Hi dasgoll
I have installed postgresql-9.4 and did the following
service postgresql stop
service postgresql-9.4 initdb
service postgresql-9.4 start
sudo su - postgres
cd /var/lib/pgsql/9.4/data
vi postgresql.conf
change (uncomment):
listen_addresses = 'localhost' # what IP address(es) to listen on;
TO
listen_addresses = '*'
vi pg_hba.conf
change line to have md5:
replace with:
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
host all boss 0.0.0.0/0 md5
- restart:
sudo service postgresql-9.4 restart
However I was not able to login on ambari because I didn't tell ambari to use
postgresql-9.4. Can you please advice ?
Many thanks
Dragan
Although my pg_hba.conf was located in /etc/postgresql, this worked like a charm. Thank you!
