The xyz.sh wrapper adds no telemetry and does not perform hidden actions. You can read the full source on the page or with curl -fsSL xyz.sh/ .sh before running it. Piping a remote script to bash is still a risk — review the source first. The secret is printed redacted and passed only into the official installer on this machine. Docs: https://nezha.wiki/guide/agent.html

Which operating systems are supported?

Declared support: Debian, Ubuntu, CentOS, Rocky Linux, and AlmaLinux. The script detects the distribution and asks before continuing on an unrecognized OS. Syntax was checked with bash -n and ShellCheck; installer scripts have not been end-to-end verified on every listed distribution.

Yes. Run it as root or via sudo bash. The script exits with a message if it is not root.

How do I uninstall it?

curl -fsSL xyz.sh/nezha | bash -s -- uninstall. That passes uninstall to the official agent installer.

Which variables are required?

NZ_SERVER and NZ_CLIENT_SECRET are required. Optional: NZ_TLS (default false) and NZ_UUID (to reuse an existing server record). Copy them from your Dashboard; do not connect with invented sample values.

Install the Nezha Agent (Official Script and Environment Variables)

This tutorial shows how to invoke the official Nezha agent installer with xyz.sh/nezha. Use the real connection values from your own Dashboard; do not connect with sample values from the docs.

Prepare

Copy NZ_SERVER and NZ_CLIENT_SECRET from the install command in your Nezha Dashboard. Optional: NZ_TLS, NZ_UUID. Official docs: https://nezha.wiki/guide/agent.html

Root and a supported Linux distribution are required.

Install and uninstall

curl -fsSL xyz.sh/nezha | env NZ_SERVER=host:port NZ_TLS=false NZ_CLIENT_SECRET=your_secret bash

The wrapper prints the plan with the secret redacted, downloads and previews the official script, then runs it after confirmation. The secret is passed only into the official installer on this machine.

Run curl -fsSL xyz.sh/nezha | bash -s -- uninstall, which calls the official script with uninstall.

Return to the server list in your Nezha Dashboard and check whether the host comes online. The official script prints a success message when the install finishes.
