Hi,

I've had to rebuild our web server and now my php scripts will not connect
to postgres can anyone tell me why?

Thanks for any help, details below.
Annie

I was using Redhat9, postgres 7.3.4, php 4.2.2 and apache2
now using Fedora core 4, postgres 8.0.3, php 5.0.4 and apache2

I know php is configured for psql
http://zeldia.cap.ed.ac.uk/Lumbribase/php_info.php

In postgrsql.conf I tried changing listen_addresses = 'localhost' to
listen_addresses = '*' but that didn't work.

I think the pg_hba.conf is OK..
# "local" is for Unix domain socket connections only
local all all ident sameuser
# IPv4 local connections:
host all all ***.*.*.*/** ident sameuser
# IPv6 local connections:
host all all ::*/*** ident sameuser

The error in /var/log/http/error_log is...
[client ***.***.***.***] PHP Warning: pg_connect() [<a
href='function.pg-connect'>function.pg-connect</a>]: Unable to connect to
PostgreSQL server: FATAL: Ident authentication failed for user
"webuser" in /var/www/html/Lumbribase/pg_name.php on line 17,
referer: http://zeldia.cap.ed.ac.uk/Lumbribase/search_id.php

and a typical php connection script is...
$PG_HOST="localhost";
$PG_PORT=5432;
$PG_DATABASE="lumbribase";
$PG_USER="webuser";
$PG_PASS="";
$PI=pi();

$dbconn=pg_connect( "dbname=$PG_DATABASE host=$PG_HOST port=$PG_PORT
user=$PG_USER password=$PG_PASS" );
if ( ! $dbconn ) {
echo "Error connecting to the database !<br> " ;
printf("%s", pg_errormessage( $dbconn ) );
exit();
}

TIP 6: explain analyze is your friend

Hi, John!

Note that the above configuration will use 'ident sameuser'
authentication for connections via tcp/ip (like the one you're trying
from your webserver). So, your connection will need an OS account
(and no password supplied). That's what your error_log is telling you,
and I'm guessing that the account you're supplying for the connection
is not an OS account, but a Postgres account. If you want to use
Postgres account authentication (e.g. users created via CREATE USER in
Postgres DB), perhaps you should try md5 authentication in your
pg_hba.conf.
