Обсуждение: Help in connecting to a database with PHP
Hi:
I’m trying to learn how to set up a .php file to connect to my PostgreSQL database. From the command line, I can connect, open and work in the database on my machine. However, if I create a .php page with the following information:
$db = pg_connect(“dbname=baseball user=postgres”);
I get the following error message:
Warning: Unable to connect to PostgreSQL server: FATAL 1: IDENT authentication failed for user “postgres” in /var/www/html/baseball.php on line 10.
I’m running a stock Red Hat Linux 7.3 machine with PostgreSQL version 7.2. I have verified that from the command line, I can switch to the user postgres and connect to the database with no problems. I can view data, add and delete records, etc.
I’d appreciate some help in trying to track down what I’m doing wrong. I’ve spent the past few days looking at documentation from various web sites, and nothing seems to jump out as the culprit.

Try checking the file "pg_hba.conf" ( Usually in
/usr/local/pgsql/data). It seems that your connection
requires a password. try to set the "auth_type" to
"trust" in "pg_hba.conf" to skip password check or use
"pg_connect(dbname=baseball user=postgres
password=<password of the user account "postgres");"
Hope that helps.
ludwig.

If you are accessing the database via a web server, you should allow
TCP/IP connections. (postmaster -i)

This looks like a socket connection, not TCP/IP.
