Installing Drupal

Hi

I have this error on my page:

warning: mysql_affected_rows(): A link to the server could not be established in /home/cogdziek/public_html/katalog-sklepow/includes/database.mysql.inc on line 222.

Anyone know how to fix it?

browsing to my drupal site, I get:

Access denied for user 'starmonkey'@'localhost' (using password: NO)

despite having, in my default (and only) site's settings.php:

$db_url = 'mysql://starmonkey:mypassword@localhost/starmonkey-tmo-drupal';

and (from my prodn box's shell)

I like to enable forum module. But in Administrator section(modules) there is no module like"Forum" to be activated....

Is forum a contributed module to downloaded and patched or Built in feature of drupal....

Let me know , how do i install and activate forum module

I have installed drupal at http://all4democracy.f2o.org/cms and it worked fine for a few days. But when I tried to access the site after a few days it gave me blank page. So far I did the following:

1) Checked mysql dbs using phpmyadmin, all intact including that of the modules
2) Checked sites/default/settings.php, which is intact
3) Checked the files using gFTP and all were found intact.
4) Renamed .htaccess in the installation root, but the problem persists.

Help solicited!

Problem with mysql. When connecting I receive the following message:

Warning: mysql_connect(): Can't connect to local MySQL server through socket '/tmp' (111) in /home/drupal/includes/database.mysql.inc on line 35
Can't connect to local MySQL server through socket '/tmp' (111)

The socket defined (in /etc/my.cnf) as /tmp/mysql.sock !!! not /tmp!!!

Parsing of db url is ok.
I putted the following lines in database.mysql.inc and got right results.

Trying to start it after installing. Fixed several errors by deleting excess carriage returns, but now I get a new type:

Fatal error: Duplicate entry '4623449ec000c73a56bc8f323b911aa4' for key 1 query: INSERT INTO sessions (sid, uid, hostname, timestamp) VALUES ('4623449ec000c73a56bc8f323b911aa4', 0, '198.69.251.61', 1116117383) in /home2/zoriginm/public_html/pm/drupal-4.6.0/includes/database.mysql.inc on line 66
