使用nginx配合fastdfs功能 Permission denied

[root@local-huajing /home/fastdfs/storage/data/00/00]# tail -f /opt/nginx/logs/error.log 
[2021-04-18 21:41:46] ERROR - file: ../fastdfs-nginx-module-master/src/common.c, line: 1101, stat file: /home/fastdfs/storage/data/00/00/wKi8YmB8NxmAfBevAAAUGEHuYlY348.png fail, errno: 13, error info: Permission denied

解决方法：对storage的存储文件夹执行755权限，原来是700，属组是nginx，nginx无访问权限造成的。
