1.FastDFS介绍
1.1 什么是FastDFS
FastDFS是用c语言编写的一款开源的分布式文件系统。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。FastDFS是为互联网应用量身定做的一套分布式文件存储系统,非常适合用来存储用户图片、视频、文档等文件。
FastDFS服务端有两个角色:跟踪器(tracker)和存储节点(storage)。跟踪器主要做调度工作,在访问上起负载均衡的作用。
存储节点存储文件,完成文件管理的所有功能:存储、同步和提供存取接口,FastDFS同时对文件的meta data进行管理。所谓文件的meta data就是文件的相关属性,以键值对(key value pair)方式表示,如:width=1024,其中的key为width,value为1024。文件meta data是文件属性列表,可以包含多个键值对。
1.2 FastDFS架构
FastDFS架构包括 Tracker server和Storage server。客户端请求Tracker server进行文件上传、下载,通过Trackerserver调度最终由Storage server完成文件上传和下载。
Trackerserver作用是负载均衡和调度,通过Trackerserver在文件上传时可以根据一些策略找到Storageserver提供文件上传服务。可以将tracker称为追踪服务器或调度服务器。
Storageserver作用是文件存储,客户端上传的文件最终存储在Storage服务器上,Storage server没有实现自己的文件系统而是利用操作系统 的文件系统来管理文件。可以将storage称为存储服务器。
跟踪器和存储节点都可以由一台或多台服务器构成。跟踪器和存储节点中的服务器均可以随时增加或下线而不会影响线上服务。其中跟踪器中的所有服务器都是对等的,可以根据服务器的压力情况随时增加或减少。
为了支持大容量,存储节点(服务器)采用了分卷(或分组)的组织方式。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。
FastDFS中的文件标识分为两个部分:卷名和文件名,者缺一不可。
1.2.1 Tracker 集群
FastDFS集群中的Tracker server可以有多台,Trackerserver之间是相互平等关系同时提供服务,Trackerserver不存在单点故障。客户端请求Trackerserver采用轮询方式,如果请求的tracker无法提供服务则换另一个tracker。
1.2.2 Storage集群
Storage集群采用了分组存储方式。storage集群由一个或多个组构成,集群存储总容量为集群中所有组的存储容量之和。一个组由一台或多台存储服务器组成,组内的Storage server之间是平等关系,不同组的Storageserver之间不会相互通信,同组内的Storageserver之间会相互连接进行文件同步,从而保证同组内每个storage上的文件完全一致的。一个组的存储容量为该组内存储服务器容量最小的那个,由此可见组内存储服务器的软硬件配置最好是一致的。
采用分组存储方式的好处是灵活、可控性较强。比如上传文件时,可以由客户端直接指定上传到的组也可以由tracker进行调度选择。一个分组的存储服务器访问压力较大时,可以在该组增加存储服务器来扩充服务能力(纵向扩容)。当系统容量不足时,可以增加组来扩充存储容量(横向扩容)。
1.2.3 Storage状态收集
Storage server会连接集群中所有的Tracker server,定时向他们报告自己的状态,包括磁盘剩余空间、文件同步状况、文件上传下载次数等统计信息。
1.2.4 文件上传流程
- client询问tracker上传到的storage,不需要附加参数;
- tracker返回一台可用的storage;
- client直接和storage通讯完成文件上传。
- group1 组名:文件上传后所在的storage组名称,在文件上传成功后有storage服务器返回,需要客户端自行保存。
- M00 虚拟磁盘路径:storage配置的虚拟路径,与磁盘选项store_path对应。如果配置了store_path0则是M00,如果配置了store_path1则是M01,以此类推。
- /02/44/ 数据两级目录:storage服务器在每个虚拟磁盘路径下创建的两级目录,用于存储数据文件。
- wK....sh 文件名:与文件上传时不同。是由存储服务器根据特定信息生成,文件名包含:源存储服务器IP地址、文件创建时间戳、文件大小、随机数和文件拓展名等信息。
1.2.5 文件下载流程
- client询问tracker下载文件的storage,参数为文件标识(卷名和文件名);
- tracker返回一台可用的storage;
- client直接和storage通讯完成文件下载。
tracker根据请求的文件路径即文件ID 来快速定义文件。
比如请求下边的文件:
- 通过组名tracker能够很快的定位到客户端需要访问的存储服务器组是group1,并选择合适的存储服务器提供客户端访问。
- 存储服务器根据“文件存储虚拟磁盘路径”和“数据文件两级目录”可以很快定位到文件所在目录,并根据文件名找到客户端需要访问的文件。
2. FastDFS+Nginx实现文件服务器
2.1 架构图
2.2 FastDFS安装
2.2.0 软件下载
# github地址:https://github.com/happyfish100
wget https://github.com/happyfish100/fastdfs/archive/V5.11.tar.gz
wget https://github.com/happyfish100/libfastcommon/archive/V1.0.39.tar.gz
wget https://github.com/happyfish100/fastdfs-nginx-module/archive/V1.20.tar.gz
wget https://github.com/happyfish100/fastdfs-client-java/archive/master.zip
# openresty(nginx+lua)
wget https://openresty.org/download/openresty-1.15.8.1.tar.gz
2.2.1 安装编译工具
FastDFS是C语言开发,安装FastDFS需要先将官网下载的源码进行编译,编译依赖gcc环境,如果没有gcc环境,需要安装gcc
[aaa@qq.com ~]$ sudo yum install -y gcc gcc-c++
[aaa@qq.com ~]$ sudo yum -y groupinstall 'Development Tools'
[aaa@qq.com ~]$ sudo yum -y install wget
2.2.2 安装libevent
若安装了桌面图形界面,就不需要安装;FastDFS依赖libevent库,需要安装:
[aaa@qq.com ~]$ sudo yum -y install libevent
2.2.3 安装libfastcommon
libfastcommon是FastDFS官方提供的,libfastcommon包含了FastDFS运行所需要的一些基础库。
github地址:https://github.com/happyfish100/libfastcommon/
[aaa@qq.com ~]$ sudo wget https://github.com/happyfish100/libfastcommon/archive/master.zip
[aaa@qq.com ~]$ sudo unzip master.zip
[aaa@qq.com ~]$ sudo cd libfastcommon-master
[aaa@qq.com ~]$ sudo ./make.sh
[aaa@qq.com ~]$ sudo ./make.sh install
# libfastcommon安装好后会在/usr/lib64 目录下生成 libfastcommon.so 库文件
[aaa@qq.com fdfs]$ ll /usr/lib64 | grep fdfs
-rwxr-xr-x. 1 root root 316136 Jul 31 09:53 libfdfsclient.so
# 由于FastDFS程序引用/usr/lib目录所以需要将/usr/lib64下的libfdfsclient.so拷贝至/usr/lib下,若有的话则不用再操作了。
[aaa@qq.com src]$ sudo cp /usr/lib64/libfdfsclient.so /usr/lib/
[aaa@qq.com fdfs]$ ll /usr/lib | grep fdfs
-rwxr-xr-x. 1 root root 316136 Jul 31 09:53 libfdfsclient.so
2.2.4 fastdfs编译安装
官方github地址:https://github.com/happyfish100/fastdfs
[aaa@qq.com ~]$ sudo wget https://github.com/happyfish100/fastdfs/archive/V5.11.tar.gz
[aaa@qq.com ~]$ sudo tar -zxv -f V5.11.tar.gz
[aaa@qq.com ~]$ sudo cd fastdfs-5.11/
[aaa@qq.com ~]$ sudo ./make.sh
[aaa@qq.com ~]$ sudo ./make.sh install
若在[aaa@qq.com ~]$ sudo ./make.sh
这一步报错如下:
cc -Wall -D_FILE_OFFSET_BITS=64 -D_GNU_SOURCE -g -O -DDEBUG_FLAG -c -o ../common/fdfs_global.o ../common/fdfs_global.c -I../common -I/usr/include/fastcommon
../common/fdfs_global.c:20:20: fatal error: logger.h: No such file or directory
#include "logger.h"
^
compilation terminated.
make: *** [../common/fdfs_global.o] Error 1
则是因为需要先安装libfastcommon
安装成功将安装目录下的conf下的俩文件拷贝到/etc/fdfs/下
[aaa@qq.com conf]$ sudo cp /usr/local/src/fastdfs-5.11/conf/http.conf /etc/fdfs/
[aaa@qq.com conf]$ sudo cp /usr/local/src/fastdfs-5.11/conf/mime.types /etc/fdfs/
# 其余的配置文件在/etc/fdfs/目录下有sample文件,用这个修改就行了
2.2.5 fdfs_trackerd配置并启动
安装之后sample配置文件在目录/etc/fdfs下,复制一份并重命名作为配置文件使用
[aaa@qq.com ~]$ sudo cp tracker.conf.sample tracker.conf
修改配置文件: /etc/fdfs/tracker.conf,修改路径到/opt/fdfs_data目录。
[aaa@qq.com fdfs]$ sudo mkdir -p /opt/{fastdfs,fdfs_storage}
[aaa@qq.com fdfs]$ sudo vim tracker.conf
# the base path to store data and log files
#base_path=/home/yuqing/fastdfs
base_path=/opt/fastdfs
# HTTP port on this tracker server
#http.server_port=8080
http.server_port=80
启动,查看端口号
[aaa@qq.com ~]$ sudo /usr/bin/fdfs_trackerd /etc/fdfs/tracker.conf start
[aaa@qq.com fdfs_data]$ ps -ef | grep fdfs
root 2397 1 0 10:23 ? 00:00:00 /usr/bin/fdfs_trackerd /etc/fdfs/tracker.conf start

注意:在/opt/fdfs_data目录下生成两个目录, 一个是数据,一个是日志;
设置开机自启动,新增如下一行内容
[aaa@qq.com ~]$ sudo vim /etc/rc.d/rc.local
/usr/bin/fdfs_trackerd /etc/fdfs/tracker.conf restart
2.2.6 fdfs_storaged配置并启动
安装之后sample配置文件在目录/etc/fdfs下,复制一份并重命名作为配置文件使用
修改配置文件: /etc/fdfs/storage.conf,修改路径到/data/fdfs目录,同时配置tracker_server地址。
[aaa@qq.com ~]$ sudo cp storage.conf.sample storage.conf
[aaa@qq.com fdfs]$ sudo vim storage.conf
# the base path to store data and log files
#base_path=/home/yuqing/fastdfs
base_path=/opt/fastdfs
# store_path#, based 0, if store_path0 not exists, it's value is base_path
# the paths must be exist
#store_path0=/home/yuqing/fastdfs
store_path0=/opt/fdfs_storage
#store_path1=/home/yuqing/fastdfs2
#如果有多个挂载磁盘则定义多个store_path,如下
#store_path1=.....
#store_path2=......
# tracker_server can ocur more than once, and tracker_server format is
# "host:port", host can be hostname or ip address
tracker_server=172.21.168.119:22122 # ip使用127.0.0.1则服务启动不了
# the port of the web server on this storage server
#http.server_port=8888
http.server_port=88
/opt/fdfs_storage/data下有256个1级目录,每级目录下又有256个2级子目录,总共65536个文件,新写的文件会以hash的方式被路由到其中某个子目录下,然后将文件数据直接作为一个本地文件存储到该目录中。
启动,查看端口号
[aaa@qq.com fdfs]$ sudo /usr/bin/fdfs_storaged /etc/fdfs/storage.conf start
[aaa@qq.com fdfs]$ sudo ps -ef | grep fdfs

由于现在还没有和nginx整合无法使用http下载。
2.3 FastDFS 和nginx结合使用
2.3.1 在tracker上安装 nginx
在每个tracker上安装nginx的主要目的是做负载均衡及实现高可用。如果只有一台tracker服务器可以不配置nginx。
一个tracker对应多个storage,通过nginx对storage负载均衡;
2.3.2 在storage 上安装openresty
FastDFS版本与fastdfs-nginx-module模块版本对应问题:
FastDFS Version 5.11对应的fastdfs-nginx-module的Version 1.20
FastDFS Version 5.10对应的fastdfs-nginx-module的Version 1.19
github地址:https://github.com/happyfish100/fastdfs-nginx-module
下载fastdfs-nginx-module模块,并做相应的预处理修改
[aaa@qq.com src]$ sudo wget https://github.com/happyfish100/fastdfs-nginx-module/archive/V1.20.tar.gz
[aaa@qq.com src]$ sudo tar -zxv -f V1.20.tar.gz
[aaa@qq.com src]$ sudo cd /usr/local/src/fastdfs-nginx-module-1.20/src
[aaa@qq.com src]$ sudo vim config
把如下这两行的内容:
ngx_module_incs="/usr/local/include"
CORE_INCS="$CORE_INCS /usr/local/include"
换成:
ngx_module_incs="/usr/include/fastdfs /usr/include/fastcommon/"
CORE_INCS="$CORE_INCS /usr/include/fastdfs /usr/include/fastcommon/"
# 备注
上面这一步若不操作的话,在编译安装openresty的时候会报错:

[aaa@qq.com conf]$ sudo cp http.conf mime.types /etc/fdfs/
# 这一步若不错的话nginx启动会报错:

启动nginx:
[aaa@qq.com logs]$ sudo /usr/local/openresty/nginx/sbin/nginx
[aaa@qq.com logs]$ sudo /usr/local/openresty/nginx/sbin/nginx -s reload
# 设置nginx开机启动,增加如下内容
[aaa@qq.com logs]$ sudo vim /etc/rc.d/rc.local
# nginx start
/usr/local/nginx/sbin/nginx
开机启动综合操作:
# 在centos7中, /etc/rc.d/rc.local 文件的权限被降低了,需要给rc.local 文件增加可执行的权限
[aaa@qq.com logs]$ sudo chmod +x /etc/rc.d/rc.local
[aaa@qq.com logs]$ sudo vim /etc/rc.d/rc.local
# fastdfs start
/usr/bin/fdfs_trackerd /etc/fdfs/tracker.conf restart
/usr/bin/fdfs_storaged /etc/fdfs/storage.conf restart
# nginx start
/usr/local/openresty/nginx/sbin/nginx
2.3.4 在浏览器中访问上传到fastDFS的图片
Centos系统有防火墙,需要先关闭掉,才可以在浏览器中访问
# CentOS 7.0默认使用的是firewall作为防火墙;若没有启用iptables 作为防火墙,则使用以下方式关闭防火墙
[aaa@qq.com logs]$ sudo systemctl stop firewalld.service #停止firewall
[aaa@qq.com logs]$ sudo systemctl disable firewalld.service #禁止firewall开机启动
[aaa@qq.com logs]$ sudo firewall-cmd --state #查看默认防火墙状态(关闭后显示notrunning,开启后显示running)
# 若已经启用iptables作为防火墙,则使用以下方式关闭
[aaa@qq.com logs]$ sudo service iptables stop # 临时关闭防火墙
[aaa@qq.com logs]$ sudo chkconfig iptables off # 永久关闭防火墙
# 或者考虑防火墙放行80端口
# 使用浏览器访问图片地址:http://172.21.168.119/group1/M00/00/00/rBWod11BOECAQjjjAAOMYl1argw387_big.png
2.4 整合Java代码并解决服务器跨域问题
文件服务器与java整合是有对应的工具包的,自己可以去下载 fastdfs-client-java.jar
自己创建一个maven web项目,maven的pom.xml,如下:

跨域访问
最终的方式就是:本地的nginx代理 -代理请求-云上的nginx-然后云上的nginx代理请求最终的web项目-得到了最终的解决办法!
前端js 的url: http://127.0.0.1:8000/my-fdfs/
本地的nginx配置我监听的8000:
location /my-fdfs/ {
proxy_pass http://118.145.79.12/fastdfs/fdfs/upload/;
}
云上的nginx我监听的是80端口,所以上面代理的没写端口,
云上的nginx配置:
location /fastdfs/fdfs/upload/{
proxy_pass http://118.145.79.12:8081/fastdfs/fdfs/upload/;
}
这层代理是直接访问web项目的ip+port访问的

#func:上传文件的选组方式。
#valu:0、1或2。
# 0:表示轮询
# 1:表示指定组
# 2:表示存储负载均衡(选择剩余空间最大的组)
store_lookup=2
store_group
#func:指定上传的组,如果在应用层指定了具体的组,那么这个参数将不会起效。另外如果store_lookup如果是0或2,则此参数无效。
#valu:group1等
store_group=group1
store_server
#func:上传服务器的选择方式。(一个文件被上传后,这个storageserver就相当于这个文件的storage server源,会对同组的storage server推送这个文件达到同步效果)
#valu:0、1或2
# 0: 轮询方式(默认)
# 1: 根据ip 地址进行排序选择第一个服务器(IP地址最小者)
# 2: 根据优先级进行排序(上传优先级由storage server来设置,参数名为upload_priority),优先级值越小优先级越高。
store_server=0
store_path
#func:上传路径的选择方式。storage server可以有多个存放文件的basepath(可以理解为多个磁盘)。
#valu:
# 0: 轮流方式,多个目录依次存放文件
# 2: 存储负载均衡。选择剩余空间最大的目录存放文件(注意:剩余磁盘空间是动态的,因此存储到的目录或磁盘可能也是变化的)
store_path=0
download_server
#func:下载服务器的选择方式。
#valu:
# 0:轮询(默认)
# 1:IP最小者
# 2:优先级排序(值最小的,优先级最高。)
download_server=0
reserved_storage_space
#func:保留空间值。如果某个组中的某个服务器的剩余*空间小于设定值,则文件不会被上传到这个组。

# G or g for gigabyte
# M or m for megabyte
# K or k for kilobyte
reserved_storage_space=1GB
log_level
#func:日志级别

allow_hosts
#func:可以连接到tracker server的ip范围。可设定多个值。
#valu
allow_hosts=
check_active_interval
#func:检测 storage server 存活的时间隔,单位为秒。
# storage server定期向trackerserver 发心跳,
# 如果tracker server在一个check_active_interval内还没有收到storageserver的一次心跳,
# 那边将认为该storage server已经下线。所以本参数值必须大于storage server配置的心跳时间间隔。
# 通常配置为storage server心跳时间间隔的2倍或3倍。
check_active_interval=120
thread_stack_size
#func:设定线程栈的大小。 线程栈越大,一个线程占用的系统资源就越多。
# 如果要启动更多的线程(V1.x对应的参数为max_connections,V2.0为work_threads),可以适当降低本参数值。
#valu:如64KB,默认值为64,tracker server线程栈不应小于64KB
thread_stack_size=64KB
storage_ip_changed_auto_adjust
#func:这个参数控制当storage server IP地址改变时,集群是否自动调整。注:只有在storage server进程重启时才完成自动调整。
#valu:true或false
storage_ip_changed_auto_adjust=true
2 同步
storage_sync_file_max_delay
#func:同组storage服务器之间同步的最大延迟时间。存储服务器之间同步文件的最大延迟时间,根据实际情况进行调整

storage_sync_file_max_delay=86400
storage_sync_file_max_time
#func:存储服务器同步一个文件需要消耗的最大时间,缺省为300s,即5分钟。
#sinc:v2.0
storage_sync_file_max_time=300
sync_log_buff_interval
#func:同步或刷新日志信息到硬盘的时间间隔。注意:tracker server 的日志不是时时写硬盘的,而是先写内存。
#valu:以秒为单位
sync_log_buff_interval=10
3 trunk 和 slot
#func:是否使用trunk文件来存储几个小文件
#valu:true或false
#sinc:v3.0
use_trunk_file=false
#func:最小slot大小
#valu:<= 4KB,默认为256字节
#sinc:v3.0
slot_min_size=256
