HAProxy – Надежный, высокопроизводительный балансировщик нагрузки для TCP/HTTP
Пока я проводил тестирование производительности различных схем запуска проектов на Ruby on Rails, я наткнулся на очень интересное ПО – HAProxy.
HAProxy is a TCP/HTTP reverse proxy which is particularly suited for high
availability environments. Indeed, it can :
– route HTTP requests depending on statically assigned cookies ;
– spread the load among several servers while assuring server persistence
through the use of HTTP cookies ;
– switch to backup servers in the event a main one fails ;
– accept connections to special ports dedicated to service monitoring ;
– stop accepting connections without breaking existing ones ;
– add/modify/delete HTTP headers both ways ;
– block requests matching a particular pattern ;It needs very little resource. Its event-driven architecture allows it to easily
handle thousands of simultaneous connections on hundreds of instances without
risking the system’s stability.
Что касается меня, я был очень впечатлен производительностью HAProxy и хочу посоветовать Вам попробовать его в своих проектах, связанных с high-availability решениями. Данный балансировщик обладает очень хорошей производительностью и набором функциональности – взгляните на него и, возможно, он сможет помочь Вам сделать вашу систему быстрее и стабильнее!

Willy Tarreau made this software, and he’s our new 2.4 kernel maintainer. That sounds prommising
Yeah! And IMHO, this software has really great internal architecture!
I completly agree.
Hi …
)
I’ve heard so much of HA Proxy … many websites talks about it, recomment to use it … I have checked the web sites, read the manuals and … guess what … not a single example or configuration file in the whole world wide web
any one knows of some samples on how to use it?
thanks,
Jean

On this article you may find example of configuration HAProxy^:

This software seems perfect for my needs but after studying the readme’s and docs for an hour I am no closer to even understanding how you install it. I checked out the above article but that’s Debian and I’m running Centos 5.1, I tried running it install as:
make TARGET=linux26 CPU=i686 REGEX=static-pcre
..but that does not work for some reason
.
Hi IAN, just go to http://haproxy.1wt.eu/ and download the binary glibc 2.2 version, and run it! You don’t even need to compile it
I have chosen HAProxy for a site that is launching next week.
16 APP Servers handling the donations for a major fund raising event. Last year they took $6 million.
Oh and the site is only up for 5 hours
It’s an excellent piece of software, I’m very very surprised at the performance and ease of use.
