从本地环境连接到分段数据库
目标
在我的Mac OS上 ，我尝试连接到运行并托管在我的Ubuntu VM上的暂存数据库 。
脚步
在我的config/database.php
'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
因为database.php需要它，所以我不确定要把PUT作为我的UNIX_SOCKET。
我不断收到
SQLSTATE[HY000] [2002] No such file or directory
我相信因为我的UNIX_SOCKET路径是错误的。
问题
人们会如何去配置和配置这样的东西？
如何进一步进行调试？
我现在正在接受任何建议。
任何提示/建议/对此的帮助将非常感谢！
更新
基于@dparoli的回答。 我更新我的数据库配置不再使用UNIX_SOCKET 。
'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中的PDOException第49行：SQLSTATE [HY000] [2002]操作超时
我试着更多地了解我的staging虚拟机的设置
sshd_config中
/etc/ssh/sshd_config在这里扮演任何角色吗？ 是否因为我禁用了密码登录并且只允许通过公共密钥登录？
我已经尝试了两种
PasswordAuthentication no
和
PasswordAuthentication yes
netstat的
我跑了netstat -ln ，我得到了
Active Internet connections (only servers)

结果

我怎么能阻止呢？
我还能检查或尝试什么？
您正尝试通过unix套接字连接到另一台主机，这是不可能的，因为套接字通常只能在创建它们的系统上直接看到。
为了让你的分段环境工作，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Host和Guest之间的网络问题。
mysql -hlocalhost -ujohn -p mysql -h127.0.0.1 -ujohn -p mysql -h127.0.0.1 -ujohn -p 如果你有SSH访问虚拟机（或实际上任何远程）的东西，你可以尝试什么，那么你可以尝试通过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 。 在你的配置文件中，你可以去
DB_HOST=localhost
DB_PORT=3307
这种方法的缺点是，当你想使用你的本地环境时，你需要安装终端会话并运行。
