WordPress会把数据库的相关信息存在wp-config.php文件中。如果编辑有问题，则会出现建立数据库连接时出错 问题。
有的wordpress中可能没有wp-config.php文件，有的是wp-config-sample.php文件，这时候就需要我们复制一份。
cp /wordpress/wp-config-sample.php /wordpress/wp-config.php接下来就可以开始编辑wp-config.php文件啦~
vi /wordpress/wp-config.phpwp-config.php文件全部内容：
<?php

* This file contains the following configurations:
*
* * MySQL settings
* * Secret keys
* * Database table prefix

修改wp-config.ph文件中的数据库设置：
将 database_name_here 修改为自己的数据库名称。
将 username_here 修改为自己的数据库用户名。
将 password_here 修改为自己的数据库密码。
localhost ：数据库主机名。
utf8 : 数据库字符集。
设置wp-config.ph文件中的密钥部分

如果您希望在同一个数据库中安装多个WordPress，请修改前缀。一般默认为 wp_
设置绝对路径
这一段用于设置WordPress变量和包含的文件，不需要修改！
