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：

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：

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？

你说用另一台机器登录，是指登录另一台Tomcat还是用另一台机器做客户端？你用另一台机器作客户端，它产生的session根本地产生的session已经不一样了，所以不能共享session。

测试方法应该是从同一台机器上，相同的浏览器打开两个窗口，分别登录两台不同的tomcat，他们的session应该是可以共享的。

另外通过dev-console去看看Object Browser里面有几个session对象被创建了。需要展开session相关的数据结构去看。

有关dev-console的文档在这里：

1、将解压后的terracotta-3.2.1/session/conf-samples下的context.xml
文件分别覆盖到两台tomcat/conf/下替换掉默认的
vim context.xml
将localhost改为192.168.0.203(tcserver的ip)保存退出
2、将terracotta-3.2.1/session/terracotta-session-1.0.0.jar加入jar包到tomcat的lib目录下

tc启动正常

tomcat启动信息

到这里就停住了不动了...
首先我想问一下各位大哥，这里can;t connect to server 127.0.0.1:9510这里的127.0.0.1是在哪里修改，是tomcat端还是tc端？
上面有一行Configuration loaded from the server at '192.168.0.203:9510'.
也已经连接到tc了可为什么下面有有一行can't connect to server 127.0.0.1:9510？
再有我没有配置tc的配置文件，因为这种配置方法是朋友告诉我的，他说不用配置其他的，但是启动之后从到这里卡住了。
并且我在控制台看到也只有127.0.0.1本机的信息根本看不到客户端的连接！
谢谢各位！

contex.xml应该拷贝到web应用的META-INF目录下。
另外请删除 tomcat/config/Catalina下的所有文件。
还有就是你的tomcat启动脚本中是否还有dso相关的配置？如果有，也需要去掉。

老马

你好lima
你说的问题我该修改的已经该了
现在tomcat启动还是

到这里就卡住了
这是为什么呢？并且控制台也根本看不到客户端的信息！

在tomcat根目录上搜索一下：

Code:

find . -exec grep -H 127.0.0.1:9510 {} \;

看看能找到什么。

产生的临时文件都是127.0.0.1：9510,我的context.xml
<Valve className="org.terracotta.session.TerracottaTomcat60xSessionValve" tcConfigUrl="192.168.0.203:9510"/>
里面已经定义服务器端IP了

好像是服务器上tc-config.xml里面还在用127.0.0.1。把它改成真正的服务器地址。从新启动服务器试试。

老马

没有..我的服务器端的tc-config.xml里就是192.168.0.203

启动服务器的时候，用 -f <folder>/tc-config.xml指定一下tc-config.xml文件的目录。

你最后提交的log显示tc-config.xml保存在了：
/usr/tomcat1/temp/tc-config46725.xml
Code:

2010-03-24 11:00:08,717 INFO - Configuration loaded from the file at '/usr/tomcat1/temp/tc-config46725.xml'.

可是那里面显示的服务器ip是127.0.0.1.
Code:

./temp/tc-config46725.xml: <server host="127.0.0.1" name="127.0.0.1:9510" bind="0.0.0.0"> 
 ./temp/tc-config46725.xml: <member>127.0.0.1:9510</member>

老马

谢谢lima
问题解决了！

正常的应该是多台客户端都可以访问session的，但为啥我始终是session其他机子访问不到
