nginx: [warn] conflicting server name "" on 0.0.0.0:80, ignored

Time：10-31

I have three nginx server blocks and when i run nginx -t get error "nginx: [warn] conflicting server name "" on 0.0.0.0:80, ignored"

I have three nginx server blocks:

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

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

        root /var/www/html;

        server_name _;

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

}

Two: /etc/nginx/sites-available/example.com

server {
    listen         80;
    return 301 https://$host$request_uri;
}
server {
# Document Root

When i run: $ sudo nginx -t

This answer appears:

nginx: [warn] conflicting server name "" on 0.0.0.0:80, ignored

How do i solve this?

CodePudding user response：

example.com and example1.com both are identical, you have to add server_name on the listen 80 of both blocks.

Corrected Server blocks is:

Two: /etc/nginx/sites-available/example.com

server {
    listen         80;
    server_name .example.com;
    return 301 https://example.com$request_uri;
}
server {
# Document Root
root /var/www/example.com;
index index.php index.html index.htm;
server_name .example.com;
client_max_body_size 0;

    listen [::]:443 ssl http2 ipv6only=on;
    listen 443 ssl http2;
        ssl_protocols TLSv1.1 TLSv1.2 TLSv1.3;
        ssl_certificate /etc/letsencrypt/live/example.com/fullchain.pem;
        ssl_certificate_key /etc/letsencrypt/live/example.com/privkey.pem;
        ssl_prefer_server_ciphers on;
        ssl_session_cache   shared:SSL:20m;
        ssl_session_timeout 20m;
        ssl_ciphers 'TLS13 AESGCM AES128:EECDH AES128';
