Обсуждение: psql: FATAL: missing or erroneous pg_hba.conf file

Hi All,

new here, and pgsql in general. I currently use MySQL and now need to know pgsql. I have set it up on my Linux box, CentOS 4-3, using an RPM from Dag Wieer's repos. I am getting the following,

[racket@ibmlap lib]$ psql template1
psql: FATAL:  missing or erroneous pg_hba.conf file
HINT:  See server log for details.


after following here,

http://polder-linux.org/modules.php?name=News&file=article&sid=182

as I was eperiencing the same problem as the user at the bottom,

Warning: pg_connect() unable to connect to PostgreSQL server: FATAL 1: IDENT authentication failed for user "arjen"

Refer to PostgreSQL Administrator's guide, Chapter 4: Client Authentication.

You probably have this line in the /var/lib/pgsql/data/pg_hba.conf:

local all ident sameuser

(I know RedHat 8.0 does this). You need to change this into:

local all trust

This tells PostgreSQL to allow any UNIX user to log into the database as any database user on a local socket.

and here,

http://serghei.net/docs/database/pgresql-7.1-admin/client-authentication.html


I'm a little lost. Could someone steer me in the right direction? Cheers.

Mark Sargent.

Mark,

and what exactly is there in server log?

Reading your words I assume you made a typing error while editing pg_hba.conf

No typo. Thought I'd pasted this in the first post. Sorry about that.

# TYPE  DATABASE    USER        CIDR-ADDRESS          METHOD

# "local" is for Unix domain socket connections only
local   all         trust
# IPv4 local connections:
host    all         all         127.0.0.1/32          ident sameuser
# IPv6 local connections:
host    all         all         ::1/128               ident sameuser

Cheers.

That's short one "all": you need type, database, user, method columns
(but no address column for "local").

Hi All,

yes, Tom, you're correct. Someone mailed me directly(thank you), with a
link to their site's tut on authentication, and I picked up on it
straight away. Seems the sites I was looking at were wrong. Anyway, I
now get this,

[racket@ibmlap ~]$ psql template1
psql: FATAL:  role "racket" does not exist

Log output:
LOG:  database system is ready
LOG:  transaction ID wrap limit is 2147484146, limited by database
"postgres"
FATAL:  role "racket" does not exist

Which confuses me, as local all all trust should allow me to connect,
no? Or, is there a particular syntax when connecting locally? I can't
imagie that being so, but then agan, I would have expected this to be a
little easier than it has been already. Cheers.

No, it allows you to claim that you are any database user you want to
claim you are.  The default assumption is that you want to be the
database user with the same name as your OS username.  The problem here
is that there is no such user.

Most likely the only pre-existing database user will be named
"postgres", so try

    psql -U postgres template1

If that lets you in, execute the SQL command "CREATE USER racket;"
and then you should be able to connect as "yourself".  (Note: you might
prefer to make yourself a superuser, see the manual.)
