Installing Elasticsearch
To install Elasticsearch, add the elasticsearch option to your Homestead.yaml file and specify a supported version, which may be a major version or an exact version number (major.minor.patch). The default installation will create a cluster named ‘homestead’. You should never give Elasticsearch more than half of the operating system’s memory, so make sure your Homestead machine has at least twice the Elasticsearch allocation:

Laravel Per Project Installation

Instead of installing Homestead globally and sharing the same Homestead box across all of your projects, you may instead configure a Homestead instance for each project you manage. Installing Homestead per project may be beneficial if you wish to ship a Vagrantfile with your project, allowing others working on the project to vagrant up.

To install Homestead directly into your project, require it using Composer:

Once Homestead has been installed, use the make command to generate the Vagrantfile and Homestead.yaml file in your project root. The make command will automatically configure the sites and folders directives in the Homestead.yaml file.

Mac / Linux:

php vendor/bin/homestead make
Windows:

vendor\\bin\\homestead make
Next, run the vagrant up command in your terminal and access your project at http://homestead.test in your browser. Remember, you will still need to add an /etc/hosts file entry for homestead.test or the domain of your choice.
なるほど、vagrant構築手順か。

Installing MariaDB
If you prefer to use MariaDB instead of MySQL, you may add the mariadb option to your Homestead.yaml file. This option will remove MySQL and install MariaDB. MariaDB serves as a drop-in replacement for MySQL so you should still use the mysql database driver in your application’s database configuration:
MariaDBも使えるとのこと。使ったことないぞ。

box: laravel/homestead
ip: “192.168.10.10”

laravel Configuring Homestead

Setting Your Provider
The provider key in your Homestead.yaml file indicates which Vagrant provider should be used: virtualbox, vmware_fusion, vmware_workstation, parallels or hyperv. You may set this to the provider you prefer:

The folders property of the Homestead.yaml file lists all of the folders you wish to share with your Homestead environment. As files within these folders are changed, they will be kept in sync between your local machine and the Homestead environment. You may configure as many shared folders as necessary:
vagrantの設定です。

folders:
– map: ~/code/project1
to: /home/vagrant/code/project1

– map: ~/code/project2
to: /home/vagrant/code/project2

You may also pass any options supported by Vagrant’s Synced Folders by listing them under the options key:

folders:
– map: ~/code
to: /home/vagrant/code
type: “rsync”
options:
rsync__args: [“–verbose”, “–archive”, “–delete”, “-zz”]
rsync__exclude: [“node_modules”]
このへんもそうですね。

Configuring Nginx Sites
Not familiar with Nginx? No problem. The sites property allows you to easily map a “domain” to a folder on your Homestead environment. A sample site configuration is included in the Homestead.yaml file. Again, you may add as many sites to your Homestead environment as necessary. Homestead can serve as a convenient, virtualized environment for every Laravel project you are working on:

If you change the sites property after provisioning the Homestead box, you should re-run vagrant reload –provision to update the Nginx configuration on the virtual machine.

The Hosts File
You must add the “domains” for your Nginx sites to the hosts file on your machine. The hosts file will redirect requests for your Homestead sites into your Homestead machine. On Mac and Linux, this file is located at /etc/hosts. On Windows, it is located at C:\Windows\System32\drivers\etc\hosts. The lines you add to this file will look like the following:

192.168.10.10 homestead.test

etc/hosts の中身

127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6

なんじゃこりゃ。

Make sure the IP address listed is the one set in your Homestead.yaml file. Once you have added the domain to your hosts file and launched the Vagrant box you will be able to access the site via your web browser:

http://homestead.test

Launching The Vagrant Box
Once you have edited the Homestead.yaml to your liking, run the vagrant up command from your Homestead directory. Vagrant will boot the virtual machine and automatically configure your shared folders and Nginx sites.

To destroy the machine, you may use the vagrant destroy –force command.
あれ、homestead.yamlでvagrant upだっけ?boxファイルでなかった!?

Laravel Homestead

Homesteadの意味がわからん。

>公式サイトを読んだ限りでは、仮想マシン上に、ほんの数分で、OS、Nginx、PHP5.5、MySQL、Postgres、Redis、Memcached等のLaravelアプリケーションを開発するための環境を提供してくれるツールだと記述されています
なに、osも?ってことは、dockerっというより、isoまで!?すげーな、最近のフレームワークは。

Laravel strives to make the entire PHP development experience delightful, including your local development environment. Vagrant provides a simple, elegant way to manage and provision Virtual Machines.
あ、vagrantって書いてます。

Laravel Homestead is an official, pre-packaged Vagrant box that provides you a wonderful development environment without requiring you to install PHP, a web server, and any other server software on your local machine. No more worrying about messing up your operating system! Vagrant boxes are completely disposable. If something goes wrong, you can destroy and re-create the box in minutes!
あ、なんだ、vagrant boxのことじゃん。box引っ張て来て、vagrant initするだけです。しかし、homesteadという名称がわかりにくい。

Homestead runs on any Windows, Mac, or Linux system, and includes the Nginx web server, PHP 7.3, PHP 7.2, PHP 7.1, PHP 7.0, PHP 5.6, MySQL, PostgreSQL, Redis, Memcached, Node, and all of the other goodies you need to develop amazing Laravel applications.

setup
Before launching your Homestead environment, you must install VirtualBox 5.2, VMWare, Parallels or Hyper-V as well as Vagrant. All of these software packages provide easy-to-use visual installers for all popular operating systems.
To use the VMware provider, you will need to purchase both VMware Fusion / Workstation and the VMware Vagrant plug-in. Though it is not free, VMware can provide faster shared folder performance out of the box.
To use the Parallels provider, you will need to install Parallels Vagrant plug-in. It is free of charge.
Because of Vagrant limitations, The Hyper-V provider ignores all networking settings.
vagrantのプラグインか。

Once VirtualBox / VMware and Vagrant have been installed, you should add the laravel/homestead box to your Vagrant installation using the following command in your terminal. It will take a few minutes to download the box, depending on your Internet connection speed:

You may install Homestead by cloning the repository. Consider cloning the repository into a Homestead folder within your “home” directory, as the Homestead box will serve as the host to all of your Laravel projects:

homestead、ありました。
https://github.com/laravel/homestead

Once you have cloned the Homestead repository, run the bash init.sh command from the Homestead directory to create the Homestead.yaml configuration file. The Homestead.yaml file will be placed in the Homestead directory:

laravel app directory

The majority of your application is housed in the app directory. By default, this directory is namespaced under App and is autoloaded by Composer using the PSR-4 autoloading standard.

ん?PSR-4 autoloading standard?
classのautoloadingが書いてある。app配下はconsole, exceptions, http, providers, user.phpです。
https://www.php-fig.org/psr/psr-4/

The app directory contains a variety of additional directories such as Console, Http, and Providers. Think of the Console and Http directories as providing an API into the core of your application. The HTTP protocol and CLI are both mechanisms to interact with your application, but do not actually contain application logic. In other words, they are two ways of issuing commands to your application. The Console directory contains all of your Artisan commands, while the Http directory contains your controllers, middleware, and requests.
httpディレクトリか。確かにControllers, kernel, Middlewareのディレクトリがあります。

A variety of other directories will be generated inside the app directory as you use the make Artisan commands to generate classes. So, for example, the app/Jobs directory will not exist until you execute the make:job Artisan command to generate a job class.
appディレクトリはartisanコマンドで生成できる。

Introduction
The default Laravel application structure is intended to provide a great starting point for both large and small applications. Of course, you are free to organize your application however you like. Laravel imposes almost no restrictions on where any given class is located – as long as Composer can autoload the class.

Where Is The Models Directory?
When getting started with Laravel, many developers are confused by the lack of a models directory. However, the lack of such a directory is intentional. We find the word “models” ambiguous since it means many different things to many different people. Some developers refer to an application’s “model” as the totality of all of its business logic, while others refer to “models” as classes that interact with a relational database.

For this reason, we choose to place Eloquent models in the app directory by default, and allow the developer to place them somewhere else if they choose.

The Root Directory
The App Directory
The app directory, as you might expect, contains the core code of your application. We’ll explore this directory in more detail soon; however, almost all of the classes in your application will be in this directory.

The Bootstrap Directory
The bootstrap directory contains the app.php file which bootstraps the framework. This directory also houses a cache directory which contains framework generated files for performance optimization such as the route and services cache files.

The Config Directory
The config directory, as the name implies, contains all of your application’s configuration files. It’s a great idea to read through all of these files and familiarize yourself with all of the options available to you.

The Database Directory
The database directory contains your database migrations, model factories, and seeds. If you wish, you may also use this directory to hold an SQLite database.

The Public Directory
The public directory contains the index.php file, which is the entry point for all requests entering your application and configures autoloading. This directory also houses your assets such as images, JavaScript, and CSS.

The Resources Directory
The resources directory contains your views as well as your raw, un-compiled assets such as LESS, SASS, or JavaScript. This directory also houses all of your language files.

The Routes Directory
The routes directory contains all of the route definitions for your application. By default, several route files are included with Laravel: web.php, api.php, console.php and channels.php.

The web.php file contains routes that the RouteServiceProvider places in the web middleware group, which provides session state, CSRF protection, and cookie encryption. If your application does not offer a stateless, RESTful API, all of your routes will most likely be defined in the web.php file.

The api.php file contains routes that the RouteServiceProvider places in the api middleware group, which provides rate limiting. These routes are intended to be stateless, so requests entering the application through these routes are intended to be authenticated via tokens and will not have access to session state.

The console.php file is where you may define all of your Closure based console commands. Each Closure is bound to a command instance allowing a simple approach to interacting with each command’s IO methods. Even though this file does not define HTTP routes, it defines console based entry points (routes) into your application.

The channels.php file is where you may register all of the event broadcasting channels that your application supports.

The Storage Directory
The storage directory contains your compiled Blade templates, file based sessions, file caches, and other files generated by the framework. This directory is segregated into app, framework, and logs directories. The app directory may be used to store any files generated by your application. The framework directory is used to store framework generated files and caches. Finally, the logs directory contains your application’s log files.

The storage/app/public directory may be used to store user-generated files, such as profile avatars, that should be publicly accessible. You should create a symbolic link at public/storage which points to this directory. You may create the link using the php artisan storage:link command.

The Tests Directory
The tests directory contains your automated tests. An example PHPUnit is provided out of the box. Each test class should be suffixed with the word Test. You may run your tests using the phpunit or php vendor/bin/phpunit commands.

The Vendor Directory
The vendor directory contains your Composer dependencies.

The App Directory
The majority of your application is housed in the app directory. By default, this directory is namespaced under App and is autoloaded by Composer using the PSR-4 autoloading standard.

The app directory contains a variety of additional directories such as Console, Http, and Providers. Think of the Console and Http directories as providing an API into the core of your application. The HTTP protocol and CLI are both mechanisms to interact with your application, but do not actually contain application logic. In other words, they are two ways of issuing commands to your application. The Console directory contains all of your Artisan commands, while the Http directory contains your controllers, middleware, and requests.

A variety of other directories will be generated inside the app directory as you use the make Artisan commands to generate classes. So, for example, the app/Jobs directory will not exist until you execute the make:job Artisan command to generate a job class.

Tip!! Many of the classes in the app directory can be generated by Artisan via commands. To review the available commands, run the php artisan list make command in your terminal.

The Broadcasting Directory
The Broadcasting directory contains all of the broadcast channel classes for your application. These classes are generated using the make:channel command. This directory does not exist by default, but will be created for you when you create your first channel. To learn more about channels, check out the documentation on event broadcasting.
特に使用なしか。

The Console directory contains all of the custom Artisan commands for your application. These commands may be generated using the make:command command. This directory also houses your console kernel, which is where your custom Artisan commands are registered and your scheduled tasks are defined.
consoleはartisanのカスタムだそう。ほえ、色々考えて設計されてます。

The Exceptions Directory
The Exceptions directory contains your application’s exception handler and is also a good place to place any exceptions thrown by your application. If you would like to customize how your exceptions are logged or rendered, you should modify the Handler class in this directory.
デフォルトではHandler.phpが入っています。

The Http Directory
The Http directory contains your controllers, middleware, and form requests. Almost all of the logic to handle requests entering your application will be placed in this directory.
ロジックはほぼHttpディレクトリで制御している。主に編集するのはこの箇所。

The Jobs Directory
This directory does not exist by default, but will be created for you if you execute the make:job Artisan command. The Jobs directory houses the queueable jobs for your application. Jobs may be queued by your application or run synchronously within the current request lifecycle. Jobs that run synchronously during the current request are sometimes referred to as “commands” since they are an implementation of the command pattern.

The Listeners Directory
This directory does not exist by default, but will be created for you if you execute the event:generate or make:listener Artisan commands. The Listeners directory contains the classes that handle your events. Event listeners receive an event instance and perform logic in response to the event being fired. For example, a UserRegistered event might be handled by a SendWelcomeEmail listener
デフォルトでないディレクトリがたくさんあります。

The Mail Directory
This directory does not exist by default, but will be created for you if you execute the make:mail Artisan command. The Mail directory contains all of your classes that represent emails sent by your application. Mail objects allow you to encapsulate all of the logic of building an email in a single, simple class that may be sent using the Mail::send method.
やはりメール送信ができるようです。よくできているなー

The Notifications Directory
This directory does not exist by default, but will be created for you if you execute the make:notification Artisan command. The Notifications directory contains all of the “transactional” notifications that are sent by your application, such as simple notifications about events that happen within your application. Laravel’s notification features abstracts sending notifications over a variety of drivers such as email, Slack, SMS, or stored in a database.
AWSのSNSみたいなもんか。

The Policies Directory
This directory does not exist by default, but will be created for you if you execute the make:policy Artisan command. The Policies directory contains the authorization policy classes for your application. Policies are used to determine if a user can perform a given action against a resource. For more information, check out the authorization documentation.
authorizationは一番勉強しなければならない分野かも。

The Providers Directory
The Providers directory contains all of the service providers for your application. Service providers bootstrap your application by binding services in the service container, registering events, or performing any other tasks to prepare your application for incoming requests.

In a fresh Laravel application, this directory will already contain several providers. You are free to add your own providers to this directory as needed.

The Rules Directory
This directory does not exist by default, but will be created for you if you execute the make:rule Artisan command. The Rules directory contains the custom validation rule objects for your application. Rules are used to encapsulate complicated validation logic in a simple object. For more information, check out the validation documentation.
ルールも作れます。このあたりは、プログラマーの好みがあると思います。
