ubuntu - Nginx 将 www 域重定向到非 www

Question

我要www.example.app去 example.app 进行 SEO，我遵循了几个教程和问题解决方案，但似乎无法让它工作。
我添加了一个单独的服务器 block ，它重定向到非 www 域并多次重新启动 nginx，还从一个隐身窗口访问我的站点。
这是我的 /etc/nginx/sites-available/default配置文件。
任何帮助，将不胜感激!

server {
    server_name www.example.app;
    return 301 $scheme://example.app$request_uri;
}

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


    root /var/www/html/;

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

    server_name exampe.app;

    location / {
        try_files $uri $uri/ =404;
    }
    
    location ~*  \.(jpg|jpeg|png|gif|ico|css|js)$ {
            expires 365d;
        }

        location ~*  \.(pdf)$ {
            expires 30d;
        }

    location ~ \.php$ {
        include snippets/fastcgi-php.conf;
        fastcgi_pass unix:/var/run/php/php7.0-fpm.sock;
    }

    location ~ /\.ht {
     deny all;
    }

    error_page 404 /customerror_404.html;
    location = /customerror_404.html {
        root /usr/shar/nginx/html;
        internal;
    }
    
}


server {
    root /var/www/html/;
    index index.php index.html index.htm index.nginx-debian.html;
    server_name example.app; # managed by Certbot


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

    location ~ \.php$ {
        include snippets/fastcgi-php.conf;
        fastcgi_pass unix:/var/run/php/php7.0-fpm.sock;
    }

    location ~ /\.ht {
        deny all;
    }


    listen [::]:443 ssl ipv6only=on; # managed by Certbot
    listen 443 ssl; # managed by Certbot
    ssl_certificate /etc/letsencrypt/live/example.app/fullchain.pem; # managed by Certbot
    ssl_certificate_key /etc/letsencrypt/live/example.app/privkey.pem; # managed by Certbot
    include /etc/letsencrypt/options-ssl-nginx.conf; # managed by Certbot
    ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem; # managed by Certbot

}


server {
    if ($host = example.app) {
        return 301 https://$host$request_uri;
    } # managed by Certbot


    listen 80 ;
    listen [::]:80 ;
    server_name example.app;
    return 404; # managed by Certbot

}

Answer 1

server {
    if ($host = www.example.app) {
        return 301 https://$host$request_uri;
    } # managed by Certbot


    listen 80 ;
    listen [::]:80 ;
    server_name example.app;
    return 404; # managed by Certbot

}

我使用它从 www 域重定向到非 www 域。
在这种情况下，您需要告诉 nginx 是否要从 www 重定向的主机。
如果这不起作用。您可能需要将服务器名称设置为这样

server_name www.example.app example.app;

这样主机就被认出来了。
