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为互联网量身定制，充分考虑了冗余备份、负载均衡、线性扩容等机制，并注重高可用、高性能等指标，使用FastDFS很容易搭建一套高性能的文件服务器集群提供文件上传、下载等服务。

虚拟机环境

安装依赖包
yum -y install pcre pcre- gcc-c++ gcc* zlib zlib-devel openssl openssl-devel gc-devel gd gd-devel git

包全部放在/usr/local/src下tar -zxvf 全部解压到/data/server/fastDFS目录下

安装libfastcommon
mkdir  -p /data/server/fastDFS
cd /data/server/fastDFS/libfastcommon-1.0.35
./make.sh
./make install

安装libevent
cd /data/server/fastDFS/libevent-2.0.20-stable 
./configure --prefix=/data/server
make clean
make
make install

创建tracker目录（安装tracker时才执行此步骤）
mkdir -p /fdfs/tracker

tracker安装（192.168.124.241）
tar -zxvf  FastDFS_v5.08.tar.gz(src解压之后移动到/data/server下)
mv FastDFS /data/server/fastDFS/
编译和安装tracker
cd /data/server/fastDFS/FastDFS
./make.sh
./make.sh install

配置tracker
cd /data/server/fastDFS/FastDFS/conf
vim tracker.conf

base_path=/fdfs/tracker   #设置tracker的数据文件和日志目录
max_connections=300      #最大连接数
work_threads=1            #工作线程数，最好和cpu核数相同
store_lookup=0     #改为轮询
http.server_port=8080     #设置http端口号  

运行
/data/server/fastDFS/FastDFS/tracker/fdfs_trackerd /data/server/fastDFS/FastDFS/conf/tracker.conf
查看tracker启动文件信息
cat /fdfs/tracker/logs/trackerd.log

确认启动成功后将tracker设置为开机自启动
vim /etc/rc.d/rc.local
在最后一行添加
/data/server/fastDFS/FastDFS/tracker/fdfs_trackerd /data/server/fastDFS/FastDFS/conf/tracker.conf

在tracker（192.168.124.241）上安装nginx

创建缓存目录
mkdir -p /var/cache/nginx/proxy_cache
安装包准备

nginx源码包
nginx-1.11.5.tar.gz
fastDFS相关插件包
ngx_cache_purge-2.3.tar.gz
pcre-8.34.tar.gz
zlib-1.2.8.tar.gz

最后如下图所示

cd /data/server/fastDFS/FastDFS/nginx-1.11.5

./configure --prefix=/data/server/fastDFS/trackerNginx --add-module=/data/server/fastDFS/ngx_cache_purge-2.3   --with-pcre=/data/server/fastDFS/pcre-8.34/ --with-zlib=/data/server/fastDFS/zlib-1.2.8

make编译
make
make install

配置nginx

修改client.conf文件注意：两台机器都要修改
vim /data/server/fastDFS/FastDFS/conf/client.conf
base_path=/fdfs/tracker #日志存放路径(tracker和storage不同)
tracker_server=192.168.124.241:22122
http.tracker_server_port=8080 #tracker服务器的http端口号

++++++++++++
在storage（192.168.124.242）中安装nginx
安装对应依赖包libfastcommon和libevent(解压放到/data/server/fastDFS目录下然后编译方法跟241机器一样)
mkdir -p /data/server/fastDFS
mkdir -p /fdfs/head/data #存放头像文件
mkdir -p /fdfs/other/data #存放其他文件
mkdir -p /fdfs/storage #storage数据节点

配置

cd /data/server/fastDFS/FastDFS/conf/

vim storage.conf
disabled=false                    #启用配置文件
max_connections=300      #最大连接数
work_threads=1            #工作线程数，最好和cpu核数相同
group_name=head                   #组名,目前我们有3个(head、item、other)
port=23000                        #设置storage的端口号(head、item、other)
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/head         #存储路径
tracker_server=192.168.41.241:22122 #tracker服务器的IP地址和端口号
http.server_port=8080             #设置http端口号

cd /fdfs/head/data
ls
如下图所示

看日志是否启动成功
/data/server/fastDFS/FastDFS/storage/fdfs_storaged /data/server/fastDFS/FastDFS/conf/storage.conf

cat /fdfs/storage/logs/storaged.log

在storage（192.168.41.242）中安装nginx
安装包准备

nginx源码包
nginx-1.11.5.tar.gz
fastDFS相关插件包
fastdfs-nginx-module_v1.16.tar.gz
pcre-8.34.tar.gz
zlib-1.2.8.tar.gz

将nginx和其他插件包全部解压到/usr/local/fastDFS/下

修改fastdfs-nginx-module/src下的config文件中的相关路径参数，否则下面的命令编译不通过。
vim /data/server/fastDFS/FastDFS/fastdfs-nginx-module/src/config
找到第4行，修改前为
CORE_INCS="$CORE_INCS /usr/local/include/fastdfs /usr/local/include/fastcommon/"
修改后为
CORE_INCS="$CORE_INCS /usr/include/fastdfs /usr/include/fastcommon/"

安装nginx
cd /data/server/fastDFS/FastDFS/nginx-1.11.5

./configure --prefix=/data/server/fastDFS/trackerNginx --add-module=/data/server/fastDFS/ngx_cache_purge-2.3   --with-pcre=/data/server/fastDFS/pcre-8.34/ --with-zlib=/data/server/fastDFS/zlib-1.2.8

make编译
make
make install
将FastDFS的nginx插件模块的配置文件copy到FastDFS配置文件目录
cp /data/server/fastDFS/fastdfs-nginx-module/src/mod_fastdfs.conf /data/server/fastDFS/FastDFS/conf/mod_fastdfs.conf

配置nginx

worker_processes  1;
events {
    worker_connections  1024;
}

http {
    include       mime.types;
    default_type  application/octet-stream;

sendfile        on;

keepalive_timeout  65;
 server {
        listen       8080;
        server_name  192.168.124.242;
location ~/head/M00 {
            root   /fdfs/head/data;
            ngx_fastdfs_module;
        }

        location ~/other/M00 {                  #组other
            root /fdfs/other/data;
            ngx_fastdfs_module;
        }
error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   html;
        }
}

配置mod_fastdfs.conf
vim /data/server/fastDFS/FastDFS/conf/mod_fastdfs.conf

connect_timeout=2
network_timeout=30
base_path=/fdfs/storage
load_fdfs_parameters_from_tracker=true
storage_sync_file_max_delay = 86400
use_storage_id = false
storage_ids_filename = storage_ids.conf
tracker_server=192.168.124.241:22122
storage_server_port=23000
group_name=group1
url_have_group_name = true
store_path_count=1
store_path0=/home/yuqing/fastdfs
log_level=info
log_filename=
response_mode=proxy
if_alias_prefix=
flv_support = true
flv_extension = flv
group_count = 2
[group1]
group_name=head
storage_server_port=23000
store_path_count=1
store_path0=/fdfs/head
[group2]
group_name=other
storage_server_port=23001
store_path_count=1
store_path0=/fdfs/other

注意：修改完成之后我们可能有个疑问，貌似我们还没有other组

cd  /data/server/fastDFS/FastDFS/conf/
cp storage.conf  ./storage_other.conf
group_name=other
port=23001
store_path0=/fdfs/other
修改完毕后启动other组的storage
/data/server/fastDFS/FastDFS/storage/fdfs_storaged  /data/server/fastDFS/FastDFS/conf/storage_other.conf restart

查看other目录是否生成了256子目录，生成了则成功
cd /fdfs/other/data/
ls
如下图所示

添加开机自启动
vim /etc/rc.d/rc.local
最后一行加入
/usr/local/fastDFS/FastDFS/storage/fdfs_storaged /data/server/fastDFS/FastDFS/conf/storage_other.conf

先运行242的nginx在运行241的nginx
两台机器关闭防火墙
systemctl stop firewalld
setenforce
执行上传命令会生成fileid
/data/server/fastDFS/FastDFS/client/fdfs_upload_file /data/server/fastDFS/FastDFS/conf/client.conf /home/test.png

浏览器访问ip:8080/fileid
