主管无法启动 Gunicorn：ENOENT

Question

I have deployed Django using gunicorn and nginx. The django project is located in a virtual environment. Everything is working perfectly when I run -

gunicorn mydjangoproject.wsgi -c gunicorn_config.py

I am running the above command inside my Django project folder containing manage.py with the virtual environment active.

However now i want to close the server terminal and want gunicorn to run automatically. For this I am using Supervisor. I have installed supervisor using apt-get and created a gunicorn.conf file in supervisor's conf.d.

But when I run supervisorctl start gunicorn I am getting a fatal error-
gunicorn: ERROR (abnormal termination)

So checked the log file and it says-

supervisor:couldn't exec root/ervirtualenvpy2/bin/gunicorn: ENOENT
child process was not spawned

My configuration file for supervisor's gunicorn.conf looks like this-

[program:gunicorn]
command = root/ervirtualenvpy2/bin/gunicorn myproject.wsgi -c     root/path/to/the/gunicorn_conf.py/file
directory = root/ervirtualenvpy2/path/to/myproject/
user=root
autorestart=true

Answer 1

Going by what you said and your config everything seems right except that you have specified relative path rather than absolute path:

see gunicorn docs

Instead it should be:

[program:gunicorn]
command = /root/ervirtualenvpy2/bin/gunicorn myproject.wsgi -c /root/path/to/the/gunicorn_conf.py/file
directory = /root/ervirtualenvpy2/path/to/myproject
user=root
autorestart=true

Also Check your gunicorn file path in env/bin/gunicorn file

In my case, I changed my env directory to another place, so please be sure with that Wrong path: #!/home/ubuntu/nikhil_project/env/bin/python Correct path: #!/home/ubuntu/env/bin/python
