参考网址：https://thingsboard.io/docs/getting-started-guides/helloworld/

github地主：https://github.com/thingsboard/thingsboard

thingsboard使用了

actor模型:akka

远程调用:gRPC,thrift

持久化:Cassandra（https://cassandra.apache.org/数据存储），datastax（数据访问）

演示环境：https://demo.thingsboard.io/login

服务端安装（rpm安装）：参考文档https://thingsboard.io/docs/user-guide/install/linux/(centos7)

1:thingsboard-1.3.rpm。下载地址https://github.com/thingsboard/thingsboard/releases/download/v1.3/thingsboard-1.3.rpm

2:sudo rpm -Uvh thingsboard-1.3.rpm,报错：java-1.8.0 is needed by thingsboard-0:1.3.0-1.noarch。猜测跟jdk的某些配置有关

sudo alternatives --config java

sudo alternatives --install /usr/bin/java java /usr/jdk1.8.0_60/bin/java 1，错误继续.删除配置

sudo alternatives --remove java /usr/jdk1.8.0_60/bin/java

下载rpm版的jdk安装文件(jdk-8u144-linux-x64.rpm)。

sudo rpm -Uvh jdk-8u144-linux-x64.rpm.sudo rpm -Uvh thingsboard-1.3.rpm执行成功

使用postgres数据库

# Install packages

sudo yum install postgresql-server postgresql-contrib

# Initialize your PostgreSQL DB

sudo postgresql-setup initdb

sudo systemctl start postgresql

# Optional: Configure PostgreSQL to start on boot

sudo systemctl enable postgresql

修改/var/lib/pgsql/data/postgresql.conf

listen_addresses = '*'    

修改pg_hba.conf 

host    all             all             x.x.x.x/32        md5。
