这篇文章介绍了在Ubuntu 20.04.1 Desktop版本中配置LNMP（Linux+Nginx+Mysql+PHP）的步骤。作者先介绍了安装Nginx、PHP、Mysql和phpMyAdmin的方法，然后提到了禁止开机启动，需要手动打开的问题。文章还给出了一个提示，即如果在生产环境中不了解各项配置的含义，应避免按照本文进行配置。最后，作者还提到了一个奇怪的bug，即完全移除Apache2时出现的问题。
本文主要记录在 Ubuntu 20.04.1 Desktop 版本中配置 Nginx、Mysql、PHP、phpMyAdmin。
提示：如果不太了解各项配置的意思，切勿在服务器生产环境中按本文配置！

| sudo apt purge apache2* php7.0* mysql* phpmyadmin*
sudo apt autoremove
sudo apt autoclean
|
如果不能用*完全移除，可输入sudo apt purge apache2-然后按tab键一个一个删除。奇怪的 bug。
- 如果发生奇怪的事情，比如卸载
apache2的时候把桌面或者设置都卸载了，趁重启前重装一下。
