I''ve been experiencing some odd behavior with puppet and checking the
status of running processes. Let me see if I can explain it:
I have a very simple node.js socket server I''m attempting to puppetize.
It
is managed through an init.d script with start, stop, status, and restart.
The init.d script runs perfectly fine as any other user in the system.
However, when puppet attempts to check status or start the server, it fails
and reports it received ''1'' on exit.
I don''t believe that the script has any hidden requirements of
environment
variables that aren''t getting transferred around -- like I said,
it''s *very* simple.
Additionally, adding debugging echo statements to the script to try and
prove that it''s executing at all don''t appear to fire, either.
It has the
same permissions as plenty of other functioning init scripts. I''m
pretty
much at my wit''s end on this one.
Relevant code:
class service::nodesocketserver {
file { ''/etc/init.d/node'':
ensure => present,
owner => ''root'',
group => ''root'',
mode => ''0755'',
source => ''puppet:///modules/nodejs/node'',
}
service { ''node'':
ensure => running,
enable => true,
hasstatus => true,
hasrestart => true,
require => File[''/etc/init.d/node''],
}
}
/etc/init.d/node is https://github.com/chovy/node-startup with some minor
variations for my specific environment.
Again, everything works great when I run it manually but falls down when I
throw puppet at it. Any advice, more debugging angles I could take?

Re: [Puppet Users] init script status checks and puppet
David, What distro/OS are you running on? Have you tried looking in$APP_DIR/log/app.log ? That init script is not compliant with the Fedora/RedHat spec, so I''m not sure if that would have anything to do with it (or, if you''re on a modern version of a Fedora/RHEL derivative, systemd/upstart take-over...) What are the "minor variations for [your] environment"? They could certainly be the problem, so it would be helpful if you could pastebin/dpaste/gist the actual script you''re running. Here''s a pattern I''ve often used for things like this (note this is from memory, so syntax may need to be adjusted a bit): 1) change the path to the init script (your File resource) to /etc/init.d/node.orig 2) As it *looks* to me like it should work for this script, change the first line of the script to "#!/bin/bash -x" which will run print bash debugging information as commands are run (same as set -x). 3) manually, give /etc/init.d/node this content: #!/bin/bash date >> /var/log/node-wrapper.log echo "Args: $@" >> /var/log/node-wrapper.log # this next line executes /etc/init.d/node with the same args as this script, and logs all output /etc/init.d/node.orig "$@" 2>&1 >> /var/log/node-wrapper.log ret=$? echo "exited $ret" >> /var/log/node-wrapper.log exit $? EOF That will at least give you a log of the date/time, arguments, output/stderr, and exit code. -Jason On 11/22/2013 05:23 PM, David Ashby wrote:> I''ve been experiencing some odd behavior with puppet and checking the > status of running processes.

Any advice, more debugging angles I could take? >Have you checked what the exit code is when you run the script manually? I bet it''s 1. The initscript you link to makes no attempt to return LSB-compliant status codes. See http://refspecs.linuxbase.org/LSB_3.1.1/LSB-Core-generic/LSB-Core-generic/iniscrptact.html. In fact, the initscript also doesn''t use the standard initscript functions to do any of its work (see http://refspecs.linuxbase.org/LSB_3.1.1/LSB-Core-generic/LSB-Core-generic/iniscrptfunc.html), though that''s not likely to present a problem for Puppet.
