Install the current supported Plesk release on a clean server when you need a hosting control panel for websites, mail and related services. This guide replaces the old Plesk Onyx installation instructions; a new deployment should follow the current Plesk Obsidian requirements.

Check access and requirements
This procedure is for an authorized administrator of a self-managed VPS or dedicated server. Confirm your Nabtech service permits that administration and that the required Plesk licence is available. Check the official supported operating-system matrix immediately before installing. Use a clean OS without another hosting panel, a resolvable hostname, adequate resources, working DNS resolution and a tested provider console. Back up any data before changing a reused server; installing over an unrelated live stack is not a migration strategy.
01 Install current Plesk on a supported Linux server
- Connect by SSH using an authorized root session. Confirm the hostname, OS release, disk space and package-manager health. Apply appropriate base-system updates and restart first if they require it.
- Choose the supported installer method. For a standard default deployment, obtain the current one-click installer from Plesk: Review the downloaded script and source before execution. If you need component selection, use the official interactive installer instead.Command example
curl -fSL https://autoinstall.plesk.com/one-click-installer -o plesk-one-click-installer less plesk-one-click-installer sh plesk-one-click-installer - Read the installer output and resolve a prerequisite error before continuing. Do not ignore a hostname, repository or unsupported-OS error merely because an old tutorial called it a warning.
- After successful installation, open the trusted initial-login link supplied by the installer. Keep that link private. Complete the contact information, administrator password, licence and required agreement steps.
- Configure a valid TLS certificate for the panel hostname and review firewall access. Permit only the necessary administration and hosting services; restrict management access to trusted networks where practical. Do not disable the whole firewall to test the panel.
- Review updates, backup destinations, mail and DNS roles, and default hosting settings before adding production subscriptions. Create a test site first rather than immediately changing customer DNS.
Common questions
Can I install it over an existing hosting panel?
Plan a supported migration to a clean destination. Two control panels can compete for the same web, mail and database services, so an installer should not be used to convert a production server casually.
Does installation include ongoing management?
Installing software does not change your service contract. Confirm who is responsible for updates, monitoring, licences, security and restores before putting customer workloads on the server.
Confirm the expected result
Confirm HTTPS panel login, licence status and component health. Test a small website, database and any mail services you actually plan to provide. Verify an off-server backup and a controlled restore so the installation is operationally useful rather than merely displaying a dashboard.
Resolve setup problems
If installation stops, retain the exact error and installer logs, check the supported OS and repository access, and resolve the stated cause. If the panel cannot be reached, inspect the listening service and specific firewall rules through the console. Do not run several installers concurrently or install a second panel over the failed attempt.
