Question

我正在使用AWS EC2与Nginx和Puma构建一个测试应用程序，遵循本教程

https://www.sitepoint.com/deploy-your-rails-app-to-aws/

我也可以使用Capistrano成功部署该应用。该应用程序也适用于开发。我在开发和生产中使用Rails 5和Ruby 2.3.1。

目前，我有两页正在开发但尚未投入生产。

使用此网址时的制作

http://ec2-54-226-156-103.compute-1.amazonaws.com/

我正在

This is the default index.html page that is distributed with nginx on the Amazon Linux AMI. It is located in /usr/share/nginx/html.

而不是我的主页。

当我使用此网址时

http://ec2-54-226-156-103.compute-1.amazonaws.com/contacts

我正在

nginx error!
The page you are looking for is not found.
Something has triggered missing webpage on your website. This is the default 404 error page for nginx that is distributed with the Amazon Linux AMI. It is located at /usr/share/nginx/html/404.html
You should customize this error page for your own site or edit the error_page directive in the nginx configuration file /etc/nginx/nginx.conf.

不知道如何解决这个问题。

以下是我的Nginx配置文件。

和

}

  server_name localhost;

  root /home/deploy/contactbook/public;

  try_files $uri/index.html $uri @app;

  location / {

    proxy_redirect off;
    proxy_http_version 1.1;
    proxy_set_header Connection '';
    proxy_pass http://app;
  }

  location ~ ^/(assets|fonts|system)/|favicon.ico|robots.txt {
    gzip_static on;
    expires max;
    add_header Cache-Control public;
  }

  error_page 500 502 503 504 /500.html;
  client_max_body_size 4G;
  keepalive_timeout 10;
}

不知道如何修复这些Nginx设置以使应用程序正常运行并且Nginx从应用程序提供页面？

如果这可能有任何帮助，这里是文件夹/ home / deploy / contactbook / shared中的puma配置文件

cat puma.rb

#!/usr/bin/env puma

directory '/home/deploy/contactbook/current'
rackup "/home/deploy/contactbook/current/config.ru"
environment 'production'

pidfile "/home/deploy/contactbook/shared/tmp/pids/puma.pid"
state_path "/home/deploy/contactbook/shared/tmp/pids/puma.state"
stdout_redirect '/home/deploy/contactbook/shared/log/puma_error.log', '/home/deploy/contactbook/shared/log/puma_access.log', true

threads 0,8

bind 'unix:///home/deploy/contactbook/shared/tmp/sockets/puma.sock'

workers 0

prune_bundler

on_restart do
  puts 'Refreshing Gemfile'
  ENV["BUNDLE_GEMFILE"] = "/home/deploy/contactbook/current/Gemfile"
end

Answer 1

问题在于网站可用/默认为server_name localhost;。

我的意思是nginx只会将该服务器块用于Host头与“localhost”匹配的请求对于测试，您可以将其设置为server_name _;，这是全能的。

最终，您需要将其设置为您的网站名称，例如server_name ec2-54-226-156-103.compute-1.amazonaws.com，但这可以等到您拥有域名。

Answer 2

某些原因导致您网站上的网页丢失。这是随 Red Hat Enterprise Linux 分发的 nginx 的默认 404 错误页面。它位于 /usr/share/nginx/html/404.html

您应该为自己的站点自定义此错误页面或编辑 nginx 配置文件 /etc/nginx/nginx.conf 中的 error_page 指令。

有关 Red Hat Enterprise Linux 的信息，请访问 Red Hat, Inc. 网站。 Red Hat Enterprise Linux 文档可在 Red Hat, Inc. 网站上找到。
