django+uwsgi+nginx部署

一、nginx安装部署

官方文档:http://nginx.org/

安装当前稳定版本:1.12.2

安装步骤:

#!/bin/bash
nginx_version=nginx-1.12.0
if [ -f "/usr/bin/wget" ];then
  echo "开始下载nginx...."
  wget http://nginx.org/download/$nginx_version.tar.gz
  if [ -f "./$nginx_version.tar.gz" ]; then
  echo "$nginx_version下载完毕!"
  fi
  echo "开始安装nginx依赖包......"
  yum install g++ gcc openssl-devel pcre-devel zlib-devel -y
  echo "解压nginx·......"
  tar xzvf $nginx_version.tar.gz
  echo "开始编译........"
  cd $nginx_version
  ./configure  --prefix=/usr/local/nginx --with-http_stub_status_module --with-http_ssl_module --with-stream --with-stream_ssl_module
  make && make install
  echo "nginx 安装完毕!"
else
  echo "wget is not found!"
fi

启动与停止nginx:

####启动
/usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf

####停止
 /usr/local/nginx/sbin/nginx -s stop
二、uwsgi安装配置

官方文档:http://uwsgi-docs-zh.readthedocs.io/zh_CN/latest/Configuration.html

安装:

###方法一
pip3 install uwsgi
###方法二:
python3 -m pip install uwsgi

 配置uwsgi:uwsgi可支持命令行启动、json格式配置文件启动、ini格式配置文件启动、xml配置文件启动

命令行启动:可以使用uwsgi --help查看启动选项

uwsgi --http :8000 --chdir /opt/app/devops --wsgi-file /opt/app/devops/devops/wsgi.py --master --processes 4 --threads 2 --stats 127.0.0.1:9191

ini配置文件启动:

常用配置参数

http : #协议类型和端口号

processes : #开启的进程数量

workers : #开启的进程数量,等同于processes(官网的说法是spawn the specified number ofworkers / processes)

chdir : #指定运行目录(chdir to specified directory before apps loading)

wsgi-file : #载入wsgi-file(load .wsgi file)

stats : #在指定的地址上,开启状态服务(enable the stats server on the specified address)

threads : #运行线程。由于GIL的存在,我觉得这个真心没啥用。(run each worker in prethreaded mode with the specified number of threads)

master : #允许主进程存在(enable master process)

daemonize : #使进程在后台运行,并将日志打到指定的日志文件或者udp服务器(daemonize uWSGI)。实际上最常用的,还是把运行记录输出到一个本地文件上。

pidfile : #指定pid文件的位置,记录主进程的pid号。

vacuum : #当服务器退出的时候自动清理环境,删除unix socket文件和pid文件(try to remove all of the generated file/sockets)
log-maxsize :#记录日志配置最大多少,超过这个数会切割,单位kb
logto :#指定输出日志到文件logto = /tmp/uwsgi.log

在django项目中与manage.py同级目录创建配置文件,这里命名为uwsgi.ini

# uwsgi 配置文件
[uwsgi]
#端口
socket = :8000
# django项目绝对路径
chdir = /opt/app/devops
# 模块路径(项目名称.wsgi)可以理解为wsgi.py的位置
module = devops.wsgi
# 允许主进程
master = true
#最多进程数
processes  = 4
# 退出时候回收pid文件
vacuum = true
#日志大小配置500M
log-maxsize = 500000000 
#记录日志配置
logto = /tmp/uwsgi.log

启动uwsgi服务

 uwsgi --ini /opt/app/devops/uwsgi.ini --daemonize /tmp/uwsgi.log

 

三、配置nginx

nginx主要位置是代理转发作用

nginx.conf

#user  nobody;
worker_processes  2;

#error_log  logs/error.log;
#error_log  logs/error.log  notice;

pid        logs/nginx.pid;


events {
    worker_connections  1024;
}


http {
    include       mime.types;
    default_type  application/octet-stream;
    access_log  logs/access.log ;
    sendfile        on;
    keepalive_timeout  65;
    gzip  on;
    server {
        listen       80;
        server_name  localhost;
        location / {
            root   html;
            index  index.html index.htm;
        }

        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   html;
        }
      }
    server {
    listen         80; 
    server_name    10.193.15.50;
    charset UTF-8;
    error_log       logs/devops_error.log;

    client_max_body_size 75M;

    location / { 
        include uwsgi_params;
        uwsgi_pass 127.0.0.1:8000;
        uwsgi_read_timeout 5;
    }   
    location /static {
        expires 30d;
        autoindex on; 
        add_header Cache-Control private;
        alias /opt/app/devops/static/;
     }
       }    
}

启动nginx,访问项目url若出现Exception Value: Invalid HTTP_HOST header异常 ,需要在settings.py中ALLOWED_HOSTS = ['*']

重启脚本centos6.x

#!/bin/bash
if [ ! -n "$1" ]
then
    echo "Usages: sh uwsgiserver.sh [start|stop|restart]"
    exit 0
fi

if [ $1 = start ]
then
    psid=`ps aux | grep "uwsgi" | grep -v "grep" | wc -l`
    if [ $psid -gt 4 ]
    then
        echo "uwsgi is running!"
        exit 0
    else
        uwsgi /xxx/www/uwsgi.ini --daemonize /var/log/uwsgi.log --post-buffering 32768 --buffer-size 32768
        echo "Start uwsgi service [OK]"
    fi


elif [ $1 = stop ];then
    killall -9 uwsgi
    echo "Stop uwsgi service [OK]"
elif [ $1 = restart ];then
    killall -9 uwsgi
    uwsgi --ini /xxx/www/uwsgi.ini --daemonize /var/log/uwsgi.log  --post-buffering 32768 --buffer-size 32768 --touch-reload "/xxx/www/reload.set"
    echo "Restart uwsgi service [OK]"

else
    echo "Usages: sh uwsgiserver.sh [start|stop|restart]"
fi
