+----------------------------------
+installing and setting up a new db
+----------------------------------
+You will need sudo on that machine.
+
+- install postgres: 
+sudo yum install postgresql
+sudo yum install postgresql-server
+
+postgres tends to install its files under the username postgres. You should therefore create and use this user for the steps below. Specifically you need access to /var/run/postgresql/
+
+- make a directory for posgres data: 
+mkdir -p /usr/local/pgsql/data
+
+- Create a database cluster (file structure) 
+initdb -D /usr/local/pgsql/data
+
+- Initialise the server (I think I only need to do the second of these things) 
+postmaster -D /usr/local/pgsql/data >logfile 2>&1 &
+postgres -D /usr/local/pgsql/data &
+
+- create database: 
+createdb <db_name>
+
+- To restart the server (after shutting down for example)
+su - postgres
+pg_ctl start -D /usr/local/pgsql/data       
+-----------------------------------
+
+Configuring
+
+The config files will be inside the database cluster directory you created above (so /usr/local/pgsql/data/ in the example).
+
+There are two main config files, both in the above dir.
+
+pg_hba.conf (the client authentication configuration file)
+postgresql.conf (all sorts of things)
+
+You need to explicity allow for external hosts to connect to the database:
+
+pg_hba.conf:
+# IPv4 local connections:
+host    all             all             192.171.161.1/24         trust
+
+postgresql.conf
+listen_addresses = '*'
+
+pg_ctl is a utility for monitoring and controlling a posgreSQL server
+Check server status:
+pg_ctl status -D /usr/local/pgsql/data       
+pg_ctl: server is running (PID: 29763)
