[原]升级mpd-0.14 后出现错误的解决办法

修改 /etc/init.d/mpd
sudo mpd --no-daemon --stdout 提示无法正确解析 /var/lib/mpd/state

   --no-daemon        don't detach from console
   --stdout           print messages to stdout and stderr

sudo vim /var/lib/mpd/state

audio_device_state:1:default detected output
state: stop
random: 0
repeat: 0
crossfade: 0
playlist_begin

一是playlist_begin 这行给删了 , 二是在最后一行加上 playlist_end


正确格式为

] $ cat state
audio_device_state:1:default detected output
state: stop
random: 0
repeat: 0
crossfade: 0
playlist_begin
0:music/动力火车/那就这样吧.mp3
1:music/潘多拉/Coboy come form hell.MP3
2:music/潘多拉/bad.mpg
3:music/潘多拉/gates.mp3
4:music/潘多拉/gg.mp3
playlist_end

这时重启mpd

$ sudo /etc/init.d/mpd restart
mpd                     | * Caching service dependencies ...                                                           [ ok ]
mpd                     | * Stopping Music Player Daemon ...
mpd                     |

mpd                     |/etc/init.d/mpd: line 28:   828 已放弃               /usr/bin/mpd --kill /etc/mpd.conf        [ !! ]

解决办法，先sudo vim /etc/init.d/mpd ，在 28行mpd --kill 后面加上一句 echo "stop" ，然后就可以正常的restart 了，这时再把刚加入的 echo "stop" 删了，其实目的是为了能让 $? 值返回成功，表示正确执行stop，但因为之前start时mpd已失败退出，根本就没这个进程，所以kill 要失败
