[英]Trouble running a PHP script with CRON
I created a php file I want to run all the time. 我创建了一个我想一直运行的php文件。 I then created a basic wrapper I want CRON to run to insure the script is still running - and restart it if needed.
然后,我创建了一个我希望CRON运行的基本包装器,以确保脚本仍在运行-并在需要时重新启动它。
My crontab -e
entry is like this: 我的
crontab -e
条目是这样的:
20 * * * * /var/www/bot/cron.php
The contents of cron.php look like this. cron.php的内容如下所示。
#!/usr/bin/php
<?php
@exec ('ps aux | grep loop', $output, $ret_var);
$running = false;
foreach ($output as $line)
{
if (strpos($line, 'bot.php') !== false)
{
$running = true;
break;
}
}
if (! $running)
{
@exec('/usr/bin/nohup php ' . __DIR__ . '/bot.php >/var/log/bot_out 2>&1 &');
}
die();
However, I'm having trouble getting this working. 但是,我无法正常工作。 Is there something I'm missing?
有什么我想念的吗?
I'm not getting anything on any error log, and /var/log/bot_out
does show some runtime errors so I know PHP must be called. 我没有在任何错误日志中得到任何信息,并且
/var/log/bot_out
确实显示了一些运行时错误,因此我知道必须调用PHP。
PHP Warning: Module 'apc' already loaded in Unknown on line 0
PHP Warning: Module 'suhosin' already loaded in Unknown on line 0
20 * * * * /var/www/bot/cron.sh
then contents of cron.sh 然后是cron.sh的内容
#!/bin/bash
KP=$(pgrep -P 1 -f bot.php)
if [ "X$KP" = "X" ]
then
/usr/bin/nohup php PATH_TO_YOUR_SCRIPT/bot.php
fi
