1. Run the command spex cluster scale --name <cluster-name> --host <host-ip> to scale out a cluster. Example: in demo cluster, scale out the ShardingSphere-Proxy whose IP address is 10.0.1.2.

$ spex cluster scale --name demo --host 10.0.1.2

2. Run the command spex cluster install -n demo --type proxy --host 10.0.1.2 to add a new node.

[root@community /]# spex cluster install -n demo --type proxy --host 10.0.1.2
