php - 如何在服务器上为 codeigniter 脚本设置 cron 作业

Question

您好，我正在尝试使用 cpanel 为服务器上的脚本设置 cron 作业，但是我从来没有这样做过，如果有人可以指导我，这真的很有帮助。

脚本路径:/home/name/public_html/application/modules/stockupdate/controllers/stockupdate.php

我需要每小时运行一次此脚本，我已阅读教程并尝试使用以下命令:

1) php /home/name/public_html/index.php stockupdate 
2)/home/name/public_html/application/modules/stockupdate/controllers/stockupdate.php

第一个发送以下错误:

<h4>A PHP Error was encountered</h4>

<p>Severity: Notice</p>
<p>Message:  Undefined index: REMOTE_ADDR</p>
<p>Filename: core/Input.php</p>
<p>Line Number: 351</p>

<h4>A PHP Error was encountered</h4>

<p>Severity: Warning</p>
<p>Message:  Cannot modify header information - headers already sent by (output started at /home/name/public_html/system/core/Exceptions.php:185)</p>
<p>Filename: libraries/Session.php</p>
<p>Line Number: 689</p>

<h4>A PHP Error was encountered</h4>

<p>Severity: Warning</p>
<p>Message:  Cannot modify header information - headers already sent by (output started at /home/name/public_html/system/core/Exceptions.php:185)</p>
<p>Filename: helpers/url_helper.php</p>
<p>Line Number: 542</p>

第二个命令向我发送访问被拒绝的错误。如果有人可以指导我创建 cron 作业，我将不胜感激。谢谢

使用 /usr/local/bin/php 而不是 php 让 codeigniter 获取 URI 段。

如果可行，试试这个

/usr/local/bin/php/home/name/public_html/index.php 库存更新索引
