linux下如何查看服务器的硬件配置信息
<p>性能测试时一定要确定测试环境和的硬件配置、软件版本配置，保证和线上一致，才更接近真实环境。</p><p>那么linux下如何查看服务器的硬件配置信息？？</p>
<p>一、查看cpu信息</p>
<p><span style="font-family: "Microsoft YaHei"">1、所有信息 lscpu</span></p>
<div class="cnblogs_code">
<pre>#lscpu

</div>
<p>2、查看逻辑cpu的数量</p>
<div class="cnblogs_code">
<pre>cat /proc/cpuinfo |grep <span style="color: rgba(128, 0, 0, 1)">"</span><span style="color: rgba(128, 0, 0, 1)">processor</span><span style="color: rgba(128, 0, 0, 1)">"</span>|sort -u|wc -l</pre>
</div>
<p>3、查看物理cpu的数量</p>
<div class="cnblogs_code">
<pre>grep <span style="color: rgba(128, 0, 0, 1)">"</span><span style="color: rgba(128, 0, 0, 1)">physical id</span><span style="color: rgba(128, 0, 0, 1)">"</span> /proc/cpuinfo|sort -u|wc -l </pre>
</div>
<p>4、查看每个物理cpu的内核数</p>
<div class="cnblogs_code">
<pre>grep <span style="color: rgba(128, 0, 0, 1)">"</span><span style="color: rgba(128, 0, 0, 1)">cpu cores</span><span style="color: rgba(128, 0, 0, 1)">"</span> /proc/cpuinfo|uniq</pre>
</div>
<p>5、每个物理CPU上逻辑CPU个数</p>
<div class="cnblogs_code">
<pre>grep <span style="color: rgba(128, 0, 0, 1)">"</span><span style="color: rgba(128, 0, 0, 1)">siblings</span><span style="color: rgba(128, 0, 0, 1)">"</span> /proc/cpuinfo|uniq</pre>
</div>
<p>6、判断是否开启了抄超线程：</p>
<p>如果多个逻辑CPU的"physical id"和"core id"均相同，说明开启了超线程</p>
<p>或者换句话说</p>
<p> 逻辑CPU个数 > 物理CPU个数 * CPU内核数 开启了超线程</p>
<p> 逻辑CPU个数 = 物理CPU个数 * CPU内核数 没有开启超线程</p>
<p> </p>
<p>二、查看内存信息</p>
<p>1、free -m</p>
<div class="cnblogs_code">
<pre># free -<span style="color: rgba(0, 0, 0, 1)">m
total used free shared buffers cached
Mem: </span><span style="color: rgba(128, 0, 128, 1)">16071</span> <span style="color: rgba(128, 0, 128, 1)">8041</span> <span style="color: rgba(128, 0, 128, 1)">8029</span> <span style="color: rgba(128, 0, 128, 1)">0</span> <span style="color: rgba(128, 0, 128, 1)">143</span> <span style="color: rgba(128, 0, 128, 1)">6487</span>
-/+ buffers/cache: <span style="color: rgba(128, 0, 128, 1)">1411</span> <span style="color: rgba(128, 0, 128, 1)">14659</span><span style="color: rgba(0, 0, 0, 1)">

</div>
<p> </p>
<p>2、查看内存详细信息 cat /proc/meminfo</p>
<div class="cnblogs_code">
<pre># cat /proc/<span style="color: rgba(0, 0, 0, 1)">meminfo
