How to set up Cron to trigger a Rake?

  • Posted December 22, 2013

Hello - I have a rake task that I’d like to schedule a cron to run. My Rails 4 droplet is running Ubuntu 12.10 (Nginx + Unicorn).

Here’s what I have in crontab: SHELL=/bin/bash PATH=/sbin:/bin/usr/bin HOME=/ MAILTO=“xxx@gmail.com”

          • /bin/bash -l -c ‘source ~/.bash_profile && cd /home/rails && RAILS_ENV=production bin/rake populate:fetch_nr_songs’

I get this error /etc/profile.d/rvm.sh: line 9: ps: command not found /etc/profile.d/rvm.sh: line 10: ps: command not found /usr/local/rvm/scripts/rvm: line 96: dirname: command not found ERROR: Missing proper ‘which’ command. Make sure it is installed before using RVM!

Any fix would be much appreciated thanks

Thanks Kamal!!! Removing those variables and changing my RAILS_ENV caused it work!

Did it have all those variables by default? Try resetting it to how it was before you edited it and using <code>crontab -e</code> to edit the cron instead.

Thanks Kamal for all the help. Unfortunately now the cron doesn’t run at all, I don’t even get emails with error messages :( <br> <br>The crontab I’ve been editing is located in etc/default

That’s because you have HOME set to <code>/</code>. Delete that line too.

Now I get this error message: <br>/bin/bash: //.bash_profile: No such file or directory <br>

<blockquote>PATH=/sbin:/bin/usr/bin </blockquote> <br>Try deleting that line, does that fix it?
