Question

我在Google Compute Engine实例上有一个KeystoneJS应用，在我的项目文件夹中执行mongod和npm start之后，我运行gcloud app deploy并得到以下错误：

Mongoose connection "error" event fired with:
{ MongoError: failed to connect to server [localhost:27017] on first connect

我在MongoDB或KeystoneJS方面经验不足，因此非常感谢

似乎在部署到GAE时，您保留了到本地托管mongo数据库的默认连接。（failed to connect to server [localhost:27017]）

由于GAE环境中没有运行mongodb，因此您必须创建一个mongo数据库（您可以在此处使用许多不同的mongodb服务），并使用MONGO_URI env变量来设置项目。

Keystonejs然后将尝试连接您在此变量中设置的数据库。

我希望此评论对您有帮助，如果您在设置所有内容时仍然遇到问题，可以向我们展示您的app.yaml文件;）

KeystoneJS应用无法在Google App Engine上部署
