Maven-tomcat plugin bootstrap webapp not working

Created a simple Webapp using maven:

mvn archetype:generate -DgroupId=com.kids -DartifactId=kidsMaven -DarchetypeArtifactId=maven-archetype-webapp -DinteractiveMode=false

My POM file is as follows:

I wanted to run my this bootstrap webapp on tomcat server using maven plugin. When I am executing

mvn tomcat:deploy

I am getting following error:

[ERROR] Failed to execute goal org.codehaus.mojo:tomcat-maven-plugin:1.1:deploy (default-cli) on project kidsMaven: Cannot invoke Tomcat manager: Connection refused: connect -> [Help 1]

I have not installed tomcat externally; instead wants maven to even control my tomcat installation too.

tomcat:deploy pushes webapp to an existing tomcat deployment. You probably want tomcat:run.
