详解centos7配置本地yum源的方法
<p>最近在使用虚拟机时遇到一些麻烦，因为公司内部有网络管理，所以vm连接不上外网，yum无法安装软件，怎么解决呢？–使用iso做本地yum源，可以解决大部份的包安装。</p>
<p>
vm安装的是centos7。</p>
<p>
1、挂载iso到vm</p>
<div class="jb51code">
<div>
<div class="syntaxhighlighterbash" id="highlighter_135903">
<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>
</td>
<td class="code">
<div class="container">
<div class="line number1 index0 alt2">
<code class="bash comments">#mkdir /mnt/cdrom</code>
</div>
<div class="line number2 index1 alt1">
<code class="bash comments">#mount /dev/cdrom /mnt/cdrom</code>
</div>
</div>
</td>
</tr></tbody></table>
</div>
</div>
<div class="codetool" id="codetool">
<div class="code_n">
<textarea></textarea>
</div>
</div>
</div>
<p>
2、修改yum源配置</p>
<p>
yum源配置目录为“/etc/yum.repo.d/”，网络不可用，所以直接删除掉里面的默认配置“rm -f *”，然后建立本地yum源文件”local.repo”。</p>
<p>
yum源配置文件都是以repo结尾，以下是local.repo的具体内容：</p>
<div class="jb51code">
<div>
<div class="syntaxhighlighterbash" id="highlighter_583496">
<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>
<div class="line number4 index3 alt1">
4</div>
<div class="line number5 index4 alt2">
5</div>
<div class="line number6 index5 alt1">
6</div>
</td>
<td class="code">
<div class="container">
<div class="line number1 index0 alt2">
<code class="bash plain"></code>
</div>
<div class="line number2 index1 alt1">
<code class="bash plain">name=This is a </code><code class="bash functions">local</code> <code class="bash plain">repo</code>
</div>
<div class="line number3 index2 alt2">
<code class="bash plain">baseurl=</code><code class="bash functions">file</code><code class="bash plain">:</code><code class="bash plain">///mnt/cdrom</code>
</div>
<div class="line number4 index3 alt1">
<code class="bash plain">enabled=1</code>
</div>
<div class="line number5 index4 alt2">
<code class="bash plain">gpgcheck=1</code>
</div>
<div class="line number6 index5 alt1">
<code class="bash plain">gpgkey=</code><code class="bash functions">file</code><code class="bash plain">:</code><code class="bash plain">///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7</code>
</div>
</div>
</td>
</tr></tbody></table>
</div>
</div>
<div class="codetool" id="codetool">
<div class="code_n">
<textarea></textarea>
</div>
</div>
</div>
<p>
3、更新yum配置</p>
<div class="jb51code">
<div>
<div class="syntaxhighlighterbash" id="highlighter_822781">
<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>
</td>
<td class="code">
<div class="container">
<div class="line number1 index0 alt2">
<code class="bash comments">#yum clean all</code>
</div>
<div class="line number2 index1 alt1">
<code class="bash comments">#yum makecache</code>
</div>
</div>
</td>
</tr></tbody></table>
</div>
</div>
<div class="codetool" id="codetool">
<div class="code_n">
<textarea></textarea>
</div>
</div>
</div>
<p>
通过上面的步骤操作，已经可以使用本地yum源了。有需要进行安装的软件包就可以直接运行”yum install xxx“进行安装了。</p>
