服务器前端浏览器报502的时候, 查询代理服务器Nginx的日志中有:upstream sent too big header while reading response header fromupstream, client很明显这个是后端服务器返回的header过大导致. 根据之前的文章:Nginx Buffer 简记 - Nginx Proxy 相关Buffer性质与配置关系 - proxy_buffer_size - proxy_buffers - prox...
面对服务器前端浏览器出现502错误的情况，检查Nginx日志，发现问题是由于上游服务器返回的header过大导致。根据已有的知识，对于这类问题的关键配置在于proxy_buffer_size，用于缓冲从代理服务器接收到的第一部分响应，即header部分。Nginx的proxy_buffer_size默认等于一个内存页面的大小，通常为4K或8K，具体取...
'error.log'报错信息: "recv() failed (104: Connection reset by peer)" while reading 'response header from upstream' 'access.log'表现:'502 Bad Gateway' 报错原因:'upstream后端'服务已经断开了连接,但是'未通知'到nginx,nginx还在该连接上'等着收发'数据,最终导致了该'报错'. 表现为:'被调用方[后端...
排查过程 1、在服务器上开启tcpdump抓包 tcpdump -nps0 -iany -w /tmp/20180617.pcap net [ip] and net [ip],如果不知道tcpdump怎么使用的同学可以百度一下。 2、在nginx的error.log中观察到到有两条" upstream prematurely closed connection while reading response header from upstream"错误日志,分别是2018...
之前线上的服务,最近访问量大了之后,nginx的error日志中大量出现upstream timed out (110: Connection timed out) while reading response header from upstream这种错误。 虽然目前为止,问题的根本还是没有太清楚,但是先记一下自己的排查方法,明天可以继续排查: ...

upstream sent too big header while reading response header from upstream 你去搜这个错误,网上的解释都差不多,无外乎是cookie携带的header太多了,让你设置: fastcgi_buffer_size 128k; fastcgi_buffers 8 128k; 逐步尝试。其中fastcgi_buffers 8 128k 这句,fastcgi_buffers 32 32k 这样更好,内存是整块分配和释...
