Introduction

This module is the mysql registry plugin module, this plugin will use mysql as the registry center.

How to use

If you want to set the registry center as mysql, you need to do the below two steps:

1. Initialize the mysql table

You can directly execute the sql script src/main/resources/mysql_registry_init.sql.

2. Open the config

You need to set the registry properties in master/worker/api's appplication.yml

registry:
  type: mysql
  term-refresh-interval: 2s
  term-expire-times: 3
  hikari-config:
    driver-class-name: com.mysql.cj.jdbc.Driver
    jdbc-url: jdbc:mysql://127.0.0.1:3306/dolphinscheduler
    username: root
    password: root
    maximum-pool-size: 5
    connection-timeout: 9000
    idle-timeout: 600000

After do this two steps, you can start your DolphinScheduler cluster, your cluster will use mysql as registry center to store server metadata.
