In going thru the Data Installation Guide version 1.7.0 I got up to section 1.1.3 on installation of postgres database. I followed it to install the DB with :

yum install postgresql91-server

But the following commands did not work :

• service postgresql91 initdb
• service postgresql91 on
• service postgresql91 start

I actually had to run:

 
[root@localhost init.d]# service postgresql-9.1 initdb
Initializing database: [ OK ]
[root@localhost init.d]# service postgresql-9.1 on
Usage: /etc/init.d/postgresql-9.1 {start|stop|status|restart|condrestart|try-restart|reload|force-reload|initdb}
[root@localhost init.d]# service postgresql-9.1 start
Starting postgresql-9.1 service: [ OK ]
[root@localhost init.d]#

Note that the second command did not run nor was it supported by the service command .

Thanks
