Installation Tomcat on AWS Environment & Performing continuous Download, Build, Deployment. Importance of Context Path

First update repository sudo apt-get update, After that install Tomcat 

Sudo apt-get install –y tomcat8 , after that we need to install one more package Sudo apt-get install –y tomcat8-admin 

Check the tomcat in browser with public ip address with port #8080 

Goto cd/etc/tomcat8/, we need to create one user in tomcat8 for that we need to modify the tomcat-user.xml file sudo vim tomcat-user.xml  

<user username=”training”password=”sunilsunil” roles=”manager-script,manager-status,manager-gui”/ > 

After that we need to restart the tomcat8 sudo service tomcat8 restart 

Similarly, we need to install tomcat8 in Production instance 

After that we edit file of tomcat8 

<user username=”learning”password=”sunilsunil” roles=”manager-script,manager-status,manager-gui”/ >
