我在parametes.yml检查的价值观和我发誓，他们是正确的

数据库端口通常是3306 – Scriptable

可能是主机不正确。许多托管服务在不同的机器上都有数据库 – Volvox

我更新我的代码，请检查。 – phpmeter

标准MySQL端口是3306，除非你已经被你的供应商使用该另一端口告诉，你应该坚持默认。

尝试手动连接通过终端：通过添加-h即-h127.0.0.1

如果

mysql -uswipecom_swipe -p localhost

，如果你确实是一个不同的端口上运行添加-P8889的命令，你也可以选择一台主机仍然不起作用，请确保密码正确并检查用户是否可以从本地主机访问。

我在cpanel中运行应用程序。我没有终端来检查它。 – phpmeter

在cpanel，转到Mysql数据库并检查数据库名称，用户和访问 – Scriptable

我检查了数据库名称，甚至是用户名和密码，但仍然无法连接？ – phpmeter
