Nginx + FastCGI cache

WordPress Nginx
#1

Hello Rahul & crew,

this is not a WP-Nginx related topic, but since you are so highly knowledgeable in the Nginx area, I was hoping you could shed some light on an issue I'm having.

I have been testing the following Nginx FastCGI cache config for Magento. Everything seems to be working just fine. The only problem is that, no matter what rewrite rule I use, Nginx is not parsing the index.php file (always prompting me to download it).

I'm definitely missing something. Probably here:

## Forward paths like /js/index.php/x.js to relevant handler (correct/needed?)  
location ~ .php/ { rewrite ^(.*.php)/ $1 last; }

or here:

## Catch 404s that try_files miss (correct/needed?)  
if (!-e $request_filename) { rewrite / /index.php last; }

Here's my virtual host config (non-relevant parts omitted):

location /index {  
try_files $uri @fcgi_nocache;  
}  

location /checkout {  
try_files $uri @fcgi_nocache;  
}  

location / {  
try_files $uri @fcgi_cache;  
if ($cookie_frontend) { return 413; }  
if ($cookie_CUSTOMER_AUTH) { return 413; }  
if ($request_method = POST ) { return 413; }  
error_page 413 = @fcgi_nocache;  
}  

## Forward paths like /js/index.php/x.js to relevant handler (correct/needed?)  
location ~ .php/ { rewrite ^(.*.php)/ $1 last; }  

location @fcgi_cache {  
## Catch 404s that try_files miss (correct/needed?)  
if (!-e $request_filename) { rewrite / /index.php last; }  
fastcgi_pass unix:/var/spool/phpfpm.sock;  
include fastcgi_params;  
fastcgi_param SCRIPT_FILENAME $document_root/index.php;  
fastcgi_param SCRIPT_NAME /index.php;  

fastcgi_cache APP;  
fastcgi_cache_key "$scheme$request_method$host$request_uri$http_if_modified_since$http_if_none_match";  
fastcgi_cache_valid 200 301 302 304 1h;  
fastcgi_hide_header "Set-Cookie";  

if ($http_cookie !~ "X-Store=1" ) { add_header Set-Cookie "X-Store=1; path=/"; }  

fastcgi_ignore_headers "Cache-Control" "Expires" "Set-Cookie";  
fastcgi_cache_min_uses 1;  
fastcgi_cache_valid 30m;  
fastcgi_cache_use_stale updating error timeout invalid_header http_500;  
fastcgi_cache_bypass $cookie_EXTERNAL_NO_CACHE $cookie_CUSTOMER_AUTH;  
fastcgi_no_cache $cookie_EXTERNAL_NO_CACHE $cookie_CUSTOMER_AUTH;  

add_header X-Nginx-Cache $upstream_cache_status;  
}  

location @fcgi_nocache {  
## Catch 404s that try_files miss (correct/needed?)  
if (!-e $request_filename) { rewrite / /index.php last; }  
fastcgi_pass unix:/var/spool/phpfpm.sock;  
include fastcgi_params;  
fastcgi_param SCRIPT_FILENAME $document_root/index.php;  
fastcgi_param SCRIPT_NAME /index.php;  

if ($http_cookie !~ "X-Store=1" ) { add_header Set-Cookie "X-Store=1; path=/"; }  
}

Any help is more than welcome!

Thanks and keep up the great work!

Try adding a PHP-handler block:

location ~ \.php$ {  
    try_files $uri /index.php ;   
    fastcgi_pass unix:/var/spool/phpfpm.sock;  
    include fastcgi_params;  
    #other rules...   
}

I am not sure about this line as I never worked on Magento:

location ~ .php/ { rewrite ^(.*.php)/ $1 last; }
