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 在服务器上为脚本设置 cron 作业，但是我从来没有这样做过，如果有人可以指导我，那将非常有帮助。

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

我每小时都需要运行这个脚本我已经阅读了教程并且我尝试使用以下命令：

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

stockupdate.php

        parent::__construct();

                                $this->stock_update_model->update_stock($product_code, $stock); 
                                }
                                else

                                }
                    }
                    fclose($handle);
                    unlink($stock_file);
                }
                else
                {
                    echo "Error reading stock file.\n";
                }
            }
            else 
            {
                echo "There was a problem\n";
            }
        }
    }

Answer 1

试试这个，它的工作。

php /full-path-to-cron-file/cron.php /test/index

引用[http://www.asim.pk/2009/05/14/creating-and-installing-crontabs-using-codeigniter/]

Answer 2

您可以将 ob_start() 放入您的配置文件中以删除最后两个错误。

Answer 3

如此处所述：https://ellislab.com/codeigniter/user-guide/general/cli.html 您应该获取控制器 class 名称和方法名称，并使用它们构建 CLI 命令，如下所示：

php <path to your CI index.php> <name of the controller class> <name of the function> <optional arguments>

因此对于您的代码：

php /home/name/public_html/index.php stockupdate stock_update

Answer 4

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

如果可行，请尝试此操作

/usr/local/bin/php /home/name/public_html/index.php stockupdate index

Answer 5

wget -t=1 https:// codeginter.com/controller/method

设置尝试次数t。

Answer 6

我用了这个表扬

/usr/bin/curl http://example.com/controller/method
