rah*_*286 34 nginx timeout gateway fastcgi php-fpm
调试 6 小时后 - 我放弃了：|
我们在 LAN 中有一个 nginx+php-fpm+mysql，有近 100 个 wordpress（由不同的设计人员/开发人员创建和使用，他们都在测试 wordpres 设置）
我们长期使用 nginx 没有任何问题。
今天，突然间——nginx开始突然返回“504网关超时”......
我检查了虚拟主机的 nginx 错误日志...

当我通过 TCP 模式在端口 9000 上运行 php-fpm 时，我运行了“netstat | grep 9000”并注意到了一些不寻常的东西...... （在此处粘贴部分输出以便于阅读）

有很多“CLOSE_WAIT”和“FIN_WAIT2”对如下突出显示（在上面的输出中）：
tcp 1337 0 localhost:9000 localhost:46680 CLOSE_WAIT -
tcp 0 0 localhost:46680 localhost:9000 FIN_WAIT2 -
请注意上面的端口 46680。
我启用了mysql慢查询错误日志，但是没有用。
截至目前，通过 cronjob（请参阅下面的命令）每分钟重新启动 php5-fpm 保持一切“顺利”运行，但我讨厌拼凑，并想解决这个问题......
1 * * * * service php5-fpm restart > /dev/null
我在谷歌上广泛搜索 - 没有任何帮助。如前所述，这是 LAN 中的测试服务器，CPU 负载永远不会超过 0.10，内存使用率也低于 25%（系统有 2GB RAM 和 ubuntu-server 安装）所以如果你发现它的时间混乱来帮助我，请至少给个提示。
预先感谢您的帮助。

更新：我找到了答案，贴在下面。

我在 nginx 论坛上的帖子中找到了答案 - http://forum.nginx.org/read.php?2,127854
就我而言，答案是设置：
request_terminate_timeout=30s
在 php-fpm 配置中（通常/etc/php5/fpm/php-fpm.conf）
请注意，您也可以使用 30s 以外的值。
我用它来匹配我在主php.ini文件中的值，即：
max_execution_time = 30
谢谢大家。:-)

这是它如何解决我的问题：
在 http { 部分对 /etc/nginx/nginx.conf 进行以下更改
proxy_connect_timeout 600s;
proxy_send_timeout 600s;
proxy_read_timeout 600s;
fastcgi_send_timeout 600s;
fastcgi_read_timeout 600s;
然后重启nginx
/etc/init.d/nginx重启
