Unable to determine server PID.

[#1]

I am trying to install Ambari 2.5.2.0 following the steps indicated in

https://docs.hortonworks.com/HDPDocuments/Ambari-2.5.2.0/bk_ambari-installation/content/ch_Getting_R...

I use Ubuntu 14 My Internet access is through a proxy and I tried the following two configurations: embedded PostgreSQL, and a standalone PostgreSQL. In both cases, I have the same error when I start Ambari server. The error message displayed on the screen is the following:

Server PID at: /var/run/ambari-server/ambari-server.pid Server out at: /var/log/ambari-server/ambari-server.out Server log at: /var/log/ambari-server/ambari-server.log Waiting for server start.........Unable to determine server PID. Retrying... ......Unable to determine server PID. Retrying... ......Unable to determine server PID. Retrying...

ERROR: Exiting with exit code -1. REASON: Ambari Server java process died with exitcode 1. Check /var/log/ambari-server/ambari-server.out for more information.

Please, do you have any idea of the origin of the problem?

The content of ambari-server.out file is the following:

@unes abd

There seems to be two errors, Both might be related.

Error-1). Ambari Server process is not able to determine its PID.

Unable to determine server PID. Retrying... ......Unable to determine server PID

>>>> For the PID issue, Can you please let us know if you are running Ambari Server as a "root" user or a Non Rot User?
If you are running the ambari-server as Non Root user then please refer to the doc to make sure the all the required steps are followed:
https://docs.hortonworks.com/HDPDocuments/Ambari-2.5.2.0/bk_ambari-security/content/how_to_configure...

Also please check the directory if it's permissions are correct and writable?

# ls -ld /var/run/ambari-server
# ls -lart /var/run/ambari-server

Error-2). Database setup Issue.

Caused by: java.lang.RuntimeException: Error while creating database accessor
at org.apache.ambari.server.orm.DBAccessorImpl.<init>(DBAccessorImpl.java:120)

This indicates an issue with Ambari DB setup. So please let us know if you are running ambari server with default Embedded Postgres DB or you have configured Non Default DB?

Also please share the output of the following command:

# grep 'jdbc' /etc/ambari-server/conf/ambari.properties.

Thanks very much for your quick answer.

For your questions related to Error 1 :

I use Ambari server as a root.

The command "ls -ld /var/run/ambari-server" generates :

drwxr-xr-x 2 root root 40 oct. 28 16:32 /var/run/ambari-server

The command "ls -lart /var/run/ambari-server" generates :
