Terrocotta 共享Session

1、./WEB-INF/lib中需要有两个jar
./META-INF
./META-INF/MANIFEST.MF
./META-INF/context.xml
./index.jsp
./WEB-INF
./WEB-INF/web.xml
./WEB-INF/lib
./WEB-INF/lib/terracotta-session-1.3.5.jar
./WEB-INF/lib/terracotta-toolkit-1.6-runtime-5.5.0.jar
./WEB-INF/classes
./WEB-INF/classes/com

 

2、web.xml配置 

<filter>
  <filter-name>terracotta-filter</filter-name>
        <filter-class>org.terracotta.session.TerracottaJetty61xSessionFilter</filter-class>
        <init-param>
                <param-name>tcConfigUrl</param-name>
                <param-value>192.168.1.191:9510</param-value>
        </init-param>
</filter>
<filter-mapping>
  <filter-name>terracotta-filter</filter-name>
          <url-pattern>/*</url-pattern>
          <dispatcher>ERROR</dispatcher>
          <dispatcher>INCLUDE</dispatcher>
          <dispatcher>FORWARD</dispatcher>
          <dispatcher>REQUEST</dispatcher>
  </filter-mapping>
</web-app>

 

3、./META-INF/context.xml 文件内容

 

<!-- The following is an example of a Tomcat Valve declaration to add to your application to enable
     terracotta express session clustering.
    
     In the example below you will likely need to adjust the className attribute to match
     your desired application server and the "tcConfigUrl" attribute should be changed to
     match the location of your Terracotta server(s).
    
     The order of <Valve> elements is relevant. The Terracotta Valve should always be listed first.
    
     This file should be placed at META-INF/context.xml for WAR deployment on tomcat, or at
     WEB-INF/context.xml for Jboss WAR deployment      
    
     Tomcat 5.0.x users must add a path attribute to the <Context path="/myApp"> element since it is not
     optional in that version
-->

<Context>
  <Valve className="org.terracotta.session.TerracottaTomcat60xSessionValve" tcConfigUrl="192.168.1.191:9510"/>
</Context>

 

<!-- tomcat 5.5.x -->
<!-- <Context> -->
<!--   <Valve className="org.terracotta.session.TerracottaTomcat55xSessionValve" tcConfigUrl="localhost:9510"/> -->
<!-- </Context> -->

<!-- tomcat 5.0.x -->
<!-- <Context path="/myApp"> -->
<!--   <Valve className="org.terracotta.session.TerracottaTomcat50xSessionValve" tcConfigUrl="localhost:9510"/> -->
<!-- </Context> -->

<!-- jboss 5.1.x -->
<!-- <Context> -->
<!--   <Valve className="org.terracotta.session.TerracottaJboss51xSessionValve" tcConfigUrl="localhost:9510"/> -->
<!-- </Context> -->

<!-- jboss 4.2.x -->
<!-- <Context> -->
<!--   <Valve className="org.terracotta.session.TerracottaJboss42xSessionValve" tcConfigUrl="localhost:9510"/> -->
<!-- </Context> -->

<!-- jboss 4.0.x -->
<!-- <Context> -->
<!--   <Valve className="org.terracotta.session.TerracottaJboss40xSessionValve" tcConfigUrl="localhost:9510"/> -->
<!-- </Context> -->

 

4、最重要的一点是：如果部署于两台机器 192.168.1.101 192.168.1.102 这两个机器作为后置机

前端必须有一个lvs ， 用户通过lvs进入访问 ，这时session才能共享。

我用是nginx
