Magento 下订单/结帐超时 - 502 Bad Gateway答案

【问题描述】：

我尝试在 Magento 下订单时遇到 502 错误，我还尝试禁用可下载产品和 RSS 提要。

我收到了订单确认电子邮件，库存已更新，在管理面板中我可以正确查看订单，但我在结帐/onepage/success/ 处没有收到成功消息，而是收到由 a 引起的 502 错误超时。

我得到的唯一错误消息是 os nginx 日志：

2013/12/21 18:49:47 [error] 18449#0: *191 recv() failed (104: Connection reset by peer) while reading response header from upstream, client: 177.103.69.141, server: dev.canalagricola.com.br, request: "GET /checkout/onepage/success/ HTTP/1.1", upstream: "fastcgi://127.0.0.1:9000", host: "dev.canalagricola.com.br", referrer: "http://dev.canalagricola.com.br/checkout/onepage/"

我在一个小型实例（PHP5.5、PHPFPM-5.5、Nginx 1.4.3、Mysql 5.5、Magento 1.8.1）上使用 Amazon Linux（64 位）

【解决方案1】：

apc 需要关闭几个小时，然后您可以将其插入并再次读取日志。还有加速器，有时效果更好。

禁用整页缓存和 apc 并运行 ab -c 1 -n 1 http://www.campsaver.com/

然后用 apc 重启

查看速度、读取日志并启用全页缓存（如果好的话）。

【讨论】：

亲爱的 Arshad，我还没有在这台服务器上安装 APC

【解决方案2】：

Okay,

The above nginx error indicate that issue is related to the fastcgi(php-fpm).

After enabling the "catch_workers_output" on /etc/php5/fpm/pool.d/www.conf Got the relevant error on php5-fpm.log. Now understand that issue is related to AMQP module.

[21-Aug-2013 23:32:57] WARNING: [pool www] child 16091 said into stderr: "php-fpm: pool www: symbol lookup error: /usr/lib/php5/20090626/amqp.so: undefined symbol: amqp_open_socket"

Issue has been fixed afterrecompiled and install amqp module

【讨论】：

亲爱的 Arshad，我启用了 catch_workers_output 并且收到了我在帖子中显示的日志消息。与 amqp 模块没有关系，它没有安装在此服务器上。

【解决方案3】：

我注意到您使用的是 PHP 5.5

根据要求推荐使用的 PHP 版本为 5.2.13 - 5.3.24 http://magento.com/resources/system-requirements

安装推荐的 PHP 版本，看看有没有问题。

【解决方案4】：

重启你的 PHP-FPM：

/etc/init.d/php55-php-fpm restart

如果此问题仍然存在，您可以增加 HTTP 块内的缓冲区和超时：

http {
    ...
    fastcgi_buffers 8 16k;
    fastcgi_buffer_size 32k;
    fastcgi_connect_timeout 300;
    fastcgi_send_timeout 300;
    fastcgi_read_timeout 300;
    ...
}
