PHP – FastCGI Process

PHP FastCGI 进程管理器 (PHP-FPM) 是一个有效的替代传统基于 CGI 的方法，它用于处理 PHP 请求，特别是在高流量环境中。PHP-FPM 有一些重要的特性。这些特性如下所列 −

PHP FastCGI Process Manager (PHP-FPM) is an efficient alternative to traditional CGI-based methods for handling PHP requests, particularly in high-traffic environments. PHP-FPM has a number of important features. These features are as follows −

Reduced Memory Consumption

借助处理请求的工作进程池，与为每个请求产生一个新进程的传统 CGI 方法相比，PHP-FPM 大大降低了内存开销。

With the help of a pool of worker processes to handle requests PHP-FPM significantly reduces memory overhead compared to traditional CGI methods that spawn a new process for each request.

Improved Performance

PHP-FPM 的工作进程是持久的。它允许它们处理多个请求。它不需要重复创建和销毁进程。这提高了响应时间，并改善了高并发处理。

PHP-FPM’s worker processes are persistent. It allows them to handle multiple requests. It doesn’t need ti repeatedly create and destroy processes. This leads to faster response times and improved handling of high concurrency.

Enhanced Scalability

PHP-FPM 的工作进程池可以根据流量需求进行动态调整，从而使它能够有效地扩展以处理不同的工作负载。

PHP-FPM’s pool of worker processes can be dynamically adjusted based on traffic demands, allowing it to scale effectively to handle varying workloads.

Advanced Process Management

PHP-FPM 提供平滑的启动和关闭。它还对进程管理有细颗粒度控制，包括紧急重启和对工作进程的监控。

PHP-FPM offers graceful startup and shutdown. It also has granular control over process management, including, emergency restarts, and monitoring of worker processes.

Environment Isolation

PHP-FPM 能够为不同的应用程序或用户组创建不同的池，以便为每个环境提供更好的隔离和安全性。

PHP-FPM enables the creation of separate pools for different applications or user groups, so that better isolation and security can be provided for each environment.

Customizable Configuration

PHP-FPM 使用基于 php.ini 的配置选项。通过这些丰富的选项，可以微调其行为，以满足特定的应用程序要求。

PHP-FPM uses php.ini based configuration options. With these extensive options, fine-tuning of its behavior is possible to match specific application requirements.

Supports multiple PHP Versions

PHP-FPM 可同时管理多个 PHP 版本，从而可以在一台服务器上部署不同的 PHP 应用程序。

PHP-FPM can manage multiple PHP versions simultaneously, enabling the deployment of different PHP applications on a single server.

PHP-FPM 通常与 Nginx 或 Apache 等 Web 服务器一起使用。它用作处理 PHP 请求的后端处理器。由于其性能、可扩展性和可靠性，它已成为在生产环境中管理 PHP 应用程序的首选方法。

PHP-FPM is commonly used with web servers like Nginx or Apache. It acts as a backend processor for handling PHP requests. It has become the preferred method for managing PHP applications in production environments due to its performance, scalability, and reliability.
