If your Airtime server is not working as expected, individual components of the system can be started, stopped, restarted or checked in the server console using the invoke-rc.d command:
sudo invoke-rc.d airtime-liquidsoap start|stop|restart|status sudo invoke-rc.d airtime-playout start|stop|restart|status sudo invoke-rc.d airtime-media-monitor start|stop|restart|status sudo invoke-rc.d apache2 start|stop|restart|status sudo invoke-rc.d rabbitmq-server start|stop|restart|status
For example, to restart the Airtime playout engine, you could enter the command:
sudo invoke-rc.d airtime-playout restart
The server should respond:
Restarting Airtime Playout: Done.
The status option for airtime-playout and airtime-media-monitor runs the airtime-check-system script to confirm that all of Airtime's dependencies are installed and running correctly.
Airtime stores log files under the directory path /var/log/airtime/ which can be useful for diagnosing the cause of any problems. Copies of these log files may be requested by Sourcefabric engineers while they are providing technical support for your Airtime deployment. See the chapter The airtime-log command for more details.
Liquidsoap output can be tested using two commands provided by Airtime. The airtime-test-soundcard command enables you to send a test tone to the default sound card on the system, so you can check that your audio equipment is working. Press Ctrl+C on your keyboard to stop the tone.
airtime-test-soundcard [-v]
[-o alsa | ao | oss | portaudio | pulseaudio ]
[-h]
Where:
-v verbose mode
-o Linux Sound API (default: alsa)
-h show help menu
The airtime-test-stream command enables you to send a test tone to a local or remote streaming media server. Press Ctrl+C on your keyboard to stop the tone being streamed.
airtime-test-stream [-v]
[-o icecast | shoutcast ] [-H hostname] [-P port]
[-u username] [-p password] [-m mount]
[-h]
Where:
-v verbose mode
-o stream server type (default: icecast)
-H hostname (default: localhost)
-P port (default: 8000)
-u user (default: source)
-p password (default: hackme)
-m mount (default: test)
-h show help menu
If the Airtime logs indicate failures to connect to the RabbitMQ server, such as:
2013-10-31 08:21:11,255 ERROR - [pypomessagehandler.py : main() : line 99] - Error connecting to RabbitMQ Server. Trying again in few seconds
but the RabbitMQ server is running normally, this error might be due to a change in the server's hostname since Airtime installation. Directory names under /var/lib/rabbitmq/mnesia/ indicate that RabbitMQ's database files are organised according to the hostname of the server, for example:
rabbit@airtime
where the hostname is airtime.example.com. If the hostname has changed, it may be necessary to reconfigure RabbitMQ manually, as follows:
1. Delete the files in /var/lib/rabbitmq/mnesia/
sudo rm -r /var/lib/rabbitmq/mnesia/*
2. Restart RabbitMQ:
sudo invoke-rc.d rabbitmq-server restart
3. Enter the following commands to set up authentication and grant permissions. The rabbitmqctl add_user command requires the RabbitMQ password from the /etc/airtime/airtime.conf file as an argument. The rabbitmqctl set_permissions command should be entered on one line, with the list of Airtime services repeated three times:
rabbitmqctl add_vhost /airtime
rabbitmqctl add_user airtime XXXXXXXXXXXXXXXXXXXX
rabbitmqctl set_permissions -p /airtime airtime
"airtime-pypo|pypo-fetch|airtime-media-monitor|media-monitor"
"airtime-pypo|pypo-fetch|airtime-media-monitor|media-monitor"
"airtime-pypo|pypo-fetch|airtime-media-monitor|media-monitor"
There has been error in communication with Booktype server. Not sure right now where is the problem.
