DjangoのインストールとApache連携

【インストール無しの開発環境】

# cd ~/Make
# git clone https://github.com/okoppe8/instant-django.git
# cd instant-django
# python36 -m venv ~/.venv36
# source ~/.venv36/bin/activate
# cat requirements.txt
Django==2.1.2
django-crispy-forms==1.7.2
django-filter==2.0.0
pytz==2018.5
# pip3 install -r requirements.txt # <-- Django環境のインストール
# python36 manage.py migrate
# python36 manage.py createsuperuser
# python36 manage.py runserver

URL=http://127.0.0.1:8000/

【Djangoのインストール】
# python36 -m pip install Django
# ls /usr/local/lib/python3.6/site-packages/django # 確認
$ django-admin.py startproject myapp # プロジェクト作成

$ python36
Python 3.6.6 (default, Aug 13 2018, 18:24:23)
[GCC 4.8.5 20150623 (Red Hat 4.8.5-28)] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import django
>>> django.get_version()
'2.1.2'
$ httpd -v
Server version: Apache/2.4.6 (CentOS)
Server built: Nov 5 2018 01:47:09

# pip3 install
# pip3 install pymysql

■仮想環境の構築
# mkdir /usr/local/venv36
# pip3 -m venv /usr/local/venv36
# source /usr/local/venv36/bin/activate ※環境設定
# deactivate
※環境を戻す

■Apache連携
VENV仮想環境を構築してから下記を行う。

【WSGIインストール】

# pip3 install mod-wsgi
# pip3 freeze|grep wsgi

mod-wsgi==4.6.5
mod-wsgi-httpd==2.4.35.1
# ls /usr/local/venv36/lib64/python3.6/site-packages/mod_wsgi/server/mod_wsgi-py36.cpython-36m-x86_64-linux-gnu.so
# vi /etc/httpd/conf.modules.d/20-wsgi.conf
LoadModule wsgi_module /usr/local/venv36/lib64/python3.6/site-packages/mod_wsgi/server/mod_wsgi-py36.cpython-36m-x86_64-linux-gnu.so
# httpd -M|grep wsgi

# vi /etc/httpd/conf.d/wsgi.conf

# vi /etc/sysconfig/httpd

# curl localhost/myapp
# systemctl restart httpd

※wsgiからstaticが参照できない。
回避????
# vi /etc/httpd/conf.d/wsgi.conf
Alias /static/ /var/www/wsgi/Project/static/
# cd /var/www/wsgi/Project/static
# ln -s /usr/local/venvs/lib/python3.6/site-packages/django/contrib/admin/static/admin admin

試してない
# vi Project/settings.py

※manage.pyに記述した内容をwsgi.pyにも記入。
import io
import pymysql
import cx_Oracle
os.environ["NLS_LANG"] = "JAPANESE_JAPAN.JA16SJISTILDE"
sys.stdout = io.TextIOWrapper(sys.stdout.buffer, encoding='utf-8')

pymysql.install_as_MySQLdb()

【lddコマンドで確認】

※wsgiのインストールは、rootでないとPermission denied.

systemctl restart httpd で「Error: No space left on device」

# systemctl restart httpd
Error: No space left on device
# echo 32768 > /proc/sys/fs/inotify/max_user_watches
で一時的に直る。
恒久的には、
# vi /etc/sysctl.conf
fs.inotify.max_user_watches = 32768 # 追加
# cat /proc/sys/fs/inotify/max_user_watches

※inotify-toolsでファイル、ディレクトリ操作のイベントを監視。

# yum install inotify-tools

# inotifywait ファイル名& -----監視開始

# inotifywatch ファイル名& -----統計情報がとれる。
