解决Ubuntu 16.04下提示boot分区空间不足的办法
<p><span><strong>前言</strong></span></p>
<p>
因为linux内核一直在更新，更新后，旧的内核就不在使用，但旧的内核文件还在boot里面，占据着空间，更新几次过后boot分区就会被占满，显示boot磁盘空间不足。</p>
<p>
<span><strong>解决办法</strong></span></p>
<p>
将不用的内核文件删除，释放空间。</p>
<p>
<span><strong>步骤如下</strong></span></p>
<p>
一、查看已安装的内核<code>dpkg --get-selections |grep linux-image</code></p>
<div class="jb51code">

<div class="line number10 index9 alt1">

<div class="line number11 index10 alt2">

<div class="line number12 index11 alt1">

<div class="line number13 index12 alt2">

<div class="line number14 index13 alt1">

</td>
<td class="code">
<div class="container">
<div class="line number1 index0 alt2">

<div class="line number4 index3 alt1">

<div class="line number5 index4 alt2">

<div class="line number13 index12 alt2">

</div>
<div class="line number14 index13 alt1">
<code class="bash plain">eason@eason:~$</code>
</div>
</div>
</td>
</tr></tbody></table>
</div>
</div>
<div class="codetool" id="codetool">
<div class="code_n">
<textarea></textarea>
</div>
</div>
</div>
<p>
后面带<code>deinstall</code>的为已删除的内核，可以忽略</p>
<p>
二、使用<code>uname -a</code>查看自己当前启动的是哪个内核</p>
<div class="jb51code">
<div>
<div class="syntaxhighlighterbash" id="highlighter_343740">
<div class="toolbar">
<span>?</span>
</div>
<table border="0" cellpadding="0" cellspacing="0"><tbody><tr>
<td class="gutter">
<div class="line number1 index0 alt2">
1</div>
<div class="line number2 index1 alt1">
2</div>
</td>
<td class="code">
<div class="container">
<div class="line number1 index0 alt2">
<code class="bash plain">eason@eason:~$ </code><code class="bash functions">uname</code> <code class="bash plain">-a</code>
</div>
<div class="line number2 index1 alt1">
<code class="bash plain">Linux eason 4.4.0-62-generic </code><code class="bash comments">#83-Ubuntu SMP Wed Jan 18 14:10:15 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux</code>
</div>
</div>
</td>
</tr></tbody></table>
</div>
</div>
<div class="codetool" id="codetool">
<div class="code_n">
<textarea></textarea>
</div>
</div>
</div>
<p>
从输出可知我们当前启动的内核是<code>4.4.0-62-generic</code></p>
<p>
三、运行<code>apt-get remove</code>命令卸载其他内核，为了保险起见，保留最近的一两个版本。</p>
<div class="jb51code">
<div>
<div class="syntaxhighlighterbash" id="highlighter_940462">
<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>
</td>
<td class="code">
<div class="container">
<div class="line number1 index0 alt2">
<code class="bash functions">sudo</code> <code class="bash plain">apt-get remove linux-image-4.4.0-57-generic</code>
</div>
<div class="line number2 index1 alt1">
<code class="bash functions">sudo</code> <code class="bash plain">apt-get remove linux-image-4.4.0-59-generic</code>
</div>
<div class="line number3 index2 alt2">
<code class="bash functions">sudo</code> <code class="bash plain">apt-get remove linux-image-extra-4.4.0-57-generic</code>
</div>
<div class="line number4 index3 alt1">
<code class="bash functions">sudo</code> <code class="bash plain">apt-get remove linux-image-extra-4.4.0-59-generic</code>
</div>
</div>
</td>
</tr></tbody></table>
</div>
</div>
<div class="codetool" id="codetool">
<div class="code_n">
<textarea></textarea>
</div>
</div>
</div>
<p>
如提示有未卸载干净的可以执行<code>sudo apt-get remove</code>来卸载。</p>
