I am getting error while trying to perform Ambari server setup. Can someone provide guidance?

[#1]

[root@sandbox ~]# sudo yum -y install ambari-server

@Manish Anand

Customize user account for ambari-server daemon [y/n] (n)" It appears like Ambari server is trying to create the user. can you keep the default value for " and just press enter and see how that goes?

@apappu

I tried all the options with 'y' , 'n' and no value (enter only). In all these steps, I received the same error.

Hi @Manish,

You cannot run the ambari-server setup command on the Hortonworks Sandbox. It's already been completed for you. Once the Sandbox is running, go to http://127.0.0.1:8888/ to get to the welcome page and to enable your access to the Ambari UI. See blow:

Then click on Quick Links on the botton right to get the Ambari access instructions:

Hi @Ameet,

I am unable to access the Ambari URL even though http://127.0.0.1:8888/ is accessible.

What's the output of ambari-server status command? You should see something like:

[root@sandbox ~]# ambari-server status
Using python  /usr/bin/python
Ambari-server status
Ambari Server running
Found Ambari Server PID: 1356 at: /var/run/ambari-server/ambari-server.pid
[root@sandbox ~]#

If it's stopped, try:

ambari-server start
ambari-agent restart

Then try the Ambari URL again.

Its not running and throwing error for some issue with PostgreSQL.

[root@sandbox ~]# ambari-server status

Hmmm.. interesting. I'm not sure how the postgres DB failed or stopped, but now that we've established this is the Sandbox, I'd suggest just killing this instance and upload a new Sandbox instance and try the steps I've outlined in my first reply.

[#9]

@Manish Anand it could be that in trying to re-run the ambari-server install you inadvertantly corrupted the postgreSQL database that was part of the Sandbox. It makes more sense to blow this away and reimport the Sandbox image rather than try and troubleshoot the problem.

I also recommend that we review one issue per HCC topic. I believe my initial comment answered the original question, but please mark it as so if you agree. Thanks
