我正在尝试在 this 之后的 Ubuntu 14.04 上设置 WordPress教程。编辑 wp-config.php
,我遇到了 “Error establishing a database connection”
错误。
define('DB_NAME', 'wordpress');
/** MySQL database username */
define('DB_USER', 'wordpressuser');
/** MySQL database password */
define('DB_PASSWORD', 'wordpress');
/** MySQL hostname */
define('DB_HOST', 'localhost');
/** Database Charset to use in creating database tables. */
define('DB_CHARSET', 'utf8');
/** The Database Collate type. Don't change this if in doubt. */
define('DB_COLLATE', '');
define('WP_ALLOW_REPAIR', true);
DB_NAME
、DB_USER
和 DB_PASSWORD
的值是正确的。我不确定 DB_HOST
;我试过了:
define('DB_HOST', 'localhost:3306');
define('DB_HOST', '127.0.1.1');
define('DB_HOST', '127.0.1.1:3306');
define('DB_HOST', '159.203.70.104');
define('DB_HOST', '159.203.70.104:3306');
但都没有解决问题。 MySQL 和 Apache 日志没有显示任何关于错误的信息。 MySQL shell 输出:
mysql -u root -p
Enter password:

重新启动 MySQL 没有帮助。 wordpressuser
的 Shell 输出:
mysql -u wordpressuser -p

最佳答案
您应该能够通过执行以下操作来修复:
创建新用户:
CREATE USER 'wordpressuser'@'127.0.0.1' IDENTIFIED BY 'password';
(将'密码')更改为您的密码
授予此用户对 wordpress 数据库的权限:
GRANT ALL PRIVILEGES ON wordpress . * TO 'newuser'@'127.0.0.1';
最后通过编辑配置文件使用 127.0.0.1 作为数据库主机:
define('DB_HOST', '127.0.1.1');
如果用户没有使用它的授权,则不能将 127.0.0.1 用作数据库主机
