centos7上部署flask项目 ngnix+uwsgi

项目根目录：/home/lora/test/test1

---|test1

------|test1.py

------|uwsgi.ini

一、安装uwsgi

 pip install uwsgi

二、添加uwsgi配置文件

在根目录下添加uwsgi.ini，内容如下：

 [uwsgi] socket = 127.0.0.1:8001   pythonpath = /home/lora/test/test1   module = test1 callable = app   processes = 4   threads = 2

各参数介绍：
socket：通讯端口，外界可以通过127.0.0.1:8001访问，相当于我们在本地运行flask，并通过127.0.0.1:5000访问；并负责与nginx通信。
pythonpath：项目目录。
module：启动文件的文件名，我们可以在本地用python run.py启动flask项目。
callable：程序内启用的application变量名。
processes：处理器个数。
threads：线程数。

三、启动uwsgi

 uwsgi uwsgi.ini

四、安装nginx

 yum install nginx

五、修改nginx配置文件

配置文件的路径不尽相同，我的在/etc/nginx/nginx.conf。
修改如下（主要在server{......}）：

 # For more information on configuration, see: #   * Official English Documentation: http://nginx.org/en/docs/ #   * Official Russian Documentation: http://nginx.org/ru/docs/  user nginx; worker_processes auto; error_log /var/log/nginx/error.log; pid /run/nginx.pid;  # Load dynamic modules.

六、启动nginx
执行nginx命令。启动后，在浏览器输入http://ip即可查看部署是否成功。

附：
流程（原理）：web请求--->nginx代理--->uwsgi代理--->python项目

uwsgi启动：
