Install Unbuntu, username: gd, password: CGDC.
To small super super, server in 1.4.3x, play it together.
Installation Instructions:http://docs.mongodb.org/manual/tutorial/install-mongodb-on-ubuntu/
Because the MongoDB version of the Ubuntu official apt source is older, it is installed using the APT source provided by MongoDB.
To use the software on a third-party source, in addition to adding the corresponding source on the sources.list, add the corresponding public key key to properly install the software.

Client Shell:
Run./mongo can start the shell to manage MongoDB.
The shell uses Javascipt syntax to manage the data and to manage the database.

It's simple, there's nothing to say.

This syntax is this:
Use admin
Db.createuser ({
User: "Admin",
PWD: "CGDC",
Roles: [{
Role: "Useradminanydatabase",
DB: "Admin"
} ]
}
);
Db.createuser ({
User: "Root",
PWD: "CGDC",
Roles: [{role: "root", DB: "admin"}]
}
);
Use CGDC
Db.createuser ({
User: "CGDC",
PWD: "CGDC",
roles:[{
Role: "Dbowner",
DB: "CGDC"
}]
}
);
It's hard to use.

Look at the log.
Faint death, the log says, test database is not you want to even, want to even can practice. Of course, there is no user for test.
