Building an environment to execute python programs on AWS EC2

I tried to run .py in my local environment, but I couldn't understand Python3, pip3, Python, and Pip, so I decided to run it on AWS.

How to do it : zap: Comments welcome: zap:

1. Register with AWS

Googling with aws and creating an account Just enter your email address and password

2. Select EC2

There are various services, but click EC2

3. Create a new instance

You can set it according to AWS Getting Started. All free guy

• AMI (Amazon Machime Image): Amazon Linux 2 AMI （x86） --Instance type: t2.micro

• There are two types of AMI, x86 and ARM. It worked on x86 for the time being, but I don't know what's different Someone tell me

After selecting this, click the blue button "Review & Launch Instance"

A pop-up asking you to save the key pair will appear, so select "Create New Key Pair" and save the .pem file.

• If you created an instance before, you can use the same one as before by selecting "Choose existing key pair".
• Do not use this .pem file when connecting to the instance with a browser.

4. Connect to instance

Go to the EC2 Dashboard and click the checkbox next to instance → "Connect"

A pop-up will appear, so select the best one to connect with your browser (I think other things are fine, but I'm not sure about SSH, so I chose a browser)

If you see a black screen in your browser, it's ok

5. Environment construction

From here, we will build an environment for executing python programs. @ Kenta1984's article

things to do: --Insert python3 --Insert git

git uses gist when transferring Python files to an EC2 instance, so put it in I don't need anyone to use scp

#Update the included package for the time being
sudo yum update -y
#Insert Python3
sudo yum install python3 -y
#Insert git (optional)
sudo yum install git

By the way, ** If you include Python3, pip3 will also be included ** So you don't have to insuko pip3 separately

Reference: https://git-scm.com/download/linux

6. Create a file → send to EC2 instance

The reality is that you just put the file on gist and clone it to your instance.

: bulb: gist can be cloned and pulled just like git

6-1. Make a gist

https://gist.github.com/

If you paste the code written in VS Code etc., it's ok : warning: Please include the extension in the file name

6-2. Clone gist

At: arrow_down :, select Clone via HTTPS → Copy

On the black screen (browser tab opened in 4) connecting to the EC2 instance, clone gist like always clone git repository

$ git clone <gist URL>

6-3. Program execution

#Move to gist directory
cd my-gists #Directory names vary from person to person, if you don't know, ls
#Program execution
python3 hoge.py #Change the file name to your own

Summary

1. Create an instance on EC2
2. Connect to the instance with a browser
3. Put python3 and git in the instance with sudo yum install
4. Paste the python program code into gist
5. Clone gist
6. Program execution
