我在MongoDB Atlas上设置了一个集群，让自己成为了管理员，但是我无法从shell连接到集群。在Atlas上，我点击了连接按钮，点击了与Mongo Shell的连接，下载了最新的Mongo Shell，并复制了命令以连接到集群：
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>
当我运行此命令时，我得到了流：

我用我的用户名和密码替换了，但我仍然无法连接。我需要让mongod在后台运行吗？如果不是我需要做什么才能成功连接？谢谢。

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。

我的问题是我最近才在Atlas UI中设置/更改密码-他们花一分钟左右的时间来部署所有更改，甚至重置密码等。等到更改后，我才能登录待部署

与其他人一样，不喜欢我的战俘。从命令行可以正常工作，但不能从Compass正常工作。检查故障排除页面https://docs.atlas.mongodb.com/troubleshoot-connection/#special-characters-in-connection-string-password。我的密码中有特殊字符。尝试将它们转义，然后回过头将我的密码重置为一些没有特殊字符的简单密码-花费了一分钟，但随后我轻松连接了。
答案 3 :(得分：0)
只需从密码中删除特殊字符即可。

有时值得重置本地服务。运行 where to_char(to_date(month_name,'MONTH'),'Q') =
to_char(add_months(sysdate,9),'Q');
，然后运行 brew services stop mongodb-community。
