Mongodb compass rename collection9/13/2023 ![]() The user is created in the “vehicles” database. The passwordPromt() function will ask for the password when running the createUser command. Let’s create a user for the vehicles database with only read and write permissions. The createUser command allows us to create users. Add the following lines in nf file and restart the MongoDB service to reflect the changes. You have to enable the “authentication” option in the MongoDB config file to use the access control feature. MongoDB provides this functionality using users and roles, and it has built-in roles for easy access controls. One of the most important administrative tasks is to manage permission for users. View users in a database show users / db.getUsers() View collections inside a database show collections / db.getCollectionNames() You can get the existing databases, collections, roles, and users with the show command. Let us see how to view objects in a MongoDB database. mongo -port 27017 -authenticationDatabase "admin" -u "barryadmin" -p If you don’t give the password in the command, cmd will ask for it later. The authentication database is where the user details reside, which can be any database that is used to create users. If authentication is enabled in the MongoDB installation, we can specify the user details and the authentication database. Mongo –host –port –authenticationDatabase -u -p Refer to the mongo man pages or help for details information about all available options. mongo –host –port You can use this format to specify different options while connecting the database.mongo / Specify the host and database as parameters to connect to a specific database.mongo Run this command in the localhost shell to connect to the local database on the default port 27017.You can use the mongo command to connect with a MongoDB database and use parameters like host and port if needed. Commands for connecting to MongoDBįirst, we need to know how to connect to a MongoDB database. That’s where administrative commands come in-let’s take a look. Like any database, MongoDB needs administration. Let’s take a quick look at how traditional RDBMS terminology relates to MongoDB structure.īy default, MongoDB auto-generates a 12-byte hexadecimal number for each document. MongoDB Documents are based on key-value pairs. Therefore different documents in the same collection can have different fields. Collections are created within a database and do not enforce a schema like a traditional database. The database is a physical container for collections with a dedicated file structure in the system.Ī Collection contains a group of MongoDB documents. A single MongoDB instance can contain multiple databases.Collections and documents are analogous to the traditional table and rows in an RDBMS database.MongoDB relies on concepts like Documents, Collections, and Databases: MongoDB is a high performance, highly scalable cross-platform NoSQL database. Use the right-hand menu to navigate.) MongoDB overview (This article is part of our MongoDB Guide. Viewing databases, collections, roles & users.Then, I’ll show you how to carry out a variety of basic administrative functions, with commands for: We’ll first get familiar with the basic concepts of MongoDB. This article discusses the most useful commands for MongoDB database administration.
