What is the Configuration Cluster in WHM?
Posted by Allura on 27 12 2018.
The Configuration Cluster interface allows to link a master server to one or more additional servers in the configuration cluster. It can be selected to copy server configuration settings from WHM’s Update Preferences interface (WHM >> Home >> Server Configuration >> Update Preferences ) to the configuration cluster’s servers. As we deprecated WHM’s Remote Access Key feature in cPanel and WHM version 64 and it is recommended to use API tokens instead. Select Send my settings to all configuration cluster servers checkbox in WHMs Update Preferences interface (WHM >> Home >> Server Configuration >> Update Preferences).
Before setting up a configuration cluster in the Configuration Cluster interface, one needs to log in as a root-level user on the server that needs to use as the master server. One must also log in to the master server as a root-level user to make any configuration changes to copy to the configuration cluster’s servers.
The Configuration Cluster interface displays a list of all of the servers that is linked to the currently-authenticated server.
- Server: Server’s IP address, name that is assigned to the server (example.com).
- User: Username of the server’s root-level account. This value is default to the root user.
- Remote Access Key: Signature version of the server’s remote access key or API token.
