nginx：[emerg]此处不允许使用“index”指令

我尝试过 nginx -t并且一切看起来都正确。

我收到此错误：

nginx -c /etc/nginx/sites-available/premonstrati2021.cz -T
nginx: [emerg] "index" directive is not allowed here in /etc/nginx/sites-available/premonstrati2021.cz:1
nginx: configuration file /etc/nginx/sites-available/premonstrati2021.cz test failed

我的配置文件是这样的：

index   index.html index.htm;

server {
        listen 80;
        listen [::]:80;
        server_name premonstrati2021.cz;

        #port_in_redirect off;
        #proxy_set_header Host $host:$server_port;

#       if ($scheme != "https") {
#               return 301 https://$host$request_uri;
#       }
        return 301 https://$host$request_uri;
}

server {
        listen       443 ssl http2;
        listen       [::]:443 ssl http2;

        }

       location /widget {
               root /var/www/html/app/widget;

               if ($request_method = 'GET') {
                        add_header 'Access-Control-Allow-Origin' '*';
                        add_header 'Access-Control-Allow-Methods' 'GET, POST, OPTIONS';
                        add_header 'Access-Control-Allow-Headers' 'DNT,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type,Range';
                        add_header 'Access-Control-Expose-Headers' 'Content-Length,Content-Range';
                }
       }
}

server {
   listen 443;
   server_name www.premonstrati2021.cz;
   return 301 https://$server_name$request_uri;
}

我无法重新启动 nginx，因为出现错误，但我找不到任何错误。我刚刚添加了带有 location /widget { ... } 的块。我试图删除它，但没有成功。你有什么想法吗？

该指令index index.html index.htm;应该放在上下文内部server {}，但是你却把它放在任何之外server。

将其移至适当的上下文，例如：

server {
        listen 80;
        listen [::]:80;
        server_name premonstrati2021.cz;

        index   index.html index.htm;

        #port_in_redirect off;
        #proxy_set_header Host $host:$server_port;

#       if ($scheme != "https") {
#               return 301 https://$host$request_uri;
#       }
        return 301 https://$host$request_uri;
}

server {
        listen       443 ssl http2;
        listen       [::]:443 ssl http2;

        root /var/www/html/app/dist;

        server_name  premonstrati2021.cz www.premonstrati2021.cz;

        ssl_dhparam /etc/nginx/dhparam.pem
        ssl_certificate "/etc/letsencrypt/live/premonstrati2021.cz/cert.pem";
        ssl_certificate_key "/etc/letsencrypt/live/premonstrati2021.cz/privkey.pem";
        ssl_verify_client      optional;
        ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
        ssl_ciphers 'ECDHE-ECDSA-CHACHA20-POLY1305:ECDHE-RSA-CHACHA20-POLY1305:ECDHE-ECDSA-AES128-GCM-SHA256:ECDHE-RSA-AES128-GCM-SHA256:ECDHE$

        access_log  /var/log/nginx/log/premonstrati.access.log  main;
        error_log  /var/log/nginx/log/premonstrati.com.br.error.log;

        port_in_redirect off;
        proxy_set_header Host $host:$server_port;

        location /api {
                proxy_set_header X-Real-IP $remote_addr;
                proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

                proxy_pass https://127.0.0.1:3000/api;
                proxy_ssl_server_name on;

                proxy_next_upstream error timeout invalid_header http_500 http_502 http_503 http_504;
                proxy_buffering off;
                proxy_set_header  Host  $host;
                proxy_set_header  X-Real-IP   $remote_addr;
                proxy_set_header  X-Forwarded-For   $proxy_add_x_forwarded_for;
        }

       location /widget {
               root /var/www/html/app/widget;

               if ($request_method = 'GET') {
                        add_header 'Access-Control-Allow-Origin' '*';
                        add_header 'Access-Control-Allow-Methods' 'GET, POST, OPTIONS';
                        add_header 'Access-Control-Allow-Headers' 'DNT,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type,Range';
                        add_header 'Access-Control-Expose-Headers' 'Content-Length,Content-Range';
                }
       }
}

server {
   listen 443;
   server_name www.premonstrati2021.cz;
   return 301 https://$server_name$request_uri;
}

您需要创建一个从文件/etc/nginx/sites-available/premonstrati2021.cz到的符号链接，/etc/nginx/sites-enabled/premonstrati2021.cz以便 nginx 实际使用您的配置。

目前，您的配置位于 下的文件中sites-available，但 nginx 不包含该文件中的文件。

另外，这个块是错误的：

server {
    listen 443;
    server_name www.premonstrati2021.cz;
    return 301 https://$server_name$request_uri;
}

这会导致无限的 301 重定向循环。由于 已存在阻止server，因此www.premonstrati2021.cz您只需删除此阻止即可。
