Como vimos en la entrada anterior
La forma de instalar y de configurar este servidor lógico de streaming, ahora en esta entrada vamos a ver como se puede dejar ejecutando como un daemon (si cierran la session del usuario no importa!, UMS seguirá disponible en la LAN para disponibilizar los recursos que querramos.
systemd:
Vamos a crear un usuario quien será el que ejecute el service:
$ sudo useradd -d /usr/local/bin/UMS -s /usr/sbin/nologin ums
$ sudo chown -R ums:ums /usr/local/bin/UMS
$ sudo chown -R ums:ums /usr/local/bin/UMS
Creamos archivo de «service»: /etc/systemd/system/ums.service
[Unit]
Description=Universal Media Server
[Service]
Type=simple
Environment="UMS_PROFILE=/usr/local/bin/UMS/UMS.conf"
User=ums
Group=ums
ExecStart=/usr/local/bin/UMS/UMS.sh
[Install]
WantedBy=multi-user.target
Description=Universal Media Server
[Service]
Type=simple
Environment="UMS_PROFILE=/usr/local/bin/UMS/UMS.conf"
User=ums
Group=ums
ExecStart=/usr/local/bin/UMS/UMS.sh
[Install]
WantedBy=multi-user.target
Ahora vamos a refrescar la conf de Systemd, activar y ejectuar nuestro nuevo service:
$ sudo systemctl daemon-reload
$ sudo systemctl enable ums
$ sudo systemctl start ums
$ sudo systemctl enable ums
$ sudo systemctl start ums
Se puede consultar a SystemD el status del service:
$ sudo systemctl status ums
SystemD captura toda la salida de la ejecución del service y lo guarda en journalctl, al ejecutarlo vamos a ver la salida que obtendríamos al ejecutar
$ journalctl
sysVinit:
script para daemon:
1.- Primero debemos crear un archivo llamado UMS.sh y ubicarlo en /etc/init.d/
2.- en el contenido del archivo vamos a colocar el sig. codigo:
#!/bin/bash

3.- Transportamos la configuración y el archivo de log:
sudo cp -p ~/.config/UMS/UMS.conf /usr/local/bin/UMS/
sudo cp -p ~/.config/UMS/debug.log /usr/local/bin/UMS/
sudo cp -p ~/.config/UMS/debug.log /usr/local/bin/UMS/
4.- Ya podemos lanzar el UMS como un daemon:
sudo service UMS.sh start
Pueden ver el formato de uso simplemente haciendo
sudo service UMS.sh
Enjoy!
Peculiar article, totally what I needed.
