How to start local server with symfony 5 or downgrade version to 4.4?

问题

I started a new project in new Symfony 5 and i can't open my local server.

On Symfony 4.4 the command PHP bin/console server:run is OK,

But with Symfony 5 the command appears not to be defined...

C:\Users\Chris\Code\api-test> php bin/console server:run
Command "server:run" is not defined.
Do you want to run "server:dump" instead?  (yes/no) [no]:

So how to downgrade or start the local server?

回答1:

For running a local web server you can now use Symfony Client, or simply 'Symfony'.

1. Download the binary and install it globally.

2. Open a terminal and run once: symfony server:ca:install. This will install a local SSL certificate authority that allows you to run the local webserver on https://.

3. Inside the terminal, move into your project directory and run symfony serve. A local webserver will start; by default on https://localhost:8000/.

If you wish to run the webserver on another port you can use symfony serve --port=8080 (in this case port 8080). For the most useful commands Symfony Client has to offer, simply run symfony. For all commands run symfony help.

The Web Server Bundle is not included with Symfony 5.

But you can simply require it and install it separately.

E.g.

composer require symfony/web-server-bundle 4.4

It is important that you specify the version (4.4), because otherwise it will attempt to install version 5 (which does not exist, and it will fail).

After that you'll be able to run bin/console server:run as you used to do.

If not, if you are already using the symfony executable, you can instead use symfony server:start, as shown here.

You need to install symfony by running theses commands: cd my-project composer require symfony/web-server-bundle --dev And run the server php bin/console server:run
