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，该数据库在我的机器(本地主机)上建立隧道。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
Reading table information for completion of table and column names
You can turn off this feature to get a quicker startup with -A

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);
这不起作用并抛出以下错误:
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

上述错误(无法通过套接字连接到本地 MySQL 服务器)中的最后一行说明了连接失败的原因，因为 wordpress 正在尝试通过 unix 套接字进行连接。
现在，我需要设置哪些参数才能让 wordpress 作为 mysql CLI 客户端连接到数据库？
最佳答案
如果您想通过 TCP 而不是 Unix 套接字连接，请尝试将主机从 localhost 更改为 127.0.0.1。
define('DB_HOST', '127.0.0.1'); // forces TCP
