Once the server’s name and IP address are properly configured and the server isn’t going to go to sleep at just the moment when you need to transfer that one big file for the day, it’s time to install the server software. To do so, open the App Store and search for Lion Server. Click on OS X Lion Server and purchase the app.

Once the Server app is installed, it will appear in the Dock. The next step is to install the components. To do so, open the Server app from the Applications folder. When opened for the first time, Server prompts you to install the components. Click on Install to complete the OS X Server installation.

Once the components are installed, install the Server Admin tools, available on the Apple website at http://support.apple.com/kb/DL1457. The tools will download as a standard Apple package. Run the installer, selecting the default options until the package installation is complete.
