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. BT Panel is third-party commercial software; it runs a panel service and may require a bt.cn account, with its own terms and data handling. xyz.sh does not modify the official script.

Which operating systems are supported?

Declared support: Debian 10+, Ubuntu 18.04+, CentOS / Rocky / AlmaLinux 9 (see bt.cn for the authoritative list). 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.

Why does it need a terminal?

BT's installer asks interactive questions (such as whether to continue); without a terminal it cannot, so xyz.sh tells you to run it from an SSH session or with bash <(curl -fsSL xyz.sh/bt).

BT Panel (Baota) Installation Tutorial

This tutorial shows how to install BT Panel through its official script with xyz.sh/bt.

Prerequisites

A fresh VPS (do not mix with other panels), root, at least 1 GB RAM.

Allow the panel port (shown at the end) and 80/443 in your security group.

Steps

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

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

Check the official URL and SHA256, type y, then follow the official prompts.

Stable edition: curl -fsSL xyz.sh/bt | bash -s -- --stable

Download and preview only: curl -fsSL xyz.sh/bt | bash -s -- --dry-run

How to verify

At the end the official installer prints the panel URL, user name and password. Run bt default on the server to see them again.

How to undo or uninstall

BT provides an official uninstaller: wget http://download.bt.cn/install/bt-uninstall.sh && sh bt-uninstall.sh (it removes the panel and the software it installed — back up sites and databases first).
