title: Re-installing jenkins in Ubuntu
body: <p>Well, I forgot my password for Jenkins and I tried(for one full day) with all usual passwords, failed in all attempts. Hence, I wanted to reinstall jenkins from scratch, luckily I was just setting up and I had no jobs configured yet.</p>
  
  <p>So I removed (rm -Rf) of jenkins folder from tomcat webapps directory, and restarted tomcat. To my surprise Jenkins asks for login again.</p>
  
  <p>What is the proper way to remove and reinstall jenkins? I have jenkins.war and I installed it by just copying it over to tomcat webapps.</p>
  
  <p>Well either - I want to reset my password because I am the only admin or I want to reinstall jenkins from scratch. I have sudo access to the machine, could someone point me on how I can do this?</p>
  
  <p>Jenkins version : 1.530</p>
