How to Integrate Dameng Database with Nacos 2.3.2 Using the New DM8 Plugin

Background

Nacos does not support databases other than MySQL by default; you need to inject a custom data‑source plugin via the SPI mechanism so that Nacos can load the plugin at startup.

Method 1: Use nacos.zip to Support Dameng

① Dameng DTS migration script

Dameng DTS can migrate the original MySQL data of Nacos to a Dameng database.

② Add Dameng driver and plugin

Create a

plugins

directory inside the extracted

nacos.zip

and place the required JAR files there.

NACOS Version

Dameng Plugin Version

2.2.0 - 2.3.0

0.0.2

2.3.1 - 2.3.2

0.0.3

Download address: https://repo1.maven.org/maven2/com/pig4cloud/plugin/nacos-datasource-plugin-dm8/

③ Configure connection to Dameng

Edit the

conf/application.properties

file:

<code>spring.datasource.platform=dameng<br/>db.num=1<br/>db.url.0=jdbc:dm://192.168.110.200:5236?schema=nacos<br/>db.user.0=SYSDBA<br/>db.password.0=SYSDBA<br/>db.pool.config.driver-class-name=dm.jdbc.driver.DmDriver</code>

Method 2: Build from Source

Example using the PIG microservice development platform, which runs nacos-console as a sub‑service.

1. Add driver and database plugin to nacos‑console

Edit

pig-register/pom.xml

:

<code><!-- Dameng database plugin --><dependency><groupId>com.pig4cloud.plugin</groupId><artifactId>nacos-datasource-plugin-dm8</artifactId><version>${VERSION}</version></dependency><dependency><groupId>com.dameng</groupId><artifactId>DmJdbcDriver18</artifactId><version>8.1.1.193</version></dependency></code>

2. Use Dameng DTS migration tool

Follow the same migration steps as in Method 1.

3. Configure Nacos datasource connection

Edit

pig-register/application.yml

:

<code>db:<br/>  num: 1<br/>  url:<br/>    0: jdbc:dm://172.27.0.5:5236?schema=nacos<br/>  user: nacos<br/>  password: nacos@123<br/>  pool:<br/>    config:<br/>      driver-class-name: dm.jdbc.driver.DmDriver<br/>spring:<br/>  datasource:<br/>    platform: dameng</code>
