Quickly change Tomcat port to the one you need.

Here we’ll be using label <CATALINA_HOME> to denote the folder where Tomcat is installed. In our systems, tomcat is installed in the following path.
<CATALINA_HOME>=C:\Java\Tomcat_x.x
We need to edit the file named server.xml inside <CATALINA_HOME>\conf folder.
In the server.xml file; locate the following segment.
<!-- Define a non-SSL HTTP/1.1 Connector on port 8080 -->
<Connector port="8080" … />
<Connector port="8081" … />
