xyz.sh adds no telemetry and performs no hidden actions. Read the full source on the page or download it with curl -fsSL xyz.sh/ .sh first; every script has a / .sh.sha256 checksum. Piping a remote script to bash is still a risk — review the source first. 1Panel is open source (GPL-3.0) by FIT2CLOUD. xyz.sh does not modify the official script.

Which operating systems are supported?

Declared support: Debian, Ubuntu, CentOS, Rocky Linux, and AlmaLinux. The script detects the distribution and warns on an unknown one. It was tested in Docker containers of these systems (syntax, --dry-run, and whatever can run in a container; see tests/RESULTS.md); parts that need systemd, kernel modules, or the public internet still need a real VPS.

Yes. Run it as root or via sudo bash; it exits with a message otherwise. --dry-run and --status show what it would do first.

China or international edition?

By default the fit2cloud (China) mirror is used; on overseas servers add --intl for the 1panel.pro international installer.

1Panel Installation Tutorial (Official Script)

Prerequisites

Root, at least 1 GB RAM, access to Docker registries.

Allow the 1Panel port (chosen during install) in your security group.

Steps

Optional: read the source with curl -fsSL xyz.sh/1panel.sh and compare xyz.sh/1panel.sh.sha256.

As root in an SSH terminal: curl -fsSL xyz.sh/1panel | bash

Check the official URL and SHA256, type y, then set directory, port, user and password.

Overseas servers: curl -fsSL xyz.sh/1panel | bash -s -- --intl

Preview only: curl -fsSL xyz.sh/1panel | bash -s -- --dry-run

How to verify

The installer prints the panel URL with its security entrance; later, 1pctl user-info shows it and 1pctl status shows the service.

How to undo or uninstall

Run 1pctl uninstall to remove 1Panel (Docker and its containers are handled separately).
