<p><span><strong>前言</strong></span></p>
<p>
服务器为Linux-Centos7系统 , 昨天发生了一个非常诡异的情况 , tomcat在已关闭的情况下 , 依然显示其8080端口被占用 , 最后定位到占用端口的进程 , 解决问题 ，下面话不多说了，来一起看看详细的介绍吧。</p>
<p>
<span><strong>1.查看占用端口的进程netstat -lnp|grep 8080</strong></span></p>
<div class="jb51code">
<div>
<div class="syntaxhighlighterbash" id="highlighter_952092">
<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"></code><code class="bash comments"># netstat -lnp|grep 8080</code>
</div>
<div class="line number2 index1 alt1">
<code class="bash plain">tcp6 0 0 :::8080 :::* LISTEN 4486</code><code class="bash plain">/java</code>
</div>
</div>
</td>
</tr></tbody></table>
</div>
</div>
<div class="codetool" id="codetool">

<p>
可以看到 , 是4486的一个java进程占用了8080端口.</p>
<p>
<span><strong>2.查看进程信息 ps 4486</strong></span></p>
<div class="jb51code">

<span><strong>3.强杀进程 kill -9 4486</strong></span></p>
