In this tutorial we will show you how to install and configuration MongoDB on CentOS 7. For those of you who didn’t know, MongoDB is a NoSQL document-oriented database. Refers to a database with a data model other than the tabular format used in relational databases such as MySQL, PostgreSQL, and Microsoft SQL. MongoDB features include: full index support, replication, high availability, and auto-sharding. It is a cross-platform and it makes the process of data integration faster and much easier. Since it is free and open-source, MongoDB is used by number of websites and organizations.
This article assumes you have at least basic knowledge of linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo’ to the commands to get root privileges. I will show you through the step by step installation MongoDB on a CentOS 7 server.
Install MongoDB on CentOS 7
Step 1. First, add the official MongoDB repository to your system.
You will need to setup the official repository on your server. To do so, create a file in /etc/yum.repos.d/mongodb.repo and populate it with the following data:
## CentOS 64-bit ##
## CentOS 32-bit ##
Five packages are available from the above repositories:
- mongodb-org – Meta package that will install the following four packages.
- mongodb-org-server – MongoDB server, configuration file, and startup/shutdown scripts.
- mongodb-org-mongos – MongoDB service for a shard cluster.
- mongodb-org-shell – MongoDB shell used for interacting with MongoDB.
- mongodb-org-tools – Various MongoDB tools such as mongoexport, mongodump, mongorestore, etc.
Step 2. Installing mongoDB packages.
Installing MongoDB is as simple as running just one command:
yum -y install mongodb-org mongodb-org-server
MongoDB daemon should be enabled to start on boot:
systemctl enable mongod
systemctl start mongod
Step 3. Verifying MongoDB database.
Unlike MySQL, there aren’t a lot of graphical UIs and/or desktop clients available for MongoDB. There are of course language bindings, to allow us to use PHP and other languages to access the database, but a lot of the fundamental work is done using the command-line client.
