Log on to MongoDB shell and switch to the admin database

Use admin

Create administrator user

Db. createUser (
User: "yourusername ",
Pwd: "password ",
Roles: [{role: "userAdminAnyDatabase", db: "admin"}]

Modify/etc/init. d/mongod and restart MongoDB.

OPTIONS = "-- auth-f $ CONFIGFILE"
/Etc/init. d/mongod restart

Log on and perform user authentication

Use admin
Db. auth ("yourusername", "password ")

You can also log on

Mongo -- port 27017-u yourusername-p password -- authenticationDatabase admin

After the authentication is successful, create a common user and use this user to log on to the specified database.

Db. createUser (
User: "123 ",
Pwd: "123123 ",
Roles :[
{Role: "readWrite", db: "firstdb"}, # read/write permission granted to the firstdb database
{Role: "read", db: "products"}, # read permission for the products database

Use PyMongo to connect to a user-authenticated mongodb instance

From pymongo import MongoClient
Dedicated client ('mongodb: // user: '+ 'password' +' @ ')

If the password contains symbols such as %, \,/, you must use urllib for escape.

Import urllib
From pymongo import MongoClient
Password = urllib. quote_plus ('pass/word % &\/')
MongoClient ('mongodb: // user: '+ password +' @ ')

Change the password of a specified user

Use admin
Db. changeUserPassword ("username", "newpassword ")

Delete a specified user

Use admin
Db. db. system. users. remove ({user: "username "})
