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

My cron job keeps failing in cPanel:
/bin/sh: /opt/cpanel/ea-php73/root/etc: is a directory
I have changed the code, previously it was /usr/local/bin/php
This is the full code:
0 0,12 * * * /opt/cpanel/ea-php73/root/etc /home4/***/****.org/api/fetch.php
Does anyone know the reason? The file fetch.php works fine otherwise. How do I know where the PHP command is?
If you want to run a PHP file in a cron job, you should run with the PHP interpreter. But your error shows that the cron job is running by the Bash interpreter.
This means you have issue with this part /opt/cpanel/ea-php73
You should either revert your interpreter back to /usr/local/bin/php
Or you can use the curl command to run the webpage from an external source.
Eg: 0 0,12 * * * curl ****.org/api/fetch.php
In the PHP script, you're directly executing an incorrect shell command. Probably a missing / prefix in a path.
i want to set a cron job on a server but its not working. I know there are hundreds of links on web that shows how to setup a cron job but i cant seem to make it work. What im doing now is:
1) Running crontab -e.
Then it shows bunch of lines in the command line.
2) I go to the bottom and add */5 * * * * path/to/myfile.php
and then i exit the editor in command line. Please tell me whats wrong here. Do i need to put my file in a specific folder? or do i need to go to the desired folder and then use crontab -e, or something else. Please forgive me, this is my first cronjob, hoping to be better next time.
Here are the pictures of what im doing.
Did you restart the cron service after you updated the file?
Have you tried executing the php script from the command line first to verify that it's executing as expected? It might be that the cron task is executing but the script is failing. If the script is fine, you might want to try using php as a command followed by the path and filename of the php file and then quitting the execution after it's done with -q.
*/5 * * * * php path/to/myfile.php -q
The problem could well be that you are trying to execute a PHP file and your system is unaware of what to do with it.
Is your PHP file executable?
You can make it executable by running
$ chmod +x file.php
and if you add a shebang to it
#!/usr/bin/php
<?php
// ...
the PHP script can be executed by running
$ ./file.php
Alternatively, you need to run the PHP interpreter and pass it the path to the file as an argument.
$ php file.php
For reference, see:
http://php.net/manual/en/features.commandline.usage.php
I have a PHP script that runs perfectly fine on the command line if I simply run it like this php /path/to/script/script.php.
if I now schedule this very command in cron using crontab -e and the add the line:
*/1 * * * * php /path/to/script/script.php 2>&1 >> /var/log/logfile.log
it does get executed every minute as expected and all the output gets put into the log file just like running it on the command line. But the some parts of the script just don't seemt o work. those particular parts are lines that are like:
system('mkdir /mnt/temp', $retVal);
or
exec('mkdir /mnt/temp');
I have tried every possible thing like running it as root, permissions on all scripts and folders that would be affected, using /bin/mkdir instead of mkdir. The return value from the system() is 0 for running it on CLI and 1 for the crontab way.
Any suggestions?
I couldn't solve the CLI vs crontab issue, but the solution that worked for me was to use a bash script inside of cron. And that bash script in turn calls the PHP script. this works like a charm under any of the users that I need to run the script.
So I can't say that it is or isn't a permissions issue.
Thanks for all your comments guys
I need to run a php script to generate snapshots using CutyCapt of some websites using crone job, i get websites' addressess from database and then delete this record after generating screenshots.
i used */5 * * * * /usr/bin/php -f /path/generate.php
it didn't worked for crone job but if i access the same file using browser it works fine, and if run this script using command php from command line it also works fine.
then i just created another file and accessed the url using file_get_contents; added this file to crone job it worked fine for some days but now this approach is also not working. i don't know what happened. i didn't change any of these files.
I also tried wget command to access that url but failed to get required out put.
my crontab is now looks like this
*/5 * * * * wget "http://www.mysite.com/generate.php" -O /dev/null
Strange thing is that crone job executes fine it fetches data from database and deletes record as well but does not update images.
Is there any problem with rights or something similar that prevents it to generate images using crone job but not when accessed using browser.
Please help i am stuck.
I don't know what your script is doing internally, but keep in mind that a user's cron jobs do not inherit the users environment. So, you may be running into a PATH issue if your php script is running any shell commands.
If you are running shell commands from the script, try setting the PATH environment variable from within your php script and see if that helps.
is there any user credintials on this page , such as Basic authentication ?
if so , you have to define the user name and password in wget request like
wget --http-user=user --http-password=password "http://url" ?
and try another solution by running yor script from php command line
so your crontab could look like
*/5 * * * * /usr/bin/php -f /path/to/generate.php
try this solution it will work and it is better than hitting the server to execute background operations on your data
and I hope this helps
I'm trying to run a test script using crontab within Plesk. The php file simply emails me a message
mail('me#somewhere.com','Cron Test','Test');
My path to php is /user/bin/php
I have entered * in every field, to run the script every minute with the following command:
/usr/bin/php -q /usr/httpdocs/crontest.php
However, the script is not being run.
Can anyone help?
I'm probably missing something simple, I've never used cron before.
Any advice appreciated.
Thanks.
I would start by getting it to write to a log file. eg:
* * * * * /usr/bin/php -q /usr/httpdocs/crontest.php >> /a-location/crontest.log 2>&1
This will at least give you any obvious errors like not being able to find php etc.
I found that when using the user based cron in plesk, there are a number of issues:
first I found that you should reference the script from the virtual domain. If your script has an absolute address of /var/www/vhosts/domain.com/httpdocs/email-this.php, you should reference it as httpdocs/email-this.php in the crontab.
Second, the script has to have very particular permissions, but not sure what they "must be." apache:apache is all that ever worked for me. Even with the group write permission set, user still had to be apache... weird.
Third, the easiest way to do the testing was to edit the crontab directly instead of going back into plesk every time I needed to make a change... Edit your crontab like this:
crontab -u [filesystem-username] -e
Fourth, I could never get the crontab to write to a log file outside of httpdocs (I tried statistics/logs/cron_log every way I could think of... lol... no dice). I ended up just adding the MAILTO directive at the top of the crontab file during testing:
eg:
MAILTO=you#domain.com
## * * * * * php -q httpdocs/cron.php
Also see this if you have Plesk 10 or above: http://shaun.net/2011/09/solving-plesk-10-3-1-cron-issues/
I had to do this
/usr/local/psa/bin/server_pref -u -crontab-secure-shell "/bin/sh"
to get this (example) working: wget -O - http://www.yourdomain.com/cron.php
