nginx介绍
- Nginx (engine x) 是一个高性能的HTTP和反向代理web服务器，同时也提供了IMAP/POP3/SMTP服务。Nginx是由伊戈尔·赛索耶夫为俄罗斯访问量第二的Rambler.ru站点（俄文：Рамблер）开发的，公开版本1.19.6发布于2020年12月15日。 [12]
- 其将源代码以类BSD许可证的形式发布，因它的稳定性、丰富的功能集、简单的配置文件和低系统资源的消耗而闻名。2022年01月25日，nginx 1.21.6发布。 [13]
- Nginx是一款轻量级的Web 服务器/反向代理服务器及电子邮件（IMAP/POP3）代理服务器，在BSD-like 协议下发行。其特点是占有内存少，并发能力强，事实上nginx的并发能力在同类型的网页服务器中表现较好。
