macOS Server 5.4 (for High Sierra) comes with the /usr/sbin/serverinfo command (which was originally introduced in Mountain Lion Server). The serverinfo command is useful when programmatically obtaining information about the very basic state of an Apple Server.
The first option indicates whether the Server app has been downloaded from the app store, which is the –software option:
When used, this option reports the following if the Server.app can be found:
This system has server software installed.
Or if the software cannot be found, the following is indicated:
This system does NOT have server software installed.
The –productname option determines the name of the software app:
If you change the name of the app from Server then the server info command won’t work any longer, so the output should always be the following:
The –shortversion command returns the version of the Server app being used:
The output will not indicate a build number, but instead the version of the app on the computer the command is run on:
To see the build number (which should iterate with each update to the Server app from the Mac App Store, use the –buildversion option:
The output shows the build of server, which doesn’t necessarily match the macOS build number:
Just because the Server app has been downloaded doesn’t mean the Server setup assistant has been run. To see if it has, use the –configured option:
The output indicates whether the system is running as a server or just has the app installed (e.g. if you’re using it to connect to another server:
This system has server software configured.
You can also output all of the information into a single, easy to script against property list using the –plist option:
The output is a list of each of the other options used:
<?xml version=”1.0″ encoding=”UTF-8″?>
<!DOCTYPE plist PUBLIC “-//Apple//DTD PLIST 1.0//EN” “http://www.apple.com/DTDs/PropertyList-1.0.dtd”>
The Server Root can reside in a number of places. To see the path (useful when scripting commands that are relative to the ServerRoot:
By default, the output is as follows, which is basically like a dirname of the ServerRoot:
You can also see whether the system is running on actual hardware desgnated by Apple for servers using the –hardware option:
The output simply indicates if the hardware shipped with OS X Server on it from Apple:
This system is NOT running on server hardware.
The –perfmode option indicates whether or not the performance mode has been enabled, dedicating resources to binaries within the Server app:
If the performance mode has not been enabled then the output will be as such:
Server performance mode is NOT enabled.
Note: Performance mode doesn’t seem to be support any longer, as none of the options will actually enable the service.
