我的postgres * .conf文件在哪里？

我最近在更新后在我的Ubuntu 8.04上重新安装了postgresql 8.3。 使用EnterpriseDB包。 我可以在本地连接到数据库，我看到系统数据库postgres，但我无法configuration它，因为我找不到configuration文件。 search整个硬盘驱动器，只find像pg_hba.conf.sample这样的示例

postgres * .conf文件在哪里？

Answer 1

或者询问你的数据库：

 SHOW config_file; 

Answer 2

跑

 sudo updatedb 

其次是

 locate postgresql.conf 

Answer 3

使用软件中心安装Ubuntu 13.04 ：

我的位置是：

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

Answer 4

我的postgres * .conf文件在哪里？

使用sql查询来查询数据库：

 SHOW config_file; 

您可能无法findpostgresql.conf的原因是因为它由postgres拥有，而不是root。

这里是我在Fedora 17上的地方：

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

注意它由postgres拥有：

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

它有权限600，这就解释了为什么你很难用文件searchfind它。 postgresql.conf的位置将根据您所使用的操作系统而有所不同。

这里是我的内容：

 # ----------------------------- # 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, eg, # "postgres -c log_connections=on".

Answer 5

在Mac上（使用brew安装Postgres）：

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

Answer 6

为了得到pg_hba.conf文件的位置，你也可以像查询数据库一样

 SHOW hba_file; 

你应该得到类似的东西

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

Answer 7

在Fedora 20上

 $ 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 

Answer 8

对于CentOS 6和7以及postgresql 9.2（以下，我想，也可能是Fedora和Redhat）：

/var/lib/pgsql/data

对于CentOS 6和7 postgresql 9.3或9.4（及以上，我想）：

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

对于Ubuntu 14和PostgreSQL 9.3：

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

Answer 9

答案可能是你还没有初始化数据库。 安装postgres之后，在初始化数据库之前，postgres * .sql文件将不存在。 初始化数据库后，将出现postgres * .sql文件。 （Centos 6，Postgres 9.3在这里展示）

 [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 /]# 

Answer 10

由于我无权访问postgres帐户（所以无法运行SHOW config_file ），并且我的postgres安装在Windows上，所有的答案都没有帮助我，所以我将为未来的Windows读者共享我的文件位置：

C:\Program Files\PostgreSQL\9.5\data

Answer 11

在使用PostgreSQL 9.4的CentOS 7中，它位于以下目录中：

 /var/lib/pgsql/9.4/data 

我以root身份login时可以看到它。

Answer 12

恐怕这是另一个无法回答的问题。 我在Windows上完成了上述所有的好事，数据库无法启动。 为什么转向不同的PGDATA是一个“挑战”

无论如何，这个问题唯一的解决办法是删除旧的PGDATA目录。 然后重新安装postgresql。 如果旧的默认文件夹仍然悬挂或非空，（Windows）安装barfs。 不是真的要抓挠吗？ 什么事情发生在一个很好的dbadmin gui？

Answer 13

如果您遵循Amazon提供的在AWS上安装Postgresql的白皮书，其中包括在安装在单独的EBS卷上的文件系统上创build/ data /目录，那么您的postgresql.conf文件位于/ data /

从中我得出结论，该文件是在数据目录初始化期间创build的，并驻留在数据目录的根目录中。 对于默认安装，这看起来是/ var / lib / pgsql / data，但是如果您移动了数据目录，则不会

Answer 14

我喜欢这个线程，因为它logging了各种架构上各种postgresql.conf文件的默认位置。

但是 ，我也遇到了麻烦，依靠那些指定了替代地点的安装的默认设置。 通过直接查询数据库来找出特定configuration文件的位置的一种方法是：

select * from pg_settings where name='config_file'

删除where子句以查看所有设置，这些设置也可以显示，因为它显示数据目录（pg_hba.conf等）的位置。

Answer 15

除了直接的答案 ，你可能会想看看有关Postgresconfiguration文件位置的文档 。

在大多数情况下：在$PGDATA ，通常是/var/lib/postgresql/data或类似的东西（至less它是默认path，如果你使用Docker镜像的话 ）。
