Question

我刚刚在Laravel 5.1中构建了我的新应用程序，我试图推动它。当我尝试编写器安装时，我收到此错误。

[PDOException]                                                                     
SQLSTATE[HY000] [1045] Access denied for user ''@'localhost' (using password: NO)  

Script php artisan clear-compiled handling the post-install-cmd event returned with an error

[RuntimeException]  
Error Output:

我在本地和制作上都使用环境文件，所以我不知道最近会发生什么。有什么想法吗？

就像我的环境文件没有被伪造的那样......

Answer 1

之所以发生这种情况，是因为我正在使用伪造的“安装回购”功能来安装我的完整项目。现在因为服务器上没有设置环境，所以在安装时失败了。

为了解决这个问题，我不得不对生产数据库凭据进行硬编码，安装repo然后创建env文件。然后，一旦完成，删除硬编码凭证（我不知道）。

似乎在安装之前设置.env也不起作用。因此，如果从构建开始就在服务器上安装了repo，就不会遇到这类问题。

但我的项目现已正常运行。谢谢你的回复。

Answer 2

发生这种情况的原因是因为forge正在您的项目上运行post install命令，并且您可能正在访问您的某个服务提供商中的数据库，因为它可能是您想要附加到您的视图的变量，请尝试评论服务提供程序中的代码，安装存储库然后再次推送代码它应该可以正常工作

确保MySQL用户在连接MySQL时拥有给定ip的所有访问权限。如需进一步参考，请浏览以下链接。

Answer 4

如果没有看到.env文件，很难说肯定，但看起来它从某个地方拿起用户名 - 默认是＆＃39;伪造＆＃39;然而错误消息的用户名为空字符串 - ＆＃39;＆＃39; @localhost。

检查你的env文件，确保=后面没有空格，并且变量名与数据库配置中的变量名匹配。我还有一些问题需要将密码和其他具有特殊字符的值包装在＆＃39;＆＃39;中。最后，请记住这个案例很重要 - 我已经看到了一切都在本地工作但在开发服务器上失败的问题，因为有人改变了变量的情况。我的mac并不关心，但ubuntu服务器确实如此。

Answer 5

试试这个

1

in app/database.php

Replace localhost with 127.0.0.1

'host'=> env('DB_HOST', 'localhost') -->'host' => env('DB_HOST', '127.0.0.1')

Also, in .env

DB_HOST=localhost --> DB_HOST=127.0.0.1

2

Try specify environment

php artisan migrate --env=local

3

Check to see if the MySQL is running by run

mysqladmin -u homestead -p status Enter password: secret

I got

Uptime: 21281 Threads: 3 Questions: 274 Slow queries: 0 Opens: 327 Flush tables: 1 Open tables: 80 Queries per second avg: 0.012

Which mean it's running.

4

Check MySQL UNIX Socket

5 确保你的.env文件看起来像这样：

APP_ENV=local
APP_DEBUG=true
APP_KEY=YOURAPPKEY

DB_HOST=localhost
DB_DATABASE=YOURDBNAME
DB_USERNAME=YOURPHPMYADMINUSERNAME
DB_PASSWORD=YOURPHPMYADMINPASS

6

try changing localhost into 127.0.0.1 in .env DB_HOST or try add your mysql port
