Hello,

A friend of mine has a medium-sized video storage site which gets over 650K daily streams, but he is struggling to keep videos starting/seeking reliably. The site primarily serves large (200MB+) videos and each video typically will have many simultaneous streams - sometimes 500+.
sometimes it can take 30 seconds or longer to start a video. I've tweaked as much as I can on the kernel and nginx, I just wanted to share the configuration here to see if there is anything further I can do to improve the site.

services are on dedicated servers, 1gbps unlimited
quad core: E3-1220 V2 @ 3.10GHz
SATA disks with software raid 1
16GB RAM

nginx config

Code:

worker_processes  2;



worker_rlimit_nofile 60240;

worker_rlimit_sigpending 32768;

error_log  logs/error.log  info;



events {

    worker_connections  4096;

}

    tcp_nopush     on;



    client_body_buffer_size 1K;

    client_header_buffer_size 1k;

    client_max_body_size 1k;

    large_client_header_buffers 2 1k;

    client_body_timeout   10;

    client_header_timeout 10;

    keepalive_timeout     5 5;

    send_timeout          10;



    gzip             on;

    gzip_comp_level  2;

    gzip_min_length  1000;

    gzip_proxied     expired no-cache no-store private auth;

    gzip_types       text/plain application/xml;

    gzip_disable     "MSIE [1-6]\.";

    limit_conn_zone $binary_remote_addr zone=addr:10m;

    perl_modules  perl;

    perl_require  xvs_download.pm;

    include sites/*.conf;

in the sites/ there is an additional config

Code:

    server {

        listen       8777;

        server_name  fs1.local.local;

        proxy_set_header X-Real-IP $remote_addr;

        keepalive_timeout     5 5;

        location / {

               root         /var/www/htdocs;

               access_log   off;

        }



        location ~* "^/(\w{48,})/" {

            perl  xvs_download::handler;

        }



        # MP4 video

        location /download/ {

            internal;

            alias /var/www/cgi-bin/uploads/;

            limit_conn addr 2;

            limit_rate_after 1m;

            limit_rate 180k;

             output_buffers 1 1m;

}

Any assistance would be much appreciated.

Hi , I have Apache 2 running on Ubuntu server, On my site I have multiple web-servers running on windows server . What I'm looking to do is have the Apache box forward the other requested website to the appropriate web-server on site . From reading some other posts in forums its suggests that this can be done by editing the apache2.conf file ? could someone explain step by step how to achieve this please .

Thanks in advance for any help

Dan

Ok, so I've got a Raspberry Pi and a simple c program that turns a stepper motor.
On the stepper motor I have mounted a webcam.
All is working, I can run the program, e.g. sudo ./step -10, to turn the cam 10 steps to the left.

What I want now is to run this via a web page.
So I made a simple script, left10 and put it together with the program (step) in /var/www/cgi-bin:

Code:

#!/bin/sh



echo "test"

foo = `sudo /var/www/cgi-bin/step --v -10`

echo $foo

(--v gives a bit of output, otherwise it's silent)
I get this script running by using URL/cgi-bin/left10, but it only outputs "test", and the motor is not turned.
I have tried various variations, i.e. running directly (not passing the output to $foo), using a relative path etc, but the program (step) is not run.
I have also tried perl, but I'm more comfortable with sh/bash.
(Security etc is not an issue here/now.)
Web server is lighttpd if it matters.

Any pointers?
