Trying to write an upstart script for a newrelic agent

[Mariano González]

Steve

Tried what you suggested, newrelic_rs_dfw_test.conf:

# Upstart script

start on runlevel [2345]
stop on runlevel [016]

respawn

chdir /opt/turner/services/newrelic/newrelic_rs_dfw/

exec bundle exec bin/newrelic_rs

----

/var/log/messages

Feb 18 19:07:50  init: newrelic_rs_dfw_test main process (5149) terminated
with status 1
Feb 18 19:07:50  init: newrelic_rs_dfw_test respawning too fast, stopped
Feb 18 19:07:50  init: newrelic_rs_dfw_test goal changed from start to stop
Feb 18 19:07:50  init: newrelic_rs_dfw_test state changed from running to
stopping

post-stop
Feb 18 19:07:50  init: newrelic_rs_dfw_test state changed from post-stop to
waiting
Feb 18 19:07:50  init: Handling stopped event

----

init (upstart 0.6.5)

----

Run the bundle from the right folder:

[root at server newrelic_rs_dfw]# pwd
/path/newrelic/newrelic_rs_dfw
[root at server newrelic_rs_dfw]# bundle exec ./bin/newrelic_rs
[Tue Feb 18 19:13:23 UTC 2014] WARN: SSL is disabled by default when using
Ruby 1.8.x

And started normally.

----

Tried not being root, and got a gem error:

-sh-4.1$ bundle exec ./bin/newrelic_rs
Could not find rake-10.1.1 in any of the sources
Run `bundle install` to install missing gems.

It does work with sudo.
