Step 6: Secure Your MongoDB Installation on Rocky Linux 9

By default, MongoDB doesn’t require authentication. However, for better security, it’s advisable to enable authentication. Start by creating an admin user with the required privileges:

Create the Admin User

To create an admin user in MongoDB on Rocky Linux 9, you can follow these steps:

In the MongoDB shell, switch to the built-in admin database, which is typically used for administrative tasks, Then, you can create the admin user. Replace adminUser and adminPassword with your desired username and password for the admin user:

test> use admin
switched to db admin

admin> db.createUser({ user: "mongo-admin", pwd: "m0ngO4dm1n2023", roles: [{role: "root", db: "admin"}]})
{ ok: 1 }

admin> db.system.users.find()
[
  {
    _id: 'admin.mongo-admin',
    userId: new UUID("af967ad4-9d24-4617-9615-80e793b6b5c1"),
    user: 'mongo-admin',
    db: 'admin',
    credentials: {
      'SCRAM-SHA-1': {
        iterationCount: 10000,
        salt: 'I0esBbduvM8pmHQ2fp2leg==',
        storedKey: 'KQb8b3TSF6py6O75FAwSO3mFZ7w=',
        serverKey: 'kPqwkvgHRsqIjgZ+c2Hl4FhpBis='
      },
      'SCRAM-SHA-256': {
        iterationCount: 15000,
        salt: '8rEzL0MdSZ2WABlcUTDchV3kt2x48epC+IHtKQ==',
        storedKey: 'FrryrJLaIABb7PEebk2zYSfUQa/P9ATkyEWP+TgPZQo=',
        serverKey: 'JLFgZVMZdLUt4zKXdjswysoLkSKlqEAFWc1SvqNJvyQ='
      }
    },
    roles: [ { role: 'root', db: 'admin' } ]
  }
]

Afterward, create a user named "mongo-admin” – feel free to modify this name as per your preference. Once you’ve added the provided script, it’s crucial to set up a password for this user.

Add Database and User MongoDB

To add database and user MongoDB, execute the following commands:

Create Database

admin> use sammlinux_db
switched to db sammlinux_db

Add User Read Wirite (R/W)

sammlinux_db> db.createUser({ user: "samm-rw", pwd: "s4mm&2023", roles: [{role: "readWrite", db: "sammlinux_db"}]})

Add User Read Only (R/O)

sammlinux_db> db.createUser({ user: "samm-ro", pwd: "s4mm#2023", roles: [{role: "read", db: "sammlinux_db"}]})

Enabling Authentication

MongoDB 6.0 configuration files are stored in the /etc/mongod.conf directory. Here, you can customize settings such as enabling Authentication and specifying the listening IP address and port to suit your needs. To enable authentication, you can use your preferred text editor to edit the MongoDB configuration file. Let’s proceed with making these changes:

[samm@mongodb ~]$ sudo vi /etc/mongod.conf

Add the following lines:

net:
  port: 27017
  bindIp: 127.0.0.1,172.32.1.80

security:
  authorization: enabled

Then restart your mongoDB service, using this command:

[samm@mongodb ~]$ sudo systemctl restart mongod

Step 7: Access MongoDB with Authentication.

At this point, it’s necessary for clients to provide authentication to gain access to the database. To confirm that MongoDB is correctly installed and operational, you can connect to the MongoDB shell. Here’s the syntax for authentication:

[samm@mongodb ~]$ mongosh 127.0.0.1:27017 -u "mongo-admin" -p --authenticationDatabase "admin"
Enter password: m0ngO4dm1n2023

When you want to access MongoDB from a client, you can do so by using the server’s IP address followed by a colon:

[samm@mongodb ~]$ mongosh 172.32.1.80:27017 -u "mongo-admin" -p --authenticationDatabase "admin"
Enter password: m0ngO4dm1n2023

Enter the password when prompted. You should now be connected to the MongoDB shell.

Current Mongosh Log ID: 63955de17d5b6ddaa159e24e
Connecting to:      mongodb://<credentials>@172.32.1.80:27017/?directConnection=true&authSource=sammlinux_db&appName=mongosh+1.6.2
Using MongoDB:      6.0.5
Using Mongosh:      1.6.2

For more information and documentation about mongosh, you can visit: https://docs.mongodb.com/mongodb-shell/

In MongoDB 6, you can use the show dbs command to display a list of available databases. Open the MongoDB shell and run the following command:

test> show dbs
sammlinux_db  40.00 KiB
test> 

This will list all the databases present on your MongoDB server, along with their sizes. Keep in mind that databases with no data may not appear in this list until they have some data stored in them.

Step 8: Change MongoDB on Rocky Linux 9 default Path (optional)

By default, MongoDB on your Rocky Linux 9 stores its data in the directory located at /var/lib/mongo. However, this directory can be altered as below.

Stop the MongoDB service.

To stop MongoDB on Rocky Linux, you can use the systemctl Here’s how you can do it:

[samm@mongodb ~]$ sudo systemctl stop mongod

Create a new directory for MongoDB data.

Now, you can create it, for example : /database/mongodb directory. and set the appropriate permissions for the directory to allow MongoDB to write data to it:

[samm@mongodb ~]$ sudo mkdir -p /database/mongodb
[samm@mongodb ~]$ sudo mkdir -p /database/mongodb/data
[samm@mongodb ~]$ sudo mkdir -p /database/mongodb/log
[samm@mongodb ~]$ sudo chown mongodb.mongodb -R /database/mongodb

Copy contents to the new directory.

If you’ve stored data in the default data location and wish to retain it, it’s crucial to move it to the new spot. For instance, if your data was previously in /var/lib/mongo, and you want to shift it to the new location, /database/mongodb, you can smoothly do this using the “rsync -av” command.

[samm@mongodb ~]$ sudo rsync -av /var/lib/mongodb /database/mongodb/data

Rename the old directory for backup.

[samm@mongodb ~]$ sudo mv /var/lib/mongodb /var/lib/mongodb.bak

After making these changes, proceed to restart the MongoDB service. This step will ensure that the modifications take effect. As a result, MongoDB will begin utilizing the new directory you’ve created to store its data.

[samm@mongodb ~]$ sudo systemctl restart mongod
