find mod_wsgi.so from pip install

 $ mod_wsgi-express module-config
 LoadFile "/Users/gree2/anaconda2/envs/dev/lib/libpython2.7.dylib"
 LoadModule wsgi_module "/Users/gree2/anaconda2/envs/dev/lib/python2.7/site-packages/mod_wsgi/server/mod_wsgi-py27.so"
 WSGIPythonHome "/Users/gree2/anaconda2/envs/dev"

config apache

 $ nano /usr/local/etc/httpd/httpd.conf
 ...
 LoadModule wsgi_module "/Users/gree2/anaconda2/envs/dev/lib/python2.7/site-packages/mod_wsgi/server/mod_wsgi-py27.so"

wsgi-scripts

/usr/local/var/www/wsgi-scripts/

 $ cd /usr/local/var/www/
 $ mkdir wsgi-scripts
 $ nano demo.wsgi
 def application(environ, start_response):
     status = '200 OK'
     output = b'hello world'

     response_headers = [('Content-type', 'text/plain'),
                         ('Content-Length', str(len(output)))]
     start_response(status, response_headers)
     return [output]

use a flask app

 # flask app folder
 $ cd /usr/local/var/www/demo

 $ /usr/local/var/www/wsgi-scripts/
 $ nano demo.wsgi
 import sys
 sys.path.append('/usr/local/var/www/demo')
 from demo import manager as application
