Flash Video (FLV) Streaming With Nginx

Posted by Oleksiy Kovyrin under Uncategorized · русский

I was looking forward for this feature for last 3 months! And at last, it is there! Now, nginx works on our streaming servers perfectly and flv streaming will not be Lighttpd’s unique feature anymore. :-) This post is about how to use new Nginx module http_flv_module introduced in 0.4.7 (but there was a bug in its implementation, that can be fixed with my patch) and made completely perfect in 0.4.8.

Compiling nginx in RedHat Linux: PCRE library problem

Posted by Oleksiy Kovyrin under Uncategorized

If you will try to compile nginx in Redhat Linux, you can get following error even if you have pcre-devel package installed:

1
2
3
4
5
6
7
8
9
10
Configuration summary
  + threads are not used
  + PCRE library is not found
....
....
./configure: error: the HTTP rewrite module requires the PCRE library.
You can either disable the module by using --without-http_rewrite_module
option, or install the PCRE library into the system, or build the PCRE library
statically from the source with nginx by using --with-pcre=<path> option.
</path>

If you are experiencing this small problem, you should simply use following parameter of configure script:

1
# ./configure --with-cc-opt="-I /usr/include/pcre"

And voila!

  + using system PCRE library

Now it can see and will use system PCRE library.

Looking For Optimal Solution: Benchmark Results Summary and Findings

Posted by Oleksiy Kovyrin under Development · русский

Aftrer my previous post about high-performance RoR deployment methods, I’ve got lots of messages/emails/IM conversations about some errors in previous benchmarks and there were lots of suggestions about extending of tested software set and modifying testing methodology. So, that is why I decided to perform deep and wide performance testing for all deployment schemes I can find. In this article you can find description of testing methodology and, of course, benchmarks results. If you want to know details of specific software setup, take a look at articles in category “Ruby On Rails” to find all articles from “Looking for optimal Solution” series (I’ll post all of them in next few days).

High-Performance Ruby On Rails Setups Test: mongrel vs lighttpd vs nginx

Posted by Oleksiy Kovyrin under Admin-tips, Development, Networks · русский

Because of not fully correct testing methodology, benchmark results are not fully correct. So, I decided to redo all tests. New benchmark results you can get in “Looking For Optimal Solution” series Summary post.

This week we have started one new project with Ruby on Rails as primary framework. My first task was to prepare runtime environment for it on one of our development servers. When I have tried to research how people doing it, I noted that there is no information about how to deploy rails application with nginx as frontend and what is performance of such solution. Before blindly make any decisions about future platform I’ve decided to make some performance tests of the some most popular rails web servers/frontends. Results of these tests you can find here with configuration samples for all software that I have used.

Using Nginx As Reverse-Proxy Server On High-Loaded Sites

Posted by Oleksiy Kovyrin under Networks · русский

Two weeks ago we have started new version of one of our primary web projects and have started very massive advertisement campaign to promote this web site. As the result of that advertisements, our outgoing traffic has been increased to 200-250Mbit/s from only one server! In this article I will describe, how to build stable and efficient web site with two-layer architecture (with frontend + backend web servers) or how to modify your current server configuration to get additional resources to handle more requests.

Monitoring nginx Server Statistics With rrdtool

Posted by Oleksiy Kovyrin under Development, Networks · русский

Few days ago I have installed nginx on one of our adult projects as reverse proxy server and for static files management. Yesterday this server got 200Mbit/sec traffic and because all admins like to create miscellaneous graphs, I have decided to draw nginx stats on graphs to see server load not only in megabits and load averages. As the result, I have created perl script, which uses RRDs perl module to create and manage rrd-database and very beautiful graphs.

Nginx – Small, But Very Powerful and Efficient Web Server

Posted by Oleksiy Kovyrin under Networks · русский

Today, I want to describe one of the interesting tools I am using in my job. This tool is nginx – small, but very powerful and efficient web server created by Igor Sysoev for large Russian web company Rambler and kindly provided by open-source community. This server can be used as standalone HTTP-server and as reverse proxy server before some Apache or another “big” server” to reduce load to backend server by many concurrent HTTP-sessions. As standalone web server, nginx can easily handle huge http-load on static files (images, html-pages, etc).
