<content type="html"><![CDATA[<p>Octopress提供很多的Rake任务去创建post和pages，他还会根据你的posts来生成Category，你可以在atom.xml或者blog/categories/<category>/atom.xml中找到这些内容</p>
<h4>Post</h4>
<p>这些Post页面必须存放在Source/_posts目录下面，并且命名方式和jekyll的命名方式一样，会转换成YYYY-MM-DD-Post-title.markdown，这个文件的名字就是你的blog的url slug，日期帮助你排序这些文章</p>
<figure class='code'><figcaption><span></span></figcaption><div class="highlight"><table><tr><td class="gutter"><pre class="line-numbers"><span class='line-number'>1</span>

<p>如果想使用 http://username.github.io的域名作为你的blog地址的话，首先要创建一个仓库，名字为你的用户id.github.io（比如我的是welsonla.github.io）</p>
<p>用户使用的是Github Pages的master版本下面的public作为你的网站主目录，你可以通过浏览http://username.github.io来查看。如果你想在source这个版本上面维护代码，并且把内容提交到master分支，Octopress有一个命令来帮助你完成这些</p>
<figure class='code'><figcaption><span></span></figcaption><div class="highlight"><table><tr><td class="gutter"><pre class="line-numbers"><span class='line-number'>1</span>
</pre></td><td class='code'><pre><code class='ruby'><span class='line'><span class="n">rake</span> <span class="n">setup_github_pages</span>
</span></code></pre></td></tr></table></div></figure>
<p>然后，他将</p>
<ol>
<li>询问你的github pages的url</li>
<li>将远程的重‘origin’重命名为‘octopress’</li>
<li>在远程的origin讲你的github pages仓库添加进去</li>
<li>切换当前branch从master切换到source</li>
<li>根据你的仓库名，重新配置你的blog地址</li>
<li>在_deploy目录下面设置master分支，用于部署</li>
</ol>
<p>接下来执行</p>
<figure class='code'><figcaption><span></span></figcaption><div class="highlight"><table><tr><td class="gutter"><pre class="line-numbers"><span class='line-number'>1</span>
<span class='line-number'>2</span>
</pre></td><td class='code'><pre><code class='ruby'><span class='line'><span class="n">rake</span> <span class="n">generate</span>
</span><span class='line'><span class="n">rake</span> <span class="n">deploy</span>
</span></code></pre></td></tr></table></div></figure>
<p>这将生成你的blog，并将生成的文件copy到_deploy目录下面,并添加到git，将他们commit和push到master分支上面，稍后，你会收到一份来自github的email告诉你，你的提交已经收到，并且很快将发不到你的web上面</p>
<p>并且，不要忘记提交你的代码到source分支</p>
<figure class='code'><figcaption><span></span></figcaption><div class="highlight"><table><tr><td class="gutter"><pre class="line-numbers"><span class='line-number'>1</span>
<span class='line-number'>2</span>
<span class='line-number'>3</span>
</pre></td><td class='code'><pre><code class='ruby'><span class='line'><span class="n">git</span> <span class="n">add</span> <span class="o">.</span>
</span><span class='line'><span class="n">git</span> <span class="n">commit</span> <span class="o">-</span><span class="n">m</span> <span class="s1">'your message'</span>
</span><span class='line'><span class="n">git</span> <span class="n">push</span> <span class="n">origin</span> <span class="n">source</span>
</span></code></pre></td></tr></table></div></figure>
<h4>自定义域名绑定</h4>
<p>首先你要source目录下面创建一个CNAME，</p>
<figure class='code'><figcaption><span></span></figcaption><div class="highlight"><table><tr><td class="gutter"><pre class="line-numbers"><span class='line-number'>1</span>
</pre></td><td class='code'><pre><code class='ruby'><span class='line'><span class="n">echo</span> <span class="s1">'your-domain.com'</span> <span class="o">>></span> <span class="n">source</span><span class="o">/</span><span class="no">CNAME</span>
</span></code></pre></td></tr></table></div></figure>
<p>之后去你的域名服务商或者你的dns服务商那里创建一条CNAME记录，记录指向的IP为
(不要使用顶级域名指向到pages,要使用二级域名)</p>
<figure class='code'><figcaption><span></span></figcaption><div class="highlight"><table><tr><td class="gutter"><pre class="line-numbers"><span class='line-number'>1</span>
</pre></td><td class='code'><pre><code class='ruby'><span class='line'><span class="mi">207</span><span class="o">.</span><span class="mi">97</span><span class="o">.</span><span class="mi">227</span><span class="o">.</span><span class="mi">245</span>

<content type="html"><![CDATA[<p>大约从去年春节，家里人在耳边提到最多的两个字就是“结婚”。这个我特别敏感，一是还没有准备好，更重要的是毕业到现在，感觉自己发展太缓慢，或者说钱途太烂</p>
<p>今年清明节回家，妈妈说奶奶腿疼，一直身体硬朗的她现在走路也不得不扶着拐杖了。时间过的太快，我还记得上学第一天，奶奶用一块雪糕把我骗去幼儿园去上学。现在我都26岁了，将近二十年的时间已经过去了。</p>
<p>毕业也是三年有余，自认为自己技术能力还行，可是一路走来都是各种坑爹的公司。当身边朋友薪水都五位数的时候，我开始觉得我是不是有点太安于现状，或者太没勇气了。</p>
<p>我只想安安心心的专注做技术.</p>
