VPS Base Setup

SSH in, update packages, configure firewall.

SSH into VPS#

ssh root@VPS_IP
# or for AWS
ssh ubuntu@VPS_IP -i ~/.ssh/your-key.pem
 
# confirm your public IP
curl ifconfig.me

Update system packages#

sudo apt update && sudo apt upgrade -y

Firewall#

Non-AWS (DigitalOcean, Hetzner, Linode, etc.)#

sudo ufw allow OpenSSH
sudo ufw allow 80/tcp
sudo ufw allow 443/tcp
sudo ufw enable
sudo ufw status

AWS#

Skip ufw. Instead, ensure your Security Group allows inbound on ports:

• 22 (SSH)
• 80 (HTTP)
