一、FastDFS简介
FastDFS是由happy_fish100开发的一个开源轻量级分布式文件系统,她对文件进行管理,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。特别适合以文件为载体的在线服务,如相册网站、视频网站等等。FastDFS服务端有两个角色:跟踪器(tracker)和存储节点(storage)。跟踪器主要做调度工作,在访问上起负载均衡的作用。系统结构图如下所示:

二、安装与配置
在上文《基于VMware环境Linux服务器集群方案--LVS+Keepalived (1)》拓扑图中已描述了FastDFS结构,包括两台服务器:
Tracker server: 192.168.195.3(Port: 22122)
Storage server: 192.168.195.4(Port: 23000)
1、安装FastDFS,下载FastDFS源码包,eg:FastDFS_v1.28.tar.gz,Tracker server与Storage server安装方式一样,过程如下:
#wget http://fastdfs.googlecode.com/files/FastDFS_v1.28.tar.gz
#tar -zvxf FastDFS_v1.28.tar.gz
#cd FastDFS
#./make.sh(如果需要HTTP支持,将make.sh中"# WITH_HTTPD=1"的#去掉)
#./make.sh install
#mkdir /etc/fdfs
#mkdir /home/yuqing/fastdfs
2、启动Tracker server
#cp conf/tracker.conf /etc/fdfs/
#/usr/local/bin/fdfs_trackerd /etc/fdfs/tracker.conf
3、启动Storage server
#cp conf/storage.conf /etc/fdfs/
#/usr/local/bin/fdfs_storaged /etc/fdfs/storage.conf
注:根据自身的真实环境修改tracker.conf和storage.conf,亦可参照《FastDFS配置文件详解》,本环境中需要将storage.conf的tracker_server值修改为192.168.195.3:22122。
三、FastDFS客户端PHP扩展库的安装与配置
目前FastDFS的PHP扩展不支持Windows平台,在安装PHP扩展前,应先安装FastDFS客户端(客户端安装过程同上)和PHP,扩展库安装如下所示:
#cd php_client(进入FastDFS安装包/FastDFS/php_client)
#/opt/php/bin/phpize
#./configure --with-php-config=/opt/php/bin/php-config
#make && make install
#cp ../conf/client.conf /etc/fdfs/(修改client.conf, eg:tracker_server=192.168.15.3:22122)
#cat fastdfs_client.ini >> /opt/php/etc/php.ini
修改php.ini的配置项目,如:
fastdfs_client.tracker_group_count = 1
fastdfs_client.tracker_group0 = /etc/fdfs/client.conf
重启web服务器即可。在php_client已经有扩展函数说明和程序示例。
