In this MongoDB tutorial we are going to see how to install NoSQL Database MongoDB on CentOS 7.

MongoDB is not available from the official CentOS 7 software repository, But MongoDB provides a yum repository for CentOS 7 which we use to install the latest version of MongoDB on CentOS 7.

Following are the steps you need to follow.

  1. Add MongoDB repository for CentOS 7.
  2. Install MongoDB with yum install command.
  3. Start mongod service with systemctl command.

Add MongoDB repository for CentOS 7

Let's start with creating the yum repository for MongoDB Database Server.

Create yum repo file:

touch /etc/yum.repos.d/mongodb-org-3.4.repo

Then, open the mongodb-org-3.4.repo file with your preferred text editor and add following entries.

[mongodb-org-3.4]
name=MongoDB Repository
baseurl=https://repo.mongodb.org/yum/redhat/$releasever/mongodb-org/3.4/x86_64/
gpgcheck=1
enabled=1
gpgkey=https://www.mongodb.org/static/pgp/server-3.4.asc

Run the yum repolist command and make sure mongodb repository is active.

Now the repository is set, We can install mongodb with yum install command:

sudo yum -y install mongodb-org

The mongodb-org package also includes following core packages, mongodb-org-server, mongodb-org-shell and mongodb-org-tools.
