apache mod-rewrite to nginx rewrite

Question

I just changed to NGINX from Apache and I am using Zencart with Ultimate SEO for friendly urls I have tried to convert my .htaccess rules for NGINX but I get "No Input file specified" or a 404 error. My original .htaccess is as follows:

 ErrorDocument 404 /404.html


 Options +FollowSymLinks
 RewriteEngine On




 # From Ultimate SEO URLs
 RewriteRule ^(.*)-p-(.*).html$ index\.php?main_page=product_info&products_id=$2&%{QUERY_STRING} [L]
 RewriteRule ^(.*)-c-(.*).html$ index\.php?main_page=index&cPath=$2&%{QUERY_STRING} [L]
 RewriteRule ^(.*)-m-([0-9]+).html$ index\.php?main_page=index&manufacturers_id=$2&%{QUERY_STRING} [L]
 RewriteRule ^(.*)-pi-([0-9]+).html$ index\.php?main_page=popup_image&pID=$2&%{QUERY_STRING} [L]
 RewriteRule ^(.*)-pr-([0-9]+).html$ index\.php?main_page=product_reviews&products_id=$2&%{QUERY_STRING} [L]
 RewriteRule ^(.*)-pri-([0-9]+).html$ index\.php?main_page=product_reviews_info&products_id=$2&%{QUERY_STRING} [L]
 RewriteRule ^(.*)-ezp-([0-9]+).html$ index\.php?main_page=page&id=$2&%{QUERY_STRING} [L]



 # All other pages
 # Don't rewrite real files or directories
 RewriteCond %{REQUEST_FILENAME} !-f [NC] 
 RewriteCond %{REQUEST_FILENAME} !-d
 RewriteRule ^(.*).html$ index\.php?main_page=$1&%{QUERY_STRING} [L]

And this us what I have added in to the virtual.conf in NGINX

 rewrite ^/(.*)-p-(.*).html$ /index\.php?main_page=product_info&products_id=$2&$args last;
 rewrite ^/(.*)-c-(.*).html$ /index\.php?main_page=index&cPath=$2&$args last;
 rewrite ^/(.*)-m-([0-9]+).html$ /index\.php?main_page=index&manufacturers_id=$2&$args last;
 rewrite ^/(.*)-pi-([0-9]+).html$ /index\.php?main_page=popup_image&pID=$2&$args last;
 rewrite ^/(.*)-pr-([0-9]+).html$ /index\.php?main_page=product_reviews&products_id=$2&$args last;
 rewrite ^/(.*)-pri-([0-9]+).html$ /index\.php?main_page=product_reviews_info&products_id=$2&$args last;
 rewrite ^/(.*)-ezp-([0-9]+).html$ /index\.php?main_page=page&id=$2&$args last;
 if (!-f $request_filename){
 set $rule_7 1$rule_7;
}
if (!-d $request_filename){
set $rule_7 2$rule_7;
}
if ($rule_7 = "21"){
rewrite ^/(.*).html$ /index\.php?main_page=$1&$args last;
}

    }

Any ideas what I have done wrong?

Answer 1

Without the whole server definition it's hard to tell what's happening because location directives are processed in a specific order and your php configuration may be causing an issue.

Anyway, the most obvious problem is in the index.php rewrites. Don't slash escape the period. (index\.php should be index.php).

As for the last part, it can be simplified:

if (-f $request_filename) {
  break;
}
if (!-d $request_filename) {
  rewrite ^/(.*).html$ /index.php?main_page=$1&$args last;
}

Answer 2

Well, you can start by replacing those hideous compound if statements with try_files:

try_files $uri $uri/ /index.php?main_page=$uri&$args;

Removing the escapes on the periods in the replacement part of the rewrite directives wouldn't hurt, either; I don't know if nginx handles them as you expect, but they're certainly not doing you any good.

Apart from that, nothing looks particularly out of place, so fix up those things and check your error log; 404s log what they failed to find so you can see what you've done wrong.
