我在 MongoDB Atlas 上设置了一个集群并让自己成为管理员，但我无法从 shell 连接到集群。在Atlas上，我点击了connect按钮，点击connect with Mongo Shell，下载了最新的Mongo Shell，复制了连接集群的命令:

mongo "mongodb://testcluster-shard-00-00-acqhf.mongodb.net:27017,testcluster-shard-00-01-acqhf.mongodb.net:27017,testcluster-shard-00-02-acqhf.mongodb.net:27017/test?replicaSet=TestCluster-shard-0" --authenticationDatabase admin --ssl --username <USERNAME> --password <PASSWORD>

当我运行这个命令时，我得到了流:

我将 and 替换为我的用户名和密码，但仍然无法连接。我需要在后台运行 mongod 吗？如果不是，我需要做什么才能成功连接？谢谢。

最佳答案

我必须使用不同的用户名和密码创建一个新用户，当我使用这些新凭据运行命令时，我可以连接。
