Hi there,

You should be able to do that by following these steps

  • Edit the Tomcat server.xml configuration file, the locaiton of the file might depend on the way that you’ve installed Tomcat, but popular locations are at /opt/tomcat/conf/ or /etc/tomcatVERSION
  • After that find the <Connector port="8080" protocol="HTTP/1.1" line, and change the port from 8080 to 80
  • Finally restart Tomcat

Let me know how it goes!

Best,

Bobby

Hello @sergeigerman,

To change default port number, edit the main Connector element in the server.xml file. Find XML tag that looks something like this:

<!-- Define a non-SSL HTTP/1.1 Connector on port 8080 -->
<Connector port="8080" protocol="HTTP/1.1"
           connectionTimeout="20000"
           redirectPort="8443" />

Just change the port attribute from 8080 to 80, and restart Tomcat. Unless that port number is already in use or you lack administrative permission to start a server on port 80, Tomcat should now be operational on port 80.

Let me know how it goes,
