MySQL Installation to Ubuntu 20.04
Step 1 : Install the mysql server package.

sudo apt install mysql-server

Step 2 : Configure MySQL

sudo mysql_secure_installation

Step 2.1 : Select your Validation Policy Level — I chose 2

Step 2.2 : Enter your new password and re-type it.

Step 2.3 : The next step will give you the estimate strength of the password you chose. Simply type Y to proceed and it will remove anonymous user and test database.

Step 3 : Testing your MySQL.

To start your mysql run the command below.

sudo systemctl start mysql

Step 3.1 : Check if MySQL Server is running.

sudo systemctl status mysql

In addition you can check the current status using mysqladmin command. Just look at the Uptime.

sudo mysqladmin -p u root version

Note: root is the account you are using it may change if you create a new user.
