Question Need help with cron tab

[cipcip]

Hi guys,

I need help setting up a crontab on my plesk server. It seems that I cannot get it to work ...

I am using:

*/5 * * * * pgrep -f main.py || nohup python3 cd /var/www/vhosts/criago.com/httpdocs/pie/main.py >> /var/www/vhosts/criago.com/httpdocs/pie/freakin.log

So basically, I want it to run / check every 5 minutes to see if my script is running. If is not running, start it, if it is running skip.

The log files is not getting created and the cron never starts. I am testing with:

ps ax | grep main.py

What I get ?

27781 ? Ss 0:00 /bin/sh -c pgrep -f main.py | pgrep python3 || nohup python3 /var/www/vhosts/criago.com/httpdocs/pie/main.py > test.out
27785 ? S 0:00 python3 /var/www/vhosts/criago.com/httpdocs/pie/main.py
29506 pts/0 S+ 0:00 grep --color=auto main.py

One other thing, I do not understand why I have multiple entries ? How can I delete the extra ones ? Because if I open the file under: /var/spool/cron/crontabs/root , I only have the one that I am using there, not the old ones anymore.

I also tried to use: sudo service cron reload - but it is not starting or the old ones are not being removed.

Thank you,
Cristian.

I have rebooted the server, and now when I do:

ps ax | grep main.py

All I get is:

1761 pts/0 S+ 0:00 grep --color=auto main.py

I do not even see the cron created there....

Try to specify the full path to each command files.

I couldn't get cron to work so I did it using a service.

I have created the file testing.service in /etc/systemd/service/ with:

[Unit]
Description=my criago service crawler
After=multi-user.target

[Service]
Type=idle
User=root
ExecStart=/usr/bin/python3 /var/www/vhosts/criago.com/httpdocs/pie/main.py
Restart=always
TimeoutStartSec=10
RestartSec=10

[Install]
WantedBy=multi-user.target

Then ran the following commands in Putty:

sudo systemctl daemon-reload

sudo systemctl enable testing.service

sudo systemctl start testing

Seems to do the trick. But this is really the correct approach ?

Thank you,
Cristian
