从本地环境连接到临时数据库 - Laravel 5

标签： mysql laravel ubuntu laravel-5 database-connection

目标

我的 Mac OS 本地，我正在尝试连接到我的Ubuntu VM上运行和托管的登台数据库。

的步骤

在我的config/database.php

中 
'connections' => [

    'mysql'       => [
    'driver'      => 'mysql',
    'host'        => env('DB_HOST'),
    'database'    => env('DB_DATABASE'),
    'username'    => env('DB_USERNAME'),
    'password'    => env('DB_PASSWORD'),
    'unix_socket' => env('UNIX_SOCKET'), <---- Need it here 
    'charset'     => 'utf8',
    'collation'   => 'utf8_unicode_ci',
    'prefix'      => '',
    'strict'      => false,
    ]

],

在我的.env中我有

DB_HOST=45.55.88.88
DB_DATABASE=staging
DB_USERNAME=john
DB_PASSWORD=***
UNIX_SOCKET=/var/run/mysqld/mysqld.sock  <---- I'm not sure what to put here

由于database.php需要它，我不确定要将什么作为我的UNIX_SOCKET。

我一直在

SQLSTATE[HY000] [2002] No such file or directory

我相信因为我的UNIX_SOCKET路径错误。

问题

如何进行并配置这样的东西？

如何继续进行调试？

我现在正在接受任何建议。

任何提示/建议/帮助都将非常感谢！

更新

基于 @dparoli 的回答。我不再使用 UNIX_SOCKET 更新我的数据库配置。 

'connections' => [

    'mysql'       => [

        'driver'      => 'mysql',
        'host'        => env('DB_HOST'),
        'database'    => env('DB_DATABASE'),
        'username'    => env('DB_USERNAME'),
        'password'    => env('DB_PASSWORD'),
        'port'        => env('DB_PORT', '3306'),
        'charset'     => 'utf8',
        'collation'   => 'utf8_unicode_ci',
        'prefix'      => '',
        'strict'      => false,
    ]

],

现在我得到了

  

Connector.php第49行中的PDOException：   SQLSTATE [HY000] [2002]操作超时

我已经尝试了解staging VM

的设置

的sshd_config

/etc/ssh/sshd_config会扮演这个角色吗？ 是因为我禁用了密码登录，只允许通过公钥登录？

我已经尝试过两次

PasswordAuthentication no

和

PasswordAuthentication yes

的netstat

我跑了netstat -ln，我得到了

Active Internet connections (only servers)
Proto Recv-Q Send-Q Local Address           Foreign Address         State      
tcp        0      0 0.0.0.0:22              0.0.0.0:*               LISTEN

我在那里看到 0 0.0.0.0:3306 。

我怎么能阻止它？

我还可以查看或尝试什么？

您正在尝试通过unix套接字连接到另一台主机，这是不可能的，因为通常，套接字只能直接显示在创建它们的系统上。

要使你的staging环境工作，你必须注释掉unix_socket配置行并添加一个端口：

'port' => env('DB_PORT', '3306'),

并配置mysql以侦听该端口。

这似乎主要是主持人与访客之间的网络问题。

  • 首先，让我们让主持人与访客（VM）交谈
    • 登录VM（假设您使用的是VirtualBox，其他虚拟机将类似）
    • 运行ifconfig并记下IP地址。它将类似于10.0.2.5
    • 转到VM实例窗口 - ＆gt;菜单 - ＆gt;网络适​​配器：
      • 将适配器设置为NAT
      • 点击底部的“端口转发”
      • 创建新记录（单击右侧的+图标）
      • 设置主机IP = 127.0.0.1
      • 对于访客IP地址，请输入您之前获得的值（10.0.2.5 - 您的IP可能不同）
      • 在两种情况下都使用端口3306
    • 单击“确定”按钮两次，您应该不在设置屏幕中并且全部完成
  • 验证您是否可以通过VM上的命令行连接到MySQL实例
    • 在VM上打开终端窗口
    • 运行此命令mysql -hlocalhost -ujohn -p
    • 出现提示时输入密码，您应该能够连接。如果没有，请尝试以下操作
      • mysql -h127.0.0.1 -ujohn -p
      • 如果仍然无法连接，请确保您拥有正确的密码
    • 一旦您能够在本地连接，就可以从主机（Mac）
      • 进行连接
  • 使用以下命令：
    • mysql -h127.0.0.1 -ujohn -p
    • 提示时输入密码
  • 如果仍然无法连接，请尝试关闭Guest / Ubuntu上的防火墙

答案 2 :(得分：1)

如果您SSH访问VM（或实际上任何远程），您可以尝试使用，然后您可以尝试通过SSH端口转发连接：

ssh foo@bar -L 3307:localhost:3306

现在，本地计算机上的端口3307充当远程计算机上的端口3306。在配置文件中，您可以进入

DB_HOST=localhost
DB_PORT=3307

这种方法的缺点是，当您想要使用本地环境时，需要设置终端会话并运行。

答案 3 :(得分：1)

操作超时很可能是由防火墙引起的。您可以通过在VM上运行以下命令来解决此问题：

sudo ufw allow out 3306/tcp
sudo ufw allow in 3306/tcp

如果这不起作用，请使用以下命令检查端口3306上是否有任何流量：

sudo tcpdump -i eth1 port 3306

用网络接口替换eth1，您可以使用以下命令找到它：

sudo ip link show
