如何安裝羅技媒體伺服器（Squeezebox Server）？

Question 1

在撰寫本文時最新版本是 7.9.2。

可用這裡。您可以找到其他幾個版本的概述這裡。link根據您的系統將其複製到剪貼簿中的檔案。

使用 .zip 檔案將檔案下載到您的系統wget link。安裝file與sudo dpkg -i file.這會安裝失敗由於缺少依賴項。

用修復它sudo apt -f install。

從開始sudo service logitechmediaserver start。

檢查是否與一起運作top。

透過 Web-GUI 連接到伺服器（位於）http://IPofYOURserver:9000。

設定都在/var/lib/squeezeboxserver/prefs/server.prefs.

這包括媒體庫的目錄，還包括本地客戶端的設置，例如舊 Squeezebox Boom 顯示器中顯示的資訊大小。

如果您想避免設定所有新內容，您可以覆蓋server.prefs.為了能夠做到這一點，你必須這樣做sudo systemctl stop logitechmediaserver。

然後複製該文件並sudo chown squeezeboxserver:nogroup /var/lib/squeezeboxserver/prefs/server.prefs.

最後，sudo systemctl start logitechmediaserver。

更新：也許需要將用戶squeezeboxserver新增到群組中users。此外，播放清單的位置應該是chmod 775。

如果你使用防火牆之類的ufw處理連接埠已解釋這裡。

Question 2

我升級到 Ubuntu 20.04，這破壞了我的安裝，但我想出瞭如何讓它再次工作：

經過一番磨練後，我考慮重新安裝。所以我刪除了 /var/lib/squeezeboxserver/ 中的舊內容

然後我從以下位置獲得了 8.0（測試版）版本的新 deb 資料包：http://downloads.slimdevices.com/nightly/?ver=8.0

就我個人而言，我使用了最平台的版本，但根據平台，只需選擇一個合適的 deb：

wget http://downloads.slimdevices.com/nightly/8.0/lms/cf7bcdb87b4f8bf6f71f5b5444c923afae4c300d/logitechmediaserver_8.0.0~1589180193_all.deb

安裝它： dpkg -i logitechmediaserver_8.0.0_1588799628_all.deb

當我也嘗試過舊版本，甚至嘗試過 git checkout 時，我希望我不缺少任何細節，另一個腳本已經為我完成了，而沒有註意到它。

如果 dpkg 安裝尚未新增使用者和群組，請執行以下操作：

adduser squeezeboxserver
usermod -a -G squeezeboxserver squeezeboxserver

為pid檔案建立一個目錄：

mkdir /var/run/logitechmediaserver

並將其提供給該使用者和群組：

chown squeezeboxserver:squeezeboxserver /var/run/logitechmediaserver

/var/lib/squeezeboxserver/ 中的內容也是如此

chown squeezeboxserver:squeezeboxserver /var/lib/squeezeboxserver
chown -R squeezeboxserver:squeezeboxserver /var/lib/squeezeboxserver/*

問題出在 /etc/init.d 中的啟動腳本。它根本不起作用，因為 Ubuntu 20.04 不再有啟動-停止-守護程式。它只是連結到 /bin/true ，這可能適用於某些腳本，但不適用於 logitechmediaserver。我嘗試了這個程序的 C 實現，但它有它的鉸鏈，所以我放棄了啟動-停止-守護程序並相應地修改了啟動程序。

只需將舊的啟動腳本儲存起來（只是為了保存）並將此內容複製到您選擇的編輯器中：

### 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.

是的，它並不漂亮，但它對我來說很有效，希望對你也有幫助。您必須將其放在 /etc/init.d 中，名稱為 logitechmediaserver

之後，您必須執行以下命令以使 systemctl 滿意：

systemctl daemon-reload

只需啟動它即可進行測試運行：

/etc/init.d/logitechmediaserver start

您應該能夠使用網頁瀏覽器登入http://你的伺服器IP:9000/並配置它。

並測試它是否再次關閉：

/etc/init.d/logitechmediaserver stop

一切順利後，啟用該服務：

systemctl enable logitechmediaserver.service
