Nginx+uwsgi+python+flask Environment Building —————— study notes

Build Environment Install dependency package

#yum -y install gcc gcc-c++ zlib zlib-devel openssl openssl-devel pcre pcre-devel GroOP gd libXpm livxslt sqlite-devel

Installing Nginx

#yum -y install nginx

Start Nginx

#systemctl start nginx

Test Nginx

#ps -ef |grep nginx

Download python3.6 Compression Pack

#wget -c https://www.python.org/ftp/python/3.6.0/Python-3.6.0.tgz

Installing python3.6

#tar -xvf Python-3.6.0.tgz
#cd Python-3.6.0
#./congigure --prefix=/usr/local/python3.6 && make && make install

Make a python3.6 link

#ln -s /usr/local/python3.6/bin/python3 /usr/bin/python3

To modify an environment variable:

#vim ~/.bash_profile
PATH=$PATH:%HOME/bin:/usr/local/python3.6/bin

Test python3.6

python -V
Python 3.6.4

Installing the Python module using PIP must use PIP3 and compile the installed python3.6 with the PIP3

#rm -rf /usr/bin/pip
#ln -s /usr/local/python3.6/bin/pip3.6 /usr/bin/pip

Installing flask

#pip install flask

Create a project directory

#mkdir /root/flask_pro

Create a portal file

#vim /root/flask_pro/flask_app.py
from flask import Flask,request
app = Flask(__name__)Br/> ' @app. Route ('/helloworld/') '
def helloword()
return ‘helloword‘
if __name__ == ‘_main_‘ :
app.run(host=‘0.0.0.0‘,port=5000)

Run the Flask app

#python flask_app.py

Install Uwsgi:

pip install uwsgi

Configuration Uwsgi:

vim /root/flask_pro/uwsgi.ini
[uwsgi]
socket=127.0.01:5000
chdir=/root/flask_pro/
wsgi-file=flask_app.py
callable=app
processes=2
threads=2
buffer-size=65536

Modifying a configuration file

#vim /usr/local/nginx/conf/nginx.conf<br/>server { <br/> listen; <br/> server_name www.mdzzzz.cn; <br/> Location/{ <br/> include uwsgi_params; <br/> Uwsgi_pass 127.0.0.1:5000; <br/> } <br/> } `

Python load Uwsgi.ini

#uwsgi -d --ini /root/flask_pro/uwsgi.ini

Do boot start

#vim /etc/rc.local
uwsgi -d --ini /root/flask_pro/uwsgi.ini
#chmod +x /etc/rc.d/rc.local
#systemctl enable rc-local

Re-start Nginx

#systemctl restart nginx
