Stop the running instance of mongod
mongod --config /usr/local/etc/mongod.conf --auth
then start without --auth like
mongod --config /usr/local/etc/mongod.conf
then update your roles like
db.updateUser(“admin”,{roles :
[“userAdminAnyDatabase”,”userAdmin”,”readWrite”,”dbAdmin”,”clusterAdmin”,”readWriteAnyDatabase”,”dbAdminAnyDatabase”]});
Now again start mongod with --auth and try.
The idea is you have to create user under “admin” database with all the ROLES mentioned above.
But this user is not part of other databases. So once you created the admin user,
then login as that admin user,
SERVER: mongod –config /usr/local/etc/mongod.conf –auth
CLIENT: ./mongodb/bin/mongo localhost:27017/admin -u adminUser -p
123456
use APPLICATION_DB
again create a new user (say APP_USER) for this APPLICATION_DB. This time for this application user you need only “dbOwner” role.
db.createUser({user:"test", pwd:"test", roles:['dbOwner']})
Now your application has to use this APP_USER and APP_DB.
