[root@chef-workstation cookbooks]# chef generate cookbook users_group
Generating cookbook users_group
- Ensuring correct cookbook content
- Committing cookbook files to git

Your cookbook is ready. Type `cd users_group` to enter it.

There are several commands you can run to get started locally developing and testing your cookbook.

Why not start by writing an InSpec test? Tests for the default recipe are stored at:

test/integration/default/default_test.rb

If you'd prefer to dive right in, the default recipe can be found at:

recipes/default.rb

[root@chef-workstation cookbooks]# cd users_group/recipes/

[root@chef-workstation recipes]# cat default.rb
#
# Cookbook:: users_group
# Recipe:: default
#
# Copyright:: 2022, The Authors, All Rights Reserved.

search("users","*:*").each do |user_data|
user user_data["id"] do
comment user_data["comment"]
uid user_data["uid"]
gid user_data["gid"]
home user_data["home"]
shell user_data["shell"]
end
end

Non-Default recipe:

[root@chef-workstation recipes]# cat group.rb
search("groups","*:*").each do |group_data|
group group_data["id"] do
gid group_data["gid"]
members group_data["members"]
end
end
[root@chef-workstation recipes]#

[root@chef-workstation recipes]# knife node run_list add Node-1 "recipe[users_group]"
Node-1:
  run_list:
    recipe[users]
    recipe[users_group]
[root@chef-workstation recipes]# 

Note: group non-default recipe is note added with the above command

[root@chef-workstation recipes]# knife cookbook upload users_group
Uploading users_group    [0.1.0]
Uploaded 1 cookbook.
[root@chef-workstation recipes]#

Node1: 



In this above result only user are created but not group, because it is not added to run list with the above command 

To add non-default recipes , please use the below 2 methods:

Method1: 

[root@chef-workstation recipes]# knife node run_list add Node-1 "recipe[users_group]","recipe[users_group::group]"
Node-1:
  run_list:
    recipe[users_group]
    recipe[users_group::group]
[root@chef-workstation recipes]# knife node show Node-1
Node Name:   Node-1
Environment: _default
FQDN:        node1
IP:          192.168.2.133
Run List:    recipe[users_group], recipe[users_group::group]

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.
