Leap.new AI App Deployment on RamNode VPS

Prerequisites

Before starting, ensure you have:

Server Requirements

• RamNode VPS (Ubuntu 24.04+)
• SSH access to server with sudo privileges
• Domain name pointed to VPS IP

→ View Recommended Premium VPS Plans

Application Requirements

• Leap.New application ready for deployment
• Basic Linux command line knowledge
• Understanding of web deployment basics

Initial Server Setup

Connect to your RamNode VPS and update the system:

Connect via SSH

ssh root@your-server-ip

Update System Packages

apt update && apt upgrade -y

Create a dedicated user for your application:

Create Application User

adduser leapapp
usermod -aG sudo leapapp
su - leapapp

💡 Tip: Replace "your-server-ip" with your actual RamNode VPS IP address.

Install Required Dependencies

Install Node.js, Git, and PM2 for your Leap.New application:

Install Node.js LTS

curl -fsSL https://deb.nodesource.com/setup_lts.x | sudo -E bash -
sudo apt-get install -y nodejs

Verify Node.js Installation

node --version
npm --version

Install Git and PM2

sudo apt install git -y
sudo npm install -g pm2

✅ All dependencies are now installed and ready for deployment.

Configure Firewall

Configure UFW firewall to secure your server:

Configure UFW Firewall

sudo ufw allow ssh
sudo ufw allow 80
sudo ufw allow 443
sudo ufw enable
sudo ufw status

⚠️ Warning: Make sure SSH is allowed before enabling UFW to avoid losing access!

Install and Configure Nginx

Install Nginx as a reverse proxy for your Leap.New application:

Install Nginx

sudo apt install nginx -y
sudo systemctl start nginx
sudo systemctl enable nginx

Create Nginx configuration for your domain:

Create Nginx Config File

sudo nano /etc/nginx/sites-available/leapapp

Add the following configuration (replace your-domain.com with your actual domain):

Nginx Configuration

server {
 listen 80;
 server_name your-domain.com www.your-domain.com;
 location / {
 proxy_pass http://localhost:3000;
 proxy_http_version 1.1;
 proxy_set_header Upgrade $http_upgrade;
 proxy_set_header Connection 'upgrade';
 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;
 proxy_cache_bypass $http_upgrade;
 }
}

Enable Nginx Site

sudo ln -s /etc/nginx/sites-available/leapapp /etc/nginx/sites-enabled/
sudo nginx -t
sudo systemctl reload nginx

Deploy Your Leap.New Application

Clone and prepare your Leap.New application for deployment:

Clone Application Repository

cd ~
git clone https://github.com/yourusername/your-leap-app.git
cd your-leap-app

Install NPM Dependencies

npm install

Create environment configuration:

Create Environment File

nano .env

Environment Variables Configuration

NODE_ENV=production
PORT=3000
DATABASE_URL=your_database_url
API_KEY=your_api_key
# Add other Leap.New specific variables

Build Application

npm run build

🔧 Note: Replace repository URL and environment variables with your actual values.

Set Up SSL with Let's Encrypt

Secure your application with SSL certificates:

Install Certbot

sudo apt install certbot python3-certbot-nginx -y

Obtain SSL Certificate

sudo certbot --nginx -d your-domain.com -d www.your-domain.com

🔒 Certbot will automatically configure SSL and update your Nginx configuration for HTTPS.

Start Your Application with PM2

Configure PM2 to manage your application process:

Create PM2 Ecosystem File

nano ecosystem.config.js

PM2 Configuration

module.exports = {
 apps: [{
 name: 'leap-app',
 script: 'npm',
 args: 'start',
 cwd: '/home/leapapp/your-leap-app',
 env: {
 NODE_ENV: 'production',
 PORT: 3000
 },
 instances: 'max',
 exec_mode: 'cluster',
 watch: false,
 max_memory_restart: '1G',
 error_file: './logs/err.log',
 out_file: './logs/out.log',
 log_file: './logs/combined.log',
 time: true
 }]
}

Start Application with PM2

mkdir logs
pm2 start ecosystem.config.js
pm2 save
pm2 startup

🚀 Your Leap.New application is now running with PM2 process management!

Database Setup (if required)

Set up a database if your Leap.New application requires one:

PostgreSQL Option

Install PostgreSQL

sudo apt install postgresql postgresql-contrib -y
sudo systemctl start postgresql
sudo systemctl enable postgresql

MongoDB Option

Install MongoDB

wget -qO - https://www.mongodb.org/static/pgp/server-7.0.asc | sudo apt-key add -
echo "deb [ arch=amd64,arm64 ] https://repo.mongodb.org/apt/ubuntu jammy/mongodb-org/7.0 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-7.0.list
sudo apt update && sudo apt install -y mongodb-org

Create PostgreSQL Database

sudo -u postgres psql
CREATE DATABASE leapapp_db;
CREATE USER leapapp_user WITH PASSWORD 'secure_password';
GRANT ALL PRIVILEGES ON DATABASE leapapp_db TO leapapp_user;
\q

Monitoring and Maintenance

Set up monitoring and maintenance for your application:

Create Log Rotation Config

sudo nano /etc/logrotate.d/leapapp

Logrotate Configuration

/home/leapapp/your-leap-app/logs/*.log {
 daily
 missingok
 rotate 52
 compress
 notifempty
 create 644 leapapp leapapp
 postrotate
 pm2 reloadLogs
 endscript
}

Monitor with PM2

pm2 monit
pm2 logs leap-app
pm2 status

Create automated backup script:

Create Backup Script

nano ~/backup.sh

Backup Script Content

#!/bin/bash
DATE=$(date +%Y%m%d_%H%M%S)
BACKUP_DIR="/home/leapapp/backups"
APP_DIR="/home/leapapp/your-leap-app"
mkdir -p $BACKUP_DIR
tar -czf $BACKUP_DIR/app_backup_$DATE.tar.gz -C $APP_DIR .
pg_dump -U leapapp_user -h localhost leapapp_db > $BACKUP_DIR/db_backup_$DATE.sql
find $BACKUP_DIR -name "*.tar.gz" -mtime +7 -delete

Schedule Automated Backups

chmod +x ~/backup.sh
crontab -e
# Add: 0 2 * * * /home/leapapp/backup.sh

Performance Optimization

Optimize your deployment for better performance:

Configure Nginx Compression

sudo nano /etc/nginx/nginx.conf

Gzip Configuration

gzip on;
gzip_vary on;
gzip_min_length 1024;
gzip_proxied expired no-cache no-store private must-revalidate auth;
gzip_types text/plain text/css text/xml text/javascript application/javascript application/xml+rss application/json;

Add caching headers to your Nginx server block:

Static Asset Caching

location ~* \.(jpg|jpeg|png|gif|ico|css|js)$ {
 expires 1M;
 add_header Cache-Control "public, immutable";
}

Node.js Memory Optimization

// In your ecosystem.config.js
node_args: ['--max-old-space-size=2048']

⚡ These optimizations will improve your application's loading speed and reduce server load.

Security Best Practices

Essential security practices for production deployment:

Regular Updates: Keep Ubuntu, Node.js, and all packages updated
Fail2Ban: Install fail2ban to prevent brute force attacks
SSH Keys: Disable password authentication for SSH
Firewall Rules: Only allow necessary ports (22, 80, 443)
Regular Backups: Automate backups and test restore procedures
Monitor Logs: Set up log monitoring and alerts for security events

🔒 Security Tip: Regularly audit your server, use strong passwords, and keep backups in multiple locations.
