<p>
本学习主要针对 Centos 7.0.1406 版本进行学习整理！</p>
<p>
1、编辑 ifcfg-eth0 文件，vim 最小化安装时没有被安装，需要自行安装不描述。</p>
<div class="jb51code">
<div>
<div class="syntaxhighlighterbash" id="highlighter_298485">
<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"># vim /etc/sysconfig/network-scripts/ifcfg-eth0</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、修改如下内容</p>
<div class="jb51code">
<div>
<div class="syntaxhighlighterbash" id="highlighter_756171">
<div class="toolbar">
<span>?</span>
</div>

</div>
<div class="line number2 index1 alt1">

</div>
</td>
</tr></tbody></table>
</div>
</div>
<div class="codetool" id="codetool">
<div class="code_n">
<textarea></textarea>
</div>
</div>
</div>
<p>
3、修改后效果</p>
<div class="jb51code">
<div>
<div class="syntaxhighlighterbash" id="highlighter_50132">
<div class="toolbar">
<span>?</span>
</div>

</tr></tbody></table>
</div>
</div>
<div class="codetool" id="codetool">

<p>
4、重启下网络服务</p>
<div class="jb51code">
<div>
<div class="syntaxhighlighterbash" id="highlighter_919684">
<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"># service network restart </code>
</div>
</div>
</td>
</tr></tbody></table>
</div>
</div>
<div class="codetool" id="codetool">
<div class="code_n">
<textarea></textarea>
</div>
</div>
</div>
<p>
5、查看改动后的效果，Centois 7 不再使用 ifconfig 而是用 ip 命令查看网络信息。</p>
