Error installing nginx in Ubuntu 18 under AWS

[mstdmstdd]

Hello,
I installed Ubuntu 18 instance under AWS and I found this article with nginx installation(I used this article with installation in Ubuntu 18 under Digital Ocean)
https://devmarketer.io/learn/deploy-laravel-5-app-lemp-stack-ubuntu-nginx/

I installed nginx, but I am not sure whioch must be servwer name in nginx configurations :

server {
        listen 80 default_server;
        listen [::]:80 default_server;


        root /var/www/html;

        index index.php index.html index.htm index.nginx-debian.html;

        server_name ec2-NN-NN-NN-NN.us-east-2.compute.amazonaws.com;

        location / {
                # First attempt to serve request as file, then
                # as directory, then fall back to displaying a 404.
                try_files $uri $uri/ =404;
        }


        location ~ \.php$ {
                include snippets/fastcgi-php.conf;
                fastcgi_pass unix:/run/php/php7.0-fpm.sock;
        }

        location ~ /\.ht {
                deny all;
        }

where 
my Publick DNS
NN-NN-NN-NN.us-east-2.compute.amazonaws.comI checked nginx syntax and restarted php and nginx

$ sudo nginx -t
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful
$ sudo systemctl restart php7.2-fpm
$ sudo service nginx restart

But running url
http://NN-NN-NN-NN.us-east-2.compute.amazonaws.com/I got error:

Quote

 

.us-east-2.compute.amazonaws.com’s server IP address could not be found.
DNS_PROBE_FINISHED_NXDOMAIN

 

But not nginx greeting page.
Is it on AWS different and what did I miss?

Thanks!

The server_name is the domain name of your website. If you want to go to http://ec2-whatever then your server_name would be ec2-whatever.

If DNS isn't resolving yet and you're sure you typed it correctly (so copy/paste it), wait a while and try again.

[mstdmstdd]

looks  like the problem was that in security group i forgot set httphttps access

If there is a way to set  Multiple Websites on Single instance  with nginx  ?

[requinix]

A security group shouldn't prevent DNS from working.

Yes, you can do multiple websites. Guide

[mstdmstdd]

Thank you for the link, but with quick review I did not find how to create multiple websites under one server?

 

 

[requinix]

The page does say, but I'll admit it's not very clear about how.

You've seen the server { } blocks, right? You can have more than one for different server_names and/or listens.

On Debian-based Linux there is typically a /etc/nginx/sites-enabled and sites-available. sites-available is where multiple site configuration files are, and sites-enabled has a symlink to each one that should be enabled.

I searched how to install multiple projects on nginx server and found some articles, like
https://medium.freecodecamp.org/how-you-can-host-multiple-domain-names-and-projects-in-one-vps-7aed4f56e7a1

I added new server block with rather long server name(which I created in freenom)
Checking the syntax I got error that server_names_hash_bucket_size must be set to 64

I tried to set and and did not find valid place for it.
I found that it must be added under http block. I tried to add http block in my /etc/nginx/sites-available/default
but got syntax error :

$ sudo nginx -t 
nginx: [emerg] "http" directive is not allowed here in /etc/nginx/sites-enabled/default:22
nginx: configuration file /etc/nginx/nginx.conf test failed

My /etc/nginx/sites-available/default :

Which is valid syntax ?

Thanks!

Don't edit the default file. Revert it to the original, disable it from sites-enabled, then create a new file in sites-available.

The file only needs one server block, or two if you want http+https support. No http block, that's nginx configuration and would belong somewhere else if you needed one at all.

[mstdmstdd]

Could, you please provide an example or a link to such file ?

[requinix]

Here. This looks like a reasonable example I just happened to find lying around somewhere.

server {

listen 80;

root /var/www/votes/public;

index index.php index.html index.htm index.nginx-debian.html;

server_name rather-long-name-demo.demo-apps.tk;

location / {
try_files $uri $uri/ /index.php?$query_string;
}


location ~ \.php$ {
include snippets/fastcgi-php.conf;
fastcgi_pass unix:/run/php/php7.2-fpm.sock;
}

location ~ /\.ht {
deny all;
}

access_log /var/www/votes/storage/logs;

# server_names_hash_bucket_size 64;

}
