Here is how to install MySQL on Ubuntu 20.04 in under 2 minutes:
Step 1 - Update package list
First, update the package index on your server if you’ve not done so recently:
sudo apt update
apt update downloads the package lists from the repositories and updates
them to get information on the newest versions of packages and their
dependencies. It will do this for all repositories and PPAs.
Step 2 - Install the MySQL package
Now, install the mysql-server package:
sudo apt install mysql-server
Step 3 (optional) - Make sure the server is running
To make sure that the MySQL server is running in the background, execute the following command:
sudo systemctl start mysql.service
That’s it
You have successfully installed MySQL on your Ubuntu system. Now you may want to
secure it by running the mysql_secure_installation script that comes with the
installation package. This script will guide you through setting-up and securing
your MySQL server.
