Hello everyone! We have been using nginx for a few months now to handle our image serving and processing. Let me run down the basic flow before getting into my config and issues.

A request comes in, we have nginx check to see if the image exists. If it does, we serve it from the filesystem (nice beefy server with a dozen drives in a raid array). If the image doesn't exist, we send the request off to one of a dozen or so upstream servers running php-fpm. They handle the resize, save the image to the filesystem, then nginx serves it. We would like to add one more layer to everything and set these images in memcached so we can serve subsequent requests from memory instead of the filesystem.

Now, the issue is simply adding memcached to our existing config. I come from a long background of apache, so nginx config still kills me sometimes. I figure a visual is the easiest here, so the following is our existing config. If someone could take a look and offer some suggestions, I would really appreciate it.


server {
listen 8080;
server_name localhost;
access_log /var/log/nginx/localhost.access.log;
root /home/images;
index /image.php;




location / {
if (!-f $request_filename) {
rewrite ^(.*)$ /image.php?src=$1 last;
break;
}
}

location ~ "\.(gif|jpeg|jpg|png)$" {
if (!-f $request_filename) {
rewrite ^(.*)$ /image.php?src=$1 last;
break;
}

access_log off;
expires 30d;
}

location ~ "\.(php|phtml)$" {
fastcgi_pass php;
fastcgi_index /image.php;
fastcgi_param SCRIPT_FILENAME /home/images$fastcgi_script_name;
include fastcgi_params;
fastcgi_param QUERY_STRING $query_string;
fastcgi_param REQUEST_METHOD $request_method;
fastcgi_param CONTENT_TYPE $content_type;
