Habilitacion de puerto 5432

Habilitacion de puerto 5432

Buenos dias, estimados, tengo poca experiencia en estas lides de postgres y acabo de instalar un servidor con la version 8.1.17, pero no abre el puerto respectivo.

Cualquier ayuda agradecere

Problemas para conectar con el servidor

Hola,

Estoy trantando de conectar con el servidor una vez instalado el programa y realmente no me deja... me aparece el siguiente error, la verdad es que soy nuevo en el tema. Agradezco cualquier idea para solucionarlo.
Gracias

El servidor no escucha.

Could not connect to server: Conenection refused (0x0000274D/10061) Is the server running on host 12700.T and acepting TCP/IP connection on port 5432

PostgreSQL se puede acceder

PostgreSQL se puede acceder por medio de sockets ó/y via tcp/ip.

Por defecto y si no cambias la configuración suele escuchar solamente via sockets y localhost (127.0.0.1). El parámetro que define por donde se puede acceder a PostgreSQL es listen_addresses en el fichero de configuración postgresql.conf

Por defecto este parámetro está definido asi:

#listen_addresses = 'localhost'

Si quieres que se pueda acceder tambien desde el exterior conectandose a la IP de la máquina tendrás que cambiarlo a:

listen_addresses = 'localhost,IP_de_la_maquina'

Si quieres que se pueda acceder solamente via sockets, cambialo a:

listen_addresses = ''

Y si quieres que se pueda acceder por todas las IPs instaladas en la máquina:

listen_addresses = '*'

¿Es "12700.T" el nombre que te dice el fallo? ¿No será 127.0.0.1?

¿En qué sistema operativo te ocurre esto? En linux/unix puedes ver si tienes instalada la interfaz "loopback / lo:" (127.0.0.1/localhost) con el comando /sbin/ifconfig

¿Has cambiado el puerto por defecto (5432) por donde se puede acceder a PostgreSQL?

Problemas de conexión Postgree

En primer lugar darte las gracias por tu pronta respuesta,efectivamente el error que me comentas es el 127.0.0.1, trabajo con windows 2000. Entiendo lo que me comentas, pero tengo una duda, mi idea es conectarme con vía IP y con las que pueda tener en mi máquina. Me das unas instrucciones para cambiar en el archivo postgresql.conf la configuración que puede tener por defecto en este sentido.

Ahora mi pregunta es donde se cambia esta configuración, no he podido localizarlo.

Te comento que cuando he abierto el archivo postgresql.conf, en el Editor de configuración del servicio había varios servidores seleccionados (opciones), ahora solo he dejado 2 listen_addresses y port 5432.

Lo que no entiendo es donde tengo que escribir las instrucciones qeu me comentas.

Saludos y gracias, son mis primeros pasos con el programa y realmente llevo varios meses tratando de instalarlo pero no paso de este error,

Gracias,

windows - 127.0.0.1 y listen_addresses

Las opciones que te comento las tienes que cambiar en el fichero postgresql.conf. En este fichero *no* puedes tener más de una linea con el parametro listen_addresses ó port.

Borra todas las lineas que tengas con listen_addresses ó port y escribe estas dos lineas:

listen_addresses = '*'
port = 5432

Asegurate que *no* tengan un simbolo # al principio. No te olvides de parar y arrancar postgreSQL para que los cambios se instalen.

Si despues de esto te sigue apareciendo un error cuando intentes conectarte desde la misma maquina a 'localhost' (127.0.0.1), es que tienes un problema en la configuración de 'localhost' en tu maquina.

Suerte y ya contaras.

Una vez editado el fichero postgresql.conf

Hola, he podido editar el archivo postgresql.conf, la verdad es que es la primera vez que estoy editanto archivos y antes de empezar a borrar nada. He pensado que era mejor poder colgar el archivo como esta para que alguién que conoce del tema pueda ver si esta bien o conviene empezar a borrar...

Saludos y gracias

# 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 paramters can be changed at run time

sobre postgresql.conf

Esta perfecto para comprobar si todo funciona y para empezar a usar/'jugar' con PostgreSQL. Como está te tendria que arrancar y estar accesible via sockets, localhost (127.0.0.1) y la IP de red que tenga el servidor, todo ello por el puerto 5432.

Solamente listen_addresses y port están sin comentar, esto significa que los valores que tengan definido son los que se van a utilizar.

El resto de parametros tienen el simbolo # al principio de la linea, esto significa que estan comentados y que utilizarán los valores por defecto predefinidos en PostgreSQL.

En sistemas que se utilizan en producción con bases de datos grandes y muchos usuarios se tienen que cambiar mas parametros, pero esto es otro tema. A ti lo que te interesa es conseguir arrancar / conectarte a PostgreSQL.

No conecta

Hola después de realizar estas revisiones la verdad es que no me deja conectar, he revisado el tema del firewal para ver si hay algo marcado pero tampoco... gracias, trataré de seguir probando...

¿Qué programa utilizas para conectar?
¿Cual es el comando *completo* que utilizas para intentar conectar?
Y ¿Cual es el error *completo* que te da cuando falla?

Hola, He tratado de volver a

Hola,
He tratado de volver a instalar el programa y nada..
Adjunto el error..

Could not connect to server
Connection refused (0x0000274D/D10061) Is the server running on host "127.0.0.1" and accepting TCP/IP connections on port 5432?

Al volver a instalar el programa hay un momento en el que da problemas y creo que hay es donde puede estar el problema.. al reinstalar todo

Utilizo el PostgreSQL 8.2
Tengo Windows 2000
Explorer
Firewell quitado
Antivirus Karspersky

Cualquier idea se agradece, aunque la verdad ya estoy a punto de desistir, llevo así con este programa desde enero..

No obstante gracias por haber contestado y si en alguna de estas reinstalaciones lo consigo os comento

Comprueba fichero log ++

Si te sale ese error con el fichero postgresql.conf que nos enseñastes, es porque existe otro problema. Probablemente ó postgreSQL no ha podido arrancar por alguna razón ó tienes problemas con la configuración de red de tu máquina y no tienes instalado la IP 127.0.0.1.

¿Qué fallo te da cuando intentas reinstalar?

Comprueba tres cosas:

  • El fichero log de PostgreSQL: Lo encontraras en el directorio pg_log donde hayas inicializado tu directorio de datos bajo el nombre postgresql-%Y-%m-%d_%H%M%S.log. ¿Hay algun fallo registrado despues de arrancar postgres, que nos indique que algo ha fallado?
  • Configuración de red de tu máquina: Creo que en windows puedes utilizar "Start-->Programs-->Accessories-->Command prompt" ..... escribe ipconfig /all y comprueba el resultado. Intenta conectarte a la IP que te muestre este comando y comprueba que es lo que ocurre
  • En esta misma ventana ejecuta el comando ping 127.0.0.1. ¿Qué es lo que ocurre?

Ya contaras ...
