Installing Drupal

I want to create multiple sites, I did this steps.

Step 1. Install Drupal at domain1.com.
Step 2. Create a new MySQL database and user for domain2.com.
Step 3. Create a directory in /sites/domain2.com/.
Step 4. Copy /sites/default/default.settings.php to /sites/domain2.com/
Step 5. Rename /sites/domain2.com/default.settings.php to /sites/domain2.com/settings.php, set the domain2.com database parameters in settings.php.

What permissions must be on sites, sites/default, sites/default/files, sites/default/settings,php, sites/default/default.settings,php. Before i start install i change it on 777, but now i can't remember what permissions was before. I read install.txt, there write only for sites/default/files and sites/default/settings,php.
Now after installation i have:
sites directory - 777
sites/default - 774
sites/default/files - 777
sites/default/settings,php - 644
sites/default/default.settings,php - 644

I am using XAMMP on a Win2003 server. To get the Apache server to run I had to change the listening port from 80 to 8080 and the SSL port from 443 to 4499.

I used phpmysql to create a database on the MySQL server (Drupal) and created users with privileges for the drupal database. One user has "any database" privileges and another I specifically specefied "/localhost:8080"

Hi I am setting up a blog related to seo (προώθηση ιστοσελίδων) and I was wondering which one to choose!Which one is better for seo purposes? Thanks In advance.

Hi,

I migrate my Drupal 7 site from web hosting A to hosting B.

Under Hosting A, I used following SSH to backup folders and files:
tar --create --gzip --verbose --file=files_backup.tgz site_foldername

and used following SSH to backup database:
mysqldump -uhosta_admin -ppassworda --add-drop-database hosta_databasename > database_backup.sql

---------------------------
So, I have two files of the whole website backup:
files_backup.tgz
database_backup.sql

-----------------------------
On the web hosting b, I create an empty database (hostb_databasename) with user hostb_admin

I used following SSH to restore database:
mysql -uhostb_admin -ppasswordb hostb_databasename < database_backup.sql

and used following SSH to restore folders and files:
tar -xvzf files_backup.tgz

-------------------------
Next step, I updated the sites/defaule/settings.php file with the database, username and possword associated with web hosting b.

------------------------

I assume everything would be fine, but when I open website, I got following error:

Error

The website encountered an unexpected error. Please try again later.

PDOException: SQLSTATE[28000] [1045] Access denied for user 'hostb_admin'@'localhost' (using password: YES) in lock_may_be_available() (line 167 of /home5/******/public_html/includes/lock.inc).

----------------------

I had an instance of drupal7 running fine themed and ready to go everything setup. I then updated my domain name and changed the dns to point to my server and then added the domain to my account and had it point to the folder with drupal already setup. The site worked fine (I went to it and logged in as admin) for a moment except for some images so I hit clear all caches. Hoping to fix the problem. Now I get the white screen of death (WSOD). I can't access the admin or anything.
