I have the following script in php :
<?php
ini_set('log_errors', true);
ini_set('error_log', __DIR__ . '/cron.html');
error_log("I'm working");
?>
When I execute this script manually by visiting the URL on the browser it works fine and it creates a new file "cron.html" with this content :
[02-Jan-2014 10:25:39 Europe/Berlin] I'm working
But once I try to executed it via Cron it doesn't work. And to see if I have problem with path I told the command on cron to create me a log file.
*/1 * * * * wget -O - -q 'http://www.mywebsite.com/cron.php' > /PATH-TO-FOLDER/crobtab.log
The file crobtab.log is created every single time, but the script is not working at all.
Could this be a problem with the server ? Safe Mode ? Any idea Please ?
I think you should use absolute paths in crontab.
Try this
*/1 * * * * /usr/bin/wget -q -O /PATH-TO-FOLDER/crobtab.log http://www.mywebsite.com/cron.php
or this
*/1 * * * * /usr/bin/curl -o /PATH-TO-FOLDER/crobtab.log http://www.mywebsite.com/cron.php

I need to run a PHP file every 1 hour.
What I'm doing is:
sudo crontab -e
(In the editor) * 01 * * * /usr/bin/php /var/www/devicecheck.php
But somehow, it's not working. The command works on the command line. Before this, I was trying php /var/www/devicecheck.php
Any suggestions?
To execute devicecheck.php every 1 hour try the following:
Method A :: Execute the script using php from the crontab
# crontab -e
00 * * * * /usr/bin/php/var/www/devicecheck.php
Method B: Run the php script using URL from the crontab
If your php script can be invoked using an URL, you can lynx, or curl, or wget to setup your crontab as shown below.
The following script executes the php script (every hour) by calling the URL using the lynx text browser. Lynx text browser by default opens a URL in the interactive mode. However, as shown below, the -dump option in lynx command, dumps the output of the URL to the standard output.
00 * * * * lynx -dump http://www.yourwebsite.com/yourscript.php
The following script executes the php script (every 5 minutes) by calling the URL using CURL. Curl by default displays the output in the standard output. Using the “curl -o” option, you can also dump the output of your script to a temporary file as shown below.
*/5 * * * * /usr/bin/curl -o temp.txt http://www.yourwebsite.com/yourscript.php
The following script executes the php script (every 10 minutes) by calling the URL using WGET. The -q option indicates quite mode. The “-O temp.txt” indicates that the output will be send to the temporary file.
*/10 * * * * /usr/bin/wget -q -O temp.txt http://www.yourwebsite.com/yourscript.php
UPDATE::
# chmod a+x /home/username/yourscript.php
# crontab -e
00 * * * * /home/username/yourscript.php
Script should have execute permission. Give it by
chmod +x /var/www/devicecheck.php
Also check /var/log/syslog for Errors.
I got it to work with wget. You maybe have to install wget first. After it will allow you to run php scripts from a cronjob.
The syntax looks like:
* 01 * * */usr/local/bin/wget "http://localhost/devicecheck.php"
Where /usr/local/bin/wget points to the directory where wget is installed.
If you wish no output just add '-O /dev/null', like this:
* 01 * * */usr/local/bin/wget "http://localhost/devicecheck.php" -O /dev/null
You can also pass parameters in the url:
* 01 * * */usr/local/bin/wget "http://localhost/devicecheck.php?task=somevalue" -O /dev/null
I want to run a .php every 10 min with a cron job on Ubuntu.
This is my crontab:
*/10 * * * * php -f /var/www/html/gapi/src/test2.php >/dev/null 2>&1
And this is in the log file:
CRON[9994]: (root) CMD (php -f /var/www/html/gapi/src/test2.php >/dev/null 2>&1)
In this php is an api call, and I can see the api calls live at the dashboard of the api provider, so I know the php is not running every 10 mins.
I set the file permission to 755, what else can I do to make it work?
Updated Crontab:
*/10 * * * * php -f /var/www/html/gapi/src/test2.php
Try requesting the file through your web server rather than calling the script via the command line PHP interpreter.
*/10 * * * * wget -q -O /dev/null http://localhost/gapi/src/test2.php
(-q to suppress output, -O /dev/null to redirect file output so it doesn't save it)
or using curl instead:
*/10 * * * * curl --silent http://localhost/gapi/src/test2.php
The URL will depend on how your server is set up - you say it works through your browser at the moment so just use the same URL in the cron file.
I worked on magento and I want to run cron job on the server.
If I run domainname/magentofolder/cron.php in the address bar it works.
But when I try to set up cron job on cpanel it will not working.
If executing the php cron file doesn't work you can also try so set up the cron to use the cron.sh file like this:
*/5 * * * * /bin/sh /absolute/path/to/magento/cron.sh
Try this
*/5 * * * * wget -O /dev/null -q http://www.YOURDOMAIN.com/PATH_TO_MAGENTO/cron.php > /dev/null

I want a script file to run once every minute.. I've written this command.
* * * * * php -q /home/<username>/public_html/cron.php
But, this cronjob is not working. whenever, I try to open this file cron.php in browser, it works fine.
I'm using Linux OS. Is there a way to debug it in order to come to know the error?
If you're using Ubuntu as I am, use the full path.
* * * * * /usr/bin/php -q /home/<username>/public_html/cron.php
Have you added an empty line (new line) after your cronjob?
To debug:
Append 2>&1 to the end of your Crontab command. This will redirect the stderr output to the stdout. Then ensure you're logging the crontab's Unix command.
* * * * * php -q /home/<username>/public_html/cron.php; ls -la >>/var/log/cronrun 2>&1
This will capture anything from the Unix command.
A couple of additional hints: Write out the environment variables by issuing the command set with no parameters. And get the shell to echo each command with the set -x command. At the top of your script issue;
set
set -x
For cPanel, you may want to test curl (in case it's installed on your server):
curl --silent --compressed http://www.your-domain.com/cron.php
So it should look similar to: http://grabilla.com/0450d-93d93a32-02ab-457c-ac1c-d2883552a940.html#
You may also want to try removing the -q from your command and see if it helps.
* * * * * php /home/<username>/public_html/cron.php
*/1 * * * * /usr/bin/php -q /home//public_html/cron.php
Add the above line to the crontab file and run it . It will add a cronjob every minute
I have this code bellow to run in command line but is not working. I tried in command line to run without the cron tab and it works. Anyone knows how to fix it ? Thanks in advance.
*/5 * * * * /usr/bin/php /var/www/html/ulchemdb/File_upload/uploads/crontab.php > /dev/null 2>&1
Crontab line is ok:
*/5 * * * * php /var/www/html/ulchemdb/File_upload/uploads/crontab.php
I think the problem with script.
try to run it manualy:
php /var/www/html/ulchemdb/File_upload/uploads/crontab.php
or if You don't have opportunity to get to console do following:
enable error reporting
add line to then end of crontab.php:
echo "\nCOMPLETED SUCCESSFULY\n"
add this crontab line:
*/5 * * * * php /var/www/html/ulchemdb/File_upload/uploads/crontab.php >> /var/www/html/ulchemdb/File_upload/uploads/crontab.log
Also You can share with us Your code, we'll try to help You somehow.
Where is your php is? It can be clarified with "which php" or "whereis php" commands. Use this path as your php executable path.
Try to execute this command manually. Is it works? If no => problem not in crontab.
If yes => remove output redirecting to dev/null for a time (remove part " > /dev/null 2>&1"), use redirecting to log file, for instance:
*/5 * * * * PATH-TO-PHP/php /var/www/html/ulchemdb/File_upload/uploads/crontab.php > /var/log/php.log 2>&1
Investigate a log after some time. Is there something? If no => make sure you script have some output.
try
*/5 * * * * php /var/www/html/ulchemdb/File_upload/uploads/crontab.php > /dev/null 2>&1
