title="SmokePing的安装与配置"></a>SmokePing的安装与配置</h1><blockquote><p>sd学校辣鸡网速，实在是不敢恭维，发邮件投诉之后，网信办找到我说：“网速还可以啊！”，这一句话给我怼回来很难受，发现有些东西不去量化实在是不行的。<br>之前想过办法说收集问卷，让集体的声音告诉学校网速真的不行，但是奈何影响力是在不够。感觉不靠谱。<br>然后再网信办发现了官方检测网速的工具，并同时给出了相应的标准。（<a href="http://its.lzu.edu.cn/lzupage/2018/10/11/N20181011121011.html" target="_blank" rel="noopener">网页再此</a>）于是就有了搭建Smokeping这个东西的想法，拿你们的评判标准去评判学生真实使用环境的网速。<br>拿核心节点的服务器去做网速检测就是耍流氓！</p></blockquote><h2 id="What-is-SmokePing"><a href="#What-is-SmokePing" class="headerlink" title="What is SmokePing"></a>What is SmokePing</h2><p>首先回答这是个什么东西，这是个网络连接的嗅探工具。也是从学校网站上发现的，东西很小，还比较好用（<a href="https://oss.oetiker.ch/smokeping/index.en.html" target="_blank" rel="noopener">官网在此</a>），具体的介绍可以看一下，大概就是检测网络状态的，还有一个功能就是发现网络中断可以邮件发你，不过这个我没用，因为学校的网速能连上都算是谢天谢地了，这里只做个网络监测。</p><p>然后这里做一下安装的过程，和踩过的坑，做个笔记</p><h2 id="Prepare-the-environment"><a href="#Prepare-the-environment" class="headerlink" title="Prepare the environment"></a>Prepare the environment</h2><blockquote><p>这玩意没装过，目前也是临时用，所以直接扔到Ubuntu16.04的虚拟机了，apt该更新更新，这里就不再多说了</p></blockquote><p>进官方文档，看环境</p><ul><li>rrdtool: <code>sudo apt install rrdtool librrds-perl libssl-dev</code></li><li>fping(试一下你的fping要求最新的4.2，ATTENTION：不要用旧版本！！！这个自己装)</li><li>curl（这个一般都有，没有的自己装）</li><li>WebServer（我用的nginx，用Apache的也可以，但是太古老，这里不管，nginx安装可以看我的其他post，这里自己装）</li><li>perl >5.10.1: <code>sudo apt install perl</code></li></ul><h2 id="compile-and-Install"><a href="#compile-and-Install" class="headerlink" title="compile and Install"></a>compile and Install</h2><ul><li><code>sudo ./configure --prefix=/opt/smokeping</code></li><li><code>sudo make install</code></li></ul><p>这里装好之后会安装到<code>/opt/smokeping</code>目录下面，自己过去，以下说的所有目录都是基于该目录，例如我说etc目录的时候是<code>/opt/smokeping/etc</code>的目录，不是根目录！</p><p>到此为止smokeping就安装好了</p><p>另外，该项目是基于fcgi的，这也是我用nginx的原因，这里要装个something，让他可以用nginx做反代。</p><ul><li><code>sudo apt install spawn-fcgi</code><br>如何配置我们后面再说。到此为止所有的环境就装好了。</li></ul><h2 id="config"><a href="#config" class="headerlink" title="config"></a>config</h2><p>此处简单介绍如何配置，配置文件的模板是<code>etc/config.dist</code>，copy一份到这里</p><ul><li><code>sudo cp etc/config.dist etc/config</code><br><code>htdocs/smokeping.fcgi.dist</code>的fcgi文件也复制一份：</li><li><code>cp htdocs/smokeping.fcgi.dist htdocs/smokeping.fcgi</code></li></ul><p>在<code>htdocs/</code>下创建文件夹</p><ul><li><code>mkdir {cache,data,var}</code>(htdocs目录下面！)</li></ul><p>修改<code>smokeping_secrets.dist</code>权限</p><ul><li><code>sudo chmod 600 etc/smokeping_secrets.dist</code></li></ul><p>给nginx权限访问<code>htdocs/</code></p><ul><li><code>sudo chown -R nginx.nginx /usr/local/smokeping/htdocs/</code></li></ul><p>这里给一份conf的模板，自己看着改一下，路径啥的<br><figure class="highlight plain"><table><tr><td class="gutter"><pre><span class="line">1</span><br><span
