FLASK项目中的uwsgi配置,配置的http方式

安装项目的依赖

安装项目依赖到虚拟环境中.首先的激活虚拟环境：

source /home/testenv/bin/activate

一.http 启动

撰写uwsgi配置 ,把配置文件命名为uwsgi.ini

[uwsgi]
http=0.0.0.0:5000
;socket = 81.71.70.7:5000
;virtualenv = /root/py38_env     #支持http+socket两种方式，
chdir =/root/xxxxxxx/flask-celery
module = app
# 配置项目目录
wsgi-file=/root/xxxxx/xxxx/app.py
callable=app
processes = 4
threads = 4
buffer-size = 32768
# 开启master, 将会多开一个管理进程, 管理其他服务进程
master = true
# 退出的时候清空环境变量
vacuum = true
;py-autoreload=1
;daemonize =%(chdir)/uwsgi.log
;thunder-lock = true
#防止惊群
harakiri = 60
#超时时间（秒）
vacuum = true
;touch-logreopen = %(chdir)/logs/touchforlogrotate  # 日志分割监听文件

验证下是否正常启动

uwsgi --ini uwsgi.ini

启动

关闭

杀死uwsgi

kill -9 继承的pid

nginx的相关配置

进入 vi /etc/nginx/nginx.conf文件

http {

        server {
        listen 80 ;
        access_log  /usr/local/nginx/logs/access.log  ;
        error_log   /usr/local/nginx/logs/error.log ;
   # server {

        location / {
                include uwsgi_params ;
        #       include /usr/local/nginx/conf/uwsgi_params ;

                proxy_pass http://81.71.70.7:5000 ;
        #       uwsgi_pass 81.71.70.7:5000 ;
        }
    }
