Chef: installation and few basics

Chef is a configuration management tool written in Ruby and Erlang. It uses a pure-Ruby, domain-specific language (DSL) for writing system configuration “recipes”. Chef is used to streamline the task of configuring and maintaining a company’s servers, and can integrate with cloud-based platforms such as Internap, Amazon EC2, Google Cloud Platform, Oracle Cloud, OpenStack, SoftLayer, Microsoft Azure, and Rackspace to automatically provision and configure new machines. Chef contains solutions for both small and large scale systems. Chef is supported on multiple platforms according to a supported platforms matrix for client and server products.^[12] Major platform support for clients includes AIX, RHEL/CentOS, FreeBSD, OS X, Solaris, Microsoft Windows and Ubuntu. Additional client platforms include Arch Linux, Debian and Fedora. Chef Server is supported on RHEL/CentOS, Oracle Linux, Oracle Cloud and Ubuntu.

Before start the Chef tutorial I going to let you know about some Chef specific terminologies :-

ChefDK: Chefhttps://www.linuxmint.com/start/tara/ Development Kits
Recipe : Files where Chef stores instructions, configuration, commands and so on.
CookBook : combination of multiple Recipes called CookBook.
Node: In Chef Node refers to target machine that going to be configured.
Work Station: refers to the machine from which you are going to instruct Chef to do its works.
Chef has Two modes of installation:-
- Chef-solo: for configuration of single machine
- Chef-server :for configuration of several machine ( it could be thousand machines

Prerequisites

- Familiar with Unix/Linux CLI.

Make a file name node.json in root directory:-

{
   "run_list":[
       "recipe[webserver::install_apache]"
   ]
}

Familiar with Vagrant and it’s basic command.
Familiar with

Chef Installation

I am going to install Chef workstation in a Ubuntu vagrant machine. So, I assume that vagrant is already installed in your machine. Firstly, make a directory named chef_tut enter into it and execute vagrant init command in it. Edit the vagrantfile as following:-

comment out line 15:-

# config.vm.box = "base"

add following code between line 69 and line 70

config.vm.define "chef" do |chef|
   chef.vm.hostname = "chef"
   chef.vm.box = "bento/ubuntu-16.04"
   chef.vm.network "private_network", ip: "192.168.33.100"
 end

Save the vagrantfile and start the vagrant host named chef vagrant up chef . Now enter the chef host and start installation of Chef Workstation into it. vagrant ssh chef

Visit this

Chef Workstation: 0.2.53
  chef-run: .chef-workstation/config.toml.
  chef-client: 14.10.9
  delivery-cli: 0.0.52 (9d07501a3b347cc687c902319d23dc32dd5fa621)

At first make a new directory in /vagrant directoryworkstation/0.2.53″>url

to download chef workstation. You could find here Chef workstation for almost every platform. Our OS is Ubuntu-16.04; So scroll down and find the download link for Ubuntu-16.04. We will use wget to download. So, copy the download link and use with wget:-
==============================================================================================================

============================================================================================================

After successful downloaded , now install the chef package using Ubuntu Default Package Manager or dpkg;-

sudo dpkg -i chef-workstation_0.2.53-1_amd64.deb

Make a file name node.json in root directory:-
