两个 node.js 域在同一个 nginx 服务器上使用 SSL - 443 的重复侦听选项

Question

我已经在我的 DigitalOcean Droplet 中设置了两个 Web 应用程序，我正在尝试运行这两个应用程序在不同的域上，使用 SSL 加密。

如果我只使用其中一个域，我可以确认一切正常，当我尝试同时运行两个域时出现错误。

nginx -t
duplicate listen options for [::]:443 in /etc/nginx/sites-enabled/hello.com:26

/etc/nginx/sites-avilable/hello.com

server {
    server_name hello.com www.hello.com;

    location / {
            proxy_pass http://localhost:4000;
            proxy_http_version 1.1;
            proxy_set_header Upgrade $http_upgrade;
            proxy_set_header Connection 'upgrade';
            proxy_set_header Host $host;
            proxy_cache_bypass $http_upgrade;
    }

    listen [::]:443 ssl ipv6only=on default_server; # managed by Certbot
    listen 443 ssl default_server; # managed by Certbot
    ssl_certificate /etc/letsencrypt/live/hello.com/fullchain.pem; # managed by Certbot
    ssl_certificate_key /etc/letsencrypt/live/hello.com/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 ($host = www.hello.com) {
                return 301 https://$host$request_uri;
        } # managed by Certbot


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


    listen 80 default_server;
    listen [::]:80 default_server;

    server_name hello.com www.hello.com;
    return 404; # managed by Certbot
}

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

server {
    server_name example.com www.example.com;

    location / {
            proxy_pass http://localhost:3000;
            proxy_http_version 1.1;
            proxy_set_header Upgrade $http_upgrade;
            proxy_set_header Connection 'upgrade';
            proxy_set_header Host $host;
            proxy_cache_bypass $http_upgrade;
    }

    listen [::]:443 ssl ipv6only=on; # managed by Certbot
    listen 443 ssl; # managed by Certbot
    ssl_certificate /etc/letsencrypt/live/example.com/fullchain.pem; # managed by Certbot
    ssl_certificate_key /etc/letsencrypt/live/example.com/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 ($host = www.example.com) {
                return 301 https://$host$request_uri;
        } # managed by Certbot


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


    listen 80;
    listen [::]:80;

    server_name example.com www.example.com;
    return 404; # managed by Certbot
}

我该怎么做才能避免这个错误？非常感谢对 nginx 文件的进一步改进。

我使用了以下指南：

问题是ipv6only=on，只能指定一次according to the documentation。

无论如何默认值为on，因此可以安全地删除该选项。
