Rewrite code from htaccess to nginx config?

Question

I have problem with implement my rewrite code from htaccess file into nginx config. I've already tried generator : http://winginx.com/htaccess for generate my rewrite code.

My nginx config code:

server {
        listen 80;
        server_name example.com;
        return 301 $scheme://www.example.com$request_uri;       
}

server {
        listen 80;
        root /usr/share/nginx/www;
        index index.php;
        server_name www.example.com;
        error_page 404 http://www.example.com/404.php;
        autoindex off;
        error_log  /usr/share/nginx/www/nginx_error.log  warn;

   location / {
        rewrite ^([^\.]*)$ /$1.php;
    }

    location = / {
        rewrite ^ /index.php;
    }

    location ~ \.php$ {
        include fastcgi_params;
        fastcgi_pass unix:/var/run/php5-fpm.sock;
    }

}

I wanna implement this from my .htaccess:

RewriteRule ^([A-Za-z0-9-]+)/([A-Za-z0-9-/_]+)$ admin/index.php?hotelname=$1&do=$2 [QSA]
RewriteRule ^(([A-Za-z0-9-/]+)+)$ admin/index.php?hotelname=$1 [L]

Generated code from tool:

location / {
  rewrite ^/([A-Za-z0-9-]+)/([A-Za-z0-9-/_]+)$ /admin/index.php?hotelname=$1&do=$2;
  rewrite ^/(([A-Za-z0-9-/]+)+)$ /admin/index.php?hotelname=$1 break;
}

I have alredy tried implement this last lines of code to my location blocks but not working at all.. I will be very greateful for every opinion! Regards Makromat

Answer 1

The blind kind of conversion would be

rewrite ^([A-Za-z0-9-]+)/([A-Za-z0-9-/_]+)$ admin/index.php?hotelname=$1&do=$2&$query_string last;
rewrite ^(([A-Za-z0-9-/]+)+)$ admin/index.php?hotelname=$1 last;

But I would prefer if I understand the question more to produce a more optimum rewrite.

When do I know if the URL should be passed to /admin or not, give me an actual URI for backend and for frontend.

Usually rewrites are better managed in nginx using nginx way of thinking. And this new way of thinking is more based on try_file.

So you may try something like that (untested):

location ^~ "/([A-Za-z0-9-]+)/([A-Za-z0-9-/_]+)"  {
    try_files $uri admin/index.php?hotelname=$1&do=$2&$args;
}
location ^~ "(([A-Za-z0-9-/]+)+)" {
    try_files $uri /admin/index.php?hotelname=$1;
}
location = / {
    rewrite ^ /index.php;
}
location ~ \.php$ {
    include fastcgi_params;
    fastcgi_pass unix:/var/run/php5-fpm.sock;
}

If direct access on given $urishould never happen, then remove that part from the try_files. Now I'm also unsure of your second regex (([A-Za-z0-9-/]+)+), why not using:

location ^~ "/([A-Za-z0-9-/])+"

Or

location ^~ "/([A-Za-z0-9-])+/"

So there's maybe something I do not see, even in your apache rewrites.
