How to Install MongoDB on Scientific Linux

Prerequisites

Before proceeding, ensure that your system is up to date by running the following commands:

sudo yum update
sudo yum upgrade

Next, you’ll need to install some necessary packages. If you haven’t already installed a text editor like nano or vim, follow our guides on how to install nano on Scientific Linux or how to install vim on Scientific Linux.

Installing MongoDB on Scientific Linux

Now, let’s install MongoDB on your Scientific Linux system. Follow these steps:

1. First, create a new repository file for MongoDB:

sudo nano /etc/yum.repos.d/mongodb-org.repo

2. Next, add the following repository information to the file:

[mongodb-org-4.4]
name=MongoDB Repository
baseurl=https://repo.mongodb.org/yum/redhat/$releasever/mongodb-org/4.4/x86_64/
gpgcheck=1
enabled=1
gpgkey=https://www.mongodb.org/static/pgp/server-4.4.asc

3. Save the file and exit the text editor.
4. Now, you can install MongoDB by running:

sudo yum install -y mongodb-org

MongoDB is now installed on your system.

Configuring MongoDB on Scientific Linux

Before starting MongoDB, you should configure it according to your requirements. To do this, edit the MongoDB configuration file using your preferred text editor:

sudo nano /etc/mongod.conf

In this file, you can adjust settings such as bindIp, port, dbPath, and more. For more information on configuring MongoDB, refer to the official MongoDB documentation.

After making the necessary changes, save the file and exit the text editor.

Starting and Enabling MongoDB on Scientific Linux

To start the MongoDB service, run the following command:

sudo systemctl start mongod

To ensure that MongoDB starts automatically upon system boot, enable the service:

sudo systemctl enable mongod

Testing MongoDB on Scientific Linux

Now, let’s verify that MongoDB is functioning correctly. First, check the status of the MongoDB service:

sudo systemctl status mongod

You should see an output indicating that the service is active and running.

Next, connect to the MongoDB shell by running:

mongo

You should now be connected to the MongoDB shell. Type exit to quit the MongoDB shell.

Securing MongoDB on Scientific Linux

To secure your MongoDB installation, follow these steps:

1. Connect to the MongoDB shell:

mongo

2. Switch to the admin database:

use admin

Create a new user with the appropriate role and password:

db.createUser(
   {
     user: "your_username",
     pwd: "your_password",
     roles: [ { role: "userAdminAnyDatabase", db: "admin" } ]
   }
)

Replace your_username and your_password with the desired credentials.

Enable Authentication

To enable authentication, open the MongoDB configuration file:

sudo nano /etc/mongod.conf

Add the following lines under the security section:

security:
  authorization: enabled

Save and exit the file. Now restart the MongoDB service:

sudo systemctl restart mongod

MongoDB is now installed and configured with authentication enabled.

Connect to MongoDB

To connect to MongoDB with authentication, use the following command:

mongo -u your_username -p your_password --authenticationDatabase admin

Replace your_username and your_password with the appropriate credentials.

Conclusion

Congratulations! You have successfully installed and configured MongoDB on your Scientific Linux system. You now have a powerful, scalable, and document-oriented database to use for your applications. For further information and to learn more about MongoDB, visit the official MongoDB documentation.
