title: Change Jenkins port on macOS
body: <p>I was wondering how one could change Jenkins' default port 8080. Using linux or windows, this is simply done with the configuration file. But the Mac config file of Jenkins looks completely different from the other ones.</p>
  
  <p>Of course one could pass the --httpPort parameter when starting the server, but I want to do this within a config file.</p>
  
  <p>Is there an option for that?</p>
  
  <p>PS: Passing the Jenkins instance through apache would kinda solve the problem, but I want to change the Jenkins port.</p>
  
  <p>Thanks!</p>
