Step 2. Install MongoDB on Ubuntu system.
Import the repository’s GPG key and add the MongoDB repository with:
1 2 | wget-qO-https://www.mongodb.org/static/pgp/server-4.4.asc | sudo apt-key add - sudoadd-apt-repository'deb [arch=amd64] https://repo.mongodb.org/apt/ubuntu focal/mongodb-org/4.4 multiverse' |
After that the repository is enabled, install the MongoDB using the apt command:
1 | sudoaptinstallmongodb-org |
Once the installation is completed, start the MongoDB daemon and enable it to start on boot by typing:
1 2 | sudosystemctlstartmongod sudosystemctlenablemongod |
Confirm the version of the MongoDB server:
1 | mongod--version |
Step 3. Configuring MongoDB.
The MongoDB configuration file is named mongod.conf.
1 | sudonano/etc/mongod.conf |
1 2 | security: authorization:enabled |
The authorization the option enables Role-Based Access Control (RBAC) that regulates users access to database resources and operations. If this option is disabled each user will have access to all databases and perform any action.
After editing the MongoDB configuration file, restart the mongod service for changes to take effect:
1 | sudosystemctlrestartmongod |
Step 4. Create Admin User
By default, MongoDB doesn’t authenticate users to read and modify data, and it is the biggest security concern. To enable authentication, first, create a database administrative user.
