There is no way to get ambari UI after installation

[#1]

I installed ambari and setup it with help this man: https://docs.hortonworks.com/HDPDocuments/Ambari-2.6.1.0/bk_ambari-installation/content/log_in_to_ap...

I user virtualbox on which installed centos7.

I installed ambari-server, after I started it. It started with message "Server started listening on 8080". But I can't get ambariUI at all. My inet address in ifconfig -a is "inet 10.0.2.15". So I try to ping 10.0.2.15:8080 and it messages that no such service or server. After I tried to connect via browser, it's the same. I can't get AmbariUI and I don't know how to fix it. It seems to be easy but something went wrong. After ambari installation and starting it I checked log file and everything is fine. So what's the problem can't got it.

Thank you.

Try to see if process if running or not

ps -ef | grep ambari-server

see whether port is lessoning

lsof -nalp | grep 8080

Then if everything is working as expected, the try with full qualified domain name like FQDN:8080

Hope this helps you.

Thank you for your answer. It doesn't work with FQDN.

[root@localhost /]# hostname -f

localhost

[root@localhost /]# ping localhost:8080

ping: localhost:8080: Name or service not known

Hi @David Manukian

This seems to be a virtualbox network configuration issue. Check your port forwarding and add a rule for 8080.

[#6]

I added it

Thank you for your answer. It doesn't help. As well as I can't even to ping it.

@David Manukian

Are you accessing the Ambari from your Virtual box host? If so make sure the VirtualBox IP entry is in your local host's file in C:\Windows\System32\drivers\etc assuming you are using windows.

In the below example my VirtualBox network setting is set to Bridged adapter so it picks my LAN network a class C

192.168.0.227  sandbox.hortonworks.com sandbox

So I can access my Ambari from my laptop using http://sandbox:8080

I think 10.0.2.15:8080 is only accessible if you are running firefox from the virtual box can you verify using curl

curl -u username:password -G http://ambari_server_ip:8080/api/v1/check

The desired output should be running that will confirm ambari is indeed accepting connections

I can get connect to virtual host from local. My virtualhost ip address is 192.168.0.75 and when I make ping from local host it works but when I try to add port 8080 for checking ambari it doesn't work and the browser the same situation. I tried to rich via curl in virtualbox as you suggested and it works.

My networks is bridge-netowork and host-only as well. Neither bridge nor host-only doesn't allow me to make request from local machine
