django+uwsgi+nginx部署网站
静态：nginx直接处理
动态：wsgi或者uwsgi给python处理
uwsgi
web协议，发布python网站。
uwsgi是服务器和服务端应⽤程序的通信协议，规定了怎么把请求转发给应⽤程序和返回
uWSGI实现WSGI协议（应用程序网关接口）
安装uwsgi
pip3 install uwsgi
安装报错：
In file included from plugins/python/pyutils.c:1:0:plugins/python/uwsgi_python.h:2:20: 致命错误：Python.h：没有那个文件或目录#include <Python.h>
安装python-devel 如果是python3则安装python3-devel
yum install python3-devel -y
配置uwsgi
mkdir /etc/uwsgi
vim /etc/uwsgi/uwsgi.ini
配置信息如下
[uwsgi]
uid = root
gid = root
socket = 127.0.0.1:9090
master = true //启动主进程
vhost = true //多站模式
no-site = true //多站模式时不设置⼊⼝模块和⽂件
workers = 2 //⼦进程数
reload-mercy = 10 //平滑的重启
vacuum = true //退出、重启时清理⽂件
max-requests = 1000 //开启10000个进程后, ⾃动respawn下
limit-as = 512 // 将进程的总内存量控制在512M
buffer-size = 30000
pidfile = /var/run/uwsgi9090.pid //pid⽂件，⽤于下⾯的脚本启动、停⽌该进程
daemonize = /var/log/uwsgi9090.log
pythonpath = /root/web/lib/python3.6/site-packages/
启动uwsgi
uwsgi --ini /etc/uwsgi/uwsgi.ini
关闭uwsgi
cat /var/run/uwsgi9090.pid 查看uwsgi的pid
kill -9 101445 杀掉uwsgi
编写uwsgi启动脚本
设置uwsgi服务文件，让uwsgi归systemctl管
创建脚本文件
vim /etc/init.d/uwsgi
chmod 755 /etc/init.d/uwsgi
编写脚本
#!/bin/shDESC="uwsgi daemon"NAME=uwsgiDAEMON=/usr/local/bin/uwsgiCONFIGFILE=/etc/uwsgi/$NAME.iniPIDFILE=/var/run/${NAME}9090.pidSCRIPTNAME=/etc/init.d/$NAMEFIFOFILE=/tmp/uwsgififoset -e[ -x "$DAEMON" ] || exit 0do_start() {if [ ! -f $PIDFILE ];then$DAEMON $CONFIGFILE || echo -n "uwsgi running"elseecho "The PID is exist..."fi}do_stop() {if [ -f $PIDFILE ];then$DAEMON --stop $PIDFILE || echo -n "uwsgi not running"rm -f $PIDFILEecho "$DAEMON STOPED."elseecho "The $PIDFILE doesn't found"fi}do_reload() {if [ -p $FIFOFILE ];thenecho w > $FIFOFILEelse$DAEMON --touch-workers-reload $PIDFILE || echo -n "uwsgi

使用脚本
/etc/init.d/uwsgi status 查看uwsgi服务状态
/etc/init.d/uwsgi start 启动uwsgi服务
/etc/init.d/uwsgi stop 关闭uwsgi服务
/etc/init.d/uwsgi restart 重启uwsgi服务
nginx配置
vim /usr/local/nginx/conf/nginx.conf
即可优化uwsgi服务
server {include uwsgi_params;access_log logs/abc.log main;uwsgi_cache_valid 1m;uwsgi_temp_file_write_size 64k;uwsgi_busy_buffers_size 64k;uwsgi_buffers 8 64k;uwsgi_buffer_size 64k;uwsgi_read_timeout 300;uwsgi_send_timeout 300;uwsgi_connect_timeout 300;listen 80;server_name localhost;location / {include uwsgi_params;uwsgi_pass 127.0.0.1:9090; uwsgi_param UWSGI_SCRIPT baism_web.wsgi;uwsgi_param UWSGI_CHDIR /usr/local/nginx/html/baism_web;index index.html index.htm;client_max_body_size 35m;}
}
代表django web项目，myweb.wsgi代表myweb/myweb/wsgi.py地址
uwsgi_param UWSGI_SCRIPT baism_web.wsgi;
代表网站位置
uwsgi_param UWSGI_CHDIR /usr/local/nginx/html/baism_web;
django配置
将django文件放到nginx的html目录下
mv myweb /usr/local/nginx/html/
启动
启动nginx /usr/local/nginx/sbin/nginx
启动uwsgi /etc/init.d/uwsgi start
netstat -ntpl 检查端口是否开启
注意：
修改nginx配置文件后要重启nginx
修改django,uwsgi配置文件后要重启uwsgi
systemctl restart nginx 重启nginx
systemctl restart uwsgi 重启uwsgi
