Mongo from start to installation and problems encountered

problem 1. To build database

use  xxx

When there is xxx When I was in the library , Do not create a new , When there is no xxx When , Automatically create xxx database

use book

The new data

db.book.insert({"name":"cjn","age":24,"sex":" male "});

When performing , error

here

MongoDB When operating , appear

db.dropDatabase()

{

"ok" : 0,

"errmsg" : "not authorized on runoob to execute command { dropDatabase: 1.0, writeConcern: { w: \"majority\", wtimeout: 600000.0 }, lsid: { id: UUID(\"24c2cedc-ec83-4d78-88f3-0d10fa35ce9d\") }, $db: \"runoob\" }",

"code" : 13,

"codeName" : "Unauthorized"

}

This tip

No permissions , Then add users quickly

Switch to admin library

use admin;

Add users
 

db.createUser( {
    user: "sa",
    pwd: "sa",
    roles: [ { role: "root", db: "admin" } ]
  });

Now that you have added users

use sa To login

db.auth('sa','sa');

And then in

db.book.insert({"name":"cjn","age":24,"sex":" male "});

success ！

 use runoob
switched to db runoob
> db.dropDatabase()
{
	"ok" : 0,
	"errmsg" : "not authorized on runoob to execute command { dropDatabase: 1.0, writeConcern: { w: \"majority\", wtimeout: 600000.0 }, lsid: { id: UUID(\"24c2cedc-ec83-4d78-88f3-0d10fa35ce9d\") }, $db: \"runoob\" }",
