分布式存储服务器FastDFS - 入门介绍与部署搭建

1，简介

FastDFS是一款类GoogleFS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，GoogleFS以及FastDFS、mogileFS、HDFS、TFS等类GoogleFS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。

FastDFS是为互联网应用量身定做的分布式文件系统，充分考虑了冗余备份、负载均衡、线性扩容等机制，并注重高可用、高性能等指标。和现有的类Google FS分布式文件系统相比，FastDFS的架构和设计理念有其独到之处，主要体现在轻量级、分组方式和对等结构三个方面。

FastDFS是由国人余庆所开发，其项目地址：https://github.com/happyfish100

2，架构

2.1，架构图

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。

3，部署安装

3.1，安装包准备

执行下面的shell，下载安装包，分别是libfastcommon基础组件、fastdfs、nginx、fastdfs-nginx-module。

wget https://github.com/happyfish100/libfastcommon/archive/V1.0.7.tar.gz
wget https://github.com/happyfish100/fastdfs/archive/V5.05.tar.gz
wget http://nginx.org/download/nginx-1.14.0.tar.gz
wget http://jaist.dl.sourceforge.NET/project/fastdfs/FastDFS%20Nginx%20Module%20Source%20Code/fastdfs-nginx-module_v1.16.tar.gz

3.2，gcc gcc-c++等环境准备

yum -y install gcc gcc-c++ autoconf automake
yum -y install zlib zlib-devel openssl openssl-devel pcre-devel

3.3，安装libfastcommon基础组件

3.4，安装fastdfs

安装

配置文件

# the base path to store data and log files
base_path=/home/fastdfs/tracker/data-and-log

mkdir -p /home/fastdfs/tracker/data-and-log

# the base path to store data and log files
base_path=/home/fastdfs/storage

# store_path#, based 0, if store_path0 not exists, it's value is base_path
# the paths must be exist
store_path0=/home/fastdfs/storage/images-data0
store_path1=/home/fastdfs/storage/images-data1
store_path2=/home/fastdfs/storage/images-data2

# tracker_server can ocur more than once, and tracker_server format is
#  "host:port", host can be hostname or ip address
tracker_server=192.168.80.82:22122

mkdir -p  \
/home/fastdfs/storage/images-data0 \
/home/fastdfs/storage/images-data1 \
/home/fastdfs/storage/images-data2

启动测试

storage server

3.4，client测试

# the base path to store log files
base_path=/home/fastdfs/client/data-and-log

# tracker_server can ocur more than once, and tracker_server format is
#  "host:port", host can be hostname or ip address
tracker_server=192.168.80.82:22122

3.5，安装nginx及其插件

安装

# 解压nginx的fastdfs插件文件
tar -zxvf fastdfs-nginx-module_v1.16.tar.gz

# 修改配置文件中的无效路径，把local去掉
vim fastdfs-nginx-module/src/config

CORE_INCS="$CORE_INCS /usr/local/include/fastdfs /usr/local/include/fastcommon/"
修改为
CORE_INCS="$CORE_INCS /usr/include/fastdfs /usr/include/fastcommon/"

复制文件：cp fastdfs-5.05/conf/http.conf /etc/fdfs
复制文件：cp fastdfs-5.05/conf/mime.types /etc/fdfs


sudo apt-get install openssl libssl-dev
sudo apt-get install libpcre3 libpcre3-dev
