mongodb - MongoDB 3.0.1 mongodump错误

Question

我需要使用“mongodump”创建MongoDB数据库的转储文件。

    ubuntu-0864947@ubuntu-vm:~$ mongo
    MongoDB shell version: 3.0.1
    connecting to: test
    Server has startup warnings: 
    2015-03-30T14:26:08.806+0200 I CONTROL  [initandlisten] ** WARNING: You are running this process as the root user, which is not recommended.

    2015-03-30T14:26:08.808+0200 I CONTROL  [initandlisten] 
    > mongodump
    2015-04-30T15:56:00.719+0200 E QUERY    ReferenceError: mongodump is not defined

    > mongodump RotterdamHaven

    switched to db RotterdamHaven
    > mongodump RotterdamHaven
    2015-04-30T16:26:13.742+0200 E QUERY    SyntaxError: Unexpected identifier

有人可以告诉我我在做什么错吗？

谢谢!

mongodump是类似于mongo的可执行文件，您需要在OS Shell中而不是在MongoDB Shell中执行它:

ubuntu-0864947@ubuntu-vm:~$ mongodump <arguments>
