Nginx 非 www 重定向到 www 怎么解决？

这是我的 NGinx Web 服务器配置

    server {
        if ($host ~ ^[^.]+\.betafox\.net$) {
            return 301 https://$host$request_uri;
        } # managed by Certbot
    
    
        if ($host = www.betafox.net) {
            return 301 https://$host$request_uri;
        } # managed by Certbot
    
    
        if ($host = betafox.net) {
            return 301 https://$host$request_uri; 
        } # managed by Certbot
    
        listen 80;
        listen [::]:80;
    
        #server_name _;
        root /var/www/html;
    
    server_name betafox.net *.betafox.net;
        #return 301 https://$host$request_uri;
        index index.php index.html index.htm;
        location / {
            # try_files $uri $uri/ =404;
            try_files $uri $uri/ /index.php?q=$uri&$args;
            proxy_pass  https://betafox.net/;
            proxy_redirect  https://betafox.net/ $host;
            proxy_set_header Accept-Encoding "";
            proxy_ssl_server_name on;
        }
        location ~ \.php$ {
            include snippets/fastcgi-php.conf;
            #fastcgi_pass 127.0.0.1:9000;
            #fastcgi_pass unix:/run/php/php8.0-fpm.sock;
            fastcgi_pass unix:/etc/alternatives/php-fpm.sock;
     }
    
    
    }
    
    server {
    
    listen 443 ssl default_server;
            listen [::]:443 ssl default_server;
    
            root /var/www/html;
            index index.php index.html index.htm;
    
          # server_name _;
            server_name betafox.net *.betafox.net;
            # Maximum file upload size is 4MB - change accordingly if needed
            client_max_body_size 512M;
            client_body_buffer_size 128k;
            include snippets/letsencrypt-nginx-certs.conf;
            include snippets/letsencrypt-nginx-route.conf;
    
            location / {
                    # try_files $uri $uri/ =404;
                    try_files $uri $uri/ /index.php?q=$uri&$args;
            }
    error_page 404 /404.html;
    
            error_page 500 502 503 504 /50x.html;
            location = /50x.html {
                    root /usr/share/nginx/html;
            }
    
            location ~ \.php$ {
                    include snippets/fastcgi-php.conf;
                    #fastcgi_pass 127.0.0.1:9000;
                    #fastcgi_pass unix:/var/run/php8.0-fpm.sock;
                    fastcgi_pass unix:/etc/alternatives/php-fpm.sock;
            }
        ssl_certificate /etc/letsencrypt/live/betafox.net-0001/fullchain.pem; # managed by Certbot
        ssl_certificate_key /etc/letsencrypt/live/betafox.net-0001/privkey.pem; # managed by Certbot
    
    }

当我为 FQDN 和子域安装 SSL 证书时，Certbot 自动修改了大部分内容。我面临的问题与 URL 重定向有关。原始 URL 是www.betafox.net，当用户输入 betafox.net 时，会重定向到https://betafoxnet.www.betafox.net/并显示一条消息：您正在寻找的站点不存在。

我只希望所有输入 betafox.net 的用户都被转发到www.betafox.net我相信 Nginx 可以做到这一点。我该如何实现这样的事情？

if不幸的是，Certbot 使用有问题的变量创建了 nginx 重定向$host。

最好将重定向放在单独的server部分中，如下所示。

# Redirect all requests to betafox.net URLs to corresponding www.betafox.net URLs
server {
    listen 80;
    listen 443 ssl http2;

    ssl_certificate /etc/letsencrypt/live/betafox.net-0001/fullchain.pem; # managed by Certbot
    ssl_certificate_key /etc/letsencrypt/live/betafox.net-0001/privkey.pem; # managed by Certbot

    server_name betafox.net;

    return 301 https://www.betafox.net$request_uri;
}

# Redirect all other subdomain HTTP requests to HTTPS.
server {
    listen 80;

    server_name *.betafox.net;

    return 301 https://$http_host$request_uri;:
}

# Removed the server block for port 80, it looked meaningless

server {
    # Removed the default_server, default_server should not be the actual website
    listen 443 ssl;
    listen [::]:443 ssl;

    root /var/www/html;
    index index.php index.html index.htm;

    server_name betafox.net *.betafox.net;
    # Maximum file upload size is 4MB - change accordingly if needed
    client_max_body_size 512M;
    client_body_buffer_size 128k;
    include snippets/letsencrypt-nginx-certs.conf;
    include snippets/letsencrypt-nginx-route.conf;

    location / {
        try_files $uri $uri/ /index.php?q=$uri&$args;
    }
    error_page 404 /404.html;

    error_page 500 502 503 504 /50x.html;
    location = /50x.html {
        root /usr/share/nginx/html;
    }

    location ~ \.php$ {
        include snippets/fastcgi-php.conf;
        fastcgi_pass unix:/etc/alternatives/php-fpm.sock;
    }
    ssl_certificate /etc/letsencrypt/live/betafox.net-0001/fullchain.pem; # managed by Certbot
    ssl_certificate_key /etc/letsencrypt/live/betafox.net-0001/privkey.pem; # managed by Certbot
}
