问题
Installed LAMP stack. Right now I've extracted codeigniter files to /var/www/ci but while running on browser http://localhost/ci/ the welcome page doesn't display.

Finally found the answer. Have to enable the site.
In /etc/apache2/sites-available/000-default.conf file shud modified as follows:
<VirtualHost *:80>
DocumentRoot /var/www/
ServerAdmin webmaster@localhost
<Directory /var/www/ci/>
AllowOverride All
</Directory>
ErrorLog ${APACHE_LOG_DIR}/error.log
CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>
And this worked for me! Thanks all.

If you are using ubuntu 14.04 the web server inside var/www/html, so move your folder into var/www/html/ci.
And open .htaccess file inside ci folder.paste the following code
<IfModule mod_rewrite.c>
RewriteEngine on
RewriteBase /ci/
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php/$1 [L]
</IfModule>

You can set the base url in /application/config/config.php on line 26.
$config['base_url'] = 'http://localhost/ci/';
If that doesn't solve the problem you have to post more informations.
Fresh codeigniter install?
No third party plugins?
No changes to routes? (in /application/config/routes.php)
No changes to the controller?
No changes to the view?
Do you get errors?
If not check if error reporting is on in the index.php (set it hard to development for testing)
Do you use Rewrite rules in an .htaccess in the /var/www/ci/ folder?
Do you autoload anything? libraries, models, languages, helpers ?
If you can't find anything, set this to 4:
$config['log_threshold'] = 4;
in /application/config/config.php on line 216.
The log file is written to /application/logs/.
Post that log, probably it helps.
