Installation Drupal 7

Installing and running Drush

Drush was easily installed with apt-get install drush. On the web root directory (e.g. /home/www-data) I issued the following command:

drush dl drupal-<version>  - in my case drush dl drupal-7.10

Multisite Setup

For the multisite setup I followed this guide (http://drupal.org/node/53705)

No default installation - the main .com site was created under /sites/xyz.com

Creation of drupal user in mysql

I created the database in mysql according to the information on the drupal website (http://drupal.org/documentation/install/create-database)

 For information on installing and configuring MySQL see http://dev.mysql.com/tech-resources/articles/mysql_intro.html

In the following examples, 'username' is an example MySQL user who will have the CREATE and GRANT privileges and 'databasename' is the name of the new database Use the appropriate names for your system.

Create a new database for your site.
mysqladmin -u username -p create databasename

MySQL prompts for the 'username' database password, and creates the initial database files.

Log in and set the access database rights:
mysql -u username -p

MySQL prompts for the 'username' database password.

At the MySQL prompt, set the permissions using the following command:
GRANT SELECT, INSERT, UPDATE, DELETE, CREATE, DROP, INDEX, ALTER, LOCK TABLES, CREATE TEMPORARY TABLES ON `databasename`.* TO 'username'@'localhost' IDENTIFIED BY 'password';

In this case:

'databasename' is the name of your database
'username@localhost' is the username of your MySQL account
'password' is the password required for that username
You will need the ` around the database name if you have used a MySQL escape character in your schema name.

Eg: drupal_test_account.* should be drupal\_test\_account.* for security (underscore is a wildcard). This requires the ` wrapper. `drupal\_test\_account`.*

Note: unless your database user has all of the privileges listed above, you will not be able to run Drupal.

If successful, MySQL will reply with:
Query OK, 0 rows affected

To activate the new permissions, enter the following command:
FLUSH PRIVILEGES;

The database should be created with UTF-8 (Unicode) encoding.

Now exit the MYSQL prompt by typing:
exit
The server will answer by saying
Bye

Installation Script

After that I just normally ran the installation script (http://drupal.org/documentation/install/run-script),

entered a some informaton about database name, passwords, admin etc.After that Drupal was up and running
