centos7下部署Django（nginx+uWSGI+Python3+Django)

部署代码后uWSGI需要重新启动,关闭系统防火墙或者开放端口

• 系统版本: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.安装需要的依赖

  ```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
```
安装libxml模块是为了让uwsig支持使用“-x"选项，能通过xml文件启动项目

2.编译安装python3

进入目录，依次执行以下命令：

wget https://www.python.org/ftp/python/3.6.3/Python-3.6.3.tgz
#下载完成后，执行解压命令：
tar -zxvf Python-3.6.3.tar.gz
cd Python-3.6.3
#将python3安装到/usr/local/python3/路径下
./configure --prefix=/usr/local/python3
make && make install
#创建软连接
ln -s /usr/local/python3/bin/python3.6 /usr/bin/python3
ln -s /usr/local/python3/bin/pip3 /usr/bin/pip3

3.安装Django和uWSGI配置启动项目xml文件

pip3 install django
pip3 install uwsgi

创建uWSGI软连接：

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

将你的Django项目放到你想放的路径下，并在项目里新建 django_study.xml，内容如下：

<uwsgi>
    <!-- 内部端口，自定义 -->
    <socket>127.0.0.1:8000</socket>
    <!-- 项目路径 -->
    <chdir>项目的路径</chdir>
    <module>django_study.wsgi</module>
    <!-- 进程数 -->
    <processes>4</processes>
    <!-- 日志文件 --> 
    <daemonize>uwsgi.log</daemonize>
</uwsgi>

4.安装nginx和配置nginx.conf文件

• 安装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
  创建用户www和用户组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 {
  #暴露给外部访问的端口
  listen 80; 
  server_name localhost;
  charset utf-8;
  location / {
      include uwsgi_params;
      #外部访问80就转发到内部8000
      uwsgi_pass 127.0.0.1:8000; 
  }
  }
  #检查配置文件是否有误
  /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的话说明配置文件无误，启动nginx
  /usr/local/nginx/sbin/nginx

  5.访问项目页面

  进入Django项目路径，执行以下命令：

  uwsgi3 -x django_study.xml
