nginx基本概念

nginx [engine x] is an HTTP and reverse proxy server, a mail proxy server, and a generic TCP/UDP proxy server, originally written by Igor Sysoev. For a long time, it has been running on many heavily loaded Russian sites including Yandex, Mail.Ru, VK, and Rambler. According to Netcraft, nginx served or proxied 25.89% busiest sites in December 2018. Here are some of the success stories: Dropbox, Netflix, Wordpress.com, FastMail.FM.

Nginx是一个Http服务器、反向代理服务器、邮件代理服务器、通用TCP/UDP代理服务器，目前已经占据25%的市场份额。

nginx has one master process and several worker processes. The main purpose of the master process is to read and evaluate configuration, and maintain worker processes. Worker processes do actual processing of requests. nginx employs event-based model and OS-dependent mechanisms to efficiently distribute requests among worker processes. The number of worker processes is defined in the configuration file and may be fixed for a given configuration or automatically adjusted to the number of available CPU cores.

nginx有一个master进程和多个worker进程，maste进程负责读取配置和管理worker进程，worker进程负责实际的请求处理；nginx使用事件模型和操作系统特有的机制来高效在worker进程中转发请求；
