When you run multiple products/clusters or multiple instances of the same product on the same server or virtual machines (VMs), change their default ports with an offset value to avoid port conflicts. An offset defines the number by which all ports in the runtime (e.g., HTTP(S) ports) are increased. For example, if the default HTTP port is 9763 and the offset is 1, the effective HTTP port will change to 9764. For each additional product instance, set the port offset to a unique value. The offset of the default ports is zero. The port value will automatically increase as shown in the Port Value column in the following table, allowing all five WSO2 product instances or servers to run on the same machine. WSO2 product instance | Port Offset | Port Value | WSO2 server 1 | 0 | 9443 | WSO2 server 2 | 1 | 9444 | WSO2 server 3 | 2 | 9445 | WSO2 server 4 | 3 | 9446 | WSO2 server 5 | 4 | 9447 |
