【Nginx学习】 通过nginx转发访问flask程序

Nginx：

假设已经有一个运行着python程序的Flask程序在运行了，试通过nginx转发，去实现网页的访问

1、安装windows版本的nginx

2、配置nginx：

在server节点中新增一个location】一个upstream节点（注意层级）：

http{
    ......
    server {
    ......
        location /Test{
            proxy_pass http://upstreamname/;   #这里面的最后的斜杠一定不能少
        }
    }

    upstream upstreamname{
        server http://120.0.0.1:5000;
    }
}

upstream 和server同级!!!

3、启动flask的python程序。

4、启动nginx（双击exe文件即可）

5、在浏览器输入nginx服务器地址，加上/Test，即可被nginx转发到对应location所对应的upstream中对应的地址中的资源

6、网页运行结果截图：

# 导入Flask 包
from flask import Flask, redirect, url_for

# 声明Flask的一个对象
app = Flask(__name__)


# 创建路由1
@app.route('/')
