                              Step 5: Setup User&Admin Accounts


 For security reasons, no users or passwords are created for the Tomcat manager roles by default. In a production deployment,
  it is always best to remove the Manager application.

To set roles, user name(s) and password(s), we need to configure the tomcat-users.xml file located at $CATALINA_HOME/conf/tomcat-users.xml.

In the case of our installation, $CATALINA_HOME is located at /opt/apache-tomcat-8.0.0-RC1

Edit /opt/apache-tomcat-8.0.0-RC1/conf/tomcat-users.xml file in your editor and modify inside <tomcat-users> </tomcat-users> tags.



<tomcat-users>

  <role rolename="tomcat"/>
  <role rolename="role1"/>
  <user username="tomcat" password="tomcat" roles="tomcat"/>
  <user username="both" password="tomcat" roles="tomcat,role1"/>
  <user username="role1" password="tomcat" roles="role1"/>

</tomcat-users>
