Question

我对php-fpm和set_time_limit（）有一个奇怪的问题。在我将PHP升级到5.6.30后，之前工作的脚本会因超时而死亡。

<?php
set_time_limit( 300 );
echo "ok";

结果是：

( ! ) Fatal error: Maximum execution time of 30 seconds exceeded in /var/www/hutml/asd.php on line 2
Call Stack
#   Time    Memory  Function    Location
1   0.0002  238976  {main}( )   .../asd.php:0
2   0.0004  239616  set_time_limit ( )  .../asd.php:2

有趣的是，如果我重新启动php-fpm，它可以用于一些请求（3-8），而不是永远停止工作（直到下次重启）。

以下是不起作用的痕迹：

如果您有任何想法/经验/任何事情，请随时与我分享。

感谢。

Answer 1

这是因为系统内存消耗较大。

您必须将php.ini文件的最大执行时间更改为1200毫秒

修改php.ini

后，不要忘记重新启动Apache服务器

Answer 2

我扩展了/etc/nginx/nginx.conf http部分，内容如下：

client_header_timeout 3000;
client_body_timeout 3000;
fastcgi_read_timeout 3000;
client_max_body_size 32m;
fastcgi_buffers 8 128k;
fastcgi_buffer_size 128k;

php set_time_limit（）在php-fpm
