我剛剛進入OpenShift，請耐心等待。我在我的域中設置了一個MySQL數據庫，並且能夠從phpMyAdmin頁面添加和刪除項目。我現在想在我的機器上創建一個應用程序，並且只在我的機器上連接到數據庫，並且能夠具有讀/寫訪問權限。我已經爲這個用戶設置了一個權限集，併爲C＃編寫了一個表單。我已經執行了以下內容：連接到OpenShift服務
rhc port-forward --app <my application name>
事後，我收到如下：
W:\>rhc port-forward --app <my application name>
DL is deprecated, please use Fiddle
Checking available ports ... done
Forwarding ports ...
Only one usage of each socket address (protocol/network address/port) is
normally permitted. - bind(2) while forwarding port 8080. Trying local port 8081
To connect to a service running on OpenShift, use the Local address
Service Local OpenShift
httpd 127.0.0.1:8080 => 127.3.223.1:8080
httpd 127.0.0.1:8081 => 127.3.223.3:8080
mysql 127.0.0.1:3306 => 127.3.223.2:3306
Press CTRL-C to terminate port forwarding
因此，當我重新回到C＃，我有下面的代碼行：
conn = new SqlConnection("user id="+tbUser.Text+";password="+tbPass.Text+";server=127.0.0.1:3306;database=<my application name>");
conn.Open();
但我得到.Open（）函數的錯誤，說它找不到服務器或數據庫。我對正在發生的事情不知所措。
編輯：我想我還不如添加如果在所有有用的錯誤消息：
An unhandled exception of type 'System.Data.SqlClient.SqlException' occurred in System.Data.dll
