一、 安装
(一) 下载FastDFS安装包
FastDFS官方论坛：http://www.csource.org
下载1：http://sourceforge.net/projects/fastdfs/files/
下载2：https://code.google.com/p/fastdfs/downloads/list
本手册使用CentOS 6.5 x86_64版操作系统，按照以下网络结构进行部署：
所需要下载的压缩包有：
FastDFS源代码：FastDFS_v5.01.tar.gz
nginx模块源代码：fastdfs-nginx-module_v1.15.tar.gz
nginx服务器源代码：nginx-1.4.7.tar.gz
nginx cache purge插件源代码：ngx_cache_purge-2.1.tar.gz
nginx依赖的pcre库源代码：pcre-8.34.tar.gz
nginx依赖的zlib库源代码：zlib-1.2.8.tar.gz
(二) 安装tracker
1. 安装
首先在172.16.1.202上安装FastDFS tracker，使用FastDFS_v5.01.tar.gz源代码包。
可以直接从Linux系统下载源代码包并解压安装。如果是在Windows系统下载，可以在Linux系统中挂载Windows的共享目录并且将源代码包复制进Linux系统内。挂载命令如下
[root@centos-db01 ~]# mount -o ro //Windows主机的IP地址/共享目录名 /挂载目标目录
l 首先将代码包复制到系统的/usr/local/src内（这一步可选），然后使用tar命令解压
[root@tracker opt]# cp FastDFS_v5.01.tar.gz /usr/local/src/
[root@tracker opt]# cd /usr/local/src/
[root@tracker src]# tar zxf FastDFS_v5.01.tar.gz
[root@tracker src]# cd FastDFS
[root@tracker FastDFS]# ll

l 至此tracker安装完成。
2. 配置
l 编辑配置文件目录下的tracker.conf，设置相关信息并保存。
[root@tracker FastDFS]# vim /etc/fdfs/tracker.conf
一般只需改动以下几个参数即可：
disabled=false #启用配置文件
port=22122 #设置tracker的端口号
base_path=/fdfs/tracker #设置tracker的数据文件和日志目录（需预先创建）
http.server_port=8080 #设置http端口号
如需要进行性能调优，可以参照附录的配置文件的详细说明。
3. 运行
l 运行tracker之前，先要把防火墙中对应的端口打开（本例中为22122）。
[root@tracker FastDFS]# iptables -I INPUT -p tcp -m state --state NEW -m tcp --dport 22122 -j ACCEPT
[root@tracker FastDFS]# /etc/init.d/iptables save
iptables：将防火墙规则保存到 /etc/sysconfig/iptables：[确定]
l 启动tracker，确认启动是否成功。（查看是否对应端口22122是否开始监听）
[root@tracker FastDFS]# /usr/local/bin/fdfs_trackerd /etc/fdfs/tracker.conf restart
[root@tracker FastDFS]# netstat -unltp | grep fdfs
tcp 0 0.0.0.0:22122 0.0.0.0:* LISTEN 1766/fdfs_trackerd
也可查看tracker的日志是否启动成功或是否有错误。
[root@tracker FastDFS]# cat /fdfs/tracker/logs/trackerd.log
l 设置开机自动启动。
[root@tracker FastDFS]# vim /etc/rc.d/rc.local

l 至此storage安装完成。
2. 配置
l 编辑配置文件目录下的storage.conf，设置相关信息并保存。
[root@storage1 FastDFS]# vim /etc/fdfs/storage.conf
一般只需改动以下几个参数即可：
disabled=false #启用配置文件
group_name=group1 #组名，根据实际情况修改
port=23000 #设置storage的端口号
base_path=/fdfs/storage #设置storage的日志目录（需预先创建）
store_path_count=1 #存储路径个数，需要和store_path个数匹配
store_path0=/fdfs/storage #存储路径
tracker_server=172.16.1.202:22122 #tracker服务器的IP地址和端口号

l 设置开机自动启动。
[root@storage1 FastDFS]# vim /etc/rc.d/rc.local
将运行命令行添加进文件：/usr/local/bin/fdfs_storaged /etc/fdfs/storage.conf restart
l 之后依次在172.16.1.204~208上全部安装上storage并确认运行正常。注意配置文件中group名参数需要根据实际情况调整，本例中group是这样分配的：
group1：172.16.1.203，172.16.1.204
group2：172.16.1.205，172.16.1.206
group3：172.16.1.207，172.16.1.208
另外每个group中所有storage的端口号必须一致。
(四) 在storage上安装nginx
在storage上安装的nginx主要为了提供http的访问服务，同时解决group中storage服务器的同步延迟问题。
1. 安装
首先在172.16.1.203上安装nginx，使用nginx-1.4.7.tar.gz源代码包以及FastDFS的nginx插件fastdfs-nginx-module_v1.15.tar.gz。
l 首先将代码包和插件复制到系统的/usr/local/src内（可选），然后使用tar命令解压
[root@storage1 opt]# cp nginx-1.4.7.tar.gz /usr/local/src
[root@storage1 opt]# cp fastdfs-nginx-module_v1.15.tar.gz /usr/local/src
[root@storage1 opt]# cp pcre-8.34.tar.gz /usr/local/src
[root@storage1 opt]# cp zlib-1.2.8.tar.gz /usr/local/src
[root@storage1 opt]# cd /usr/local/src/
[root@storage1 src]# tar zxf nginx-1.4.7.tar.gz
[root@storage1 src]# tar zxf fastdfs-nginx-module_v1.15.tar.gz
[root@storage1 src]# tar zxf pcre-8.34.tar.gz
[root@storage1 src]# tar zxf zlib-1.2.8.tar.gz
[root@storage1 src]# cd nginx-1.4.7

http.need_find_content_type=true #从文件扩展名查找文件类型（nginx时为true）
group_count = 3 #设置组的个数
在末尾增加3个组的具体信息：
[group1]
group_name=group1
storage_server_port=23000
store_path_count=1
store_path0=/fdfs/storage
[group2]
group_name=group2
storage_server_port=23000
store_path_count=1
store_path0=/fdfs/storage
[group3]
group_name=group3
storage_server_port=23000
store_path_count=1
store_path0=/fdfs/storage
l 建立M00至存储目录的符号连接。
[root@storage1 nginx-1.4.7]# ln -s /fdfs/storage/data /fdfs/storage/data/M00
[root@storage1 nginx-1.4.7]# ll /fdfs/storage/data/M00
lrwxrwxrwx. 1 root root 19 3月 26 03:44 /fdfs/storage/data/M00 -> /fdfs/storage/data/
l 至此，nginx以及FastDFS插件模块设置完成。
3. 运行
l 运行nginx之前，先要把防火墙中对应的端口打开（本例中为8080）。
[root@storage1 nginx-1.4.7]# iptables -I INPUT -p tcp -m state --state NEW -m tcp --dport 8080 -j ACCEPT
[root@storage1 nginx-1.4.7]# /etc/init.d/iptables save
iptables：将防火墙规则保存到 /etc/sysconfig/iptables：[确定]
l 启动nginx，确认启动是否成功。（查看是否对应端口8080是否开始监听）
[root@storage1 nginx-1.4.7]# /usr/local/nginx/sbin/nginx
ngx_http_fastdfs_set pid=40638
[root@storage1 nginx-1.4.7]# netstat -unltp | grep nginx
tcp 0 0.0.0.0:8080 0.0.0.0:* LISTEN 40639/nginx
也可查看nginx的日志是否启动成功或是否有错误。
[root@storage1 nginx-1.4.7]# cat /usr/local/nginx/logs/error.log
ngx_http_fastdfs_process_init pid=40640
[2014-03-26 03:47:17] INFO - local_host_ip_count: 2, 127.0.0.1 172.16.1.203

[2014-03-26 03:47:17] INFO - group 3. group_name=group3, storage_server_port=23000, path_count=1, store_path0=/fdfs/storage
在error.log中没有错误，既启动成功。可以打开浏览器，直接访问http://172.16.1.203:8080，查看是否弹出nginx欢迎页面。
之后依次在172.16.1.204~208上全部安装上nginx并确认运行正常。
l 设置开机自动启动。
[root@storage1 nginx-1.4.7]# vim /etc/rc.d/rc.local
将运行命令行添加进文件：/usr/local/nginx/sbin/nginx
(五) 在tracker上安装nginx
在tracker上安装的nginx主要为了提供http访问的反向代理、负载均衡以及缓存服务。
1. 安装
l 首先将代码包和插件复制到系统的/usr/local/src内（可选），然后使用tar命令解压
[root@tracker opt]# cp nginx-1.4.7.tar.gz /usr/local/src
[root@tracker opt]# cp ngx_cache_purge-2.1.tar.gz /usr/local/src
[root@tracker opt]# cp pcre-8.34.tar.gz /usr/local/src
[root@tracker opt]# cp zlib-1.2.8.tar.gz /usr/local/src
[root@tracker opt]# cd /usr/local/src/
[root@tracker src]# tar zxf nginx-1.4.7.tar.gz
[root@tracker src]# tar zxf ngx_cache_purge-2.1.tar.gz
[root@tracker src]# tar zxf pcre-8.34.tar.gz
[root@tracker src]# tar zxf zlib-1.2.8.tar.gz
[root@tracker src]# cd nginx-1.4.7
[root@tracker nginx-1.4.7]# ll

l 运行./configure进行安装前的设置，主要设置安装路径、nginx cache purge插件模块目录、pcre库目录、zlib库目录。
如果提示错误，可能缺少依赖的软件包，需先安装依赖包，再次运行./configure
[root@storage1 nginx-1.4.7]# ./configure --prefix=/usr/local/nginx --add-module=/usr/local/src/ngx_cache_purge-2.1 --with-pcre=/usr/local/src/pcre-8.34/ --with-zlib=/usr/local/src/zlib-1.2.8
l 运行make进行编译，确保编译成功。
[root@storage1 nginx-1.4.7]# make
l 运行make install进行安装。
[root@storage1 nginx-1.4.7]# make install
l 至此nginx以及nginx cache purge插件模块安装完成。
2. 配置

}
l 至此，nginx以及nginx cache purge插件模块设置完成。
3. 运行
运行nginx之前，先要把防火墙中对应的端口打开（本例中为8080）。
[root@tracker nginx-1.4.7]# iptables -I INPUT -p tcp -m state --state NEW -m tcp --dport 8080 -j ACCEPT
[root@tracker nginx-1.4.7]# /etc/init.d/iptables save
iptables：将防火墙规则保存到 /etc/sysconfig/iptables：[确定]
启动nginx，确认启动是否成功。（查看是否对应端口8080是否开始监听）
[root@tracker nginx-1.4.7]# /usr/local/nginx/sbin/nginx
ngx_http_fastdfs_set pid=40638
[root@tracker nginx-1.4.7]# netstat -unltp | grep nginx
tcp 0 0.0.0.0:8080 0.0.0.0:* LISTEN 40639/nginx
l 尝试上传一个文件到FastDFS，然后访问试试。先配置client.conf文件。
[root@tracker nginx-1.4.7]# vim /etc/fdfs/client.conf
修改以下参数：
base_path=/fdfs/tracker #日志存放路径
tracker_server=172.16.1.202:22122 #tracker服务器IP地址和端口号
http.tracker_server_port=8080 #tracker服务器的http端口号
使用/usr/local/bin/fdfs_upload_file上传一个文件，程序会自动返回文件的URL。
[root@tracker nginx-1.4.7]# /usr/local/bin/fdfs_upload_file /etc/fdfs/client.conf /mnt/monk.jpg
group3/M00/00/00/rBABz1MzKG6Ad_hBAACKLsUDM60560.jpg
然后使用浏览器访问：
可以看到文件被正确读取出来了。
查看nginx的access.log日志，可以看到访问返回200成功。
[root@tracker nginx-1.4.7]# tail -n 10 -f /usr/local/nginx/logs/access.log
172.16.1.201 - - [26/Mar/2014:13:15:00 +0800] "GET /group3/M00/00/00/rBABz1MzKG6Ad_hBAACKLsUDM60560.jpg HTTP/1.1" 200 35374 "-" "Mozilla/5.0 (Windows NT 6.1; WOW64; Trident/7.0; rv:11.0) like Gecko"
查看nginx的cache目录，可以看到已经生成了缓存文件。
[root@tracker nginx-1.4.7]# ll /var/cache/nginx/proxy_cache/ -R
/var/cache/nginx/proxy_cache/:

如果要手动清除缓存，可以在文件URL之前加上purge：
l 设置开机自动启动。
[root@tracker nginx-1.4.7]# vim /etc/rc.d/rc.local
将运行命令行添加进文件：/usr/local/nginx/sbin/nginx
至此，tracker服务器上的http反向代理+负载均衡+缓存已经安装完成。
二、 使用
1. 上传文件
FastDFS提供了多种方式上传文件：
l 使用fdfs_upload_file上传（之前已经有演示）
l 使用C语言客户端接口上传
l 使用PHP客户端接口上传
l 使用Java客户端接口上传
l 使用Python客户端接口上传
l 使用.NET客户端接口上传
根据具体情况选择使用。上传均支持断点续传。
2. 下载文件
l 使用fdfs_download_file通过tracker服务器下载
l 使用nginx通过http方式直接从storage下载（支持断点续传，作者推荐）
3. 监视服务器资源
l 使用fdfs_monitor查看tracker和所有group的运行情况。
