努力使 RoR 应用程序（passenger、nginx）在 EC2 上运行

我在 EC2 Ubuntu 实例上安装了 RoR、ruby、passenger 和 nginx。现在，我正在努力使其工作，并且只能通过如下所示的 ec2 地址进行访问http://ec2-11-222-333-44.ap-southeast-2.compute.amazonaws.com/

我已经完成了所有需要做的事情。但是，我不知道如何设置 nginx。这是我的/etc/nginx/nginx.conf：

user www-data;
worker_processes 4;
pid /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;
  # server_tokens off;

  # server_names_hash_bucket_size 64;
  # server_name_in_redirect off;

  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";

  # gzip_vary on;
  # gzip_proxied any;
  # gzip_comp_level 6;
  # gzip_buffers 16 8k;
  # gzip_http_version 1.1;
  # gzip_types text/plain text/css application/json application/x-javascript text/xml application/xml application/xml+rss text/javascript;

  ##
  # nginx-naxsi config
  ##
  # Uncomment it if you installed nginx-naxsi
  ##

  #include /etc/nginx/naxsi_core.rules;

  ##
  # nginx-passenger config
  ##
  # Uncomment it if you installed nginx-passenger
  ##

  #passenger_root /usr;
  #passenger_ruby /usr/bin/ruby;

  ##
  # Virtual Host Configs
  ##

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


#mail {
# # See sample authentication script at:
# # http://wiki.nginx.org/ImapAuthenticateWithApachePhpScript
# 
# # auth_http localhost/auth.php;
# # pop3_capabilities "TOP" "USER";
# # imap_capabilities "IMAP4rev1" "UIDPLUS";
# 
# server {
#   listen     localhost:110;
#   protocol   pop3;
#   proxy      on;
# }
# 
# server {
#   listen     localhost:143;
#   protocol   imap;
#   proxy      on;
# }
#}


server {
        listen       80;
        server_name  localhost;
        root   /home/ubuntu/my_app/public;
        passenger_enabled on;

        #error_page  404              /404.html;

        # redirect server error pages to the static page /50x.html
        #
        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   /home/ubuntu/my_app/public;
        }
}

我的问题：

  1. 我是否必须在 /my_app/public 目录中有一个 index.html？如果是，那为什么？这是一个 Rails 应用程序，而不是静态应用程序？

  2. 我是否必须指定？root /home/ubuntu/my_app/public;如果是，它与 /public 目录有什么关系？再说一遍，它是一个 Rails 应用程序，而不是静态应用程序？

  3. 我该怎么做才能让它工作呢？

答案1

一些答案：

  1. 不。
  2. 仅在块开头指定 root server {，请查看Nginx 陷阱

  3. 我很确定这是您的评论部分nginx.conf：

    #passenger_root /usr;
#passenger_ruby /usr/bin/ruby;

您没有将它们指向 Passenger + Ruby。（nginx 在收到请求时会运行什么？什么也不运行，就是这样。）

查看此博客在 AWS 上设置 RoR + Passenger用于设置 RoR + Passenger

nginx.conf以下是工作和示例虚拟目录的副本，供您参考。
