-# SurfSmart
+# SurfSmart Deployment Guide for CentOS 9 Stream

-SurfSmart is a web application with a Flask backend and a React/Vite frontend.
+## Prerequisites
+- Fresh CentOS 9 Stream installation
+- Root or sudo access
+- Domain name pointed to your server (optional, for production)

-## Deployment Overview
+## Step 1: System Update and Basic Tools

-1. **System packages**
-   ```bash
-   sudo dnf install -y git python3.12 python3.12-virtualenv nodejs npm redis
-   ```
+```bash
+# Update system
+sudo dnf update -y

-2. **Clone the repository**
-   ```bash
-   git clone <repo-url> /opt/surfsmart
-   cd /opt/surfsmart
-   ```
+# Install development tools
+sudo dnf groupinstall "Development Tools" -y
+sudo dnf install -y wget curl git nano vim

-   Remove any bundled virtual environment if present:
-   ```bash
-   rm -rf backend_flask/flask
-   ```
+# Install Python 3.10 and pip
+sudo dnf install -y python3.10 python3.10-devel python3.10-pip

-3. **Create a Python virtual environment and install dependencies**
-   ```bash
-   python3.12 -m venv venv
-   source venv/bin/activate
-   pip install --upgrade pip
-   pip install -r backend_flask/requirements.txt
-   ```
+# Create Python alias
+sudo alternatives --set python3 /usr/bin/python3.10

-4. **Environment variables**
-   Create a `.env` file and define at least the following:
-   ```bash
-   MONGO_URI="mongodb+srv://<user>:<pass>@cluster.mongodb.net/?retryWrites=true&w=majority"
-   SECRET_KEY="replace_with_random_secret"
-   FRONTEND_ORIGIN="https://surfsmart.tech"
-   FLASK_CONFIG="production"
-   CELERY_BROKER_URL="redis://localhost:6379/0"
-   CELERY_RESULT_BACKEND="redis://localhost:6379/0"
-   ```
+# Install Node.js 18.x (for React frontend)
+curl -fsSL https://rpm.nodesource.com/setup_18.x | sudo bash -
+sudo dnf install -y nodejs

-5. **Systemd services**
-   See `surfsmart-backend.service` and `surfsmart-celery.service` examples in the repository root for running Gunicorn and Celery as services.
+# Install Redis (for Celery)
+sudo dnf install -y redis
+sudo systemctl enable redis
+sudo systemctl start redis

-6. **Build the React frontend**
-   ```bash
-   cd frontend_react
-   npm install
-   npm run build
-   ```
-   The build artifacts will be located in `frontend_react/dist`.
+# Install Nginx (web server)
+sudo dnf install -y nginx
+sudo systemctl enable nginx
+```

-7. **Nginx configuration**
-   Configure Nginx to serve the static frontend and proxy `/api/` requests to Gunicorn running the Flask application.
+## Step 2: MongoDB Setup

-This is only a brief outline. Adjust file paths and domain names to your environment.
+### Option A: Use MongoDB Atlas (Recommended)
+1. Create a free account at https://www.mongodb.com/cloud/atlas
+2. Create a cluster
+3. Get your connection string
+4. Whitelist your server's IP address
+
+### Option B: Install MongoDB Locally
+```bash
+# Create MongoDB repo file
+sudo tee /etc/yum.repos.d/mongodb-org-6.0.repo <<EOF
+[mongodb-org-6.0]
+name=MongoDB Repository
+baseurl=https://repo.mongodb.org/yum/redhat/9/mongodb-org/6.0/x86_64/
+gpgcheck=1
+enabled=1
+gpgkey=https://www.mongodb.org/static/pgp/server-6.0.asc
+EOF
+
+# Install MongoDB
+sudo dnf install -y mongodb-org
+sudo systemctl enable mongod
+sudo systemctl start mongod
+```
+
+## Step 3: Create Application User and Directory
+
+```bash
+# Create app user
+sudo useradd -m -s /bin/bash surfsmart
+
+# Create app directory
+sudo mkdir -p /var/www/surfsmart
+sudo chown surfsmart:surfsmart /var/www/surfsmart
+
+# Switch to app user
+sudo su - surfsmart
+cd /var/www/surfsmart
+```
+
+## Step 4: Clone and Setup the Application
+
+```bash
+# Clone your repository (replace with your actual repo URL)
+git clone https://github.com/yourusername/surfsmart.git .
+# OR if you have the files locally, upload them to /var/www/surfsmart
+
+# Create Python virtual environment
+python3.10 -m venv backend_flask/venv
+source backend_flask/venv/bin/activate
+
+# Install Python dependencies
+cd backend_flask
+pip install --upgrade pip
+pip install -r requirements.txt
+pip install gunicorn  # Production WSGI server
+
+# Create .env file from example
+cp .env.example .env
+nano .env  # Edit with your actual values
+
+# Exit from virtual environment
+deactivate
+cd ..
+```
+
+## Step 5: Frontend Build
+
+```bash
+# As surfsmart user, in /var/www/surfsmart
+cd frontend_react
+npm install
+npm run build
+
+# The built files will be in frontend_react/dist
+cd ..
+```
+
+## Step 6: Create Systemd Services
+
+Exit from surfsmart user and run as root/sudo:
+
+### 6.1 Gunicorn Service (Flask Backend)
+
+```bash
+sudo tee /etc/systemd/system/surfsmart-backend.service <<EOF
+[Unit]
+Description=SurfSmart Flask Backend
+After=network.target
+
+[Service]
+User=surfsmart
+Group=surfsmart
+WorkingDirectory=/var/www/surfsmart/backend_flask
+Environment="PATH=/var/www/surfsmart/backend_flask/venv/bin"
+Environment="PYTHONPATH=/var/www/surfsmart"
+ExecStart=/var/www/surfsmart/backend_flask/venv/bin/gunicorn -w 4 -b 127.0.0.1:5000 "myapp:create_app()"
+Restart=always
+
+[Install]
+WantedBy=multi-user.target
+EOF
+```
+
+### 6.2 Celery Worker Service
+
+```bash
+sudo tee /etc/systemd/system/surfsmart-celery.service <<EOF
+[Unit]
+Description=SurfSmart Celery Worker
+After=network.target redis.service
+
+[Service]
+User=surfsmart
+Group=surfsmart
+WorkingDirectory=/var/www/surfsmart/backend_flask
+Environment="PATH=/var/www/surfsmart/backend_flask/venv/bin"
+Environment="PYTHONPATH=/var/www/surfsmart"
+ExecStart=/var/www/surfsmart/backend_flask/venv/bin/celery -A celery_worker.celery_app:celery worker --loglevel=info
+Restart=always
+
+[Install]
+WantedBy=multi-user.target
+EOF
+```
+
+### 6.3 Enable and Start Services
+
+```bash
+sudo systemctl daemon-reload
+sudo systemctl enable surfsmart-backend
+sudo systemctl enable surfsmart-celery
+sudo systemctl start surfsmart-backend
+sudo systemctl start surfsmart-celery
+
+# Check status
+sudo systemctl status surfsmart-backend
+sudo systemctl status surfsmart-celery
+```
+
+## Step 7: Configure Nginx
+
+```bash
+sudo tee /etc/nginx/conf.d/surfsmart.conf <<EOF
+server {
+    listen 80;
+    server_name your-domain.com;  # Replace with your domain or use server IP
+
+    # Frontend (React)
+    location / {
+        root /var/www/surfsmart/frontend_react/dist;
+        try_files \$uri \$uri/ /index.html;
+    }
+
+    # Backend API proxy
+    location /api {
+        proxy_pass http://127.0.0.1:5000;
+        proxy_set_header Host \$host;
+        proxy_set_header X-Real-IP \$remote_addr;
+        proxy_set_header X-Forwarded-For \$proxy_add_x_forwarded_for;
+        proxy_set_header X-Forwarded-Proto \$scheme;
+        
+        # CORS headers (if needed)
+        add_header 'Access-Control-Allow-Origin' '*' always;
+        add_header 'Access-Control-Allow-Methods' 'GET, POST, PUT, DELETE, OPTIONS' always;
+        add_header 'Access-Control-Allow-Headers' 'Authorization, Content-Type' always;
+        
+        if (\$request_method = 'OPTIONS') {
+            return 204;
+        }
+    }
+}
+EOF
+
+# Test and reload Nginx
+sudo nginx -t
+sudo systemctl reload nginx
+```
+
+## Step 8: Configure Firewall
+
+```bash
+# Allow HTTP and HTTPS
+sudo firewall-cmd --permanent --add-service=http
+sudo firewall-cmd --permanent --add-service=https
+sudo firewall-cmd --reload
+```
+
+## Step 9: SSL Certificate (Optional but Recommended)
+
+```bash
+# Install Certbot
+sudo dnf install -y certbot python3-certbot-nginx
+
+# Get SSL certificate (replace with your domain)
+sudo certbot --nginx -d your-domain.com
+
+# Auto-renewal
+sudo systemctl enable certbot-renew.timer
+```
+
+## Step 10: Initial Setup and Testing
+
+```bash
+# Create first user via API or MongoDB directly
+# Test the application by accessing http://your-server-ip or https://your-domain.com
+
+# Monitor logs
+sudo journalctl -u surfsmart-backend -f
+sudo journalctl -u surfsmart-celery -f
+sudo tail -f /var/log/nginx/error.log
+```
+
+## Security Considerations
+
+1. **Environment Variables**: Never commit `.env` file to git
+2. **Firewall**: Only open necessary ports (80, 443)
+3. **MongoDB**: Use strong passwords and connection encryption
+4. **API Keys**: Keep all API keys secure
+5. **Updates**: Regularly update system packages
+
+## Maintenance Commands
+
+```bash
+# Restart services
+sudo systemctl restart surfsmart-backend
+sudo systemctl restart surfsmart-celery
+sudo systemctl restart nginx
+
+# View logs
+sudo journalctl -u surfsmart-backend -n 100
+sudo journalctl -u surfsmart-celery -n 100
+
+# Update application
+cd /var/www/surfsmart
+sudo -u surfsmart git pull
+sudo -u surfsmart bash -c "cd backend_flask && source venv/bin/activate && pip install -r requirements.txt"
+sudo -u surfsmart bash -c "cd frontend_react && npm install && npm run build"
+sudo systemctl restart surfsmart-backend surfsmart-celery
+```
+
+## Troubleshooting
+
+1. **Backend not starting**: Check logs with `journalctl -u surfsmart-backend`
+2. **Celery issues**: Ensure Redis is running: `sudo systemctl status redis`
+3. **MongoDB connection**: Verify connection string in `.env` file
+4. **Frontend 404**: Check Nginx configuration and dist folder
+5. **CORS errors**: Verify Nginx CORS headers configuration
+
+## Performance Optimization
+
+1. **Gunicorn Workers**: Adjust `-w` parameter based on CPU cores
+2. **MongoDB Indexes**: Create indexes for frequently queried fields
+3. **Redis Memory**: Configure Redis maxmemory policy
+4. **Nginx Caching**: Add caching headers for static assets
+
+## Backup Strategy
+
+```bash
+# Backup MongoDB (if local)
+mongodump --out /backup/mongodb/$(date +%Y%m%d)
+
+# Backup application files
+tar -czf /backup/surfsmart-$(date +%Y%m%d).tar.gz /var/www/surfsmart
+
+# Backup environment files
+cp /var/www/surfsmart/backend_flask/.env /backup/surfsmart-env-$(date +%Y%m%d)
+```

+.Synopsis
+Activate a Python virtual environment for the current PowerShell session.
+
+.Description
+Pushes the python executable for a virtual environment to the front of the
+$Env:PATH environment variable and sets the prompt to signify that you are
+in a Python virtual environment. Makes use of the command line switches as
+well as the `pyvenv.cfg` file values present in the virtual environment.
+
+.Parameter VenvDir
+Path to the directory that contains the virtual environment to activate. The
+default value for this is the parent of the directory that the Activate.ps1
+script is located within.
+
+.Parameter Prompt
+The prompt prefix to display when this virtual environment is activated. By
+default, this prompt is the name of the virtual environment folder (VenvDir)
+surrounded by parentheses and followed by a single space (ie. '(.venv) ').
+
+.Example
+Activate.ps1
+Activates the Python virtual environment that contains the Activate.ps1 script.
+
+.Example
+Activate.ps1 -Verbose
+Activates the Python virtual environment that contains the Activate.ps1 script,
+and shows extra information about the activation as it executes.
+
+.Example
+Activate.ps1 -VenvDir C:\Users\MyUser\Common\.venv
+Activates the Python virtual environment located in the specified location.
+
+.Example
+Activate.ps1 -Prompt "MyPython"
+Activates the Python virtual environment that contains the Activate.ps1 script,
+and prefixes the current prompt with the specified string (surrounded in
+parentheses) while the virtual environment is active.
+
+.Notes
+On Windows, it may be required to enable this Activate.ps1 script by setting the
+execution policy for the user. You can do this by issuing the following PowerShell
+command:
+
+PS C:\> Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope CurrentUser
+
+For more information on Execution Policies:
