How to remove index.php from URL

[eluser]ebrahimthex[/eluser]
How can i remove index.php in my LAMP Server.

This works: http://localhost/mysite.com/index.php/home
But this generates 404 errors: http://localhost/mysite.com/home

Code:

<VirtualHost *:80>
ServerAdmin webmaster@localhost

DocumentRoot /var/www
<Directory />
  Options +FollowSymLinks
  AllowOverride None
</Directory>
<Directory /var/www/>
  Options Indexes +FollowSymLinks MultiViews
  AllowOverride None
  Order allow,deny
  allow from all
</Directory>

ScriptAlias /cgi-bin/ /usr/lib/cgi-bin/
<Directory "/usr/lib/cgi-bin">
  AllowOverride None
  Options +ExecCGI -MultiViews +SymLinksIfOwnerMatch
  Order allow,deny
  Allow from all
</Directory>

ErrorLog ${APACHE_LOG_DIR}/error.log

# Possible values include: debug, info, notice, warn, error, crit,
# alert, emerg.
LogLevel warn

CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>

and this is my .htaccess in /var/www/russelhost/

Code:

RewriteEngine on
RewriteBase /russelhost/
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php/$1 [L]

and I also Change from application/config/config.php

Code:

$config['index_page'] = “index.php” by $config['index_page'] = “”
$config['uri_protocol'] = “AUTO” by $config['uri_protocol'] = “REQUEST_URI”

Now What Can i do?
