Doctrine無法使用Mamp連接到Symfony2中的數據庫

Question

我正在嘗試通過學說創建數據庫。

php app/console doctrine:database:create

當我運行上述命令時，出現以下錯誤：

[Doctrine\DBAL\Exception\ConnectionException]                              
An exception occured in driver: SQLSTATE[HY000] [2002] Connection refused  



[Doctrine\DBAL\Driver\PDOException]        
SQLSTATE[HY000] [2002] Connection refused  



[PDOException]                             
SQLSTATE[HY000] [2002] Connection refused

我嘗試過的

這種符號鏈接的創建對我不起作用。

sudo ln -s /Applications/MAMP/tmp/mysql/mysql.sock mysql.sock

我已經嘗試了database_host: localhost和database_host: 127.0.0.1沒什么變化。

我知道在MAMP上可以看到我的MySQL端口是8889 。

由於我沒有MAMP Pro，因此無法在MAMP的MySQL選項卡下選中允許網絡訪問 MySQL選項

這是我的配置文件

Answer 1

php app/console cache:clear

問題是由於緩存，無論我做什么都收到錯誤消息。 上面的命令清除了緩存，並將MAMP和paramteters.yml中的數據庫端口更改為3306，已解決了該問題。

Answer 2

檢查您的DNS設置。 如果您不使用VPN，請將其關閉。

您可以使用“ Sequel PRO”測試連接

主機名：本地主機-127.0.0.1-IP地址

密碼：1234-root

如果他們不能解決問題，請檢查用戶權限。
