To start and stop PostgreSQL Server, create the postgresql script file, touch /etc/rc.d/init.d/postgresql and add:
#! /bin/sh
# postgresql This is the init script for starting up the PostgreSQL
# server
# chkconfig: 345 85 15
# description: Starts and stops the PostgreSQL backend daemon that handles \
# all database requests.

# Check that networking is up.
# Pretty much need it for postmaster.
[ ${NETWORKING} = "no" ] && exit 0
[ -f /usr/bin/postmaster ] || exit 0
# This script is slightly unusual in that the name of the daemon (postmaster)
# is not the same as the name of the subsystem (postgresql)
# See how we were called.

Now, make this script executable and change its default permissions:
[root@deep] /# chmod 700 /etc/rc.d/init.d/postgresql
|
Create the symbolic rc.d links for PostgreSQL with the command:
[root@deep] /# chkconfig --add postgresql
|
Start your new PostgreSQL server manually with the following command:
[root@deep] /# /etc/rc.d/init.d/postgresql start
|
Checking postgresql installation: looks good!
Starting postgresql service: postmaster [22401]
