Manage Cluster Server Domain Names

This topic describes how to update certificates for cluster server domain names and how to delete the deployed domain names.

Update certificate for cluster server domain name

To avoid service disruption to your cloud PBXs, it is essential to renew the domain name certificate for the cluster servers (SBC Server and SBC Proxy Server) to prevent it from expiring. If you choose to manually upload domain certificates and do not enable certificate auto-refresh, you need to update the certificate in time.
Note: Yeastar Central Management monitors the validity of the domain name certificates. When it comes to 30 days, 15 days and 7 days before the expiration date, or on the day, a Cluster Domain Name Certificate Expired alarm is triggered, and the system proactively sends emails to notify the contacts added in Alarm > Notification Contacts.
Prerequisites
  • Make sure that the Yeastar Central Management version is 87.14.0.31 or later.
  • You have obtained the new domain name certificate, including certificate file and private key.
    Note:
    • Yeastar P-Series Cloud PBX uses NGINX as web server, so the certificate should be compatible with NGINX server.
    • RSA private key and EC private key are supported.
Procedure
  1. Log in to Yeastar Central Management, go to System > Domains > Cluster Domain Name.
  2. Click beside the region where the server is deployed.

    You are redirected to the Edit Cluster Domain Name page.

  3. In the Operations column of the server domain name, click .

  4. In the pop-up window, update the certificate information.

    1. Select Upload certificate.
    2. Click Browse to select the new certificate and private key respectively.
    3. If you want the system to automatically refresh the certificate, select the checkbox of Automatically refresh the certificate, then select your DNS provider in the DNS Provider drop-down list.
      Note:
      • The system will automatically refresh the certificate 7 days before it expires using the provided DNS provider.
      • If auto-refresh is enabled but your certificate is not from Let's Encrypt, the system will automatically apply for a new one from Let's Encrypt instead.
    4. Click Confirm.
  5. Click Save.

Delete cluster server domain names

If you don't need server domain names in a specific region any more, you can delete it right from the Yeastar Central Management web portal.
  1. Log in to Yeastar Central Management, go to System > Domains > Cluster Domain Name.
  2. To delete both SBC and SBC Proxy Server domain names in a region, do as follows:
    Note: Make sure that there is no Cloud PBX using this domain name before you delete it, otherwise the deletion would fail.

    1. Click beside the desired region.
    2. In the pop-up window, click Confirm.
  3. To delete SBC Proxy Server domain name only, do as follows:
    Note:
    • If there is only a single SBC Proxy Server deployed in the region, it is not supported to delete the domain name of the SBC Proxy Server separately.
    • Make sure that there is no Cloud PBX using this domain name before you delete it, otherwise the usage of the Cloud PBX would be affected.

    1. Click beside the region where the server is deployed.
    2. In the SBC Proxy Domain Name section, click beside the SBC Proxy Server.
    3. In the pop-up window, click Confirm.
    4. At the bottom of the page, click Save.
