PM2 restart question (more of a linux question than MM)

[wyovino]

Hi,

I’m trying to restart my mirror nightly with “pm2 restart mm” using a cron job. I’ve tried everything I can think of or find online but nothing works. I’ve created python and bash scripts, used the system crontab and the user crontab. I’ve tried it with and without “sudo” and also running it under the “pi” user. It always works interactively at the command line but not via crontab. Any suggestions?

Also, I saw the warning post about the April 1st upgrade and Pi Zero W. Does that also apply to the Zero 2W?

@wyovino using the user’s crontab from when the job was defined is the most important

so

crontab -e
(no sudo)

and then you would look in the /var/logs folder for the syslog file

and should find a logs entry for the CRON task execution

Mar  1 07:30:01 sams CRON[2992838]: (root) CMD ([ -x /etc/init.d/anacron ] && if [ ! -d /run/systemd/system ]; then /usr/sbin/invoke-rc.d anacron start >/dev/null; fi)
Mar  1 07:30:01 sams CRON[2992839]: (sam) CMD (sshpass -f /home/sam/.idsync sudo rsync ....

it might tell you what is happening to the prior cron jobs. (mine above is rsync just for demonstration)

pm2 might already have cron support

Using the --cron-restart Option
This feature is used to ensure an application, which is intended to run continuously, is refreshed on a regular schedule. 
Command Line:
bash
pm2 start xxxx --cron-restart "0 0 * * *"

pm2 save

no… pi02w is an armv7l processor, pi3 in pi0w physical shape…

Got it!

In the user crontab:

30 2 * * * /usr/local/bin/node /usr/local/bin/pm2 restart mm

Restarts the mirror every day at 2:30 am local time.

As always, thanks for your quick response!
