问题
I'm setting up my local postgresql database for a rails project (that I'm joining), and have done the following:
- Installed postgres
- Added/bundled 'pg' gem
- Created a db user named "foobar"
- Created a db named "foobar_development"
The rails app comes with a rake db:migrate task. When I run this task, I get the following error output:
FATAL: no pg_hba.conf entry for host "::1", user "foobar", database "foobar_development", SSL off
I found a pg_hba.conf file in the following location:
/usr/local/var/postgres
Here's the relevant part of the pg_hba.conf file:
# TYPE DATABASE USER ADDRESS METHOD
# "local" is for Unix domain socket connections only
local all all trust
# IPv4 local connections:
host all all 127.0.0.1/32 trust
# IPv6 local connections:
host all all ::1/128 trust
# Allow replication connections from localhost, by a user with the
# replication privilege.
#local replication jimmyli trust
#host replication jimmyli 127.0.0.1/32 trust
#host replication jimmyli ::1/128 trust
I am using the postgres that came with my Mac (version 9.2.4), although I'm worried I might have installed another version of it somewhere else (and ought to remove it - anyway I can check this?). I am also using Postgres.app to run psql. (http://postgresapp.com/).
I think my pg_hba.conf file ought to work correctly (since I'm giving all users access to all dbs), so I wonder if there's another pg_hba.conf file out there, and that I'm looking at the wrong one/one that's not being used. How can I test this hypothesis?
回答1:
Got it! Looks like I was looking at the wrong/irrelevant pg_hba.conf file. To find the right one, I logged into the db with psql and ran "SHOW hba_file"
This gave me the path to the relevant file, which in my case was:
/Library/PostgreSQL/9.1/data
I then added the right lines (see my question) to this question, and everything worked!.
回答2:
Did you reload postgresql after making the change to your pg_hba.conf file? Try logging into the db as a superuser and issue select pg_reload_conf(); to reload the pg_hba.conf and postgresql.conf files.
回答3:
pg_hba.conf is supposed to be copied to your data directory. According to the list here, it should be in ~/Library/Application\ Support/Postgres/var. Hope that helps...
回答4:
Set the following environment variable in command line to require SSL for Postgres connections:
$ export PGSSLMODE=require
