基础介绍

它是什么？

RoadRunner 是用 Golang 编写的 PHP 应用程序的基础架构级框架。它以worker的形式运行您的应用程序。

高朗

在 Golang 端 RoadRunner 在goroutine上运行你的 PHP 应用程序， 并在多个 worker 之间平衡传入的有效负载。

可以从 HTTP 请求、AWS Lambda、队列或任何其他方式接收数据。

PHP

RoadRunner 在传入请求之间保持 PHP worker 处于活动状态。这意味着您可以完全消除引导加载时间（例如框架初始化）并大大加快繁重的应用程序。

由于 worker 位于常驻内存中，因此所有打开的资源将保持打开以供下一个请求使用。使用 Goridge RPC，您可以快速将一些复杂的计算卸载到应用服务器。例如，安排后台 PHP job。

关于RoadRunner

     

RoadRunner 是一个开源（MIT 许可）、高性能 PHP 应用程序服务器、负载均衡器和进程管理器。它支持作为服务运行，能够在每个项目的基础上扩展其功能。RoadRunner 包括 PSR-7 兼容的 HTTP 服务器。

特征：

• 生产就绪
• 符合 PCI DSS
• PSR-7 HTTP 服务器（文件上传、错误处理、静态文件、热重载、中间件、事件监听器）
• HTTPS 和 HTTP/2 支持（包括 HTTP/2 Push、H2C）
• 一个完全可定制的服务器，FastCGI 支持
• 灵活的环境配置
• 无外部 PHP 依赖（需要 64 位版本），嵌入式（基于Goridge）
• 负载平衡器、流程管理器和任务管道
• 集成指标（Prometheus）
• Temporal.io 的工作流引擎
• 在 TCP、UNIX 套接字和标准管道上工作
• 自动更换Worker 和安全的 PHP 进程销毁
• Worker 创建/分配/销毁超时
• 每个Worker 的最大工作量
• Worker 生命周期管理（控制器）
  • maxMemory（优雅停止）
  • TTL（优雅停止）
  • idleTTL（优雅停止）
  • execTTL (brute, max_execution_time)
• 有效负载上下文和正文
• 协议、工作者和作业级错误管理（包括 PHP 错误）
• 开发模式
• 与 Symfony、Laravel、Slim、CakePHP、Zend Expressive 的集成
• Spiral应用服务器
• 文件更改时自动重新加载
• 适用于 Windows（Windows 10 支持的 Unix 套接字 (AF_UNIX)）

执照：

麻省理工学院许可证 (MIT)。请参阅LICENSE以获取更多信息。通过 SpiralScout。

安装

获取最新 RoadRunner 版本的最简单方法是使用预构建的发行版二进制文件之一，这些文件可用于 OSX、Linux、FreeBSD 和 Windows。使用这些二进制文件的说明位于 GitHub版本页面 上。

通过 Composer 安装

您还可以使用 Composer 软件包附带的命令自动安装 RoadRunner，运行：

$ composer require spiral/roadrunner
$ ./vendor/bin/rr get

服务器二进制文件将在您的项目的根目录中可用。

PHP 的扩展php-curl并且php-zip需要自动下载 RoadRunner。

建造 RoadRunner

RoadRunner 可以在 Linux、OSX、Windows 和其他 64 位环境上编译，因为唯一的要求是Go 1.13+。

要获取所有需要的依赖项：

$ go mod download

构建：

$ make

去测试：

$ make test

配置

每个 RoadRunner 插件都需要正确配置。默认情况下，此类配置会合并到一个文件中，该文件必须位于项目的根目录中。每个服务配置都位于指定部分下。配置文件必须命名为.rr.{format}格式所在的位置yml，json以及其他支持的spf13/viper.

最低配置

您不需要启用每个插件来使 RoadRunner 工作。给定的配置只启用必要的插件来使 HTTP 端点工作：

rpc:
  listen: tcp://127.0.0.1:6001

server:
  command: "php tests/psr-worker-bench.php"

http:
  address: "0.0.0.0:8080"
  pool:
    num_workers: 4   

控制台标志

您可以使用-o标志覆盖任何配置值：

rr serve -o http.address=:80 -o http.workers.pool.numWorkers=1

这些值将与.rr文件合并。

环境变量

RoadRunner 将使用对环境变量的引用替换一些配置选项：

http:
  pool.num_workers: ${NUM_WORKERS}
