- Navigate to the CATALINA HOME% conf folder. CATALINA HOME is the location where Tomcat was extracted.
- Open any text editor and look for server.xml.
- In the server.xml file, look for connection port. You’ll find something similar to this below. /> Connector port=”8080″ protocol=”HTTP/1.1″ connectionTimeout=”20000″ redirectPort=”8443″ /> Connector port=”8080″ protocol=”HTTP/1.1″ connectionTimeout=”20000″ connectionTimeout=”20000″ connectionTimeout=”20000
- Set the default port to anything other than 8080. I’m altering it to 9090 in this example. /> Connector port=”8080″ protocol=”HTTP/1.1″ connectionTimeout=”20000″ redirectPort=”8443″ /> Connector port=”8080″ protocol=”HTTP/1.1″ connectionTimeout=”20000″ connectionTimeout=”20000″ connectionTimeout=”20000
