❌ Install nginx as root user, switch to root user before installing

sudo su -

Enable and Install EPEL repo on AWS EC2 Amazon Linux 2 instance

Step 1. Firstly, check if the EPEL repository is enabled:

sudo amazon-linux-extras list | grep epel

If you get an output like:

24  epel      available    [ =7.11  =stable ]

Then it means that you should enable it before installing Nginx.

Step 2. To enable the EPEL repo on Amazon Linux 2 instance run:

sudo amazon-linux-extras enable epel

Step 3. Now you should be able to install the EPEL repo:

sudo yum install epel-release

Install Nginx on AWS EC2 Amazon Linux 2 instance

Step 1. Once the EPEL repo is installed you can install the Nginx latest version as well:

sudo yum install nginx

Step 2. Verify the installation:

nginx -v

Output:

nginx version: nginx/1.20.1
