MongoDB User Management

Create a Super User

Use Admindb.createuser (  {    "Adminusername",    "UserPassword",    roles:    [      {        "useradminanydatabase",        "admin"      }    ]  })

There are two types of superuser role, useradmin or useradminanydatabase (more access to all databases than the previous one).

DB is the name of the specified database, and admin is the management database.

Log in with the newly created user

MONGO--host xxx-u adminusername-p userpassword--authenticationdatabase Admin

View permissions for the current user

Db.runcommand (  {    usersinfo:"UserName",    showprivileges:true  }) 

Create a general user, also with CreateUser

Use Db01db.createuser (  {    User:"oneuser",    pwd:"12345",    roles:[      { Role:"read", DB: "Db01"},      {role:"read", DB: "DB02"},      {role:"read", DB: "DB03" }    ]  })

Create a superuser who is not restricted by access

Use Admindb.createuser (  {    User:"superuser",    pwd:"pwd",    roles:["root" ]  })

Change Password

Use Admindb.changeuserpassword ("username", "xxx")

View user Information

Db.runcommand ({usersinfo: "UserName"})

Modify password and user information

Db.runcommand (  {    updateUser:"username",    pwd:"xxx",    customdata:{ Title:"xxx"}  })

Attention:

1. and user management related operations are basically to run under the Admin database, to use the admin first;

2. If under a single database, it can only operate on the permissions of the current database.
