Rails權限被拒絕@ dir_s_mkdir

Question

當我嘗試上傳文件時，服務器上出現以下錯誤

Permission denied @ dir_s_mkdir - /var/www/noise/public/uploads/tmp/1422949577-24950-7745

我試着給777權限的public文件夾。 仍然出現錯誤

root@99atoms-staging:/var/www/noise# sudo chmod 777 /var/www/noise/
root@99atoms-staging:/var/www/noise# stat -c %a /var/www/noise/public
755
root@99atoms-staging:/var/www/noise# sudo chmod 777 /var/www/noise/public
root@99atoms-staging:/var/www/noise# stat -c %a /var/www/noise/public
777

我們需要授予訪問系統根用戶所需目錄的權限

sudo chmod 777 -R your_project_directory_to_be_access

您可以使用：

sudo chmod 777 -R /var/www/noise/public

出於安全原因，請緊記：

chmod 777賦予每個人讀取，寫入和執行的權利，對於大多數問題，這肯定是太多了。
