Almost all of WSO2 products are by default configured to run on port 9443. You will run into many instances where you need to run multiple WSO2 products or multiple instances of the same product in the same environment. In these instances the operating ports of the servers need to be changed.
This can be done mainly in two ways:
Method 1: Setting the port in the carbon.xml
Open the <Product_Home>repository/conf/carbon.xml and change the value between the <Offset> tags. It is by default 0, if you change the value to 2, the server will run on port 9445.
Method 2: Passing the port offset during startup of the server
Running the following command with start the server on port 9445.
In certain rare instances the port has been hard coded instead of being extracted from the carbon.xml. If you receive a “java.net.BindException”, the best possible way is to run the following command to see if it the port value has been hard coded anywhere and then change them accordingly where needed.
grep -ril “9443”
