Asynchronous Mode - Connection refused

Please see omega8cc's setup for Drupal + Nginx + Advagg!

I have placed a direct link to the file that will help you
with the best setup:

https://github.com/omega8cc/nginx-for-drupal/blob/master/aegir/conf/ngin...

You could be using a older Nginx that does not support "named locations"
- Else, you have a error in the nginx.conf.

I am happily using the same Pressflow + Advagg as you.
Yes, I have [once] been through the same issues as you have reported :-)

The nginx 500 error simply means 'misconfiguration' [something illegal within nginx.conf]

Does it help if I attach my working nginx.conf file for you to study?

I had a quick look at your two config files: [messy code *smile*]
"They both need a clean rewrite"

Why not use one of the above [working examples] to get a clean working nginx config?

Also the named location should be moved to after the caller [ref]!

    ###
    ### advagg_css and advagg_js support
    ###
    location ~* files/advagg_(?:css|js)/ {
	root /var/www/madfanboy.com;
        access_log off;
        expires 365d;
        add_header Pragma "";
        add_header Cache-Control "public";
        try_files $uri @drupal;
    }

# only needed for Drupal 6 (or if you absolutely need a named location)
location @drupal {
rewrite ^ site/index.php?q=$uri last; # for drupal 6
}

If those two files are your total setup for nginx; there is a lot of 'normal' nginx handling missing...
A sound structure is required, I think.

Refer #8:

# only needed for Drupal 6 (or if you absolutely need a named location)
location @drupal {
    rewrite ^ site/index.php?q=$uri last; # for drupal 6
}

The code [above] is not correct for any folder(s), as we *must* use /index.php in the D6 web root.

This code *is* correct, regardless of what folder(s):

location @drupal {
  rewrite ^/(.*)$  /index.php?q=$1 last;
}

The folder locations are handled by index.php (and the 'args' supplied) - assuming it is non-static (php) GET

You may be referring to multi-site domains + folders?

The

"This path is completely wrong:
/usr/local/nginx//html/site/sites/default/files/advagg_css/css_missing6730073131317950516_0.css

results because of your nginx setup (as I read it in the two attached files). You are defaulting to the nginx install / config location - rather than the www location.

Refer: # 16

One more question - above Nginx config will work if I don't have php FastCGI via Nginx?

You will need pickup and deal with the references to 'fastcgi' compared to your current 'PHP proxy bypass' to apache!

The difference is not too much! Basically, your current method is employing the older + traditional nginx proxy bypass to let apache handle the PHP 'grunt work'. With PHP5.3.x, the nginx fastCGI PHP is much preferred [over apache].

proxy_pass http://127.0.0.1:8080;

Think seriously [soon - when you are code ready] to moving everything [via http] over to nginx, and dropping apache.
There are great benefits.
I have been on the same progressive path you are treading this day. It is worth your time to flow with it - step -by- step.
You are not alone, many walk with you :-)

But if ill transfer my apache php to nginx php-fpm it will scrap all my php settings - memcache, apc? Nginx doesn’t work well with .httacces? All Drupal modules work well with this config?

No, all the above PHP modules are OK. Nginx does not need or use .htaccess. You implement your own nginx .htaccess methods, and they are documented [but you will need read a lot].

I see that you must be using a Debian / Fedora / Ubuntu Linux: so just use "apt-get install php5-fpm"

See: http://www.howtoforge.com/installing-php-5.3-nginx-and-php-fpm-on-ubuntu...
and: https://github.com/perusio/drupal-with-nginx [a very skilled nginx supporter]

@superfedya
Fixing this issue here will hopefully fix your other issue here #1138098-31: Pre generation kills the machine. Both modules use the same idea; issue a secondary request to do background processing.

Postponing this issue as I haven't heard anything. If everything is working, go ahead and close this issue.

same here.

My nginx is with in reverse proxy. So localhost connection always will be refused.

reverse_proxy enabled in Drupal.

any help?

Closing out older issues.
