NGINX + Let's encrypt：无法自动找到匹配的服务器块

Question

我正在 Ubuntu 18.04 服务器上发布一个使用 Python Pyramid 制作的网站。该网站在 HTTP 上正常运行，现在我试图通过关注 this article 使其在 HTTPS 上运行，但在尝试安装时我收到此消息：

IMPORTANT NOTES:
 - Unable to install the certificate
 - Congratulations! Your certificate and chain have been saved at:
   /etc/letsencrypt/live/dev.anything.com/fullchain.pem
   Your key file has been saved at:
   /etc/letsencrypt/live/dev.anything.com/privkey.pem
   Your cert will expire on 2019-03-17. To obtain a new or tweaked
   version of this certificate in the future, simply run certbot again
   with the "certonly" option. To non-interactively renew *all* of
   your certificates, run "certbot renew" 

这是我的配置文件，位于/etc/nginx/sites-available/snow_service.nginx:

server {
    listen 80;
    listen 443 ssl;
    server_name dev.anything.com
    server_tokens off;
    ssl_certificate /etc/letsencrypt/live/dev.anything.com/fullchain.pem;
    ssl_certificate_key /etc/letsencrypt/live/dev.anything.com/privkey.pem;

    charset utf-8;
    client_max_body_size 1M;

    location /static {
        gzip            on;
        gzip_buffers    8 256k;
        uwsgi_buffers   8 256k;

        alias /webapps/englobe_snow_pyramid_rest_api/pyramid_rest_api/static;
        expires 1d;
    }
    location / {
        gzip            on;
        gzip_buffers    8 256k;
        uwsgi_buffers   8 256k;

        try_files $uri @yourapplication;
    }
    location @yourapplication {
        gzip            on;
        gzip_buffers    8 256k;
        uwsgi_buffers   8 256k;

        server_tokens off;
        include uwsgi_params;
        proxy_set_header Host $host;
        proxy_set_header real_scheme $scheme;
        proxy_set_header X-Forwarded-Protocol $scheme;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_pass http://127.0.0.1:8999;
    }
}

我也尝试用域名重命名文件，但效果不佳。 我手动放置的 ssl 证书的路径，因为我在 Stack Overflow 的另一个答案中看到了它。

我错过了什么？感谢您的帮助

解决方法如下： 我正在更改sites-available 文件夹中的文件，而不是更改sites-enabled 文件夹中的文件。这是最终的文件内容：

server {
    listen 80 default_server;
    server_name dev.anything.com;
    return 301 https://$server_name$request_uri;
}

server {
    listen 443 ssl;
    server_name elglobe_snow_service
    server_tokens off;

    ssl_certificate /etc/letsencrypt/live/dev.anything.com/fullchain.pem;
    ssl_certificate_key /etc/letsencrypt/live/dev.anything.com/privkey.pem;

    charset utf-8;
    client_max_body_size 1M;

    location /static {
        gzip            on;
        gzip_buffers    8 256k;
        uwsgi_buffers   8 256k;

        alias /webapps/englobe_snow_pyramid_rest_api/pyramid_rest_api/static;
        expires 1d;
    }
    location / {
        gzip            on;
        gzip_buffers    8 256k;
        uwsgi_buffers   8 256k;

        try_files $uri @yourapplication;
    }
    location @yourapplication {
        gzip            on;
        gzip_buffers    8 256k;
        uwsgi_buffers   8 256k;

        server_tokens off;
        include uwsgi_params;
        proxy_set_header Host $host;
        proxy_set_header real_scheme $scheme;
        proxy_set_header X-Forwarded-Protocol $scheme;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_pass http://127.0.0.1:8999;
    }
}

sites-enabled 中的文件应该只是指向sites-available 中“真实”文件的链接。 您应该只编辑可用站点中的那些，然后运行

cd /etc/nginx/sites-enabled ln -s ../sites-available/your-site.conf

启用该网站。

如果您想禁用该站点，您只需删除启用站点中的链接即可。
