Your VPS guide

1. Getting started — connect via SSH

When we hand over the VPS, you receive the IP, the root user and a password by email. Connect from your computer:

ssh root@TU_IP

On Windows use PowerShell or PuTTY; on Mac/Linux, the Terminal. First thing: update the system.

# Ubuntu / Debian
apt update && apt upgrade -y

2. Basic security

Create a user and firewall

# New user with sudo permissions
adduser miusuario
usermod -aG sudo miusuario

# UFW firewall: allow SSH, HTTP and HTTPS
apt install ufw -y
ufw allow OpenSSH
ufw allow 80,443/tcp
ufw enable

Block brute-force attacks

apt install fail2ban -y
systemctl enable --now fail2ban

3. Install a control panel

If you prefer a web interface (create domains, emails, databases with clicks), install a panel:

• CyberPanel (free, lightweight, LiteSpeed): sh <(curl https://cyberpanel.net/install.sh)
• cPanel/WHM (paid, the most complete)
• Webmin / aaPanel (free alternatives)

4. Set up your website (no panel)

LEMP stack (Nginx + PHP + MariaDB) for WordPress or other sites:

apt install nginx mariadb-server php-fpm php-mysql -y
systemctl enable --now nginx mariadb
mysql_secure_installation

Point your domain (A record) to the VPS IP and configure the Nginx block. For free HTTPS:

apt install certbot python3-certbot-nginx -y
certbot --nginx -d tudominio.com -d www.tudominio.com

5. Docker & apps (n8n, etc.)

curl -fsSL https://get.docker.com | sh

With Docker you run almost any app in minutes. Example, n8n:

docker run -d --name n8n -p 5678:5678 \
  -v n8n_data:/home/node/.n8n n8nio/n8n

6. Backups

Always keep copies. A simple backup of a folder and a database:

# Files
tar czf /root/backup_web_$(date +%F).tar.gz /var/www

# MySQL/MariaDB database
mysqldump -u root -p mibase > /root/mibase_$(date +%F).sql

Store copies off the VPS (your computer, Google Drive, S3). Automate it with cron.

7. Monitoring

# Live resources
htop            # CPU and RAM (apt install htop)
df -h           # Disk space
free -h         # Memory
journalctl -xe  # Latest system errors

If disk goes over 85-90% or RAM fills up often, it is time to upgrade your plan.

8. Troubleshooting

• Can't connect via SSH: check the IP, that the firewall allows port 22, and that fail2ban didn't block you.
• Site won't load: systemctl status nginx and check the domain points to the right IP.
• Disk full: du -sh /* | sort -h to see what's heavy; clean old logs.
