【米尔MYC-JX8MPQ评测】运行TDengine
<p>因为之前的项目上有用到涛思数据库，后面项目上可能也会用到数据库，所以在这个板子上运行试试看</p><p> </p>
<p>TDengine 社区版是一开源版本，采用的是AGPL许可证，是一个处理中小规模的物联网数据平台。它具备高效处理物联网数据所需要的所有功能，包括:</p>
<ul>
<li>类SQL查询语言来插入或查询数据</li>
<li>支持C/C++, Java(JDBC), Python, Go, RESTful, and Node.JS 等开发接口</li>
<li>通过TDengine Shell或Python/R/Matlab可做各种Ad Hoc查询分析</li>
<li>通过连续查询，支持基于滑动窗口的流式计算</li>
<li>引入超级表，让设备之间的数据聚合通过标签变得简单、灵活</li>
<li>内嵌消息队列，应用可订阅最新的数据</li>
<li>内嵌缓存机制，每台设备的最新状态或记录都可快速获得</li>
<li>无历史数据与实时数据之分，对应用而言，透明且完全一样</li>
<li><strong>分布式架构，支持线性扩展</strong>，以保证任何规模的数据量都可以处理</li>
<li><strong>支持多副本，无单点故障</strong>，以保证系统的高可用与高可靠</li>
</ul>
<p>1 解压TDengine软件（TDengine的软件包我已经编译好了这里直接使用，如果哪位同学也想用的话私信邮箱给我）</p>
<pre>
<code>root@myd-jx8mp:~/TDengine# ls -a
...bincfglib
</code></pre>
<p>2将lib目录下的所有文件拷贝到/usr/lib/目录下面</p>
<pre>
<code>root@myd-jx8mp:~/TDengine# cp lib/* /usr/lib/
</code></pre>
<p>3运行taosd涛思服务端</p>
<pre>
<code>root@myd-jx8mp:~/TDengine/bin# ./taosd
