When you run multiple WSO2 products, multiple instances of the same product, or multiple WSO2 product clusters on the same server or virtual machines (VMs), you must change their default ports with an offset value to avoid port conflicts. Port offset defines the number by which all ports defined in the runtime such as the HTTP/S ports will be changed. For example, if the default HTTP port is 9763 and the port offset is 1, the effective HTTP port will change to 9764. For each additional WSO2 product instance, you set the port offset to a unique value.
Default Ports:
The list of default ports used by all WSO2 products, including WSO2 AS, is given in the administration guide of the WSO2 Carbon platform.
Setting port offset for the server
The default port offset value is 0. There are two ways to set an offset to a port:
- Pass the port offset to the server during startup. The following command starts the server with the default port incremented by 3
:./wso2server.sh -DportOffset=3 - Set the Ports section of
<PRODUCT_HOME>/repository/conf/carbon.xmlas follows:<Offset>3</Offset>
When you set the server-level port offset in WSO2 AS as shown above, all the ports used by the server will change automatically. However, this may not be the case with some WSO2 products. See the documentation for the respective products for information on how the server-level port offset affects other ports in the server.
