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 .
- 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.

deployed.

- If you want the system to automatically refresh the
certificate, select the checkbox of Automatically

DNS provider in the DNS Provider
drop-down list.Note:
