AWS or Amazon web services is a cloud service platform that provides on-demand computational services, databases, storage space, and many more services. EC2 or Elastic Compute Cloud is a scalable computing service launched on the AWS cloud platform. In simpler words, EC2 is nothing but a virtual computer on which we can perform all our tasks and we have the authority to configure, launch or even dissipate this virtual computer.

In this article, we will learn how to install Python on AWS EC2.

Prerequisite:

  1. AWS account.
  2. EC2 Instance.
  3. User with privileges to create Instance.

Installing Python on AWS EC2 :

Follow the below steps to install Python on AWS EC2:

Step 1: Create an AWS Elastic Cloud Compute Instance.

Step 2: Start the EC2 instance that you have created in Step 1.

Step 3: Connect to your EC2 Instance by clicking on Connect Button. 

Step 4: A prompt will pop up after connecting.

Step 5: Check if Python is already installed or not on our AWS EC2.

python --version

Step 6: At first update, Ubuntu packages by using the following command.

sudo apt update

Step 7: If Python3 is not installed on your AWS EC2, then install Python3 using the following command.

sudo apt-get install python3.7

Step 8: Wait for the process to end.

Step 9: We have successfully installed Python3 on AWS EC2, to check if Python3 is successfully installed or not, verify using the following command.

python3 --version

In this way, we can Install Python3 on our EC2 instance using EC2 Instance Connect.

Let’s try to create a Python program on nano and then execute that python program on our EC2 instance:

 

Python3




#example using python3
#gfg.py
print("Geeks for Geeks is the best website for a programmer")


Output

Geeks for Geeks is the best website for a programmer

Output

Note: If you also use a free tier account, make sure you delete all the resources you have used before logging out. 

Setting up a virtual environment for Python on the EC2 instance:

This can be useful for isolating different Python projects and their dependencies, as well as for managing multiple versions of Python packages. To set up a virtual environment, you can use the virtualenv package, which can be installed using pip3 install virtualenv. Once virtualenv is installed, you can create a new virtual environment with a specific Python version by running the command virtualenv -p python3 envname, where envname is the name of your virtual environment. You can then activate the virtual environment using the command source envname/bin/activate. Within the virtual environment, you can install packages using pip3 install as usual, and they will be isolated from the global Python environment on the EC2 instance. When you are finished working in the virtual environment, you can deactivate it using the deactivate command.
