See this page for more details on how to install Apache Tomcat:
https://help.ubuntu.com/lts/serverguide/tomcat.html

Download Apache Tomcat: http://tomcat.apache.org

Extract the file "apache-tomcat-9.0.0.M13.tar.gz" in the folder you want to install Tomcat: /opt/apache-tomcat-9.0.0.M13

$ tar -xf ~/Downloads/apache-tomcat-9.0.0.M13.tar.gz -C /opt/

Change the folder permissions:

$ chmod -R 755 /opt/apache-tomcat-9.0.0.M13/
$ sudo chown -R mtitek:mtitek /opt/apache-tomcat-9.0.0.M13/

Create a symbolic link of the Tomcat installation folder:

$ sudo ln -s /opt/apache-tomcat-9.0.0.M13/ /opt/apache-tomcat
$ sudo chown -R mtitek:mtitek /opt/apache-tomcat

You should replace mtitek:mtitek with your actual user/group names.
