The following story is not pretty. I am hoping there is an easier way in the future. Until then, here is how I installed a music server on a Mac.
We have a Mac Mini that is used to hold the family's music collection. However, since this machine is also used by the kids for homework, iTunes is not always running. I finally got around to installing a DAAP server on the machine so I could expect to find the music available when I wanted it. I used brew to build and install the mt-daapd server. Assuming you have brew installed you need only run
brew install mt-daapd
However, for some reason the brew recipe did not complete the installation. This turned out to be fortuitous as I continue to want use iTunes to manage the music located in my home directory. And so I configured mt-daapd to run from within my home directory. First I created the /Users/ajg/Library/Application Support/mt-daapd directory for mt-daapd data. Then created a configuration file at /Users/ajg/Library/Application Support/mt-daapd/mt-daapd.conf containing
mp3_dir /Users/ajg/Music/iTunes/iTunes Media/Music
db_dir /Users/ajg/Library/Application Support/mt-daapd
servername Minimac Fulltime
logfile /Users/ajg/Library/Application Support/mt-daapd/mt-daapd.log
Your configuration should be the same except, perhaps, for port (the default is 3689 which conflicts with iTunes), password, mp3_dir, and servername. To test the installation run the following and then open iTunes so see the "Minimac Fulltime" server.
/usr/local/sbin/mt-daapd -y -c '/Users/ajg/Library/Application Support/mt-daapd/mt-daapd.conf' -f -d 1
Once it is working, the next step is to keep it running using OS X's launchd. Create the file /Users/ajg/Library/Application Support/mt-daapd/mt-daapd.plist containing
<?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">
Install it and start the server running
launchctl load "/Users/ajg/Library/Application Support/mt-daapd/mt-daapd.plist"
launchctl start mt-daapd
I can now listen to music on any of my devices around the house; which includes a first generation iPod Touch using Simple DAAP Client. And if I need to check the server's status I can open http://localhost:3688/.
