推荐答案

你的 show dbs 输出只有一个 db，local，它是自动创建的.如果您在启动时没有指定数据库，mongo shell 默认为 test，这就是您看到connecting to: test"的原因.直到您开始将数据插入其中的集合中，才会创建数据库 test.

Your show dbs output only has one db, local, which is created automatically. If you don't specify a database on startup the mongo shell defaults to test which is why you see "connecting to: test". The database test will not be created until you start inserting data into a collection in it.
