# Plesk

> Order a VPS with Plesk, sign in to the panel and add your first site

[Plesk](https://plesk.com) is a web hosting panel published by a third party. From a single interface it manages your sites and their WordPress installations, email, databases, DNS and certificates. On an OnetSolutions VPS, it is installed for you when the server is created.

<Info>
  **Prerequisites**

  * A plan with at least 2 vCPU, 2 GB of RAM and 40 GB of storage
  * A Plesk licence after the trial period
</Info>

## Order

<Steps>
  <Step title="Pick the plan">
    Pick a plan on the [Plesk VPS](https://onetsolutions.net/en/vps/plesk) page: Plesk is already selected in the order.
  </Step>

  <Step title="Check the installation">
    At the **What do you want to install?** step, Plesk is shown on its own. Ubuntu 26.04 is chosen automatically.
  </Step>

  <Step title="Order">
    The server is created, then Plesk installs itself in fifteen to thirty minutes.
  </Step>
</Steps>

You can also install Plesk on an existing VPS by [reinstalling it](/control-panels/overview#install-a-panel-on-an-existing-vps).

## First sign-in

<Steps>
  <Step title="Open the panel">
    When the card shows **Installed**, select **Open the panel**, or open `https://<server IP address>:8443`. Your browser warns about a self-signed certificate until a domain name is configured: this is expected.
  </Step>

  <Step title="Log in as root">
    Use your server credentials: the `root` user and the password provided when the server was created.
  </Step>

  <Step title="Finish the setup">
    Plesk asks for your contact details and the licence to use, then opens on its dashboard.
  </Step>
</Steps>

## Licence

The installation starts on a trial licence. A Plesk licence is required afterwards, bought from the publisher. It is not included in your VPS plan. The edition you choose decides how many domains you may host and which extensions, such as the WordPress Toolkit, are available.

## Firewall

If you enable your VPS [firewall](/vps/firewall), allow port 8443 for the panel, 80 and 443 for your sites, and the email ports if you host mailboxes. The [Plesk documentation](https://docs.plesk.com) lists the full set.

## Troubleshooting

<AccordionGroup>
  <Accordion title="The installation shows Failed">
    Contact [support](/console/support) from the console: we will help you run the installation again. The installation details are logged on the server, in `/var/log/onetsolutions-plesk-install.log`.
  </Accordion>

  <Accordion title="The panel does not answer on port 8443">
    Check that the card status is **Installed**, then that port 8443 is allowed if the firewall is enabled.
