How to Install MySQL on Ubuntu 18.04

In this post, we will learn how to install MySQL on Ubuntu 18.04

Before proceeding, the user must have sudo privileges using which you are logged in.

Installing MySQL

1) Run updates for indexing packages

$ sudo apt update

2) Install MySQL package

$ sudo apt install mysql-server

3) MySQL service will start automatically or run below command

$ sudo systemctl start mysql 

Check MySQL service status

$ sudo systemctl status mysql

Output would be like

● mysql.service - MySQL Community Server
    Loaded: loaded (/lib/systemd/system/mysql.service; enabled; vendor preset: enabled)
    Active: active (running) since Wed 2019-06-15 1635 UTC; 2min ago
  Main PID: 15745 (mysqld)
     Tasks: 30 (limit: 548)
    CGroup: /system.slice/mysql.service
            `-15745 /usr/sbin/mysqld --daemonize --pid-file=/run/mysqld/mysqld.pid

After installation Secure MySQL using below steps

$ sudo mysql_secure_installation

This command will prompt you for root password,remove anonymous users, disallow remote root login, and remove the test database and access to secure MySQL .

NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MySQL
      SERVERS IN PRODUCTION USE!  PLEASE READ EACH STEP CAREFULLY!

In order to log into MySQL to secure it, we'll need the current
password for the root user.  If you've just installed MySQL, and
you haven't set the root password yet, the password will be blank,
so you should just press enter here.

Enter current password for root (enter for none):

OK, successfully used password, moving on...

Setting the root password ensures that nobody can log into the MySQL
root user without the proper authorisation.

Set root password? [Y/n] Y

New password:
Re-enter new password:
Password updated successfully!
Reloading privilege tables..
 ... Success!

Remove anonymous users? [Y/n] y
 ... Success!

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

Disallow root login remotely? [Y/n] y
 ... Success!

By default, MariaDB comes with a database named 'test' that anyone can
access.  This is also intended only for testing, and should be removed
before moving into a production environment.

Remove test database and access to it? [Y/n] y
 - Dropping test database...
 ... Success!
 - Removing privileges on test database...
 ... Success!

Reloading the privilege tables will ensure that all changes made so far
will take effect immediately.

Reload privilege tables now? [Y/n] y
 ... Success!

Cleaning up...

All done!  If you've completed all of the above steps, your MariaDB
installation should now be secure.

Thanks for using MySQL!
