Setup FQDN for Ambari install

[#1]

Hi all,

I've 4 VMs on a vps with internet access through a rebond but not visible from the internet. My problem is that i couldn't set the FQDN for each VM. I added this line to /etc/hosts for every VM: "10.10.10.x VMx.local VMx" where x is the number of the VM

Any one have an idea about how to set the FQDN ? and if not is it possible to use IP instead of FQDN ?

i've this config:

Public repond: IP : 151.xx.xx.xx

from the rebond with ssh:

VM | eth0 | | eth1 | VM1 : 192.168.1.10 10.10.10.1 VM2 : 192.168.1.11 10.10.10.2 VM3 : 192.168.1.12 10.10.10.3 VM4 : 192.168.1.13 10.10.10.4

Thanks.

to set the FQDN host name

use the command to set the hostname for temporary hostname test.test.com,

To set hostname permanently add entry in /etc/sysconfig/network for 6

HOSTNAME=test.test.com .

To resolve the all the vm hostname add the hostnamein /etc/hosts file

i.e

10.x.x.x test.test1.com

10.x.x.x new.test1.com

To set hostname permanently in cent os 7

use command

nmtui
