d096 openstack keystone을 windows에서 구동시켜본 적이 있습니다

2018년 qiita라고 하는 일본의 개발자 커뮤니티에서 글을 기재한 적이 있는데, OpenStack keystoneをwindowsで構築してみた 에서 keystone을 윈도우즈에서 구동시켜 본 경험을 적어본 것이었습니다.

왜 했을까.. 뭔가 이유가 있었는데, 한 동안 관계된 일을 하지 않아서 잊고 있었습니다.

윈도우즈에 구축한 이유는 회사에서 지급된 컴퓨터였기 때문에 (늘 사용하는 환경이기 때문에) 윈도우즈를 사용했었던 것 같고, 구동해본 이유는 identity v3의 사양을 확인하기 위해서 였나? 그랬던 것 같습니다.

conda 환경을 사용했고, pycharm으로 break point를 잡아서 디버깅 해 본 겅험입니다.

keystone 설치

처음부터 다시 해봤습니다.

Building wheels for collected packages: netifaces, Yappi

이 패키지를 설치하는 데 실패했습니다. visual c++ 모듈을 필요로 하는 것 같은데요 혹시 conda로 설치할 수 있는 지 해봈습니다.
직접 visual c++ 빌드 툴을 설치하는 방법이 있습니다만, conda 에는 많은 패키지가 바이너리로 빌드되어 준비되어 있는 경우가 많습니다. 그래서 우선 conda를 통해서 설치를 시도해 봤습니다.

conda install -c conda-forge netifaces Yappi

설치가 되네요. 캡춰하려고 했는데, 아웃풋이 사라져 버렸습니다.

다시 pip install -e . 를 실시했더니 성공했습니다.

마지막 부분의 아웃풋만 다시 실펴보면 다음과 같습니다.

wsgi scripts 수정

setup.cfg 파일을 보면 [entry_points] 라고 하는 부분이 있습니다. 윈도우즈의 환경에서 설치하면, console_scripts 에 해당하는 파일들이 생성됩니다만, wsgi_scripts 에 해당되는 파일들은 생성되어 있지 않습니다. 하지만, 리눅스 환경에서 보면 다음과 같이 설치가 되어 있거든요. 이 파일을 복사해 왔습니다.

그리고 윈도우즈에서 실행하려고 했습니다만, python interpreter가 conda완경에 있으므로 shebang을 변경해 놓습니다.
윈도우즈 환경으로 이렇게 python의 interpreter path가 다음과 같이 되어 있다면, 리눅스 식으로 고쳐서 적어 놓습니다.

Queens 버전 전에는 v2 버전에서 35357이라는 포트와 5000 포트로 나누어 실행할 필요가 있었습니다만, v3 이후로는 같은 포트로 5000번 하나만 사용하게 되어있습니다.

pycharm 설정

먼저 interpreter를 설정합니다. conda의 openstack env를 사용합니다. python.exe가 있는 경로를 설정하면 됩니다.

그 다음 run/debug configuraion을 설정합니다. 우리는 keystone-wsgi-public.py 를 실행할 것입니다.

실행을 해보면, 몇개의 패키지가 설치되어 있지 않다고 pycharm이 발견해 주었습니다.

grp, pwd 는 리눅스의 패키지에는 기본적으로 설치되어 있습니다만, 윈도우즈용 파이썬에서는 설치되어 있지 않습니다.

ide의 도움으로 사용하고 있는 함수를 보니, cli툴에서 사용하고 있는 uid, name 의 tuple과 gid, name의 tuple을 돌리고 있는 함수였습니다.
리눅스의 경우를 보니 다음과 같이 설정되어 있어서

tkim@dev-keystone-v110001:/home$ id keystone
uid=110(keystone) gid=117(keystone) groups=117(keystone)
tkim@dev-keystone-v110001:/home$

함수를 커스터 마이징 했습니다.

# import grp
# import pwd

def get_unix_user(user=None):
    return 110, 'keystone'

def get_unix_group(group=None):
    return 117, 'keystone'

예전의 qiita에 기재했을 때는, document가 얘기하는 대로 mysql도 설치하고, apache24도 설치하고 mod_wsgi도 설치하고 해봤습니다만, 이번은 그냥 실행만 해봤습니다. 다음과 같이 breakpoint를 걸고, 멈추는 것 까지 확인했습니다.

아마도 더 진행시키면 데이터베이스가 없어서 어딘가 에러가 발생하겠지만요.
여기까지 keystone을 windows에서 실행시켜본 이야기였습니다.
