Crontab does not execute script

I’m trying to run a script by crontab of centos, I’m doing so:

crontab -e

then put:

*/1 * * * * root /home/websites/public_html/admin/functions/open.sh

Obs: Before doing this, add permissions to the file

chmod +x open.sh

I’m right, where I’m wrong?

The script is programmed to run the following:

teste=`ps aux | grep web_socket | grep -v grep`;

# Testando se o IM gaim está rodando
if [ "$teste" ];
then
    echo "Socket ON"
else
    echo "Socket OFF"
    killall php -q web_socket2.php
    php -q web_socket2.php &
fi

Briefly is a verifier to see if the service socket is active, if it is not should close the traces of the service and activate it

linux shell centos crontab

  • Check the cron log with the " Tail -fn 50 /var/log/cron "command. And check what you’re saying there! Another thing for that " root " before the executable path ?

  • within the path there is no cron log, this is normal?

  • No centos distro! Usually the log is in var/log cron file! Strange not to have, it may be possible that the person who set up the cron service has deleted the log.

  • Try to run the script directly on the command line.Wheel?

  • Come on, I wasn’t showing the log pq had dropped from ssh and I hadn’t noticed kkkk, it was wrong. Okay, first: I’m using root in front pq I saw on the web that was to use root, but I don’t know if it’s necessary. Second: the log that appeared to me is I’ll put in the post

  • cron is running the routine as you can see in the log. What should this script do that it doesn’t? Have you tried running it directly inside the bash ?

  • 1

    You can play the script error inside a file like this: */1 * * * root /home/websites/public_html/admin/functions/open.sh > /home/websites/public_html/error.txt

  • I get it, I’ll put the txt and as soon as generate show for you, on what this script should do I’ll post in the post to you check.

  • When I execute the command in hand it rotates normally

  • 1

    also run in bash php -q web_socket2.php, it should be something inside it. If possible post its contents for me to see!

  • Boy, you’re a genius kkkk. Exaggerations the part you made me reason a little bit more here, as you can see above, I was calling the information in a generic way, and now I called the literal way and it worked, anyway, thanks man, it helped even here. I’ll post my solution.

  • Don’t overdo it! I was going to post a note again, happy to have you solved! = P

  • Vlw man, I just need to set it right now as solved, please do so, I answered below, copy and paste in another answer so I can draw as solved and score you please. Vlw.

I concluded the question as follows::

teste=`ps aux | grep web_socket | grep -v grep`;

if [ "$teste" ];
then
    echo "Socket ON"
else
    echo "Socket OFF"
    killall /usr/local/bin/php /home/websites/public_html/admin/functions/web_socket2.php
    sleep 3; /usr/local/bin/php -q /home/websites/public_html/admin/functions/web_socket2.php &
fi

I mean, I was using a generic path, I just needed to add the literal path.

  • punctuated as correct! I do not need these points is quiet king, I was already happy!

  • Opa, tranquil to using more the community now and ta making a lot of difference!! vlw!
