Chef Workstation ships with a toolbar application, the Chef Workstation App.
To run this application some additional dependencies must be installed.
Using your platform's package manager to install the 'electron' package is
the easiest way to meet the dependency requirements.

You can then launch the App by running 'chef-workstation-app'.
The App will then be available in the system tray.

Thank you for installing Chef Workstation!
You can find some tips on getting started at https://docs.chef.io/workstation/getting_started/

[root@localhost opt]#
[root@localhost opt]#
[root@localhost opt]# rpm -qa chef*
chef-workstation-22.4.861-1.el7.x86_64

Verify Installation :

[root@localhost opt]# rpm -qa chef*
chef-workstation-22.4.861-1.el7.x86_64
[root@localhost opt]#

2).  Chef Server Configuration

chef Server software link: https://api.chef.io/login











we will get one email notification to activate chef server account. 





Enter the password which ever you like and remember the password for next logins . 

The first thing you’ll do is go to the administration tab and download the starter kit.


Chef starter will be downloaded in zip format,  unzip it and copy to other folder where you want keep the chef files.
 
In my case I coped to G:\DEVOPS\Chef  in windows.




Open command CW Power shell, Icon is created while check-workstation installation on our desktop. 

Linux :  copy this chef-starter folder to Linux server using WinScp.

3).  Worker Nodes.

Windows:

Go to Chef-repo location in power shell with the below command 

        cd G:\DEVOPS\Chef\chef-starter\chef-repo

Able to see all the files in that location: 

Attaching a Node1 to chef server with the below command

knife bootstrap <Node IP> -U root -P <Password> -N Node-1

  eg: knife bootstrap 192.168.2.128 -U root -P root123 -N Node-1

If you get this error first time use this command for the first command :

PS G:\DEVOPS\chef-starter\chef-repo> knife bootstrap 192.168.2.133 -U root -P root123 -N Node-1
ERROR: LicenseAcceptance::LicenseNotAcceptedError: Missing licenses for the following:

       * inspec

PS G:\DEVOPS\chef-starter\chef-repo> knife bootstrap 192.168.2.133 -U root -P root123 -N Node-1 --chef-license accept

In check server it will see as below once it is added. 


Copy starter KIT: /opt/chef/chef-starter

[root@localhost chef-repo]# cd /opt/chef/chef-starter/chef-repo
[root@localhost chef-repo]# ls -ltr

To change the data directory location for PostgreSQL after installation

 To change the data directory location for PostgreSQL after installation, you'll need to move the existing data to the new location and update PostgreSQL's configuration to use the new directory. Here’s a step-by-step guide to achieve that: 1. Stop PostgreSQL service : First, stop the PostgreSQL service to ensure no data is being accessed or written during the move. sudo systemctl stop postgresql-15 2. Create the new data directory : Create the new directory where you want to move your PostgreSQL data, and set the appropriate permissions for the postgres user. sudo mkdir -p /new/postgres/pg_data sudo chown postgres:postgres /new/postgres/pg_data sudo chmod 700 /new/postgres/pg_data 3. Move the existing data : Move your existing data from the old directory to the new directory.
