<h2 id="orgheadline1">前言</h2>
<div class="outline-text-2" id="text-1">
<p>
本文是个centos下各个小技巧，小经验的汇总，因为我之前都是接触的ubuntu debian系，所以姑且称这篇文章为入门性质吧。
</p>

<div class="outline-2">
<h2 id="orgheadline4">yum命令</h2>
<div class="outline-text-2" id="text-2">
<p>
在ubuntu下最先接触的就是apt-get命令（ubuntu16之后名字精简为apt了），那么centos下类似的命令就是yum命令。rpm系都可以用yum install来安装一些软件包。
</p>
</div>

<div class="outline-3">
<h3 id="orgheadline2">下载对应的rpm包</h3>
<div class="outline-text-3" id="text-2-1">
<p>
推荐安装 <code>yum-utils</code> 这个软件包：
</p>
<pre>
yum install yum-utils
</pre>

<p>
然后利用其提供的 yumdownloader 命令来下载对应的rpm包。

<div class="outline-3">
<h3 id="orgheadline3">本地源文件安装rpm包</h3>
<div class="outline-text-3" id="text-2-2">
<p>
从本地源文件安装rpm包就是用 rpm命令来安装之：
</p>

<pre>
rpm -i what.rpm
</pre>
