前言
环境centOS6.5，学习的时候请关闭防火墙(生产环境命令开放端口)
关闭命令：chkconfig iptables off 然后重启：reboot（也可以在控制台操作）
软件准备
安装gcc
命令：yum install make cmake gcc gcc-c++
部署fastdfs
安装文件路径在 /usr/local
安装libfastcommon
解压
命令：unzip libfastcommon-master.zip -d /usr/local/fast/
cd /usr/local/fast/libfastcommon-master
./make.sh
./make.sh install
ps:libfastcommon默认安装到了/usr/lib64/这个位置
软连接创建
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
安装FastDFS
解压
命令：tar -zxvf FastDFS_v5.0.5.tar.gz -C /usr/local/fast/
cd /usr/local/fast/FastDFS/
./make.sh
./make.sh install
因为FastDFS脚本服务脚本设置的bin目录为/usr/local/bin/下，但是实际我们安装在了/usr/bin/下面。所以我们需要修改fastdfs配置文件中的路径，
也就是修改这两个文件：
命令：vim /etc/init.d/fdfs_storaged
进行全局替换命令： %s+/usr/local/bin+/usr/bin
命令：vim /etc/init.d/fdfs_trackerd
进行全局替换命令： %s+/usr/local/bin+/usr/bin
配置跟踪器（trackerd）
修改配置文件
cd /etc/fdfs/
cp tracker.conf.sample tracker.conf
vim tracker.conf
修改内容：
# the base path to store data and log files
base_path=/fastdfs/tracker
创建目录：
mkdir -p /fastdfs/tracker
启动trackerd
启动命令：/etc/init.d/fdfs_trackerd start
停止命令：/etc/init.d/fdfs_trackerd stop
配置FastDFS存储（storaged）
修改配置文件
cd /etc/fdfs/
cp storage.conf.sample storage.conf
vim storage.conf
修改内容：
# the base path to store data and log files
base_path=/fastdfs/storage
# store_path#, based 0, if store_path0 not exists, it's value is base_path
# the paths must be exist
store_path0=/fastdfs/storage
# tracker_server can ocur more than once, and tracker_server format is
# "host:port", host can be hostname or ip address
tracker_server=192.168.1.9:22122
ps：ip地址为tracker地址
# the port of the web server on this storage server
http.server_port=80
创建存储目录：
mkdir -p /fastdfs/storage
启动存储
/etc/init.d/fdfs_storaged start
设置开机启动追踪器和存储器：（一半生产环境需要开机启动一些服务）
vim /etc/rc.d/rc.local
加入配置 ：/etc/init.d/fdfs_trackerd start
/etc/init.d/fdfs_storaged start
测试
cd /etc/fdfs/
cp client.conf.sample client.conf
修改client.conf
修改内容：
# the base path to store log files
base_path=/fastdfs/tracker
# tracker_server can ocur more than once, and tracker_server format is
# "host:port", host can be hostname or ip address
tracker_server=192.168.1.9:22122
测试上传
/usr/bin/fdfs_upload_file /etc/fdfs/client.conf /usr/local/libfastcommon-master.zip
打印：
group1/M00/00/00/wKgBCVrWd0-APnYuAAGP6hUWM6I231.zip
FastDFS与nginx整合
安装fastdfs-nginx-module
tar -zxvf fastdfs-nginx-module_v1.16.tar.gz -C /usr/local/fast/
cd fast/fastdfs-nginx-module/
修改配置文件config
vim src/config
修改前：
CORE_INCS="$CORE_INCS /usr/local/include/fastdfs /usr/local/include/fastcommon/"
修改后：
CORE_INCS="$CORE_INCS /usr/include/fastdfs /usr/include/fastcommon/"
解压nginx
下载nginx wget http://nginx.org/download/nginx-1.10.3.tar.gz
tar -zxvf nginx-1.10.3.tar.gz
fastDFS与nginx集成
cd nginx-1.10.3
./configure --add-module=/usr/local/fast/fastdfs-nginx-module/src/
如有报错请参照 nginx安装与部署，安装相关依赖
./configure --add-module=/usr/local/fast/fastdfs-nginx-module/src/
make &&make install
修改配置文件
cp /usr/local/fast/fastdfs-nginx-module/src/mod_fastdfs.conf /etc/fdfs/
vim /etc/fdfs/mod_fastdfs.conf
修改内容：
# default value is 30s
connect_timeout=10
# valid only when load_fdfs_parameters_from_tracker is true
tracker_server=192.168.1.9:22122
# set to true when uri like ${group_name}/M00/00/00/xxx, such as group1/M00/xxx
# default value is false
url_have_group_name = true
# the paths must be exist
# must same as storage.conf
store_path0=/fastdfs/storage
复制FastDFS里的2个文件
cd /usr/local/fast/FastDFS/conf/
cp http.conf mime.types /etc/fdfs/
建立软连接
ln -s /fastdfs/storage/data/ /fastdfs/storage/data/M00
修改nginx配置
vim /usr/local/nginx/conf/nginx.conf
listen 80;
server_name localhost;
location ~/group([0-9])/M00{
ngx_fastdfs_module;
}
启动nginx
/usr/local/nginx/sbin/nginx
测试

java客户端调用示例
本示例基于springboot：
在pom.xml加入
<dependency>
<groupId>csource</groupId>
<artifactId>fastdfs-client-java</artifactId>
<version>1.27-SNAPSHOT</version>
</dependency>
这个包需要使用mvn命令手动打入m2仓库中，命令如下：
mvn install:install-file -Dfile=D:\baiduDown\fastdfs-client-java-1.27-SNAPSHOT.jar -DgroupId=csource -DartifactId=fastdfs-client-java -Dversion=1.27-SNAPSHOT -Dpackaging=jar
（文件地址请根据自己的jar地址更改）
在resources下创建 fdfs/fdfs_client.properties
# 连接tracker服务器超时时长
connect_timeout =10
# socket连接超时时长
network_timeout =30
# 文件内容编码
charset = UTF-8
# tracker服务器端口
http.tracker_http_port =80
http.anti_steal_token =no
http.secret_key =FastDFS1234567890
# tracker服务器IP和端口（可以写多个）
tracker_server =192.168.1.9:22122
