1、点开xampp里面的Volumes，找到下面的Explore，点击进入。
2、找到htdocs文件夹，点击进入。
3、找到wordpress文件夹，点击进入。
4、这时候你可以看到很多带".php"后缀的文件，随意复制一个。我复制的是wp-config-sample.php，之后用wi荏鱿胫协ndows的记事本或者mac的文本编辑器打开，将里面的内容全部删掉。
5、将下面的这段代码全部复制进上一步打开的那个“.php“文件里。<?php/*** The base configuration for WordPress** The wp-config.php creation script uses this file during the* installation.

6、找到这个文件顶部的“已编辑”，点开重命名为“wp-config.php“，回车保存。
7、做完这些之后，亲测Error establishing a database connection已消失。
