问题
I have looked at other answers they dont fit to this case. I am using the full path to the file. Code I copied is simplified.
run.php contains:
shell_exec("php /var/www/html/sync/chourly.php $position $quotientx > /dev/null 2>/dev/null &");
if I use manually php run.php - it works great.
here is the line on crontab -e :
05 * * * * /usr/bin/wget -O /dev/null http://sync.eeeww.com/run.php
again the file run.php starts BUT chourly.php doesn't start. I am using centOS 6 any suggestions please? Addition: I checked the permissions I am using ec2-user to run php run.php and crontab is using the same permission. it is able to run the file but shell_exec is where the issue occurs
回答1:
Is /var/www/html/sync/chourly.php using $SERVER['DOCUMENT_ROOT'] ? Since you're explicitly calling the php interpreter (not mod_php), a `$SERVER['DOCUMENT_ROOT'] call will not work as you expect.
Try manually running the cron from shell to see where it's failing.
cd /
su - your_httpd_usersame -c "/usr/bin/wget -O /dev/null http://sync.bitpine.com/run.php"
