Ispconfig3 on centos5.4 i386 problems

[zenny]

I installed ispconfig3 as stated in http://howtoforge.net/perfect-server...64-ispconfig-3 but have chosen the i386 rpmbuilds. It was working all well till I installed Ispconfig. The squirrelmail and phpmyadmin showed up at IP (not hostname, server1.mydomain.com), but ISPCONFIG panel refuse to show up at myip:8080 port:-( Just getting a blank page trying to load for hours :-(

When I executed php -q install.php to install ISPCONFIG3, I encountered the following errors without me allowing to access the webpanel :-(:

1)
...
Shutting down postfix: [FAILED]

...
httpd: apr_sockaddr_info_get() failed for HOSTNAME=server1.mydomain.net

2) I could not execute the following command with the following error:

#mysqladmin -u root -h server1.mydomain.net password 123456789
mysqladmin: connect to server at 'server1.mydomain.net' failed
error: 'Access denied for user 'root'@'localhost' (using password: NO)'

3) I could not figure out what are the files and in which directory (normally /var/www/html) the sites are hosted? Appreciate if I can get a directory map of what goes where (including config files) after ISPConfig3 installation.

Thanks!!
