First time installation, not working

Hello,

I am attempting to install Postgresql for the first time.

The installation will be for Zabbix NMS.

I have installed pgsql 9.2 on Centos 6.3.

I set up an access right to pgsql by adding this line to /var/lib/pgsql/data/pg_hba.conf:

local zabbix zabbix md5

I then created a user in pgsql and a database for zabbix:

su - postgres

psql

CREATE USER zabbix WITH PASSWORD 'abc123';
CREATE DATABASE zabbix OWNER zabbix;
\q
exit

Finally, I try load some schema data via psql:

[root@zabbix lib]# cd /usr/share/zabbix-postgresql
[root@zabbix zabbix-postgresql]# cat schema.sql | psql -U zabbix zabbix
psql: FATAL: Peer authentication failed for user "zabbix"
[root@zabbix zabbix-postgresql]# cat schema.sql | psql -U zabbix zabbix -W
Password for user zabbix:
psql: FATAL: Peer authentication failed for user "zabbix"
[root@zabbix zabbix-postgresql]#

I have tried many permutations of the pg_hba.conf file but cannot find one the allows the zabbix user to "log in" or access the database successfully.

Can someone help me understand what I don't have configured correctly?

Thanks for any and all help that you can give.
