[opennms-devel] PostgreSQL problem - Could not get an administrative connection to the database

Hi all,


I am in the process of installing OpenNMS on my CentOS machine. Followed the instruction provided on this website to install OpenNMs: http://www.opennms.org/index.php/Installation:Yum
 

As a part of this process, I installed postgresql-server using yum command and when I was configuring it, I ran into some problem. Just like the instruction has suggested, at some point, had to edit pg_hba.conf and postgresql.conf located in /var/lib/pgsql/data directory. 

- In pg_hba.conf, I replaced all ident sameuser with trust to allow postgres to authenticate, this is how it looks like now:


# TYPE  DATABASE    USER        CIDR-ADDRESS          METHOD

# "local" is for Unix domain socket connections only
local   all         all                               trust
# IPv4 local connections:
host    all         all         127.0.0.1/32          trust
# IPv6 local connections:
host    all         all         ::1/128               trust


- In postgresql.conf, I made some changes to allow TCP/IP connections:
listen_addresses = 'localhost'

After
that, every time I try to start the postgres, it fails to start the service. If I replace 'localhost' with '*' to listen on all addresses, I can start postgres service with no problem.

But
when I get to the step where I should initialize OpenNMS and database
(I already created a database called opennms) by running $OPENNMS_HOME/bin/install -dis command, get a long error message which I paste the important lines below. 

Just to test, I ping
localhost which fails (ping 127.0.0.1 works fine, so I tried replacing the
listen to localhost with listen to the IP but no luck).

I created my
own log file here: /var/log/postgres.log so that it shows me what the problem really is...

This is part of the error message I get when trying to run the $OPENNMS_HOME/bin/install -dis command I mentioned above:

Could not get an administrative connection to the database.  Is the database running, 
listening for TCP connections, and allowing us to connect and authenticate from localhost? 
Tried connecting to database specified by data source SimpleDataSource
[URL='jdbc:postgresql://localhost:5432/template1', driver class='org.postgresql.Driver', 
properties: user='postgres', password='']

This is my opennms-datasource.xml file:
<?xml version="1.0" encoding="UTF-8"?>
<datasource-configuration xmlns:this="http://xmlns.opennms.org/xsd/config/opennms-datasources"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

                      http://www.opennms.org/xsd/config/opennms-datasources.xsd ">
  <jdbc-data-source name="opennms"
                    database-name="opennms"
                    class-name="org.postgresql.Driver"
                    url="jdbc:postgresql://localhost:5432/opennms"
                    user-name="opennms"
                    password="opennms" />

  <jdbc-data-source name="opennms-admin"
                    database-name="template1"
                    class-name="org.postgresql.Driver"
                    url="jdbc:postgresql://localhost:5432/template1"
                    user-name="postgres"
                    password="" />
</datasource-configuration>
Am I missing something? Please help! 

Thanks in advance,honia
