The ambari-server command manages the setup process. Follow the prompts:

ambari-server setup

If you have not temporarily disabled SELinux, you may get a warning. Enter y to continue.
By default, Ambari Server runs under root. If you want to create a different user to run the Ambari Server instead, or to assign a previously created user, select y at Customize user account for ambari-server daemon and give the prompt the username you want to use.
If you have not temporarily disabled iptables you may get a warning. Enter y to continue. See Configuring Ports for (2.x) or (1.x) for more information on the ports that must be open and accessible.
