codeigniter .htaccess in amazon ec2 removal of index.php not working

You can change your .htaccess like this

RewriteEngine onRewriteCond %{REQUEST_FILENAME} !-fRewriteCond %{REQUEST_FILENAME} !-dRewriteRule .* index.php/$0 [PT,L]

and change the value of "AllowOverride None" on /etc/httpd/conf/httpd.conf (if you use AMI Linux)

into "AllowOverride All"

after that restart your apache with command like this:

sudo service httpd restart

It's work and tested on my aws ec2.

(if you use ubuntu)Activate the mod_rewrite module with     sudo a2enmod rewriteand restart the apache     sudo service apache2 restartTo use mod_rewrite from within .htaccess files (which is a very common use case), edit the default VirtualHost with     sudo nano /etc/apache2/sites-available/000-default.confSearch for “DocumentRoot /var/www/html” and add the following lines directly below:    <Directory "/var/www/html">        AllowOverride All    </Directory>Save and exit the nano editor via CTRL-X, “y” and ENTER.Restart the server again:     sudo service apache2 restart

Justudin is correct!

Also you can use the "AllowOverride All" rule to only your project; writing in /etc/httpd/conf/httpd.conf something like this:

<Directory "/var/www/your_website">    AllowOverride All</Directory>
