详解Linux查看程序端口占用情况
<p>今天发现服务器上tomcat 8080端口起不来，老提示端口已经被占用。</p>
<p>
使用命令：</p>
<div class="jb51code">
<div>
<div class="syntaxhighlighterbash" id="highlighter_857434">
<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 functions">ps</code> <code class="bash plain">-aux | </code><code class="bash functions">grep</code> <code class="bash plain">tomcat</code>
</div>
</div>
</td>
</tr></tbody></table>
</div>
</div>
</div>
<p>
发现并没有8080端口的tomcat进程。</p>
<p>
使用命令：</p>
<div class="jb51code">
<div>
<div class="syntaxhighlighterbash" id="highlighter_738872">
<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 functions">netstat</code> <code class="bash plain">–apn</code>
</div>
</div>
</td>
</tr></tbody></table>
</div>
</div>
</div>
<p>
查看所有的进程和端口使用情况。发现下面的进程列表，其中最后一栏是pid/program name </p>

<p>
发现8080端口被pid为9658的java进程占用。</p>
<p>
进一步使用命令：</p>
<div class="jb51code">
<div>
<div class="syntaxhighlighterbash" id="highlighter_962973">
<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 functions">ps</code> <code class="bash plain">-aux | </code><code class="bash functions">grep</code> <code class="bash plain">java</code>
</div>
</div>
</td>
</tr></tbody></table>
</div>
</div>
</div>
<p>
或者直接：</p>
<div class="jb51code">
<div>
<div class="syntaxhighlighterbash" id="highlighter_528084">
<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 functions">ps</code> <code class="bash plain">-aux | </code><code class="bash functions">grep</code> <code class="bash plain">pid</code>
</div>
</div>
</td>
</tr></tbody></table>
</div>
</div>
</div>

<p>
就可以明确知道8080端口是被哪个程序占用了！然后判断是否使用kill命令干掉！</p>
<p>
<strong>方法二：直接使用 </strong></p>
<div class="jb51code">
<div>
<div class="syntaxhighlighterbash" id="highlighter_596123">
<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 functions">netstat</code> <code class="bash plain">-anp | </code><code class="bash functions">grep</code> <code class="bash plain">portno</code>
</div>
</div>
</td>
</tr></tbody></table>
</div>
</div>
</div>
<p>
即：</p>
<div class="jb51code">
<div>
<div class="syntaxhighlighterbash" id="highlighter_107584">
<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 functions">netstat</code> <code class="bash plain">–apn | </code><code class="bash functions">grep</code> <code class="bash plain">8080</code>
</div>
</div>
</td>
</tr></tbody></table>
</div>
</div>
