The AWS CLI is an essential tool for developers and sysadmin to automate and interact with AWS cloud services. It is an open-source tool built on the AWS SDL for Python. As a result, you no longer need to use AWS Management Console. Instead, you can use a Linux terminal and commands for managing AWS resources. Let us see how to install AWS CLI on Linux using the command-line options.

If you found this guide on how to install the AWS CLI on Linux helpful, you may also like the article about installing a Linux virtual machine on Windows 7.

Initiating AWS CLI Installation on Linux

Begin by opening your terminal application. Depending on your specific Linux distribution, you’ll need to execute a particular command to install the AWS CLI toolkit. To install the most recent version of the AWS CLI, follow the pip installation method provided below.

Linux DistributionInstallation Command
Debian/Ubuntusudo apt install awscli
Fedorasudo dnf install awscli
RHEL/CentOS/Rocky/Alma Linuxsudo dnf install awscli (Ensure EPEL repo)
Alpineapk add aws-cli
Arch Linuxsudo pacman -S aws-cli
OpenSUSE/SUSE Linuxsudo zypper in aws-cli

To install AWS CLI version 1.x using the PIP generic method, run the following command:

python3 -m pip install awscli

If you prefer to install AWS CLI version 2, you can do so with these commands:

python3 -m pip install awscliv2

~/.local/bin/awscliv2 –install

Ensure that you include ~/.local/bin/ in your $PATH. Here’s an example of how to set up your $PATH on Linux:

# Step #1. Set PATH variable #

echo ‘export PATH=$PATH:~/.local/bin’ >>~/.bashrc

# Step #2. Set bash alias too #

echo ‘alias aws=”awsv2″‘ >>~/.bashrc

# Step #3. Use the source command to load changes #

source ~/.bashrc

After installation, you can check the AWS CLI version by running the following command:

aws –version

The output may vary depending on your package manager and Linux distribution. For example, here is the output from my Ubuntu 20.04 LTS developer workstation:

aws-cli/1.18.69 Python/3.8.10 Linux/5.13.0-35-generic botocore/1.16.19

Here are the outputs from version 2 (v2):

2.1.1

AWS CLI v2 command: /home/ubuntu/.awscliv2/binaries/aws

aws-cli/2.4.28 Python/3.8.8 Linux/5.13.0-37-generic exe/x86_64.ubuntu.22 prompt/off

To configure the AWS CLI with API access keys, follow these steps:

  • Log in to the AWS Management Console;
  • If you don’t already have API access keys, obtain them;
  • Configure the AWS CLI with the obtained API access keys using the following command:

aws configure

Up to this point, you have successfully installed the AWS CLI, configured access, and now it’s time to verify its functionality. Begin by running the ‘aws s3 ls’ command to list your AWS S3 resources:

aws s3 ls

When everything is correctly configured, you should see the following output:

2016-07-25 16:11:06 xyz-project-freenas

2020-07-03 13:55:47 xyz-project-forum

….

..

Best Practices for Securing AWS CLI Credentials

It’s important to be aware that your AWS CLI credentials are stored in plain text within the ~/.aws/ directory. Consequently, it’s crucial not to share the ~/.aws/ directory and its associated files. You can view the credentials using the ‘cat’ command:

cat ~/.aws/credentials

To enhance security, there are options available. You can store your credentials in an encrypted format, or you can leverage AWS Multi-Factor Authentication (MFA). Enabling MFA is a best practice as it adds an additional layer of protection to your credentials. In an upcoming tutorial, we’ll explore combining these security measures using a wrapper script for even greater protection.

Locating the AWS CLI on Linux

To determine the location of the AWS CLI on your Linux machine, you can utilize various commands such as ‘find,’ ‘type,’ ‘whereis,’ or ‘which.’ Here’s an example using the ‘find’ command:

type aws

which aws

whereis aws

# this will take more time and may give many results #

sudo find / -type f -name "aws"

AWS CLI Configuration Examples

Below are examples of how to configure the AWS CLI:

aws configure wizard

Outputs:

usage: aws [options] <command> <subcommand> [<subcommand> ...] [parameters]

To see help text, you can run:

aws help

  aws <command> help

  aws <command> <subcommand> help

aws: error: argument subcommand: Invalid choice, valid choices are:

list                                     | get                                     

set                                      | add-model

To view your current configuration settings:

aws configure list

Configure the AWS CLI using Single Sign-On (SSO):

aws configure sso

Wondering how to enhance the typography on your Linux system? This guide will walk you through the ins and outs of installing fonts on Linux, providing insights into different methods, troubleshooting tips, and optimizing font usage for a seamless visual experience.

Understanding Font Installation on Linux

Before we dive into the installation process, let’s grasp the fundamentals of font installation on Linux. Fonts play a crucial role in defining the visual aesthetics of your system. Whether you’re a designer, developer, or simply someone with a keen eye for design, customizing fonts allows you to personalize your Linux experience.

Exploring a new operating system installation can be quite exhilarating, and the good news is that you can now do it without jeopardizing your existing setup. Whether you’re keen to delve into bash scripting, experiment with new software, or test hardware compatibility, running a Linux virtual machine (VM) is your ticket to the destination. The best part? It only takes a few minutes to get up and running.

While learning how to install Ubuntu via a Virtual Machine on Windows 7, you can also explore articles like “How to Install Etcher on Linux” to expand your knowledge of Linux software management.

Understanding Virtualization Terms and Storage Options

Before we dive in, it’s crucial to clarify some terminology. In the realm of virtualization, your existing operating system is referred to as the host OS, while the one you’re about to install is known as the guest. Simple, isn’t it? Now is also a perfect moment to decide whether you want to create a fixed-size or dynamically allocated virtual hard drive for your VM. The distinction is fairly straightforward: a fixed-size drive allocates a specific amount of storage space for the guest OS, whereas a dynamically allocated drive expands its space as required. Depending on your intended usage for the VM, you should be able to determine whether you can accurately predict the physical storage space needed. Although there are ways to address storage issues later, such as increasing a virtual disk’s capacity, it’s far more convenient to make the right choice from the outset. Ready to proceed? Let’s get started.

How to Install and Configure VirtualBox on Windows 7?

This comprehensive guide is designed to walk you through the process of installing VirtualBox on a Windows 7 system, followed by detailed steps to configure a new virtual machine within the VirtualBox environment.

Step 1: Installing VirtualBox on Windows 7

To begin the installation of VirtualBox on your Windows 7 system, follow these steps closely:

  • Navigate to the official VirtualBox website at https://www.virtualbox.org/wiki/Downloads to access the download section;
  • Select and download the latest version of VirtualBox specifically designed for Windows hosts (supports both x86 and amd64 architectures);
  • Choose the “Save As” option to download the installation file to your computer;
  • Once the download is complete, locate and run the downloaded .exe file to start the installation process;
  • If a security warning appears from Windows, select “Run” to proceed;
  • Follow the installation prompts, accepting the default configuration options provided by the VirtualBox installer.

Upon completing these steps, VirtualBox will launch, indicating that the installation process has been successfully completed. You are now ready to move on to the next phase, which involves setting up a new virtual machine.

Step 2: Configuring a New Virtual Machine

With VirtualBox installed, the next step is to configure a new virtual machine (VM) to run your desired operating system. Here’s how to set it up:

  1. Upon finishing the installation, VirtualBox will guide you through the process of creating a new VM. If the “Create Virtual Machine” dialog does not appear automatically, click on “New” in the top left corner of the VirtualBox window;
  2. Start by entering a name for your VM and selecting the operating system type. For this guide, we’ll choose Linux and specify Ubuntu as the OS version;
  3. Next, allocate memory to your VM. The default memory size is generally sufficient for basic tasks. We recommend 512MB as a good starting point, but be mindful that allocating too much or too little memory can affect performance;
  4. Proceed to create a virtual hard drive where your VM’s files will reside. A Virtual Disk Image (VDI) is preferable, especially if you don’t have other VMs.
  5. When selecting the hard drive type, you can choose between a dynamically allocated or fixed size. If disk space is not a concern, a fixed size might offer slight performance improvements;
  6. Determine the amount of storage to allocate to your VM. An 8GB virtual hard drive is adequate for most purposes, but remember that the operating system will consume some of this space, so plan for at least 5GB for the OS itself;
  7. During the setup, you may encounter a notification regarding optical disks. You can ignore this message for now as it does not impact the initial configuration process.

Step 3: Installation of Ubuntu on the Virtual Machine

To equip your VM with Ubuntu, carefully follow the steps outlined below:

  • Begin by obtaining the latest Ubuntu distribution. Visit Ubuntu’s official download page to download the most recent version. While there, you’ll have the option to contribute financially to the project—a gesture that, although optional, is highly encouraged for supporting the continued development of Ubuntu;
  • If not already running, launch VirtualBox to proceed with the setup;
  • Select your previously created VM, then access its “Settings” through the corresponding option;
  • Within the settings menu, navigate to the “Storage” section to manage your VM’s storage devices;
  • In the storage tree, identify and select the disc icon labeled “Empty.” If the label differs, select the icon regardless;
  • Look for a small disc icon accompanied by a downward arrow, located near the “Attributes” section on the right-hand side of the storage settings window. Click this icon to proceed;
  • Use the file dialog to locate and select the Ubuntu .iso file you downloaded earlier, effectively mounting it as a virtual disc;
  • Confirm your settings by clicking “OK,” which will return you to the main VirtualBox window;
  • With everything set, initiate the VM by clicking “Start.”

With the Ubuntu .iso file now mounted, your VM will boot from this virtual disc, simulating the experience of booting a computer from a CD or DVD. During this phase, you’ll encounter various notifications regarding the integration and use of your mouse, keyboard, and other system resources within the VM. While informative, these messages typically don’t require any immediate action.

Step 4: Completing the Ubuntu Installation

Your VM will now proceed as if it were a standalone computer:

  • Follow the on-screen instructions to install Ubuntu. Given that you’re using the latest version of the OS, updating it immediately after installation may not be necessary;
  • If you find yourself uncertain at any point, rely on the visual prompts provided during the installation. This phase is straightforward and marks the culmination of your setup efforts;
  • Once Ubuntu is installed, shut down the VM to apply the final touches;
  • Reopen the VirtualBox settings for your VM, ensuring that the IDE storage configuration is set to “Empty.” This step prevents the VM from booting into the installation setup on subsequent starts, allowing it to launch Ubuntu directly instead.

Congratulations! Your virtual machine is now equipped with Ubuntu, ready for you to explore its capabilities. Should you encounter performance issues, consider creating another VM with increased memory allocation. My personal use of Ubuntu is limited to terminal access, which requires minimal resources.
