First, install Apache

# yum install-y httpd httpd-devel# systemctl start httpd.service # Startup # systemctl stop httpd.service # shutdown # systemctl restart httpd.service # restart # systemctl enable httpd.service # Boot

Firewall opens port 80

# firewall-cmd-zone=public-add-port=80/tcp-permanent# firewall-cmd-reload

Enable Apache, and the public network can already access the default page of Apache through ip.

Second, install Python36, pip3, virtualenv

# yum install- y epel-release# yum install- y python36# python36- VPython 3.6.The yum install- y python36-setuptools# easy_install-3.6 pip# pip3-Vpip 18.1 from / usr/local/lib/python3.6/site-packages/pip-18.1-py3.6.egg/pip (python3.6) # pip3 install virtualenv

Third, create a project

Create a flask project (at its simplest, one project folder, one startup file)

# mkdir / var/www/flask_test # Project folder # vi / var/www/flask_test/app.py # Startup File

Example of startup file:

From flask import Flask, request app = Flask (_ _ name__) @ app.route ('/') def hello_world (): return 'Hello World' @ app.route (' / hello') def hello (): name = request.args.get ('name','') return' Hello'+ name +'! If _ _ name__ = ='_ _ main__': app.run ()

Create a virtual environment under the project folder and install flask

# cd / var/www/flask_test# virtualenv py3env # create a virtual environment # source py3env/bin/activate # enter the virtual environment (py3env) # pip install flask # install flask (py3env) # deactivate # exit the virtual environment

4. Install mod_wsgi with pip in virtual environment

# yum install-y python36-devel.x86_64 # A dependency. If not installed, the following pip will report an error. # source py3env/bin/activate # enter the virtual environment (py3env) # pip install mod_wsgi # install mod_wsgi (py3env) # mod_wsgi-express install-module # execute this command Copy the output LoadModule wsgi_module "/ usr/lib64/httpd/modules/mod_wsgi-py36.cpython-36m-x86_64-linux-gnu.so" WSGIPythonHome "/ var/www/flask_test/py3env" (py3env) # deactivate # exit the virtual environment

Modify the configuration of Apache

# vi / etc/httpd/conf/httpd.conf

Copy the line above and add it to the end of the configuration file

The copy code is as follows: LoadModule wsgi_module "/ usr/lib64/httpd/modules/mod_wsgi-py36.cpython-36m-x86_64-linux-gnu.so"

5. Configure mod_wsgi

# vi / var/www/html/flask_test/app.wsgi

Write the following (according to: https://dormousehole.readthedocs.io/en/latest/deploying/mod_wsgi.html)

Activate_this ='/ var/www/flask_test/py3env/bin/activate_this.py'with open (activate_this) as file_: exec (file_.read (), dict (_ _ file__=activate_this)) import syssys.path.insert (0,'/ var/www/flask_test') from app import app as application

Configure Apache

# vi / etc/httpd/conf/httpd.conf

Write the following (according to: https://dormousehole.readthedocs.io/en/latest/deploying/mod_wsgi.html#id1)

ServerName example.com WSGIScriptAlias / / var/www/flask_test/app.wsgi Require all granted

OK, start Apache, and you can access the web page through the ip of this server

Test the two paths written in some app.py
