连接尝试失败，连接方未正确响应

Question

SQLSTATE[HY000] [2002] A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond. (SQL: SELECT * FROM users)

我想在我的本地项目中连接到我的远程数据库，但是当我这样做时出现上面列出的错误。它在我的另一个数据库（来自本地主机）中工作，我如何连接我的远程服务器数据库？

database.php

'mysql2' => [
    'driver' => 'mysql',
    'host' => 'domain.com',
    'port' => '3306',
    'database' => 'mybd',
    'username' => 'username',
    'password' => 'password',
    'charset' => 'utf8mb4',
    'collation' => 'utf8mb4_unicode_ci',
    'prefix' => '',
    'options' => ['mode' => 'ssl'],
    'strict' => false,
    'engine' => null,
]

控制器

public function test()
{
    $users = DB::connection('mysql2')->select("SELECT * FROM users");
    dd($users);
}

Answer 1

解决方案：

尝试从 'options'=>['mode'=>'ssl'] 中删除 SSL。
暂时禁用远程数据库上的防火墙（如果您有访问权限）只是为了测试。如果有效，则在您的远程服务器上允许或添加源 http://localhost。
使用 VM 或 docker，在其中之一上配置 SSL。
