I am trying to add authorization to my MongoDB.
I am doing all this on Linux with MongoDB 2.6.1.
My mongod.conf file is in the old compatibility format
(this is how it came with the installation).
1) I created admin user as described here in (3)
http://docs.mongodb.org/manual/tutorial/add-user-administrator/
2) I then edited mongod.conf by uncommenting this line
auth = true
3) Finally I rebooted the mongod service and I tried to login with:
/usr/bin/mongo localhost:27017/admin -u sa -p pwd
4) I can connect but it says this upon connect.
MongoDB shell version: 2.6.1
connecting to: localhost:27017/admin
Welcome to the MongoDB shell!
The current date/time is: Thu May 29 2014 17:47:16 GMT-0400 (EDT)
Error while trying to show server startup warnings: not authorized on admin to execute command { getLog: "startupWarnings" }
5) Now it seems this sa
user I created has no permissions at all.
root@test02:~# mc

What is the problem? I repeated this whole procedure 3 times and
I think I did it all as specified in the MongoDB docs. But it doesn't work.
I was expecting this sa
user to be authorized to do anything so that
he can then create other users and give them more specific permissions.
Update mongod.conf file
vi /etc/mongod.conf
net:
port: 27017
bindIp: 0.0.0.0
security:
authorization: enabled
Start MongoDB service demon
systemctl start mongod
Open MongoDB shell
mongo
Execute this command on the shell
use admin
db.createUser(
{
user: 'admin',
pwd: 'YouPassforUser',
roles: [ { role: 'root', db: 'admin' } ]
}
);
Remote root user has been created. Now you can test this database connection by using any MongoDB GUI tool from your dev machine. Like Robo 3T
This may be because you havent set noAuth=true in mongodb.conf
# Turn on/off security. Off is currently the default
noauth = true
#auth = true
After setting this restart the service using
service mongod restart
In addition, notice that if your mongo shell client fails to connect correctly to the mongod
instance, you can receive such "Permission Denied" errors.
Make sure that your client opens a connection by checking the connection port, but also that the port you are using in mongod
is not in use. You can set a different port by using the --port <port>
parameter in both the shell and the process.
I came across this thread with a similar issue, but my problem was that I used the collection name instead of the database name.
It's a simple question.
use yourDB
show users
db.createUser( { user: "yourUser", pwd: "password", roles: [ "readWrite", "dbAdmin" ] } )
or
db.grantRolesToUser('yourUser',[{ role: "dbAdmin", db: "yourDB" }])
Use Admin :
use admin
Create a super user :
db.createUser(
{
user: "master",
pwd: "test@123",
roles: [
{
role: "readWriteAnyDatabase",
db: "admin"
},
{
"role" : "dbAdminAnyDatabase",
"db" : "admin"
},
{
"role" : "clusterAdmin",
"db" : "admin"
},
"userAdminAnyDatabase"
]
}
)
I had this problem because of the hostname in my MongoDB Compass was pointing to admin instead for my project. Fixed by adding the /projectname after the hostname :) Try this:
Use the same connection string in your code too:
Good luck.
use mydb
db.createUser( { user: "test", pwd: "secret", roles: [ "readWrite", "dbAdmin"],passwordDigestor:"server" } )
Perhaps a quick example of how to change a current user will be helpful to somebody. This is what I was actually looking for.
Following advice of @JohnPetrone I added readWrite role to my admin user with grantRolesToUser
> use admin
> db.grantRolesToUser("admin",["readWrite"])
> show collections
system.users
system.version
You can try: Using the --authenticationDatabase flag helps.
mongo --port 27017 -u "admin" -p "password" --authenticationDatabase "admin"
I had a similar problem here on a Windows environment: I have installed Bitnami DreamFactory and it also installs another MongoDb that is started on system boot. I was running my MongoDbService (that was started without any error) but I noticed after losing a lot of time that I was in fact connecting on Bitnami's MongoDb Service. Please, take a look if there is not another instance of mongoDB running on your server.
Good Luck!
It's a bit confusing - I believe you will need to grant yourself readWrite to query a database. A user with dbadmin or useradmin can admin the database (including granting yourself additional rights) but cannot perform queries or write data.
so grant yourself readWrite and you should be fine -
http://docs.mongodb.org/manual/reference/built-in-roles/#readWrite
Agreed that you've to get authenticated to admin db and needs at least a role with correct privileges which would avoid 'local host exception' from DB(this is for mongoDB's hosted on-premises), though you've everything in place & still getting not authorized exceptions on almost every command, while accessing mongoDB which got created using Mongo Atlas, then here is the place where you might know the reason, why :
and also check this if you've hosted mongoDB on mongo Atlas:
For MongoDB shell version v4.2.8 I've tried different ways to back-up my database with auth, my winner solution is
mongodump -h <your_hostname> -d <your_db_name> -u <your_db_username> -p <your_db_password> --authenticationDatabase admin -o /path/to/where/i/want
I know this answer is coming really late on in this thread but I hope you check it out.
The reason you get that error is based on the specific role that you granted to the user, which you have gathered by now, and yes giving that user the role root
will solve your problem but you must first understand what these roles do exactly before granting them to users.
In tutorial you granted the user the userAdminAnyDatabase
role which basically give the user the ability to manage users of all your databases.
What you were trying to do with your user was outside its role definition.
The root
role has this role included in it definition as well as the readWriteAnyDatabase
, dbAdminAnyDatabase
and other roles making it a superuser (basically because you can do anything with it).
You can check out the role definitions to see which roles you will need to give you users to complete certain tasks. https://docs.mongodb.com/manual/reference/built-in-roles/ Its not advisable to make all your users super ones :)
