Ubuntu 22.04安装lnmp环境

一、lnmp简介

LNMP代表的就是：Linux系统下Nginx+MySQL(Mariadb)+PHP这种网站服务器架构。

Linux是一类Unix计算机操作系统的统称，是目前最流行的免费操作系统。代表版本有：debian、centos、ubuntu、fedora、gentoo等。

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。

MySQL是一个关系型数据库管理系统，由瑞典 MySQL AB 公司开发，属于 Oracle 旗下产品。MySQL是最流行的关系型数据库管理系统之一，在 WEB 应用方面，MySQL是最好的RDBMS (Relational Database Management System，关系数据库管理系统)应用软件之一。

MariaDB数据库管理系统是MySQL的一个分支，主要由开源社区在维护，采用GPL授权许可 MariaDB的目的是完全兼容MySQL，包括API和命令行，使之能轻松成为MySQL的代替品。在存储引擎方面，使用XtraDB来代替MySQL的InnoDB。 MariaDB由MySQL的创始人Michael Widenius主导开发，MariaDB名称来自Michael Widenius的女儿Maria的名字。

PHP（Hypertext Preprocessor）是一种广泛使用的开源服务器端脚本语言，尤其适用于Web开发。它最初由Rasmus Lerdorf于1994年创建，旨在简化网页开发过程。PHP可以嵌入到HTML中，并与多种数据库集成，最常用的是MySQL。其灵活性、易学性和强大的社区支持使得PHP成为开发动态网页和Web应用程序的首选语言之一。PHP代码在服务器上执行，生成的HTML发送到客户端，从而实现网页的动态交互。它广泛应用于各种Web开发项目，包括内容管理系统、电子商务平台和社交媒体网站。

这四种软件均为免费开源软件，组合到一起，成为一个免费、高效、扩展性强的网站服务系统。
