I’ll go step-by-step on how to create a virtual host in the XAMPP environment. As we know, the default http://localhost points to /opt/lampp/htdocs as the root directory. The desired result is to be able to visit http://examplevhost.local, with the root directory being /opt/lampp/htdocs/examplevhost.

Note: The steps below are done on Ubuntu 16.04, but they should also work on most other Linux distributions (Debian, Mint, Arch).

Note: I’ll assume that XAMPP is installed in /opt/lampp/. If it’s different on your setup, please read carefully and adjust accordingly.

Enable virtual hosts in apache configuration file

Note: This should be done only once per XAMPP installation. If you want to add another virtual host later you can skip to the next step.

var rngstate;
function MathRandom() {
  // Our own implementation of Math.random().
  // Source code was copied from https://github.com/v8/v8/blob/4.6.85/src/math.js#L131
  // You need to solve for the rngstate first before this can be used.
  console.assert(rngstate, "You need to set the global variable `rngstate` first. For example: `rngstate = solve(Math.random(), Math.random());`");
  if (!rngstate) return;
  var r0 = (Math.imul(18030, rngstate[0] & 0xFFFF) + (rngstate[0] >>> 16)) | 0;
  rngstate[0] = r0;
  var r1 = (Math.imul(36969, rngstate[1] & 0xFFFF) + (rngstate[1] >>> 16)) | 0;
