yml根据自己的dfs服务器进行配置，大致如下:

dfs.port:  172.**.**.***:88   
dfs.port1: http://172.**.**.***:88  
dfs.connect_timeout: 1000   
dfs.network_timeout: 3000   
dfs.charset: UTF-8  
dfs.tracker_http_port: 8083   
dfs.anti_steal_token: no   
dfs.secret_key: FastDFS1111111111
dfs.tracker_server: 172.**.**.***:221220
