一、FastDFS简介
FastDFS是一个个人开发的、轻量级的、开源的分布式文件系统，纯C语言编写，其功能包括：文件存储、文件同步、文件访问（文件上传、文件下载）等，解决了大容量存储和负载均衡的问题，具有稳定、高效、易用的优点。

二、安装环境
1、操作系统：Ubuntu 32bit
2、部署结构：1个tracker、1个storage（1组），PC单机（即tracker、storage均在同一台电脑上）
三、安装过程
官方安装文档：http://code.google.com/p/fastdfs/wiki/Setup
1、获取安装包：从项目主页（http://code.google.com/p/fastdfs/downloads/list ）下载部署包 FastDFS_v1.29.tar.gz (FastDFS Server with PHP client extension source code V1.29, 2010-6-30最新发布版本）。
2、解压安装包，然后切换到解压后的 FastDFS 主目录执行安装，即依次执行：
Cmd代码
tar xzf FastDFS_v1.29.tar.gz
cd FastDFS
./make.sh
./make.sh install
注意：
1）如果无法执行，则需要先安装gcc，Ubuntu系统可通过：sudo apt-get install gcc 安装。
2）Ubuntu系统上安装时需要将 make.sh 最后一段if去掉（从 if [ "$uname" = "Linux" ]; then 开始到倒数第2行），否则 ./make.sh install 时会报错。
3）执行./make.sh install时可能需要 root 权限。
3a、配置tracker
1）在FastDFS主目录的 conf 目录下有配置文件样例 tracker.conf，打开该文件，找到下列片段，红色 部分根据实际情况进行修改：
# the base path to store data and log files
base_path=/home/yuqing/fastdfs
2）启动tracker服务：
命令格式：/usr/local/bin/fdfs_trackerd <tracker_conf_filename>
实例：/usr/local/bin/fdfs_trackerd /FastDFS/conf/tracker.conf
3b、配置storage
1）在FastDFS主目录的 conf 目录下有配置文件样例 storage.conf，打开该文件，找到下列片段，红色 部分根据实际情况进行修改：
# the base path to store data and log files
base_path=/home/yuqing/fastdfs
# store_path#, based 0, if store_path0 not exists, it's value is base_path
# the paths must be exist
store_path0=/home/yuqing/fastdfs
#store_path1=/home/yuqing/fastdfs2
# tracker_server can ocur more than once, and tracker_server format is
# "host:port", host can be hostname or ip address
tracker_server=192.168.209.121:22122
2）启动storage服务：
命令格式：/usr/local/bin/fdfs_storaged <storage_conf_filename>
实例：/usr/local/bin/fdfs_storaged /FastDFS/conf/storage.conf
第1次启动将会在所设置的存储路径下创建256个子文件夹，需要一些时间。
3）运行监控程序：
命令格式：/usr/local/bin/fdfs_monitor <storage_conf_filename>
实例：/usr/local/bin/fdfs_monitor /FastDFS/conf/storage.conf
控制台将会显示存储服务器的一些信息，类似如下：
Txt代码
base_path=/FastDFS/logs, connect_timeout=30, network_timeout=60, tracker_server_count=1, anti_steal_token=0, anti_steal_secret_key length=0
server_count=1, server_index=0
tracker server is 127.0.0.1:22122
group count: 1
Group 1:
group name = group1
free space = 42 GB
storage server count = 1
active server count = 1
storage_port = 23000
storage_http_port = 8888
store path count = 1
subdir count per path= 256
current write server index = 0
Host 1:
ip_addr = 127.0.0.1 (localhost) ACTIVE
http domain =
version = 1.29
up time = 2010-07-20 16:52:44
total storage = 49GB
free storage = 42GB
upload priority = 10
store_path_count = 1
subdir_count_per_path = 256

last_heart_beat_time = 2010-07-20 17:23:31
last_source_update = 2010-07-20 17:16:43
last_sync_update = 1970-01-01 08:00:00
last_synced_timestamp= 1970-01-01 08:00:00
4、测试安装是否成功，上传一个文件：
1）在 storage 服务器上 ，通过提供的命令行工具进行上传：
命令格式：/usr/local/bin/fdfs_test <storage_conf_filename> <operation>
实例：/usr/local/bin/fdfs_test /FastDFS/conf/storage.conf upload /home/x.zip
控制台将会一些信息，类似如下：

file size=2688829
file url: http://127.0.0.1/group1/M00/00/00/fwAAAUxFaXsAAAAAACkHPTYooKs470_big.zip
至此，基本的安装已经成功。
说明：
1）在 tracker 和 storage 服务器是相互独立的情况下，在完成安装步骤的1-2后，第3步根据是 tracker 或 storage 而分别执行对应的 3a 或 3b 步骤即可。
2）storage 服务器是以心跳的方式主动向 tracker 服务器汇报自己的信息的，所以启动 tracker 和 storage 的顺序是任意的。
