Build your own OAuth2 Server with Symfony and PHP

This is the sample app accompanying my blog post at https://davegebler.com/post/php/build-oauth2-server-php-symfony

Setup instructions - Docker

1. Clone this repo
2. Ensure you have Docker Engine >= 17.05 installed. https://docs.docker.com/get-docker/
3. Run docker compose up -d
4. Run the included setup.sh script to install dependencies and create the database.
5. Visit http://localhost:8080 in your browser and click the single sign-on link to see the app in action.
   1. The username is me@davegebler.com and the password is password

Setup instructions - manual

1. Ensure you have PHP >= 8.1 installed, as well as the Symfony CLI, Composer and OpenSSL.
2. Clone the repo
3. Run composer install in both the main project dir and the client dir
4. In the project dir, ensure the directory var is crated and is writable.
5. Ensure the directory var/keys is created.
6. Generate your keys using OpenSSL from inside the var/keys directory:
   1. openssl genrsa -out private.key 2048
   2. openssl rsa -in private.key -pubout -out public.key
7. If necessary, make the bin/console script executable: chmod +x bin/console
8. Run bin/console doctrine:database:create to create the SQLite database.
9. Run bin/console doctrine:schema:create to create the database tables.
10. Run bin/console app:bootstrap to bootstrap the database with the demo data.
    1. Run bin/console app:bootstrap --help for more options.
    2. Otherwise the default user is me@davegebler.com with password password.
11. Run symfony server:start -d to start the server in the background on port 8000.
12. From the client directory, run php -S localhost:8080 app.php to start the client on port 8080.
13. You may need to edit the client/app.php file to change the URI variables to match the URL and port of your local server.
    1. For example, your Symfony server may use https://localhost:8000 instead of http://localhost:8000.
14. Visit http://localhost:8080 in your browser and click the single sign-on link to see the app in action.
