설치 환경 : 우분투 14.04 64bit

1. HAProxy 다운로드
   1. 다운로드 주소 보기 : http://www.haproxy.org/#down

   2. 현재 최신버전 1.6.4 주소 : http://www.haproxy.org/download/1.6/src/haproxy-1.6.4.tar.gz

   3. 압축 해제 : $ tar zxvf haproxy-1.6.4.tar.gz

2. make로 컴파일 하기

   1. 압축 해제후 README 파일을 열어보면 TARGET를 지정해주라고 나와있음
      

      - linux22 for Linux 2.2
      - linux24 for Linux 2.4 and above (default)
      - linux24e for Linux 2.4 with support for a working epoll (> 0.21)
      - linux26 for Linux 2.6 and above
      - linux2628 for Linux 2.6.28, 3.x, and above (enables splice and tproxy)
      - solaris for Solaris 8 or 10 (others untested)
      - freebsd for FreeBSD 5 to 10 (others untested)
      - netbsd for NetBSD
      - osx for Mac OS/X
      - openbsd for OpenBSD 3.1 and above
      - aix51 for AIX 5.1
      - aix52 for AIX 5.2
      - cygwin for Cygwin
      - generic for any other OS or version.
      - custom to manually adjust every setting

   2. 리눅스 버전 확인하기

      $ uname -a Linux ip-172-31-23-15 3.13.0-74-generic #118-Ubuntu SMP Thu Dec 17 22:52:10 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux

   3. 컴파일하기. 

      1. 나는 3.13.0 이므로 TARGET=linux2628을 지정

      2. USE_PCRE : 펄 호환 정규 표현식을 사용할 경우 USE_PCRE=1
      3. USE_OPENSSL : SSL을 이용할 경우 USE_OPENSSL=1, 이 옵션을 주지 않으면 https를 사용할 수 없음

      4. USE_ZLIB : http 압축을 이용할 경우 USE_ZLIB=1

      5. make 설치 : sudo apt-get install make

      6. gcc 설치 : sudo apt-get install gcc

      7. pcre 설치 : sudo apt-get install libpcre3-dev

      8. openssl 설치 : sudo apt-get install libssl-dev openssl

         $ make TARGET=linux2628 USE_PCRE=1 USE_OPENSSL=1 USE_ZLIB=1       README 내용 중 빌드 예제    For example, I use this to build for Solaris 8 :       $ make TARGET=solaris CPU=ultrasparc USE_STATIC_PCRE=1   And I build it this way on OpenBSD or FreeBSD :       $ gmake TARGET=freebsd USE_PCRE=1 USE_OPENSSL=1 USE_ZLIB=1   And on a classic Linux with SSL and ZLIB support (eg: Red Hat 5.x) :       $ make TARGET=linux26 USE_PCRE=1 USE_OPENSSL=1 USE_ZLIB=1   And on a recent Linux >= 2.6.28 with SSL and ZLIB support :       $ make TARGET=linux2628 USE_PCRE=1 USE_OPENSSL=1 USE_ZLIB=1

3. 설치하기

   $ sudo make install install -d "/usr/local/sbin" install haproxy  "/usr/local/sbin" install -d "/usr/local/share/man"/man1 install -m 644 doc/haproxy.1 "/usr/local/share/man"/man1 install -d "/usr/local/doc/haproxy" for x in architecture close-options configuration cookie-options intro linux-syn-cookies lua management network-namespaces proxy-protocol; do \         install -m 644 doc/$x.txt "/usr/local/doc/haproxy" ; \     done

   
   

4. haproxy 서비스 등록하기, 실행파일 /usr/sbin에 복사하기

   $ sudo cp examples/haproxy.init /etc/init.d/haproxy $ sudo chmod 755 /etc/init.d/haproxy $ sudo cp /usr/local/sbin/haproxy /usr/sbin/

   
   

5. 설정파일 만들어주기

   내용 샘플(http://cbonte.github.io/haproxy-dconv/configuration-1.6.html#2.4) 2.5인데 2.4로 북마크가 잘못걸려있음    $ sudo vi /etc/haproxy/haproxy.cfg    global         daemon         maxconn 256       defaults         mode http         timeout connect 5000ms         timeout client 50000ms         timeout server 50000ms       frontend http-in         bind *:80         default_backend servers       backend servers         server server1 127.0.0.1:8000 maxconn 32

6. 설치 확인 : $ haproxy -v

7. 설치 정보 확인 : $ haproxy -vv

1. 빌드시 옵션이 제대로 적용되었나 확인

2. HA-Proxy version 1.6.3 2015/12/25
