Now that we have successfully started the Selenium Grid hub, we will need to have a look at how we can start adding Selenium servers to the hub so that it starts forming the grid of computers that we are expecting. You will notice that compared to Selenium Grid for Selenium 1, we won't have to add a new server for each browser that we want to use. The server has always been able to handle more than one browser and because of architectural changes, we can now start one server and have it control all the browsers installed on that machine.

We will pass in two required arguments: that the server we are starting is a node, and the location of the hub. The Selenium Server will try and use the 5555 port. If this is...
