EDIT:- was just googling and found a site which say about this issue :-


when nginx is used as a reverse proxy to Apache, the visitors' IPs received by Apache are wrong - all requests to Apache come from nginx, so the main server IP will be logged.
To make Apache log the real IPs of the visitors instead of the main server IP, a special Apache module (mod_rpaf) is needed.


so wasn't it installed at my time or is not installed any time ?

First of all about mod_rpaf - we have been installing it since the beginning. Apache log proper IPs. The only issue with badly written scripts (I wonder why vB such a script!) which blindly use REMOTE_ADDRESS variable to use it as remote IP without looking at extra variables like X_REAL_IP.

Now back to status.php script - if it may quickly send response to Nginx, then it will save your RAM because script will be ready to serve new requests while Nginx serve so-called slow clients. With standalone Apache script stays in RAM during the session.

You may give Nginx a try, if it won't work for you, we will properly uninstall it and refund the payment. Risk free!

ok i got it installed but just for one day , surely it reduced load but too bad that it doesn't support upload progress bar , i have file mirroring site and users are getting confused to see error no upload status , hope this issue gets fixed soon in newer versions of Nginx so i can reinstall it

.htaccess supported ?

[whmphp]

I would like to also ask , do we need to update ngnix config file each time when we add a domain using whm ?

Or you will edit cpanel's account creation script and add codes for automatic update ? In that case, what if cpanel updates itself ?

[whmphp]

Also, can I install it on LxAdmin using Apache ?

[ispro]

We updated our internal scripts to Nginx 0.8.5 with custom patchset. Contact us if you'd like to schedule install. There are some free slots available.

[ispro]

We have available install slots for Sunday. We install 5.8.7 version with custom patchset. Contact us to schedule your install today! We also provide management services so feel free to let us know your needs and get a quote.

Howcome you only configure nginx to serve static content? What about dynamic content?

[ispro]

Nginx configured to:
1) Serve static files for domain if files are exist on disk;
2) If not, request passed to backend (Apache);
3) If domain not exists in Nginx config all requests passed to backend.

To conclude you shouldn't miss requests having Nginx installed in front of your Apache.

Is "you shouldn't miss requests" equals to: "you will not miss any requests, static or otherwise, 100% guaranteed"?

What exactly constitutes static files? Are PHP, JSP, ASP files without database connections considered as static or dynamic?

Also, is it more efficient to have 2 physical servers, one setup to serve only ngnix and one with just apache installed, than having 1 physical server with both systems on it?

Perhaps, 99,99%, not 100% - additional layer can't improve reliability in perfect (!) world and add some overhead.

But in real world you may get, say 99,98% with Nginx+Apache and 99,5% with Apache just because you will eat lesser RAM with Nginx. Btw, that's why we process static files via Nginx - these files delivery doesn't depend on Apache functionality.

Here is the current list:
css|xml|rss|gif|jpg|jpeg|js|atom|mml|txt|jad|wml|h tc|png|tif|tiff|wbmp|ico|jng|bmp|svg|pdf

PHP, html, etc. files considered dynamic as they may have directives inside, etc. It may be fine-tuned for specific hosts, especially when you know your site very well.

It depends on your usage. Having dedicated Nginx/HAProxy server is nice idea when you have at least 2 backend servers. Otherwise it has little sense and you better to have Nginx on the same server to speed up internal communications.

so can you configure nginx so it serves dynamic files(PHP,html etc) too without using Apache?
