This is an optional step, which details how to specify the Secure Node Hostnamenode hostname

Description

Command

1

Update the /etc/hosts file

- Replace the default hostname with your desired hostname
  - The default hostname typically follows "127.0.1.1", DO NOT REPLACE "localhost"
  - See example in bold
  - You may need to disable "manage_etc_hosts" like in the example
- Save and exit with CTRL+x, then type y and hit enter.

NOTE: In the example I use "zsec01node01" as my hostname. I'm using the same hostname as my example FQDN:

zsec01node01.zentest.win

# Your system has configured 'manage_etc_hosts' as True.
# As a result, if you wish for changes to this file to persist
# then you will need to either
# a.) make changes to the master file in /etc/cloud/templates/hosts.tmpl
# b.) change or remove the value of 'manage_etc_hosts' in
#......./etc/cloud/cloud.cfg or cloud-config from user-data

127.0.1.1 zsec01 node01
127.0.0.1 localhost
