如何编辑WordPress配置文件wp-config.php

wp-config.php文件全部内容：

修改wp-config.ph文件中的数据库设置：

设置wp-config.ph文件中的密钥部分

修改数据库表前缀

设置绝对路径

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.php

wp-config.php文件全部内容：

if ( !defined('ABSPATH') )

    define('ABSPATH', dirname(__FILE__) . '/');

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。
