Django在Ubuntu14.04的部署方法
<p><span><strong>第一步。</strong></span></p>
<p>
sudo apt-get update</p>
<p>
sudo apt-get upgrade</p>
<p>
先更新。。</p>
<p>
Django的主流部署方式：nginx+uwsgi+django</p>
<p>
<span><strong>第二步，安装nginx</strong></span></p>
<p>
sudo apt-get install nginx</p>
<p>
安装nginx，如果需要安装最新的nginx需从官网下载源码包进行手动编译。</p>
<p>
nginx的大致文件结构。</p>
<p>
1.配置文件：/etc/nginx</p>
<p>
2.程序：/usr/sbin/nginx</p>
<p>
3.日志：/var/log/nginx/access.log - error.log</p>
<p>
<span><strong>第三步，安装uwsgi</strong></span></p>
<p>
sudo apt-get install python3-dev</p>
<p>
sudo apt-get install python3-pip</p>
<p>
sudo pip3 install uwsgi（此步之前，可以换下pip源以提高下载速度。在~/.pip下创建pip.conf写入</p>
<p>
</p>
<p>
trusted-host = pypi.douban.com</p>
<p>
index-url = http://pypi.douban.com/simple）</p>
<p>
uwsgi是一个web服务器，它实现了WSGI协议、uwsgi、http等协议。Nginx中HttpUwsgiModule的作用是与uWSGI服务器进行交换。</p>
<p>
大致流程是 ： 客户端<==>nginx<==>uwsgi<==>Django。静态请求由Nginx自己处理。非静态请求通过uwsgi传递给Django，由Django来进行处理，从而完成一次WEB请求。</p>
<p>
创建Django测试项目，django-admin startproject mysite，cd mysite，python manage.py startapp demo1。</p>
<p>
<span><strong>第四步，测试uwsgi</strong></span></p>
<p>
在mysite目录下新建测试文件,nano test.py.</p>
<p>

<p>
<span><strong>第六步，配置uwsgi</strong></span></p>
<p>
uwsgi支持通过多种配置文件形式启动，这里采用ini配置文件的方法.</p>
<p>
新建uwsgi:nano uwsgi.ini</p>

</div>
<p>
访问时报错，invalid request block size: 21573 (max 4096)...skip。</p>
<p>
原因是url地址超过4096个字符，原因是我们是用socket的方式启动，将配置文件的socket改为http即可，或者修改buffer-size。</p>
<p>
(建议不做修改，测试时改为http即可，等连接nginx时，改回到socket）</p>
<div class="jb51code">

</div>
</div>
<p>
正式运行时将这句代码加入到uwsgi.ini文件中，访问日志就会后台输出到uwsgi.log</p>
<p>
此时django已经能访问。</p>
<p>
<span><strong>第七步，配置nginx</strong></span></p>
<p>
修改nginx的默认配置文件/etc/nginx/sites-enabled/default</p>
