参考： https://github.com/80percent/rails-template/blob/master/files/config/nginx.conf.example ，这是个 http 的配置，https 的自己再搜一下吧，很简单。拿去不谢

@rina 我这是想要实现 https 和 http 都可以访问的情况，http 我可以配置

#2 楼 @starshine rewrite all http requests to https #9373

说清楚，你的问题是什么！！！

整理好你贴上来的 Nginx 配置信息

分别：

listen 443 ssl;

listen 80;

但是你的 http 里面是跳转成 https。

还有 根据你 ssl 证书的要求修改一下支持的协议和加密算法

ssl on;
ssl_certificate /opt/zs/33iq.crt;
ssl_certificate_key /opt/zs/33iq.key;
ssl_session_timeout 5m;
ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
ssl_ciphers  ECDHE-RSA-AES128-GCM-SHA256:ECDHE:HIGH:!aNULL:!MD5:!ADH:!DH;
ssl_prefer_server_ciphers on;

你配置文件贴的不全吧。

楼主参考这个网页的设置，关键点是 proxy_set_header X-Forwarded-Proto https; https://www.digitalocean.com/community/questions/error-too-many-redirect-on-nginx

I just had the exact same problem after enabling SSL. The issue for me was I have Rails set to config.force_ssl = true which relies on the proxy_set_header X-Forwarded-Proto https; header to know whether the request was over SSL or not. I didn't have that header to Rails would receive an SSL request thinking it wasn't with SSL which caused it to redirect to https.

Here's my working config:

upstream puma {
  server unix:///home/deploy/apps/genus/shared/tmp/sockets/genus-puma.sock;
}

server {
  listen 80;
  listen 443 ssl;
  server_name genusapp.com;

  ssl_certificate /home/deploy/apps/genus/genusapp_com.pem;
  ssl_certificate_key /home/deploy/apps/genus/genusapp_com.key;
  ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
  ssl_prefer_server_ciphers on;
  ssl_ciphers AES256+EECDH:AES256+EDH:!aNULL;


  root /home/deploy/apps/genus/current/public;
  access_log /home/deploy/apps/genus/current/log/nginx.access.log;
  error_log /home/deploy/apps/genus/current/log/nginx.error.log info;

  location ^~ /assets/ {
    gzip_static on;
    expires max;
    add_header Cache-Control public;
  }

  try_files $uri/index.html $uri @puma;
  location @puma {
    proxy_set_header X-Forwarded-Proto https;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header Host $http_host;
    proxy_redirect off;

    proxy_pass http://puma;
  }

  error_page 500 502 503 504 /500.html;
  client_max_body_size 10M;
  keepalive_timeout 10;
}

我是参考这个配置解决的。https://www.digitalocean.com/community/questions/error-too-many-redirect-on-nginx

@jiyuhang110 我没有使用 80 默认端口，而是适用的是 其他的端口 监听

@sandy_xu 谢谢 回复，我的配置如果不使用 默认 80 端口，而是使用 其他的端口进行监听，怎么办？

#9 楼 @starshine 非 80 端口不清楚。不过我知道你的配置肯定缺少 proxy_set_header X-Forwarded-Proto https，楼主多尝试，成功后求分享经验
