Arun David's questions

Previously i was using linode VPS running Apache for my CodeIgniter website. Today i installed nginx and my website landing page is coming but the other pages that is using htaccess for rewriting URL is not coming. This is my htaccess,

RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ /index.php/$1

What is the nginx equalent for my htaccess? Also is there any changes do I need to make in my codeigniter config and application??..

For URI protocal in codeigniter config, I am using,

$config['uri_protocol'] = 'PATH_INFO';

Will this work with nginx??..

When I tried to install php-gd library in my GoDaddy VPS with CentOS, It gives:

$ yum install php-gd
