Getting started

Connect to the target server using root SSH, review the installation script and licensing terms, then run the product-specific installer. A valid license and supported operating system may be required.

Important: The commands below use your hosted pre.sh. Confirm its contents and product compatibility before executing it as root. The custom shadow update commands are examples and are not yet verified against the script.

STEP-BY-STEP GUIDE

License installation

The supplied reference describes license installer version 3.0 and says installation should be performed as root. Installer versions and supported platforms can change.

Installation procedure

License type	Instructions
Trial	The reference describes a 3–7 day trial, subject to provider limits and availability.
Purchased license	Paid license access and support depend on your reseller account and provider terms.

2. Confirm the operating system is supported by the selected product.

3. Inspect the hosted installation script before running it.

Download for inspection

curl -fsSL https://api.rrrhost.com/pre.sh -o /root/rrrhost-pre.sh

4. Choose a product in the license list below and use its installation command after verification.

The screenshot also mentions removing a previous license installation. No removal command has been added because running an unverified removal script could affect an existing licensed server.

FAQ & Security
