Common Ports of Components
Scenario
When you buy a custom cluster of an LTS version, you can customize the component port. If you do not want to customize a port, an open source port is used.
- Open source: Find the default port of the component in the Default Open Source Port column of the following table.
- Custom: Find the default port of the component in the Default Custom Port column of the following table.
- If there is only the Default Port column, the open source port of the component is the same as the default custom port.
If the cluster is not of an LTS version, the Component Port parameter is unavailable and only an open source port can be used. For details, see the Default Open Source Port or Default Port column.
