如何正确地为一个单一域下具有多个端口/服务的nginx服务器设置Certbot？

Question

最初，我将NGINX配置为两个不同端口上的两个服务(激进和LMS)。这是我在/etc/nginx/nginx.conf做的。从互联网访问MYDOMAIN:8000、:8009和3001分别重定向到Radicale和LMS。

我在服务器上设置了证书来启用它，然后运行sudo certbot --nginx -d MYDOMAIN来生成letsencrypt。之后，我禁用了自己的证书(我只需设置它们以使配置文件没有错误)。

user www-data;
worker_processes auto;
pid /run/nginx.pid;
include /etc/nginx/modules-enabled/*.conf;

events {
    worker_connections 768;
}

http {
    sendfile on;

    tcp_nopush on;
    types_hash_max_size 2048;
    keepalive_timeout 65;

    include /etc/nginx/mime.types;
    default_type application/octet-stream;

    ssl_protocols TLSv1 TLSv1.1 TLSv1.2 TLSv1.3; # Dropping SSLv3, ref: POODLE
    ssl_prefer_server_ciphers on;

    # reduce logging
    access_log off;

#   access_log /var/log/nginx/access.log;
    error_log /var/log/nginx/error.log;

    gzip on;

#   include /etc/nginx/conf.d/*.conf;
#   include /etc/nginx/sites-enabled/*;

    auth_basic "NGINX";
    auth_basic_user_file /etc/nginx/.htpasswd;

#   old, before Certbot
#   ssl_certificate ssl/server.crt;
#   ssl_certificate_key ssl/server.key;
    
    server {
      server_name MYDOMAIN;
      listen 8000 ssl;
      location / {
        proxy_pass http://localhost:8000;
        proxy_set_header X-Script-Name /;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Remote-User $remote_user;
        proxy_set_header Host $http_host;
        proxy_pass_header Authorization;
        auth_basic "Nginx-Radicale - Password required";
      }
    
    # generated with: sudo certbot --nginx -d MYDOMAIN
    ssl_certificate /etc/letsencrypt/live/MYDOMAIN/fullchain.pem; # managed by Certbot
    ssl_certificate_key /etc/letsencrypt/live/MYDOMAIN/privkey.pem; # managed by Certbot
}
    server {
      server_name MYDOMAIN;
      listen 8009;
      return 301 https://MYDOMAIN:3001;
    }
    server {
      server_name MYDOMAIN;
      listen 3001;
      location / {
        proxy_pass http://localhost:3000/;
        auth_basic "NGINX";
      }
    }
}

现在，我更改了我的安装程序，并希望将配置的server部分拆分到nginx/conf.d子目录中，以获得一个干净的设置。我想让原始的nginx.conf在它来的时候，只调整我自己的两个文件：

pi@RPi64:/etc/nginx $ cat conf.d/radicale.conf 
server {
  server_name MYDOMAIN;
  listen 8000; 
# ssl;
  location / {
    proxy_pass http://localhost:5232;
    proxy_set_header X-Script-Name /;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header X-Remote-User $remote_user;
    proxy_set_header Host $http_host;
    proxy_pass_header Authorization;
    auth_basic "Nginx-Radicale - Password required";
  }
}

第二份文件：

pi@RPi64:/etc/nginx $ cat conf.d/LMS.conf
server {
    server_name MYDOMAIN;
    listen 8009;
    return 301 https://MYDOMAIN:3001;

    listen 443 ssl; # managed by Certbot
    ssl_certificate /etc/letsencrypt/live/MYDMOAIN/fullchain.pem; # managed by Certbot
    ssl_certificate_key /etc/letsencrypt/live/MYDOMAIN/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 {
    server_name MYDOMAIN;
    listen 3001;
    location / {
        proxy_pass http://localhost:3000/;
        auth_basic "NGINX";
    }
}

如您所见，我在第一个文件中注释掉了ssl部件。如果我让它进入sudo nginx -t，就会产生丢失证书的错误。我想避免设置我自己的证书。

另外，您可以看到运行certbot在我的第二个文件中添加了五行：

    listen 443 ssl; # managed by Certbot
    ssl_certificate /etc/letsencrypt/live/MYDMOAIN/fullchain.pem; # managed by Certbot
    ssl_certificate_key /etc/letsencrypt/live/MYDOMAIN/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

我认为certbot在这个文件中找到了https，然后决定在那里添加证书。

但是，我想为整个服务器添加证书--这意味着两个站点/文件。

特别是由于更新证书的过程必须定期进行，我想确保没有涉及手动复制。

How我可以告诉 Certbot两个文件的to插入证书吗？是否必须首先添加自己的证书才能识别请求？

或者将证书添加到主nginx.conf文件中是否有意义？我做错什么了吗？

我的解决方案是在nginx.conf中添加以下内容：

server {
    server_name MYDOMAIN
    listen 443; 
}

编辑:当然，也可以将此服务器作为.conf添加到conf.d中。这样处理起来就容易了。

然后运行certbot --nginx -d MYDOMAIN，将以下行放入其中：

    listen 443 ssl; # managed by Certbot
    ssl_certificate /etc/letsencrypt/live/MYDOMAIN/fullchain.pem; # managed by Certbot
    ssl_certificate_key /etc/letsencrypt/live/MYDOMAIN/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 ($host = MYDOMAIN) {
        return 301 https://$host$request_uri;
    } # managed by Certbot


        server_name MYDOMAIN
        listen 443;
    listen 80;
    return 404; # managed by Certbot

然后，我删除了这些行，并将此部分放入我的conf.d/中的每个文件中。

    ssl_certificate /etc/letsencrypt/live/MYDOMAIN/fullchain.pem; # managed by Certbot
    ssl_certificate_key /etc/letsencrypt/live/MYDOMAIN/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

我认为更新过程将只考虑/etc/letsencrypt的证书本身，因此conf.d中的手动修复应该是可以的。
