Using AWS with Linux

Introduction

Amazon Web Services (AWS) is a comprehensive, evolving cloud computing platform provided by Amazon. It offers a mix of infrastructure as a service (IaaS), platform as a service (PaaS), and packaged software as a service (SaaS) offerings. This tutorial will guide you through the process of using AWS with a Linux operating system from start to finish.

Prerequisites

Before you begin, ensure you have the following:

• An AWS account
• Basic knowledge of Linux commands
• A Linux system or server

Installing AWS CLI on Linux

The AWS Command Line Interface (CLI) is a unified tool to manage your AWS services. To install AWS CLI on Linux, follow these steps:

curl "https://awscli.amazonaws.com/awscli-exe-linux-x86_64.zip" -o "awscliv2.zip"

unzip awscliv2.zip

sudo ./aws/install

Verify the installation:

aws --version

Configuring AWS CLI

After installing AWS CLI, configure it using your AWS credentials:

aws configure

You will be prompted to enter your AWS Access Key ID, Secret Access Key, region, and output format:

Launching an EC2 Instance

To launch an EC2 instance using AWS CLI, execute the following command:

aws ec2 run-instances --image-id ami-0abcdef1234567890 --count 1 --instance-type t2.micro --key-name MyKeyPair --security-groups my-sg

Replace the placeholders with your own values:

• --image-id: The ID of the AMI (Amazon Machine Image) to use
• --count: Number of instances to launch
• --instance-type: The type of instance to launch
• --key-name: The name of the key pair to use
• --security-groups: The security group to associate with the instance

Managing EC2 Instances

To list your running EC2 instances, use:

aws ec2 describe-instances

To stop an instance:

aws ec2 stop-instances --instance-ids i-0abcdef1234567890

To start an instance:

aws ec2 start-instances --instance-ids i-0abcdef1234567890

To terminate an instance:

aws ec2 terminate-instances --instance-ids i-0abcdef1234567890

Using S3 with AWS CLI

Amazon S3 (Simple Storage Service) is an object storage service. To create a new bucket:

aws s3 mb s3://my-new-bucket

To list all buckets:

aws s3 ls

To upload a file to a bucket:

aws s3 cp myfile.txt s3://my-new-bucket/

To download a file from a bucket:

aws s3 cp s3://my-new-bucket/myfile.txt ./

Conclusion

In this tutorial, you learned how to use AWS with a Linux system. You installed and configured AWS CLI, launched and managed EC2 instances, and used S3 for storage. AWS offers a vast array of services, and the CLI is a powerful tool to manage your cloud resources efficiently.
