Hello, I'm new in this forum and I really need someone help. Please help me :)

This is .htaccess code:

RewriteEngine On

# Uncomment (remove #) line below if installed in folder and add folder name after /
#Rewritebase /

RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f

# Application Handler
RewriteRule ^([_A-Za-z0-9-]+)/?$ index.php?action=$1 [QSA,NC,L]
RewriteRule ^([_A-Za-z0-9-]+)[+]$ index.php?action=stats&id=$1 [QSA,NC,L]

# Admin Panel
RewriteRule ^admin/([_A-Za-z0-9-]+)/?$ admin/index.php?action=$1 [QSA,NC,L]

# Application
RewriteRule ^([_A-Za-z0-9-]+)/([_A-Za-z0-9-]+)/?$ index.php?action=$1&do=$2 [QSA,NC,L]
RewriteRule ^sitemap.xml$ sitemap.php

ErrorDocument 404 /index.php?action=404



I convert it with http://winginx.com/en/htaccess. and result is


# nginx configuration

error_page 404 /index.php?action=404;

location / {
if (!-e $request_filename){
rewrite ^/([_A-Za-z0-9-]+)/?$ /index.php?action=$1 break;
}
rewrite ^/([_A-Za-z0-9-]+)[+]$ /index.php?action=stats&id=$1 break;
rewrite ^/([_A-Za-z0-9-]+)/([_A-Za-z0-9-]+)/?$ /index.php?action=$1&do=$2 break;
}

location /admin {
rewrite ^/admin/([_A-Za-z0-9-]+)/?$ /admin/index.php?action=$1 break;
}

location = /sitemap.xml {
rewrite ^(.*)$ /sitemap.php;
}




But main problem is I can't configure it still now.

This is my /etc/nginx/sites-available/default file. ( I think this is the area where i need to put it)
