Super User is a question and answer site for computer enthusiasts and power users. It's 100% free, no registration required.

I have a simple upstart script:

start on started network-services

respawn
respawn limit 100 5

setuid www-data

exec node /var/testapp/app.js >> /var/log/testapp.log 2>&1

post-start exec echo "Server was (re)started on $(date)" | mail -s "Crashing Server (re)starting" admin@sample-test.com

but because I'm running the node app as 'www-data' I don't have write permissions on testapp.log

What is the best approach to address that?

I would rather not pre-create the log file with 'www-data' as it's owner because I would like as few steps as possible for the setup. I also rather not run the app as 'www-data' with sudo :

exec sudo -u www-data node /var/testapp/app.js >> /var/log/testapp.log 2>&1

because I saw that when I do so the 'root' is also running the process and maybe u'm wrong but i see that as a security issue. If it's not a security issue - please enlighten me.

Thanks!

@igo - i solved it by running the exec like so: exec sudo -u www-data node /var/testapp/app.js >> /var/log/testapp.log 2>&1 –  gilmad Oct 14 '13 at 18:03
