On a fresh Ubuntu 24.04 or 22.04 server (2 GB RAM, 20 GB disk minimum), run as root:
curl -fsSL https://get.5-189-171-222.sslip.io/install -o install && sudo bash install
The installer shows the license agreement, then asks for your company name, email, hostname, nameservers and admin login, and can prepare a transfer from cPanel/WHM, Plesk or DirectAdmin.
