+
+# Namingserver Registration Center
+Namingserver is the native registration center of Seata.
+
+## Preparations
+You can choose to run the naming server in the compiler or after packaging it.
+
+### Running the naming server in the compiler
+Go to the namingserver directory, set the port number for the naming server in resources/application.yml, and start the naming server.
+
+### Running the naming server after packaging
+Execute the packaging command:
+```shell
+mvn clean install -U -Prelease-seata-namingserver
+```
+Set the naming server port number in the `conf/application.yml` file located in the `\\distribution\\target\\apache-seata-2.2.0-SNAPSHOT-incubating-bin\\seata-namingserver` directory.
+For macOS or Linux, run:
+
+```shell
+bin\\seata-namingserver.sh
+```
+For Windows, run:
+
+```shell
+bin\\seata-namingserver.bat
+```
+## Getting Started Quickly
+The process to use the naming server as Seata's registration center is very simple and involves configuring both the client and server sides.
+
+### Client-side Configuration for the Registration Center
+Add the corresponding registration center in the application.yml:
+
+```yaml
+seata:
+  registry:
+    type: seata
+  seata:
+    server-addr: 127.0.0.1:8081   ## IP + port of the naming server configured in the first step. Use commas to separate multiple naming server nodes.
+    namespace: public  ## Namespace
+    heartbeat-period: 5000  ## Heartbeat interval
+```
+### Server-side Configuration for the Registration Center
+Add the following configuration to `conf/application.yaml`, with the rest of the configuration referring to configuration options:
+
+```yaml
+seata:
+  registry:
+    type: seata
+  seata:
+    server-addr: 127.0.0.1:8081   ## IP + port of the naming server configured in the first step. Use commas to separate multiple naming server nodes.
+    cluster: default  ## Cluster name
+    namespace: public  ## Namespace
+    heartbeat-period: 5000  ## Heartbeat interval
+```
+Create a Mapping Between the Client's Transaction Group and the Seata Cluster
+Send an HTTP request to one naming server node to create a transaction group-to-cluster mapping (the naming server node will automatically synchronize with other nodes):
+
+```shell
+http://127.0.0.1:8081/naming/v1/changeGroup?clusterName=cluster2&namespace=public&unitName&vGroup=my_test_tx_group
+```
+(In this, namespace is the namespace configured on the client side, vGroup is the transaction group configured on the client side, and clusterName is the cluster name on the server side that needs to be mapped.)
+
+Afterward, once Seata-Server is started and the client configuration is complete, you can begin to experience Seata services.
+
+Tips: Ensure that both the client and server are registered under the same namespace; otherwise, the service won't be found.

+
+# Namingserver 注册中心
+
+Namingserver 是 Seata 原生的注册中心.
+
+## 预备工作
+可以选择在编译器中运行namingserver或者打包后运行namingserver
+### 编译器运行namingserver
+
+进入`namingsever`目录，在`resources/application.yml`下设置namingserver启动的端口号，启动namingserver
+
+### 打包运行namingserver
+
+执行`mvn clean install -U -Prelease-seata-namingserver`打包命令
+```shell
+`mvn clean install -U -Prelease-seata-namingserver`
+```
+在`\distribution\target\apache-seata-2.2.0-SNAPSHOT-incubating-bin\seata-namingserver`目录下的`conf/application.yml`中配置namingserver启动的端口号，
+mac或linux运行
+``` shell
+bin\seata-namingserver.sh
+```
+windows环境运行
+``` shell
+bin\seata-namingserver.bat
+```
+
+## 快速上手
+
+Seata 使用 namingserver 作为注册中心的操作步骤非常简单，分为在client端的配置以及在server端的配置
+
+### Client端配置注册中心
+
+在 [**application.yml**](https://github.com/apache/incubator-seata/blob/2.x/script/client/spring/application.yml)
+中加入对应的注册中心。
+
+```yaml
+seata:
+  registry:
+    type: seata
+    seata:
+      server-addr: 127.0.0.1:8081   ##第一步配置的namingserver的ip+端口，若有多个namingserver节点则用逗号分割
+      namespace: public  ##命名空间
+      heartbeat-period: 5000  ##心跳时间
+```
+
+### Server端配置注册中心
+
+在 `conf/application.yaml`加入以下配置,
+其余配置参考 [configuration options](https://github.com/apache/incubator-seata/blob/2.x/server/src/main/resources/application.example.yml):
+
+```yaml
+seata:
+  registry:
+    type: seata
+    seata:
+      server-addr: 127.0.0.1:8081   ##第一步配置的namingserver的ip+端口，若有多个namingserver节点则用逗号分割
+      cluster: default  ##集群名称
+      namespace: public  ##命名空间
+      heartbeat-period: 5000  ##心跳时间
+```
+
+### 创建client端的事务分组->seata集群的映射关系
+向一个namingserver节点发起创建事务分组映射关系的http请求（namingserver节点会自动同步给其它节点）
+```shell
+http://127.0.0.1:8081/naming/v1/changeGroup?clusterName=cluster2&namespace=public&unitName&vGroup=my_test_tx_group
+```
+（其中namespace是client端配置的命名空间，vGroup是client端配置的事务分组，clusterName是需要映射到的server端的集群名称）
+
+随后,启动 Seata-Server 后，Client 配置完成后启动应用就可以正式体验 Seata 服务。
+
+Tips：请确保client与server的注册处于同一个namespace，不然会找不到服务。
