The guide focuses on the following distribution versions: RHEL / CentOS 8, RHEL / CentOS 7 and older – RHEL / CentOS 6

Save this and then you can close your text editor. After that, if you want to install the latest, stable and current version of MongoDB, you need to enter the following:

# sudo yum install -y mongodb-org
