MPC手机dlan推流音乐到mpd恢复到当前播放记录
现在先别重启
把下面 4 个命令的结果给我：
ps -o pid,ppid,lstart,cmd -p 804
systemctl list-units --type=service --all | grep -Ei 'mpd|autostart'
grep -R "mpd" /etc/systemd/system /etc/rc.local /usr/local/bin 2>/dev/null | head -100
mpc status
killall -9 mpd
sudo -u mpd /usr/bin/mpd /etc/mpd.conf
现在先恢复 MPD，执行这几条
不要重启机器。
systemctl stop mpd-dlna-resume.service 2>/dev/null
systemctl disable mpd-dlna-resume.service 2>/dev/null
kill 804
sleep 2
systemctl reset-failed mpd.service
systemctl start mpd.service
sleep 3
systemctl status mpd --no-pager
mpc status
systemctl restart upmpdcli
mpd.service
↓
MPD :6600
↓
upmpdcli
↓
BubbleUPnP
ss -lntp | grep ':6600'
lsof -nP -iTCP:6600 -sTCP:LISTEN
ps aux | grep '[m]pd'
systemctl status mpd-manager.service --no-pager
马上执行：
systemctl reset-failed mpd.service
systemctl start mpd.service
systemctl status mpd --no-pager
第一步：启动 MPD
执行：
systemctl reset-failed mpd.service
systemctl start mpd.service
sleep 3
systemctl status mpd --no-pager
然后：
mpc status
- 替换 mpd-autostart.sh
直接执行：
cat > /usr/local/bin/mpd-autostart.sh <<'EOF'

# 功能：
#
# 1. 本地播放每5秒保存队列和进度
# 2. DLNA开始时绝不覆盖本地队列
# 3. DLNA结束后直接播放下一首
# 4. 切换过程中临时静音，防止旧歌曲/第一首窜声
# 5. 下一首从0:00开始
# 6. 最后一首自动循环第一首
# 7. 网络流卡死自动检测
# 8. MPD无响应自动重启
# 9. 网络流卡死后自动恢复本地队列
# 10. 恢复过程中禁止保存状态

这个很重要，因为你之前已经产生过：
207 首 101 首 4811 首 1770 首
这些旧快照不能继续使用。
执行：
systemctl stop mpd-dlna-resume.service
