Use MYSQL Replace H2 Database to Store Metadata(Optional)

MYSQL is a reliable relational database. In addition to default built-in H2 database, HertzBeat allow you to use MYSQL to store structured relational data such as monitoring information, alarm information and configuration information.

If you have the MYSQL environment, can be directly to database creation step.

Install MYSQL via Docker

1. Download and install the Docker environment
   Docker tools download refer to Docker official document。 After the installation you can check if the Docker version normally output at the terminal.

   $ docker -v
   Docker version 20.10.12, build e91ed57
2. Install MYSQl with Docker

   $ docker run -d --name mysql -p 3306:3306 -v /opt/data:/var/lib/mysql -e MYSQL_ROOT_PASSWORD=123456 mysql:5.7
   -v /opt/data:/var/lib/mysql is local persistent mount of mysql data directory. /opt/data should be replaced with the actual local directory.
   use $ docker ps to check if the database started successfully

Database creation

1. Enter MYSQL or use the client to connect MYSQL service
   mysql -uroot -p123456
2. Create database named hertzbeat
   create database hertzbeat;
3. Check if hertzbeat database has been successfully created show databases;

Modify hertzbeat's configuration file application.yml and switch data source

1. Configure HertzBeat's configuration file Modify hertzbeat/config/application.yml configuration file Note⚠️The docker container way need to mount application.yml file locally, while you can use installation package way to unzip and modify hertzbeat/config/application.yml
   Replace spring.database data source parameters, URL account and password.

spring:
  datasource:
    driver-class-name: org.h2.Driver
    username: sa
    password: 123456
    url: jdbc:h2:./data/hertzbeat;MODE=MYSQL

Specific replacement parameters are as follows and you need to configure account according to the mysql environment:

spring:
  datasource:
    driver-class-name: com.mysql.cj.jdbc.Driver
    username: root
    password: 123456
    url: jdbc:mysql://localhost:3306/hertzbeat?useUnicode=true&characterEncoding=utf-8&useSSL=false
