一 简介
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。
二 安装
1, 本次安装采用三台centos5.10 linux操作系统
192.168.80.100 tracker Nginx(注意这台不安装fastsfd-niginx插件)
192.168.80.101 storage nginx
192.168.80.102 storage nginx
操作系统的安装这里不多说。
2, 准备编译环境 yum -y install gcc gcc+ gcc-c++ openssl openssl-devel pcre pcre-devel 三台机器都进行安装，并且创建两个新用户fastdfs 和nginx
useradd fastdfs -M -s /sbin/nologin useradd nginx -M -s /sbin/nologin
为了方便测试 请关闭防火墙 service iptables stop
3, 下载源码
敲 cd /usr/local/src/ 进入该目录下，运行如下命令，下载fastDFS 5.01
wget http://jaist.dl.sourceforge.net/project/fastdfs/FastDFS%20Server%20Source%20Code/FastDFS%20Server%20with%20PHP%20Extension%20Source%20Code%20V5.01/FastDFS_v5.01.tar.
下载 nginx 1.7.0
wget http://nginx.org/download/nginx-1.7.0.tar.gz
下载fastdfs-nginx-module_v1.16
wget http://jaist.dl.sourceforge.net/project/fastdfs/FastDFS%20Nginx%20Module%20Source%20Code/fastdfs-nginx-module_v1.16.tar.gz
4, 安装FastDFS （三台机器都要安装）
tar xf FastDFS_v5.01.tar.gz
cd FastDFS
./make.sh && ./make.sh install
5, 解压fastDFS-nginx-module
[root@localhost ~]# cd /usr/local/src/
[root@localhost src]# tar xf fastdfs-nginx-module_v1.16.tar.gz
6, 安装Nginx
192.168.80.100 tarcker 机器的安装
[root@localhost ~]# cd /usr/local/src/
[root@localhost src]# tar xf nginx-1.7.0.tar.gz
[root@localhost src]# cd nginx-1.7.0
[root@localhost nginx-1.7.0]# ./configure --user=nginx --group=nginx --prefix=/usr/local/nginx
[root@localhost nginx-1.7.0]# make
[root@localhost nginx-1.7.0]# make install
192.168.80.101,102 stroage nginx的安装
[root@localhost ~]# cd /usr/local/src/
[root@localhost src]# tar xf nginx-1.7.0.tar.gz
[root@localhost src]# cd nginx-1.7.0
[root@localhost nginx-1.7.0]# ./configure --user=nginx --group=nginx --prefix=/usr/local/nginx
--add-module=../fastdfs-nginx-module/src //storage 安装nginx时需要加载该模块
[root@localhost nginx-1.7.0]# make
[root@localhost nginx-1.7.0]# make install
三 配置
192.168.80.100 tracker的配置
1,创建tracker数据以及日志存放目录
[root@localhost ~]# mkdir -p /data/fastdfs/tracker
2,修改FastDFS的tracker.conf配置 文件
[root@localhost ~]# vim /etc/fdfs/tracker.conf
base_path=/data/fastdfs/tracker
max_c/span>
work_threads=8
store_lookup=0
store_path=0
reserved_storage_space=4G //
run_by_group=fastdfs
run_by_user=fastdfs
rotate_error_log=true
配置的解析请参照我的以一篇文章 tracker配置文件解析
3,修改Nginx的配置文件
[root@localhost ~]# vim /usr/local/nginx/conf/nginx.conf
user nginx nginx; //此处为已经建立好的用户 和分组
worker_processes 3;
pid /usr/local/nginx/logs/nginx.pid;
worker_rlimit_nofile 1024;
events {
use epoll; // epoll是Linux内核为处理大批量文件描述符而作了改进的poll
worker_connections 1024;
}
http {
include mime.types;
default_type application/octet-stream;
log_format main '$remote_addr - $remote_user [$time_local] "$request" '
'$status $body_bytes_sent "$http_referer" '
'"$http_user_agent" "$http_x_forwarded_for"';
access_log /usr/local/nginx/logs/access.log main;
upstream server_g1{
server 192.168.80.101:80; //这里配置的是storage的IP 可以配多台
server 192.168.80.102:80;
}
server {
listen 80;
server_name localhost;
location /g1 {
proxy_redirect off;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_pass http://server_g1;
}
}
}
4,将tracker交给service管理并且设置开机启动
[root@localhost ~]# cp /usr/local/src/FastDFS/init.d/fdfs_trackerd /etc/init.d/
[root@localhost ~]# chkconfig --add fdfs_trackerd
[root@localhost ~]# chkconfig fdfs_trackerd on
配置storage （分别在192.168.80.101,102上进行配置）
1, 创建数据存放目录
[root@localhost ~]# mkdir -p /data/fastdfs/storage/data
2,修改FastDFS的storage.conf配置文件
[root@localhost ~]# vim /etc/fdfs/storage.conf
group_name=g1
base_path=/data/fastdfs
##工作线程数，通常设置为 CPU 数
work_threads=8
store_path_count=1
store_path0=/data/fastdfs/storage
##tracker_server 的地址
tracker_server=192.168.80.100:22122
##运行 FastDFS 的用户组
run_by_group=fastdfs
##运行 FastDFS 的用户
run_by_user=fastdfs
file_distribute_path_mode=1
rotate_error_log=true
3,把nginx模块的配置文件拷贝到 /etc/fdfs中，进行修改
[root@localhost ~]# cp /usr/local/src/fastdfs-nginx-module/src/mod_fastdfs.conf /etc/fdfs/
[root@localhost ~]# vim /etc/fdfs/mod_fastdfs.conf
c/span>
tracker_server=192.168.80.100:22122
group_name=g1
url_have_group_name = true
store_path_count=1
store_path0=/data/fastdfs/storage
4,修改nginx配置文件
[root@localhost ~]# vim /usr/local/nginx/conf/nginx.conf
user nginx nginx;
worker_processes 8;
pid /usr/local/nginx/logs/nginx.pid;
worker_rlimit_nofile 1024;
events {
use epoll;
worker_connections 1024;
}
http {
include mime.types;
default_type application/octet-stream;
log_format main '$remote_addr - $remote_user [$time_local] "$request" '
'$status $body_bytes_sent "$http_referer" '
'"$http_user_agent" "$http_x_forwarded_for"';
access_log /usr/local/nginx/logs/access.log main;
server {
listen 80;
server_name localhost;
location /g1/M00{
root /data/fastdfs/storage/data;
ngx_fastdfs_module;
}
}
}
5,把storage 交[root@localhost ~]# cp /usr/local/src/FastDFS/init.d/fdfs_storaged /etc/init.d/
[root@localhost ~]# chkconfig --add fdfs_storaged
[root@localhost ~]# chkconfig fdfs_storaged on
[root@localhost ~]# service fdfs_storaged start给service管理并设置开机启动
//创建软连接
[root@localhost ~]# ln -s /data/fastdfs/storage/data /data/fastdfs/storage/data/M00
四 测试
1,在192.168.80.100 上启动tracker，nginx
[root@localhost ~]# service fdfs_trackerd start
[root@localhost ~]# /usr/local/nginx/sbin/nginx
2,在192.168.80.101,102上面分别启动storage和nginx
[root@localhost ~]# service fdfs_storaged start
[root@localhost ~]# /usr/local/nginx/sbin/nginx
3配置一个client 在tracker上进行
[root@localhost ~]# vim /etc/fdfs/client.conf
base_path=/data/fastdfs
tracker_server=192.168.80.100:22122
4，查看集群详细
[root@localhost ~]# fdfs_monitor /etc/fdfs/client.conf
5，测上传
root@localhost ~]# fdfs_upload_file /etc/fdfs/client.conf aa.jpg
