#2
In MongoDB, to create a database from within the Mongo shell you use
在MongoDB中,要从您使用的Mongo shell中创建数据库
use mydatabasename
where mydatabasename is the name you want to give to the database. If you want to list the databases

show dbs
The shell quick reference documentation is pretty good.
shell快速参考文档非常好。
