Node Port

It specifies the listening port on a node.

Value Range

From 20106 to 32767

Default Value

From 30000 to 32767

Modifiable

Yes

Scope

CCE standard and CCE Turbo clusters

Suggestions

Configure the parameter to a range of 30000 to 32767. The value range is determined by the service-node-port-range configuration item of the cluster where the node is running.

If the port is less than 20106, there may be a conflict with the CCE health check port, which can cause the cluster to become unavailable.

If the port is greater than 32767, there may be a conflict with the ports in net.ipv4.ip_local_port_range, which can affect the network performance.
