title: Just installed nginx and now having bind error - address already in use
body: <p>i am running a vps with apache. 
  just installed nginx. got the address already in use error at port 80 because apache is using it. I am new to linux/apache stuff so is it possible to change the port of nginx and how ? if yes will it work as i want it to serve static files automaticaly or should i get my hosting company to do it instead since i don't know much about these.</p>
  
  <p>and yes i used this tutorial to install it <a href="http://library.linode.com/web-servers/nginx/installation/centos-5" rel="nofollow">http://library.linode.com/web-servers/nginx/installation/centos-5</a></p>
  
  <p>Help Appreciated :) </p>
  
  <p>Thanks in advance</p>
