Scaling up the ASE cluster

Scale up the API Security Enforcer (ASE) cluster by adding one node at a time to an active cluster without disrupting traffic.

About this task

To add a new cluster node:

Steps

Enter the peer_node IP address or host name in the cluster.conf file of the ASE node.

Example:

If the IP of the first node is 192.168.20.121 with port 8020, then the peer_node parameter would be 192.168.20.121:8020.

; ASE cluster configuration. These configurations apply only when you have enabled cluster in the api_config file.
; Unique cluster ID for each cluster. All the nodes in the same cluster should have the same cluster ID.
cluster_id=ase_cluster
; Cluster management port.
cluster_manager_port=8020
; Cluster's active nodes. This can be a comma separated list of nodes in ipv4_address:cluster_manager_port format.
peer_node=192.168.20.121:8020

Start the ASE node by changing the working directory to binand running the start.sh script.

Result:

The new node synchronizes configuration and cookie data from the peer nodes. After loading, it becomes part of the cluster.
