我目前在Ubuntu 14.4上运行Liquidsoap,流媒体到Icecast,托管在同一个盒子上。
我的设置运行正常,但是当运行sudo服务liquidsoap重启时,我得到以下错误:
fatal error exception unix.unix_error(50, "bind", "" )
为了重新启动液体肥皂,我需要杀死进程或重新启动。
然后正常运行。直到我出于某种原因需要重新启动。
作为旁注,liquidsoap创建了一个名为liquidsoap的用户和组,但是我通过我创建的另一个用户运行sudo命令。
有人有什么想法吗?
通过启用pid文件创建修复。

上述解决方案都没有解决我的问题。我最近不得不通过在启动守护进程后设置适当的所有权和权限来修复它。在终止进程并重新启动后,进一步的重新启动可以正常工作。
start-stop-daemon --start --quiet --pidfile $rundir/${liq%.liq}.pid
--chuid $user:$group --exec $liquidsoap -- -d $confdir/$liq && sleep 1 && chmod 600 $rundir/${liq%.liq}.pid && chown root:root $rundir/${liq%.liq}.pid
