Installing Postgres on Red Hat

By default, Red Hat installs Postgres. But surprisingly, the Postgres cannot be started by default. I guess it's not Red Hat's issue, but it's Postgres install issue. 

Here's the fix for all you care: 

1. create the data folder: 

    sudo mkdir -p /var/lib/pgsql/data

2. change ownership of the folder to user postgres

    sudo chown postgres /var/lib/pgsql/data

3. logon to user postgres: 

    sudo -i -u postgres

4. create the db: 

    initdb -D '/var/lib/pgsql/data'

5. start the db! 

    sudo service postgresql start

You're welcome.
