Confirm Hosts Failed for a local Linux PC

New Contributor

Hello,

I would like to make a very simple installation on a local Linux PC.

So at the Install Options Target Hosts I choosed : localhost.local

I read that it should be a Fully Qualified Domain Name (FQDN) and that it should be localhost.local and not simply localhost

And then I choosed :

Perform manual registration on hosts and do not use SSH

I did perform the manual registration according to

https://docs.hortonworks.com/HDPDocuments/Ambari-2.6.2.2/bk_ambari-administration/content/install_th...

where I put int the ambari-agent.ini file :

[server]
hostname=localhost.local
url_port=8440
secured_url_port=8441

then at the next install step the Confirming Hosts step is failing.

I had a look at the /var/log/ambari-agent.log file which says :

INFO 2018-07-02 14:54:15,196 PingPortListener.py:50 - Ping port listener started on port: 8670
WARNING 2018-07-02 14:54:20,199 main.py:441 - Unable to determine the IP address of the Ambari server 'localhost.local'
INFO 2018-07-02 14:54:20,200 NetUtil.py:70 - Connecting to https://localhost.local:8440/ca
WARNING 2018-07-02 14:54:25,205 NetUtil.py:101 - Failed to connect to https://localhost.local:8440/ca due to [Errno -2] Nom ou service inconnu  
WARNING 2018-07-02 14:54:25,205 NetUtil.py:124 - Server at https://localhost.local:8440 is not reachable, sleeping for 10 seconds...

Please what do you suggest to make it work ??? I only need a very simple installation (no need for ssh and other servers for the moment)

Thanks in advance !

Can you share your hosts file?

Sure here it is :

127.0.0.1    localhost
127.0.1.1    philippe-All-Series-Invalid-entry-length-16-Fixed-up-to-11

# The following lines are desirable for IPv6 capable hosts
::1     ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters

@Philippe Kevorkian

You can simply use "localhost" in config files.

However, Do update the first line with below to resolve "localhost.local"

127.0.0.1    localhost localhost.local

Please leave all the line linked ti IPv6 and update the line as stated by Sandeep, but I am wondering what is the output of the below commands

$ hostname 

or

vi /etc/hostname

Run the below command to get your ip, please append sudo where needed

$ ifconfig

The above steops should give you the output to add in your /etc/hosts the format is IP/hostname/Alias eg

192.145.90.10     myhdp.ubuntu.com    myhdp

With the above entry you can the Alias during the registration of the hosts in Ambari
