centOS7 system系统服务脚本：

#cat uwsgi.service

测试服务：

#uwsgi --ini /djproject/mysite/uwsgi.ini    #启动服务

#ps -ef|grep "uwsgi"  #查看进程

#netstat -lntp|grep "uwsgi"

看上面进程是少了一个主进程，通过systemctl 查看就清楚了：

#systemctl status -l uwsgi.service
● uwsgi.service - uwsgi service

4、安装nginx

这里采用yum安装nginx：

yum -y install nginx

配置nginx与uwsgi代理：

user nginx;
worker_processes auto;
error_log /var/log/nginx/error.log;
pid /run/nginx.pid;

# Load dynamic modules. See /usr/share/nginx/README.dynamic.
include /usr/share/nginx/modules/*.conf;

events {
    worker_connections 1024;
}
