I'm trying to start a service with supervisor, but I get an error saying
INFO spawnerr: unknown error making dispatchers for 'app_name': EACCES
Here's my supervisord.conf file:
[supervisord]
logfile=/tmp/supervisord.log
logfile_maxbytes=50MB ; change these depending on how many logs
logfile_backups=10 ; you want to keep
loglevel=info
pidfile=/tmp/supervisord.pid
nodaemon=true
minfds=1024
minprocs=200
[rpcinterface:supervisor]
supervisor.rpcinterface_factory = supervisor.rpcinterface:make_main_rpcinterface
[supervisorctl]
serverurl=unix:///tmp/supervisor.sock socket
[program:myscript]
command= python -u /home/ubuntu/appfolder/app_name.py
autostart=true
autorestart=unexpected
redirect_stderr=true
stdout_logfile=/var/log/app_name.log
I had the same issue - the celery sub program logs were being written in the logs subfolder under my app folder and turns out I had set the owner to www-user while I was debugging an issue with Nginx. I changed the owner of the app folder back to ubuntu (>> whoami)
sudo chown -R ubuntu:ubuntu /var/www/myapp/
to get it to work.
The problem is the permission for the log file With the user running supervisor you can create a "logs" folder in the same path of the supervisord.conf file and change:
logfile=/tmp/supervisord.log
to
logfile=logs/supervisord.log
I had the same issue, I recommend doing the following
Add user who runs the service. user=youruser
moving your log to a supervisor dir
from:
logfile=/tmp/supervisord.log
to:
logfile=/var/log/supervisor/supervisord.log
The same goes to you pid file
pidfile=/tmp/supervisord.pid >> pidfile=/var/run/supervisor/supervisord.pid
Make both dirs
mkdir /var/run/supervisor/
mkdir /var/log/supervisor/
then change the of the dir with
chown youuser:youuser -R /var/log/supervisor/
If this dosen't work double check who can write on you log files and pid files.
ls -l /var/log/supervisor/supervisord.log
If it still dosen't work try updating you supervisor
I get this error when running supervisord in an unprivileged Docker container, when I attempt to have supervisord run as a non-root user, using the [supervisord] [user] directive.
This caused by docker #31243 where the container is started as root then another user is created/switched-to (as per supervisord changing to non-root) and the restrictive permissions on the container's stdin/stdout/stderr via it's TTY.
My workaround is to add the non-root user to the tty group e.g. useradd -G tty supervisord, making-sure that you run with a tty e.g. docker run ... -t or Docker Compose tty: true.
the error info indicate your app "app_name" may read or write a file which has no privileges.
has you started supervisord with root, then switched to a specific user? in this case, you may create file in your "app_name" with owner of root, but the specific user may not have the right privileges.
