Install confluence and connect to running PostgreSQL DB

Hans-Georg Emberger

I have installed confluence, postgreSQL and the database for confluence.
When I try to connect, test is not successful

Can't reach database server or port

SQLState - 08001
org.postgresql.util.PSQLException: Connection to mail.nochricht.de:5432 refused. Check that the hostname and port are correct and that the postmaster is accepting TCP/IP connections.

On the server I have opened the ufw firewall to allow 8090 and tcp/5432

Whsat else could be the missing piece?

Postgres has a pg_hba.conf file which controls security and I always get wrong.

That has to be configured to allow connections from your Confluence server, and with the right type of password.

For example, this one is one I have at home, configured for "any machine on my local network" by the last line. Before I added that, my Confluence got the same message as you.

nic@stannis:~$ sudo cat /etc/postgresql/9.4/main/pg_hba.conf
[sudo] password for nic:
# PostgreSQL Client Authentication Configuration File

Hi Nic, thank you for the answer ... still did not find the settings which work ..
What is the 24 behind the slash?

Nic Brough -Adaptavist-

It means "look at the first 24 bits of the address before the /" - translates to "192.168.1. (any number from 1 to 255)"

You did alter the IP range there to match your network? And restart postgres?

You can just put in the raw IP address of the server (Just 192.168.1.42 for example), which is more secure as it means "only that server".

But, if it's not the pg_hba.conf file refusing you access, it could be something else on your network.

Ok got it.

In my situation confluence runs on a vServer and I connect via the internet.
So the access should be direct from confluence on this server to the db on this server
host all all localhost md5
but still not working ...
