Install MongoDB on Rocky Linux 8.4 (Step-by-Step)

Written by - Deepak Prasad

In this tutorial we will cover the steps to install MongoDB on Rocky Linux.


Introduction on MongoDB

  • MongoDB is a document-oriented database, not a relational one.
  • The primary reason for moving away from the relational model is to make scaling out easier, but there are some other advantages as well. A document-oriented database replaces the concept of a “row” with a more flexible model, the “document.”
  • By allowing embedded documents and arrays, the document-oriented approach makes it possible to represent complex hierarchical relationships with a single record. This fits naturally into the way developers in modern object-oriented languages think about their data.
  • MongoDB is a general-purpose database, so aside from creating, reading, updating, and deleting data, it provides most of the features you would expect from a database management system and many others that set it apart.
  • Performance is a driving objective for MongoDB, and has shaped much of its design. It uses opportunistic locking in its WiredTiger storage engine to maximize concurrency and throughput. It uses as much RAM as it can as its cache and attempts to automatically choose the correct indexes for queries.


Lab environment

I have created two separate Virtual Machines running on Oracle Virtual Box. One of these VMs will act as a Server while the other will act as a Client.

OS: Rocky Linux release 8.4 (Green Obsidian)
Kernel: 4.18.0-305.10.2.el8_4.x86_64
MongoDB Version: 5.0
Server's IP Address:
Client's IP Address:


Step 1: Create the repository

Create a mongoDB repository file:

[root@rockylinux ~]# vim /etc/yum.repos.d/mongodb-org-5.0.repo

In the above, file copy and paste the below content and save.

name=MongoDB Repository

Update the repository:

[root@rockylinux ~]# yum update -y

In your repository list, you can now see the new mongoDB repo:

[root@rockylinux ~]# yum repolist

Step 2: Install MongoDB packages

To install the latest stable release of MongoDB, run the following command:

[root@rockylinux ~]# yum install -y mongodb-org

Alternatively, to install a specific release of MongoDB, specify the version number for each packages:

[root@rockylinux ~]# yum install -y mongodb-org-5.0.1 mongodb-org-database-5.0.1 mongodb-org-server-5.0.1 mongodb-org-shell-5.0.1 mongodb-org-mongos-5.0.1 mongodb-org-tools-5.0.1

To prevent the unintended upgrades with the upgrade of yum, we need to pin the package. To pin, Add the following package in exclude directive to /etc/yum.conf:

[root@rockylinux ~]# cat >> /etc/yum.conf << EOF

[root@rockylinux ~]# For pin these package:


By default, MongoDB runs using the mongod user account and uses the following default directories,

/var/lib/mongo (the data directory)
/var/log/mongodb (the log directory)

And the below configuation file.


You can see the any find of changes, error, important message in /var/log/mongodb/mongod.log file.


Step 3: Run MongoDB Instance

To Start MongoDB service:

[root@rockylinux ~]# systemctl start mongod

Verify that MongoDB has started successfully:

[root@rockylinux ~]# systemctl status mongod

You can check the output:

If you want to run MongoDB service start automatically at boot time, issue the following command:

[root@rockylinux ~]# systemctl enable mongod


Step 4: Connecting to MongoDB instance

Within the localhost and default port 27017, you can run the mongosh command line tool, the MongoDB shell, to connect the instance:

[root@rockylinux ~]# mongosh

This is similar to:

[root@rockylinux ~]# mongosh "mongodb://localhost:27017"

The output will be like that:

Step 5: Enable Remote connection

By default, MongoDB is not allowed any remote connection. To enable it add associative remote clients IP as bindIP in the /etc/mongod.conf file:

[root@rockylinux ~]# vim /etc/mongod.conf

Find the below section:

# network interfaces
port: 27017
bindIp: # Enter,:: to bind to all IPv4 and IPv6 addresses or, alternatively, use the net.bindIpAll setting.

And turned it into the following section:

# network interfaces
port: 27017
bindIp:, # Enter,:: to bind to all IPv4 and IPv6 addresses or, alternatively, use the net.bindIpAll setting.

Here, is the IP address of MongoDB Server. Restart the service to take the effect:

[root@rockylinux ~]# systemctl restart mongod

Now check the remote connection from the client node:

[root@rockylinux ~]# mongosh "mongodb://"


Bind mongodb instance on a non-default port

You may choose to use a different port number for your mongodb instance. We will change the default port number form 27017 to 28015 (or any other as needed):

[root@rockylinux ~]# vim /etc/mongod.conf

[root@rockylinux ~]# network interfaces
port: 27017

Change the upper section into the below one:

[root@rockylinux ~]# network interfaces
port: 28015

Restart the service to activate the changes:

[root@rockylinux ~]# systemctl restart mongod


Step 6: Configure Firewall

Next we will allow the port to firewall, since we are using firewalld in our Rocky Linux setup so we will use the same to allow port 28015:

[root@rockylinux ~]# firewall-cmd --permanent --add-port=28015/tcp 
[root@rockylinux ~]# firewall-cmd --reload


Step 7: Configure SELinux

Next we will also allow mongodb port on the SELinux

[root@rockylinux ~]# semanage port -a -t mongod_port_t -p tcp 28015

Check the connection from the client node:

[root@rockylinux ~]# mongosh "mongodb://"


Step 8: Uninstall MongoDB

This process will completely remove the MongoDB packages, the configuration files, the data directory and the log directory. So, before perform this step please backup all of your data.

Stop the mongodb process by issuing the following command:

[root@rockylinux ~]# systemctl disable mongod
[root@rockylinux ~]# systemctl stop mongod

Remove Packages:

[root@rockylinux ~]# yum erase $(rpm -qa | grep mongodb-org)

Remove Data Directories:

[root@rockylinux ~]# rm -r /var/log/mongodb
[root@rockylinux ~]# rm -r /var/lib/mongo



In this tutorial, we learned how to obtain the MongoDB software. We also discussed the version numbers, how to install and run MongoDB, and how to install and run its prerequisites on Rocky Linux. Next, we enabled firewall and SELinux to establish a connection to a database.
