Rails权限被拒绝@ dir_s_mkdir

Question

When i am trying to Upload a File i am getting the following error on the server

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

I tried to give 777 permission to the public folder. Still am getting the error

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

We need to grant permission to access the required directory for the system root user

sudo chmod 777 -R your_project_directory_to_be_access

In your case you can use:

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

For security reasons, just keep in your mind:

chmod 777 gives everybody read, write and execute rights which for most problems is definitively too much.
