How to change the default port of Tomcat

By default Apache Tomcat consumes 8080 port number of Windows. As an example, I am using Tomcat 8.5 version to change the default port of, but the process of changing the port of Tomcat is the same for all versions. This 8080 port is the default port for other web application servers as well. Often, the organizations do not prefer to go with the default port to avoid conflicts with other applications.

If you want to change Tomcat port, here are the steps.

Steps to change the default port of Tomcat:

1. Go to %CATALINA_HOME%\conf\ folder
   CATALINA_HOME is the folder where you have extracted Tomcat.
2. Look for server.xml and open it in any text editor
3. Search for connector port in the server.xml
   You will find something like below.
   <Connector port="8080" protocol="HTTP/1.1"
               connectionTimeout="20000"
               redirectPort="8443" />
4. Change the default port from 8080 to whatever you want.
   In this example, I am changing it to 9090.
   <Connector port="8080" protocol="HTTP/1.1"
               connectionTimeout="20000"
               redirectPort="8443" />
