同 Tracker，Storage 启动成功后，在base_path 下创建了data、logs目录，记录着 Storage Server 的信息。
在 store_path0/data 目录下，创建了256*256个子目录：

在tracker节点上面(由于是虚拟机，电脑性能没有那么强悍，因此客户端与tracker公用一个节点)，使用cli命令行上传文件到fastdfs
修改fastdfs客户端配置文件，vim /etc/fdfs/client.conf
# the base path to store log files
#base_path = /home/yuqing/fastdfs
base_path = /root/fastdfs/work_dir/client
# tracker_server can ocur more than once for multi tracker servers.
# the value format of tracker_server is "HOST:PORT",
# the HOST can be hostname or ip address,
# and the HOST can be dual IPs or hostnames seperated by comma,
# the dual IPS must be an inner (intranet) IP and an outer (extranet) IP,
# or two different types of inner (intranet) IPs.
# for example: 192.168.2.100,122.244.141.46:22122
# another eg.: 192.168.1.10,172.17.4.21:22122
#tracker_server = 192.168.0.196:22122
#tracker_server = 192.168.0.197:22122
tracker_server = 192.168.31.101:2212
预先上传一张图片在客户端节点：

[root@bogon client]# ll
total 44
-rw-r--r--. 1 root root 42462 Feb 19 04:39 my-****-photo.png

在客户端节点上传一张图片：
[root@bogon client]# fdfs_upload_file /etc/fdfs/client.conf my-****-photo.png
group1/M00/00/00/wKgfZF5NAsuAYchbAACl3t8kljo919.png
[root@bogon client]#
上传成功后返回文件ID号：group1/M00/00/00/wKgfZF5NAsuAYchbAACl3t8kljo919.png
从fastdfs下载文件：
[root@bogon client]# fdfs_download_file /etc/fdfs/client.conf group1/M00/00/00/wKgfZF5NBH2AMXY-AACl3t8kljo625.png
[root@bogon client]# ls

[root@bogon client]#
下载后的文件内容与之前上传的文件相同，但是文件名不是原来的文件名（文件名由storage节点根据 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生成），所以客户端需要在mysql或sqlite3中记录文件路径和前后文件名。
由于我们是一个storage节点，所以可以看到直接到192.168.31.100（storage所在节点）节点查看刚才在客户端上传的图片

查看专栏详情 立即解锁全部专栏一般来说，社区开源的项目（包括我自己写的项目，也是参照这模式），都会提供两套接口：
cli 命令行接口、api接口
命令行接口用于运维。对于fastdfs的应用来说，提供给第三方程序员的接口是api接口。
