Cron Jobs執行問題

Question

我在Cake PHP中做了一個招標網站。我面臨的主要問題是我需要在服務器上運行CRON JOBS。但我不知道它爲什麼會擾亂我。控制器稱爲'deamons'，它有4種不同的動作，我想每分鐘都在服務器上連續運行，以便我們可以運行該出價站點的每個用戶設置的Autobidder。 的Cron作業我設立是... 捲曲-s -o的/ dev/null的http://www.domain.com/app/webroot/daemons/bidbutler
捲曲-s -o的/ dev/null的http://www.domain.com/app/webroot/daemons/extend 捲曲-s -o的/ dev/null的http://www.domain.com/app/webroot/daemons/autobid
捲曲 - s -o/dev/null http://www.domain.com/app/webroot/daemons/close

和正在處理所有東西的控制器附在下面.... !!! 請建議我一些解決方案，這使

如果專家要測試it..the網址是www.domain.com/app/webroot

這裏是代碼...這我試圖穿過CRONS ...... !!!

CakePHP的方式來運行crons是建立自己的殼完成的任務。 Shell允許您通過命令提示符完全訪問所有控制器。請務必閱讀本文檔開始時：

http://book.cakephp.org/view/108/The-CakePHP-Console

它表明你如何建立自己的殼（應用程序/供應商/殼/），如何組織你彈入任務，以及如何正確地運行shell作爲cron作業。

我這樣做與文檔描述略有不同。我的cron語句是這樣的：

* * * * * (cd /path/to/my/cake/app; sh ../cake/console/cake daily;) 1> /dev/null 2>&1 

從那裏，我只是有一個稱爲殼應用/供應商/殼/ daily.php

<?php 
class DailyShell extends Shell { 

    var $uses = array('User'); 

     function main() { 

       $this->User->processDailyTasks(); 

     } 
} 
?> 

這比在cron使用curl更好，更穩定工作。
