502 error for deploying flask + nginx + uwsgi in centos

Posted on December 16, 2020

I was following the following tutorial: https://www.digitalocean.com/community/tutorials/how-to-serve-flask-applications-with-uwsgi-and-nginx-on-centos-7

to deploy a flask app on our hosting but I am running into a permissions issue for nginx.

The details are described in this stackoverflow post here: https://stackoverflow.com/questions/65308170/nginx-cant-read-sock-file-when-deploying-flask-uwsgi-nginx

When I run nginx as root, everything works fine so I am pretty sure it’s a permission issue but I’m not able to find out where am I going wrong.

Hi there @abhyudayasrinet,

What I could suggest is checking your Nginx error log for more information on what the actual problem is rather than the generic 502 error.

To do so, you could run the following command:

  1. sudo tail -100 /var/log/nginx/error.log

For more information on how to troubleshoot common Nginx problems, you could follow the steps here:

Feel free to post the errors here as well. Regards, Bobby
