 Cluster deployment uses the same scripts and configuration files as [pseudo-cluster deployment](pseudo-cluster.md), so the preparation and deployment steps are the same as pseudo-cluster deployment. The difference is that pseudo-cluster deployment is for one machine, while cluster deployment (Cluster) is for multiple machines. And steps of "Modify Configuration" are quite different between pseudo-cluster deployment and cluster deployment.
 
+## Enable SSL (optional)
+In cluster deployment, you can enable SSL authentication. Secure Sockets Layer, SSL, abbreviated as SSL, is a secure protocol that encrypts transmitted data to ensure that information is not eavesdropped or tampered with during transmission. In addition, it can authenticate servers and ensure data integrity.
+
+To enable SLL authentication, you have two things to do. Firstly, you need to generate `cert.crt` and `private.pem` files.
+
+Step 1: Install OpenSSL
+
+Firstly, ensure that you have installed OpenSSL. In most Linux distributions, OpenSSL is usually pre installed. If not, you can install it using the following command:
+
+On Ubuntu/Debian:
+```bash
+sudo apt-get install openssl
+```
+
+On CentOS/RHEL:
+```bash
+sudo yum install openssl
+```
+Step 2: Generate private key (private.pem)
+
+Open the terminal and run the following command to generate a private key:
+
+```bash
+openssl genpkey -algorithm RSA -out private.pem -pkeyopt rsa_keygen_bits:2048
+```
+
+This command will generate a 2048 bit RSA private key and save it as a private.pem file.
+
+Step 3: Generate Certificate Signing Request (CSR)
+
+Before generating a certificate, you need to generate a Certificate Signing Request (CSR). Run the following command:
+
+```bash
+openssl req -new -key private.pem -out request.csr
+```
+This command will prompt you to enter some information, such as country, state/province, organization name, etc. The information you input will be embedded into the generated certificate.
+
+Step 4: Generate a self signed certificate (cert.crt)
+
+Use CSR to generate self signed certificates. Run the following command:
+```bash
+openssl x509 -req -days 365 -in request.csr -signkey private.pem -out cert.crt
+```
+This command will generate a self signed certificate with a validity period of 365 days and save it as a cert.crt file.
+
+Then modify the `application.yaml` file in the `dolphinscheduler-master`, `dolphinscheduler-worker`, and `dolphinscheduler-api` modules.
+```yaml
+rpc:
+  ssl:
+    enabled: true
+    cert-file-path: /path/cert.crt
+    key-file-path: /path/private.pem
+```
+You need to change `enabled` to `true` and configure the file routing for `cert-file-path` and `key-file-path`.

 ### Prerequisites and DolphinScheduler Startup Environment Preparations
 
 Distribute the installation package to each server of each cluster and perform all the steps in [pseudo-cluster deployment](pseudo-cluster.md) on each machine.

 集群部署(Cluster)使用的脚本和配置文件与[伪集群部署](pseudo-cluster.md)中的配置一样，所以所需要的步骤也与伪集群部署大致一样。区别就是伪集群部署针对的是一台机器，而集群部署(Cluster)需要针对多台机器，且两者“修改相关配置”步骤区别较大
 
+### 开启SSL（可选）
+在集群部署中，你可以开启SSL认证。Secure Sockets Layer，缩写作 SSL，是一种安全协议，能够加密传输的数据，确保在数据传输过程中，信息不会被窃听或篡改，此外还可以对服务器进行身份验证以及保障数据的完整性。
+
+开启SLL认证，你有两件事要做。 首先你需要生成`cert.crt`和`private.pem`文件。
+
+步骤1：安装 OpenSSL
+
+首先，确保您已经安装了 OpenSSL。在大多数 Linux 发行版中，OpenSSL 通常已预装。如果没有，您可以通过以下命令安装它：
+
+在 Ubuntu/Debian 上：
+
+```bash
+sudo apt-get install openssl
+```
+
+在 CentOS/RHEL 上：
+
+```bash
+sudo yum install openssl
+```
+
+步骤 2：生成私钥（private.pem）
+
+打开终端并运行以下命令生成私钥：
+
+```bash
+openssl genpkey -algorithm RSA -out private.pem -pkeyopt rsa_keygen_bits:2048
+```
+此命令会生成一个 2048 位的 RSA 私钥，并将其保存为 private.pem 文件。
+
+步骤 3：生成证书签署请求（CSR）
+
+在生成证书之前，您需要生成一个证书签署请求（CSR）。运行以下命令：
+
+```bash
+openssl req -new -key private.pem -out request.csr
+```
+此命令会提示您输入一些信息，例如国家、州/省、组织名等。您输入的信息将会嵌入到生成的证书中。
+
+步骤 4：生成自签名证书（cert.crt）
+
+使用 CSR 来生成自签名证书。运行以下命令：
+
+```bash
+openssl x509 -req -days 365 -in request.csr -signkey private.pem -out cert.crt
+```
+此命令会生成一个有效期为 365 天的自签名证书，并将其保存为 cert.crt 文件。
+
+然后修改`dolphinscheduler-master`、`dolphinscheduler-worker`、`dolphinscheduler-api`模块中的`application.yaml`文件。
+```yaml
+rpc:
+  ssl:
+    enabled: true
+    cert-file-path: /path/cert.crt
+    key-file-path: /path/private.pem
+```
+您需要将`enabled`改为`true`，同时将配置`cert-file-path`和`key-file-path`的文件路劲。
+
+
