Pm2: launching pm2 from crontab, script defunct

[naartjie]

I am using crontab's @restart to launch pm2 on my hosted server (webfaction, which is using CloudLinux Server 6.5).

I noticed that afterwards my start_pm2.sh bash script appears as [defunct] in ps -eaf. I can "fix" it if I do something like this:

@reboot start_pm2.sh &> pm2.log &

But then I don't get stderr emailed to me if anything goes wrong (using crontab's MAILTO=).

I was hoping to get some insight on this? Am I going about it the wrong way? I don't have root access, should I be using the startup command with user option?

Thanks!!

This worked for me on CentOS6.4

$ crontab -e

@reboot /root/.nvm/v0.11.9/bin/node /root/.nvm/v0.11.9/bin/pm2 resurrect
*/5 * * * * /root/.nvm/v0.11.9/bin/node /root/.nvm/v0.11.9/bin/pm2 dump

Just replace these values by what is written on the /etc/init.d/pm2-init.sh (node and pm2)

Tell me if it worked for you also

Ah, voila... that works like a charm, thank you ;-)

I was doing a pm2 start processes.json as part of my start_pm2.sh script.

The command above doesn't worked in my app. When run pm2 commands (like start, resurrect) from crontab, my app doesn't start properly. But when i manually run the command it starts well..

Here is the error i got:

On top of the it says: The app restarted 15 times so it is stopped (errored)

Was there ever a resolution to this @juliousglori ?
