Обсуждение: createdb: could not connect to database

Dear All

I have just installed postgres 8.1.2 on a computer running Fedora Core
4 with the rpms got from postgres site. However, I get the following:


$ createdb mydb
createdb: could not connect to database postgres: could not connect to
server: No such file or directory
        Is the server running locally and accepting
        connections on Unix domain socket "/tmp/.s.PGSQL.5432"?
$

Any idea about how to overcome the problem?

Thanks in advance,

Paul

Did you start postgresql service?

# service postgresql start

Thanks, Devrim. After "service postgresql start", I get

$ createdb mydb
createdb: could not connect to database postgres: FATAL:  role
"psmith" does not exist
$

- By default, RPM installations use ident authentication. This basically
means that you must be postgres user to access to PostgreSQL. First su
to root, and the su to postgres and run createdb then. (you cannot
directly su to postgres since it does not have an initial password)

- You can also edit pg_hba.conf to allow access to regular users:
http://www.postgresql.org/docs/8.1/static/client-
authentication.html#AUTH-PG-HBA-CONF

- You can create psmith role and allow access to that user.

Create a database user:
Become root with su, then 'su - postgres', then createuser.

Read & edit the file 'pg_hba.conf'
