<p><strong>简要步骤。（Ubuntu14.04）</strong></p>
<ul>
<li>
Python安装</li>
<li>
Django
</li>
<li>

</ul>
<p>
记录一下我的部署过程，也方便一些有需要的童鞋，大神勿喷~</p>
<p>
<strong>一、Python环境搭建</strong></p>
<p>
操作系统Ubuntu14.04，自带Python2.7.6</p>

</div>
</div>
</div>
<p>
<strong>二、Django环境搭建</strong></p>
<p>
目前Django的版本已经到1.11了。先去官网下载Linux对应的文件，然后解压&安装。（官网下载地址）</p>
<div class="jb51code">
<div>
<div class="syntaxhighlighterbash" id="highlighter_816411">
<div class="toolbar">
<span>?</span>
</div>
<table border="0" cellpadding="0" cellspacing="0"><tbody><tr>
<td class="gutter">
<div class="line number1 index0 alt2">
1</div>
<div class="line number2 index1 alt1">
2</div>
<div class="line number3 index2 alt2">
3</div>
</td>
<td class="code">
<div class="container">
<div class="line number1 index0 alt2">
<code class="bash functions">tar</code> <code class="bash plain">xzvf Django-1.11.x.</code><code class="bash functions">tar</code><code class="bash plain">.gz</code>

<div class="line number3 index2 alt2">
<code class="bash functions">sudo</code> <code class="bash plain">python setup.py </code><code class="bash functions">install</code>
</div>
</div>
</td>
</tr></tbody></table>
</div>
</div>
<div class="codetool" id="codetool">
<div class="code_n">
<textarea></textarea>
</div>
</div>
</div>
<p>
这时可能会提示ImportError： <code>No module named setuptools</code></p>
<p>
执行</p>
<div class="jb51code">
<div>
<div class="syntaxhighlighterbash" id="highlighter_523638">
<div class="toolbar">
<span>?</span>
</div>
<table border="0" cellpadding="0" cellspacing="0"><tbody><tr>

</div>
</div>
</td>
</tr></tbody></table>
</div>
</div>
<div class="codetool" id="codetool">
<div class="code_n">
<textarea></textarea>
</div>
</div>
</div>
<p>
然后执行</p>
<div class="jb51code">
<div>
<div class="syntaxhighlighterpy" id="highlighter_347464">
<div class="toolbar">
<span>?</span>
</div>
<table border="0" cellpadding="0" cellspacing="0"><tbody><tr>
<td class="gutter">
<div class="line number1 index0 alt2">
1</div>
</td>
<td class="code">
<div class="container">
<div class="line number1 index0 alt2">
<code class="py plain">python setyp.py install```</code>
</div>
</div>
</td>
</tr></tbody></table>
</div>
</div>
<div class="codetool" id="codetool">
<div class="code_n">
<textarea></textarea>
</div>
</div>
</div>
<p>
到此Django安装成功～！</p>
<p>
<strong>三、Mysql安装</strong></p>
<p>
执行一下命令，运行过程中可能需要输入root密码并进行确认。</p>
<div class="jb51code">
<div>
<div class="syntaxhighlighterbash" id="highlighter_912633">
<div class="toolbar">
<span>?</span>

</div>
</div>
<div class="codetool" id="codetool">
<div class="code_n">
<textarea></textarea>
</div>
</div>
</div>
<p>
然后链接MySQL和Python</p>
<div class="jb51code">
<div>
<div class="syntaxhighlighterbash" id="highlighter_423461">
<div class="toolbar">

</div>
<p>
进入mysql数据库的方式：</p>

<div class="syntaxhighlighterplain" id="highlighter_669020">
<div class="toolbar">
<span>?</span>

<p>
<strong>四、给mysql设置root密码</strong></p>
<p>
先以第一种方式进入mysql</p>
<div class="jb51code">
<div>
<div class="syntaxhighlighterplain" id="highlighter_140597">
<div class="toolbar">
<span>?</span>
</div>
<table border="0" cellpadding="0" cellspacing="0"><tbody><tr>
<td class="gutter">

</div>
<div class="line number9 index8 alt2">
<code class="plain plain">mysql> exit</code>
</div>
</div>
</td>
</tr></tbody></table>
</div>
</div>
<div class="codetool" id="codetool">
<div class="code_n">
<textarea></textarea>
</div>
</div>
</div>
<p>
括号里面的'root'就是新的密码</p>
<p>
<strong>五、新建项目</strong></p>
<p>
到了验证结果的时候了</p>
<p>
将当前目录切换到Python的worspace下，输入新建的项目名称：</p>
<div class="jb51code">

<ol>
<li>
* __init__.py：Python特性，可以是空文件，表明这个文件夹是一个可以导入的包。</li>
<li>
* settings.py：配置文件，本文主要修改数据库信息、模板目录、加载模块的信息。</li>
<li>

<p>
接下来我们写一个HelloWorld页面。</p>
