If you’re not familiar with HAProxy, you’re missing out! HAProxy is a very intelligent high-availability reverse proxy that operates all the way up to Layer 7. Unlike Nginx (another good choice), HAProxy is not a webserver, it is designed with only high availability and load balancing in mind. Another great feature is that it’s a lot cheaper than your typical Layer 7 Load Balancer, free :).
There are plenty of good articles out there on HAProxy, but I couldn’t find any Debian/Ubuntu packages for the latest version (1.4.15). The Ubuntu 11.04 repo’s newest version is 1.4.8, but if you want some of the cool new features of 1.4.9-1.4.15, you have to build it from scratch. This process isn’t too painful, but I’ve got a lot of servers to put HAProxy on and I don’t want
apt-get to freak out and install the old HAProxy in order to satisfy a dependency.
For this reason, I’ve created an Ubuntu 11.04 x64 HAProxy package with TCP Splicing, Full Transparent Proxies and PCRE enabled:
