How to Install Drupal in ubuntu ?

>First we get drupal package :- 
We need to obtain our copy of Drupal so type in
“sudo wget http://ftp.drupal.org/files/projects/drupal-6.13.tar.gz”
this will download the Drupal file into your current directory.

> We need to unpack the files issue the command
“tar –zxvf drupal-6.13.tar.gz”
this will extract the files into a folder in your home directory

>We need to make a directory in the web root folder to keep the Drupal files in. To  do this type in
“sudo mkdir /var/www/drupal”

>We need to move the Drupal content over to the web folder. Type in
“sudo mv drupal-6.13/* drupal-6.13/.htaccess /var/www/drupal”

>We need to set up folders for media associated with the site to do this issue “sudo mkdir /var/www/drupal/sites/default/files”
then
“sudo chown www-data:www-data /var/www/drupal/sites/default/files

>We need to copy and set the Drupal initial config file. To do this we first set copy the settings file by issuing
“sudo cp /var/www/drupal/sites/default/default.settings.php /var/www/drupal/sites/default/settings.php”

then we need to make sure this file is accessible by issuing the command

“sudo chown www-data:www-data /var/www/drupal/sites/default/settings.php”

>NEXT  we install the following packages:-

apache2 ,php5-mysql, php5-gd ,libapache2-mod-php5 ,mysql-server

Using command on terminal " sudo apt-get install apache2 " similarly other packages

> Then Next we need to make sure there is a database in MySQL that Drupal can use.

Where drupal is the name you picked for the mysql database that Drupal will use. You can call it anything you want.

mysql -u root -p

mysql > create database drupal;

mysql> GRANT SELECT, INSERT, UPDATE, DELETE, CREATE, DROP, INDEX, ALTER, 

CREATE TEMPORARY TABLES, LOCK TABLES ON drupal.* TO 'drupaluser'@'localhost'

IDENTIFIED BY 'drupalpass';

mysql> FLUSH PRIVILEGES;

Quit the mysql prompt:  

myspl> \q 

> Now we need to restart Apache to make sure the settings take effect.

 Type in “sudo /etc/init.d/apache2 restart”

Final Installation Settings

>open browser and type http://localhost/drupal/ or http://localhost/drupal/index.php
