php – 失败(104：由同行重置连接)

Nginx 前端之家
前端之家收集整理的这篇文章主要介绍了php – 失败(104：由同行重置连接)，前端之家小编觉得挺不错的，现在分享给大家，也给大家做个参考。

我们使用的是PHP5-fpm和Nginx.

最佳答案
上面的Nginx错误表明该问题与fastcgi(PHP-fpm)有关.

在/etc/PHP5/fpm/pool.d/www.conf上启用“catch_workers_output”之后
在PHP5-fpm.log上得到了相关的错误.现在了解该问题与AMQP模块有关.

[2013年8月21日23:32:57]警告：[池www]孩子16091对stderr说：“PHP-fpm：pool www：符号查找错误：/usr/lib/PHP5/20090626/amqp.so:undefined符号：amqp_open_socket“

重新编译并安装amqp模块后修复了问题
