Linux – Hostname configuration for oracle12c on OL7 VM

installationlinuxNetworkoracleoracle-12c

I am trying to install Oracle 12c (for learning/studying purposes)on a VirtualBox VM. i have set up a VM with Oracle Linux 7.4 and when I setup the wireless/networking aspects during installation I decided to change the hostname from:

localhost

to:

OracleLinux7VM

I'm trying to follow along with the Oracle Installation Docuemenation and I'm on the HostsFile configuration section, it states:

"""

For example.

127.0.0.1       localhost localhost.localdomain localhost4 localhost4.localdomain4
192.168.0.215   ol7.localdomain  ol7

Set the correct hostname in the "/etc/hostname" file.

ol7.localdomain

"""

In the terminal on my VM, if I execute:

hostname

it returns

OracleLinux7VM

but if I cat the /etc/hosts file:

127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4

::1 localhost localhost.localdomain localhost6 localhost6

I tried to understanding this through googling and reading the documentation but I'm not sure how exactly I should configure my /etc/hosts file based on my hostname: OracleLinux7VM based in order to successfully install Oracle 12c. Any and all guidance would be greatly appreciated.
