Set Up the Uyuni for Retail Environment with Dedicated Network for Terminal

To set up the Uyuni for Retail environment, you will need to have already installed and configured:

  • Uyuni for Retail Server

  • one or more Uyuni for Retail branch server proxies

  • one or more POS images built

1. Assumptions

This guide works only with non-containerized Uyuni for Retail branch proxy 4.3.

In this example we consider architecture with dedicated network for POS terminals where branch server provides all required services including DHCP and DNS.

For dedicated network we assume 192.168.86.0/24 network.

In this example we provide Salt and ftp CNAMEs for Saltboot service discovery.

We assume to have one regular branch server with Salt minion id branch1.mystore.com, which is equal to the branch server fully qualified domain name, and branch id B0001.

As a terminal we assume to have one terminal with hardware manufacturer TerminalOEM and model T1000.

For POS image we assume to have one with name POS_Image_JeOS7.

This example covers two configuration methods. Both of the methods achieve the same result.

2. Create Required System Groups

Manually setting up formulas requires manual creation of the needed system groups, unlike when using the provided tools. To create the system groups, see System Groups.

You will need the following groups:

  • TERMINALS

  • HWType:TerminalOEM-T1000

  • B0001

The first group is generic optional group for collecting all POS terminals. The second group is hardware type group for our POS terminal. The third group is mandatory branch group.

For more information about Saltboot groups, see Set Up the Uyuni for Retail Environment.

3. Assign and Configure Branch Server Formulas

We assign the following formulas to the branch server:

  • Branch Network

  • Dhcpd

  • Bind

  • Pxe

  10. Save the formula

Procedure: Configure Tftpd formula

  1. Select Tftpd formula from branch server formula list

  2. Set the Internal Network Address to 192.168.86.1, this way tftp will be listening on any IPv4

  3. Set the TFTP base directory to /srv/saltboot

  4. Save the formula

Procedure: Configuring Bind with reverse name resolution

  1. Select Bind formula from branch server formula list

  2. In the Config section, select Include Forwarders so DNS server can forward queries to next DNS server
