MySQL is a database management system. It will organize and provide access to databases where our site can store information.
When you install MYSQL server for Ubuntu 18.04 System you need to use this command:-

Press Y for Yes when You get the confirmation message.
After installing MYSQL server you need to secure your installation bcoz at the time of installation it is not secure.
So do this first using this command:-
- $ sudo mysql_secure_installation
When you use this command your screen will show many questions and it also asked you about the password and the root password also so you set it firstly.
- VALIDATE PASSWORD PLUGIN can be used to test passwords and improve security. It checks the strength of password and allows the users to set only those passwords which are secure enough. Would you like to setup VALIDATE PASSWORD plugin?

- By default, a MySQL installation has an anonymous user, allowing anyone to log into MySQL without having to have a user account created for them. This is intended only for testing, and to make the installation go a bit smoother. You should remove them before moving into a production environment.

- Normally, root should only be allowed to connect from ‘localhost’. This ensures that someone cannot guess at the root password from the network.
