Nginx: Should I choose default or mydomain.conf configuration to serve a single domain in a server?

I am new Nginx. Currently, I configured my domain to be served by Nginx on the default configuration as follows and it is working.

sudo nano /etc/nginx/sites-available/default

Default configuration:

server {
    listen        80;
    server_name   uidcenterkl.my *.uidcenterkl.my;
    location / {
        proxy_pass http://localhost:5000;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection keep-alive;
        proxy_set_header Host $host;
        proxy_cache_bypass $http_upgrade;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;
    }
}

However, I learnt that I need to create domain specific directive such as mywebiste.com.conf as follows:

sudo nano /etc/nginx/sites-available/mywebiste.com.conf

Question:

What should I choose, default or mywesbite.com.conf to serve a single domain? And if I went with mywebsite.com.conf, how to deactivate default configuration so that it does not cause conflict.

>Solution :

You may actually not need to set up domain specific directive to serve a single domain. `default directive should work fine for you.

And if you choose to use mywesbite.com.conf, all you need to do to disable default is to delete it from inside sites-enabled directory

After creating your mywesbite.com.conf feel free to delete the default.conf by running this command from your sites-enabled dirctory:

sudo rm ../sites-enabled/default.conf

Don’t forget to restart your nginx after that command

systemctl restart nginx
