我的行爲出了什麼問題？

Answer 1

看起來像是在試圖遠程連接到設備的mysql實例。如果要簡化此步驟，我們有端口轉發工具：https://openshift.redhat.com/community/blogs/getting-started-with-port-forwarding-on-openshift
否則，您需要使用$ UUID作爲代理用戶，並且一旦連接，您的本地連接應該是127.0.0.1:48729

看起來像您的管理員用戶的值可能不正確。請ssh登錄到你的設備（rhc ssh {appName}）並運行「env | grep OPENSHIFT_MYSQL」列出存儲連接詳細信息的變量。

的jdbc：mysql的：//127.11.103.129：3306 /項目假定：

127.11.103.129 == $OPENSHIFT_MYSQL_DB_HOST 
3306 == $OPENSHIFT_MYSQL_DB_PORT 
project == $OPENSHIFT_APP_NAME 

如果任何這些值不正確，請使用正確的價值觀爲好。
