LNMP简介
LNMP
一、LNMP是什么
LNMP是指一组通常一起使用来运行动态网站或者服务器的自由软件名称首字母缩写。L指Linux，N指Nginx，M一般指MySQL，也可以指MariaDB，P一般指PHP，也可以指Perl或Python。
二、LNMP介绍
LNMP代表的就是：Linux系统下Nginx+MySQL+PHP这种网站服务器架构。
（1）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。
（2）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。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
（3）MySQL是一种开放源代码的关系型数据库管理系统（RDBMS），使用最常用的数据库管理语言--结构化查询语言（SQL）进行数据库管理。MySQL不仅是开放源代码的，也因为其速度、可靠性和适应性而备受关注。大多数人都认为在不需要事务化处理的情况下，MySQL是管理内容最好的选择。
（4）PHP即“超文本预处理器”，是一种通用开源脚本语言。PHP是在服务器端执行的脚本语言，与C语言类似，是常用的网站编程语言。因为PHP的开源性、免费性、快捷性等特点使其成为目前最流行的编程语言。
三、优点
（1）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。
（2）Nginx使用更少的资源，支持更多的并发连接，体现更高的效率。
（3）Nginx 既可以在内部直接支持Rails和PHP，也可以支持作为 HTTP代理服务器对外进行服务。
（4）Nginx 安装非常的简单，配置文件非常简洁（还能够支持perl语法）。Nginx支持平滑加载新的配置，还能够在不间断服务的情况下进行软件版本的升级。
