Question

我有一个运行在https://localhost:8080中的node.js应用程序，它具有localhost.crt和localhost.key，我希望将nginx重定向到https://app.example.com的服务器（我已经安装了另一个证书在此子域上使用certbot）现在即时获取

未知ALPN协议，预期h2可用。如果这是HTTP请求：未为服务器配置allowHTTP1选项或unknownProtocol事件的侦听器。

在浏览器中，有人可以帮助我进行正确的Nginx服务器配置吗？ Screenshot 我也在Ubuntu 16.04上使用Digitalocean Droplet来设置它这是我设置的Nginx服务器。

server {
listen 80;
return 301 https://$host$request_uri;
}

server {

listen 443;
server_name app.mydomain.com;

ssl_certificate           /root/apps/app.mydomain.com/localhost.crt;
ssl_certificate_key       /root/apps/app.mydomain.com/localhost.key;

ssl on;
ssl_session_cache  builtin:1000  shared:SSL:10m;
ssl_protocols  TLSv1 TLSv1.1 TLSv1.2;
ssl_ciphers HIGH:!aNULL:!eNULL:!EXPORT:!CAMELLIA:!DES:!MD5:!PSK:!RC4;
ssl_prefer_server_ciphers on;

access_log            /var/log/nginx/app.access.log;

location / {

  proxy_set_header        Host $host;
  proxy_set_header        X-Real-IP $remote_addr;
  proxy_set_header        X-Forwarded-For $proxy_add_x_forwarded_for;
  proxy_set_header        X-Forwarded-Proto $scheme;

  # Fix the “It appears that your reverse proxy set up is broken" error.
  proxy_pass          https://localhost:8080;
  proxy_read_timeout  90;

  proxy_redirect      https://localhost:8080 https://app.mydomain.com;
}
}

Answer 1

此：

listen 443;

应该是这样

listen 443 ssl;

为什么要通过https将流量代理到127.0.0.1？似乎不必要

Answer 2

尝试此配置，希望它能起作用。并非所有标头都是必需的，它取决于您的应用程序需求以及如何为应用程序处理请求。

server {
listen 80;
return 301 https://$host$request_uri;
}

server {
listen 443;
server_name app.mydomain.com;

ssl on;
ssl_certificate_key       /root/apps/app.mydomain.com/localhost.key;
ssl_certificate           /root/apps/app.mydomain.com/localhost.crt;
ssl_session_cache  builtin:1000  shared:SSL:10m;
ssl_protocols  TLSv1 TLSv1.1 TLSv1.2;
ssl_ciphers HIGH:!aNULL:!eNULL:!EXPORT:!CAMELLIA:!DES:!MD5:!PSK:!RC4;
ssl_prefer_server_ciphers on;

access_log            /var/log/nginx/app.access.log;

location / {
    proxy_set_header        Host $host;
    proxy_pass          http://localhost:8080/;
    proxy_set_header        X-Real-IP $remote_addr;
    proxy_set_header        X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header        X-Forwarded-Proto $scheme;

    proxy_read_timeout  90;
    proxy_buffer_size   128k;
    proxy_buffers   4 256k; 
    proxy_busy_buffers_size 256k;
    proxy_temp_file_write_size 256k;
    proxy_connect_timeout 300s;
}
}
