terracotta3.7.7+apche2.2+tomcat6集群配置

         
terracotta是一家美国公司做的集群框架。是分布式缓存线性扩展平台。它巧妙得隐藏了多个分布式JVM带来的复杂性，使得java对象能够透明得在多个JVM集群中进行分享和同步，并能够进行持久化。
terracotta是怎么样的框架这里不多做叙述。大家可以百度了解。
下面开始集群的配置。
需要用到的软件如，terracotta3.7.7，apche2.2X(32),tomcat6(32).环境windows7
先配置apche跟tomcat集群。
首先下载好apche2.2X(32)。按流程装好apche
然后下载tomcat6(免安装).
下载负载均衡插件tomcat-connectors-1.2.40-windows-i386-httpd-2.0.x 注意tomcat 版本和apache版本
下载好后解压tomcat-connectors-1.2.40-windows-i386-httpd-2.0.x 将里面的mod_jk.so 放到apached的modules下面。
之后新建mod_jk.conf
内容如下：
LoadModule jk_module "D:/Program Files (x86)/Apache Group/Apache2.2/modules/mod_jk.so"  
JkWorkersFile "conf/workers.properties"  
JkMount /*.jsp controller  
JkMount /*.do controller
然后将mod_jk.conf文件复制到apche conf文件夹下面
之后新建workers.properties文件
内容如下
    #server  
    worker.list = controller  
    #========tomcat1========  
    worker.tomcat1.port=7010  
    worker.tomcat1.host=localhost  
    worker.tomcat1.type=ajp13  
    worker.tomcat1.lbfactor = 1  
    #========tomcat2========  
    worker.tomcat2.port=7011  
    worker.tomcat2.host=localhost  
    worker.tomcat2.type=ajp13  
    worker.tomcat2.lbfactor = 1  
    #========controller,负载均衡控制器========  
    worker.controller.type=lb  
    worker.controller.balanced_workers=tomcat1,tomcat2  
    worker.controller.sticky_session=true
    #worker.controller.sticky_session_force=1  
    #worker.controller.sticky_session=1
然后也将此文件复制到apche conf文件夹下面。
在apche conf文件夹下面找到httpd.conf
在最下面加上这句include "D:\Program Files (x86)\Apache Group\Apache2.2\conf\mod_jk.conf"
apche 配置基本完成
tomcat主要是配置conf下面的service文件修改端口等。如ajp访问协议主要是联通apche跟tomcat的。
修改service文件如下
tomcat1

自此集群已经配置好。
现在开始配置terracotta
首先配置tc-config文件
内容如下
    <?xml version="1.0" encoding="UTF-8" ?>  
    <tc:tc-config xmlns: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>  
        <property name="l2.nha.dirtydb.autoDelete" value="true"/>  
        <property name="l1.cachemanager.enabled" value="true"/>  
        <property name="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">

          <dso-port bind="127.0.0.1">9510</dso-port>  
          <jmx-port bind="127.0.0.1">9520</jmx-port>  
          <l2-group-port bind="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-group group-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>
然后在terracotta解压下的bin文件下面把tc-config.xml复制过来。
然后将terracotta session文件夹下面 terracotta-session-1.3.7跟common下面的
terracotta-toolkit-1.6-runtime-5.7.0复制到tomcat, lib下面。
然后cmd 命令窗口cd到terracotta3.7.7-bin下执行tim-get.bat tc-config.xml
之后执行start-tc-server.bat
会看到如下
 
然后在需要应用的tomcat的应用下面的META-INF 新建context.xml 并将一下内容复制进去
<?xml version="1.0" encoding="UTF-8"?>
<Context>
    <Valve className="org.terracotta.session.TerracottaTomcat60xSessionValve" tcConfigUrl="127.0.0.1:9510" />
</Context>


之后分别启动两个tomcat,apche

测试页面见附件
有一点要提醒的是请注意jdk跟tomcat版本对应。
本文过程经过实践。也参考了csdn的其他博友的文章。
参考过如博友飞*天的文章。
