centos+python2+apache2+flask环境搭建

环境：

       1.centos7

        2.python2

        3.flask1.1.2

        4.apache2

1.安装python虚拟环境

pip install virtualenv

2.创建虚拟环境

mkdir flask_project
cd flask_project
virtualenv venv

3.在虚拟环境里安装flask

source source venv/bin/activate
pip install flask

4.创建flask项目

vim app.py

from flask import Flask
app = Flask(__name__)

@app.route('/')
def test1():
        return 'I am a flask example!'
@app.route('/example')
def test2():
        return 'Have a nice day!'
if __name__ == '__main__':
    app.jinja_env.auto_reload = True
    app.config['TEMPLATES_AUTO_RELOAD'] = True
    app.run()

vim wsgi.py

activate_this = '/var/www/html/flask_project/venv/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/html/flask_project')
from app import app as application

5.安装apache

yum install httpd httpd-devel -y

6.安装apache所需的mod_wsgi模块

yum -y install mod_wsgi
#或者pip install mod_wsgi

7.查看apache2是否导入mod_wsgi模块

grep -r 'mod_wsgi.so'  /etc/httpd/

8.如果第7步导入，跳过这一步，否则，手动导入mod_wsgi模块

#在/etc/httpd/conf末尾添加
LoadModule wsgi_module modules/mod_wsgi.so

9.新建一个apache的虚拟主机

我的项目详情：

 vi /etc/httpd/conf.d/flask.conf

<Directory /var/www/html/flask_project>
 <Files wsgi.py>
   Require all granted
 </Files>
</Directory>

WSGIPythonHome /var/www/html/flask_project/venv
WSGIPythonPath /var/www/html/flask_project/venv/lib/python2.7/site-packages
Listen 8080
<VirtualHost *:8080>

ServerName flask.example.com

WSGIScriptAlias / /var/www/html/flask_project/wsgi.py

</VirtualHost>

重启apache

systemctl restart httpd

访问站点测试

curl 127.0.0.1:8080
