This article is to share with you about how to achieve user management in MongoDB, the editor thinks it is very practical, so I share it with you to learn. I hope you can get something after reading this article.

● condition 1: turn on authorization authentication when the server starts.

● condition 2: you need to configure a user name and password.

To be clear, however, if you want to configure a user name and password, it must be for a database. For example, if you are creating a stone database user, you must switch to the stone database.

Example: perform the creation of a user

Any user must have their own operational roles: read, readWrite

> use admin

Switched to db admin

> db.createUser ({

... "user": "root"

... "pwd": "root"

... "roles": [{"role": "root", "db": "admin"}]

.)

Successfully added user: {

"user": "root"

"roles": [

{

"role": "root"

"db": "admin"

}

]

}

> use hr

Switched to db hr

> use hr

Switched to db hr

> db.createUser ({

... "user": "stone"

... "pwd": "stone"

... "roles": [{"role": "readWrite", "db": "hr"}]

.)

Successfully added user: {

"user": "stone"

"roles": [

{

"role": "readWrite"

"db": "hr"

}

]

}

So now it means that the stone user has been successfully created. Then if you want the secondary user name to work, you must open the MongoDB service in an authorized manner. Modify the parameter file of MongoDB.

Example: modify the parameter file to add authorization startup

[root@D2-LZY245 ~] # vim / usr/local/mongodb/mongodb.conf

Dbpath=/usr/local/mongodb/db

Logpath=/usr/local/mongodb/log/mongodb.log

Logappend=true

Auth=true

Port=27017

Fork=true

Restart the database:

> use admin

Switched to db admin

> db.shutdownServer ()

[root@D2-LZY245] # mongod-f / usr/local/mongodb/mongodb.conf

About to fork child process, waiting until server is ready for connections.

Forked process: 25987

Child process started successfully, parent exiting

[root@D2-LZY245 ~] # mongo

MongoDB shell version v3.4.7

Connecting to: mongodb://127.0.0.1:27017

MongoDB server version: 3.4.7

> use stone

Switched to db stone

> db.emp.find ()

Error: error: {

"ok": 0

"errmsg": "not authorized on stone to execute command {find:\" emp\ ", filter: {}}"

"code": 13

"codeName": "Unauthorized"

}

At this time, an authentication startup mode is added, and it is found that you can still log in without entering a user name and password, and you can also switch the database directly. However, an error occurred when using the database collection.

Example: use a user name and password when logging in to the database

[root@D2-LZY245] # mongo-u "stone"-p "stone"-authenticationDatabase "hr"

MongoDB shell version v3.4.7

Connecting to: mongodb://127.0.0.1:27017

MongoDB server version: 3.4.7

Or:

[root@D2-LZY245 ~] # mongo

MongoDB shell version v3.4.7

Connecting to: mongodb://127.0.0.1:27017

MongoDB server version: 3.4.7

> use hr

Switched to db hr

> db.auth ("stone", "stone")

one

At this point, it means that the login operation of the user has been successfully implemented.

Example: change password

[root@D2-LZY245] # mongo-u root-p 'root'-- authenticationDatabase' admin'

> db.changeUserPassword ("stone", "stone")

Example: view users and roles

> use admin

Switched to db admin

> db.system.users.find ()

{"_ id": "test.stone", "user": "stone", "db": "test", "credentials": {"SCRAM-SHA-1": {"iterationCount": 10000, "salt": "boSLJ2acqh503AW0MZO7yA==", "storedKey": "Y7zaryoqOieKsVs61SrAMAK8c =", "serverKey": "+ wa0fO2hwNrLRIuVmtJMvR1AJv0="}, "roles": [{"role": "readWrite" "db": "hr"}]}

{"_ id": "admin.root", "user": "root", "db": "admin", "credentials": {"SCRAM-SHA-1": {"iterationCount": 10000, "salt": "NmiMDfzuCnkO1CRKrVUV9A==", "storedKey": "rD6NaqsfON8h0YMNv6idPKUpac0=", "serverKey": "9MXDynhFSNmHEkMIMfxnSKdQPio="}, "roles": [{"role": "root" "db": "admin"}]}

{"_ id": "hr.stone", "user": "stone", "db": "hr", "credentials": {"SCRAM-SHA-1": {"iterationCount": 10000, "salt": "69NLL2oWTg0OehrBwytbswung =", "storedKey": "LRmPZjHZorxhfWA+RS6SgzLbev4=", "serverKey": "59xkCl7qKKroomHrKrlK5QMdGx94U8 ="}}, "roles": [{"role": "readWrite" "db": "hr"}]}
