如何通过CRON运行CodeIgniter文件？ [英] How to run a CodeIgniter file through CRON?

问题描述

我过去尝试过以下方法：

 <？php 
 set_time_limit ; 
 $ _SERVER ['PATH_INFO'] ='cron / controller / index'; 
 $ _SERVER ['REQUEST_URI'] ='cron / controller / index'; 
 require_once（'index.php'）; 
？> 
  

并将其放在codeigniter安装目录中的一个文件中，调用cron.php，然后调用it via：

  php /home/[username]/public_html/my_project/cron.php 
  

如果我在我的浏览器中输入cron.php的URL，它的工作原理，但是每当它通过CRON运行我得到404错误。将以下代码放在CodeIgniter的 show_404（）函数中

  show_404（$ page =''）
 {
 print_r（$ _ SERVER）; 
 echo\\\
\\\
; 
 die（$ page）; 
} 
  

会将以下输出通过电子邮件发送给我：

 数组
（
 [SHELL] => / bin / sh 
 [MAILTO] => me @ gmail.com 
 [USER] => [me] 
 [PATH] => / usr / bin：/ bin 
 [PWD] => / home / [me] 
 [SHLVL] => 1 
 [HOME] => / home / [me] 
 [LOGNAME] => [me] 
 [_] =& usr / bin / php 
 [PHP_SELF] => 
 [REQUEST_TIME] => 1266479641 
 [argv] => Array 
（
 [0] = > /home/[me]/public_html/my_project/cron.php 
）
 
 [argc] => 1 
 [PATH_INFO] => cron / controller / index 
 [REQUEST_URI] => cron / controllers / index 
）
 
 
 home / [me] 
  / pre> 
 
 
这里我用[我]代替我的实际用户名。
 
 
 
 / p> 
 
解决方案
通过CodeIgniter运行cron的最简单的方法是通过应用程序提供cron URL。
 
 
 
然后通过wget调用它
  wget -O  -  -q -t 1 http： /www.example.com/cron/run 
  
在控制器中，您可以使用日志确保
 
 
 
第二种方法是使用lynx 
  / usr / local / bin / lynx -source http://www.example.com/cron/run 
  pre> 
I've tried the following method in the past:
<?php
set_time_limit(0);
$_SERVER['PATH_INFO'] = 'cron/controller/index';
$_SERVER['REQUEST_URI'] = 'cron/controller/index';
require_once('index.php');
?>
and putting this in a file in the codeigniter installation directory, calling it cron.php, and then invoking it via:
php /home/[username]/public_html/my_project/cron.php
If I type the URL to cron.php in my browser it works perfectly, however whenever its run via CRON I get a 404 error. Putting the following code in the show_404() function of CodeIgniter
function show_404($page = '')
{
   print_r($_SERVER);
   echo "\n\n";
   die ($page);
}
results in getting the following output emailed to me:
Array
(
   [SHELL] => /bin/sh
   [MAILTO] => [e-mail]
   [USER] => [me]
   [PATH] => /usr/bin:/bin
   [PWD] => /home/[me]
   [SHLVL] => 1
   [HOME] => /home/[me]
   [LOGNAME] => [me]
   [_] => /usr/bin/php
   [PHP_SELF] =>
   [REQUEST_TIME] => 1266479641
   [argv] => Array
       (
           [0] => /home/[me]/public_html/my_project/cron.php
       )

   [argc] => 1
   [PATH_INFO] => cron/controller/index
   [REQUEST_URI] => cron/controllers/index
)


home/[me]
Here I've [me] in place of my actual username.

Any ideas?
解决方案
The simplest way to run a cron via CodeIgniter is to make a cron URL available via your app.

Then call it via wget
wget -O - -q -t 1 http://www.example.com/cron/run
Inside the controller you can then use a log to ensure the cron is not run too often i.e. if the Google robots trigger it by mistake.

A second method would be to use lynx
/usr/local/bin/lynx -source http://www.example.com/cron/run
