一、实验环境说明
操作系统： Centos 6.6 x64
FastDFS 相关版本： fastdfs-5.05 fastdfs-nginx-module-v1.16 libfastcommon-v1.0.7
web 服务器软件： nginx-1.7.8
角色分配： 2 个 tracker， 地址分别为:10.1.1.243 10.1.1.244 两块磁盘
2个 group：
G1:10.1.1.245 10.1.1.246 三块磁盘
G2:10.1.1.247 10.1.1.248 三块磁盘
Client：10.1.1.249
目录规划：
/dev/sdb1 /data1 日志元数据目录
/dev/sdc1 /data2 数据目录
关闭selinux和iptables
做时间同步，最好添加定时任务
配置好yum源，推荐国内源
分区格式化磁盘并创建挂载目录进行挂载
二、安装 libfastcommon 和 fastdfs(所有机器均安装)
1.下载所需软件（链接: https://pan.baidu.com/s/1eSvSRPg 密码: 7k66）
unzip libfastcommon-1.0.7.zip
cd libfastcommon-1.0.7
./make.sh
./make.sh install
cd ..
tar xf FastDFS_v5.05.tar.gz
cd FastDFS
sed -i 's#/usr/local/bin/#/usr/bin/#g' init.d/fdfs_storaged
sed -i 's#/usr/local/bin/#/usr/bin/#g' init.d/fdfs_trackerd
./make.sh
./make.sh install

五、storage server 安装 nginx
编译安装nginx，添加fastdfs nginx 模块
tar xf fastdfs-nginx-module_v1.16.tar.gz
vim fastdfs-nginx-module/src/config
CORE_INCS="$CORE_INCS /usr/include/fastdfs /usr/include/fastcommon/" #去掉local
添加软连接
ln -s /usr/lib64/libfastcommon.so /usr/local/lib/libfastcommon.so
ln -s /usr/lib64/libfastcommon.so /usr/lib/libfastcommon.so
ln -s /usr/lib64/libfdfsclient.so /usr/local/lib/libfdfsclient.so
ln -s /usr/lib64/libfdfsclient.so /usr/lib/libfdfsclient.so
tar xf nginx-1.7.8.tar.gz
cd nginx-1.7.8
./configure --add-module=../fastdfs-nginx-module/src/ --prefix=/usr/local/nginx --user=nobody --group=nobody --with-http_gzip_static_module --with-http_gunzip_module
make

esac
配置 nginx(添加一个server)
cp fastdfs-nginx-module/src/mod_fastdfs.conf /etc/fdfs/
cp fastdfs-5.05/conf/{anti-steal.jpg,http.conf,mime.types} /etc/fdfs/
touch /var/log/mod_fastdfs.log
chown nobody.nobody /var/log/mod_fastdfs.log
server {
listen 80;
server_name 本机IP地址;
location /G1/M00{
root /data2/;
ngx_fastdfs_module;
}
}
配置 模块配置文件 mod_fastdfs.conf
G1 组配置：
vim /etc/fdfs/mod_fastdfs.conf
connect_timeout=2
network_timeout=30
base_path=/tmp
load_fdfs_parameters_from_tracker=true
storage_sync_file_max_delay = 86400

service nginx reload
chkconfig nginx on
六、测试
客户端配置/etc/fdfs/client.conf
connect_timeout=30
network_timeout=60
base_path=/tmp
tracker_server=10.1.1.243:22122
tracker_server=10.1.1.244:22122

use_connection_pool = false
connection_pool_max_idle_time = 3600
load_fdfs_parameters_from_tracker=false
use_storage_id = false
storage_ids_filename = storage_ids.conf
http.tracker_server_port=80
客户端测试上传下载(其他命令暂时不测试，这里仅为测试服务是否正常)：
fdfs_upload_file /etc/fdfs/client.conf /etc/passwd #上传文件
G1/M00/00/00/CgEB9Vnwv1SAXm1HAAAEeivAsqE3998928
md5sum /etc/passwd
6923374d09e7f8c9a296fdf2e84764a1 /etc/passwd
fdfs_download_file /etc/fdfs/client.conf G1/M00/00/00/CgEB9Vnwv1SAXm1HAAAEeivAsqE3998928 #下载文件
md5sum CgEB9Vnwv1SAXm1HAAAEeivAsqE3998928
6923374d09e7f8c9a296fdf2e84764a1 CgEB9Vnwv1SAXm1HAAAEeivAsqE3998928
上传下载文件内容一致，未发生改变
上传一张图片自定义meizhi.jpg

访问效果：
#前端可以设置nginx服务器做反向代理，对后端做负载均衡，这里附上一份参考示例：
http {
include mime.types;
default_type application/octet-stream;
#设置主机名哈希表的表项长度默认 32|64|128
server_names_hash_bucket_size 128;
#设置请求缓冲区大小， 默认使用 client_header_buffer_size 来读取 header 值，
#如果 header 过大，会使用 large_client_header_buffers 来读取
client_header_buffer_size 32k;
large_client_header_buffers 4 32k;
#定义最大允许上传的文件大小
client_max_body_size 300m;
#开启高效文件传输模式， sendfile 指令指定 nginx 是否调用 sendfile 函数来输出文件，对于普通应用
设为 on，如果用来进行下载等应用磁盘 IO 重负载应用，可设置为 off，以平衡磁盘与网络 I/O 处理速度，
降低系统的负载。注意：如果图片显示不正常把这个改成 off
sendfile on;
# 防止网络堵塞
tcp_nopush on;
#长连接超时时间
keepalive_timeout 120;
#gzip 模块设置
gzip on; #开启 gzip 压缩输出
gzip_min_length 1k; #最小压缩文件大小
gzip_buffers 4 16k; #压缩缓冲区
gzip_http_version 1.0; #压缩版本（默认 1.1，前端如果是 squid2.5 请使用 1.0）
gzip_comp_level 2; #压缩等级(1~9)
gzip_types text/plain application/x-javascript text/css application/xml;
#压缩类型，默认就已经包含 text/html
gzip_vary on; #根据 HTTP 头来判断是否需要压缩
gzip_disable “MSIE[1-6].”#IE6 以下对 gzip 的支持不好， 在 IE6 下禁用 gzip
proxy_redirect off;
#当后端单台 web 服务器上也配置有多个虚拟主机时，需要使用该 Header 来区分反向代理哪个主
机名
proxy_set_header Host $http_host;
proxy_set_header X-Real-IP $remote_addr;
#后端的 Web 服务器可以通过 X-Real-IP/X-Forwarded-For 获取用户真实 IP
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
#后端服务器连接的超时时间(发起握手等候响应的超时时间)
proxy_connect_timeout 90;
#后端服务器数据回传时间(规定此时间内后端服务器必须传完所有数据)
proxy_send_timeout 90;
#等待后端服务器处理请求的时间
proxy_read_timeout 90;
#nginx 从被代理的服务器读取响应时，使用该缓冲区保存响应的开始部分，该值默认等于
proxy_buffers 设置的一块缓冲区大小，但可以被设置更小
proxy_buffer_size 16k;
#为每个连接设置缓冲区的数量为 number，每块缓冲区的大小为 size，用于保存从被
代理服务器读取的响应
proxy_buffers 4 64k;
proxy_busy_buffers_size 128k;
#在开启缓冲后端服务器响应到临时文件的功能后，设置 nginx 每次写数据到临时文件的 size(大
小)限制
proxy_temp_file_write_size 128k;
