Installing Chef solo, knife solo and confirming chef-solo runs with knife solo

Very begging of installing and setting up chef to use knife solo mainly for me.

Updating the latest packages and git

$ sudo yum -y update git

Installing Chef

$ curl -L https://www.opscode.com/chef/install.sh | sudo bash

Installing knife-solo

$ sudo /opt/chef/embedded/bin/gem install knife-solo --no-ri --no-rdoc
$ knife -v
Chef: 11.14.2

Confirming the path in which knife is installed

$ ll `which knife`
lrwxrwxrwx 1 root root 19 Aug  5 04:32 /usr/bin/knife -> /opt/chef/bin/knife

Configuring knife

$ knife configure \
-y \
--defaults \
-r /home/ec2-user/chef-repo
WARNING: No knife configuration file found

Uninstalling Chef (if needed)

$ yum -y remove `rpm -q chef`

Creating cookbook

$ knife cookbook create hello -o site-cookbooks

Creating recipes

site-cookbooks/recipe/hello/default.rb

log "Hello, Chef!"

Creating node object file to execute recipe
This is just to confirm that knife solo runs at localhost.

node/localhost.json

{
  "run_list" : [
     "recipe[hello]"
  ]
}

SSL validation of HTTPS requests is disabled. HTTPS connections are still
encrypted, but chef is not able to detect forged replies or man in the middle
attacks.

To fix this issue add an entry like this to your configuration file:

```
  # Verify all HTTPS connections (recommended)
  ssl_verify_mode :verify_peer

  # OR, Verify only connections to chef-server
  verify_api_cert true
```

To check your SSL configuration, or troubleshoot errors, you can use the
`knife ssl check` command like so:

```
  knife ssl check -c /home/ec2-user/chef-solo/solo.rb
```

If the SSL warning message appears, it is possible to disable by adding an entry on solo.rb. The detail is show at official HP, knife ssl check.

Next is to install chef and cookbook on a remote host with knife solo and install a package.
