Crontab - Run in directory
(2 answers)
Closed 8 years ago.
I have a php script that sends out a email report with an attached pdf document. I use fopen. If I call the php file manualy it works without any problems and the mails are beeing send as expected.
But:
If the same file should is call by cron job, it does not work at all. The error is:
Warning: fopen(filename.pdf): failed to open stream: No such file or directory in /home/public_html/util.php on line 29
Any ideas how to fix this?
Every cron runs in a minimal environment, which can be a different shell and a different profile than your user account. Also scripts are started not from the containing directory themselves.
In most cases it works, if you just change your directory to the one containing the script like you do when execute the script on the command line shell. Instead of
* * * * * /usr/bin/php /path/to/your/file.php
write this:
* * * * * cd /path/to/your/ && /usr/bin/php ./file.php
If this is not sufficient, you can load your default user shell and your PATH variable with writing
SHELL=/bin/sh
PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin
at the top of your crontab (with the right settings of course, which might be /bin/bash and the output of echo $PATH).
Cron jobs run without any environment, including a current directory. That means that you'll need to use the full path to any files that you want to work with.
If you add a valid email address at the top of your crontab:
MAILTO=your-email#example.com
you'll get any output the cron job does sent to your email. This includes error messages, which can be useful for debugging.

As implied in the title, the Cron Job is supposed to execute a php file (update.php, to be specific). The php file then writes to a csv file stored in the same directory.
I have the time set to * * * * * so that it executes every minute. The command is written as follows:
php -q /home//public_html/wallboard/update.php
I don't believe this is causing any errors, though it also doesn't seem to write to the CSV file. When I visit update.php in a browser, however, it executes and writes to the CSV file immediately. I'm not experienced with Cron Jobs and I'm sure there's an issue, but I don't know what exactly that issue is. Let me know if you have suggestions/questions. Any help is appreciated!
Current Command:
* * * * * usr/bin/php -q /home/<user>/public_html/wallboard/update.php
update.php:
<?php
include('lib/HelpDeskView.php');
include('lib/WallboardDisplay.php');
include('helpdesk.csv');
$helpdesk = new HelpDeskView();
$text="\r\ntest,test,test";
file_put_contents( "helpdesk.csv" , $text, FILE_APPEND);
Since your script resides in your public_html directory you can use wget for your Cron Job
wget -O - -q https://yoursite.com/wallboard/update.php
-O - output is written to the standard output in this case it will go to the email address you specify in CPanel
-q quiet mode
IMHO the best way is to contact support and ask them about command line syntax.
This is how I'm doing it at my linux server using cPanel.
This runs script.php which is stored in public root. Course, replace <username> in command line with your username.
At another server I'm using same command line with /usr/bin/php instead of php at the beginning of line, but I'm aware that not all servers use same command line. Some require php-cli in command line instead of php, some don't "like" -f argument, etc. So try various combinations.
To find more suggestions check out this SO topic too: Run a PHP file in a cron job using CPanel
Important thing: When trying different commands wait at least a minute (this case) to see if it works because Cron doesn't fire your script immediately.
Try to execute the same command in PHP CLI and check if it gives you any error, you might be missing some libraries or references required for CLI execution.
/usr/bin/php -d register_argc_argv=On /home/USERNAME/public_html/DOMAIN/artisan AMIR:HOME
So I have a php file that executes each time it you reload it in the web browser. It uses PHPMailer, to send mail based on criteria in my db. I was attempting to use a cronjob to execute the file which I thought would basically do the same as reloading the page. The php file that I need to run in the cronjob is test.php, and its path is /var/www/html/mailer/test.php.
My cronjob is:
1 * * * * root /var/www/html/mailer/test.php >> /var/www/html/mailer/cron_status.log
and it should be throwing errors into that cron_status.log file, but its empty. I realize that this is firing every minute, but I'm just doing it to test the cronjob, and I really need to set it to 24hrs. With no error output, and no emails landing where they should be, I don't think I've properly setup my cronjob. This is my first time ever trying this. This is on a centos 7 droplet, and I've followed the tutorial from digital ocean with no success.
I need to see the php file to be sure, but you probably need to change it to this:
1 * * * * php /var/www/html/mailer/test.php >> /var/www/html/mailer/cron_status.log
I have several php scripts I am trying to set up (recently moved to a new server) they will run from the command line and through the browser but only one will run through cron the other seems to have a permissions problem, if the file is set to 644 I get this message from cron:
/bin/sh: /home/xyz/public_html/scripts/update-script.php: Permission denied
If I set permissions to 777 I get this message:
/home/xyz/public_html/scripts/update-script.php: line 1: ?php: No such file or directory
/home/xyz/public_html/scripts/update-script.php: line 2: syntax error near unexpected token `"includes/clsDatabase-list.php"'
/home/xyz/public_html/scripts/update-script.php: line 2: ` require_once("includes/clsDatabase-list.php");'
yet the script runs from the command line and via browser AND i have another script that is almost identical to this one (calls for the same include on line 1, is located in exactly same folder) that will run through cron! So I know my paths and cron job that I setup in Cpanel are right. If I copy the working one in the command line, the copied version also fails to run via cron. Thanks!
You need to add a shebang to your file to execute it directly:
#!/usr/bin/env php
<?php
//...
Another option would be calling it like this in your cronjob:
* * * * * php /home/xyz/public_html/scripts/update-script.php
Of course you'd replace the * * * * * with the actual crontab data unless you want it to run every minute.

Cannot get PHP cron script to run
(4 answers)
Closed 8 years ago.
I am running a php script using cron. The name of the file is : PriceChecker.php .
This is my cron script
# m h dom mon dow command
0 07,11,16,20 * * * php /var/www/mainsite/PriceChecker.php
* * * * * /var/www/mainsite/pricecheck.sh
The shell script is:
#!/bin/bash
php PriceChecker.php >logger.log
The first line is the original. The second is for testing
I have tried various variations including: /usr/bin/php /var/www/mainsite/PriceChecker.php
If I log the out in the cron php /var/www/mainsite/PriceChecker.php > logfile.log
The logfile is created, but is empty
Same as here, I think Cannot get PHP cron script to run
You forgot to specify the user name you want your script to be run as.
Specify the full path of the PHP file to be execute
Okay what worked was CDing into the directory of the script

I have several PHP files to be run by cron. I set up the crons using command-
crontab crontab.txt
Inside the crontab.txt file, I have written cron commands like this:-
#(Updating tutor activities) - every minute
* * * * * /usr/bin/wget -O - -q -t 1 http://project/cron/tutor_activities.php
But none of the functionalities are working (database queries, sending reminder mails etc.). Running the URLs manually works.
Then I put my mail address in MAILTO and received the mails. In the mail, I received entire HTML source of the page. What is expected in the mail? Why are my functionalities not working?
Updates
If I change my cron commands to
#(Updating tutor activities) - every minute
* * * * * /usr/bin/wget http://project/cron/tutor_activities.php
Still no success and this comes in my mail -
--15:03:01-- http://project/cron/tutor_activities.php
=> `tutor_activities.php'
Resolving project... IP Address
Connecting to test.project|IP Address|:80... connected.

Length: unspecified [text/html]
index.html.1 has sprung into existence.
Retrying.
And lots of index.html.1 , index.html.2 files are accumulating in the root of my project. I do not want these files to be created. Just want the files to execute.
Same results if I use either of the two commands -
* * * * * /usr/bin/wget http://project/cron/tutor_activities.php
* * * * * wget http://project/cron/tutor_activities.php
running php command with MAILTO set sends me this error /bin/sh: php: command not found.
* * * * * php /path/to/test.php
So, I am not able to use php command.
I have written a simple mailto() inside my test.php. The mail does not come when run through cron (using both wget and php fails) but running the URL manually works.
My problem
To make it clear again, my main problem is that the functionality inside the cron files is not running. Creation of files is a secondary issue.
Any help would be appreciated

if you want to call an url as cronjob, you'll have to use somthing like wget. if it's a php-script on your server it would be easier to use php /...pathtomyscript.../cron/tutor_activities.php
try
which php
The path which is returned should be placed with the command which is passed to run the Cron file.If you are setting up the Cron through Shell,it won't give any problem,but to be assured,try giving absolute path when you are trying to run a php page.
/path/to/php /path/to/cron/script/
Try to give your comand like this,if the problem persists;feel free to discuss.
When you call wget with -O -, it will send the downloaded content to stdout, which cron is sending to you via the email message. In the first case, it's doing exactly what it should.
When you call wget witout the -O parameter, it will try to save the downloaded content as a file of the same name as the web page being downloaded. If it exists, it will add the incrementer to the name, as you saw. In this second case, it's doing exactly what it should.
It's not clear from your question where you want the output to go, but if you want to save the output to the same file each time, use -O myfilename.html.
If your running PHP from cron/command line make sure you put the full path to the php executable
It's entirely possible that PHP's not in the path within the cron environment - it's definitely not going to have the same setup as your regular shell. Try using the absolute path to BOTH the php interpreter AND the php script in the cron command:
* * * * * /path/to/php /path/to/test.php
As for the creation of files, you just have to add a redirect to your wget command:
wget -O - ... http://.... > /dev/null
-O - forces wget to write anything it downloads to standard output, which cron will then happily email to you. By adding the > /dev/null at the end of the command, this output will instead go the Great Bitbucket in the Sky. If you don't want wget's stderr output emailed either, you can also add a 2&>1 after the /dev/null, which further redirects stderr to stdout, which is now going to /dev/null.
I found the problem myself. I did not put the same URL in my crontab file which I was running manually and that was my mistake.
While running manually I was just typing test in the URL, my browsers's list of saved URLs was appearing and I was selecting the URL http://www.test.project.com/cron/tutor_activities.php, but in the crontab file I had put http://test.project.com/cron/tutor_activities.php. I was mistakenly assuming this would run http://www.test.project.com/cron/tutor_activities.php (because we have a rewrite rule present to add www)
But the rewrite rule was redirecting it to http://www.test.project.com/home. That's why the HTML content in the mails.
So, the most important thing to learn here is to make sure we don't miss the minute things and don't assume that we did everything correctly. In my case, better to copy-paste the working URL into the cron file.
An easy and secure (no tmp files) way to do this is to use bash's process substitution:
* * * * * bash -c "/path/to/php <(/usr/bin/wget -O - -q -t 1 http://project/cron/tutor_activities.php)"
Process substitution runs the command within <() and puts the output into a file object that is only visible from the current process. In order to use it from cron, invoke bash directly and pass it as a command string.
And as others have mentioned, use the full path to php which you can find out with which php.
