Ambari Install Wizard won't load

Re: Ambari Install Wizard won't load

New Contributor

Hi Predrag,

I have the three ambari Users ("%", "localhost", and the FQDN (hostname))

use ambari; show tables outputs:

ERROR 1049 (42000): Unknown database 'ambari'

hostname -f outputs:

hostname: Name or service not known

And now when I start ambari-server, this is what I get:

[root@centos7 /]# ambari-server start
Using python  /usr/bin/python2.7
Starting ambari-server

Re: Ambari Install Wizard won't load

Okay, first configure your hostname, for the current session you can just type "hostname YOUR-HOSTNAME", for the full setup refer to this. After that revisit Steps 3 and 4 of "Using Ambari with MySql" document to crate your Ambari database, create tables, and tell ambari-server that you are using MySql. By the way, hostnames must be set on all your nodes, otherwise you'll run into more troubles later.

In the hosts file, there's only two entries

[root@centos7 ~]# vi /etc/hosts

127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4

::1 localhost localhost.localdomain localhost6 localhost6.localdomain6

No entries in: just says created by anaconda

"/etc/sysconfig/network"

For the current session, I typed

# hostname ambarivm

Noting happened
