# How to Set Up A DNS Clusters in WHM

**Prerequisites**

- Have root access to each server.
- Ensure all servers in the cluster are running cPanel/WHM.
- Verify network connectivity between the servers.
- Decide on the DNS roles for each server (e.g., primary, secondary, standalone).

### **Step 1: Log in to WHM either with the root account. Normally you will use one of the URLs below;**

```
http://your_server_ip:2087

https://your_server_hostname:2087
```

### **Step 2: Enable the DNS Cluster Feature**

1. Log in to WHM on the primary server.
2. Navigate to **Home > Clusters > DNS Cluster**.
3. Click **Enable DNS Clustering**.
4. Save the changes.

---

### **Step 3: Add Servers to the Cluster**

- Go to **Home > Clusters > DNS Cluster** in WHM.

- Under **Manage DNS Cluster**, click **Add a new server**.

- Enter the following details:
  - **Remote server key**: Generate the key from the remote server (explained below).
  - **Server type**: Select the server type (e.g., cPanel).
  - **IP address**: Enter the IP address of the remote server.
  - **DNS role**: Choose the role for the server:
    - **Standalone**: Does not sync with others.
    - **Synchronize Changes**: Syncs changes to this server.
    - **Write-Only**: Changes are sent to this server but not synced back.

- Test the connection and click **Submit**.

### **Step 4: Generate the Remote Access Key**

On the remote server:

1. Log in to WHM.
2. Navigate to **Home > Clusters > Remote Access Key**.
3. Copy the key provided.
4. Paste this key into the **Remote server key** field on the primary server.

---

### **Step 5: Configure Synchronization Settings**

1. On the primary server, go to **Home > Clusters > DNS Cluster**.
2. For each server in the cluster, ensure the synchronization settings align with your requirements:
   - Enable **DNS Synchronization** if needed.
   - Select the desired role (Synchronize Changes or Write-Only).

---

### **Step 6: Verify Cluster Functionality**

1. Create a test DNS zone on one server and check if it synchronizes across the cluster.
2. Use tools like `dig` or `nslookup` to ensure DNS records resolve properly from different servers.

---

### **Step 7: Monitor and Maintain the Cluster**

- Regularly check the cluster status in **Home > Clusters > DNS Cluster**.
- Keep servers updated and ensure proper communication between nodes.

---

### **Conclusion**

Setting up a DNS cluster in WHM improves DNS redundancy, ensures faster resolutions, and reduces downtime risks. By configuring synchronization properly, you can create a robust DNS infrastructure for your hosting environment.
