MongoDB is a NoSQL database intended for storing large amounts of data in document-oriented storage with dynamic schemas. NoSQL 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.


Step 1: Add the MongoDB Repository

Nano Editor is the best for editing i think so i always use nano editor so you can use any kind of editor does not matter.
[root@hackthesec]# touch /etc/yum.repos.d/mongodb.repo
[root@hackthesec]# nano /etc/yum.repos.d/mongodb.repo


If you are running a 64-bit system, add the following information to the file you’ve created, using i to insert:
[mongodb]
name=MongoDB Repository
baseurl=http://downloads-distro.mongodb.org/repo/redhat/os/x86_64/
gpgcheck=0
enabled=1
Then exit and save the file with the command :Ctrl+X after that Y after that Enter Button
If you are running a 32-bit system, add the following information to the file you’ve created, using i to insert:
[mongodb]
name=MongoDB Repository
baseurl=http://downloads-distro.mongodb.org/repo/redhat/os/i686/
gpgcheck=0
enabled=1
Then exit and save the file with the command :Ctrl+X after that Y after that Enter Button

Step 2: Install MongoDB

As a matter of best practice we’ll update our packages:
[root@hackthesec]# yum -y update
At this point, installing MongoDB is as simple as running just one command:
[root@hackthesec.co.in]# yum -y install mongodb-org mongodb-org-serve

Step 3: Get MongoDB Running

Start-Up MongoDB
systemctl start mongod
Check MongoDB Service Status
systemctl status mongod

Summary List of Status Statistics (Continuous)
mongostat
Summary List of Status Statistics (5 Rows, Summarized Every 2 Seconds)
mongostat --rowcount 5 2
Enter the MongoDB Command Line
mongo
By default, running this command will look for a MongoDB server listening on port 27017 on the localhost interface.
If you’d like to connect to a MongoDB server running on a different port, then use the –port option. For example, if you wanted to connect to a local MongoDB server listening on port 22222, then you’d issue the following command:
mongo --port 22222
Shutdown MongoDB
systemctl stop mongod
