Apache24 + wsgi + Flask on Python3.8部署实践

时间：04-22来源：作者：点击数：

1. 安装Apache2.4

Apache官网没有Windows安装包，只有源码需要自己编，可以下载ApacheHaus编译版

下载：httpd-2.4.46-o111j-x64-vc15.zip https://download.csdn.net/download/fm0517/15466535

解压到本地目录E:\GreenSoftware\Apache24

编辑Apache的配置文件：Apache24/conf/httpd.conf

将

Define SRVROOT "/Apache24"

改为

Define SRVROOT "E:\GreenSoftware\Apache24"

至此可以通过命令/Apache24/bin/httpd.exe启动Apache，然后在浏览器中可以看到Apache的欢迎页面。

如果出现错误，可以检查标准输出或者/Apache24/logs/error.log

常见的错误原因可能是端口号80（或443）被别的进程占用。用命令

netstat -ano|findstr 80

netstat -ano|findstr 443

将对应的进程停掉，然后重启httpd.exe即可。

2. 安装Python-3.8.5

从官网找到python-3.8.5-amd64.exe

点此处下载：https://www.python.org/downloads/windows/

3. 安装mod_wsgi-4.7.1-cp38-cp38-win_amd64.whl

Apache HTTP服务器的mod_wsgi扩展模块,实现了Python WSGI标准,可以支持任何兼容Python WSGI标准的Python应用，当然也包括了Flask。

下载：mod_wsgi-4.7.1-cp38-cp38-win_amd64.whl https://download.csdn.net/download/fm0517/15466562

把下载的.whl文件复制到python38\Scripts下，然后使用pip进行安装

D:\Python38\Scripts>pip install mod_wsgi-4.7.1-cp38-cp38-win_amd64.whl
Processing d:\python38\scripts\mod_wsgi-4.7.1-cp38-cp38-win_amd64.whl
Installing collected packages: mod-wsgi
Successfully installed mod-wsgi-4.7.1
WARNING: You are using pip version 20.3.1; however, version 21.0.1 is available.
You should consider upgrading via the 'd:\python38\python.exe -m pip install --upgrade pip' command.

安装成功后在python38\Scripts下运行

D:\Python38\Scripts>mod_wsgi-express module-config
LoadFile "d:/python38/python38.dll"
LoadModule wsgi_module "d:/python38/lib/site-packages/mod_wsgi/server/mod_wsgi.cp38-win_amd64.pyd"
WSGIPythonHome "d:/python38"

将安装后生成的文件mod_wsgi.cp38-win_amd64.pyd移动到Apache的modules目录下

E:\GreenSoftware\Apache24\modules\mod_wsgi.cp38-win_amd64.pyd

编辑Apache的配置文件：Apache24/conf/httpd.conf

增加模块引入：

LoadModule wsgi_module modules/mod_wsgi.cp38-win_amd64.pyd

去掉模块mod_vhost_alias.so前的注释

LoadModule vhost_alias_module modules/mod_vhost_alias.so

4. 创建Flask项目

目录结构

文件hello.py

from flask import Flask
app = Flask(__name__)


@app.route('/')
def root():
    return '<h1>网站建设中</h1>'


@app.route('/hello')
def hello():
    return '<h1>Hello world!</h1>'


if __name__ == '__main__':
    app.run()

文件wsgi.py

import sys

sys.path.insert(0, "D:/000/testweb")

from hello import app
application = app

5. 将Flask项目配置到Apache中

<VirtualHost *>
    WSGIScriptAlias / D:\000\testweb\wsgi.py
    <Directory 'D:\000\testweb'>
        Require all granted
        Require host ip
    </Directory>
</VirtualHost>
