gunicorn.errors.HaltServer: <HaltServer 'Worker failed to boot.' 3>

[Ram]

Hi,

I followed this document and I’m hitting this error. Could you let me know what I’m missing? I tried several things the whole day and nothing has worked? Please let me know if you have any solution on this error?

Hi Issuer,

Try to run command: --preload to whatsup with worker processes and app and server.

Hi Integr,

Thank you for the answer but I don't see '--preload' option for the same command. Am I missing anything?

$ sudo systemctl --preload gunicorn.service
systemctl: unrecognized option '--preload'

$ sudo systemctl status gunicorn.service --preload
systemctl: unrecognized option '--preload'
$ sudo systemctl --help | grep preload

I changed the files as follows but the error is the same.

cat /etc/systemd/system/gunicorn.socket
[Unit]
Description=gunicorn socket

[Socket]
ListenStream=/run/gunicorn.sock
#ListenStream=/home/xx/myproject/myapp/myapp.sock

[Install]
WantedBy=sockets.target

$ cat /etc/systemd/system/gunicorn.service
[Unit]
Description=gunicorn daemon
Requires=gunicorn.socket
After=network.target

[Service]

          --workers 3 \
          --bind unix:/run/gunicorn.sock \
          myapp.wsgi:application

Wanted to know whether this is a bug specific to gunicorn?

pip show gunicorn
Name: gunicorn
Version: 20.0.2
Summary: WSGI HTTP Server for UNIX
Home-page: http://gunicorn.org
