nginx，差分服务器上的php-fpm坏的网关（和安全也）

这是一个多部分的问题。

首先，我有502坏的门户，但我敢肯定，这是因为我下面这些线路之一是错误的。

其次，我很想知道我是如何做'安全明智的'。 我明白，那里的许多指导给了可怕的build议。 我试图聪明地集合所有的知识，但是我很新，所以我可能错过了一些东西。 安全对我来说非常重要，所以如果你喜欢，我会喜欢一个快速而肮脏的“审计”。

对于我的拓扑结构，我正在使用EC2和VPC。 亚马逊Linux AMI。 我有一个弹性负载平衡器，链接到2个nginx服务器。 这些服务器链接到一个单独的php-fpm服务器。

• 在EC2中缩放EC2音量（使其更小）的问题
• 麻烦从webtatic安装php-mysql
• EC2上的自动缩放设置
• MySQL远程访问
• 添加磁盘并调整LVM的大小

1 nginx服务器被禁用，而我debugging这个。

这是我得到的错误。 我觉得这很奇怪，因为我实际上并10.0.0.94在任何地方使用10.0.0.94 （据我所知）。 我正在使用* .210和* .248。

2013/03/27 14:33:10 [error] 2724#0: *1 connect() failed (111: Connection refused) while connecting to upstream, client: 10.0.0.94, server: www.example.com, request: "GET /index.php HTTP/1.1", upstream: "fastcgi://10.0.0.210:9001", host: "xxx.us-east-1.elb.amazonaws.com"

编辑：有一件事我忘了提及。 我认为，因为php-fpm是一个单独的服务器，我读了我必须有相同的文件作为nginx服务器。 我没有rsync或任何设置尚未…我只是上传一个简单的index.php文件到/var/www/html/example.com/index.php作为一个testing。
