The answers given in How to change the port of Tomcat from 8080 to 80? and Tomcat7 bind to port 80 fails in Ubuntu 14.04LTS works good for tomcat7, but as I couldn't do a 'apt-get' to install tomcat8, the files created by default during the installation of tomcat7 at /etc/default/ couldn't be found while installing tomcat8 manually.
Is there any other way to change port form 8080 to 80 after manually installing tomcat8 on Ubuntu 14.04 EC2?
Thanks in advance.
