Similarly you might divvy out access other databases or other users or both. Mongo # fire up the mongo client on the system with MongoDB installedÄb.addUser( )Īnd you now have a user mydbuser with only access rights to the database mydb. Create burgers database user with name bob and password 12345. Lines prefixed by # are comments and should be no-ops in a shell if you copy paste but I havenât tested every shell. The steps below assume a vanilla install of Mongodb that can be accessed without auth over the loopback interface(127.0.0.1). Instead I opted to use a single set of user accounts that have access to all the databases (so that password updates etc. db.createRole(role, writeConcern) role Information and permissions regarding the role. We can also inherit privileges from a different role in the new roles. We can create an independent role within MongoDB by expressing permissions on all privileges explicitly. I could have chosen to create user accounts per database (relatively easy to setup) but that can be a chore to maintain. The readWrite role in the product database. ex: mongo mongo01test -u admin -p adminpaaswrod. mongo -u -p .Create user accounts to read-write and administer the databases. if the Access control is enabled on the MongoDB deployment, Then you should login by authenticating to the relevant database with admin user (or user with userAdmin role) which you want to control the access. Not sure if there is a way to create a global Role to maintain HR & AP at the same time. The show roles command above will show you Roles for each DB. Enable authentication for the MongoDB instance.Ä¢. Lets say we have 2 Mongo DBs: HR & AP, I would need to switch between the DBs to grant roles accordingly. This translates into the following requirements (among others)Ä¡. I use MongooseJS to access the MongoDB server. My app has 6 databases (relatively small) and the NodeJS server runs on a different EC2 instance and accesses the databases over the network. I wonât go into too many details about the mechanics of setting up EC2 instances and installing Mongo here though. While working through this, I didnât find any examples for syntax of the end to end scenario and in fact had to resort to some brute force trial and error â hopefully this post will remedy some of that. Among other things, I needed to set up authentication and this post is about what I learned. Recently, I decided to move the MongoDB backend to an Amazon EC2 instance.
