# django+uwsgi+nginx部署网站 #

![format_png][]  
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/sh
     DESC="uwsgi daemon"
     NAME=uwsgi
     DAEMON=/usr/local/bin/uwsgi
     CONFIGFILE=/etc/uwsgi/$NAME.ini
     PIDFILE=/var/run/${NAME}9090.pid
     SCRIPTNAME=/etc/init.d/$NAME
     FIFOFILE=/tmp/uwsgififo
     set -e
     [ -x "$DAEMON" ] || exit 0
     do_start() {
     if [ ! -f $PIDFILE ];then
     $DAEMON $CONFIGFILE || echo -n "uwsgi running"
     else
     echo "The PID is exist..."
     fi
     }
     do_stop() {
     if [ -f $PIDFILE ];then
     $DAEMON --stop $PIDFILE || echo -n "uwsgi not running"
     rm -f $PIDFILE
     echo "$DAEMON STOPED."
     else
     echo "The $PIDFILE doesn't found"
     fi
     }
     do_reload() {
     if [ -p $FIFOFILE ];then
     echo w > $FIFOFILE
     else
     $DAEMON --touch-workers-reload $PIDFILE || echo -n "uwsgi
    can't reload"
     fi
     }
     do_status() {
     ps aux|grep $DAEMON
     }
     case "$1" in
     status)
     echo -en "Status $NAME: \n"
     do_status
     ;;
     start)
     echo -en "Starting $NAME: \n"
     do_start
     ;;
     stop)
     echo -en "Stopping $NAME: \n"
     do_stop
     ;;
     reload|graceful)
     echo -en "Reloading $NAME: \n"
     do_reload
     ;;
     *)
     echo "Usage: $SCRIPTNAME {start|stop|reload}" >&2
     exit 3
     ;;
     esac
     exit 0

#### 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
