Bonjour tout le mode, je cherche à modifier le port d'écoute par défaut de postgresql à 5433. J'ai changé le port dans /etc/postgresql/8.4/main/postgresql.conf
#port = 5433 # (change requires restart)
J'ai besoin de vos suggestions s'il vous plaît.

[punkoff]

enlevez le # devant "port".

Sinon ca reste en commentaire

[perle1988]

Je vien d'enlever mais toujours le même problème

[MarcS]

Bonjour,
Avez vous pensé à relancer postgre ?
Bonne journée
MS

[perle1988]

Oui, j'ai relancé /etc/init.d/postgresql restart . Et même j 'ai fermé et l'ouvrir de nouveau mais toujours le même problème

[Arkhena]

Bonjour,

S'il s'agit de l'installation d'une autre version de postgreSQL sur la même machine, êtes-vous sûr que /etc/init.d/postgresql restart redémarre la bonne instance ?

Cordialement,

Arkhena

[perle1988]

Oui, il démarre la bonne instance

[Arkhena]

C'est pourtant bien ce qu'il faut faire...

Petite question con (je m'en excuse) : s'il y a plusieurs instances sur la même machine, avez-vous bien modifié le bon fichier postgresql.conf ?

Dernière question con : comment regardez-vous sur quel port tourne l'instance ?

En désespoir de cause, pouvez vous poster le fichier postgresql.conf (ou au moins la partie connection settings) ?

Cordialement,

Arkhena

C'est dans la propriété du srveur que je configure le port 5433 et je définit la hôte ausssi.
Voilà un extrait du fichier postgresql.conf qui est normalement configuré avec le port 5433 mais il fonctionne avec 5432 :

# -----------------------------
# PostgreSQL configuration file
# -----------------------------
#
# This file consists of lines of the form:
#
# name = value
#
# (The "=" is optional.) Whitespace may be used. Comments are introduced with
# "#" anywhere on a line. The complete list of parameter names and allowed
# values can be found in the PostgreSQL documentation.
#
# The commented-out settings shown in this file represent the default values.
# Re-commenting a setting is NOT sufficient to revert it to the default value;
# you need to reload the server.
#
# This file is read on server startup and when the server receives a SIGHUP
# signal. If you edit the file on a running system, you have to SIGHUP the
# server for the changes to take effect, or use "pg_ctl reload". Some
# parameters, which are marked below, require a server shutdown and restart to
# take effect.
#
# Any parameter can also be given as a command-line option to the server, e.g.,
# "postgres -c log_connections=on". Some parameters can be changed at run time
# with the "SET" SQL command.
#
# Memory units: kB = kilobytes Time units: ms = milliseconds
# MB = megabytes s = seconds
# GB = gigabytes min = minutes
# h = hours
# d = days

D'après le chemin du postgresql.conf, ça ressemble à une distribution debian ou ubuntu.
Si c'est bien le cas, pourrais-tu donner le résultat de la commande suivante:

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

 pg_lsclusters

ainsi que, tant qu'à faire:

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

 sudo netstat -tlnp

(ports tcp ouverts en écoute)

[perle1988]

L résultat de la première commande :

Version Cluster   Port Status Owner    Data directory                     Log file
8.4     main      5432 down   postgres /var/lib/postgresql/8.4/main       /var/log/postgresql/postgresql-8.4-main.log

Le résultat de la deuxième commande

Proto Recv-Q Send-Q Local Address           Foreign Address         State       PID/Program name

Effectivement ça montre que le changement de port n'est pas pris en compte, à part le fait que le service n'est pas lancé. Ce qui est curieux est que pg_lsclusters va le lire directement dans le fichier en question.
Par exemple chez moi pg_clusters sur une base 8.4 arrêtée donne:

Version Cluster   Port Status Owner    Data directory                     Log file
8.4     main      5432 down   postgres /var/lib/postgresql/8.4/main       /var/log/postgresql/postgresql-8.4-main.log

Maintenant si j'édite /etc/postgresql/8.4/main/postgresql.conf et que je change le port dans le fichier sans rien faire d'autre j'obtiens immédiatement le résultat différent:

$ pg_lsclusters
Version Cluster   Port Status Owner    Data directory                     Log file
8.4     main      5433 down   postgres /var/lib/postgresql/8.4/main       /var/log/postgresql/postgresql-8.4-main.log

et là il suffit de lancer

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

/etc/init.d/postgresql-8.4 start

pour démarrer sur le nouveau port.

Je ne vois pas ce qui diffère par rapport à ce que tu fais.
