Celery not running (Permission Denied)

Question

I'm not running a Django Project, this is just a simple python project and I want to demonize the celery. Initially I was running it in the shell. Celery sometimes hangs in between(known issue). Hence I need to restart it again and again. Therefore, I need to daemonize it, so that I can run a script that restarts the celery on its own via a cronjob.

I've looked onto various threads on SO, but with no luck.

I've created a user and group , both named as celery by following commands:-

sudo groupadd celery
sudo useradd -g celery celery

I created this file as: /etc/default/celeryd

CELERYD_NODES="w1"

CELERY_BIN="/usr/local/bin/celery"

CELERY_APP="tasks"

CELERYD_CHDIR="/home/cube26/Desktop/cube26/c26-quicklook"

CELERYD_OPTS="--time-limit=300 --concurrency=8  -Q BBC,BGR,FASTCOMPANY"

CELERY_CONFIG_MODULE="celeryconfig" #I dont know what this is for?

CELERYD_LOG_FILE="/var/log/celery/%n.log"
CELERYD_PID_FILE="/var/run/celery/%n.pid"

CELERY_CREATE_DIRS=1

CELERYD_USER="celery"
CELERYD_GROUP="celery"

Then downloaded this file and kept it inside /etc/init.d/celeryd.

Then chmod +x /etc/init.d/celeryd to make it executable.

Thats all I did.

and I'm still getting an error saying IOError: [Errno 13] Permission denied: '/var/log/celery/w1.log'

What wrong am I doing? Please help me rectify it.

Based on comments, You have wrong write permissions to log file.

Please change the ownership to celery using:

chown -R celery:celery /var/log/celery/
chown -R celery:celery /var/run/celery/

-R switch is used to change permissions recursive inside directory
