[uwsgi]
# app.py文件所在目录
chdir = /home/wwwroot/web/pyweb 
callable = app 
# flask文件名
wsgi-file= app.py 
# 进程数
processes = 4
threads = 2
max-requests = 100
vacuum = true
post-buffering=4096
socket  = 127.0.0.1:5000
stats = 127.0.0.1:9010 
# 日志输出目录
daemonize = /home/wwwroot/web/pyweb/pyweb.log 
pidfile = /home/wwwroot/web/pyweb/pyweb.pid

运行uwsgi

1

uwsgi uwsgi.ini

4 安装nginx并编写配置文件

安装nginx

1

yum -y install nginx

配置nginx

1

vim /etc/bin/nginx/nginx.conf

在默认server下添加转发规则，并修改该server的监听端口为8880，以避免与apache端口冲突

server {
    listen 8880;
    location /pyweb/static {
        alias /home/wwwroot/web/pyweb/static;
    }          
    location /pyweb {
        include    /etc/nginx/uwsgi_params;
        uwsgi_pass  127.0.0.1:5000;
        uwsgi_param UWSGI_CHDIR /home/wwwroot/web/pyweb;
        uwsgi_param UWSGI_SCRIPT pyweb:app;            
    }
}

5 编写apache配置文件

apache充当反向代理角色，将所有请求转发给nginx处理，并返回结果,此处8880为nginx的监听端口

ProxyPass /pyweb http://localhost:8880/pyweb 
ProxyPassReverse /pyweb http://localhost:8880/pyweb
