什么是FastDFS
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(建议范围:4KB < file_size <500MB)为载体的在线服务,如相册网站、视频网站等等。
FastDFS架构
FastDFS角色
tracker server
:调度器,负责维持集群的信息,管理着所有的group和storage server。每个storage在启动之后都会连接tracker,并告知tracker自己的心跳信息。 tracker不存储数据,它管理的元数据信息全部放置在内存中,并且元数据信息是根据storage汇报的信息生成,本身不做持久化数据。storage server
:存储服务器,以group为单位,一个group中有多个存储服务器,在同一个group中,存储服务器中的数据互相同步。 每一个storage的存储对应一个目录,比如,有10个硬盘,可以设置每个硬盘的对应的目录为/data/dev1…/data/dev10。 storage在目录中存储数据的时候,会创建2级子目录,每级256个,新写的文件会以hash的方式被路由到其中某个子目录下。client
:客户端,用来上传,下载,追加,删除等数据。
上传文件
- 由client发起上传连接请求
- 由选定的tracker查找可以用的storage server
- 找到可用的storage server后,将其返回给客户端
- 上传文件
- 生成文件的fid,将client的内容写入选定的位置
- 返回fid
- 同步数据到同组内的其它节点
tracker挑选组的方式
:
- round robin
- 指定组
- 基于可用空间进行挑选,剩余可用空间大的优先
group内挑选storage server
:
- round robin
- 以ip次序,找第一个
- 以优先级排序来找
如何选择磁盘
:
- round robin
- 剩余可用空间大优先
FID
:由源头的stroage server ip,创建时间戳,大小,文件的检验码和一个随机数进行hash计算后生成,最后基于base64编码,转换为可打印字符
文件名
:当文件存储到某个子目录后,即认为该文件存储成功,接下来会为该文件生成一个文件名,文件名由group、存储目录、两级子目录、fileid、文件后缀名(由客户端指定,主要用于区分文件类型)拼接而成。
文件下载
客户端上传完文件后,会接收到服务器返回的fid,而后在次用到时,client可以根据此文件发出请求
- client向tarcker发起请求
- tracker根据文件名定位到group,并返回group内的某一个storage server 的信息给client
- client根据返回的信息发请求
- storage server查找文件,并返回给client。

http.domain_name = storage server上web server域名。通常仅针对单独部署的web server。这样URL中就能够通过域名方式来訪问storage server上的文件了 这个參数为空就是IP地址的方式。
# the port of the web server on this storage server
http.server_port = 8888
9)修改storage
配置文件,启动storage
base_path = /ydong/fastdfs
store_path0 = /data/fastdfs
tracker_server = 192.168.199.155:22122
[root@ydong fdfs]# mkdir /ydong/fastdfs -pv
mkdir: 已创建目录 "/ydong"
mkdir: 已创建目录 "/ydong/fastdfs"
[root@ydong fdfs]# /etc/init.d/
fdfs_storaged fdfs_trackerd netconsole network
[root@ydong fdfs]# /etc/init.d/fdfs_storaged start
Starting fdfs_storaged (via systemctl): [ 确定 ]
[root@ydong fdfs]# ss -tnlp | grep 23000
LISTEN 0 128 *:23000 *:* users:(("fdfs_storaged",pid=2205,fd=5))
10)client.conf
修改配置
base_path = /ydong/client/fastdfs
tracker_server = 192.168.199.155:22122
[root@ydong fdfs]# mkdir /ydong/client/fastdfs -pv
mkdir: 已创建目录 "/ydong/client"
mkdir: 已创建目录 "/ydong/client/fastdfs"
11)上传文件测试
fdfs_upload_file <config_file> <local_filename> [storage_ip:port] [store_path_index]
[root@ydong fdfs]# fdfs_upload_file ./client.conf /etc/fstab
group1/M00/00/00/wKjHm1_aKYWAcK-zAAACHW1f-yE5058476
文件名组成:
group1:组名
M00:磁盘路径
00/00:1级目录/2级目录
wKj...476:hash码
12)查看文件信息
fdfs_file_info <config_file> <file_id>
[root@ydong fdfs]# fdfs_file_info ./client.conf group1/M00/00/00/wKjHm1_aKYWAcK-zAAACHW1f-yE5058476
GET FROM SERVER: false
file type: normal
source storage id: 0
source ip address: 192.168.199.155
file create timestamp: 2020-12-16 23:36:37
file size: 541
file crc32: 1835006753 (0x6d5ffb21)
13)下载文件
fdfs_download_file <config_file> <file_id> [local_filename] [<download_offset> <download_bytes>]
fdfs_download_file ./client.conf group1/M00/00/00/wKjHm1_aKYWAcK-zAAACHW1f-yE5058476 /root/fdfs_download
[root@ydong fdfs]# cat /root/fdfs_download
