The Linux KVM VPS Setup Checklist

This checklist is designed to guide you through the critical steps of setting up and optimizing your Linux KVM VPS. Following these steps will help ensure a secure, high-performing, and stable environment for your Nepali website.

1. Initial VPS Provisioning and OS Selection

* Choose a Reliable Provider: Select a reputable VPS provider like Hosting Nepal that offers KVM virtualization, NVMe SSDs, and local support in Kathmandu. * Select Operating System (OS): For most Nepali users, Ubuntu LTS (Long Term Support) is highly recommended due to its stability, extensive documentation, and large community support. Other options include CentOS or Debian. * Resource Allocation: Determine your required CPU cores, RAM, and NVMe SSD storage based on your website's traffic, application needs (e.g., WordPress, custom e-commerce platform), and future growth projections. Start with a plan that allows for easy upgrades. * SSH Key Setup: Generate and upload an SSH key for secure, password-less authentication. This is far more secure than relying solely on passwords.

2. Basic Server Configuration and Security Hardening

* Update System Packages: Immediately after logging in via SSH, update all installed packages to their latest versions: sudo apt update && sudo apt upgrade -y. * Create a Non-Root User: Avoid using the root user for daily operations. Create a new user with sudo privileges: sudo adduser yourusername and sudo usermod -aG sudo yourusername. * Configure SSH Security: * Disable root login via SSH: Edit /etc/ssh/sshd_config and set PermitRootLogin no. * Disable password authentication (if using SSH keys): Set PasswordAuthentication no. * Change default SSH port (optional but recommended): Set Port 2222 (or any non-standard port). * Restart SSH service: sudo systemctl restart sshd. * Set Up a Firewall (UFW): Enable and configure a firewall to restrict incoming connections. For Ubuntu, UFW (Uncomplicated Firewall) is easy to use. * sudo ufw default deny incoming * sudo ufw default allow outgoing * sudo ufw allow 2222/tcp (if you changed SSH port) * sudo ufw allow http * sudo ufw allow https * sudo ufw enable * Install Fail2Ban: Protect against brute-force attacks by automatically banning malicious IPs: sudo apt install fail2ban -y. * Configure Time Zone: Set your server's time zone to Asia/Kathmandu for accurate logging and scheduling: sudo timedatectl set-timezone Asia/Kathmandu.

3. Web Server and Database Installation

* Choose a Web Server: * Nginx: Known for high performance and efficiency, excellent for static content and as a reverse proxy. sudo apt install nginx -y. * Apache: Widely used, flexible, and robust, with extensive module support. sudo apt install apache2 -y. * Install Database Server: * MySQL/MariaDB: Popular relational databases for most web applications. sudo apt install mysql-server -y. * PostgreSQL: An advanced, open-source relational database. sudo apt install postgresql -y. * Install PHP (if needed): For WordPress or other PHP-based applications, install PHP and necessary extensions. sudo apt install php-fpm php-mysql php-cli php-gd php-curl php-mbstring php-xml php-zip -y (for Nginx) or sudo apt install libapache2-mod-php php-mysql -y (for Apache). * Configure Web Server: Set up virtual hosts for your domain (.np or .com.np) and ensure proper file permissions for your web root directory.

4. Domain and DNS Configuration

* Register Domain: Ensure your .np or .com.np domain is registered and active with a Nepali registrar. * Update DNS Records: Point your domain's A record to your VPS IP address. Configure CNAME records as needed. This is done through your domain registrar's control panel or your DNS management service. * Install SSL Certificate: Secure your website with an SSL/TLS certificate. Let's Encrypt provides free certificates and is highly recommended. * sudo apt install certbot python3-certbot-nginx -y (for Nginx) or sudo apt install certbot python3-certbot-apache -y (for Apache). * sudo certbot --nginx -d yourdomain.com -d www.yourdomain.com (for Nginx) or sudo certbot --apache -d yourdomain.com -d www.yourdomain.com (for Apache).

5. Performance Tuning and Monitoring

* Optimize Web Server: Fine-tune Nginx or Apache configuration for better performance (e.g., caching, compression, worker processes). * Database Optimization: Optimize MySQL/MariaDB settings (e.g., buffer pool size, query cache) based on your application's needs. * Caching Mechanisms: Implement server-side caching (e.g., Redis, Memcached) or application-level caching (e.g., WordPress caching plugins) to reduce database load and speed up page delivery. * Content Delivery Network (CDN): Consider using a CDN for global content delivery, especially if your audience extends beyond Nepal, though for purely local traffic, a well-optimized VPS might suffice. * Monitoring Tools: Install monitoring tools like htop, glances, or Netdata to keep an eye on CPU, RAM, disk I/O, and network usage. This helps identify bottlenecks early.

6. Backup Strategy and Maintenance

* Automated Backups: Set up regular, automated backups of your entire VPS or critical data (website files, databases). Store backups off-site or on a separate storage volume. Hosting Nepal often provides integrated backup solutions. * Security Audits: Periodically review server logs, check for suspicious activity, and perform security audits. * Regular Updates: Keep your OS, web server, database, and application software updated to patch vulnerabilities and benefit from performance improvements. * Test Backups: Crucially, regularly test your backup restoration process to ensure data integrity and recovery capability.

Common Issues and Troubleshooting Tips

Even with a checklist, you might encounter issues. Here are some common problems and solutions for your Linux KVM VPS in Nepal:

1. Website Not Accessible

* Firewall: Check if UFW or other firewalls are blocking ports 80 (HTTP) and 443 (HTTPS). Use sudo ufw status. * Web Server Status: Verify Nginx or Apache is running: sudo systemctl status nginx or sudo systemctl status apache2. * DNS Propagation: DNS changes can take up to 48 hours to propagate globally. Use dig or nslookup to check your domain's A record. * Domain Registration: Ensure your .np or .com.np domain is active and correctly pointing to your VPS IP at your registrar (e.g., Mercantile Communications for .np domains).

2. Slow Website Performance

* Resource Usage: Use htop or glances to check CPU, RAM, and NVMe SSD I/O. High usage might indicate a need for more resources or application optimization. * Database Queries: Slow database queries can significantly impact performance. Enable slow query logs in MySQL/MariaDB to identify problematic queries. * Caching: Ensure caching mechanisms are properly configured and working. * Network Latency: While Hosting Nepal provides excellent local connectivity, check your own internet service provider (e.g., WorldLink, Vianet, Classic Tech, Subisu) for any local issues.

3. SSH Connection Issues

* Port Number: If you changed the default SSH port, ensure you're using the correct one (ssh -p 2222 yourusername@your_vps_ip). * Firewall: Check if your firewall is blocking the SSH port. * SSH Keys: Verify your SSH key is correctly loaded and permissions are set (chmod 600 ~/.ssh/id_rsa).

4. Email Sending Issues

* SMTP Configuration: Ensure your email server (e.g., Postfix, Exim) is correctly configured and not blocked by your VPS provider's network policies. * DNS Records: Check SPF, DKIM, and DMARC records for your domain to ensure email deliverability and prevent emails from being marked as spam.
