I don't this is a very common question, I'm only asking it because I've already started some ec2 instances using the method I'll explain bellow and I succed, maybe EC2 changed something the right away to connect it by HTTP using public dns. Here are the steps I've always done and I don't know why it isn't working anymore.
public dns: ec2-23-22-52-143.compute-1.amazonaws.com
1 - Settup the default security group, that is oppened for every traffic
2 - Add IAM policity to this ec2, as you can see IAM function bellow
3 - Access SSH and configure nginx, I used putty and could enter on the instance. The configuration for nginx is /etc/nginx/sites-avaiable/default
## default nginx config
server {
listen 80 default_server;
server_name _;
# front-end
location / {
root /var/www/html;
try_files $uri /index.html;
}
# node api
location /api/ {
proxy_pass http://localhost:3000/;
}
}
4 - Clone both my front-end and back-end repositories from github
5 - build production and move to /var/www/html all frontend dist files
6 - Start my node.js server using pm2
7 - Start nginx
sudo nginx -t
sudo systemctl start nginx
sudo netstat -plant | grep 80
tcp 0 0 0.0.0.0:80 0.0.0.0:* LISTEN 21159/nginx: master
As you can see the port:80 is being listening by nginx
Guys I have no ideia why I can't access the public dns of this instance, I made everything identical as I've done in the past, It has always been working doing these steps, anything has changed using AWS EC2 ubuntu 20 instance, let me know. Thanks a lot, I'm headaching trying to figure this out.
Last steps to try to solve it is check nginx logs
cd /var/log/nginx
2022/04/05 09:42:02 [error] 8216#8216: *1 directory index of "/var/www/html/" is forbidden, client: 103.178.236.40, server: _, request: "GET http://example.>
But even doing this, it has not solved the issue:
sudo chmod -R 777 /var/www/html
