[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。 |
2.3、运行
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] |
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 |
设置开机自动启动。
[root@tracker FastDFS]# vim /etc/rc.d/rc.local

至此storage安装完成。
3.2、配置
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
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。 |
3.3、运行
运行storage之前，先要把防火墙中对应的端口打开（本例中为23000）。
[root@storage1 FastDFS]# iptables -I INPUT -p tcp -m state --state NEW -m tcp --dport 23000 -j ACCEPT
[root@storage1 FastDFS]# /etc/init.d/iptables save
iptables：将防火墙规则保存到 /etc/sysconfig/iptables：[确定] |
启动storage，会根据配置文件的设置自动创建多级存储目录，确认启动是否成功。（查看是否对应端口23000是否开始监听）
[root@storage1 FastDFS]# /usr/local/bin/fdfs_storaged /etc/fdfs/storage.conf restart
data path: /fdfs/storage/data, mkdir sub dir...
mkdir data path: 00 ...
mkdir data path: 01 ...

data path: /fdfs/storage/data, mkdir sub dir done.
[root@storage1 FastDFS]# netstat -unltp | grep fdfs
tcp 0 0.0.0.0:23000 0.0.0.0:* LISTEN 1766/fdfs_storaged |
也可查看storage的日志是否启动成功或是否有错误。
[root@storage1 FastDFS]# cat /fdfs/storage/logs/storaged.log |
确认启动成功后，可以运行fdfs_monitor查看storage服务器是否已经登记到tracker服务器。
[root@storage1 FastDFS]# /usr/local/bin/fdfs_monitor /etc/fdfs/storage.conf

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 |
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。 |
4、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。
4.1、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。
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

运行./configure进行安装前的设置，主要设置安装路径、FastDFS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/fastdfs-nginx-module/src --with-pcre=/usr/local/src/pcre-8.34/ --with-zlib=/usr/local/src/zlib-1.2.8 |
运行make进行编译，确保编译成功。
[root@storage1 nginx-1.4.7]# make
运行make install进行安装。
[root@storage1 nginx-1.4.7]# make install |
将FastDFS的nginx插件模块的配置文件copy到FastDFS配置文件目录。
[root@storage1 nginx-1.4.7]# cp /usr/local/src/fastdfs-nginx-module/src/mod_fastdfs.conf /etc/fdfs/
|
安装完成后，nginx所有文件在/usr/local/nginx下：

drwxr-xr-x. 2 root root 4096 3月 26 03:11 sbin |
至此nginx以及FastDFS的nginx插件模块安装完成。
4.2、 配置
编辑/usr/local/nginx/conf配置文件目录下的nginx.conf，设置添加storage信息并保存。
[root@storage1 nginx-1.4.7]# vim /usr/local/nginx/conf/nginx.conf
将server段中的listen端口号改为8080：
listen 8080;
在server段中添加：
location ~/group[1-3]/M00 {
root /fdfs/storage/data;
ngx_fastdfs_module;
} |
编辑/etc/fdfs配置文件目录下的mod_fastdfs.conf，设置storage信息并保存。
[root@storage1 nginx-1.4.7]# vim /etc/fdfs/mod_fastdfs.conf
一般只需改动以下几个参数即可：
base_path=/fdfs/storage #保存日志目录
tracker_server=172.16.1.202:22122 #tracker服务器的IP地址以及端口号
storage_server_port=23000 #storage服务器的端口号
group_name=group1 #当前服务器的group名
url_have_group_name = true #文件url中是否有group名
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
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 |
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/ |
至此，nginx以及FastDFS插件模块设置完成。
4.3、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@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] |
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

Eerror.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。
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 |
5、 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
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

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
运行make进行编译，确保编译成功。
[root@storage1 nginx-1.4.7]# make
运行make install进行安装。
[root@storage1 nginx-1.4.7]# make install |
至此nginx以及nginx cache purge插件模块安装完成。
5.2、配置
编辑/usr/local/nginx/conf配置文件目录下的nginx.conf，设置负载均衡以及缓存。
[root@storage1 nginx-1.4.7]# vim /usr/local/nginx/conf/nginx.conf

} |
至此，nginx以及nginx cache purge插件模块设置完成。
5.3、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 |
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/:
总用量 8
drwx------. 3 nobody nobody 4096 3月 26 12:57 6

-rw-------. 1 nobody nobody 35686 3月 26 13:08 b1f6fb1f7266f796765b6d6965021116 |
如果要手动清除缓存，可以在文件URL之前加上purge：
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：
使用fdfs_upload_file上传（之前已经有演示）
使用C语言客户端接口上传
使用PHP客户端接口上传
使用Java客户端接口上传
使用Python客户端接口上传
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
使用fdfs_download_file通过tracker服务器下载
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
使用fdfs_monitor查看tracker和所有group的运行情况。
[root@tracker tmp]# /usr/local/bin/fdfs_monitor /etc/fdfs/client.conf
