TDengine--物聯網大數據平臺初使用（一：安裝）

濤思數據的TDengine是創始人陶建輝（Jefft）帶領團隊開發的物聯網大數據平臺，據官方https://www.taosdata.com/cn/ 描述不難看出圈內又一大國神器橫空出世；恰巧作為一個多年來被動碾轉各個技術領域戰場的老兵又有了一次親近物聯網項目的契機，看到TDengine，不禁老夫聊發少年狂，技癢難耐，走，粗發：

1. TDengine只支持在使用systemd做進程服務管理的linux系統上安裝。

剛從阿里云上申請了臺ECS, centos7。

# which systemd

不支持systemd命令；只能源碼安裝了。

2. 下載源碼

進入 https://github.com/taosdata/TDengine 下載源碼

3. 安裝編譯環境

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

4. 安裝java

文檔上說：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...我們不得不悲哀的發現：大多數時候，我們不得不向這個世界低頭

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

再安裝 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

安裝完畢查看是否ok:
# mvn -v

5.編譯安裝TDengine

進入剛才下載的源碼根目錄
# cd TDengine-master
建立build目錄：
TDengine-master]# mkdir build && cd build

編譯：
#cmake .. && cmake --build .

等待編譯完畢
在 TDengine-master/build 目錄中，又發現一個build目錄
build]# ll
總用量 64
drwxr-xr-x 4 root root 4096 8月 30 13:00 build

drwxr-xr-x 12 root root 4096 8月 30 13:00 src
drwxr-xr-x 5 root root 4096 8月 30 13:00 test

繼續待在當前目錄，安裝
build]# make install

6.啟動服務
