在ec2上使用多php fpm服务器实例运行nginx时出现连接错误
我试图在AmazonEC2上运行php5,使用nginx.conf上的上游块平衡多个分离的php fpm服务器负载。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,浏览器上出现了502错误网关。(静态html文件工作正常,但无法使php文件正常工作。) 这是我的nginx错误日志 2012/07/11 12:28:21[错误]18626#0:*1 recv()失败(104:连接失败 从上游读取响应头时,由对等方重置),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” 有时我也会这样 2012/07/11 13:25:51[错误]1157#0:*4上游提前关闭 从上游读取响应头时的连接, 客户端:xxx.xxx.xxx.xxx,服务器:www.example.com,请求:“获取”/ HTTP/1.1“,上游:fastcgi://10.xxx.xxx.xxx:9000“,主持人: “www.example.com” 我花时间从ec2 Sequerity Group/iptables打开9000个端口,并在nginx和php fpm上声明本地ip地址,所以我认为这不是问题。(我以前有连接被拒绝的错误日志) 有人能帮我吗?? 下面是我的服务器设置和首选项 [实例1]在ec2上使用多php fpm服务器实例运行nginx时出现连接错误,nginx,amazon-ec2,centos,php,Nginx,Amazon Ec2,Centos,Php,我试图在AmazonEC2上运行php5,使用nginx.conf上的上游块平衡多个分离的php fpm服务器负载。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,浏览器上出现了502错误网关。(静态html文件工作正常,但无法使php文件正常工作。) 这是我的nginx错误日志 2012/07/11 12:28:21[错误]18626#0:*1 recv()失败(104:连接失败 从上游读取响应头时,由对等方重置),客户端: xxx.xxx.xxx.xxx,服务器:w

我终于明白了 我仍然不知道为什么,但通过在我的每个实例上分配弹性ip,并使用私有ip而不是私有DNS地址,解决了我的问题 所以我的conf文件现在看起来像这样以防万一 [nginx.conf]

谢谢 日志里有什么?您的php脚本可能是针对php fpm的segfaulting.logs?我没有收到日志级别为“notice”的php fpm的错误日志。我可以从CLI运行php文件,但是否仍有可能获得SEGFULTS?php服务器上的文档根目录是否与Nginx服务器上的文档根目录不同?我仔细检查了一遍,但似乎我有正确的权限。。。无论如何谢谢你!
