运维使用docker部署好之后FastDFS分布式文件系统之后，提供给我接口如下：
fastdfs ?tracker 192.168.1.216 ??192.168.1.217 ?storage 192.168.1.216 ?192.168.1.217
我们只需要在配置文件中进行配置即可，然后利用客户端提供的接口通过简单的代码就可以将文件上传到分布式文件系统中
至于内部实现机制，可以参考我的另外一篇博客：分布式文件系统Fastdfs原理及部署
再次提醒在安装客户端可能会遇到各种不可控的因素，导致你上传失败，在windows中在进行安装客户端fdfs_client模块或在linux安装fdsff_client模块之后，在使用接口时都可能会出现问题，小伙伴们可以在使用时自行踩坑，我只介绍我踩坑之后最终的实现方法，即可绕过踩坑，介绍流程包括fastdfs客户端的安装、配置、django中调用相应的接口
一、客户端Fastdfs客户端的安装
因客户端模块在自行安装会出现问题，所以我提供该客户端的模块，下载链接：fast_client模块
进入fdfs_client-py-master.zip所在目录
pip install fdfs_client-py-master.zippip install mutagenpip install requests
配置文件在django项目中的存放位置：
配置文件client.conf中的内容个如下，需要做修改的部分已用红色进行标注：
# connect timeout in seconds# default value is 30sconnect_timeout=30# network timeout in seconds# default value is 30snetwork_timeout=60# the base path to store log files#客户端存放日志目录，可自行设置base_path=/Users/delron/Desktop# tracker_server can ocur more than once, and tracker_server format is# ?"host:port", host can be hostname or ip address#改成自己的ip即可，配置一个即可tracker会自行帮助我们进行任务调度tracker_server=192.168.1.217:22122#standard log level as syslog, case insensitive, value list:### emerg for emergency### alert### crit for critical### error### warn for warning### notice### info### debuglog_level=info# if use connection pool# default value is false# since V4.05use_connection_pool = false# connections whose the idle time exceeds this time will be closed# unit: second# default value is 3600# since V4.05connection_pool_max_idle_time = 3600# if load FastDFS parameters from tracker server# since V4.05# default value is falseload_fdfs_parameters_from_tracker=false# if use storage ID instead of IP address# same as tracker.conf# valid only when load_fdfs_parameters_from_tracker is false# default value is false# since V4.05use_storage_id = false# specify storage ids filename, can use relative or absolute path# same as tracker.conf# valid only when load_fdfs_parameters_from_tracker is false# since V4.05storage_ids_filename = storage_ids.conf#HTTP settingshttp.tracker_server_port=80#use "#include" directive to include HTTP other settiongs##include http.conf
二、在djaogo中使用fastdf接口实现增、删、改，下载
自定义文件，以下仅供参考：
以下是实现分布式文件系统实现文件的上传、修改、删除的代码:

可以根据自己代码实现进行相应的配置：
# fastdf配置文件设置#DEFAULT_FILE_STORAGE = ‘distributedstorage.utils.fastdfs.fdfs_storage.FastDFSStorage‘# FastDFS# fastdfs ?tracker 192.168.1.212 ??192.168.1.213 ?storage 192.168.1.212 ?192.168.1.213# FDFS_CLIENT_CONF = os.path.join(BASE_DIR, ‘utils/fastdfs/client.conf‘)FDFS_CLIENT_CONF = os.path.join(BASE_DIR, ‘client.conf‘)
在调用接口时，传递相应的参数即可完成文件的上传、下载、删除和更新，成功使用客户端进行文件的增、删、改和下载后返回文件的参数见上述代码。
