In our centos6 server. I would like to execute a php script in cron job as apache user but unfortunately it does not work.
here is the edition of crontab (crontab -uapache -e)
24 17 * * * php /opt/test.php
and here is the source code of “test.php” file which works fine with “apache” user as owner.
<?php exec( 'touch /opt/test/test.txt');?>
I try to replace php with full path of php (/usr/local/php/bin/php) but also it doesn’t work
Thanks in advance,
Please Help me
Cron is a time-based scheduling service in Linux / Unix-like computer operating systems. Cron job are used to schedule commands to be executed periodically.
You can setup commands or scripts, which will repeatedly run at a set time. Cron is one of the most useful tool in Linux or UNIX like operating systems. The cron service (daemon) runs in the background and constantly checks the /etc/crontab file, /etc/cron./* directories. It also checks the /var/spool/cron/ directory.
Configuring Cron Tasks
In the following example, the crontab command shown below will activate the cron tasks automatically every ten minutes:
*/10 * * * * /usr/bin/php /opt/test.php
In the above sample, the */10 * * * * represents when the task should happen. The first figure represents minutes – in this case, on every “ten” minute. The other figures represent, respectively, hour, day, month and day of the week.
* is a wildcard, meaning “every time”.
Start with finding out your PHP binary by typing in command line:
The output should be something like:
php: /usr/bin/php /etc/php.ini /etc/php.d /usr/lib64/php /usr/include/php /usr/share/php /usr/share/man/man1/php.1.gz
Specify correctly the full path in your command.
Type the following command to enter cronjob:
To see what you got in crontab.
To exit from vim editor without saving just click:
And then type
I had the same problem… I had to run it as a user.
00 * * * * root /usr/bin/php /var/virtual/hostname.nz/public_html/cronjob.php
You may need to run the cron job as a user with permissions to execute the PHP script. Try executing the cron job as root, using the command
man runuser). Or create a system crontable and run the PHP script as an authorized user, as @Philip described.
