Service fails with 203 error

[GurdipS5]

Hi,

I have installed Netbox on Ubuntu 22. I try to start the service, but get this error:

netbox.service - NetBox WSGI Service Loaded: loaded (/etc/systemd/system/netbox.service; enabled; vendor preset: enabled) Active: activating (auto-restart) (Result: exit-code) since Fri 2024-11-15 01:10:31 UTC; 20s> Docs: https://docs.netbox.dev/ Process: 3154 ExecStart=/opt/netbox/venv/bin/gunicorn --pid /var/tmp/netbox.pid --pythonpath > Main PID: 3154 (code=exited, status=203/EXEC) CPU: 7ms

My netbox service file is as follows:

[Unit]
Description=NetBox WSGI Service
Documentation=https://docs.netbox.dev/
After=network-online.target
Wants=network-online.target

[Service]
Type=simple

User=netbox
Group=netbox
PIDFile=/var/tmp/netbox.pid
WorkingDirectory=/opt/netbox

Remove the following line if using uWSGI instead of Gunicorn

ExecStart=/opt/netbox/venv/bin/gunicorn --pid /var/tmp/netbox.pid --pythonpath /opt/netbox/netbox --config /opt/netbox/gunicorn.py netbox.wsgi

Uncomment the following line if using uWSGI instead of Gunicorn

#ExecStart=/opt/netbox/venv/bin/uwsgi --ini /opt/netbox/uwsgi.ini

Restart=on-failure
RestartSec=30
PrivateTmp=true

[Install]
WantedBy=multi-user.target

Am I mising anything?

Doing some further investigation, Gunicorn is not in this folder;

/opt/netbox/venv/bin

But seems to be installed globally. How can I install it here? I did a pip install with the requirements.txt file.

IIRC, neither gunicorn or uwsgi are configured by default to be part of netbox's current installation; you should add either one to your local_requirements.txt

Sadly, all of the information given above is wrong :-(

@a084ed22: gunicorn is in requirements.txt

# grep gunicorn /opt/netbox/requirements.txt
gunicorn==23.0.0

Therefore, gunicorn is installed in the virtualenv if you follow the standard installation instructions (i.e. run /opt/netbox/upgrade.sh)

# ls -l /opt/netbox/venv/bin/gunicorn
-rwxr-xr-x 1 root root 229 Nov  3 16:43 /opt/netbox/venv/bin/gunicorn

(The above is my Netbox 4.1.6).

@GurdipS5: If gunicorn isn't there, then you didn't follow the installation instructions properly.

I did a pip install with the requirements.txt file

You should not do that. Furthermore, if you didn't have the virtualenv activated at that point, then you will have installed the packages in the wrong place (globally, at system level) which will pollute your system.

The installation instructions tell you to run a script called upgrade.sh which prepares a fresh virtualenv and installs all the packages within it.

Code 203 from systemd simply means "unable to exec". Either /opt/netbox/venv/bin/gunicorn does not exist, or it has wrong permissions which don't allow the netbox user to run it. Check with ls -l /opt/netbox/venv/bin/gunicorn
