Nginx worker process cant access config.ru

问题:

I have set up my RoR app on DO Ubuntu x64. On Nginx port 8080.

My config:

server {
  listen 8080;
 # server_name www.mydomain.com;
  passenger_enabled on;
  passenger_app_env development;
  root /home/edgars/Proj/public;
}

In Nginx log file error:

Cannot stat '/home/edgars/Proj/config.ru; This error means that the Nginx worker process (PID 18065, running as UID 33) does not have permission to access this file.

As my research from this question shows I need to ensure that Nginx user can access that path.

sudo -u www-data cd /edgars

got error :sudo: cd: command not found

sudo gpasswd -a www-data edgars

got : Adding user www-data to group edgars

But still I cant fix that error.

Any other workaround ?

Thanks in advance.

Please check the $PATH for your the user www-data. The fact that the command cd was not found, is troubling.

Also please run this command

sudo -u www-data stat /home/edgars/Proj/config.ru

ensure that your www-data user can stat the above file. This will help you understand if you set the file permissions correctly.

Also, have you enabled SElinux on your Ubuntu? If yes, please follow the instructions here.

You need to relax permissions to that the Nginx worker process can access your application directory, by making the directory group- and world-executable:

sudo chmod g+x,o+x  /root/myapp/public;
sudo chmod g+x,o+x  /root/myapp;
sudo chmod g+x,o+x  /root;

and it's done. Good Luck!
