How To Setup a Chef 12 on CentOS 7 / RHEL 7
Bootstrapping a New Node with Knife:
Bootstrapping a node is a process of installing chef-client on a target machine so that it can run as a chef-client node and communicate with the chef server.
From the workstation, you can bootstrap the node either by using the node’s root user, or a user with elevated privileges.
knife bootstrap chefclient.itzgeek.local -x root -P pass --sudo
-x: The ssh username
-P: The ssh password
-p: The ssh port
-N: Set your chef-client node name. Leaving this out will usually make hostname being used as the chef-client node name.
–sudo: If the user name on the node will need to use sudo to perform administrative actions, then use this flag. Note: It will prompt you for sudo the sudo password.
Since I didn’t use -N in the command, the hostname will become chef node name.
Doing old-style registration with the validation key at /root/chef-repo/.chef/itzgeek-validator.pem...

Once the bootstrapping is complete, list down the nodes using the following command.
knife node list
Get the client node details.
knife client show chefclient.itzgeek.local

That’s All for now. We will soon meet again with another post on creating chef cookbooks.
