+# 介绍
+
+这个插件将使用 JDBC 作为注册中心。将使用与 api-server 的 yaml 默认的 DolphinScheduler 相同的数据库配置。
+
+# 如何使用
+
+1. 初始化数据库
+
+- 如果你使用 MySQL，你可以直接执行 SQL 脚本 `src/main/resources/mysql_registry_init.sql`.
+
+- 如果你使用 PostgreSQL，你可以直接执行 SQL 脚本 `src/main/resources/postgresql_registry_init.sql`.
+
+2. 修改配置
+
+需要在 master/worker/api 的 application.yml 中设置属性
+
+```yaml
+registry:
+  type: jdbc
+```
+
+完成这两步后，你就可以启动你的 DolphinScheduler 集群了，你的集群将使用 MySQL 作为注册中心来存储服务器元数据。
+
+注意: 如果您使用mysql数据库，您需要将 `mysql-connector-java.jar` 添加到 DS 的类路径中，因为这个插件不会在发行版中捆绑此驱动程序。
+
+## 可选配置
+
+```yaml
+registry:
+  type: jdbc
+  # Used to schedule refresh the heartbeat.
+  heartbeat-refresh-interval: 3s
+  # Once the client's heartbeat is not refresh in this time, the server will consider the client is offline.
+  session-timeout: 60s
+  # The hikari configuration, default will use the same datasource pool as DolphinScheduler.
+  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
+```
+
+## 对 JDBC 注册中心使用不同的数据库配置
+
+需要在 master/worker/api 的 application.yml 中设置属性
+
+### 使用 MySQL 作为注册中心
+
+```yaml
+registry:
+  type: jdbc
+  heartbeat-refresh-interval: 3s
+  session-timeout: 60s
+  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
+```
+
+### 使用 PostgreSQL 作为注册中心
+
+```yaml

+  type: jdbc
+  heartbeat-refresh-interval: 3s
+  session-timeout: 60s
+  hikari-config:
