Open PhpMyAdmin and Create a Database:

Example:

database name: yourusername_nextcloud

Select the Database from the left panel

Create Username - yourusername - and Grant All Privileges for the username on the database.

db username: yourusername

on: localhost

db Password: $Pwd#4646116 (Something that meets complexity requirements)

SSH to login to the server and obtain a command line prompt. Make a directory names downloads.

sudo mkdir /downloads/

Change directory to the downloads directory:

cd /downloads/ 

 
sudo wget -O nextcloud.zip https://download.nextcloud.com/server/releases/nextcloud-19.0.0.zip
