Run python3 Django1.9 with mod_wsgi (deploy)

I summarized the procedure to create a Django deployment environment with mod_wsgi. Since it is a memorandum main, only the procedure is written. If you want to understand it properly, you should read other articles.

environment

• Ubuntu Server 14.04
• python3.5.1 (on pyenv)
• Django1.9.4
• mod_wsgi

Environment

Connect to the Ubuntu server with ssh and prepare the environment.

apache

If you haven't installed apache yet, install it with the following command.

$ sudo apt-get install apache2

python , Django

Then install python from pyenv. See below. (Let's fix the python version to 3.5.1) http://qiita.com/tonkatu05/items/d0422a2050d669c72f54#1-%E7%92%B0%E5%A2%83%E6%A7%8B%E7%AF%89

$ python --version
Python 3.5.1

Also install Django.

$ pip install django==1.9.4

mod_wsgi

Then install mod_wsgi.

$ sudo apt-get install libapache2-mod-wsgi-py3

(* Another method [Install mod_wsgi from source](## Install mod_wsgi from source))

First from Hello World

Create /home/hoge/hello.py.

hello.py

import sys

def application(environ, start_response):
    status = '200 OK'
    output = b'Hello World! python version : ' + sys.version.encode("utf-8")

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

Create /etc/apache2/sites-available/python.conf.

python.conf

LoadModule wsgi_module modules/mod_wsgi.so

WSGIScriptAlias / /home/hoge/hello.py
# WSGIScriptAlias / /home/hoge/TestProject/TestProject/wsgi.py
WSGIPythonPath /home/hoge/TestProject:/home/hoge/.pyenv/versions/3.5.1/lib/python3.5/site-packages

<Directory /home/hoge>
   Require all granted
</Directory>

Reflect the settings.

$ sudo a2ensite python.conf

Restart apache.

$ sudo service apache2 restart

Try accessing from a browser.

Hello World! python version : 3.4.3 (default, Oct 14 2015, 20:31:36) 
[GCC 4.8.4]

Is displayed. (The python version is a mystery)

Run Django

$ cd 
$ django-admin startproject TestProject

Edit /home/hoge/TestProject/TestProject/wsgi.py.

wsgi.py

"""
WSGI config for TestProject project.

It exposes the WSGI callable as a module-level variable named ``application``.

For more information on this file, see
https://docs.djangoproject.com/en/1.9/howto/deployment/wsgi/
"""

import os
import sys

from django.core.wsgi import get_wsgi_application

sys.path.append('home/hoge/TestProject')
sys.path.append('home/hoge/TestProject/TestProject')

os.environ.setdefault("DJANGO_SETTINGS_MODULE", "TestProject.settings")

application = get_wsgi_application()

Edit /etc/apache2/sites-available/python.conf. (Comment out WSGIScriptAlias / /home/hoge/hello.py and Uncomment WSGIScriptAlias / /home/hoge/TestProject/TestProject/wsgi.py)

python.conf

LoadModule wsgi_module modules/mod_wsgi.so

# WSGIScriptAlias / /home/hoge/hello.py
WSGIScriptAlias / /home/hoge/TestProject/TestProject/wsgi.py
WSGIPythonPath /home/hoge/.pyenv/versions/3.5.1/lib/python3.5/site-packages

<Directory /home/hoge>
   Require all granted
</Directory>

$ sudo service apache2 restart

Try accessing from a browser again Success when Django's "It worked!" Screen appears.

Another way

Install mod_wsgi from source

As you can see from the result of hello.py, python version 3.4.3 was used for some reason. If you install mod_wsgi with apt-get, you can't specify the version. I don't know how it works, but there may be some inconvenience due to the difference in version ...? (Knowledge around the version)

So I also tried installing mod_wsgi from source. I understand this quite well. I ended up installing python's 3.5-dev. I felt like I went through the error code and read stack overflow, and I didn't understand the meaning of it.

With the introduction finished, maybe ok with the following steps.

For the time being, delete the installed one. (If installed)

$ apt-get remove libapache2-mod-wsgi-py3
$ pyenv uninstall 3.5.1

Install apache2-dev

$ sudo apt-get install apache2-dev

When I try to install python3.5-dev

$ CONFIGURE_OPTS="--enable-shared" pyenv install 3.5-dev
Cloning https://hg.python.org/cpython...
error: please install `mercurial` and try again

So install mercurial

$ sudo apt-get install mercurial
$ CONFIGURE_OPTS="--enable-shared" pyenv install 3.5-dev

Install mod_wsgi

$ cd 
$ wget https://github.com/GrahamDumpleton/mod_wsgi/archive/4.4.13.tar.gz
$ tar zxvf 4.4.13.tar.gz
$ mv mod_wsgi-4.4.13 /usr/local/src
$ cd /usr/local/src/mod_wsgi-4.4.13
$./configure LDFLAGS='-Wl,-rpath=/home/hoge/.pyenv/versions/3.5-dev/lib'
$ make
$ sudo make install

Apply module to apache

$ sudo a2enmod wsgi

Restart apache

$ sudo service apache2 restart

Summary

It was quite difficult and time-consuming to search for literature. I want to work with someone who is familiar with environment construction next to me ... (_ _) Please let me know if you are doing something strange.
