Compilation Installation et Configuration de Postgresql

Installation et configuration d'un serveur de base de données Postgresql en passant par sa compilation.

Installation de postgresql par compilation:

adduser postgres

./configure --prefix=/opt/postgresql831 --with-openssl

mkdir /opt/postgresql831/data

cd /opt/

ln -s postgresql831 postgresql

chown -R postgres:postgres /opt/postgresql831/data

/opt/postgresql831/bin/initdb -D /opt/postgresql831/data

touch /var/log/postgresql.log

port 5432

démarrer le serveur :

/opt/postgresql831/bin/postgres -D /opt/postgresql831/data >/var/log/postgresql.log &

le script d'init.d se trouve ici /opt/SOURCES/postgresql-8.3.1/contrib/start-scripts/linux

le modifier -> changer /usr/local/pgsql par /opt/postgresql

INIT.D :


#! /bin/sh

# chkconfig: 2345 98 02
# description: PostgreSQL RDBMS

# This is an example of a start/stop script for SysV-style init, such
# as is used on Linux systems.  You should edit some of the variables
# and maybe the 'echo' commands.
#
# Place this file at /etc/init.d/postgresql (or
# /etc/rc.d/init.d/postgresql) and make symlinks to
#   /etc/rc.d/rc0.d/K02postgresql
#   /etc/rc.d/rc1.d/K02postgresql
#   /etc/rc.d/rc2.d/K02postgresql
#   /etc/rc.d/rc3.d/S98postgresql
#   /etc/rc.d/rc4.d/S98postgresql
#   /etc/rc.d/rc5.d/S98postgresql
# Or, if you have chkconfig, simply:
# chkconfig --add postgresql
#
# Proper init scripts on Linux systems normally require setting lock
# and pid files under /var/run as well as reacting to network
# settings, so you should treat this with care.

prefix=/usr/local/pgsql

# Data directory
PGDATA="/opt/postgresql/data"

# Who to run the postmaster as, usually "postgres".  (NOT "root")
PGUSER=postgres

# Where to keep a log file
PGLOG="/var/log/posgresql.log"

## STOP EDITING HERE

# The path that is to be used for the script
PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/opt/postgresql/bin

# What to use to start up the postmaster (we do NOT use pg_ctl for this,
# as it adds no value and can cause the postmaster to misrecognize a stale
# lock file)

# What to use to shut down the postmaster
PGCTL="$prefix/bin/pg_ctl"

set -e

# Only start if we can find the postmaster.

# Parse command line parameters.
case $1 in

        echo -n "Starting PostgreSQL: "
        su - $PGUSER -c "$DAEMON -D '$PGDATA' &" >>$PGLOG 2>&1

        # Print help
        echo "Usage: $0 {start|stop|restart|reload|status}" 1>&2
        exit 1
        ;;
esac

exit 0

En ce qui conserne le rc3.d et rc5.d bien penser à faire des K pour un arret propre.

modifier si besoin /opt/postgresql/data/postgresql.conf

Mot de passe :

psu - postgres 
psql -d template1 -c "ALTER USER postgres WITH PASSWORD 'le_mdp_postgres'" 
exit

Puis redémarrer le service pour que le nouveau mot de passe soit prit en compte.
