http 서버의 부하 테스트용 도구를 찾을 때 IIJ 사이트에 weighttp라는 도구를 소개했기 때문에 시험해 봤습니다.환경이 CentOS 7인지 확인합니다.

libev 설치

weighttp에서libev를 사용하기 때문에 epel 창고를 추가한 후에libev와libev-devel을 설치합니다.

$ yum install -y epel-release
$ yum install libev libev-devel -y

weighttp의 원본 코드 가져오기

github에서 원본 코드를 얻습니다.

$ cd /usr/local/src
$ git clone https://github.com/lighttpd/weighttp.git

weighttp 구축 설치

weighttp의 구축과 설치는waf를 사용하여 다음과 같이 진행한다.

$ cd weighttp
$ ./waf configure

동작 확인

구축에 성공하면 동작을 확인합니다.
우선, 파라미터가 실행되지 않고 usage에서 명령의 형식을 확인합니다.

$ weighttp
weighttp - a lightweight and simple webserver benchmarking tool

error: missing url argument

weighttp <options> <url>
  -n num   number of requests    (mandatory)
  -t num   threadcount           (default: 1)
  -c num   concurrent clients    (default: 1)
  -k       keep alive            (default: no)
  -6       use ipv6              (default: no)
  -H str   add header to request
  -h       show help and exit
  -v       show version and exit

example: weighttpd -n 10000 -c 10 -t 2 -k -H "User-Agent: foo" localhost/index.html

마지막으로 명령의 실행 예시를 표시하지만, 왜 명령 이름이 틀렸는지 모르겠습니다.
디스플레이 형식을 참고하여 localhost의 httpd에서 weighttp를 실행한 후 다음과 같은 결과를 출력합니다.

$ weighttp -n 10000 -c 10 -t 2 -k -H "User-Agent: foo" localhost/noindex/css/open-sans.css

또한httpd의 로그 파일을 확인한 후 weighttp에서 온 접근 로그를 기록했습니다.

문제 없이 일하는 것 같다
