参考博客先搭建好文件管理系统

首先配置fastdfs-client.properties文件，这里用官方默认的：

fastdfs.connect_timeout_in_seconds = 5
fastdfs.network_timeout_in_seconds = 30
fastdfs.charset = UTF-8
fastdfs.http_anti_steal_token = false
#密钥
fastdfs.http_secret_key = FastDFS1234567890
fastdfs.http_tracker_http_port = 80
#nginx中的地址

fastdfs.connection_pool.enabled = true
fastdfs.connection_pool.max_count_per_entry = 500
fastdfs.connection_pool.max_idle_time = 3600
fastdfs.connection_pool.max_wait_time_in_ms = 1000
