我正在尝试在 AmazonEC2 上运行 php5,其中多个分离的 php-fpm 服务器由 nginx.conf 上的上游块负载平衡。我正在使用两个 t1.micro 实例进行测试,但是当我尝试加载 php 文件时,我的浏览器上出现 502 Bad Gateway 错误。(静态 html 文件工作正常,但无法让 php 文件工作。)
这是我的 nginx 错误日志。
2012/07/11 12:28:21 [错误] 18626#0: *1 recv() 在从上游读取响应标头时失败(104:对等方重置连接),客户端:xxx.xxx.xxx.xxx,服务器: www.example.com,请求:“GET / HTTP/1.1”,上游:“fastcgi://10.xxx.xxx.xxx:9000”,主机:“www.example.com”
有时我会得到这个。
2012/07/11 13:25:51 [错误] 1157#0: *4 上游提前关闭连接,同时从上游读取响应标头,客户端:xxx.xxx.xxx.xxx,服务器:www.example.com,请求: “GET / HTTP/1.1”,上游:“fastcgi://10.xxx.xxx.xxx:9000”,主机:“www.example.com”
我花时间从 ec2 sequrity groups/iptables 打开 9000 端口,并在 nginx 和 php-fpm 上声明本地 IP 地址,所以我认为这不是问题。(我曾经有连接拒绝错误日志)
谁能帮帮我??以下是我的服务器设置和首选项。

[实例2]
