mysql - 在 openshift 上部署 grails war 文件后显示空白页

Question

在使用以下指南创建 tomcat 7(JBoss EWS 2.0) 应用程序后，我将 war 文件部署到 openshift (deploy war file using git)但在部署我的应用程序后，它只显示一个空白页面。这是我使用 rhc tail 命令获得的日志。

我部署的 war 文件的名称是 ROOT.war 使用 git push 并且部署成功。我正在使用 mysql 数据库和 phpmyadmin 墨盒。我只是想弄清楚为什么当我尝试访问我的应用程序的 url 时它会显示一个空白页面。

提前致谢。

你提供的日志一点帮助都没有，因为它不完整，我什至看不到抛出什么异常。

这是关于在 OpenShift 上部署 grails 应用程序的最佳文章，它将对您有很大帮助: Grails on Openshift

此外，如果您使用 ftp 查看服务器上发生的情况，故障排除会更有效率 Using FileZilla and SFTP on Windows with OpenShift
