title: Can I Replace Apache with Node.js?
body: <p>I have a website running on CentOS using the usual suspects (Apache, MySQL, and PHP). Since the time this website was originally launched, it has evolved quite a bit and now I'd like to do fancier things with it—namely real-time notifications. From what I've read, Apache handles this poorly. I'm wondering if I can replace just Apache with Node.js (so instead of "<a href="http://en.wikipedia.org/wiki/LAMP_%28software_bundle%29">LAMP</a>" it would "LNMP").</p>
  
  <p>I've tried searching online for a solution, but haven't found one. If I'm correctly interpreting the things that I've read, it seems that most people are saying that Node.js can replace both Apache and PHP together. I have a lot of existing PHP code, though, so I'd prefer to keep it.</p>
  
  <p>In case it's not already obvious, I'm pretty confused and could use some enlightenment. Thanks very much!</p>
