Nginx出现502 Bad Gateway 错误,

查了Nginx的错误日志为:

[html] view plain copy

  1. 2014/08/02 16:14:31 [error] 17029#0: *17941 recv() failed (104: Connection reset by peer) while reading response header from upstream, client: 210.61.12.2, server: blog.lixiphp.com, request: “POST /api/1.0 HTTP/1.1″, upstream: “fastcgi://127.0.0.1:9000″, host: “blog.lixiphp.com”
  2. 2014/08/02 16:24:52 [error] 29615#0: *3 recv() failed (104: Connection reset by peer) while reading response header from upstream, client: 58.220.197.35, server: blog.lixiphp.com, request: “GET /404 HTTP/1.1″, upstream: “fastcgi://127.0.0.1:9000″, host: “blog.lixiphp.com”

不要使用php-fpm的request_terminate_timeout,最好设成request_terminate_timeout=0;

[html] view plain copy

  1. vi /etc/php-fpm.d/www.conf

[html] view plain copy

  1. ; The timeout for serving a single request after which the worker process will
  2. ; be killed. This option should be used when the ‘max_execution_time’ ini option
  3. ; does not stop script execution for some reason. A value of ’0′ means ‘off’.
  4. ; Available units: s(econds)(default), m(inutes), h(ours), or d(ays)
  5. ; Default Value: 0
  6. request_terminate_timeout = 0

因为这个参数会直接杀掉php进程,然后重启php进程,这样前端nginx就会返回104: Connection reset by peer。这个过程是很慢,总体感觉就是网站很卡。

以上就介绍了nginx 502出错集锦,包括了nginx,502方面的内容,希望对PHP教程有兴趣的朋友有所帮助。
