ICP 2.1.0.3 Enterprise Installation fails to resolve IP names/Hostnames

Question

I am having the same/similar problem with ICP EE.

I have checked everything I can think of:

The master can ping proxy and both workers (by IP address and IP name) my hosts file contains:

127.0.0.0 localhost

10.10.11.247 icp-master

10.10.11.248 icp-proxy

10.10.11.249 icp-worker1

10.10.11.250 icp-worker2

And my ICP Hosts contains:

[master]

10.10.11.247

[worker]

10.10.11.249

10.10.11.250

[proxy]

10.10.11.248

I run the installer and still get the attached error. I have rerun the installer with -vvv and I still cannot see where the error is.

What really confuses me is that:

TASK [check : Checking Hostname is resolvable] - Works

TASK [check : Validating Hostname is resolvable] - Fails!

Whats the difference?

Any help would be much appreciated. Paul B

Please ensure the hostname are correct on all ICP nodes. You can scp your /etc/hosts file from master node to all other ICP nodes, thanks.

Ran 'hostname' on each node, all are correct - subsequently, I took the hyphens out of each hostname, updated all 4 /etc/hosts . Still the same. There seems a lot of discussions around 127.0.0.1 and 127.0.1.1. My reading is that you need the 127.0.0.1 but NOT the 127.0.1.1. – PGB Jun 19 '18 at 07:11
It is tricky that your hosts file includes '127.0.0.0 localhost' record. Normally, it should be: 127.0.0.1 localhost – AsirXing Jun 20 '18 at 04:46
Sorry, typo - it is 127.0.0.1. – PGB Jun 20 '18 at 07:44
Also, I have started from scratch, and it seems to be loading up OK. I think the problem was that I copied the public key to /cluster/ssh.key rather than the private. I will come back with results.... But that could take a while :-) – PGB Jun 20 '18 at 07:45
That fixed the problem leading me to another one. Will open a new Question for that. Thanks for the help folks – PGB Jun 21 '18 at 02:33

Pls change servers' hostname to validate if it matches with your case.
