Microservices Engine (MSE) provides two consoles for managing Nacos instances:
Enterprise console: The default, fully managed interface with RAM-based access control. Use this console for most management tasks.
Open source console: The native Nacos UI. Use this console when you need Nacos-native workflows that the enterprise console does not support.
The open source console is disabled by default on MSE Nacos 2.2.3.1 and later. Console availability, authentication support, and security requirements differ by version.
Version differences
| MSE Nacos version | Console default status | Authentication | Required action |
|---|---|---|---|
| 1.x and 2.x earlier than 2.2.3.1 | Enabled | Not supported | We recommend that you use the enterprise console. If you must use the open source console, set a whitelist to restrict access. Without a whitelist, the console URL is publicly accessible. |
| 2.x version 2.2.3.1 and later | Disabled | Not supported | We recommend that you use the enterprise console. If you must use the open source console, enable the console, then set a whitelist to restrict access. |
| 3.x | Disabled | Supported | Enable the console, then reset the password before first use. |
For versions that do not support authentication (1.x and 2.x), the console URL is publicly accessible to anyone on the internet. Configure a whitelist to restrict access.
Enable the open source console
To enable the console, set the ConsoleUIEnabled parameter to Yes in the MSE console. This triggers a rolling restart of the Nacos cluster.
Enabling the console restarts the Nacos cluster. Cluster nodes restart sequentially, which may cause a small number of client request failures or reconnections. Perform this operation during off-peak hours.
If RAM authentication is enabled on the instance, the open source console cannot access data in the MSE registry. Use the enterprise console instead.
Log on to the MSE console and select a region in the top navigation bar.
In the left-side navigation pane, choose Microservices Registry > Instances.
On the Instances page, click the name of the target instance.
In the left-side navigation pane, click Parameter Settings.
On the Parameter Settings page, click Edit, set ConsoleUIEnabled to Yes, and then click Save And Restart Instance.
After the restart completes, access the console through the instance's console URL.
Reset the open source console password
Nacos 3.x enables authentication by default. The default username is nacos. Reset the password before first use to secure the console.
Log on to the MSE console and select a region in the top navigation bar.
In the left-side navigation pane, choose Microservices Registry > Instances.
On the Instances page, click the name of the target instance.
On the Basic Information page, click Reset.
In the confirmation dialog box, click Reset.
Copy the generated password and save it in a secure location. Do not click Reset again. Close the dialog box after you save the password.
The password is displayed only once. After you close the dialog box, the password cannot be retrieved. If you lose the password, click Reset again to generate a new one.
