Question

所以在节点中我有：

const mongoose = require('mongoose');

mongoose.connect('mongodb://localhost:27017/master');
let db = mongoose.connection();
db.on('error', console.error.bind(console, 'connection error:'));
db.once('open', function() {
  // we're connected!
  console.log('conn');
});

但是没有打印出来，如果我尝试从节点查询数据库，它会永久挂起而不会出现错误。我可以打开mongo shell并创建一个新的集合，插入项目等。

这是Mongo的日志：

Answer 1

尝试：

  this.connection = mongoose.createConnection('mongodb://localhost:27017', { server: { reconnectTries: Number.MAX_VALUE } });

但是，您必须以不同的方式创建模型。看看here

Answer 2

通过使用node卸载并重新安装mongodb和brew然后重新启动并重新安装（确保删除项目存储库中的node_modules并重新安装）来解决此问题。

MongoDB从不响应但接受连接
