• tc-config.xml (ehcache3.4.0)版本已经被合并了里面包含terracotta

    This is the default Terracotta server configuration file for the Ehcache kit.  
  
    It defines a single offheap resource of 512MB to be used for caching data.  
  
    It also defines a single server, but you can add another one to benefit from high availability.

• 以上的配置文件为两个节点

• 分别在两个节点上运行相应命令。

# 1  
nohup ./bin/start-tc-server.sh  -f conf/tc-config.xml  -n s1 &  
# 2  
nohup ./bin/start-tc-server.sh  -f conf/tc-config.xml  -n s2 &  
  

• 这样两台基本的Ehcache 服务集群就搭建成功了。

• 文章写的比较着急，不忙了在继续整理，望理解。

• 测试代码
