本地對我的Mac OS,我試圖連接到我的臨時數據庫運行,並在我的Ubuntu虛擬機託管。連接到從本地環境臨時數據庫 - Laravel 5


步驟

在我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.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 

我不知道該用什麼作爲我的UNIX_SOCKET因爲database.php中需要它。

我一直得到

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

我相信,因爲我的UNIX_SOCKET路徑是錯誤的。


問題

一個如何去和配置這樣的事?

如何進一步調試?


我打開此時的任何建議。

任何提示/建議/對此的幫助將非常感謝!


更新

基礎上@dparoli的答案。我更新我的數據庫配置,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, 
    ] 

], 

現在我

PDOException在Connector.php線49: SQLSTATE [HY000] [2002]操作超時


我試圖尋找更多進入我的設置staging VM

sshd_config

請問/etc/ssh/sshd_config在這個裏面扮演什麼角色? 是否因爲我禁用了密碼登錄並且只允許通過公共密鑰登錄?

我都試過

的PasswordAuthentication沒有

PasswordAuthentication yes把


netstat的

我跑netstat -ln,我

Active Internet connections (only servers)

結果

PDOException: SQLSTATE [HY000] [2002]操作超時

我該如何阻止?

還有什麼可以我檢查或嘗試?

我不認爲您可以使用unix套接字連接到遠程主機。你可能要做的是建立一個SSH隧道並通過隧道端口連接到本地主機。 –

+0

您是否檢查過您的MySQL權限,您是否允許從您嘗試訪問的主機訪問您輸入的用戶憑據? –

@ChrisTownsend:好想法!我試過,我得到了'ERROR 2003(HY000):無法連接到'45 .55.88.88'(60)' – ihue

您正在試圖通過一個Unix套接字連接到另一臺主機,這是不可能的原因插座,通常情況下,只對它們所創建的系統直接看到。

對於暫存ENV工作,你必須註釋掉unix_socket配置行,並添加端口:

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

並配置MySQL來偵聽該端口。

上的MySQL服務器我根據你的答案更新了我的數據庫配置。我得到了** SQLSTATE [HY000] [2002]操作超時**我也在帖子中添加了詳細信息。 – ihue

你必須配置mysql以進行遠程訪問,並在vm box防火牆中打開3306端口:看這裏:http://stackoverflow.com/questions/38905581/connection-error-sqlstatehy000-2002-operation-timed-out and here http://www.cyberciti.biz/tips/how-do-i-enable-remote-access-to-mysql-database-server.html – dparoli

我跑了'netstat -ln'我得到這個來顯示'tcp 0 0 0.0.0.0:3306 0.0.0.0:* LISTEN' – ihue

這似乎是在主機和客戶之間的主要是網絡問題。

  • 首先,讓我們的主機交談的遊客(VM)
    • 登錄到虛擬機(假設你使用VirtualBox的,其他的虛擬機將類似)
    • 運行ifconfig和記下IP地址。它會像10.0.2一樣。5
    • 轉到VM實例窗口 - >菜單 - >網絡適配器:
      • 一套適配器NAT
      • 點擊「端口轉發」底部
      • 創建新的記錄(點擊+圖標右手邊)
      • 設置主機IP = 127.0.0.1
      • 對於客人的IP地址輸入你早點起牀值(10.0.2.5 - 你的IP可能會有所不同)
      • 在這兩種情況下,端口使用3306
    • 兩次單擊OK按鈕,你應該出的設置屏幕,並全部完成
  • 驗證您可以通過命令行連接到MySQL實例在VM
    • 打開一個終端虛擬機上的窗口
    • 運行此命令mysql -hlocalhost -ujohn -p
    • 當出現提示時輸入密碼,您應該能夠連接。如果沒有,請嘗試以下
      • mysql -h127.0.0.1 -ujohn -p
      • 如果您仍然無法連接然後確保你有正確的密碼
    • 一旦你能夠在本地連接,它的時間從主機連接(蘋果機)
  • 使用以下命令:
    • mysql -h127.0.0.1 -ujohn -p
    • 提示
  • 時輸入密碼,如果您仍然無法連接,嘗試在客戶/ Ubuntu的關閉防火牆

,如果你有SSH訪問VM(你可以嘗試什麼或任何遠程實際),那麼你可以嘗試端口轉發連接在SSH:你的本地計算機上

ssh [email protected] -L 3307:localhost:3306 

現在端口3307行事作爲遠程機器上的端口3306。在您的配置文件,您可以然後去

DB_HOST=localhost 
DB_PORT=3307 

這種方法的缺點是,你需要有一個終端會話設置,當你想用你的本地環境中運行。

這是一個很酷的竅門,但我不確定,如果我想要始終連接到MySQL時繼續使用SSH。 – ihue

操作超時很可能是由防火牆引起的。你可以在你的虛擬機上運行這些命令解決這個問題:

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

如果不工作,檢查是否有使用此命令在端口3306的任何流量來:

sudo tcpdump -i eth1 port 3306 

更換eth1通過您的網絡接口,您可以使用以下命令找到:

sudo ip link show
