The Symfony Demo Application and MySQL 8

The Symfony Frame work is very popular with PHP developers and it has a very nice Demo Application to help novices learn the intricacies involved. But the demo does not use MySQL. So this blog entry is about re configuring the demo so it works with MySQL 8. And I am using Ubuntu 18.04 LTS to you may have to adjust the following commands to work with your operating system.

This is not difficult but there are some steps that are not exactly self evident that this blog will show you how to get the demo working.  


The first thing to do is to make sure you have PHP 7.2 or better installed including the php7.2-intl (sudo apt-get install php7.2-intl) package as well as the PDO connector. I will admit I have been using PHP since it appeared and this is the first time I have had to install this package.

And you will want Composer to do the behind the scenes lifting for you and Doctrine to map the relations in the PHP code to the database.  Please see my previous blog on getting Doctrine to work with MySQL 8 (Big hint for the TL;DR crowd, set your .env to DATABASE_URL=mysql://account:password@localhost:3306/databasename ).

You will want to create an account on the MySQL server for use with this demo and then make sure it will have the proper rights to use the new schema.

CREATE USER 'demouser'@'localhost' IDENTIFIED WITH mysql_native_password BY 'S3cr3t#'; 


GRANT ALL on 'databasename'.* to 'demouser'@'localhost'; 

The Demo

Now we can start work on the demo itself. 

The first thing to do in a terminal window is type composer create-project symfony/symfony-demo.  Composer will get the demo code ready for you.  Now cd cymfony-demo.   

Change the .env file (you may have to copy the .env-dist to .env and edit it) as noted above DATABASE_URL=mysql://demouser:S3c3t#@localhost:3306/databasename 

Now it is time to use Doctrine to build create the database, the schemas, and load the data.

$ php bin/console doctrine:database:create
$ php bin/console doctrine:schema:create
$ php bin/console doctrine:fixtures:load

Finally enter php bin/console server:run to start the demo. You will get a notice about the URL to use to get to the demo via a web browser. Use that URL in your web browser to get to the actual demo and below you can see that URL is

  1. Dave, thanks for publishing this article!

    We'd love to use a full-featured database like MySQL by default in the Symfony Demo application. However, our premise with that app is that it must work without forcing the user to configure anything, run any command or install anything (apart from PHP). That's why we use an embedded database like SQLite by default.

    Luckily, as you showed, switching to MySQL is simple, so developers needing that can do it themselves.
