MongoDB 3.2 - creating a CRUD admin for a certain database - mongodb

Question

I'm trying to create a CRUD database administrator.
From what I read from official documentation, there is a role readWrite, but I don't really got the process of creating an admin.
So I ran mongod without --auth and created a user with these parameters:
use myCustomDB
db.createUser({
user: "snoop",
pwd:"stickyickyicky",
roles:[{role:"readWrite", db:"myCustomDB"}]
});
The command line answered Successfully added new user blah blah..
but when I authenticate it returns 1, which, I suppose is true. But when I run command for example db.peops.find() it gives me this Error: error: { "$err" : "not authorized for query on myCustomDB.peops", "co de" : 13 }

It may be your find call. Try formatting like this:
db.getCollection('peops').find({})
If that's not it, it might be your auth schema. This may not be the best method, but I thought I would share the steps I take to setup a super admin and database specific admin, and a read only user. The all caps should be replaced with corresponding credential / db name:
1.Change Mongo Security Method
sudo service mongod start
mongo
use admin
db.system.version.remove({})
db.system.version.insert({ "_id" : "authSchema", "currentVersion" : 3 })
2.Create Super Admin User
use admin
db.createUser( { user: "SUPERADMINUSER", pwd: "SUPERADMINPASS", roles: [ { role: "userAdminAnyDatabase", db: "admin" } ] } )
3.Create db Admin with read/write access
use DATABASE
db.createUser( { user: "DBADMIN", pwd: "DBPASSWORD", roles: [ { role: "userAdmin", db: "DATABASE" }, { role: "readWrite", db: "DATABASE" }] } )
db.createUser( { user: "DBREADONLYUSER", pwd: "DBREADONLYPASS", roles: [ { role: "read", db: "DATABASE" }] } )
4.Edit mongod.config in /etc folder
sudo service mongod stop
in mongod.config edit so that auth = true is not commented out.
5. Restart mongo, security in place
sudo service mongod start
***Troubleshooting: If you are running mongo 3.2 you can likely skip the db.system.version remove and insert commands, you may want/need to upgrade to SCRAM-SHA-1, if so run db.adminCommand({authSchemaUpgrade: 1}); set up users the same way as shown above, when editing your /etc/mongod.conf file instead of auth=true comment in security: and add authorization=true as follows:
security:
authorization: enabled
