Re: [Savonet-users] liquidsoap: ubuntu upstart script, log reader script
Hi David, Of course you can distribite the scripts, I would feel honored. As far as I understand upstart's exec method, it will fail as soon as the executed command returns. When I use liquidsoap's daemon mode upstart will respawn immediately after starting daemon and give up after 10 attempts in a short time. Maybe upstart offers an alternative mechanism to work with daemon processes, I just don't know. Thanks for answering to active/standby configuration thread, I have learned a lot from it, once again.

[Savonet-users] liquidsoap: ubuntu upstart script, log reader script
Hi, 1) I have written a upstart ( http://upstart.ubuntu.com/ ) script for liquidsoap, because I found none. It can be used to increase availability. If liquidsoap fails, it will immediately be respawned by upstart. You need to check the file paths and log directory. Best check its exec line before setting it live. Then you can place it at /etc/init/liquidsoap.conf. You can start, stop, restart liquidsoap by sudo start liquidsoap sudo stop liquidsoap sudo restart liquidsoap After a few respawns in short time the upstart job will finally fail, so you could use an additional root cronjob to restart in case of failure. * * * * * start liquidsoap For each running liquidsoap service you will have to copy and modify the file. Another limitation is that upstart currently only works with super user acount. Liquidsoap's daemon mode is not used, STD output should be enabled and will be piped to log file. (to see errors directly when starting it manually) Since I am not a upstart expert: If you have any ideas how to improve this, please share it. 2) Another script I want to share is a log merger for syslog, icecast and liquidsoap logs. ./log.pl It merges output of all 3 logs mentioned above in a tail-f manner. It helped me when checking logs of multiple processes on remote machine without GUI. Of cause you can use it for additional/other logs, too: Just change the log paths at the script.
