How to configure PostgreSQL database for deploying alfresco on tomcat 8?

Question

I have built alfresco(version 5.2) from source on ubuntu 16.04. I want to deploy alfresco on tomcat 8. The deployment is successful however the PostgreSQL database is not getting configured as required. I have followed the steps as given in http://docs.alfresco.com/5.1/tasks/postgresql-config.html

I observe the home page as given in image alfresco_page

Am I missing onto something here that the PostgreSQL database is not getting configured. Is there any other configuration that needs to be done that I have missed ?

UPDATE

The alfresco.log gave me this

Answer 1

Things to check:

1. Is postgres running (ps -ef|grep postgres)?
2. Can you use psql to connect to postgres using the db.name, db.username, and db.password that are configured in alfresco-global.properties?
3. Did you follow the step in the docs about editing pg_hba.conf to make sure that postgres is configured to allow password based authentication?

Also, it is exceedingly rare to need to build Alfresco from source unless you are making changes to the low-level classes themselves, which is not recommended.
