Centos6.3 下安装 FastDHT + FastDFS

FastDHT－高效分布式Hash系统

FastDHT是一个基于键值对（Key Value Pair）的高效的分布式Hash系统，她可以用来存储大量的Key Value Pair，比如可以用来存储文件名映射表、session数据、用户相关数据等等。

FastDHT服务器端底层存储采用Berkeley DB，支持大数据量；网络IO采用libevent，支持大并发连接。FastDHT只用到了BDB最基本的存储功能，数据同步是自己实现的，采用了binlog的复制方式。

FastDFS是一款类Google FS的开源分布式文件系统，它用纯C语言实现，支持Linux、FreeBSD、AIX等UNIX系统。它只能通过专有API对文件进行存取访问，不支持POSIX接口方式，不能mount使用。准确地讲，Google FS以及FastDFS、mogileFS、HDFS、TFS等类Google FS都不是系统级的分布式文件系统，而是应用级的分布式文件存储服务。
