如何在服务器上为Codeigniter脚本设置Cron作业

Question

嗨，我正在尝试使用cpanel在服务器上为脚本设置cron作业，但是我从未这样做过，如果有人可以指导我，那将真的有帮助。

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

我已经阅读了教程，并且需要尝试使用以下命令，每个小时都要运行一次此脚本：

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错误消息，拒绝访问。 如果有人可以指导我创建Cron工作，我将不胜感激。 谢谢

stockupdate.php

<?php

    public function __construct()

        $ftp_conn = ftp_connect($ftp_server);
        $ftp_login = ftp_login($ftp_conn, $ftpUser, $ftpPassword ); 

        if(!$ftp_conn)

                                }
                    }
                    fclose($handle);
                    unlink($stock_file);

                else

                    echo "Error reading stock file.\n";
                }
            }
            else 
            {
                echo "There was a problem\n";
            }
        }
    }

Answer 1

我用这个表扬

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

Answer 2

使用/usr/local/bin/php而不是php来获取codeigniter来提取URI段。

所以尝试一下

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

Answer 3

您可以将ob_start()放入配置文件中，以删除最后两个错误。

Answer 4

试试这个工作。

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

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

Answer 5

如此处所述： https : //ellislab.com/codeigniter/user-guide/general/cli.html，您应该获取控制器类名称和方法名称，并使用它们来构建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>

所以对于您的代码：

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

Answer 6

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

将t设置为尝试次数。
