Configurarea serviciului Svxlink

Configurare serviciu

cd /lib/systemd/system
sudo nano svxlink.service

Mare atenție la parametrii de pornire:

[Service]
EnvironmentFile=/opt/rolink/default/svxlink
PIDFile=${PIDFILE}
ExecStartPre=-/bin/touch ${LOGFILE}
ExecStartPre=-/bin/chown ${RUNASUSER} ${LOGFILE}
ExecStart=/opt/rolink/bin/svxlink --logfile=${LOGFILE} --config=${CFGFILE} --pidfile=${PIDFILE} --runasuser=${$
ExecReload=/bin/kill -s HUP $MAINPID
Restart=on-failure
TimeoutStartSec=60
TimeoutStopSec=10
#WatchdogSec=
#NotifyAccess=main
LimitCORE=infinity
WorkingDirectory=/opt/rolink/svxlink

Mare atenție la configurarea log-ului; serviciul nu poate porni fără o cale către un log valid:

sudo nano /opt/rolink/default/svxlink
#############################################################################
#
# Configuration file for the SvxLink Systemd unit file
#
#############################################################################

# The user to run the SvxLink server as
RUNASUSER=svxlink

# Specify which configuration file to use
CFGFILE=/opt/rolink/svxlink/svxlink.conf

# Where to place the log file
LOGFILE=/opt/rolink/var/log/svxlink.log

# Where to place the PID file
PIDFILE=/run/svxlink.pid

# Disable Alsa zerofill if set to 0 (see manual page)
#ASYNC_AUDIO_ALSA_ZEROFILL=1

Configurarea pentru pornirea automată

După ce au fost parcurși cu success toți pașii de mai sus, se activează pornirea automată a serviciului odată cu pornirea sistemului:

sudo systemctl enable application.service

În cazul în care totul este ok, sistemul răspunde cu:

Created symlink /etc/systemd/system/multi-user.target.wants/svxlink.service → /lib/systemd/system/svxlink.service.

Verificarea cu sudo systemctl status svxlink generează următorul mesaj de succes:
