After setting up server blocks, Nginx is not serving my domain name

I am in the process of deploying my MERN app to a Digital Ocean droplet (Ubuntu 20.04 server).

I followed the steps in the following tutorial to install Nginx. [I have completed all the previous steps]

https://www.digitalocean.com/community/tutorials/how-to-install-nginx-on-ubuntu-20-04

When I visit http://134.122.112.22, I see the Nginx landing page, as expected. enter image description here

However, after setting up server blocks, when I visit http://sundaray.io, I get the following error. enter image description here

sundaray.io is my domain name.

When I run the command /var/log/nginx/error.log, I see the following: enter image description here

How can I fix the error?

EDIT-1

SERVER BLOCK In order to create the server block, I executed the following commands in order:

  1. mkdir -p /var/www/sundaray.io/html
  2. nano /etc/nginx/sites-available/sundaray.io Then, I pasted in the following configuration block.
server {
        listen 80;
        listen [::]:80;

        root /var/www/sundaray.io/html;
        index index.html index.htm index.nginx-debian.html;

        server_name sundaray.io www.sundaray.io;

        location / {
                try_files $uri $uri/ =404;
        }
}

ERROR Executing the command cat /var/log/nginx/error.log gave me the following result:

EDIT-2

Executing chown -R nginx:nginx /var/www/sundaray.io/html threw the following error: enter image description here

EDIT-3

Executing ps -elf |grep nginx gave the following result:

EDIT-4 When I executed the command ls /var/www/sundaray.io/html, I got the following result: enter image description here

Solution

  • 1. chmod 777 is NEVER a good idea.

    NGINX operats under a runuser. How to check the runuser:

    ps -elf |grep nginx. Normaly it will be nginx. Instead of 777 (Open for everyone) do chmod -R 755 /path/to/folder and chown -R nginx:nginx /path/to/folder

    But agree. For troubleshooting it can be used. But back to your problem.

    2. Directory-Listing disabled.

    The error is telling you nginx can not list the directory content. Which is the default behavior. Make sure

    root /var/www/sundaray.io/html;

    This path exists AND

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

    there are one of these files located!

    Without any of these files NGINX can't load the default index file on /. Put something in /var/www/sundaray.io/html like

    printf "<html>\n<body>\n<h1>Hello from NGINX</h1>\n</body>\n</html>" > /var/www/sundaray.io/html/index.html && chown nginx:nginx /var/www/sundaray.io/html/index.html. This should generate an index.html for you.

    If you just want to test your server configuration without any files:

    location / {
  return 200 "Hello on $host$uri\n";
}
