部署代碼後uWSGI需要重新啟動,關閉系統防火墻或者開放端口

• 系統版本:CentOS7.0
• Python版本:Python3.6.3
• Django版本:2.0.5
• uWSGI版本:2.0.17

• nginx版本1.4.4

  1.安裝需要的依賴

  ```shell
  yum install wget openssl-devel bzip2-devel expat-devel gdbm-devel readline-devel sqlite-devel

yum install libxml*

yum -y install gcc automake autoconf libtool make gcc-c++ glibc libxslt-devel libjpeg libjpeg-devel libpng libpng-devel freetype freetype-devel libxml2 libxml2-devel zlib zlib-devel glibc glibc-devel glib2 glib2-devel bzip2 bzip2-devel ncurses ncurses-devel curl curl-devel e2fsprogs e2fsprogs-devel krb5-devel libidn libidn-devel openssl openssl-devel pcre pcre-devel libmcrypt libmcrypt-devel cmake
```
安裝libxml模塊是為了讓uwsig支持使用“-x"選項，能通過xml文件啟動項目

2.編譯安裝python3

進入目錄，依次執行以下命令：

wget https://www.python.org/ftp/python/3.6.3/Python-3.6.3.tgz
#下載完成後，執行解壓命令：
tar -zxvf Python-3.6.3.tar.gz
cd Python-3.6.3
#將python3安裝到/usr/local/python3/路徑下
./configure --prefix=/usr/local/python3
make && make install
#創建軟連接
ln -s /usr/local/python3/bin/python3.6 /usr/bin/python3
ln -s /usr/local/python3/bin/pip3 /usr/bin/pip3
 

3.安裝Django和uWSGI配置啟動項目xml文件

pip3 install django
pip3 install uwsgi

創建uWSGI軟連接：

ln -s /usr/local/python3/bin/uwsgi /usr/bin/uwsgi3

將你的Django項目放到你想放的路徑下，並在項目裏新建 django_study.xml，內容如下：

<uwsgi>
    <!-- 內部端口，自定義 -->
    <socket>127.0.0.1:8000</socket>
    <!-- 項目路徑 -->
    <chdir>
 
項目的路徑</chdir>
    <module>django_study.wsgi</module>
    <!-- 進程數 -->
    <processes>4</processes>
    <!-- 日誌文件 --> 
    <daemonize>uwsgi.log</daemonize>
</uwsgi>

4.安裝nginx和配置nginx.conf文件

• 安裝nginx

  wget http://nginx.org/download/nginx-1.4.4.tar.gz /usr/local/src
  cd /usr/local/src
  tar xf nginx-1.4.4.tar.gz
  cd nginx-1.4.4
  創建用戶www和用戶組www
  groupadd www
  useradd -g www www
  ./configure --user=www --group=www --prefix=/usr/local/nginx --with-http_stub_status_module --without-http-cache --with-http_ssl_module --with-http_gzip_static_module --with-ipv6
  make && make install

• 配置nginx

  server {
  #暴露給外部訪問的端口
  listen 80; 
  server_name localhost;
  charset utf-8;
  location / {
      include uwsgi_params;
      #外部訪問80就轉發到內部8000
      uwsgi_pass 127.0.0.1:8000; 
  }
  }
  #檢查配置文件是否有誤
  /usr/local/nginx/sbin/nginx -t

  提示nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok
  nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful的話說明配置文件無誤，啟動nginx
  /usr/local/nginx/sbin/nginx

  5.訪問項目頁面

  進入Django項目路徑，執行以下命令：

  uwsgi3 -x django_study.xml
