配置Gunicorn与Django时出现No module named revamp.wsgi错误求助

Alright, let's get that Gunicorn service up and running. The error you're seeing happens because Gunicorn isn't looking in the right directory to find your Django project's WSGI module—even though the file exists, the working context is off.

Here's what to do: #

1. Update your Gunicorn systemd config
   Open your /etc/systemd/system/gunicorn.service file and adjust the WorkingDirectory path. Right now it's set to /home/muiruri_samuel/webapp, but your Django project's root (where the revamp package containing wsgi.py lives) is one level deeper. Update the config to:

   [Unit]
   Description=gunicorn daemon
   After=network.target
   
   [Service]
   User=muiruri_samuel
   Group=www-data
   WorkingDirectory=/home/muiruri_samuel/webapp/revamp
   ExecStart=/home/muiruri_samuel/webapp/djangoenv/bin/gunicorn --access-logfile - --workers 3 --bind unix:/home/muiruri_samuel/webapp/revamp/revamp.sock revamp.wsgi:application
   
   [Install]
   WantedBy=multi-user.target
   

2. Reload systemd and restart Gunicorn
   Systemd needs to pick up the config change, so run these commands:

   sudo systemctl daemon-reload
   sudo systemctl restart gunicorn
   

3. Verify the service status
   Check if the service is now running properly:

   sudo systemctl status gunicorn
   

Why this works: #

When Gunicorn starts, it uses the WorkingDirectory as its base path. Your revamp.wsgi module lives inside /home/muiruri_samuel/webapp/revamp/revamp/—so by setting the working directory to /home/muiruri_samuel/webapp/revamp, Gunicorn can properly locate the revamp Python package (which contains wsgi.py) when it tries to import revamp.wsgi.

Quick double-check: Make sure the /home/muiruri_samuel/webapp/revamp/revamp directory has an __init__.py file (it should be there by default if you created the Django project with startproject). This file tells Python that the directory is a valid importable package.
