由于内存泄漏，Grails 应用程序无法部署到 Cloudfoundry答案

【问题标题】：Grails app fail to deploy to cloudfoundry due to memory leaks由于内存泄漏，Grails 应用程序无法部署到 Cloudfoundry
【发布时间】：2012-09-12 11:49:34
【问题描述】：

我有一个 grails 2.1.0 应用程序，我可以成功地将它部署到 cloudfoundry。经过一些代码更改后，我做了一个 grails prod cf-update，一切都崩溃了。我试图删除 cloudfoundry 应用程序并重新创建它，但没有结果。

这是来自 grails cf-chrashlogs 的日志

【解决方案1】：

您是否在项目中的任何位置创建了表？

表 'dc2baf5ca87094d6099e1ac613db0eaad.club' 不存在
表 'dc2baf5ca87094d6099e1ac613db0eaad.judoka' 不存在
表 'dc2baf5ca87094d6099e1ac613db0eaad.category' 不存在
表 'dc2baf5ca87094d6099e1ac613db0eaad.championship' 不存在

【讨论】：

我有以下 DataSource.groovy。使用这种配置，它在几天前就可以工作了。类别、俱乐部等是 grails 域对象。他们的表应该是在 MySQL 中自动创建的，不是吗？生产 { 数据源 { 方言 = org.hibernate.dialect.MySQL5InnoDBDialect driverClassName = 'com.mysql.jdbc.Driver' 用户名 = 'n/a' 密码 = 'n/a' url = 'jdbc:mysql://localhost/db ?useUnicode=true&characterEncoding=utf8' dbCreate = 'update' } }
是的，如果您在 DataSource 配置中有“dbCreate='update'”，则会自动创建缺失的表。那么您能否确认在 projectRoot/grails-app/domain/ 下创建了这样的域类。而且您还使用推送了应用程序
好吧，我在 cloudfoundry.com 上创建了一个新帐户，使用这些新凭据我可以成功部署我的应用程序...无需任何更改！所以，我猜这不是我的应用程序的错，但是，问题出在哪里？我该如何解决？谢谢！
目前我很难重现您的问题。但既然你可以在一个单独的环境中制作它，也许你想从头开始尝试。正如您所提到的，首先通过以下方式删除您的应用程序：grails cf-delete-app。 2、通过：grails cf-create-service mysql [name]提供一个新的mysql服务。推送您的应用程序并确保绑定新服务。这应该可以正常工作。
是的，William，我已经尝试使用我的第一个 cloudfoundry 帐户从头开始，但没有成功......唯一不同的是我没有通过“grails cf”创建 mysql 服务-create-service mysql [名称]”。当被要求创建它并在执行“grails prod cf-push”时绑定它时，我只是说“是”。
