Introduction

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

How to use

Use Mysql as registry center

If you want to set mysql as the registry center, 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.

1. Open the config

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

registry:
  type: jdbc
  term-refresh-interval: 2s
  term-expire-times: 3
  hikari-config:
    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.

NOTE: You need to add mysql-connector-java.jar into DS classpath, since this plugin will not bundle this driver in distribution. You can get the detail about Initialize the Database

Use Postgresql as registry center

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

1. Initialize the PostgreSQL table

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

1. Open the config

registry:
  type: jdbc
  term-refresh-interval: 2s
  term-expire-times: 3
  hikari-config:
    jdbc-url: jdbc:postgresql://localhost:5432/dolphinscheduler
    username: root
    password: root
    maximum-pool-size: 5
    connection-timeout: 9000
