Finally changed chef-client with an updated recipe to support FreeBSD.
Under the chef-repo/chef-client directory, I added the following files:
./templates/freebsd/rc.d/chef-client.erb ./templates/freebsd/rc.conf.d/chef.erb
And updated:
./recipes/service.rb
The locations corresponds to the directory location under the default #{conf} directory, (which is apparently /etc) The templates are .erb files that corresponds to the configuration files on the server.
chef-client.erb:
[rilindo@chef chef-client]$ cat ./templates/freebsd/rc.d/chef-client.erb
#!/bin/sh
# PROVIDE: chef
# REQUIRE: LOGIN
# KEYWORD: nojail shutdown
. /etc/rc.subr
name="chef"
rcvar=`set_rcvar`
stop_cmd="chef_stop"
command="/usr/local/bin/${name}-client"
command_args="-i -s -d -L /var/log/chef/client.log -c /etc/chef/client.rb -P /var/run/chef.pid"
load_rc_config $name
export rc_pid
chef_stop()
{
pidfile="/var/run/chef.pid"
rc_pid=`cat ${pidfile}`
kill $rc_pid
}
run_rc_command "$1"
chef.erb
[rilindo@chef chef-client]$ cat ./templates/freebsd/rc.conf.d/chef chef_enable="YES"
With ERB, I could have easily have placeholders in the code so that it can be populated with node-specific information automatically. I did not do that in this case, though. That is for another time.
Finally, I updated the service code from:
when "bsd"
log "You specified service style 'bsd'. You will need to set up your rc.local file."
log "Hint: chef-client -i #{node["chef_client"]["client_interval"]} -s #{node["chef_client"]["client_splay"]}"
else
log "Could not determine service init style, manual intervention required to start up the chef-client service."
end
to
when "bsd"
case node['platform']
when "freebsd"
directory "/etc/rc.conf.d" do
owner "root"
group "wheel"
mode "0644"
action :create
end
template "/etc/rc.d/chef-client" do
source "#{dist_dir}/rc.d/chef-client.erb"
owner "root"
group "wheel"
mode 0755
end
template "/etc/rc.conf.d/chef" do
source "#{dist_dir}/rc.conf.d/chef.erb"
mode 0644
notifies :start, "service[chef-client]", :delayed
end
service "chef-client" do
action [:start]
end
else
log "You specified service style 'bsd'. You will need to set up your rc.local file."
log "Hint: chef-client -i #{node["chef_client"]["client_interval"]} -s #{node["chef_client"]["client_splay"]}"
end
else
log "Could not determine service init style, manual intervention required to start up the chef-client service."
end
I am not sure if this is quite “rubyish”, but it works.
At that point, I uploaded the cookbook:
knife cookbook upload chef-client
Added the recipe to the freebsd node:
knife node run_list add freebsddev.monzell.com "recipe[chef-client]"
And ran chef-client. The chef-client program sees the receipe and install the files to the appropriate locations:

I am mostly done now. I just need to start it up with:
/etc/rc.d/chef-client start
I should be able to start automatically. However, getting it to start up automatically upon installation has so far just returns me with:

Essentially, it couldn’t find the PID file in the expected location, which is no surprise, as I had been running chef-client manually without any arguments. Hopefully I can figure out a fix for that soon.
2nd January 2012
Notes: 27
I have been playing around with Chef for the past week and while I liked it, it was a pain it setup. It seems to be work well if you run Debian and Ubuntu. Everything else … not so much.
First sign of trouble is when I attempt to bootstrap the install. The install calls for installing Ruby from the RBEL repo. Which I don’t have too much with trouble - in fact, they have binary RPMs of chef already available, so I used that initially and installed with:
yum install rubygem-chef-server --disablerepo=updates --disablerepo=CentOS-Custom --disablerepo=extras
(Centos-Custom is my own repo, by the way).
That went well - until it turns out that it installed Ruby 1.8 along with it.
So I got that removed. I spent the next few hours of trying (and failing) to install Ruby 1.9 while avoiding have to install 1.8. In the end, I gave up. Instead, what I did is the following:
- Installed the prerequisites for ruby (including my build of Ruby 1.9 and Rubygems).
- Then, I ran “gem install ruby-shadow”, as there was no RPM for it in the CentOS repo.
- Then I installed the EPEL repo (instead of the RBEL repo). That allow to proceed with the install of chef with “gem install chef”. That, in turn, took care of all the requirements and package installation.
The next step is to configure a web proxy, as detail here. I decided to deviate slight and just use Red Hat’s utility with:
genkey chef.monzell.com
And then open the firewall ports.
However, because I had SELinux running, apache is not able to communicate to another application (as they are in different security context. So I had to enable access with:
setsebool -P httpd_can_network_connect on
That got me further, but I still had issues. After tailing the audit log and cat the output to audit2allow, I found that I still need to open a port in SELinux:
#============= httpd_t ==============
allow httpd_t reserved_port_t:tcp_socket name_bind;
I enabled access with:
[root@chef audit]# tail audit.log | audit2allow -M chef444
******************** IMPORTANT ***********************
To make this policy package active, execute:
semodule -i chef444.pp
Installed the module and got the web access working.
There is more, but that’s for another post. :)
(as a side note, is there a tumbler theme that is code friendly - that is, I can paste in code and command line snippets without looking like snot?)
EDIT: Nevermind, looks like I’ll be poking around with CSS again to get it working the way I like.
