Install Plexamp on HiFiBerryOS

gistfile1.txt

Pre-requisits:
My build worked for me and my setup which includes: Raspberry Pi 3b, HiFiBerry DAC+ Standart, wired connection (for some reason connection to plexamp drops on wireless), HiFiBerryOS installed
You need version 9 of nodejs in your system, easiest way in my opinion to install custom version of nodejs and to not affect version 12 that is present in HiFIBerryOS, is to use nvm

1. Ssh to your hifiberry installation

2. Create bash profile file (this is required by nvm)
# touch ~/.profile

3. Install NVM
# curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.36.0/install.sh | bash
This might take several minutes

4. Re-login to you installation to enable NVM CLI

5. Install nodejs version 9
# nvm install 9
After this you should have node version 9 installed in this path:
/root/.nvm/versions/node/v9.11.2/bin/node

6. Download and unpack plexamp
# curl https://files.plexapp.com/elan/Plexamp-v2.0.0-rPi-beta.2.tar.bz2 > plexamp.tar.bz2
# tar -xvf plexamp.tar.bz2

7. Alter plexamp.service file to match actual paths
# nano plexamp/plexamp.service
This is my plexamp service content:
```
[Unit]
Description=Plexamp
After=network.target

[Service]
Environment="PLUGIN_PATH=/root/plexamp/server/node_modules/treble/build/Release/"
Environment="LD_LIBRARY_PATH=/root/plexamp/server/node_modules/treble/build/Release/"
Type=simple
User=root
ExecStart=/root/.nvm/versions/node/v9.11.2/bin/node /root/plexamp/server/server.prod.js
Restart=on-failure

[Install]
WantedBy=multi-user.target
```
8. Now the tricky part
You need to have `server.json` file from real installation of plexamp version < 3. I had to find installation on internet for my mac of Plexamp v.1.1. Then you login in that installation and then find `server.json` file which path depends on your OS.
You need to copy its content and put in a file at this path: `/root/.config/Plexamp/server.json`
Approximate content of this file is:
```
{
  "player": {
    "name": "music-streamer",
    "identifier": "xxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxx"
  },
  "user": {
    "id": 00000,
    "token": "xxxxxxxxxxxxxxxxx"
  },
  "server": {
    "identifier": "xxxxxxxxxxxxxxxxxxxxxxxxxxxx",
    "library": "/library/sections/xx"
  },
  "state": {
    "source": null,
    "state": "stopped",
    "time": 0,
    "volume": 100,
    "playQueueID": null,
    "playQueueItemID": "xxxxx"
  }
}
```
9. Almost there, now you need to install and start plexamp daemon:
# cp plexamp/plexamp.service /lib/systemd/system/plexamp.service
# systemctl daemon-reload
# systemctl enable plexamp
# systemctl start plexamp
# systemctl status plexamp

Last command should display information that service is up and running, now you can try and cast music from your other plexamp or plex app.
