Setting Up MySQL

We'll install and setup MySQL to be used with our Laravel application.

We'll setup MySQL so our application can connect to it. We need the following:

  1. A user
  2. A database
  3. To ensure the new user can connect to MySQL


We'll first install MySQL, version 5.7, which comes out of the box on Ubuntu 16.04.

sudo apt-get install -y mysql-server 

Then we can, optionally, run the following to help secure the installation of MySQL:

sudo mysql_secure_installation

Database and User

We are then ready to create a new database, a user, and setup the user's privileges on that database:

create database myapp charset utf8mb4;

create user myuser@'localhost' identified by 'secret';

grant all privileges on myapp.* to myuser@'localhost';

flush privileges;

This creates a new database with the utf8mb4 character set. Then it creates a new user who can only connect over localhost, gives it a password of secret and sets those user's privileges to be able to use and change database myapp.

Finally we flush privileges to tell MySQL to re-cache its record of users and permissions in-memory.

Configure Laravel

All we need to do for Laravel is to edit the .env file:


We can test that these work by setting up Laravel's auth scaffolding:

php artisan make:auth
php artisan migrate

If the migration works, then we're all set. We can test registering a user and ensure there's a new user in our database.

localhost vs, and users

The last part of the video shows the difference between logging in over localhost and - a Unix socket vs a TCP socket.

We then change MySQL's bind-address to the local private network and see we can still log in over host localhost but not, since MySQL is no longer listening on the loopback interface network (
