昨天，我能看到默认页面就像你看到的这里

Yesterday I was able to see default page like you see here.

不过今天我修改配置的nginx的访问是在麒麟运行我的Rails应用程序，并开始渐渐404。

But today I modified config for nginx to access my rails application which is running on unicorn and started getting 404.

/etc/nginx/nginx.conf

user www-data;
worker_processes 4;
pid /var/run/nginx.pid;

events {
  worker_connections 768;
  # multi_accept on;
}

http {
  ##
  # Basic Settings
  ##

  sendfile on;
  tcp_nopush on;
  tcp_nodelay on;
  keepalive_timeout 65;
  types_hash_max_size 2048;

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

  ##
  # Logging Settings
  ##

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

  ##
  # Gzip Settings
  ##

  gzip on;
  gzip_disable "msie6";

  ##
  # Virtual Host Configs
  ##

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

end][2]

我也验证了连接到EC2安全组允许22，80和443端口。请找连接安全规则的EC2。

I also verified that the security groups attached to EC2 allows 22, 80 and 443 ports. Please find attached security rules for EC2.

我重新启动nginx的和麒麟多次证实nginx的和麒麟运行正常。

I restarted nginx and unicorn many times and verified that nginx and unicorn are running properly.

我也验证了nginx的访问和错误日​​志，但无法看到任何在那里的活动。

I also verified nginx access and error logs but could not see any activity there.

请帮忙，

最后我能解决这个问题。这个问题是AWS的期待，使nginx的SSL的。

Finally I am able to fix it. The issue was AWS was expecting to make nginx SSL aware.

因此​​，为了使工作我创建自签名证书并修改nginx的配置。下面是最终配置。

So to make it work I created self signed certificate and modify nginx configuration. Below is the final configuration.

upstream integrity_matters_server {
  server unix:/tmp/unicorn.integrity_matters.sock fail_timeout=0;
}

server {
  listen   80;
  server_name ec2-52-10-245-227.us-west-2.compute.amazonaws.com;
  rewrite ^/(.*) https://ec2-52-10-245-227.us-west-2.compute.amazonaws.com permanent;
}

server {
  listen   443;
  server_name ec2-52-10-245-227.us-west-2.compute.amazonaws.com;
  root /home/ubuntu/integrity_matters/current/public;

  ssl on;
  ssl_certificate      /etc/nginx/ssl/nginx_im.crt;
  ssl_certificate_key  /etc/nginx/ssl/nginx_im.key;
  ssl_protocols        SSLv3 TLSv1;
  ssl_prefer_server_ciphers on;

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

  try_files $uri @integrity_matters;
  location @integrity_matters {
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header X-Forwarded-Proto https;
    proxy_set_header Host $host;
    proxy_redirect off;
    proxy_pass http://integrity_matters_server;
  }

  error_page 500 502 503 504 /500.html;
  client_max_body_size 20M;
  keepalive_timeout 10;
}

这post而我们做的SSL配置也非常有用。

This post also useful while we were making SSL configuration.
