+===== Install the PHP Modules that are Prerequisites for NextCloud installation =====
 If you plan to install NextCloud to run on a virtual host from Apache web server, then you should install the following PHP modules that are either recommended or required as prerequisites for the proper functioning of NextCloud.  Ensure that you manually enable each of these modules in the php.ini file for purposes of running NextCloud. This involves removing the appropriate #comment marks in php.ini to enable the appropriate modules. There should obviously be other PHP modules to enable for the general operation of PHP as necessary for other websites' applications running from Apache web server on this Ubuntu server.

+===== Install MySQL Database Server =====
+The apt repositories for Ubuntu 20.04 LTS contain MySQL server version 8.0.
+Install mysql-server packages for the MySQL database. Also, install the php-mysql package to use MySQL support using PHP. Use the following command to install it.
+<code>sudo apt install mysql-server php7.4-mysql</code>
+The installer will prompt for the root password. This password will work for your MySQL root user. After installing MySQL execute the following command for initial settings of MySQL server. The script will ask more questions for settings than earlier MySQL versions, such as password validation policy etc.

+===== Installing phpMyAdmin =====
+phpMyAdmin is a web interface to manage MySQL databases and user privileges.  Install phpMyAdmin on Ubuntu 20.04 LTS as follows:
+<code>sudo apt install phpmyadmin</code>
+When prompted during installation, select "Apache" as the web server running phpMyAdmin.
+When prompted to create the phpMyAdmin database, provide your admin user access details and take the remaining steps to complete the installation.

+==== Create a new admin user or new root user and password with access from any IP remotely ====
+Using SSH access to the Ubuntu Server, log into the mysql console using as the user root with the password for root that was established when installing MySQL database server on Ubuntu.  This will put us into the console mysql>
+<code>
+sudo mysql -u root -p
+</code>
+**Enter password:**
+The SSH prompt should change to the MySQL console prompt that looks like this:
+<BLOCK>mysql></BLOCK>
+Now, create a new MySQL admin/root user with all privileges including GRANT privileges and make sure that the user can login from any IP remotely rather than only having privileges from @localhost. There are 3 choices of commands in the code block below for creating a new user from the MySQL console prompt; however, only the third choice may actually allow for logging into PhpMyAdmin as a root user from any remote IP.
+<code>
+CREATE USER 'username'@'localhost' IDENTIFIED BY 'password';
+CREATE USER 'username'@'ip_address' IDENTIFIED BY 'password';
+CREATE USER 'username'@'%' IDENTIFIED BY 'password';
+</code>
+So, for example, this should work (and ensure that you are logged into the console prompt at mysql>
+<code>
+CREATE USER 'rootuser'@'%' IDENTIFIED BY 'YourComplex#54321Pwd!';
+</code>
+Now, let's grant the new user named 'rootuser' all privileges including the Grant Option, like this:
+<code>
+GRANT ALL PRIVILEGES ON *.* TO 'rootuser'@'%' WITH GRANT OPTION;
+</code>
+And lastly, run this command:
+<code>
+FLUSH PRIVILEGES;
+</code>
+Exit the MySQL console and return to the SSH user prompt, with the exit command:
+<BLOCK>mysql> exit<BLOCK>
+Now, open your web browser and log into PhpMyAdmin through a webpage on a remote device with the username 'rootuser' and the password you installed for rootuser. You should have success now.
