  command [options] [arguments]

  install     Guides you through the installation process, to get Shlink up and running.
  list        List commands
  set-option  Allows you to set new values for any config option.
  update      Helps you import Shlink's config from an older version to a new one.

The most important ones are these:

• install: Used to set up Shlink from scratch.
• update: Used to update an existing Shlink instance. Will allow importing the config, skipping the options that already have a value.
• set-option: Allows to set the value for an individual option, in case you want to update it.

Customize options

Questions to ask the user

In order to retain backwards compatibility, it is possible to configure the installer to ask just a specific subset of questions.

Add a configuration file including a configuration like this:

<?php

declare(strict_types=1);

use Shlinkio\Shlink\Installer\Config\Option;

return [

    'installer' => [
        'enabled_options' => [
            Option\Database\DatabaseDriverConfigOption::class,
            Option\Database\DatabaseHostConfigOption::class,
            Option\BasePathConfigOption::class,
            Option\Redirect\Regular404RedirectConfigOption::class,
            Option\UrlShortener\ShortDomainHostConfigOption::class,
            Option\UrlShortener\ShortDomainSchemaConfigOption::class,
        ],
    ],

];

If installer.enabled_options is not provided at all, all the config options will be asked.

Commands to run after installation

After the user has been asked for all the config, the installer will run a set of scripts which will create/update the database, download assets, etc.

It is possible to overwrite those commands via configuration too, using a syntax like this:

<?php

declare(strict_types=1);

use Shlinkio\Shlink\Installer\Util\InstallationCommand;

return [

    'installer' => [
        'installation_commands' => [
            InstallationCommand::DB_CREATE_SCHEMA->value => [
                'command' => 'bin/shlink shlink:db:create',
            ],
            InstallationCommand::DB_MIGRATE->value => [
                'command' => 'bin/some-script some:command',
            ],
            InstallationCommand::ORM_PROXIES->value => [
                'command' => '-v', // Just print PHP version
            ],
        ],
    ],

];

This example shows all the currently available commands. They are run in the order they have been set here.

Important: Take into consideration that all the commands must be PHP scripts, since the installer will prefix all of them with the php binary.
