脚本宝典收集整理的这篇文章主要介绍了php – nginx错误“recv()失败(104：对等连接重置)从上游读取响应头”，脚本宝典觉得挺不错的，现在分享给大家，也给大家做个参考。
大约有五分之四的浏览器请求成功,但大约五分之一的用户失败了502.
2013/10/05 06:28:17 [error] 3111#0: *54528 recv() Failed (104: Connection reset by PEer) while reading response header From upstream,client: 66.249.66.75,server: www.bec-components.co.uk request: ""GET /?_n=Fridgefreezer/Hotpoint/8591p;_i=x8078 HTTP/1.1",upstream: "fastcgi://127.0.0.1:9000",host: "www.bec-components.co.uk"
有没有办法让PHP给我更多关于它为什么重置连接的信息？
这是Nginx.conf;
user www-data; worker_PRocesses 4; error_LOG /VAR/log/Nginx/error.log; pid /var/run/Nginx.pid; events { worker_connections 1024; } http { include /etc/Nginx/mime.types; access_log /var/log/Nginx/access.log; sendfile on; keepalive_timeout 30; tcp_nodelay on; client_max_body_size 100m; gzip on; gzip_types text/plain application/XMl text/javascript application/x-javascript text/css; gzip_disable "MSIE [1-6]\.(?!.*SV1)"; include /gvol/sITes/*/Nginx.conf; }
这是该网站的.conf;

}

>你的fastcgi / Nginx进程的正常运行时间是多少？
>你监控网络连接？
>你能否确认/否认当天的访客数量变化？
> Nginx无法访问fastcgi-process;要么减慢要么根本不对应.坏网关意味着：Nginx不能fastcgi_pass到那个定义的资源127.0.0.1:9000;在那个非常具体的时刻.
>您的初始错误日志告诉所有：
.
recv() Failed -> Nginx Failed (104: Connection reset by peer) while reading response header from upstream,-> no complete answer,or no answer at all upstream: "fastcgi://127.0.0.1:9000",-> who is he,who Failed???
从我有限的pov我建议：
>重启你的fastcgi_process / server>检查您的访问日志>启用debug-log
