TDengine--物联网大数据平台初使用（一：安装）

涛思数据的TDengine是创始人陶建辉（Jefft）带领团队开发的物联网大数据平台，据官方https://www.taosdata.com/cn/ 描述不难看出圈内又一大国神器横空出世；恰巧作为一个多年来被动碾转各个技术领域战场的老兵又有了一次亲近物联网项目的契机，看到TDengine，不禁老夫聊发少年狂，技痒难耐，走，粗发：

目前创新互联建站已为上千家的企业提供了网站建设、域名、网页空间、成都网站托管、企业网站设计、怀安网站维护等服务，公司将坚持客户导向、应用为本的策略，正道将秉承"和谐、参与、激情"的文化，与客户和合作伙伴齐心协力一起成长，共同发展。

1. TDengine只支持在使用systemd做进程服务管理的linux系统上安装。

刚从阿里云上申请了台ECS, centos7。

# which systemd

不支持systemd命令；只能源码安装了。

2. 下载源码

进入 https://github.com/taosdata/TDengine 下载源码

3. 安装编译环境

# yum install -y gcc gcc-c++ make automake
# yum -y install cmake

4. 安装java

文档上说：To compile and package the JDBC driver source code, you should have a Java jdk-8 or higher and Apache Maven 2.7 or higher installed. To install openjdk-8 on Ubuntu；

我不用java，但是...我们不得不悲哀的发现：大多数时候，我们不得不向这个世界低头

#yum -y install java-1.8.0-openjdk java-1.8.0-openjdk-devel

再安装 maven
#wget http://repos.fedorapeople.org/repos/dchen/apache-maven/epel-apache-maven.repo -O /etc/yum.repos.d/epel-apache-maven.repo

yum -y install apache-maven

安装完毕查看是否ok:
# mvn -v
Apache Maven 3.5.2 (138edd61fd100ec658bfa2d307c43b76940a5d7d; 2017-10-18T15:58:13+08:00)

OS name: "linux", version: "3.10.0-957.21.3.el7.x8664", arch: "amd64", family: "unix"

5.编译安装TDengine

进入刚才下载的源码根目录
# cd TDengine-master
建立build目录：
TDengine-master]# mkdir build && cd build

编译：
#cmake .. && cmake --build .

等待编译完毕
在 TDengine-master/build 目录中，又发现一个build目录
build]# ll
总用量 64
drwxr-xr-x 4 root root 4096 8月 30 13:00 build

drwxr-xr-x 5 root root 4096 8月 30 13:00 test

继续待在当前目录，安装
build]# make install

6.启动服务
