How to Configure VPS Hosting on Linux Server – (Guide 2026)

To configure VPS hosting on a Linux server, deploy a fresh VPS, secure SSH access, update packages, create a sudo user, enable a firewall, harden the OS, and install a web stack (Nginx/Apache, PHP, and MariaDB/MySQL). Finally, configure DNS, obtain a free Let’s Encrypt SSL, set up backups and monitoring, and deploy your website or app.

In this step-by-step VPS setup guide, you’ll learn how to configure VPS hosting on Linux server in 2026 using industry best practices. We’ll cover security, performance, DNS, SSL, and a production-ready web stack with Nginx or Apache. The steps work on Ubuntu 24.04 LTS, Debian 12, AlmaLinux 9, and Rocky Linux 9.

What You’ll Need (Prerequisites)

• A VPS with root or sudo access (1–2 vCPU, 2–4 GB RAM for small sites)
• A domain name and registrar access (to change DNS)
• SSH client and an SSH key pair (RSA or Ed25519)
• Preferred Linux distro: Ubuntu 24.04 LTS (beginner-friendly) or Debian 12; AlmaLinux/Rocky for RHEL-like environments

Step 1: Create Your VPS and Point DNS

Pick a plan that matches your workload. For a single WordPress site or small app, 2 GB RAM and 1 vCPU is a safe baseline. Enable IPv6 if your provider supports it.

Set DNS (A/AAAA) and Reverse DNS

• Create A record: yourdomain.com → VPS IPv4
• Create AAAA record: yourdomain.com → VPS IPv6 (optional but recommended)
• Set PTR (reverse DNS) to your hostname (improves email deliverability)
• Use a short, lowercase hostname like vps1 and FQDN like vps1.yourdomain.com

Step 2: First Login and Essential Hardening

Connect via SSH and Update Packages

# From your local machine
ssh root@SERVER_IP

# Update packages (Ubuntu/Debian)
apt update && apt -y upgrade

# On AlmaLinux/Rocky
dnf -y update

Create a Sudo User and Add SSH Keys

# Create user (replace deploy with your user)
adduser deploy
usermod -aG sudo deploy     # Ubuntu/Debian
# Alma/Rocky: usermod -aG wheel deploy

# From your local machine, copy your SSH key
ssh-copy-id deploy@SERVER_IP

# Test login
ssh deploy@SERVER_IP

Secure SSH (Key-Only, Optional Port Change)

sudo nano /etc/ssh/sshd_config

# Recommended changes
PasswordAuthentication no
PermitRootLogin no
# Optional: change port (also update firewall)
# Port 2222

# Save and restart SSH
sudo systemctl restart ssh   # Ubuntu/Debian
# Alma/Rocky: sudo systemctl restart sshd

Using SSH keys and disabling root login prevents brute-force attacks. If you change the SSH port, remember to update your firewall rules and any automation scripts.

Enable a Firewall (UFW or firewalld)

On Ubuntu/Debian, UFW is simplest:

sudo apt -y install ufw
sudo ufw default deny incoming
sudo ufw default allow outgoing
sudo ufw limit OpenSSH
sudo ufw allow 80,443/tcp
# If you changed SSH port:
# sudo ufw allow 2222/tcp
sudo ufw enable
sudo ufw status

On AlmaLinux/Rocky, use firewalld:

sudo dnf -y install firewalld
sudo systemctl enable --now firewalld
sudo firewall-cmd --permanent --add-service=ssh
sudo firewall-cmd --permanent --add-service=http
sudo firewall-cmd --permanent --add-service=https
sudo firewall-cmd --reload

Install Fail2ban (Block Brute Force)

# Ubuntu/Debian
sudo apt -y install fail2ban

# Quick jail configuration
sudo tee /etc/fail2ban/jail.local >/dev/null <<'EOF'
[sshd]
enabled = true
port = ssh
maxretry = 5
bantime = 1h
findtime = 10m
EOF

sudo systemctl enable --now fail2ban

Step 3: System Basics and Performance

Set Hostname, Timezone, and Locale

# Hostname
sudo hostnamectl set-hostname vps1.yourdomain.com

# Timezone
sudo timedatectl set-timezone UTC
timedatectl status

Create a Swap File (if RAM is low)

sudo fallocate -l 2G /swapfile
sudo chmod 600 /swapfile
sudo mkswap /swapfile
sudo swapon /swapfile
echo '/swapfile none swap sw 0 0' | sudo tee -a /etc/fstab
# Optional tuning
echo 'vm.swappiness=10' | sudo tee /etc/sysctl.d/99-swappiness.conf
sudo sysctl --system

Automatic Security Updates

Keep your Linux VPS secure with unattended upgrades.

# Ubuntu/Debian
sudo apt -y install unattended-upgrades
sudo dpkg-reconfigure -plow unattended-upgrades

# Alma/Rocky (apply security updates automatically)
sudo dnf -y install dnf-automatic
sudo systemctl enable --now dnf-automatic.timer

Step 4: Install a Web Stack (LEMP or LAMP)

Option A: LEMP (Nginx, PHP-FPM, MariaDB/MySQL)

# Ubuntu/Debian
sudo apt -y install nginx mariadb-server php-fpm php-mysql php-cli php-curl php-xml php-gd php-zip php-mbstring

# Start/enable services
sudo systemctl enable --now nginx mariadb php8.3-fpm

# Secure database
sudo mysql_secure_installation

# Create a database and user
sudo mysql -u root -p -e "CREATE DATABASE appdb; CREATE USER 'appuser'@'localhost' IDENTIFIED BY 'StrongPass#2026'; GRANT ALL ON appdb.* TO 'appuser'@'localhost'; FLUSH PRIVILEGES;"

Create an Nginx server block for your domain:

sudo tee /etc/nginx/sites-available/yourdomain.com >/dev/null <<'EOF'
server {
    listen 80;
    listen [::]:80;
    server_name yourdomain.com www.yourdomain.com;

    root /var/www/yourdomain.com/public;
    index index.php index.html;

    access_log /var/log/nginx/yourdomain.access.log;
    error_log  /var/log/nginx/yourdomain.error.log;

    location / {
        try_files $uri $uri/ /index.php?$query_string;
    }

    location ~ \.php$ {
        include snippets/fastcgi-php.conf;
        fastcgi_pass unix:/run/php/php8.3-fpm.sock;
    }

    location ~* \.(png|jpg|jpeg|gif|svg|css|js|ico|webp)$ {
        expires max;
        access_log off;
    }
}
EOF

sudo mkdir -p /var/www/yourdomain.com/public
echo "<?php phpinfo(); ?>" | sudo tee /var/www/yourdomain.com/public/index.php
sudo chown -R www-data:www-data /var/www/yourdomain.com
sudo ln -s /etc/nginx/sites-available/yourdomain.com /etc/nginx/sites-enabled/
sudo nginx -t && sudo systemctl reload nginx

Option B: LAMP (Apache, PHP, MariaDB/MySQL)

# Ubuntu/Debian
sudo apt -y install apache2 libapache2-mod-php mariadb-server php php-mysql
sudo a2enmod rewrite
sudo systemctl enable --now apache2 mariadb
sudo mysql_secure_installation

Enable pretty permalinks by allowing overrides in your site’s VirtualHost (DocumentRoot and Directory blocks with AllowOverride All), then restart Apache.

Step 5: Add Free HTTPS with Let’s Encrypt (Certbot)

Use Certbot to obtain and renew SSL certificates automatically.

# Ubuntu/Debian + Nginx
sudo apt -y install certbot python3-certbot-nginx
sudo certbot --nginx -d yourdomain.com -d www.yourdomain.com
# Apache:
# sudo apt -y install certbot python3-certbot-apache
# sudo certbot --apache -d yourdomain.com -d www.yourdomain.com

# Test auto-renew
sudo certbot renew --dry-run

Certbot installs a systemd timer for renewals by default. Ensure ports 80 and 443 are open for the HTTP-01 challenge.

Step 6: Deploy Your App or WordPress

Permissions and SFTP

For Nginx on Ubuntu, the web user is typically www-data. Keep app files owned by that user or by your deploy user with group www-data. Upload via SFTP with your SSH key.

Install WordPress Quickly

cd /var/www/yourdomain.com/public
wget https://wordpress.org/latest.tar.gz
tar -xzf latest.tar.gz --strip-components=1
rm latest.tar.gz
cp wp-config-sample.php wp-config.php
# Update DB name/user/password in wp-config.php
# Set correct permissions
sudo chown -R www-data:www-data /var/www/yourdomain.com

Browse to https://yourdomain.com to complete the installer. Enforce HTTPS, enable pretty permalinks, and install a caching plugin for faster performance.

Step 7: Monitoring, Backups, and Rollbacks

System Monitoring

• Basic: top, htop, iotop, journalctl, df, free -h
• Web stack: Nginx/Apache logs, PHP-FPM slow logs
• Tools: Netdata, Uptime Kuma, Prometheus + Grafana (for growth)

Backups You Can Restore

• Snapshots at your VPS provider (fast rollback, not a full backup strategy)
• File/database backups offsite: rsync or restic to S3-compatible storage
• Automate with cron/systemd timers and test restores quarterly

Common Pitfalls and How to Avoid Them

• No SSH key: Always use key-based auth and disable root logins.
• Forgetting DNS/SSL: Point DNS early and verify A/AAAA before running Certbot.
• Open ports: Lock down with UFW/firewalld; allow only SSH, HTTP/HTTPS.
• No updates: Enable unattended upgrades and schedule maintenance windows.
• No backups: Keep offsite backups and provider snapshots for layered recovery.

Quick Reference: End-to-End Checklist

• Provision VPS, set hostname, and add DNS A/AAAA/PTR
• SSH as root, create sudo user, add keys, disable root login
• Update OS, enable firewall, install Fail2ban
• Create swap (if needed), set timezone, enable unattended updates
• Install LEMP/LAMP, create DB, configure virtual host/server block
• Obtain Let’s Encrypt SSL and verify auto-renew
• Deploy code or WordPress, set permissions, test HTTPS
• Enable monitoring, set backups and snapshot schedule

Advanced Tips for 2026

• Use PHP 8.3+ for performance and security support windows.
• Prefer MariaDB 10.6+ or MySQL 8 for better indexes and JSON support.
• Enable HTTP/2 (default with modern Nginx/Apache) and consider HTTP/3 if supported.
• On RHEL-like distros with SELinux, set correct contexts (semanage fcontext, restorecon) for webroots and PHP-FPM sockets.
• Adopt systemd timers over cron for better logging and reliability.
