重新启动Openshift MySQL墨盒时出错 [英] Error restarting Openshift MySQL cartridge
问题描述
我有一个不可扩展的OpenShift应用程序，该应用程序具有 Tomcat 7 和 MySQL 5.5 ，并且该应用程序上仅运行了一个小型Java应用程序.该应用程序运行了好几个月，但是从上周开始它停止工作了.当我尝试使用OpenShift仪表板重新启动应用程序时，出现以下错误消息:
I have a non-scalable OpenShift application with Tomcat 7 and MySQL 5.5 and this application has only one small Java application running on it. This application was running fine for a couple of months but since last week it stopped working. When I try to restart the application using the OpenShift dashboard I get the following error message:

显然，MySQL盒式服务器无法以某种方式重新启动，但是我没有更改Java应用程序或齿轮配置中的任何内容.
Apparently the MySQL cartridge is failing to restart somehow, but I didn't change anything in my Java application or the gear configuration.
有人知道为什么会这样吗?我不想简单地删除MySQL并再次添加它，因为如果我不确定根本原因，将来可能会再次发生此问题.
Does anybody know why this is happening? I don't want to simply remove MySQL and add it again because this problem may happen again in the future if I don't identify the root cause.
谢谢.
推荐答案
我建议检查您的配额，以查看您是否已达到限额.尝试摆弄齿轮并运行以下quota -s.如果已达到配额，则可以在本地计算机上使用rhc tidy命令清理齿轮.
I would suggest checking your quota to see if you've reached your limit. Try ssh'ing into your gear and running the following quota -s. If you've reached your quota then you can use the rhc tidy command on your local machine to clean up the gear.
