Installing Plesk on DigitalOcean
Log in to an existing DigitalOcean account or create a new one.
Click Marketplace (under “DISCOVER” in the left navigation bar), type Plesk in the search bar, and then click the desired Plesk image: “Plesk” (which is Plesk on Ubuntu 18.04) or “Plesk (CentOS)”.
Click Create Plesk (CentOS) Droplet/Create Plesk Droplet.
Choose one of the three plans and then choose a droplet paying attention to the amount of memory it comes with.
You can choose one of the standard droplets paying attention to the amount of memory it comes with.
(Optional) Adding block storage is not necessary for Plesk to operate. You can skip this option and go to the next step.
Choose a datacenter region. If you plan to host small business websites, we recommend choosing the zone closest to their geographic location to reduce page load times for local visitors.
Additional options such as Private networking, IPv6, User data, and Monitoring are not necessary for most Plesk users. You can skip them and go to the next step.
Choose how to log in to your droplet.
Choose how many Plesk instances you want to deploy and give each one a recognizable name.
