Tomcat與resin集羣解決session的問題

Tomcatresin集羣解決session的問題

這裏測試的是tomcat 6.0與resin 4.0的.

Tomcatresin集羣解決session的不同方法

Tomcat集羣把session寫入到memcached配置,<Context></Context>字段添加如下(需要驅動包,google有下)

  <Context path="" docBase="/usr/local/tomcat/llq/ROOT/ "  reloadable="true">

  <Manager className="de.javakaffee.web.msm.MemcachedBackupSessionManager" 

     memcachedNodes="n1:192.168.2.245:3000" 

     requestUriIgnorePattern=".*\.(png|gif|jpg|css|js)$" 

     sessionBackupAsync="false" 

     sessionBackupTimeout="100"

transcoderFactoryClass="de.javakaffee.web.msm.serializer.javolution.JavolutionTranscoderFactory"    copyCollectionsForSerialization="false" 

     /> 

</Context>

 

 

Resin集羣通過nginxjvm-route解決配置

 <web-app-default>

      <session-config>

      <use-persistent-store/>

      <always-save-session/>

    </session-config>

   </web-app-default>

 

  </cluster>

 <cluster id="cshop">

    <server-default>

      <jvm-arg>-Xms256m</jvm-arg>

      <jvm-arg>-Xmx256m</jvm-arg>

      <jvm-arg>-Xss96m</jvm-arg>

   </server-default>

        <resin:import path="${resin.home}/conf/app-default.xml"/>

    <server id="cshop" address="127.0.0.1" port="6809">

        <http id="" port="9000"/>

    </server>

    <host id="" root-directory=".">

           <web-app id="/" root-directory="/usr/local/wwwweb " />

    </host>

  <character-encoding>UTF-8</character-encoding>

 </cluster>

 

 

resin集羣把session寫入到memcached配置通過網上找了個別人分享的模塊( memsession.rar),但測試沒成功,不知道那位博友有更好的方法,分享下.
