Question

brew install postgresql

...初始化

[~] initdb   
The files belonging to this database system will be owned by user "pma".
This user must also own the server process.

The database cluster will be initialized with locales
  COLLATE:  C
  CTYPE:    UTF-8
  MESSAGES: C
  MONETARY: C
  NUMERIC:  C
  TIME:     C
The default database encoding has accordingly been set to UTF8.
initdb: could not find suitable text search configuration for locale UTF-8
The default text search configuration will be set to "simple".

WARNING: enabling "trust" authentication for local connections
You can change this by editing pg_hba.conf or using the -A option the
next time you run initdb.

Success. You can now start the database server using:

    postgres -D /Users/pma/.pgdata
or
    pg_ctl -D /Users/pma/.pgdata -l logfile start

...开始

[~] pg_ctl start
server starting
[~] LOG:  database system was shut down at 2011-11-30 22:41:57 HKT
LOG:  database system is ready to accept connections
LOG:  autovacuum launcher started

到目前为止一切都那么好...... Createdb ....

[~] createdb test 
createdb: could not connect to database postgres: could not connect to server: Permission denied
    Is the server running locally and accepting
    connections on Unix domain socket "/var/pgsql_socket/.s.PGSQL.5432"?

......现在是什么？

Answer 1

可能是unixdomain套接字位于其他位置，例如/ tmp

尝试将-h标志与localhost或/ tmp：

一起使用

createdb -h localhost test，或
createdb -h / tmp test

（ - h / --hostname标志通常将主机名作为参数，但它也会接受一个目录名，指定unix-domain套接字的位置）

Answer 2

请注意2015年6月在山狮上安装brew的postgres：plsq和createdb正在/ var / pgsql_socket中查找套接字，但postgres正在/ tmp中创建它。 “plsq -h localhost”工作正常，但要永久修复：

sudo mkdir /var/pgsql_socket sudo chown <user> /var/pgsql_socket

然后编辑/usr/local/var/postgres/postgresql.conf，并设置 unix_socket_directories ='/ var / pgsql_socket'

Answer 3

您是否拥有用户创建数据库的权限？如果不是，您可以通过以下方式创建/更改用户：

创建用户

> su postgres
> createuser
    ... Set user permission.

另请检查您的pg_hba.conf您是否拥有适合您用户的权限。

无法让Postgres开始
