h1. Test Environment

h2. Virtual Machine description

Test machine is a virtual machine on a ProxMox environment.
Physically stored on inf-proxmox2
VM Name : sdo3
VM id : 801
memory : 32.00GB
CPU : 16 CPUs (4 X 4 cores)
Hard Disk 1 : 64 GB (OS + NetDRMS software) - stored on NFS-HA
Hard Disk 2 : 1 TB (Databases) - Stored localy

Not in HA configuration. VM Backup each day (for OS).

Guest OS : Debian 8.1
Guest kernel : Linux sdo3 3.16.0-4-amd64 #1 SMP Debian 3.16.7-ckt11-1 (2015-05-24) x86_64 GNU/Linux

h2. Manual install of postgresql

h3. Prerequisites

<pre>
# apt-get --purge remove postgresql*

# wget https://ftp.postgresql.org/pub/source/v9.4.4/postgresql-9.4.4.tar.gz

# tar -xzvf postgresql-9.4.4.tar.gz
</pre>

Before compiling, I verify that patch required by NetDRMS (voir [[ici|http://vso.stanford.edu/netdrms/pginst.html]]) was really present in source files :

_src/backend/utils/misc/guc.c_ and _src/bin/pg_dump/pg_dump.c_

<pre>
# apt-get update
# apt-get upgrade
# apt-get install gcc make libreadline-dev minizip
</pre>

h3. Installation

<pre>
# ./configure
# make
# su
# make install
# adduser postgres
</pre>

h3. Test database

<pre>
# mkdir /usr/local/pgsql/data
# chown postgres /usr/local/pgsql/data
# su - postgres
# /usr/local/pgsql/bin/initdb -D /usr/local/pgsql/data
# /usr/local/pgsql/bin/postgres -D /usr/local/pgsql/data >logfile 2>&1 &
# /usr/local/pgsql/bin/createdb test
# /usr/local/pgsql/bin/psql test
</pre>

h3. Shared postgresql library

<pre>
# vi /etc/ld.so.conf/libc.conf
</pre>
add :
<pre>
/usr/local/pgsql/lib
</pre>

h3. Boot start-up

We create an init script in order to start postgresql on boot

<pre>
# vi /etc/init.d/postgresql
</pre>

Content :

<pre>
#! /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.

h3. Install additional module

Nous avons besoin de dblink pour les trigger entre bases de données

<pre>
apt-get install postgresql-contrib
</pre>
