How To Install and Configure MongoDB NoSQL Database To Linux, Ubuntu, Debian, CentOS, Fedora

Sql is very powerful language to query, insert, delete, modify data. Recents years the IT industry have developed some alternative ways to store and retrieve data. NoSQL type database servers become very popular. MongoDb is an NoSQL database server to store and retrieve data. In this tutorial we will look how to install MongoDB on Linux and distributions like Ubuntu, Debian, CentOS, Fedora, RedHat.

Fedora, CentOS, RedHat

We will use yum of dnfpackage managers to install MongoDB. Alternatively we can download installation package from MongoDB website.

$ sudo dnf install mongodb-server

Ubuntu, Debian

We will  use apt package manager

$ sudo apt install mongodb-server

Check Service Status

After the installation we need to start the MongoDB service which is named mongod . The first step is checking the mongod service status.

$ sudo systemctl status mongod.service

As we can see it is stopped.

Start MongoDB Service with Systemctl

Systemctl is de facto and new tool to manage services in Linux. We will use systemctl start command to start MongoDB service. We need root privileges to start  and stop services.

$ sudo systemctl start mongod.service

Check MongoDB Ports

One of the most occured problem is firewall which prevents to access MongoDB database server ports. We can can access with telnet from remote host like below.

First we will look on MongoDB server which ports are listened. We will use netstat -tl command. MongoDB generally and by default uses port range 27017-27018 .

$ netstat -tln

$ telnet localhost 27017

We can see that we have no problem about network connection. It we get an message like Connection refused this means we have problem with network connection to the remote host.
