How to put username &password in MongoDB(Security&Authentication)?(配置用户认证在MongoDB)

Default do not need username and password authenticate when access mongoDB ,I want to set up the user name & password for my mongoDB. so that any remote access will ask for the user name & password. one way is following:

Shutdown Server and exit
Restart Mongod with –auth option or using config file.

tip:
The username & password will work the same for mongodump and mongoexport.

TIP:
Deprecated since version 2.6: Use db.createUser() and db.updateUser() instead of db.addUser() to add users to MongoDB.



db.createUser( { "user" : "anbob",
                 "pwd": "mongo",                
                 "roles" : [ { role: "clusterAdmin", db: "admin" },

                             "readWrite"
                             ] },
