FastDFS是一个开源的，高性能的的分布式文件系统，他主要的功能包括：文件存储，同步和访问，设计基于高可用和负载均衡，FastDFS非常适用于基于文件服务的站点，例如图片分享和视频分享网站

FastDFS有两个角色：跟踪服务(tracker)和存储服务(storage)，跟踪服务控制，调度文件以负载均衡的方式访问；存储服务包括：文件存储，文件同步，提供文件访问接口，同时以key value的方式管理文件的元数据

跟踪和存储服务可以由1台或者多台服务器组成，同时可以动态的添加，删除跟踪和存储服务而不会对在线的服务产生影响，在集群中，tracker服务是对等的

存储系统由一个或多个卷组成，卷与卷之间的文件是相互独立的，所有卷的文件容量累加就是整个存储系统中的文件容量。一个卷可以由一台或多台存储服务器组成，一个卷下的存储服务器中的文件都是相同的，卷中的多台存储服务器起到了冗余备份和负载均衡的作用。在卷中增加服务器时，同步已有的文件由系统自动完成，同步完成后，系统自动将新增服务器切换到线上提供服务。当存储空间不足或即将耗尽时，可以动态添加卷。只需要增加一台或多台服务器，并将它们配置为一个新的卷，这样就扩大了存储系统的容量。

四、FastDFS上传/下载过程：

首先客户端 client 发起对 FastDFS 的文件传输动作，是通过连接到某一台 Tracker Server 的指定端口来实现的，Tracker Server 根据目前已掌握的信息，来决定选择哪一台 Storage Server ，然后将这个Storage Server 的地址等信息返回给 client，然后 client 再通过这些信息连接到这台 Storage Server，将要上传的文件传送到给 Storage Server上。

上传过程：

下载过程：

在我的项目中，一般启动2个tracker和2个storage就可以了

2、环境准备

2.1、RedHat 7 Yum源配置及关闭火墙

配置Redhat7ISO YUM源

Vi/etc/yum.repo.d/rhel7.repo

[rhel7-media]

name=rhel7-source

baseurl=file:///mnt

Enable=1

gpgcheck=1

gpgkey=file:///mnt/RPM-GPG-KEY-redhat-release

关闭防火墙：

systemctlstop firewalld

systemctldisable firewalld

2.2、安装依赖包

安装相关依赖包，如gcc、pcre、pcre-devel、zlib、zlib-devel、openssl、openssl-devel

命令：

yum -y install gcc gcc-c++ pcre pcre-devel zlibzlib-devel openssl openssl-devel

2.3、FastDFS环规划

采用两台Tracker Server和四台Storage Server搭建，实现集群配置，规划如下图：

用笔记本搭建虚拟机跑不了6台，因此改为如下规划方案：采用4台虚拟机。其中：

Tracker01即是tracker server也是storage server；

Tracker02即是tracker server也是storage server；

Storage01是storage Server。

Storage02是storage server。

分为如下两个组：

各主机/etc/hosts配置：

#Tracker01

192.168.18.2 Tracker01

192.168.18.3 Tracker02

#Storage gwmdfs1

192.168.18.4 Storage01

192.168.18.5 Storage02

#Storage gwmdfs2

192.168.18.6 Storage03

192.168.18.7 Storage04

2.4、目录规划

存储Tracker的数据文件和日志文件：

/dfsfile/fastdfs_tracker

存储Storage的数据文件和日志文件：

/dfsfile/fastdfs_storage

文件存储路径，存储上传的文件：

/dfsfile/fastdfs_storage_data

2.5、相关软件下载

相关软件包下载可到余庆作者Github官网首页下载：https://github.com/happyfish100；所下载的相关软件每台服务器都放在了/media目录下。

[root@Tracker01 media]# ls -rtl

total 19096

-rw-r--r--. 1 root root 20405 Mar 28 12:34 fastdfs-nginx-module-master.zip

-rw-r--r--. 1 root root 335132 Mar 28 12:34 fastdfs-5.09.tar.gz

-rw-r--r--. 1 root root 478841 Mar 28 12:34 libfastcommon-master.zip

-rw-r--r--. 1 root root 10535 Mar 28 12:37 ngx_cache_purge-2.1.tar.gz

3、FastDFS Tracker&Storage安装

所有节点均需要安装：

1、首先安装libfastcommon-master

# unzip libfastcommon-master

# cd libfastcommon-master

# ./make.sh

# ./make.sh install

[root@Tracker01 libfastcommon-master]# ./make.sh install

mkdir -p /usr/lib64

mkdir -p /usr/lib

install -m 755 libfastcommon.so /usr/lib64

install -m 755 libfastcommon.so /usr/lib

mkdir -p /usr/include/fastcommon

install -m 644 common_define.h hash.h chain.h logger.h base64.h shared_func.h pthread_func.h ini_file_reader.h _os_define.h sockopt.h sched_thread.h http_func.h md5.h local_ip_func.h avl_tree.h ioevent.h ioevent_loop.h fast_task_queue.h fast_timer.h process_ctrl.h fast_mblock.h connection_pool.h fast_mpool.h fast_allocator.h fast_buffer.h skiplist.h multi_skiplist.h flat_skiplist.h skiplist_common.h system_info.h fast_blocked_queue.h php7_ext_wrapper.h id_generator.h char_converter.h char_convert_loader.h /usr/include/fastcommon

libfastcommon.so 默认安装到了/usr/lib64/libfastcommon.so，但是FastDFS主程序设置的lib目录是/usr/local/lib，所以此处需要重新设置软链接。

ln -s /usr/lib64/libfastcommon.so /usr/local/lib/libfastcommon.so

2、安装fastdfs-5.09.tar.gz

# tar -zxvf fastdfs-5.09.tar.gz

# cd fastdfs-5.09

# ./make.sh

# ./make.sh install

[root@Tracker01 fastdfs-5.09]# ./make.sh install

mkdir -p /usr/bin

mkdir -p /etc/fdfs

cp -f fdfs_trackerd /usr/bin

if [ ! -f /etc/fdfs/tracker.conf.sample ]; then cp -f ../conf/tracker.conf /etc/fdfs/tracker.conf.sample; fi

if [ ! -f /etc/fdfs/storage_ids.conf.sample ]; then cp -f ../conf/storage_ids.conf /etc/fdfs/storage_ids.conf.sample; fi

mkdir -p /usr/bin

mkdir -p /etc/fdfs

cp -f fdfs_storaged /usr/bin

if [ ! -f /etc/fdfs/storage.conf.sample ]; then cp -f ../conf/storage.conf /etc/fdfs/storage.conf.sample; fi

mkdir -p /usr/bin

mkdir -p /etc/fdfs

mkdir -p /usr/lib64

mkdir -p /usr/lib

cp -f fdfs_monitor fdfs_test fdfs_test1 fdfs_crc32 fdfs_upload_file fdfs_download_file fdfs_delete_file fdfs_file_info fdfs_appender_test fdfs_appender_test1 fdfs_append_file fdfs_upload_appender /usr/bin

if [ 0 -eq 1 ]; then cp -f libfdfsclient.a /usr/lib64; cp -f libfdfsclient.a /usr/lib/;fi

if [ 1 -eq 1 ]; then cp -f libfdfsclient.so /usr/lib64; cp -f libfdfsclient.so /usr/lib/;fi

mkdir -p /usr/include/fastdfs

cp -f ../common/fdfs_define.h ../common/fdfs_global.h ../common/mime_file_parser.h ../common/fdfs_http_shared.h ../tracker/tracker_types.h ../tracker/tracker_proto.h ../tracker/fdfs_shared_func.h ../storage/trunk_mgr/trunk_shared.h tracker_client.h storage_client.h storage_client1.h client_func.h client_global.h fdfs_client.h /usr/include/fastdfs

if [ ! -f /etc/fdfs/client.conf.sample ]; then cp -f ../conf/client.conf /etc/fdfs/client.conf.sample; fi

安装完成后在/etc/fdfs目录下会生成sample配置文件，拷贝sample文件，生成正式的配置文件：

# cp client.conf.sample client.conf

# cp tracker.conf.sample tracker.conf //Tracker服务器配置

# cp storage.conf.sample storage.conf //Storage服务器配置

4、FastDFS Tracker&Storage配置

4.1、Tracker的配置

1、创建存储目录/dfsfile/fastdfs_tracker，修改/etc/fdfs/tracker.conf配置文件

[root@Tracker01 fdfs]# cat tracker.conf |grep -v "#" |grep -v "^$"|more

disabled=false

bind_addr=

port=22122

connection_pool_max_idle_time = 3600

http.server_port=80

http.check_alive_interval=30

http.check_alive_type=tcp

http.check_alive_uri=/status.html

2、启动Tracker

# ln -s /usr/bin/fdfs_trackerd /usr/local/bin

# ln -s /usr/bin/stop.sh /usr/local/bin

# ln -s /usr/bin/restart.sh /usr/local/bin

# service fdfs_trackerd start

[root@Tracker01 ~]# service fdfs_trackerd start

Reloading systemd: [ OK ]

Starting fdfs_trackerd (via systemctl): [ OK ]

# netstat -unltp |grep fdfs

[root@Tracker01 ~]# netstat -unltp | grep fdfs

tcp 0 0 0.0.0.0:22122 0.0.0.0:* LISTEN 4374/fdfs_trackerd

3、可配置成开机自动启服务。Vi /etc/rc.d/rc.local 加入service fdfs_trackerd start，并对rc.local文件设置可执行权限。

4.2、Storage的配置（涉及到组名的一定要一致不要弄错否则用ss –tlanp | grep storage查看时estab连接不上另一台storage）

1、创建目录/dfsfile/fastdfs_storage和/dfsfile/fastdfs_storage_data，并修改/etc/fdfs/storage.conf文件

disabled=false

group_name=gwmdfs1

bind_addr=

client_bind=true

port=23000

connect_timeout=30

network_timeout=60

heart_beat_interval=30

stat_report_interval=60

base_path=/home/fastdfs_storage

max_connections=256

buff_size = 256KB

sync_end_time=23:59

write_mark_file_freq=500

store_path_count=1

store_path0=/home/fastdfs_storage_data

subdir_count_per_path=256

tracker_server=192.168.18.2:22122

tracker_server=192.168.18.3:22122

log_level=info

run_by_group=

run_by_user=

sync_log_buff_interval=10

sync_binlog_buff_interval=10

sync_stat_file_interval=300

thread_stack_size=512KB

upload_priority=10

if_alias_prefix=

check_file_duplicate=0

file_signature_method=hash

key_namespace=FastDFS

keep_alive=0

use_access_log = false

rotate_access_log = false

access_log_rotate_time=00:00

rotate_error_log = false

error_log_rotate_time=00:00

rotate_access_log_size = 0

rotate_error_log_size = 0

log_file_keep_days = 0

file_sync_skip_invalid_record=false

use_connection_pool = false

connection_pool_max_idle_time = 3600

http.domain_name=

http.server_port=9999

2、启动Storage

# ln -s /usr/bin/fdfs_storaged /usr/local/bin

# ln -s /usr/bin/stop.sh /usr/local/bin

# ln -s /usr/bin/restart.sh /usr/local/bin

# service fdfs_storaged start（启动第二个storge时用该命令的绝对路径不用加start 后面接第二个storage的配置文件绝对路径）

[root@Storage02 bin]# service fdfs_storaged start

Reloading systemd: [ OK ]

Starting fdfs_storaged (via systemctl): [ OK ]

# netstat -unltp |grep fdfs

[root@Storage02 ~]# netstat -unltp |grep fdfs

tcp 0 0 0.0.0.0:23000 0.0.0.0:* LISTEN 3288/fdfs_storaged

5、FastDFS Nginx安装配置

5.1、Storage服务器配置Nginx

1、为Storage服务器安装Nginx，需要将nginx-1.8.1.tar.gz和fastdfs-nginx-module-master.zip 的安装包解压。

# tar -zxvf nginx-1.8.1.tar.gz

# unzip fastdfs-nginx-module-master.zip

2、进入Nginx-1.8.1目录下# ./configure --prefix=/usr/local/nginxs --add-module=/opt/fastdfs-nginx-module-master/src

# make

# make install

3、安装完成进入/usr/local/nginxs/目录下，如下图所示：

4、修改nginx的配置文件，进入conf目录打开nginx.conf文件

listen 9999;

location ~/gwmdfs1/M00 {

root /home/fastdfs_storage_data/data;

ngx_fastdfs_module;

}

5、拷贝配置文件到/etc/fdfs目录下，Media目录为所有软件包安装的目录。

# cp /opt/fastdfs-5.09/conf/http.conf /etc/fdfs/

# cp /opt/fastdfs-5.09/conf/mime.types /etc/fdfs/

# cp /opt/fastdfs-nginx-module-master/src/mod_fastdfs.conf /etc/fdfs/

6、修改/etc/fdfs/mod-fastdfs.conf文件

connect_timeout=2

network_timeout=30

base_path=/home/fastdfs_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=192.168.18.2:22122

tracker_server=192.168.18.3:22122

storage_server_port=23000

group_name=gwmdfs1

url_have_group_name = true

store_path_count=1

store_path0=/home/fastdfs_storage_data

log_level=info

log_filename=

response_mode=proxy

if_alias_prefix=

flv_support = true

flv_extension = flv

group_count = 2

[group1]

group_name=gwmdfs1

storage_server_port=23000

store_path_count=1

store_path0=/home/fastdfs_storage_data

[group2]

group_name=gwmdfs2

storage_server_port=23000

store_path_count=1

store_path0=/home/fastdfs_storage_data

7、建立M00至存储目录的符号连接：

#ln -s /dfsfile/fastdfs_storage_data/data /dfsfile/fastdfs_storage_data/data/M00

8、启动Nginx：

#/usr/local/nginxs/sbin/nginx

# http://192.168.18.x:9999

5.2、Tracker服务器配置Nginx

1、进入Nginx-1.8.1目录下# ./configure --prefix=/usr/local/nginxt --add-module=/media/fastdfs-nginx-module-master/src

# make

# make install

2、修改/usr/local/nginxt/conf/nginx.conf配置文件

worker_processes 1;

events {

worker_connections 1024;

}

http {

include mime.types;

default_type application/octet-stream;

sendfile on;

keepalive_timeout 65;

upstream fdfs_gwmdfs1 {

server 192.168.18.2:9999;

server 192.168.18.4:9999;

}

upstream fdfs_gwmdfs2 {

server 192.168.18.3:9999;

server 192.168.18.5:9999;

}

server {

listen 80;

server_name localhost;

location /gwmdfs1/M00 {

proxy_pass http://fdfs_gwmdfs1;

}

location /gwmdfs2/M00 {

proxy_pass http://fdfs_gwmdfs2;

}

error_page 500 502 503 504 /50x.html;

location = /50x.html {

root html;

}

3、启动nginx服务

# /usr/local/nginxt/sbin/nginx –t //启动前可测试一下nginx.conf配置是否正确。

# /usr/local/nginxt/sbin/nginx

6、FastDFS测试验证

1、修改/etc/fdfs/client.conf文件

connect_timeout=30

network_timeout=60

base_path=/home/fastdfs_storage

tracker_server=192.168.18.3:22122

tracker_server=192.168.18.2:22122

log_level=info

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

2、上传文件测试

[root@Tracker01 media]# /usr/bin/fdfs_upload_file /etc/fdfs/client.conf /media/0.PNG

gwmdfs1/M00/00/00/wKgSAljcv7-AVM2rAAA7LOqK6Ik882.PNG

[root@Tracker02 media]# /usr/bin/fdfs_upload_file /etc/fdfs/client.conf /media/1.PNG

gwmdfs1/M00/00/00/wKgSBFjcv8mAKuuRAABWJnPR5Ew861.PNG

3、通过IE查看

http://192.168.18.2/gwmdfs1/M00/00/00/wKgSBFjcv8mAKuuRAABWJnPR5Ew861.PNG

http://192.168.18.3/gwmdfs1/M00/00/00/wKgSBFjcv8mAKuuRAABWJnPR5Ew861.PNG

http://192.168.18.3/gwmdfs1/M00/00/00/wKgSAljcv7-AVM2rAAA7LOqK6Ik882.PNG

4、删除测试数据

/usr/bin/fdfs_delete_file /etc/fdfs/storage.conf appdfs1/M00/12/2C/CgUBD1x-STaACTyoAAVfNCjtfws153.png

5、监控FastDFS状态

[root@Tracker01 00]# /usr/bin/fdfs_monitor /etc/fdfs/storage.conf |more
