Question

当我尝试在Magento下订单时，我得到了502个错误，我还试图禁用可下载产品和RSS源。

我收到订单确认电子邮件，库存更新，在管理面板我可以正确看到订单，但我没有在结帐时获得成功消息/ onepage / success /而是我得到了502错误超时。

我得到的唯一错误消息是os nginx log：

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/"

Answer 1

apc需要被禁用几个小时，然后你可以插入它。再次读取日志。还有eaccelerator，有时甚至更好。

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

然后用apc重新启动

查看速度，读取日志并启用整页缓存（如果正常）。

Answer 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

Answer 3

我注意到你使用的是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版本以查看是否有任何问题。

Answer 4

重新启动PHP-FPM：

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

如果此问题仍然存在，您可以在HTTP阻止内增加缓冲区和超时：

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