Centos6 : Chef Node Creation
I thought I’d share the scripts I use to take a fresh Centos6 install and have it configured to work with a Chef server. Maybe its not as easy as when running in a virtualized environment, but it saves plenty of time.
On the new node I run the setup_client.sh script which calls in the end client_gen.sh on the Chef server once everything is installed on the node. I left the version numbers for Ruby and Chef in the script so you know what versions I’ve tested this with.
setup_client.sh
#!/bin/bash CHEF_IP=XXX.XXX.XXX.XXX CHEF=http://$CHEF_IP:4000 CHEF_USER=XXXXX NODE=XXXXXXXX RUBY_VSN=1.3.7 CHEF_VSN=0.9.16 sudo rpm -Uvh http://download.fedora.redhat.com/pub/epel/6/x86_64/epel-release-6-5.noarch.rpm sudo yum update sudo yum install ruby ruby-shadow ruby-ri ruby-rdoc gcc gcc-c++ ruby-devel ruby-static cd /tmp wget http://production.cf.rubygems.org/rubygems/rubygems-$RUBY_VSN.tgz tar zxf rubygems-$RUBY_VSN.tgz cd rubygems-$RUBY_VSN sudo ruby setup.rb --no-format-executable sudo gem install chef -v $CHEF_VSN mkdir ~/.chef cat > ~/.chef/knife.rb <<EOF log_level :info log_location STDOUT node_name '$NODE' client_key '/home/$USER/.chef/$NODE.pem' validation_client_name 'chef-validator' validation_key '/etc/chef/validation.pem' chef_server_url '$CHEF' cache_type 'BasicFile' cache_options( :path => '/home/$USER/.chef/checksums' ) EOF ssh-keygen -t rsa ssh-copy-id -i ~/.ssh/id_rsa.pub $CHEF_IP ssh $CHEF_IP "yes | knife client delete $NODE" ssh $CHEF_IP "yes | /home/$CHEF_USER/client_gen.sh $NODE" scp $CHEF_IP:/tmp/$NODE ~/.chef/$NODE.pem

I chose my favorite and I use Drupal is a web base. I hope that can resolve the problem will not exactly a few problems. Thanks
reality is that if you get a good rails developer they cost is nelbigilge compared to the productivity and quality. It’s been my experience that rails devs care more often about the final product. Just my opinion, no survey’s or stats to back it up.
Cedric,I’m trying to orgianze an ALT.Dev patterns, practices, tools and agile open spaces conference in Boston (next spring) of a kind that was never done before how about combining Alt.Net and Java architects and developers to talk about these topics? All in all we do the same things and there is no reason to have 2 fighting camps.Will you be interested in participating in such an event? Shoot me an e-mail for more details (I don’t have your direct e-mail).
