Installing MongoDB under Ubuntu16.04lts

1. Installing MongoDB

First step: Import the public key used by the package management system

Ubuntu package management tools (i.e. dpkg , and apt ) ensure package consistency and authenticity by requiring the reseller to sign the package with GPG key. Issue the following command to import the MongoDB public GPG key:sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv 0C49F3730359A14518585931BC711F9BA15703C6

Step Two: Create a list file for MongoDB

First, to determine the version of the Ubuntu system you are using, to view the current kernel version, open the terminal and type the uname -r command to view the kernel version:

View kernel version commands as follows:

[Email protected]:~$ uname-r
4.10.0-33-generic

Check whether the operating system is 32-bit or 64-bit:

[Email protected]:~$ sudo uname--m
x86_64

View Ubuntu version

[Email protected]:~$ sudo lsb_release-a
No LSB modules is available.
Distributor Id:ubuntu
Description:ubuntu 16.04.3 LTS
release:16.04
Codename:xenial

Create a list file using the commands that are appropriate for your Ubuntu version /etc/apt/sources.list.d/mongodb-org-3.4.list :

Ubuntu 14.04:

$ echo "deb [ arch=amd64 ] http://repo.mongodb.org/apt/ubuntu trusty/mongodb-org/3.4 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-3.4.list

Ubuntu 16.04:

$ echo "deb [ arch=amd64,arm64 ] http://repo.mongodb.org/apt/ubuntu xenial/mongodb-org/3.4 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-3.4.list

Step three: Reload the local package database

Issue the following command to reload the local package database:

sudo apt-get update

Fourth Step: Install MongoDB Package

Install the latest stable version of MongoDB. Issue the following command:

sudo apt-get install -y mongodb-org

If you change the user running the MongoDB process, you can modify /var/lib/mongodb and /var/log/mongodb access control permissions on the directory so that the user can access the directories.

Start MongoDB

Issue the following command to start MongoDB:

$ sudo service mongod start
