我在Cake PHP中做了一个竞标网站。我面临的主要问题是我需要在服务器上运行CRON JOBS。但我不知道为什么它会让我烦恼。我已经开始使用一个名为'deamons'的控制器它有4种不同的动作，我想每分钟在服务器上连续运行，这样我们就可以运行该竞标网站的每个用户设置的Autobidder。
我正在建立的Cron Jobs是......
curl -s -o / dev / null http://www.domain.com/app/webroot/daemons/bidbutler
curl -s -o / dev / null http://www.domain.com/app/webroot/daemons/extend
curl -s -o / dev / null http://www.domain.com/app/webroot/daemons/autobid
curl -s -o / dev / null http://www.domain.com/app/webroot/daemons/close
以及处理所有东西的控制器附在下面.... !!! 请建议我解决这个问题，以便
如果专家想测试它......网址是www.domain.com/app/webroot
这是代码......我试图通过CRONS ... !!!

答案 0 :(得分：2)
CakePHP运行crons的方法是构建自己的shell来完成任务。 Shell允许您通过命令提示符完全访问所有控制器。开始时请务必阅读本文档：
http://book.cakephp.org/view/108/The-CakePHP-Console
它向您展示了如何构建自己的shell（app / vendors / shells /），如何将shell组织成任务，以及如何正确运行shell作为cron作业。
我的方式与文档描述的略有不同。我的cron语句如下：
* * * * * (cd /path/to/my/cake/app; sh ../cake/console/cake daily;) 1> /dev/null 2>&1
从那里我只有一个名为app / vendors / shells / daily.php
的shell<?php
class DailyShell extends Shell {
var $uses = array('User');
function main() {
$this->User->processDailyTasks();
}
}
?>
这比在cron作业中使用curl要好得多，也更稳定。
