Starting as a service
The OS X lmadmin installer does not configure the server to start automatically. Check the [install_dir]/examples/service/ directory for a sample startup script
or [install_dir]/examples/launchd/ for a launchd example plist.
For the sample plist file to work, the UserName and GroupName key values need to be changed from
"nobody" to a production UserName and GroupName.
If you use 'lmgrd' instead of 'lmadmin' (and thus don't have the examples/ directory), you can find an example script here
or a launchd plist here
For macOS earlier than 10.13, plist files should be placed in /System/Library/LaunchDaemons rather than in /System/Library/LaunchAgents.
The naming convention for plist files is com.apple.filename.plist.
For macOS 10.13 or later, either location works, and there are no restrictions for plist file naming.
