nginx+uwsgi运行python应用

参考：

http://www.bjhee.com/nginx-uwsgi.html

1、安装uwsgi

pip install uwsgi

(apt install uwsgi)

2、通过http运行一个文件，如test.py

uwsgi --http :80 --wsgi-file test.py --master --processes 4 --threads 2 --stats 127.0.0.1:9090

- -http"参数指定了HTTP监听地址和端口

- -wsgi-file"参数指定了WSGI应用程序入口

uWSGI将启动4个应用进程，每个进程有2个线程，和一个master主进程（监控其他进程状态，如果有进程死了，则重启）

访问"127.0.0.1:9090″来获取JSON格式的应用运行信息

可以把参数写进一个文件中

cat myapp.ini

[uwsgi]

http=:80

wsgi-file=test.py

master=true

processes=4

threads=2

stats=127.0.0.1:9090

启动

uwsgi myapp.ini

3、配置nginx

将uWSGI的HTTP端口监听改为socket端口监听，即将配置文件中的"http"项去掉，改为"socket"项：

[uwsgi]

socket=127.0.0.1:9090

wsgi-file=test.py

master=true

processes=4

threads=2

stats=127.0.0.1:9191

nginx 配置文件中为

location / {

include uwsgi_params;

uwsgi_pass 127.0.0.1:9090;

}

启动

service nginx restart

uwsgi myapp.ini
