Install MongoDB on AlmaLinux 8 [Step-by-Step]


MongoDB is a cross-platform, open-source, and document-based database management system. It facilitates users by providing full index support, high availability, replication, and auto-sharding, etc. As we mentioned earlier, MongoDB is a cross-platform database. However, the data integration process is much easier and comparatively faster than other databases. Due to the free availability of the MongoDB database, it is used in many organizations.

We will go through in this guide how to install MongoDB on AlmaLinux 8 system.


Lab Environment

To install MongoDB on AlmaLinux 8.4, we will set up the following environment:

Server OS: AlmaLinux release 8.4
MongoDB version: 4.4.10
Server IP:

Client IP:
Client OS: Ubuntu 20.04


Steps to install MongoDB on AlmaLinux 8

You can install MongoDB on AlmaLinux 8 distribution by executing the following steps:


Step 1: Update the system packages list (Optional)

This step can be considered optional and you may choose to skip. Here we prefer to update all the packages of our server before we install mongodb on AlmaLinux 8.

Open the terminal from the left sidebar of the system tray. Update the all system packages list by running the following ‘dnf’ command:

$ sudo dnf update

This step is recommended for installing a new package on your Linux system but, if you have already updated packages then, skip this step.


Step 2: Create MongoDB repository

MongoDB can not be directly installed on AlmaLinux 8 by using the system default repository. Create a file repository using the nano text editor to include the MongoDB official repository in your system. To create MongoDB repo, use the following command:

$ sudo nano /etc/yum.repos.d/mongodb.repo

Paste the following content in this repository file:

name=MongoDB Repository

mongodb repository file content

To  check that the MongoDB repository has been added to your system, use the following 'repolist' command:

$ sudo dnf repolist

yum repolist

Once the MongoDB repository is configured on the AlmaLInux 8 system, move towards the installation step.


Step 3: Install MongoDB on AlmaLinux 8

Install the latest stable version of MongoDB on AlmaLinux 8 system by using the below-mentioned command:

$ sudo dnf install mongodb-org mongosh

Here mongodb-org will install all the packages required to configure mongodb as a server and mongosh is used as a client tool to connect to mongodb instance: During the installation, it will import the gpg or signing key for MongoDB to your system.

If you wish to install specific version of mongodb then you can specify the MongoDB version with dnf on your AlmaLinux distribution using the following command:

$ sudo dnf 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


Now, to prevent unattended upgrades with the upgrade of yum, pin the package by adding this package in the exclude directive '/etc/yum.conf'  using the following commands:

$ sudo cat >> /etc/yum.conf << EOF
> exclude=mongodb-org,mongodb-org-database,mongodb-org-server,mongodb-org-shell,mongodb-org-mongos,mongodb-org-tools

exclude yum.repo directive


Step 4: Enable MongoDB service

Once the installation of MongoDB is completed, start and enable service of MongoDB by using the following 'systemctl' command:

$ sudo systemctl start mongod
$ sudo systemctl enable mongod

start and enable mongodb service

After enabling the service, check the running status of mongod service by using the below-mentioned command:

$ sudo systemctl status mongod

check running status mongodb service


Step 5: Access MongoDB shell

You can access the MongoDB shell by running the below-mentioned terminal command:

$ mongo

The following shell interface displays on the terminal where you can run the database queries:

start mongodb

Connect with the admin database to create a new user with administrative privileges to manage the database.

> use admin

login with admin database

Now, create a new user and assigned role, name, and password by running the below-given command:

> db.createUser(
     user: "Sam ",
     pwd: "sam123",
     roles: [ { role: "userAdminAnyDatabase", db: "admin" } ]

Press ‘Enter’ to execute the above database query. You will receive the following output on the terminal screen:

create database user on mongodb

Use the following command to display all database users including the newly created user on your system.

> show users

show mongodb users

You can connect to the MongoDB shell instance within the localhost using the default port '27017'.

$ mongosh "mongodb://localhost:27017"

mongosh localhost-27017


Step 6: Enable Remote connections

To enable access to the remote connection, you need to add client IP in the configuration file as follows:

$ sudo nano /etc/mongod.conf

Search the following lines:

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

Change the preceding section into the following form:

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


Step 7: Firewall configurations

To configure the firewall setting for the 28015 port, use the following commands:

$ sudo firewall-cmd --permanent --add-port=27017/tcp 
$ sudo firewall-cmd --reload


Step 8: SELinux configurations

Check your SELinux policy on the server using the following command:

~]# getenforce

If it is Enforcing or Permissive then you can apply the following SELinux rule. If SELinux is disabled then you can skip this step.

To configure the SELinux for MongoDB port, run the below-mentioned command:

$ sudo semanage port -a -t mongod_port_t -p tcp 27017


Step 9: Access mongodb server from client node

Next we will use Ubuntu client to connect to our mongodb server. You can follow the official guide to install mongodb related packages on Ubuntu to setup your environment.

Next verify the connectivity towards mondodb server from the client using mongosh as follows:

$ sudo mongosh "mongodb://"

Install MongoDB on AlmaLinux 8 [Step-by-Step]

Finally, we have completed the whole process to install MongoDB on AlmaLinux 8 distribution.


Uninstall MongoDB from AlmaLinux 8

First, stop and disable the mongod service by running the following commands:

$ sudo systemctl disable mongod
$ sudo systemctl stop mongod

Now, execute the following command to uninstall the MongoDB from your AlmaLinux system:

$ sudo dnf erase $(rpm -qa | grep mongodb-org)

uninstall mongodb

The above command will uninstall all MongoDB packages from your system. To remove all databases and log files of MongoDB, issue the following command:

$ sudo rm -r /var/log/mongodb
$ sudo rm -r /var/lib/mongo

remove mongodb log files



We presented in this article how to install MongoDB database applications on the AlmaLinux 8 distribution. We also explained how to start a service and create a new database user with administrative privileges. In the end, we also mentioned the uninstallation process of MongoDB.
