Why is this NGINX config file invalid?-CodePudding

So I have this NGINX config file:

events { }
http {
    server {
        listen 443 ssl;
        ssl_certificate /home/dietpi/certs/cert.pem;
        ssl_certificate_key /home/dietpi/certs/privkey.pem.key;
        location / {
            proxy_set_header   X-Real-IP $remote_addr;
            proxy_set_header   X-Forwarded-For $proxy_add_x_forwarded_for;
            proxy_pass         http://localhost:3001/;
            proxy_http_version 1.1;
            proxy_set_header   Upgrade $http_upgrade;
            proxy_set_header   Connection "upgrade";
        }
    }
}

It is a reverse-proxy for a Docker container. It does SSL for me. I wanted to redirect HTTP to HTTPS, so I tried adding this:

events { }
http {
    server {
        listen 80 default_server;
        server _;
        return 301 https://$host$request_uri;
    }
    server {
        listen 443 ssl;
        ssl_certificate /home/dietpi/certs/cert.pem;
        ssl_certificate_key /home/dietpi/certs/privkey.pem.key;
        location / {
            proxy_set_header   X-Real-IP $remote_addr;
            proxy_set_header   X-Forwarded-For $proxy_add_x_forwarded_for;
            proxy_pass         http://localhost:3001/;
            proxy_http_version 1.1;
            proxy_set_header   Upgrade $http_upgrade;
            proxy_set_header   Connection "upgrade";
        }
    }
}

But now it doesn't work (sudo nginx -t fails). It says this:

nginx: [emerg] "server" directive is not allowed here in /etc/nginx/nginx.conf:5
nginx: configuration file /etc/nginx/nginx.conf test failed

Most people that have this error tend to have the server block not in an http block, and putting it in one fixes it. But... my server block is already in an http block. So how do I fix it?

CodePudding user response：

Typo is server instead of server_name within the server {} block

server {
  listen 80 default_server;
  server_name _;   # ✅ corrected
}
