Heya all,
For anyone stumbuling upon this:
Based on the provided logs, it appears that there are two main issues: running uWSGI as root and issues with the uWSGI configuration file.
Running uWSGI as root: It is not recommended to run uWSGI as root due to security reasons. You can add the --uid and --gid options to the uWSGI command to run it as a non-root user. You can create a new user, or use an existing user like www-data.
- uwsgi --uid www-data --gid www-data ...
Make sure the www-data user has the necessary permissions to access the required files and directories.
uWSGI configuration issues: The log says “unable to load configuration from uwsgi”. This suggests that there might be an issue with the uWSGI configuration file. Ensure that the uWSGI configuration file is in the correct location and has the correct format.
Check the path to your uWSGI configuration file (typically named uwsgi.ini). Ensure that the file exists and that uWSGI is pointing to the correct path. Also, make sure the file is readable by the user running uWSGI.
Next, check the contents of the uwsgi.ini file to ensure it’s properly configured. Here’s a sample uWSGI configuration for a Flask application:
[uwsgi]
http-timeout = 86400
module = wsgi:app
master = true
processes = 5
socket = /var/www/html/items-rest/socket.sock
chmod-socket = 664
vacuum = true
die-on-term = true
Update the module line to point to your Flask app object. If your Flask app is defined in a file named app.py, and the Flask app object is named app, then the line should be module = app:app.
After addressing these two issues, restart your uWSGI service and check if the issues are resolved. If you still encounter issues, please provide more information about your uWSGI and Nginx configurations, as well as any relevant log messages.
