使用 SSH 的 Laravel MySql 数据库连接

2022-01-08 00:00:00 ssh mysql laravel-4

我有几个想要访问的远程数据库，但它们位于只能通过带有密钥的 SSH 访问的服务器上.

I have a couple of remote databases I would like to access, but they are sitting on a server accessible only through SSH with a key.

在 Sequel Pro 中，我连接到这个远程数据库，如下所示:

In Sequel Pro, I connect to this remote DB something like this:

如何配置我的 Laravel 应用程序以连接到这样的数据库?

How would I configure my Laravel app to connect to such a DB?

'mysql_EC2' => array(
        'driver'    => 'mysql',
        'host'      => '54.111.222.333',
        'database' => 'remote_db',
        'username' => 'ubuntu',
        'password' => 'xxxxxxxxxxxxxxxxxxxx',
        'charset'   => 'utf8',
        'collation' => 'utf8_unicode_ci',
        'prefix'    => '',
    ),

推荐答案

这是一个可行的解决方案，通过带有密钥的 SSH 使用托管在 EC2 实例上的数据库.

Here's a workable solution of working with a database hosted on an EC2 instance via SSH w/ a key.

首先，在您的数据库配置中设置相应的连接:

First, setup a corresponding connection in your database config:

'mysql_EC2' => array(
        'driver'    => 'mysql',
        'host'      => '127.0.0.1:13306',
        'database' => 'EC2_website',
        'username' => 'root',
        'password' => 'xxxxxxxxxxxxxxxx',
        'charset'   => 'utf8',
        'collation' => 'utf8_unicode_ci',
        'prefix'    => '',
    ),

其次，建立隧道:

ssh -i ~/dev/awskey.pem -N -L 13306:127.0.0.1:3306 ubuntu@54.111.222.333

(我们将 SSH 密钥传递给 i 参数并建立 SSH 连接，绑定到端口 13306)

(we pass in the SSH key to the i parameter and establish an SSH connection, binding to port 13306)

第三，像在 Laravel 应用程序中一样使用 DB:

Third, use the DB how you normally would in a Laravel App:

$users = DB::connection('mysql_EC2')
        ->table('users')
        ->get();

var_dump($users);
