Then I open firefox,visit ambari server, http://master:8080 ,but I can't visit,it shows:

Then I view status of ambari-server,it shows:
[root@master ~]# ambari-server status
Using python /usr/bin/python2.6
Ambari-server status
Ambari Server not running. Stale PID File at: /var/run/ambari-server/ambari-server.pid

Why? Where is wrong? I am puzzled with ambari server for several days. How to solve it?

Hi Edward,

I had a problem starting the postgresql on my RHEL6 and fixed it by reinstalling it. Hope this helps:

Reinstall the PostGreSql server:

$ yum remove postgresql-server
$ yum install postgresql-server
$ rm -rf /var/lib/pgsql/data/pg_log
$ service postgresql initdb

Best,
Yixiao

Hi Edward,

It looks like you are having trouble starting postgreSQL. You should try to resolve that issue before starting Ambari.
Also, when the server started and then shut down abnormally, you should check the Ambari server log for the error message. The default Ambari Server Log is under: /var/log/ambari-server/ambari-server.log
I would assume the log will tell you Ambari server failed to connect to the database, please share that log with us.

Best,
Yixiao
