This demo is based on: Amazon Linux 2 AMI (AWS EC2)
The first step is to turn yourself as Root user and upgrade your EC2 instance:
sudo su
yum upgrade
The two most popular program to run web server are Apache and Nginx. In this tutorial I will use Nginx to show the steps.
I masked my IP address as ADDRESS for security reasons.
[root@ip-ADDRESS ec2-user]# yum install nginx
Loaded plugins: extras_suggestions, langpacks, priorities, update-motd
No package nginx available.
Error: Nothing to do
nginx is available in Amazon Linux Extra topic "nginx1"
To use, run
# sudo amazon-linux-extras install nginx1
Learn more at
https://aws.amazon.com/amazon-linux-2/faqs/#Amazon_Linux_Extras
Then run the command as Amazon recommended:
[root@ip-ADDRESS ec2-user]# sudo amazon-linux-extras install nginx1
If the installation is completed successfully, the next step is to run the Nginx.
But before running the Nginx, let's try read the initial web content of Nginx using curl command:
[root@ip-ADDRESS ec2-user]#curl localhost:80
When the Nginx service is stopped, you will get the following message:
[root@ip-ADDRESS ec2-user]# curl localhost:80
curl: (7) Failed to connect to localhost port 80 after 0 ms: Connection refused
So, let's start the Nginx service:
[root@ip-ADDRESS ec2-user]# service nginx start
Redirecting to /bin/systemctl start nginx.service
And then, type the following command:
[root@ip-ADDRESS ec2-user]# curl localhost:80
You will get:

If you fail to start Nginx service, it might be that the hosting provider preinstalled Apache on your instance by default during a fresh install. Just run the following commands:
sudo fuser -k 80/tcp
sudo fuser -k 443/tcp
Then it might be OK to restart it:
sudo service nginx restart
By now, if you paste your public ip address in your browser, you still cannot see the index Nginx webpage. This is because you haven't open the 80 port in your AWS Security Group.
Now edit inbound rules, and add 80 port to your security groups.
The last step, to refresh your web browser again which you typed your public ip address of your EC2 instance, and you will get the welcome page of Nginx.
Welcome to Nginx on Amazon Linux.
