FastDFS介绍说明及安装方法

FastDFS是一个开源的轻量级分布式文件系统，它对文件进行管理，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。

一、安装libevent

fastDFS需要安装libevent比较新的版本，将本机的比较低的版本卸载了。

rpm -qa libevent

libevent-1.4.13-1.el6.x86_64

rpm -e --nodeps libevent

安装一个最新稳定版

wget https://github.com/downloads/libevent/libevent/libevent-2.0.18-stable.tar.gz

tar zxvf libevent-2.0.18-stable.tar.gz

cd libevent-2.0.18-stable

./configure

make && make install

为libevent创建软链接到/lib库下，64位系统对应/lib64

ln -s /usr/local/lib/libevent* /lib/

ln -s /usr/local/lib/libevent* /lib64/

二、安装FastDFS

wget http://fastdfs.googlecode.com/files/FastDFS_v3.06.tar.gz

tar zxvf FastDFS_v3.06.tar.gz

cd FastDFS

./make.sh

./make.sh install

三、配置FastDFS

环境：

tracker server

192.168.1.5

storage server

192.168.1.51

192.168.1.52

1、配置并启动 tracker server

①配置 tracker.conf

mkdir /data/fastdfs

vim /etc/fdfs/tracker.conf

base_path=/data/fastdfs

②启动 tracker

/usr/local/bin/fdfs_trackerd /etc/fdfs/tracker.conf

③开机启动

vim /etc/rc.local

/usr/local/bin/fdfs_trackerd /etc/fdfs/tracker.conf

2、配置并启动 storage server

①配置 tracker.conf

mkdir /data/fastdfs

mkdir /data/images

vim /etc/fdfs/storage.conf

base_path=/data/fastdfs

store_path0=/data/images

tracker_server=192.168.1.5:22122

②启动 tracker

/usr/local/bin/fdfs_storage /etc/fdfs/storage.conf

③开机启动

vim /etc/rc.local

/usr/local/bin/fdfs_storage /etc/fdfs/storage.conf

3、为storage节点安装fastdfs-nginx-module模块

①安装模块

安装Nginx详见：

需重新编译Nginx

wget http://fastdfs.googlecode.com/files/fastdfs-nginx-module_v1.10.tar.gz

tar zxvf fastdfs-nginx-module_v1.10.tar.gz

wget http://nginx.org/download/nginx-1.2.0.tar.gz

tar zxvf nginx-1.2.0.tar.gz

cd nginx-1.2.0

./configure --prefix=/usr/local/nginx --add-module=../fastdfs-nginx-module/src

make && make install

cd ..

②配置

编辑nginx.conf

vim /usr/local/nginx/conf/nginx.conf

server {

    listen       80;

    server_name  localhost;

    location /M00 {

        alias /data/images/data;

        ngx_fastdfs_module;

    }

    ......

}

给 storage 的存储目录做一个软连接

ln -s /data/images/data/ /data/images/data/M00

拷贝mod_fastdfs.conf 到 /etc/fdfs/

cp fastdfs-nginx-module/src/mod_fastdfs.conf /etc/fdfs/

vim /etc/fdfs/mod_fastdfs.conf

base_path=/data/fastdfs

tracker_server=192.168.1.5:22122

store_path0=/data/images

启动nginx

/usr/local/nginx/sbin/nginx

四、使用FastDFS

1、上传文件

FastDFS安装包中，自带了客户端程序，通过程序可以进行文件上传。在使用这个客户端程序之前，首先需要配置client.conf，然后再进行文件上传及下载。

在tracker上修改客户端配置文件client.conf

vim /etc/fdfs/client.conf

base_path=/data/fastdfs

tracker_server=192.168.1.5:22122

vim a.html

This Is FastDFS Test.

上传文件

/usr/local/bin/fdfs_test /etc/fdfs/client.conf upload a.html

This is FastDFS client test program v3.06
