Prerequisites

We’re using PHP in the stable version 8:

[isabell@stardust ~]$ uberspace tools version show php
Using 'PHP' version: '8.0'
[isabell@stardust ~]$

Your symfony URL needs to be setup:

[isabell@stardust ~]$ uberspace web domain list
isabell.uber.space
[isabell@stardust ~]$

Installation

Install symfony cli

[isabell@stardust ~]$ wget https://get.symfony.com/cli/installer -O - | bash -s -- --install-dir $HOME/bin

Configure Git

Symfony creates a new project with a new GIT-Repository, so please make sure that you have configured your GIT Name.

Check you name and email for Git

[isabell@stardust isabell]$ git config --global user.email
[isabell@stardust isabell]$ git config --global user.name

Set your name and email for Git

[isabell@stardust isabell]$ git config --global user.email "you@example.com"
[isabell@stardust isabell]$ git config --global user.name "Your Name"

Create symfony project

[isabell@stardust ~]$ cd /var/www/virtual/$USER/
[isabell@stardust isabell]$ symfony new my_project
* Creating a new Symfony project with Composer
  (running /usr/local/bin/composer create-project symfony/skeleton /var/www/virtual/isabell/my_project  --no-interaction)
* Setting up the project under Git version control
  (running git init /var/www/virtual/isabell/my_project)
[OK] Your project is now ready in /var/www/virtual/isabell/my_project

Adding Rewrite Rules

[isabell@stardust isabell]$ cd /var/www/virtual/$USER/my_project
[isabell@stardust isabell]$ composer require symfony/apache-pack
-  WARNING  symfony/apache-pack (>=1.0): From github.com/symfony/recipes-contrib:master

Nothing to unpack

Configuration

Configure the web server

We connect our symfony public folder to our web server

[isabell@stardust ~]$ cd /var/www/virtual/$USER
[isabell@stardust ~]$ rm -f html/nocontent.html; rmdir html
[isabell@stardust ~]$ ln -s /var/www/virtual/$USER/my_project/public /var/www/virtual/$USER/html

Finishing installation

Point your browser to URL and build up your project.

Best practices

Security

Per default you are in DEV-mode, so please restrict public-access or switch to PROD-mode. Modify /var/www/virtual/$USER/my_project/.env and replace APP_ENV=dev with APP_ENV=prod

To enable debugging only for your developer ip, use the SetEnvIf in the /var/www/virtual/$USER/my_project/public/.htaccess For example we are using a subnet 123.456.789.0/24 for debugging:

SetEnvIf Remote_Addr "^123.456.789.*" APP_ENV dev

Logging

We can use Monolog to log all of our messages

[isabell@stardust ~]$ cd /var/www/virtual/$USER/my_project
[isabell@stardust my_project]$ composer require symfony/monolog-bundle

Now you can configure your logging as needed: Symfony Logging

Debug

Install the debug-package within our dev-environment

[isabell@stardust ~]$ cd /var/www/virtual/$USER/my_project
[isabell@stardust my_project]$ composer require --dev debug-pack

To see the Debugger we have to disable the uberspace-error-page

[isabell@stardust ~]$ uberspace web errorpage 500 disable
Error page for HTTP 500 is disabled.

Updates

symfony check:security

Note

Check the update Releases regularly to stay informed about the newest version.

Check whether your project’s dependencies contain any known security vulnerability:

[isabell@stardust ~]$ cd /var/www/virtual/isabell/my_project
[isabell@stardust my_project]$ symfony check:security
Symfony Security Check Report
=============================

No packages have known vulnerabilities.

Note that this checker can only detect vulnerabilities that are referenced in the security advisories database.
Execute this command regularly to check the newly discovered vulnerabilities.

Tested with Symfony 5.2.6, Uberspace 7.10.0
