Local Setup

1. Clone the repository:

git clone https://github.com/Data-Bishop/Messaging-System-With-RABBITMQ-and-CELERY.git
cd Messaging-System-With-RABBITMQ-and-CELERY

2. Create and activate a virtual environment:

python3 -m venv venv
source venv/bin/activate

3. Install dependencies:

ngrok http 5000

AWS EC2 Deployment

1. Launch an EC2 instance (Ubuntu 20.04 LTS).

2. SSH into your EC2 instance:

ssh -i your-key-pair.pem ubuntu@your-ec2-public-dns

3. Update and install dependencies:

sudo apt update && sudo apt upgrade -y
sudo apt install python3-pip python3-venv nginx rabbitmq-server redis-server -y
sudo snap install ngrok

4. Transfer project files:

scp -i your-key-pair.pem -r ./* ubuntu@your-ec2-public-dns:/home/ubuntu/messaging_system

5. Set up the project environment:

cd messaging_system
python3 -m venv venv
source venv/bin/activate
pip install -r requirements.txt

6. Configure Nginx:

• Edit /etc/nginx/sites-available/messaging_system
• Create symlink: sudo ln -s /etc/nginx/sites-available/messaging_system /etc/nginx/sites-enabled

7. Test and restart Nginx:

sudo nginx -t
sudo systemctl restart nginx

8. Set up logging:

sudo touch /var/log/messaging_system.log
sudo chown ubuntu:ubuntu /var/log/messaging_system.log
sudo chmod 644 /var/log/messaging_system.log

9. Start the Flask application:

nohup python3 app.py > app.log 2>&1 &

10. Start Celery worker:

nohup celery -A celery_worker.celery worker --loglevel=info > celery.log 2>&1 &

11. Set up ngrok:

ngrok config add-authtoken YOUR_AUTHTOKEN_HERE
nohup ngrok http 5000 | tee ngrok_output.log &

12. Retrieve ngrok URL:

curl http://localhost:4040/api/tunnels
