设置ini max_execution_time不起作用

问题描述

在我使用nginx和php-fpm之前，我使用了Apache，因此，当我只希望运行一个cron作业而没有时间执行限制时，我在PHP代码中使用了以下几行:

Before I use nginx and php-fpm, I used Apache, so when I wanted only one of my cron jobs to run without time execution limitation, I used these lines in my PHP code:

set_time_limit(0);
ini_set('max_execution_time', 0);

但是当我从Apache迁移到nginx之后，此代码不起作用.我知道更改nginx.conf来增加最长执行时间的方法.

but after I migrated from Apache to nginx, this code doesn't work. I know ways to change nginx.conf to increase maximum execution time.

但是我想用php代码来处理这个问题.有办法吗?我只想指定一个可以运行PHP代码而没有时间限制的文件.

But I want to handle this with php code. Is there a way?I want to specify only one file that can run PHP code without time limitation.

推荐答案

尝试一下:

使用 Nginx

您可以按照以下步骤增加超时值. PHP的默认值为30s. :

如果要将php脚本的最大执行时间限制从30秒(默认)更改为300秒.

If you want to change max execution time limit for php scripts from 30 seconds (default) to 300 seconds.

vim /etc/php5/fpm/php.ini

设置...

max_execution_time = 300

在Apache中，将PHP作为上述模块运行的应用程序就足够了.但是在我们的情况下，我们需要在另外2个地方进行此更改.

In Apache, applications running PHP as a module above would have suffice. But in our case we need to make this change at 2 more places.

PHP-FPM中的更改

仅当您之前没有对request_terminate_timeout参数进行注释时，才需要使用此命令.默认情况下，它带有注释，并采用php.ini中的max_execution_time值

This is only needed if you have already un-commented request_terminate_timeout parameter before. It is commented by default, and takes value of max_execution_time found in php.ini

编辑...

vim /etc/php5/fpm/pool.d/www.conf

设置...

request_terminate_timeout = 300

Nginx Config中的更改

将example.com的时间限制增加

To increase the time limit for example.com by

vim /etc/nginx/sites-available/example.com

location ~ \.php$ {
    include /etc/nginx/fastcgi_params;
        fastcgi_pass  unix:/var/run/php5-fpm.sock;
    fastcgi_read_timeout 300;
}

如果要增加服务器上所有站点的时限，可以编辑nginx.conf主文件:

If you want to increase time-limit for all-sites on your server, you can edit main nginx.conf file:

vim /etc/nginx/nginx.conf

在http {..}部分中添加以下内容

Add following in http{..} section

http {
    #...
        fastcgi_read_timeout 300;
    #...
}

重新加载PHP-FPM& Nginx

别忘了这样做，这样所做的更改才会生效:

Don’t forget to do this so that changes you have made will come into effect:

service php5-fpm reload
service nginx reload

或尝试

fastcgi_send_timeout 50;
fastcgi_read_timeout 50;

fastcgi有它自己的一组超时，并进行检查以防止其在锁定的进程中停滞.例如，如果您将php的执行时间限制设置为0(无限制)，然后不小心创建了一个无限循环，它们就会加入.或者，如果您运行的是除PHP之外的其他应用程序，则该应用程序没有任何自己的超时保护，并且它失败了.

fastcgi has it's own set of timeouts and checks to prevent it from stalling out on a locked up process. They would kick in if you for instance set php's execuction time limit to 0 (unlimited) then accidentally created an infinite loop. Or if you were running some other application besides PHP which didn't have any of it's own timeout protections and it failed.
