Где мои файлы postgres * .conf?

Ubuntu 13.04, установленный с помощью программного центра:

Место для моего:

/etc/postgresql/9.1/main/postgresql.conf

Run

sudo updatedb

за которым следует

locate postgresql.conf

Где мои файлы postgres *.conf?

Запросить базу данных с помощью SQL-запроса:

SHOW config_file;

У вас может возникнуть проблема с поиском postgresql.conf, потому что он принадлежит postgres, а не root.

Вот где моя находится на Fedora 17:

[root@defiant /]# ll /var/lib/pgsql/data/postgresql.conf 

Обратите внимание, что он принадлежит postgres:

-rw------- 1 postgres postgres 19332 Oct 14 09:38 
     /var/lib/pgsql/data/postgresql.conf

У него есть разрешение 600, которое объясняет, почему вам сложно найти его при поиске файлов. Местоположение postgresql.conf будет отличаться в зависимости от того, какую операционную систему вы используете.

# 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

Чтобы получить местоположение файла pg_hba.conf, вы также можете запросить базу данных, например

SHOW hba_file;

Вы должны получить что-то вроде

            hba_file             
---------------------------------
 /var/lib/pgsql/data/pg_hba.conf
(1 row)

На Mac (Postgres установлен с помощью brew):

/usr/local/Cellar/postgresql/9.3.3 > bin/postgres -D/usr/local/var/postgres/

В Fedora 20

$ cd /var/lib/pgsql/data
$ ls -ltr *.conf

-rw-------. 1 postgres postgres 20453 Jan 18 23:22 postgresql.conf
-rw-------. 1 postgres postgres  1636 Jan 18 23:22 pg_ident.conf
-rw-------. 1 postgres postgres  4476 Jan 18 23:22 pg_hba.conf

В Mac OS X:

sudo find / -name postgresql.conf 

Вы можете найти другие файлы conf с помощью следующей команды:

sudo find / -name pg\*.conf

Примечание: смотрите использование, используя man:

man find

Ответ может заключаться в том, что вы еще не инициализировали базу данных. После установки postgres, но до инициализации базы данных, файлы postgres *.sql будут отсутствовать. После инициализации базы данных появятся файлы postgres *.sql. (Centos 6, Postgres 9.3, продемонстрированный здесь)

[root@localhost /]# yum -y install postgresql93 postgresql93-server 
[root@localhost /]# ls /var/lib/pgsql/9.3/data/
[root@localhost /]#
[root@localhost /]# service postgresql-9.3 initdb
Initializing database:                                     [  OK  ]
[root@localhost /]# ls /var/lib/pgsql/9.3/data/
base         pg_ident.conf  pg_serial     pg_subtrans  pg_xlog
global       pg_log         pg_snapshots  pg_tblspc    postgresql.conf
pg_clog      pg_multixact   pg_stat       pg_twophase
pg_hba.conf  pg_notify      pg_stat_tmp   PG_VERSION
[root@localhost /]#

Для CentOS 6 и 7 и postgresql 9.2 (и ниже, я полагаю, возможно, Fedora и Redhat):

/var/lib/pgsql/data

Для CentOS 6 и 7 postgresql 9.3 или 9.4 (и выше, я полагаю):

/var/lib/pgsql/9.3/data
/var/lib/pgsql/9.4/data

Для Ubuntu 14 и postgresql 9.3:

/etc/postgresql/9.3/main/postgresql.conf

Для Debian 9 я нашел свой, используя ответ Franke Heikens - $/etc/postgresql/9.6/main/postgresql.conf

Поскольку у меня нет доступа к учетной записи postgres (поэтому не могу запустить SHOW config_file), и мои postgres установлены в Windows, ни один из ответов не помог мне, поэтому я делюсь своим файловым адресом для будущих читателей Windows

C:\Program Files\PostgreSQL\9.5\data

Помимо прямого ответа, вы, вероятно, захотите проверить документы о настройке Postgres расположение файлов.

В большинстве случаев: под $PGDATA, который обычно /var/lib/postgresql/data или что-то подобное (по крайней мере, это путь по умолчанию, если вы используете Docker images).

В CentOS 7 с PostgreSQL 9.4 он находится в следующем каталоге:

/var/lib/pgsql/9.4/data

Я могу видеть это, когда я зарегистрирован как root.

Мне нравится этот поток, потому что он документирует местоположения по умолчанию для различных файлов postgresql.conf на разных архитектурах...

Однако, я также попал в беду, полагаясь на эти значения по умолчанию при установке, где они указали альтернативные местоположения. Один из способов узнать, где находится конкретный файл конфигурации, напрямую запросив базу данных:

select * from pg_settings where name='config_file'

Отбросьте предложение where, чтобы просмотреть все настройки, которые также могут быть освещены, потому что они показывают, где находятся каталоги данных, pg_hba.conf и т.д.

Если вы следовали за белой бумагой, выпущенной Amazon для установки Postgresql на AWS, которая включала создание каталога/data/на файловой системе, смонтированной на отдельном томе EBS, тогда ваш файл postgresql.conf находится в /data/

Из которого я заключаю, что файл создается во время инициализации каталога данных и находится в корне каталога данных. Для установки по умолчанию это выглядит как /var/lib/pgsql/data, но не если вы перемещаете данные dir

Я боюсь, что это еще не все. Я сделал все хорошие вещи, описанные выше в Windows, и база данных не запускалась. По-прежнему остается загадкой, почему переход на другой PGDATA является "сложным"

В любом случае единственным решением этой проблемы было удаление старого каталога PGDATA. Затем переустановите postgresql. Если старая по умолчанию папка все еще висит вокруг или не пуста, (Windows) устанавливает barfs. Не совсем до нуля? Что случилось с приятным dbadmin gui?
