简介

Laravel 辛烷值 通过高性能应用服务器（如 FrankenPHP, Open Swoole, Swoole, 和 RoadRunner）来运行您的应用，从而大幅提升性能。Octane 会在启动时一次性加载您的应用并常驻内存，随后以超高速处理请求。

安装指南

可以通过 Composer 包管理器安装 Octane：

composer require laravel/octane

安装完成后，可以执行 octane:install Artisan 命令，该命令会在您的应用中安装 Octane 的配置文件：

php artisan octane:install

服务器环境要求

[!警告]
Laravel 辛烷值 需要 PHP 8.1+.

FrankenPHP

FrankenPHP 是一款基于 Go 语言开发的 PHP 应用服务器，支持早期提示（early hints）、Brotli 和 Zstandard 压缩等现代 Web 特性。当您安装 Octane 并选择 FrankenPHP 作为服务器时，Octane 将自动为您下载并安装 FrankenPHP 二进制文件。

通过 Laravel Sail 使用 FrankenPHP

如果您计划使用 Laravel Sail 进行开发，请运行以下命令安装 Octane 和 FrankenPHP：

./vendor/bin/sail up

./vendor/bin/sail composer require laravel/octane

接着使用 octane:install Artisan 命令安装 FrankenPHP 二进制文件：

./vendor/bin/sail artisan octane:install --server=frankenphp

最后，在您应用的 docker-compose.yml 文件中，为 laravel.test 服务添加 SUPERVISOR_PHP_COMMAND 环境变量。该变量将指定 Sail 使用 Octane 而非 PHP 开发服务器来运行应用：

services:
  laravel.test:
    environment:
      SUPERVISOR_PHP_COMMAND: "/usr/bin/php -d variables_order=EGPCS /var/www/html/artisan octane:start --server=frankenphp --host=0.0.0.0 --admin-port=2019 --port='${APP_PORT:-80}'"
      XDG_CONFIG_HOME:  /var/www/html/config
      XDG_DATA_HOME:  /var/www/html/data

如需启用 HTTPS、HTTP/2 和 HTTP/3，请改用以下配置：

services:
  laravel.test:
    ports:
        - '${APP_PORT:-80}:80'
        - '${VITE_PORT:-5173}:${VITE_PORT:-5173}'
        - '443:443'
        - '443:443/udp'
    environment:
      SUPERVISOR_PHP_COMMAND: "/usr/bin/php -d variables_order=EGPCS /var/www/html/artisan octane:start --host=localhost --port=443 --admin-port=2019 --https"
      XDG_CONFIG_HOME:  /var/www/html/config
      XDG_DATA_HOME:  /var/www/html/data

建议通过 https://localhost 访问 FrankenPHP Sail 应用。使用 https://127.0.0.1 需要额外配置，且不推荐使用该方式。

通过 Docker 使用 FrankenPHP

FrankenPHP 官方 Docker 镜像能提供更优性能，并支持静态安装版未包含的额外扩展。此外，这些镜像还支持在 Windows 等原生不支持 FrankenPHP 的平台上运行，既适用于本地开发也适用于生产环境。

以下 Dockerfile 可作为构建 FrankenPHP 驱动的 Laravel 应用容器的基础模板：

FROM dunglas/frankenphp

RUN install-php-extensions \
    pcntl
    # Add other PHP extensions here...

COPY . /app

ENTRYPOINT ["php", "artisan", "octane:frankenphp"]

开发阶段可使用以下 Docker Compose 配置文件运行应用：

# compose.yaml
services:
  frankenphp:
    build:
      context: .
    entrypoint: php artisan octane:frankenphp --workers=1 --max-requests=1
    ports:
      - "8000:8000"
    volumes:
      - .:/app

若向 php artisan octane:start 命令显式传递 --log-level 参数，Octane 将启用 FrankenPHP 原生日志记录器，默认生成结构化 JSON 日志（除非另行配置）。

更多 Docker 运行 FrankenPHP 的细节，请参阅官方 FrankenPHP 文档。

RoadRunner

RoadRunner 由 Go 语言编写的 RoadRunner 二进制驱动。首次启动基于 RoadRunner 的 Octane 服务时，Octane 将自动提示下载并安装 RoadRunner 二进制文件。

通过 Laravel Sail 使用 RoadRunner

若计划使用 Laravel Sail 开发，请执行以下命令安装 Octane 和 RoadRunner：

./vendor/bin/sail up

./vendor/bin/sail composer require laravel/octane spiral/roadrunner-cli spiral/roadrunner-http

Next, you should start a Sail shell and use the rr executable to retrieve the latest Linux based build of the RoadRunner binary:

./vendor/bin/sail shell

# Within the Sail shell...
./vendor/bin/rr get-binary

Then, add a SUPERVISOR_PHP_COMMAND environment variable to the laravel.test service definition in your application's docker-compose.yml file. This environment variable will contain the command that Sail will use to serve your application using Octane instead of the PHP development server:

services:
  laravel.test:
    environment:
      SUPERVISOR_PHP_COMMAND: "/usr/bin/php -d variables_order=EGPCS /var/www/html/artisan octane:start --server=roadrunner --host=0.0.0.0 --rpc-port=6001 --port='${APP_PORT:-80}'" # [tl! add]

Finally, ensure the rr binary is executable and build your Sail images:

chmod +x ./rr

./vendor/bin/sail build --no-cache

Swoole

If you plan to use the Swoole application server to serve your Laravel Octane application, you must install the Swoole PHP extension. Typically, this can be done via PECL:

pecl install swoole

Open Swoole

If you want to use the Open Swoole application server to serve your Laravel Octane application, you must install the Open Swoole PHP extension. Typically, this can be done via PECL:

pecl install openswoole

Using Laravel Octane with Open Swoole grants the same functionality provided by Swoole, such as concurrent tasks, ticks, and intervals.

Swoole via Laravel Sail

[!WARNING]
Before serving an Octane application via Sail, ensure you have the latest version of Laravel Sail and execute ./vendor/bin/sail build --no-cache within your application's root directory.

Alternatively, you may develop your Swoole based Octane application using Laravel Sail, the official Docker based development environment for Laravel. Laravel Sail includes the Swoole extension by default. However, you will still need to adjust the docker-compose.yml file used by Sail.

To get started, add a SUPERVISOR_PHP_COMMAND environment variable to the laravel.test service definition in your application's docker-compose.yml file. This environment variable will contain the command that Sail will use to serve your application using Octane instead of the PHP development server:

services:
  laravel.test:
    environment:
      SUPERVISOR_PHP_COMMAND: "/usr/bin/php -d variables_order=EGPCS /var/www/html/artisan octane:start --server=swoole --host=0.0.0.0 --port='${APP_PORT:-80}'" # [tl! add]

Finally, build your Sail images:

./vendor/bin/sail build --no-cache

Swoole Configuration

Swoole supports a few additional configuration options that you may add to your octane configuration file if necessary. Because they rarely need to be modified, these options are not included in the default configuration file:

'swoole' => [
    'options' => [
        'log_file' => storage_path('logs/swoole_http.log'),
        'package_max_length' => 10 * 1024 * 1024,
    ],
],

Serving Your Application

The Octane server can be started via the octane:start Artisan command. By default, this command will utilize the server specified by the server configuration option of your application's octane configuration file:

php artisan octane:start

By default, Octane will start the server on port 8000, so you may access your application in a web browser via http://localhost:8000.

Serving Your Application via HTTPS

By default, applications running via Octane generate links prefixed with http://. The OCTANE_HTTPS environment variable, used within your application's config/octane.php configuration file, can be set to true when serving your application via HTTPS. When this configuration value is set to true, Octane will instruct Laravel to prefix all generated links with https://:

'https' => env('OCTANE_HTTPS', false),

Serving Your Application via Nginx

[!NOTE]
If you aren't quite ready to manage your own server configuration or aren't comfortable configuring all of the various services needed to run a robust Laravel Octane application, check out Laravel Cloud, which offers fully-managed Laravel Octane support.

In production environments, you should serve your Octane application behind a traditional web server such as Nginx or Apache. Doing so will allow the web server to serve your static assets such as images and stylesheets, as well as manage your SSL certificate termination.

In the Nginx configuration example below, Nginx will serve the site's static assets and proxy requests to the Octane server that is running on port 8000:

map $http_upgrade $connection_upgrade {
    default upgrade;
    ''      close;
}

server {
    listen 80;
    listen [::]:80;
    server_name domain.com;
    server_tokens off;
    root /home/forge/domain.com/public;

    index index.php;

    charset utf-8;

    location /index.php {
        try_files /not_exists @octane;
    }

    location / {
        try_files $uri $uri/ @octane;
    }

    location = /favicon.ico { access_log off; log_not_found off; }
    location = /robots.txt  { access_log off; log_not_found off; }

    access_log off;
    error_log  /var/log/nginx/domain.com-error.log error;

    error_page 404 /index.php;

    location @octane {
        set $suffix "";

        if ($uri = /index.php) {
            set $suffix ?$query_string;
        }

        proxy_http_version 1.1;
        proxy_set_header Host $http_host;
        proxy_set_header Scheme $scheme;
        proxy_set_header SERVER_PORT $server_port;
        proxy_set_header REMOTE_ADDR $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection $connection_upgrade;

        proxy_pass http://127.0.0.1:8000$suffix;
    }
}

Watching for File Changes

Since your application is loaded in memory once when the Octane server starts, any changes to your application's files will not be reflected when you refresh your browser. For example, route definitions added to your routes/web.php file will not be reflected until the server is restarted. For convenience, you may use the --watch flag to instruct Octane to automatically restart the server on any file changes within your application:

php artisan octane:start --watch

Before using this feature, you should ensure that Node is installed within your local development environment. In addition, you should install the Chokidar file-watching library within your project:

npm install --save-dev chokidar

You may configure the directories and files that should be watched using the watch configuration option within your application's config/octane.php configuration file.

Specifying the Worker Count

By default, Octane will start an application request worker for each CPU core provided by your machine. These workers will then be used to serve incoming HTTP requests as they enter your application. You may manually specify how many workers you would like to start using the --workers option when invoking the octane:start command:

php artisan octane:start --workers=4

If you are using the Swoole application server, you may also specify how many "task workers" you wish to start:

php artisan octane:start --workers=4 --task-workers=6

Specifying the Max Request Count

To help prevent stray memory leaks, Octane gracefully restarts any worker once it has handled 500 requests. To adjust this number, you may use the --max-requests option:

php artisan octane:start --max-requests=250

Reloading the Workers

You may gracefully restart the Octane server's application workers using the octane:reload command. Typically, this should be done after deployment so that your newly deployed code is loaded into memory and is used to serve to subsequent requests:

php artisan octane:reload

Stopping the Server

You may stop the Octane server using the octane:stop Artisan command:

php artisan octane:stop

Checking the Server Status

You may check the current status of the Octane server using the octane:status Artisan command:

php artisan octane:status

Dependency Injection and Octane

Since Octane boots your application once and keeps it in memory while serving requests, there are a few caveats you should consider while building your application. For example, the register and boot methods of your application's service providers will only be executed once when the request worker initially boots. On subsequent requests, the same application instance will be reused.

In light of this, you should take special care when injecting the application service container or request into any object's constructor. By doing so, that object may have a stale version of the container or request on subsequent requests.

Octane will automatically handle resetting any first-party framework state between requests. However, Octane does not always know how to reset the global state created by your application. Therefore, you should be aware of how to build your application in a way that is Octane friendly. Below, we will discuss the most common situations that may cause problems while using Octane.

Container Injection

In general, you should avoid injecting the application service container or HTTP request instance into the constructors of other objects. For example, the following binding injects the entire application service container into an object that is bound as a singleton:

use App\Service;
use Illuminate\Contracts\Foundation\Application;

/**
 * Register any application services.
 */
public function register(): void
{
    $this->app->singleton(Service::class, function (Application $app) {
        return new Service($app);
    });
}

In this example, if the Service instance is resolved during the application boot process, the container will be injected into the service and that same container will be held by the Service instance on subsequent requests. This may not be a problem for your particular application; however, it can lead to the container unexpectedly missing bindings that were added later in the boot cycle or by a subsequent request.

As a work-around, you could either stop registering the binding as a singleton, or you could inject a container resolver closure into the service that always resolves the current container instance:

use App\Service;
use Illuminate\Container\Container;
use Illuminate\Contracts\Foundation\Application;

$this->app->bind(Service::class, function (Application $app) {
    return new Service($app);
});

$this->app->singleton(Service::class, function () {
    return new Service(fn () => Container::getInstance());
});

The global app helper and the Container::getInstance() method will always return the latest version of the application container.

Request Injection

In general, you should avoid injecting the application service container or HTTP request instance into the constructors of other objects. For example, the following binding injects the entire request instance into an object that is bound as a singleton:

use App\Service;
use Illuminate\Contracts\Foundation\Application;

/**
 * Register any application services.
 */
public function register(): void
{
    $this->app->singleton(Service::class, function (Application $app) {
        return new Service($app['request']);
    });
}

In this example, if the Service instance is resolved during the application boot process, the HTTP request will be injected into the service and that same request will be held by the Service instance on subsequent requests. Therefore, all headers, input, and query string data will be incorrect, as well as all other request data.

As a work-around, you could either stop registering the binding as a singleton, or you could inject a request resolver closure into the service that always resolves the current request instance. Or, the most recommended approach is simply to pass the specific request information your object needs to one of the object's methods at runtime:

use App\Service;
use Illuminate\Contracts\Foundation\Application;

$this->app->bind(Service::class, function (Application $app) {
    return new Service($app['request']);
});

$this->app->singleton(Service::class, function (Application $app) {
    return new Service(fn () => $app['request']);
});

// Or...

$service->method($request->input('name'));

The global request helper will always return the request the application is currently handling and is therefore safe to use within your application.

[!WARNING]
It is acceptable to type-hint the Illuminate\Http\Request instance on your controller methods and route closures.

Configuration Repository Injection

In general, you should avoid injecting the configuration repository instance into the constructors of other objects. For example, the following binding injects the configuration repository into an object that is bound as a singleton:

use App\Service;
use Illuminate\Contracts\Foundation\Application;

/**
 * Register any application services.
 */
public function register(): void
{
    $this->app->singleton(Service::class, function (Application $app) {
        return new Service($app->make('config'));
    });
}

In this example, if the configuration values change between requests, that service will not have access to the new values because it's depending on the original repository instance.

As a work-around, you could either stop registering the binding as a singleton, or you could inject a configuration repository resolver closure to the class:

use App\Service;
use Illuminate\Container\Container;
use Illuminate\Contracts\Foundation\Application;

$this->app->bind(Service::class, function (Application $app) {
    return new Service($app->make('config'));
});

$this->app->singleton(Service::class, function () {
    return new Service(fn () => Container::getInstance()->make('config'));
});

The global config will always return the latest version of the configuration repository and is therefore safe to use within your application.

Managing Memory Leaks

Remember, Octane keeps your application in memory between requests; therefore, adding data to a statically maintained array will result in a memory leak. For example, the following controller has a memory leak since each request to the application will continue to add data to the static $data array:

use App\Service;
use Illuminate\Http\Request;
use Illuminate\Support\Str;

/**
 * Handle an incoming request.
 */
public function index(Request $request): array
{
    Service::$data[] = Str::random(10);

    return [
        // ...
    ];
}

While building your application, you should take special care to avoid creating these types of memory leaks. It is recommended that you monitor your application's memory usage during local development to ensure you are not introducing new memory leaks into your application.

Concurrent Tasks

[!WARNING]
This feature requires Swoole.

When using Swoole, you may execute operations concurrently via light-weight background tasks. You may accomplish this using Octane's concurrently method. You may combine this method with PHP array destructuring to retrieve the results of each operation:

use App\Models\User;
use App\Models\Server;
use Laravel\Octane\Facades\Octane;

[$users, $servers] = Octane::concurrently([
    fn () => User::all(),
    fn () => Server::all(),
]);

Concurrent tasks processed by Octane utilize Swoole's "task workers", and execute within an entirely different process than the incoming request. The amount of workers available to process concurrent tasks is determined by the --task-workers directive on the octane:start command:

php artisan octane:start --workers=4 --task-workers=6

When invoking the concurrently method, you should not provide more than 1024 tasks due to limitations imposed by Swoole's task system.

Ticks and Intervals

[!WARNING]
This feature requires Swoole.

When using Swoole, you may register "tick" operations that will be executed every specified number of seconds. You may register "tick" callbacks via the tick method. The first argument provided to the tick method should be a string that represents the name of the ticker. The second argument should be a callable that will be invoked at the specified interval.

In this example, we will register a closure to be invoked every 10 seconds. Typically, the tick method should be called within the boot method of one of your application's service providers:

Octane::tick('simple-ticker', fn () => ray('Ticking...'))
    ->seconds(10);

Using the immediate method, you may instruct Octane to immediately invoke the tick callback when the Octane server initially boots, and every N seconds thereafter:

Octane::tick('simple-ticker', fn () => ray('Ticking...'))
    ->seconds(10)
    ->immediate();

The Octane Cache

[!WARNING]
This feature requires Swoole.

When using Swoole, you may leverage the Octane cache driver, which provides read and write speeds of up to 2 million operations per second. Therefore, this cache driver is an excellent choice for applications that need extreme read / write speeds from their caching layer.

This cache driver is powered by Swoole tables. All data stored in the cache is available to all workers on the server. However, the cached data will be flushed when the server is restarted:

Cache::store('octane')->put('framework', 'Laravel', 30);

[!NOTE]
The maximum number of entries allowed in the Octane cache may be defined in your application's octane configuration file.

Cache Intervals

In addition to the typical methods provided by Laravel's cache system, the Octane cache driver features interval based caches. These caches are automatically refreshed at the specified interval and should be registered within the boot method of one of your application's service providers. For example, the following cache will be refreshed every five seconds:

use Illuminate\Support\Str;

Cache::store('octane')->interval('random', function () {
    return Str::random(10);
}, seconds: 5);

Tables

[!WARNING]
This feature requires Swoole.

When using Swoole, you may define and interact with your own arbitrary Swoole tables. Swoole tables provide extreme performance throughput and the data in these tables can be accessed by all workers on the server. However, the data within them will be lost when the server is restarted.

Tables should be defined within the tables configuration array of your application's octane configuration file. An example table that allows a maximum of 1000 rows is already configured for you. The maximum size of string columns may be configured by specifying the column size after the column type as seen below:

'tables' => [
    'example:1000' => [
        'name' => 'string:1000',
        'votes' => 'int',
    ],
],

To access a table, you may use the Octane::table method:

use Laravel\Octane\Facades\Octane;

Octane::table('example')->set('uuid', [
    'name' => 'Nuno Maduro',
    'votes' => 1000,
]);

return Octane::table('example')->get('uuid');

[!WARNING]
The column types supported by Swoole tables are: string, int, and float.
