Install PostgreSQL 9.2 on Fedora 19 y 18

Note: If you are upgrading PostgresSQL (from earlier version), then make sure that you backup (dump and copy) your database and configs.

Install PostgreSQL 9.2.1 Database Server on Fedora 18

 

Change root user
su -

Exclude Fedora own PostgreSQL Packages
Add exclude to /etc/yum.repos.d/fedora.repo file [fedora] section:
[fedora]
...
exclude=postgresql*

Add exclude to /etc/yum.repos.d/fedora-updates.repo file [updates] section:
[updates]
...
exclude=postgresql*

Install PostgreSQL 9.2 Repository
rpm -Uvh http://yum.postgresql.org/9.2/fedora/fedora-18-x86_64/pgdg-fedora92-9.2-6.noarch.rpm

Para Fedora 19
rpm -Uvh http://yum.postgresql.org/9.2/fedora/fedora-19-x86_64/pgdg-fedora92-9.2-6.noarch.rpm

Ésta es una forma de llamar el comando, pero se puede personalizar segun sean las caracteristicas de su Sistema Operativo y Arquitectura, obteniendo la información de: http://yum.postgresql.org/9.2/fedora/

Install PostgreSQL 9.2 with YUM
yum install postgresql postgresql-server postgresql-contrib

Configure PostgreSQL 9.2

Initialize Cluster with initdb Command
Here is multiple alternatives howto do this (like service postgresql-9.x initdb, /etc/init.d/postgresql-9.x initdb) and postgresql-setup initdb, so that’s why I use here universal PostgreSQL initdb method, which should work with Fedora 18, CentOS/Red Hat (RHEL)/Scientific Linux (SL) 6.3/5.8:
su - postgres -c /usr/pgsql-9.2/bin/initdb

Set PostgreSQL Server to Listen Addresses and Set Port
Open /var/lib/pgsql/9.2/data/postgresql.conf file, and add/uncomment/modify following:
listen_addresses = '*'
port = 5432

If you want just localhost setup, then use following:
listen_addresses = 'localhost'
port = 5432

Or if you want use specific ip, then use following:
listen_addresses = '192.1.2.33'
port = 5432

Set PostgreSQL Permissions

Modify PostgreSQL /var/lib/pgsql/9.2/data/pg_hba.conf (host-based authentication) file:

# Local networks
host all all xx.xx.xx.xx/xx md5
# Example
host all all 10.20.4.0/24 md5
# Example 2
host test testuser 127.0.0.1/32 md5

Modify PostgreSQL /var/lib/pgsql/9.2/data/pg_hba.conf (host-based authentication) file:
# Local networks
host all all xx.xx.xx.xx/xx md5
# Example
host all all 10.20.4.0/24 md5
# Example 2
host test testuser 127.0.0.1/32 md5

You can find more examples and full guide from PostgreSQL pg_hba.conf manual -> http://www.postgresql.org/docs/9.2/static/auth-pg-hba-conf.html

Start PostgreSQL Server and Autostart PostgreSQL on Boot

Despues del siguiente bloque, veremos llamar a postgresql-9.2.service pero ¿De donde obtenemos el nombre del servicio?, para obtenerlo acceder a la siguiente direccion:
]# pwd
/usr/lib/systemd/system
]# ls pos*
postgresql-9.2.service
Entonces ejecutar:
## Start PostgreSQL 9.2 ##
systemctl start postgresql-9.2.service

## Start PostgreSQL 9.2 on every boot ##
systemctl enable postgresql-9.2.service

Create Test Database and Create New User
Change to postgres user
su postgres

Create test database (as postgres user)
createdb test

Login test database (as postgres user)
psql test

Create New “testuser” Role with Superuser and Password
CREATE ROLE testuser WITH SUPERUSER LOGIN PASSWORD 'test';

Test Connection from localhost (as Normal Linux User)
psql -h localhost -U testuser test

De ésto modo ya tengo instalado PostgreSQL, pero necesito de una herramienta gráfica, por lo que recurro a instalar:
yum -y install pgadmin3

Aquí una imagen ya de nuestro gestor instalado.
