化，用了兩個tomcat，通過apache協調調度tomcat，有效的均衡了瀏覽器url請求，並且在後來的使用中將jdk改爲了1.7，並將tomcat6.0改爲了tomcat8.0，運行正常。
