HAProxy 설명

  • L4 (TCP) 및 L7 (HTTP) 기반의 로드밸런싱 및 프록시를 제공하는 오픈소스 소프트웨어
  • C 언어로 개발, 스위치에서 제공하는 L4, L7 기능을 지원
  • reverse proxy의 형태로 동작, Keepalived를 사용하여 HA(high availability) 구성 진행

설치

apt로 설치

1
2

apt-get update
apt-get install -y haproxy

컴파일하여 설치

HAProxy를 직접 컴파일하여 실행하여도 된다.

haproxy config 설정

ssl 세팅을 진행하기 위해서는 인증서를 조합하여 파일을 만들어야 한다.

1
2
3
4

cat "<인증서경로>" "<키경로>" > output.pem
# 예시 (letsencrypt)
# cat fullchain1.pem privkey1.pem > output.pem

/etc/haproxy/haproxy.cfg 파일을 수정하여 설정을 진행한다.
