• 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
