MongoDB is a cross-platform program, commonly
MongoDB is one of the leading general purpose database platforms. It was designed keeping in consideration of developers and their application needs to truly unleash the power of applications that they build. The company adopted open source development model in 2009 and began offering commercial support in 2013.

This tutorial guide only supports 64-bit systems. However you can get information about various supported platforms, here.
Supported packages are included in their MonogDB repository. It contains the following packages:
- mongodb-org-server (Contains mongod daemon + configuration file )
- mongodb-org-shell (Contains mongo shell)
- mongodb-org-tools (Contains mongo backup and management tools)
- mongodb-org-mongos (Contains mongos daemon)
- mongodb-org (Will install all above components)
Method 2: Starting the Installation:
Creating repo file in /etc/yum.repos.d/ directory, like below:
$ sudo vi /etc/yum.repos.d/mongodb-org-4.0.repo
Add the following in the newly created repo file:
[mongodb-org-4.0] name=MongoDB Repository baseurl=https://repo.mongodb.org/yum/amazon/2013.03/mongodb-org/4.0/x86_64/ gpgcheck=1 enabled=1 gpgkey=https://www.mongodb.org/static/pgp/server-4.0.asc
After successfully creating the required repo file, you can begin installation and verify the installed version by the following command:
$ sudo yum install -y mongodb-org $ sudo mongod --version
Configuring MongoDB :
After installing the mongodb package, you can configure it as per your need. Configuration file location (default): ‘/etc/mongod.conf’
$ cat /etc/mongod.conf
MongoDB Default Settings:
By default, MongoDB runs through mongod user account and uses the following default directories for database storage path and logs file path.
- /var/lib/mongo (the data directory)
- /var/log/mongodb (the log directory)
Through this process the default directory paths are created as above and the owner and group for these directories are set to “mongod”.
Method 2: Install Mongo DB from tarball:
Download the MongoDB tarball package from MongoDB Download Center.
Extract the downloaded tar file.
$ sudo tar -zxvf mongodb-linux-x86_64-amazon2-4.0.5.tgz
Set Path Variable for MongoDB:
Now you can either copy the downloaded binaries into a directory which is already set as your PATH variable i.e /usr/local/bin or
Modify your user’s PATH environment variable to include this directory like edit your shell’s initialization script (e.g ~/.bashrc):
For this replace with your extracted MongoDB archive path respectively
Through this process the default directory paths are not created. So you can create them as follows:
# mkdir -p /var/lib/mongo # mkdir -p /var/log/mongodb
By default, MongoDB runs through mongod user account. So after creating user “mongod”, set the owner and group of these directories as follows:
# chown -R mongod:mongod
To use Non-Default locations:
You can also edit the MongoDB configuration file i.e /etc/mongod.conf and set the db path and log path as per your requirement.
storage.dbPath (specify a new db path) systemLog.path (specify a new log file path)
After successfully installing the MongoDB, start it by the following command and make sure to persistently start the service during reboot.
# sudo systemctl start mongod # sudo systemctl enable mongod # sudo systemctl status mongod
Using MongoDB Shell:
Start using MongoDB via mongo shell on your machine as the
You can install MongoDB server by using any one of the above mentioned method. In up-coming tutorial we will cover about the replication in MongoDB and also about backups and restore procedures. So make sure to subscribe to our newsletter and begin your journey to become a MongoDB expert.
