MongoDB-3.6 Community Edition Installation

In this post, I am going to use yum to install MongoDB-3.6 from MongoDB’s official repository. First we start with adding a .repo file at location /etc/yum.repos.d/. You can name the file anyway you wish but the extension has to be .repo.

vim /etc/yum.repos.d/mongodb.repo

mongodb installation

Paste the follow code into the .repo file you created, save and exit. You can change 3.6 to the version you want. For instance, 3.4 or 3.2.

[mongodb-org-3.6]

baseurl=https://repo.mongodb.org/yum/redhat/$releasever/mongodb-org/3.6/x86_64/
