centos系统搭建本地yum服务器的方法
<p><span><strong>前言</strong></span></p><p>首先特别说明的是，YUM只是为了解决RPM的依赖关系的问题，而不是一种其它的软件安装模式。虽然在centos中可以直接使用yum源，但是也存在着与外网隔绝的现状，因此需要搭建本地yum源，下面来看看详细的方法。</p>
<p><strong>系统：centos 6.5</strong></p>
<p><span><strong>1、将光盘挂载到/mnt下面</strong></span></p>
<div class="jb51code">
<div><div id="highlighter_208215" class="syntaxhighlighterbash">
<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="bash comments"># mount /dev/cdrom /mnt</code></div></div></td>
</tr></tbody></table>
</div></div>
<div class="codetool" id="codetool"><div class="code_n"><textarea></textarea></div></div>
</div>
<p><span><strong>2、删除系统自带的repo文件</strong></span></p>
<div class="jb51code">
<div><div id="highlighter_406609" class="syntaxhighlighterbash">
<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 comments"># cd /etc/yum.repos.d/ </code></div>
<div class="line number2 index1 alt1"><code class="bash comments"># mkdir bak </code></div>
<div class="line number3 index2 alt2"><code class="bash comments"># mv *.repo bak</code></div>
</div></td>
</tr></tbody></table>
</div></div>
<div class="codetool" id="codetool"><div class="code_n"><textarea></textarea></div></div>
</div>
<p><span><strong>3、安装createrepo</strong></span>（其实只要安装createrepo即可以，但是需要其他依赖包，所以也得一起装上）</p>
<div class="jb51code">

<p><span><strong>4、使用createrepo命令创建yum仓库，创建索引信息</strong></span><strong><br></strong></p>
<p><span><strong>注：</strong></span>这里我们把yum仓库建立在/doiido/local</p>
