Question

我正在尝试将在我的机器上运行的wordpress连接到远程mysql数据库，该数据库通过我的机器（localhost）进行隧道传输。数据库连接通过向mysql CLI客户端

提供以下参数来工作

$ mysql --protocol=TCP -P 10000 -h localhost -u username -p'password' db_name

在wordpress的wp-config.php文件中，我尝试了以下值：

define('DB_NAME', 'db_name');
define('DB_USER', 'username');
define('DB_PASSWORD', 'password');
define('DB_HOST', 'localhost');
define('DB_PORT', 10000);

这不起作用＆amp;抛出以下错误：

Warning: include(/home/gaurish/Dropbox/code/projects/blog/wp-content/advanced-cache.php): failed to open stream: No such file or directory in /home/gaurish/Dropbox/code/projects/blog/wp-settings.php on line 62 
Warning: include(): Failed opening '/home/gaurish/Dropbox/code/projects/blog/wp-content/advanced-cache.php' for inclusion (include_path='.:/usr/share/php:/usr/share/pear') in /home/gaurish/Dropbox/code/projects/blog/wp-settings.php on line 62 
Warning: mysql_connect(): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2) in /home/gaurish/Dropbox/code/projects/blog/wp-includes/wp-db.php on line 1038

上述错误（Can't connect to local MySQL server through socket）中的最后一行是为什么连接失败，因为wordpress试图通过unix套接字连接。

现在，我需要设置哪些参数才能将wordpress连接到数据库方式mysql CLI客户端？

Answer 1

如果您想通过TCP而不是Unix套接字进行连接，请尝试将主机从localhost更改为127.0.0.1。

define('DB_HOST', '127.0.0.1');  // forces TCP

Answer 2

我能够使用wp-config.php中的以下设置进行连接。

define('DB_NAME', 'db_name');
define('DB_USER', 'username');
define('DB_PASSWORD', 'password');
define('DB_HOST', '127.0.0.1:10000');
define('DB_PORT', 10000);

数据库连接成功：）
