보다가 짜증나기 십상이니 보지 마시길...
WSGI(Web Server Gateway Interface)는 python언어에서
웹서버와 웹어플/웹프레임워크 사이를 이어주는 인터페이스다. - PEP333(2010년) 참고.
web server 아파치에서 파이썬으로 웹구현을 하는데는 mod_python모듈도
있지만 더 나은mod_wsgi를 써보자.
wsgi를 지원하는 pytthon framework로는 CherryPy, Django, Tornado, web.py, web2py,
Flask, Pylons, Pyramid, BlueBream,.....
하도 많으니 고르기도 어렵지만 framework을 꼭 써야되는가? 안쓰고는 베길
재간이 없다.
예전에 Flask를 써서 웹으로 원격 GPIO제어를 했었는데 다시 하려니 백지상태로
되버렸다.ㅜ.
자바나 PHP등 웹에 좋은 언어가 많은데 궂이 python으로 하려고 하냐고 묻는다면, 먼저 파이썬으로 만들어진 좋은 어플이나 라이브러리가
있는데 웹에서 처리하고 싶을때 파이슨으로 처리하는것이 가장 좋기 때문이다.
웹서버는 아파치를 쓸거고 파이썬은 3.X를 쓰려고 한다. 파이썬이 2.X버전과 3.X버전이 호환이 안되 버전에 따라 되는지 않되는지 잘
살펴야한다. 라이브러리가 3.X로 만들어 졌는데 framework이 2.X밖에 지원안된다면 내가 라이브러리까지 다 손봐야 한다.
The following packages have unmet
dependencies:
libapache2-mod-wsgi-py3 : Conflicts: libapache2-mod-wsgi but 3.3-4+deb7u1 is
to be installed
E: Unable to correct problems, you have held broken packages.
==> python2.x 와 python3.x는 같이 쓸수 없다는것으로
보인다. 프레임웤이 2.x버전으로 만들어진것과 3.x버전으로 만들어진것을 살펴봐야겟다.
Django(장고)가 요즘 점유율이 높은것같다.
pi@raspberrypi /etc/apache2 $ sudo apt-get install django*
....
0 upgraded, 179 newly installed, 0 to remove and 10 not

허걱!! 179개나!!
그리고 2.x만 지원한듯 보인다. 3.x가 안보임. 게다가 깔야야될 모듈이 너무
어지럽게 널려있어 좀 불안하다.
CherryPy를 찾아보니
A Minimalist Python Web Framework.
Runs on Python 2.5+, 3.1+, PyPy, Jython and Android.
A flexible plugin system.
CherryPy is a pythonic, object-oriented web framework.
이런 말들이 보인다. .. 성능은 모르겟지만 맘에드는 말이 많다.
pi@raspberrypi /etc/apache2 $ sudo apt-cache search cherrypy
python-cherrypy - Python web development framework
python-cherrypy3 - Python web development framework - version 3
python-sponge - Sponge is a web framework built on top of CherryPy and
Genshi
모듈갯수도 작아서 괜찮고,... 깔자

/var/www/html 아래에서 위 네가지언어 아무거나 쓸 수 있다.
아직 django가 어떻게 동작하는지 어떻게 쓰는지 감이 오지 않는다.
지금하고 있는건 장고가 아니고 그냥 wsgi로 python을 쓰는것일뿐 장고의 프레임워크를 쓰는건 아니다.
장고 지우고 다시 python-flask설치
