title: node.js in production environment
body: <p>I have to set-up node environment in my production system. I installed node in my local system its fine, after that i checked for version <code>node -v</code>.</p>
  
  <p>Now i installed node in my production system using <code>sudo apt get install nodejs</code> and now i checked the version <code>node -v</code> nothing happened but i used <code>nodejs -v</code>, its working.  </p>
  
  <p>Also in my local system i used <code>node filename.js</code> to run my node app. But in my production system i have to use <code>nodejs filename.js</code>. I dont know why this happening? Also whether it will create problem in my production. Please share your ideas.</p>
