老马哥：
谢谢你的指导，有进展了，不过我还是有点看不懂，希望你来指点一下：
red5不用配module的，应该是terracotta的官方给了red5一个tc-config.xml文件吧，用这个来集群的，我刚刚找到了这个tc-config.xml文件，是这样写的：
<?xml version="1.0" encoding="UTF-8"?>
<con:tc-config xmlns:con="http://www.terracotta.org/config">

</con:tc-config>
与这个文件在一起的还有一个src文件夹，里面有些类供这个xml加载。
这个是官方提供的文档：http://www.terracotta.org/confluence/display/wiki/Red5+and+Terracotta+POC
而官方文档提供的是linux的操作系统，而且又是2-3年前的，版本又低，真看不懂里面terracotta是怎么集群的··

在terracotta官网上看到：terracotta能集群很多服务器，tomcat、weblogic、jboss等等，这些在tc-config.xml的client节点下的module下配置就可以了，可官网提供的module的name有限啊，在官网上看到terracotta能集群red5的，可red5的module怎么配啊？

经过大家的帮助，集群终于成功了，但是session貌似不能共享啊：
这个是我的tc-config.xml文件：
<?xml version="1.0" encoding="UTF-8"?>
<tc:tc-config xsi:schemaLocation="http://www.terracotta.org/schema/terracotta-4.xsd" xmlns:tc="http://www.terracotta.org/config" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">

</tc:tc-config>

启动terracotta的时候也很清楚的看到了集群成功的字样，这个是日志：
F:\terracotta>bin\start-tc-server.bat -n zhangbei
2010-03-19 17:07:18,562 INFO - Terracotta 3.2.1, as of 20100302-130324 (Revision

2010-03-19 17:07:37,421 INFO - NodeID[192.168.2.3:9510] joined the cluster

然后我就用tomcat里面的例子来测试（jsp-examples和jsp-examples3，其实都是一样的文件）。
打开http://192.168.2.13:8080/jsp-examples/cal/login.html，登陆后就开始修改日志，我在同一台机器上修改后，可以看到效果，但用另一台登陆后，就看不到修改后的效果了···
这个是怎么回事？
是我的tc-config.xml没配好？
有的时候登陆后，修改时，页面还有这个错误：You must enter your name and email address correctly.

这个是怎么回事？

还有就是TC的控制台，虽然觉得非常美观，但我不怎么会看，有这方面的资料提供吗？

老马哥：
我按你的tc-config.xml文件配下去结果没有集群起来，但也没有报错，2个terracotta服务器开启之后，在terracotta控制台上看着，server1和server2在那里乱晃，要么server1变成红色，要么server2变成红色，苦闷啊。
而我按这个这个tc-config.xml：
<servers>



<server host="192.168.2.13" name="zhangbei">
</server>

<server host="192.168.2.19" name="ceshi">
</server>

<ha>
<mode>networked-active-passive</mode>
<mode>
</mode>
</ha>

<update-check>
<enabled>true</enabled>
</update-check>

</servers>
文件配了之后，能显示集群成功，在打开测试页面的时候报TCNonPortableObjectError，是关于boot jar的错误，我按要求修改了tc-config.xml文件后，重启tomcat时却发现tomcat启动报错，连锁异常··

我也遇到这个问题了：
我用的版本是3.2.1，我的tc-config.xml文件是：
<servers>



<server host="192.168.2.13" name="zhangbei">
</server>

<server host="192.168.2.19" name="ceshi">
</server>

<ha>
<mode>networked-active-passive</mode>
</ha>

<update-check>
<enabled>true</enabled>
</update-check>

</servers>



<clients>
<modules>
<module name="tim-tomcat-5.5" version="2.1.1"/>

</modules>
</clients>

</instrumented-classes>

<web-applications>
<web-application>jsp-examples</web-application>
<web-application>jsp-examples1</web-application>
</web-applications>
</dso>
</application>
出现错误后，它提示要在tc-config.xml中的<dso>节点中加入，
<additional-boot-jar-classes>
<include>java.util.TimeZone</include>
</additional-boot-jar-classes>
这段，然后在生成boot.jar：
F:\terracotta>bin\make-boot-jar.bat -f F:\terracotta\tc-config.xml
然后再重启tomcat就可以了，
我按它的提示做了，可连tomcat启动都报错··好像是连锁异常吧
我还想知道的，刚刚老马说的修改web.xml或者conte.xml文件修改的是terracotta\sessions\conf-samples的文件还是tomcat中的呢？

我做的是terracotta集群tomcat，这个不是session集群吗？
他们有区别？

这个是我的tc-config.xml文件
<?xml version="1.0" encoding="UTF-8"?>

跟这个错误一样：http://forums.terracotta.org/forums/posts/list/2112.page

我bin\start-tc-server.bat -n zhangbei后得到的错误信息就是：
*************************************************************************
At least one server defined in the Terracotta configuration file is in
'temporary-swap-only' persistence mode. (Servers in this mode:
[zhangbei, ceshi].)

If even one server has persistence mode set to temporary-swap-only,
then High Availability mode must be set to 'networked-active-passive'

For servers in a mirror group, High Availability mode can be set per

High Availability for that mirror group.

See the Terracotta documentation for more details.
*************************************************************************
不加 -n 错误信息就是：
*******************************************************************************

*******************************************************************************
你说的那个 -f后面接的是什么意思我不是很明白，我加了之后就报找不到文件的错误。

还是有错：

tta\tc-config.xml'.
2010-03-16 12:06:25,781 INFO - Log file: 'C:\Documents and Settings\Administr

*************************************************************************

遇到问题了，我在tc-config.xml里面配了2个server，结果再启动服务时报错了：

F:\terracotta>bin\start-tc-server.bat
2010-03-16 10:52:07,250 INFO - Terracotta 3.2.1, as of 20100302-130324 (Revision

Server startup failed.

顺便还想了解的是，配置webAppliction的时候，一台pc上有2个tomcat的话，直接写工程名，没关系吗？

你们的客户端中为什么填这么多啊，什么意思呢？
<modules>
<module name="tim-tomcat-6.0" version="2.1.0"/>
<module name="tim-session-common" version="2.1.0"/>
<module name="tim-tomcat-common" version="2.1.0"/>
<module name="tim-tomcat-5.5" version="2.1.0"/>
</modules>
而我的modules里面只有一个：<module name="tim-tomcat-5.5" version="2.1.0"/>

dongen：
非常谢谢你耐心的指导。

那tc-cofing.xml中，只要在server标签下多加一个server就可以了？
client不需要改变？是这样的吗：
<servers>



<server host="server1">
<dso-port>9510</dso-port>
</server>
<server host="server2">
<dso-port>9510</dso-port>
</server>

<update-check>
<enabled>true</enabled>
</update-check>

</servers>



<clients>
<modules>
<module name="tim-tomcat-5.5" version="2.1.1"/>
</modules>
</clients>

在集群的时候会开启很多个tomcat，那tomcat的端口是不是都要修改，避免冲突啊？

我是照着老马的文章做的，我想是我太菜了，人家都写的那么详细了我还看不懂。
这个是老马写的安装过程：
安装过程
1、在所有机器上安装Java

2、在所有机器上安装Terracotta

3、选一台机器作为Terracotta服务器

4、在所有运行Tomcat的机器上也安装Terracotta，他们将称为Terracotta客户端

5、在应用服务器节点上安装Tomcat

6、把要部署的Web应用部署在所有Tomcat上

假如我现在有2台pc(ip1和ip2)，4个tomcattomcat（t1，t2，t3，t4）。
我是不是该在2台pc上都安装terracotta；
然后就混乱了，选一台机器做terracotta的服务器是怎么回事？
这样的话，2个terracotta的tc-config.xml会有什么不同？
如果我想在每台pc上安装2个tomcat，我是不是只要把tomcat解压到terracotta的session文件夹下？项目是不是部署在tomcat的webapps里面？

谢谢dongen
我明白许多了，

等会去搞搞多个terracotta和tomcat集群··
谢谢了！

谢谢了，问题就出在这里，我的jdk放在有空格的目录下了，而且我自己的startupTC.bat中，也有一点错误，看了你的之后就明白了··
非常感谢坛子里的哥哥们，虽然terracotta的资料很少，但大家都这么热心，相信任何困难都会克服的！

顺便追问一下：tc-config.xml中的<web-application>examples</web-application>中的examples是我们部署的工程名吧，那是不是意味着我们的项目要部署在terracotta上？
觉得很不可思议，我们自己开发的项目该部署到哪里呢？

看着马哥的http://blog.csdn.net/lima01/archive/2009/07/25/4379572.aspx文章，再启动startupTC.bat时报错了,当set JAVA_OPTS=%JAVA_OPTS%（这里没有空格时）%TC_JAVA_OPTS%错误信息为：
