ruby-on-rails - 部署后我看到标准 nginx 的 "It works!"

Question

我已经将带有 Capistrano 的 Rails 应用程序部署到 VPS，当我尝试使用“APP_NAME.com”访问它时，我看到标准 Nginx 的“它有效!”页。

我试图删除 index.html文件来自 /var/www文件夹，现在我看到其中的文件夹:apps , log和 tmp .

在 nginx.conf我有:

user nginx web;

pid /var/run/nginx.pid;
error_log /var/www/log/nginx.error.log;

events {
  worker_connections 1024;
  accept_mutex off;
  use epoll;
}

http {
  include mime.types;
  types_hash_max_size 2048;
  server_names_hash_bucket_size 64;
  default_type application/octet-stream;
  access_log /var/www/log/nginx.access.log combined;
  sendfile on;
  tcp_nopush on; # off may be better for *some* Comet/long-poll stuff
  tcp_nodelay off; # on may be better for some Comet/long-poll stuff

  gzip on;
  gzip_http_version 1.0;
  gzip_proxied any;
  gzip_min_length 0;
  gzip_vary on;
  gzip_disable "MSIE [1-6]\.";
  gzip_proxied expired no-cache no-store private auth;
  gzip_comp_level 9;
  gzip_types text/plain text/xml text/css
             text/comma-separated-values
             text/javascript application/x-javascript
             application/atom+xml;

  upstream app_server {
    server unix:/var/www/apps/APP_NAME/socket/.unicorn.sock fail_timeout=0;
  }

  server {

    pagespeed on;
    pagespeed FileCachePath /var/ngx_pagespeed_cache;

    location ~ "\.pagespeed\.([a-z]\.)?[a-z]{2}\.[^.]{10}\.[^.]+" {
      add_header "" "";
    }

    location ~ "^/ngx_pagespeed_static/" { }
    location ~ "^/ngx_pagespeed_beacon$" { }

    location /ngx_pagespeed_statistics {
      allow 127.0.0.1; allow 5.228.169.73; deny all;
    }

    location /ngx_pagespeed_global_statistics {
      allow 127.0.0.1; allow 5.228.169.73; deny all;
    }

    pagespeed MessageBufferSize 100000;

    location /ngx_pagespeed_message {
      allow 127.0.0.1; allow 5.228.169.73; deny all;
    }

    location /pagespeed_console {
      allow 127.0.0.1; allow 5.228.169.73; deny all;
    }

    charset utf-8;
    listen 80 default deferred; # for Linux
    client_max_body_size 4G;
    server_name _;
    keepalive_timeout 5;
    root /var/www/apps/APP_NAME/current/public;
    try_files $uri/index.html $uri.html $uri @app;

    location ~ ^/(assets)/  {
      root /var/www/apps/APP_NAME/current/public;
      expires max;
      add_header Cache-Control public;
    }

    location @app {
      proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
      proxy_set_header Host $http_host;
      proxy_redirect off;
      proxy_pass http://app_server;
    }

    error_page 500 502 503 504 /500.html;
    location = /500.html {
      root /var/www/apps/APP_NAME/current/public;
    }
  }
}

我在 nginx.conf 中遗漏了什么吗？或在其他文件中？

另外，当我停止 nginx 服务器时，这没有意义，我看到了相同的页面。

我不擅长将应用程序部署到服务器，这是我第一次没有 Heroku，所以我不知道你到底需要知道什么来帮助解决我的问题。因此，如果您需要任何其他信息，请询问，我会将其添加到问题中。

谢谢!

所以，我从 this answer 找到了解决方案.问题出在 Apache Web 服务器上，它在后台运行并阻止 Nginx 在 80 端口上运行。

我已经停止了 Apache 服务器并重新启动了 Nginx，现在一切正常:

sudo apachectl stop
sudo restart nginx
