通过Crontab Qnap NAS执行PHP脚本

Question

Im trying to run a Script with Cron:

The Cron I used:

ssh: crontab /test.txt

test.txt:

* * * * * /path/to/script/cron/dashboard.php

(I set the Interval to every minute to check if it works)

dashboard.php:

<?php
$con=mysqli_connect("localhost","myuser","mypw","mydb");
$randomnumber = rand(1000,3000);
// Check connection
if (mysqli_connect_errno())
{
echo "Failed to connect to MySQL: " . mysqli_connect_error();
}

mysqli_query($con,"INSERT INTO dashboard (count, date)
VALUES ('$randomnumber', NOW())");


mysqli_close($con);

?>

I inserted the crontab via crontab /test.txt (located in root).

Then executed this line (I followed this tutorial: Qnap Turorial for Crontabs ):

/etc/init.d/crond.sh restart

And I tried to open the Script in a Browser and it worked (I had a new row in my table with a random number and the current date. But If I check my Database every minute nothing new is added through the cron tab..

I run the System through my QNAP NAS...

You could try to edit the default crontab directly:

1. Edit /etc/config/crontab via WinSCP or open it with crontab -e

2. Add your entry * * * * * /path/to/script/cron/dashboard.php

3. Execute the command crontab /etc/config/crontab

4. And finally restart the cron-service with /etc/init.d/crond.sh restart

After those steps, the cron-service should execute the cron-jobs.
