Welcome again, Hope you are doing well.

a) Download MongoDB is one step process

sudo apt install mongodb

Now be prepare for elastic search installation and follow the following commands

b) Install apt-transport-https

sudo apt-get install apt-transport-https

c) Get the elasticsearch package from internet

wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-7.7.1-amd64.deb

d) Get the secured hashed (sha-512) package

wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-7.7.1-amd64.deb.sha512

e) Compare the SHA of the downloaded Debian package and the published checksum

shasum -a 512 -c elasticsearch-7.7.1-amd64.deb.sha512

f) Finally install downloaded debian package

sudo dpkg -i elasticsearch-7.7.1-amd64.deb

g) To start Elastic Search

sudo -i service elasticsearch start

h) To start MongoDB

sudo service mongodb start

Till Now Installation of MongoDB and Elastic Search has been done.

Now we will see how to Restore any backup data stored in MongoDB again.

i) So after starting MongoDB type ‘mongo’ and it will open an interactive mongo shell where you can write mongodb commands/queries.

After coming in the mongo shell first drop the production database present there.

This is three step as shown below:

• First is open mongo shell using following

mongo

• When mongo shell is opened the list all databases present there using following

show dbs

• If Production database is present there then first drop it

use production
db.dropDatabase()

j) After dropping the production database exit the mongo shell using CTRL+C and restore Production database with your data. You have to provide the path of data where data is present.

mongorestore -d production  path_of_data_where_it_is_present

Now you are ready to go.

Thank You!
