This will fetch the License agreement page and check the tick box to agree the terms and conditions and proceed to the next page.


Then comes the Settings page. Here you need to enter the admin panel login credentials with which you  can login to the Plesk control panel.


You can also set the default IP address of the server here in this page.

Next is the View Selector page. In this page you can choose the appearance of the panel as per your requirement.


Next is the Administrator information page. You just need to fill in the information asked and proceed to the next page.


Then comes the Licence key install page.  You can order, retrieve and install the License key from this page. Since I have already purchased a trial license key for this example installation, I’m proceeding with installing the license key.


Upload the license key file you received from Odin or Parallels when you purchased the key and Click OK. In the next page you can add the first domain or website in the Plesk admin panel.

I have added a test domain with the Hostname, you may replace it with the actual domain name.


Add the information and click OK. In the above screenshot I’ve used example domain, and set the user name as ‘admin’. You may change it to the desired user name as ‘admin’ would be the administrator user name.

Plesk installation process is complete and you may play around with the unlimited options it provides to get familiarise yourself with the control panel.
