Comment

**1. Install Celery and Redis**:

pip install celery[redis]

**2. Configure Celery**:

# celery.py

import os
from celery import Celery

# Set the default Django settings module for the 'celery' program.
os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'your_project.settings')

app = Celery('your_project')

# Load task modules from all registered Django app configs.
app.config_from_object('django.conf:settings', namespace='CELERY')

# Set concurrency to 1 for sequential execution
app.conf.worker_concurrency = 1

# Discover tasks in all installed apps (inside tasks.py files).
app.autodiscover_tasks()
```

**3. Configure Celery in Django Settings**:

```python
# settings.py

# Celery settings
CELERY_BROKER_URL = 'redis://localhost:6379/0'
CELERY_TIMEZONE = 'UTC'

# Example periodic task schedule (runs every 10 minutes)
CELERY_BEAT_SCHEDULE = {
    'my_periodic_task': {
        'task': 'myapp.tasks.my_task_function',
        'schedule': 600,  # 10 minutes (in seconds)
    },
}
```

**4. Create a Task Function**:

```python
# myapp/tasks.py

from celery import shared_task
from datetime import datetime

@shared_task
def my_task_function():
    # Your periodic task logic here
    now = datetime.now()
    print(f"My periodic task ran at {now}")
```

**5. Start Celery Beat**:


```bash
celery -A your_project beat
```

**6. Start Celery Worker**:

In a separate terminal, start the Celery worker to execute the tasks:

```bash
celery -A LSP_System beat --loglevel=DEBUG
celery -A LSP_System worker --loglevel=info --concurrency=1

for background processing
nohup celery -A LSP_System beat --loglevel=DEBUG &
nohup celery -A LSP_System worker --loglevel=info &
  
'''You can check the logs in nohub.out or by running the tail command
tail -f nohup.out
```

pkill -f 'celery -A LSP_System worker'
pkill -f 'celery -A LSP_System beat'
