现在容器化技术越来越成熟和流行，比传统的虚拟化技术确实是有很大的优势，所以流行是必然的。今天来实践一把，使用Docker的dockerfile方式定制lnmp环境。
操作系统：CentOS Linux release 7.6.1810
Docker 版本：19.03.5
Nginx 版本：1.15.5
PHP 版本：7.2.26
MySQL 版本：8.0.18
Redis 版本：5.0.5 docker目录：//docker相关配置

<?php

$conn = mysqli_connect('数据库容器名字','dbuser','dbpw');
if($conn){
echo '数据库连接成功！';
}else{
echo '数据库连接失败！';
}
phpinfo();
?>
通过访问站点：http://www.zhangdetalk.com/
可以看到显示数据库连接成功，并打印出PHP的相关信息
到此步，我们的lnmp环境搭建大功告成！相关的源码下载地址：https://github.com/zhangdejian/docker_lnmp.git1、PHP代码连接数据库，host不能写成127.0.0.1或localhost，需要填写数据库容器名字
2、mysql8连接，连接失败，因为加密方式有变化
解决方式：主机登录mysql，修改成旧的加密方式（mysql_native_password），并重置密码
* mysql -uroot -p;
* use mysql;
* select host,user,plugin from user;
* alter user 'root'@'%' identified with mysql_native_password by '123456';可参考这篇文章：Docker 安装 MySQL8.0
