Обсуждение: Error connecting database

I'm just trying to run PGSQL and running the test for it. However I get this
message,

Connection to database 'template1' failed.
connectDB() -- connect() failed: No such file or directory
Is the postmaster running at 'localhost' and accepting connections on Unix
socket '5432'?

createdb: database creation failed on i-city.

What does that mean? Is it mean that the connect() file is not found under
my /usr/local/pgsql/bin?

You don't give many details.  I'll assume you're using some variant of
Unix.

[1] Have you checked that the postmaster is running?  Try running 'ps
aux' to check that it is.

[2] Have services been enabled for port 5432?  Check /etc/services.
I have a pair of lines:
    postgres        5432/tcp                        # POSTGRES
    postgres        5432/udp                        # POSTGRES

[3] Do you have permissions to the given database?

[4] When all else fails, you can try running strace on the process.
(Please read the strace man page).

Hope this helps!

You might want to check that you have run initdb.  Log in as user postgres
and type:

  /usr/local/pgsql/bin/initdb

Then check to make sure that postmaster is actually running, as someone
else suggested.

Also, you might want to check whether you have started the server with
the "-i" option (that's what the Unix Socket message suggests).
