Chef-client runs only locally as root

[Gilles_Devaux]

Hi,

I am trying to execute chef-client remotely but I run into this exception:

I am having the same exception when:

• I invoke sudo chef-client from a non-root user (this is the same use case as trying remotely with ssh ‘sudo chef-client’
• the chef-client deamon runs every 30 minutes -> the deamon runs as root:root: (root 1218 0.0 0.9 92588 19360 ? S Mar10 0:00 /usr/local/bin/ruby /usr/bin/chef-client -d -c /etc/chef/client.rb -i 1800 -s 20 -L /var/log/chef/client.log)

only running chef-client as root locally works.

I have the same $PATH in both cases:

• running as root
• running as sudo (I have included /sbin, /usr/sbin, /usr/local/sbin)

Any help appreciated at this point

Thanks

Hello!

That error looks like one I ran into where 'ruby' wasn't in the $PATH,
though 'ruby1.8' was. Are you on a system like Debian that has
separate ruby1.8 and ruby packages, and 'ruby' isn't installed?

Hi Joshua,

I have more info, this is only happening on the machines where ruby-entreprise is installed.
On these machines ruby is compiled from sources (default install path), gem is compiled from source (default install path). Chef is installed from gem, ruby-entreprise is installed through chef in /opt/ruby-entreprise.

[gilles@selma ~]$ which ruby
/usr/local/bin/ruby
[gilles@selma ~]$ /usr/local/bin/ruby -v
ruby 1.8.7 (2010-01-10 patchlevel 249) [x86_64-linux]

ruby-entreprise is not in the path.

Thanks

--Gilles

ps: I still do not have time to work on merging the changes I made on the cookbooks to be more centos friendly but I will.

More on this:

I added these:
ohai-0.5.0/lib/ohai/plugins/ruby.rb:25 (inside run_ruby)
Ohai::Log.info("path: #{ENV['PATH']}");
status, stdout, stderr = run_command(:command => 'which ruby');

It seems ohai (or chef) runs inside a limited /usr/bin/env. Is there a way to add path at runtime?

I have a workaround using symlinks but it's not ideal.

Thanks

I am having the same exception when:

• I invoke sudo chef-client from a non-root user (this is the same use case as trying remotely with ssh 'sudo chef-client'
• the chef-client deamon runs every 30 minutes -> the deamon runs as root:root: (root 1218 0.0 0.9 92588 19360 ? S Mar10 0:00 /usr/local/bin/ruby /usr/bin/chef-client -d -c /etc/chef/client.rb -i 1800 -s 20 -L /var/log/chef/client.log)

only running chef-client as root locally works.

I have the same $PATH in both cases:

• running as root
• running as sudo (I have included /sbin, /usr/sbin, /usr/local/sbin)

Any help appreciated at this point

Thanks

Hi there!
Have you tried using sudo -E or your distro's method for setting
default PATHs (/etc/profile IIRC)? Also, ssh itself may set the PATH
as described in the environment section of its man page[1].

As you've discovered, we use a shebang line like:
#!/usr/bin/env ruby
This is because the shebang line must specify the absolute path to the
executable, but we can't rely on ruby to be at the same path on all
systems.

1. Linux Manpages Online - man.cx manual pages

HTH,
Dan DeLeo

It seems ohai (or chef) runs inside a limited /usr/bin/env. Is there a way to add path at runtime?

I have a workaround using symlinks but it's not ideal.

Hello!

That error looks like one I ran into where 'ruby' wasn't in the $PATH, though 'ruby1.8' was. Are you on a system like Debian that has separate ruby1.8 and ruby packages, and 'ruby' isn't installed?
