MongoDB adds user authentication: Add users, delete users, modify user passwords, read and write permissions, read-only permissions

1. Add and verify the user

> Use admin
> Db.adduser ("Zjx", "Tsjianxin") #添加用户

> Db.auth ("Zjx", "Tsjianxin")

These add users to the previous version of 2.6, and the 2.6 release adds the user and gives permission: View source print?

1

Use admin

2	Db.createuser ({User: "root", pwd: "Root", Roles:[{role: "ReadWrite", DB: "Admin"}]})

2. View existing users

> Db.system.users.find ()

3. Now to configure a user with read and write access to another database 51CV

> Use 51CV
> Db.adduser ("51CVRW", "51CV")
... "readOnly": false ...

4. Configure a user with read-only permissions

> Use 51CV
> Db.adduser ("51cvr", "51CV", True)
> Db.system.users.find ()
... "readOnly": True ...

5. Delete a user

> Use dbname (admin or 51CV, etc)
> Db.system.users.remove ({User: "haha"})
> Db.system.users.find ()
