Question: I am getting in touch with celery and I wrote a task by following [Tutorial](https://www.digitalocean.com/community/tutorials/how-to-use-celery-with-rabbitmq-to-queue-tasks-on-an-ubuntu-vps) but somehow worker not getting up and I get following log
After entering command:

```
celery worker -A tasks -l debug

```

I get a log:

```
Running a worker with superuser privileges when the
worker accepts messages serialized with pickle is a very bad idea!

If you really want to continue then you have to set the C_FORCE_ROOT
environment variable (but please think about this before you do).

User information: uid=0 euid=0 gid=0 egid=0

```

And here is my task:

```
from celery import Celery

app = Celery('tasks', backend='amqp',broker='amqp://sanjay:**@localhost:5672//')

@app.task
def gen_prime(x):
    multiples = []
    results = []
    for i in xrange(2, x+1):
        if i not in multiples:
            results.append(i)
            for j in xrange(i*i, x+1, i):
                multiples.append(j)
    return results

```

Though in rabbitmq admin console I see some queue build up when I try to generate prime numbers in ipython console but i am not getting result back on the console.

Here is my console action:

```
>>> from tasks import gen_prime
>>> pr=gen_prime.delay(10000)
>>> pr.ready()
False
>>> 
>>> pr.ready()
False
>>> pr.ready()
False

```

I am trying to solve this one from last 3 days but I was not able to solve it.

Answer: 
Don't run celery workers as root. 

I recommend using [supervisord](https://github.com/celery/celery/tree/3.1/extra/supervisord/) to manage celery workers - you can use the `user` configuration directive to specify which user to run the celery workers as.
The error message pretty much tells you what's going on in this case. You're trying to run the worker as root (generally a bad idea due to security concerns). If you want to override this and allow it to run, you must set your environment: 

```
export C_FORCE_ROOT="true"

```

Then run the worker.

Or you can just run it as a different user, which is preferred. You can search for how to add a user. Then you simply login as that user or su and execute your worker.

Since you tagged this digital ocean, here is a link to their tutorial on how to add a user: 

<https://www.digitalocean.com/community/tutorials/how-to-add-and-delete-users-on-ubuntu-12-04-and-centos-6>

Also, celery has some docs regarding how to daemonize your workers. I usually use the supervisord method.
