CentOS环境下单独安装apachebench的方法
<p>本文实例讲述了CentOS环境下单独安装apachebench的方法。分享给大家供大家参考，具体如下：</p>
<p>
这两天在测试php性能优化方法。</p>
<p>
为了做压力测试可观察效果，就选择了ApacheBench来作为压力测试工具。其实就是大家常说的ab。</p>
<p>
但是这个工具是安装apache web server的时候自带的，现在我服务器上都是跑nginx。也不想为了用这个工具就再装个apache。所以在用下面方法单独安装ab工具，这里记录下步骤。</p>
<p>
首先安装ab运行需要的软件包apr-util</p>
<div class="jb51code">
<div>
<div class="syntaxhighlighterbash" id="highlighter_388632">
<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 plain">yum </code><code class="bash functions">install</code> <code class="bash plain">apr-util</code>
</div>
</div>
</td>
</tr></tbody></table>
</div>
</div>
<div class="codetool" id="codetool">
<div class="code_n">
<textarea></textarea>
</div>
</div>
</div>
<p>
然后安装一个yum的工具包，为了可以单独弄出来ab。</p>
<div class="jb51code">
<div>
<div class="syntaxhighlighterbash" id="highlighter_615195">
<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 plain">yum </code><code class="bash functions">install</code> <code class="bash plain">yum-utils</code>
</div>
</div>
</td>
</tr></tbody></table>
</div>
</div>
<div class="codetool" id="codetool">
<div class="code_n">
<textarea></textarea>
</div>
</div>
</div>
<p>
上面两个安装好以后，我们开始单独安装ab，其实就是下载到apache的rpm包，然后解压后，cp出来ab工具。</p>
<p>
下载apache的rpm包就交给yumdownloader完成了，下载前我们建立一个临时目录用来存放。</p>
<div class="jb51code">
<div>
<div class="syntaxhighlighterbash" id="highlighter_782146">
<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>
</td>
<td class="code">
<div class="container">
<div class="line number1 index0 alt2">
<code class="bash functions">mkdir</code> <code class="bash plain">httpd</code>
</div>
<div class="line number2 index1 alt1">
<code class="bash functions">cd</code> <code class="bash plain">httpd</code>
</div>
<div class="line number3 index2 alt2">
<code class="bash plain">yumdownloader httpd</code>
</div>
</div>
</td>
</tr></tbody></table>
</div>
</div>
<div class="codetool" id="codetool">
<div class="code_n">
<textarea></textarea>
</div>
</div>
</div>
<p>
下载后，我们对rpm进行解包</p>
<div class="jb51code">
<div>
<div class="syntaxhighlighterbash" id="highlighter_740351">
<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 plain">rpm2cpio httpd-2.2.3-43.el5.centos.3.i386.rpm | cpio -idmv</code>
</div>
</div>
</td>
</tr></tbody></table>
</div>
</div>
<div class="codetool" id="codetool">
<div class="code_n">
<textarea></textarea>
</div>
</div>
</div>
<p>
最后将我们用到的ab拷贝到系统的/usr/bin目录下就可以了。最后再删除临时目录就全部ok了。</p>
<div class="jb51code">
<div>
<div class="syntaxhighlighterbash" id="highlighter_844054">
<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>
</td>
<td class="code">
<div class="container">
<div class="line number1 index0 alt2">
<code class="bash functions">mv</code> <code class="bash plain">usr</code><code class="bash plain">/bin/ab</code> <code class="bash plain">/usr/bin/ab</code>
</div>
<div class="line number2 index1 alt1">
<code class="bash functions">cd</code> <code class="bash plain">..</code>
</div>
<div class="line number3 index2 alt2">
<code class="bash functions">rm</code> <code class="bash plain">-rf httpd</code>
</div>
</div>
</td>
</tr></tbody></table>
</div>
</div>
<div class="codetool" id="codetool">
<div class="code_n">
<textarea></textarea>
</div>
</div>
</div>
<p>
希望本文所述对大家CentOS服务器配置有所帮助。</p>
