Question

我尝试从NodeJS App连接到MongoDB。

连接正在我的本地计算机上运行，所以它必须是我的OpenShift的问题。

在我的服务器代码中，我使用：

mongoose.connect(process.env.OPENSHIFT_MONGODB_DB_URL)

但是我在日志中遇到以下错误：

DEBUG: Starting child process with 'node server/server.js'
Warning: connect.session() MemoryStore is not
designed for a production environment, as it will leak
memory, and will not scale past a single process.
