A. Installing PostGres

A.1. Download and install the source: postgresql-8.2.3.tar.gz

[root@rupert-linux routing]tar -xvzf postgresql-8.1.2.tar.gz
[root@rupert-linux routing]LDFLAGS=-lstdc++
[root@rupert-linux routing]./configure --prefix=/usr/local/pgsql --with-perl --with-python --with-krb5 --with-openssl
[root@rupert-linux routing]make
[root@rupert-linux routing]make install
 
A.2. Post Compile Operations:
 
[root@rupert-linux routing]/usr/sbin/adduser postgres
 
[root@rupert-linux routing]mkdir /usr/local/pgsql/data
 
[root@rupert-linux routing]chown postgres /usr/local/pgsql/data/
 
[root@rupert-linux routing]su - postgres
 
[root@rupert-linux routing]/usr/local/pgsql/bin/initdb -D /usr/local/pgsql/data/

Note: If youre default locale is not EN, say chinese, then you would get:

The files belonging to this database system will be owned by user “postgres”.
This user must also own the server process.

The database cluster will be initialized with locale zh_CN.GB18030.
initdb: could not find suitable encoding for locale “zh_CN.GB18030″

A.3. Edit environment variables. Add the ff to your .bash_profile

[root@rupert-linux routing] vi /root/.bash_profile
PATH=$PATH:$HOME/bin:/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/local/sbin:/usr/local/mysql/bin:$JAVA_HOME/bin:/usr/local/pgsql/bin
export PGLIB=/usr/local/pgsql/lib
export PGDATA=/usr/local/pgsql/data
export PGPORT=5432
export PGOPTS="-i"

A.4. Start PostGres Automatically on Startup. Postgres Startup Script

[root@rupert-linux routing]touch /etc/init.d/postgresql
[root@rupert-linux routing] vi /etc/init.d/postgresql

PostGres Startup Script

#!/bin/sh
# postgresql    This is the init script for starting up the PostgreSQL
#               server
 
# chkconfig: - 85 15
# description: Starts and stops the PostgreSQL backend daemon that handles all database requests.
# processname: postmaster
# pidfile: /usr/local/pgsql/data/postmaster.pid
#
 
# Source function library.
. /etc/rc.d/init.d/functions
 
# Get config.
. /etc/sysconfig/network
 
# Check that networking is up.
# Pretty much need it for postmaster.
[ ${NETWORKING} = "no" ] && exit 
 
[ -f /usr/local/pgsql/bin/postmaster ] || exit 
 
# See how we were called.
case "$1" in
start)
pid=`pidof postmaster`
if [ $pid ]
then
echo "Postmaster already running."
else
echo -n "Starting postgresql service: "
su -l postgres -c '/usr/local/pgsql/bin/pg_ctl -o -i -D /usr/local/pgsql/data/ -l /usr/local/pgsql/data/logfile start'
sleep 1
echo
exit
fi
;;
 
stop)
echo -n "Stopping postgresql service: "
killproc postmaster
sleep 2
rm -f /usr/local/pgsql/data/postmaster.pid
echo
;;
 
restart)
$0 stop
$0 start
;;
 
*)
echo "Usage: postgresql {start|stop|restart}"
exit 1
esac
 
exit

A.5. PostGres Testing

[root@rupert-linux routing]# su - postgres
[postgres@rupert-linux ~]$ /usr/local/pgsql/bin/createdb test
[postgres@rupert-linux ~]$ /usr/local/pgsql/bin/psql test

B. Installing PostGIS.

B.1. Download Geos

[root@rupert-linux /]# bzip2 -d geos-3.0.0rc4.tar.bz2
[root@rupert-linux /]# tar -xvf geos-3.0.0rc4.tar
[root@rupert-linux /]# ./configure
[root@rupert-linux /]# make
[root@rupert-linux /]# make install

B.2. Download PostGIS.
