Kde mohu získat nejnovější instalační soubory pro server Logitech Media Server a jak je správně nainstalovat?
(Provozuji ho na Raspberry Pi 2 a musel jsem ho několikrát přeinstalovat kvůli vadné SD kartě. Na tuto otázku tedy odpovím převážně jako připomínku pro sebe.)
Přijatá odpověď:
Upgradoval jsem na Ubuntu 20.04 a to přerušilo moji instalaci, ale přišel jsem na to, jak to znovu zprovoznit:
Po nějakém temperování jsem uvažoval o nové instalaci. Takže jsem smazal staré věci ve /var/lib/squeezeboxserver/
Pak jsem dostal nový deb-packet pro verzi 8.0 (beta) z:http://downloads.slimdevices.com/nightly/?ver=8.0
Osobně jsem použil nejplatformnější verzi, ale v závislosti na platformě stačí vybrat vhodný deb:
wget http://downloads.slimdevices.com/nightly/8.0/lms/cf7bcdb87b4f8bf6f71f5b5444c923afae4c300d/logitechmediaserver_8.0.0~1589180193_all.deb
Instalováno pomocí:
dpkg -i logitechmediaserver_8.0.0_1588799628_all.deb
Protože jsem zkoušel i starší verze a dokonce jsem zkoušel i git checkout, doufám, že mi nechybí žádné podrobnosti, které pro mě již udělal jiný skript, aniž bych si toho všiml.
Pokud instalace dpkg ještě nepřidala uživatele a skupinu, udělejte tak:
adduser squeezeboxserver
usermod -a -G squeezeboxserver squeezeboxserver
Vytvořte adresář pro soubor pid:
mkdir /var/run/logitechmediaserver
A dejte to tomuto uživateli a skupině:
chown squeezeboxserver:squeezeboxserver /var/run/logitechmediaserver
Totéž platí pro věci v /var/lib/squeezeboxserver/
chown squeezeboxserver:squeezeboxserver /var/lib/squeezeboxserver
chown -R squeezeboxserver:squeezeboxserver /var/lib/squeezeboxserver/*
Problém přichází se spouštěcím skriptem v /etc/init.d. Jednoduše to nefunguje, protože Ubuntu 20.04 již nemá start-stop-démona. Je jednoduše propojen s /bin/true, což může fungovat pro některé skripty, ale nefunguje pro logitechmediaserver. Zkoušel jsem implementaci C pro tento program, ale měl to panty, takže jsem vypustil start-stop-démona a upravil spouštěcí program podle toho.
Stačí uložit starý spouštěcí skript pryč (jen pro uložení) a zkopírovat tento obsah do libovolného editoru:

### About logitechmediaserver
# The logitechmediaserver is kind of special. It uses the
# squeezeboxserver_safe script, to restart any died squeezeboxserver. This
# can easily happen, for example if you use a MySQL server. Depending on unix
# flavour you are running they sometimes do a regular restart. That would
# cause the squeezeboxserver to terminate. Because of that the
# squeezeboxserver_safe starts a logitechmediaserver every few seconds, which
# gets shut down again if any other logitechmediaserver is still running.
#
# Sadly this procedure messes up, the process id file. You would get a new id
# file, every time a new server process gets started. That process will
# terminate but the process id of the first server process is lost. So the
# killing the squeezeboxserver have to be done with analysing the process
# table.
#
# As I upgraded to Ubuntu 20.04 my logitechmediaserver stopped working.
# Installing the lastest 8.0 version was no problem downloading the deb-packet
# and installing with dpkg. But the server did not start. I could start it
# manually but the startup script was not able to start it. After some looking
# around I found this:
#
# /sbin/start-stop-daemon -> /bin/true
#
# This explains why the start up script is not working. There is no package
# in the ubuntu package repository for the start-stop-daemon.
#
# First I tried the C implementation of start-stop-daemon from Dale O'Brien on
# github (https://github.com/daleobrien/start-stop-daemon). It does not
# implement the --remove-pidfile option the original script. But more
# problematic it threw the error not able to terminate the server while
# doing it without a problem.
#
# I had to compile the C implementation from Dale O'Brien myself, which
# worked without a hitch. Considering the limiations of the implementation
# I came to the conclusion to ditch the start-stop-daemon completly and
# doing it the old school way.

Ano, není to hezké, ale dělá to za mě a doufám, že to pomůže i vám. Musíte jej umístit do /etc/init.d pod názvem logitechmediaserver
Související:Jak přidat možnost vypnutí na obrazovku uzamčení Ubuntu?Poté musíte spustit následující příkaz, aby byl systemctl šťastný:
systemctl daemon-reload
Stačí to vyzkoušet a spustit:
/etc/init.d/logitechmediaserver start
Měli byste být schopni se přihlásit pomocí svého webového prohlížeče na http://YourServerIP:9000/ a nakonfigurovat jej.
A otestujte, zda se znovu vypne:
/etc/init.d/logitechmediaserver stop
Když vše funguje, povolte službu:
systemctl enable logitechmediaserver.service
