[PYTHON] [AWS CLI] Enable the AWS CLI on Red Hat Enterprise Linux 8

Target

· Install the AWS CLI on a Red Hat Enterprise Linux 8-based EC2 instance. -Enable resource operations in the target AWS account using the AWS CLI.

Trigger

It is almost a memorandum. When I tried to use the AWS CLI (*) on Red Hat Enterprise Linux 8 I wrote it because I was a little annoyed by command not found in python related commands.

※AWS CLI A type of API provided by AWS that enables AWS resource operations on the command line.

Usage environment

Hardware: ** AWS EC2 server ** OS(AMI) : Red Hat Enterprise Linux 8 (HVM), SSD Volume Type Other software: Python 3.8.0 aws-cli/1.18.81 Python/3.8.0 Linux/4.18.0-193.el8.x86_64 botocore/1.17.4

Workflow

Item number title
1 python installation
2 AWS CLI installation
3 Issuance of access key ID and secret access key
4 AWS CLI operation check

procedure

1. Install python

Since the AWS CLI is based on python, you need to have the python execution environment installed first. But Red Hat Enterprise Linux 8 doesn't seem to have python installed by default, First, install it (*). As of June 17, 2020, I installed the latest python3.8 with yum.

** ① Install python3.8 ** Run yum install python38 ⇒ It should be output as Complete!.

[[email protected] ~]# yum install python38
Installed:
  python38-3.8.0-6.module+el8.2.0+5978+503155c0.x86_64                       python38-libs-3.8.0-6.module+el8.2.0+5978+503155c0.x86_64
  python38-pip-19.2.3-5.module+el8.2.0+5979+f9f0b1d2.noarch                  python38-pip-wheel-19.2.3-5.module+el8.2.0+5979+f9f0b1d2.noarch
  python38-setuptools-41.6.0-4.module+el8.2.0+5978+503155c0.noarch           python38-setuptools-wheel-41.6.0-4.module+el8.2.0+5978+503155c0.noarch

Complete!

** ② python command operation check ** Execute python3 --version (Note that in RHEL the version must also be included in the command) ⇒ Version information should be output normally


[[email protected] ~]# python3 --version
Python 3.8.0

2. Install AWS CLI

** ① AWS CLI installation ** Run pip3 install awscli ⇒ It should be output as Successfully installed.

[[email protected] ~]# pip3 install awscli
WARNING: Running pip install with root privileges is generally not a good idea. Try `pip3 install --user` instead.
