简介 LEMP是用来搭建动态网站的一组软件，首字母缩写分别表示Linux、Nginx（Engine-X）、MySQL和PHP。 本文将讲述如何在Ubuntu安装LEMP套件。当然，首先要安装Ubuntu18.04操作系统，接着按照以下方法完成其他组建的安装。 1.切换root用户 输入命令： su root 回车提示输入密码，怎么输入都不对，这是你的root没有设置密码或者你当前就是root 给root用户设置密码：命令： sudo passwd root 输入密码，并确认密码。 重新输入命令： su root 然后输入密码： 发现可以切换到root权限了。 使用su xyx命令，切换到普通用户。 2.以下演示将通过非管理员账号进行，即通过sudo命令完成安装 如果是普通账号（非管理员）可继续往下看。 管理员可以去掉sudo直接使用命令 步骤一：安装Nginx网站服务器 $ sudo apt update $ sudo apt install nginx 在Ubuntu上，使用以上两条命令完成nginx安装就可以通过localhost访问了，若访问失败，可能是已经安装了Apache等占用80端口的服务，或者是防火墙问题，若访问成功，应该如下图所示。 步骤二：安装MySQL数据库 $ sudo apt install mysql-server-5.7 执行该条命令安装MySQL
