gunicorn是一个python Wsgi的WEB服务框架，只支持在Unix系统上运行，来源于Ruby的unicorn项目。虽然可以独自运行，但功能比较单一，通常是部署在Apache，Nginx之后。Gunicorn使用prefork master-worker模型，能够与各种wsgi web框架协作。

安装gunicorn和flask

from flask import Flask, redirect, url_for

app = Flask(__name__)


@app.route('/')  # 首页
def index():
    login_url = url_for('login')
    print("这是首页")
    return redirect(login_url)  # 重定向为登录页面
    return u'这是首页'


@app.route('/login/')  # 登录页面
def login():
    return u'这是登录页面'


@app.route('/question/<is_login>')  # 问答页面
def question(is_login):
    if is_login == '1':
        return u'这是问答页面'
    else:
        return redirect(url_for('login.index'))


if __name__ == '__main__':
    app.run(host='127.0.0.1', port='5008', debug=True)

然后就在shell界面切换到login的目录之下

gunicorn -w 3 -b 0.0.0.0:5008 login:app

备注：

-b 表示 gunicorn 开发的访问地址
-w 表示开启多少个线程
设置0.0.0.0可以监听到所有ip的请求
login.py:app就是那个wsgifunc的名字

端口绑定问题：

linux通常会禁止绑定使用1024以下的端口，除非在root用户权限。

在使用gunicorn时试图将其绑定到80或者443端口，发现无效。

试了使用80端口发现无效

使用petree查看列出关于gunicorn的所有进程
