HAProxy 1.8 소스 인스톨(컴파일) 설치 가이드

HAProxy 는 현재 가장 유명한 소프트웨어 로드발란서 중 하나입니다. L4 뿐 아니라 L7 기능까지 포함하고 있어 많은 곳에서 활용되고 있습니다. HAProxy 의 기능에 대해 설명된 블로그나 사이트는 많기 때문에 여기서는 설치 방법에 대해서만 다루도록 하겠습니다.

이 가이드는 HAProxy 1.8 버전을 사용하였으며 공식 사이트인 HAProxy – The Reliable, High Performance TCP/HTTP Load Balancer 및 HAProxy version 1.8.27 – Starter Guide (cbonte.github.io) 을 참조하였습니다.
