Configure Postgres to Allow Remote Connections

It is critical that you configure Postgres to allow remote connections before you deploy a cluster. If you do not perform these steps in advance of installing your cluster, the installation fails.

Open /var/lib/pgsql/9.6/data/pg_hba.conf and update to the following

# "local" is for Unix domain socket connections only
local all all trust


# IPv4 local connections:
host all all 0.0.0.0/0 trust 


# IPv6 local connections: 
host all all ::/0 trust

Open /var/lib//pgsql/9.6/data/postgresql.conf and update to the following:
```
listen_addresses = '*'
```

Restart Postgres:

systemctl stop postgresql-9.6.service
systemctl start postgresql-9.6.service
