CentOS7部署Flask(Apache、mod_wsgi、Python36、venv)
(编辑：jimmy 日期: 2025/2/25 浏览：2)
一、安装Apache
# yum install -y httpd httpd-devel
# systemctl start httpd.service # 启动 # systemctl stop httpd.service # 关闭 # systemctl restart httpd.service # 重启 # systemctl enable httpd.service # 开机自启
防火墙开放80端口
# firewall-cmd --zone=public --add-port=80/tcp --permanent # firewall-cmd --reload
开启Apache，外网已经可以通过ip访问Apache的默认页面了
二、安装Python36、pip3、virtualenv
# yum install -y epel-release # yum install -y python36 # python36 -V Python 3.6.6
# yum install -y python36-setuptools # easy_install-3.6 pip # pip3 -V pip 18.1 from /usr/local/lib/python3.6/site-packages/pip-18.1-py3.6.egg/pip (python 3.6)
# pip3 install virtualenv
三、创建项目
创建flask项目（最简单的，一个项目文件夹、一个启动文件）
# mkdir /var/www/flask_test # 项目文件夹 # vi /var/www/flask_test/app.py # 启动文件
启动文件例子：
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()
在项目文件夹下创建虚拟环境，安装flask
# cd /var/www/flask_test # virtualenv py3env # 创建虚拟环境 # source py3env/bin/activate # 进入虚拟环境 (py3env) # pip install flask # 安装flask (py3env) # deactivate # 退出虚拟环境
四、在虚拟环境中用pip安装mod_wsgi
# yum install -y python36-devel.x86_64 # 一个依赖，不安装的话，下面pip会报错。。 # source py3env/bin/activate # 进入虚拟环境 (py3env) # pip install mod_wsgi # 安装mod_wsgi (py3env) # mod_wsgi-express install-module # 执行该命令，把输出内容复制下来 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 # 退出虚拟环境
修改Apache的配置
# vi /etc/httpd/conf/httpd.conf
复制上面得到的这行内容，添加到配置文件的最后
复制代码 代码如下:LoadModule wsgi_module "/usr/lib64/httpd/modules/mod_wsgi-py36.cpython-36m-x86_64-linux-gnu.so"
五、配置mod_wsgi
# vi /var/www/html/flask_test/app.wsgi
写入以下内容（根据：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 sys sys.path.insert(0, '/var/www/flask_test') from app import app as application
配置Apache
# vi /etc/httpd/conf/httpd.conf
写入以下内容（根据：https://dormousehole.readthedocs.io/en/latest/deploying/mod_wsgi.html#id1）
<VirtualHost *:80>
ServerName example.com
WSGIScriptAlias / /var/www/flask_test/app.wsgi
<Directory /var/www/flask_test>
Require all granted
</Directory>
</VirtualHost>
OK了，启动Apache，通过这台服务器的ip就能访问网页了
测试一些app.py里面写的两个路径
