Beware, here be dragons!
These Airtime instructions are outdated, see install.md for LibreTime instructions.
You do not normally need to install Airtime manually, unless you are testing a development version of the software. Versions of Airtime recommended for production use are available for download and upgrade via secure apt, as shown in the Automated installation chapter.
Dependencies provided by Sourcefabric
The http://apt.sourcefabric.org/ repository contains up-to-date Debian and Ubuntu packages of Airtime dependencies such as liquidsoap and silan which you may find convenient to install, even if you are installing Airtime manually. Refer to the chapter Automated installation for repository setup details.
Airtime requires a version of python-virtualenv later than 1.4.8, but Ubuntu Lucid includes the older version 1.4.5 of this package. Before performing a manual installation on Lucid, you should update python-virtualenv using the backported package available from the http://apt.sourcefabric.org/ repository. This step is not necessary when performing an automated installation, in which dependencies are resolved automatically.
The airtime-full-install script is designed to configure your server for you, using typical default settings.
In the server terminal or console, download Airtime from https://github.com/sourcefabric/Airtime/releases with wget. For example, to download version 2.5.1, you could use the command:
Then unzip the downloaded file in your home directory. This action will create a subdirectory called airtime-2.5.1:
tar -xvzf airtime-2.5.1-ga.tar.gz -C ~/
Alternatively, clone the git repository if you wish to work on the latest Airtime source code:
git clone https://github.com/sourcefabric/Airtime.git
In order to return your code improvements to Airtime, you will need to create your own fork of the Airtime git repository and send pull requests. See the GitHub help page https://help.github.com/articles/fork-a-repo for details.
Run the airtime-full-install script, for example on Ubuntu:
The installation script will indicate which files are being installed on your system, and the directories they are being unpacked into. Finally, it will run the airtime-check-system script to confirm that your server environment is set up correctly.

You are now ready to proceed to the Configuration chapter.
The alternative airtime-install script does not attempt to configure your server, an option which you may find more suitable if you have special requirements.
In the server terminal or console, install the list of dependencies. For example, on Ubuntu you could enter the command:
sudo apt-get install postgresql python-virtualenv apache2 coreutils \ curl ecasound flac gzip libapache2-mod-php5 libcamomile-ocaml-data \ liquidsoap locales lsof monit mp3gain multitail patch php5-cli \ php5-curl php5-gd php5-json php5-pgsql php-apc php-pear pwgen \ python rabbitmq-server silan sudo sysv-rc tar unzip \ vorbisgain vorbis-tools libzend-framework-php
On Debian, install zendframework instead of the libzend-framework-php package.
Check that the Apache web server modules that Airtime requires are enabled:
sudo a2enmod php5 rewrite
The server should respond:
Module php5 already enabled Module rewrite already enabled
Create a directory to contain the Airtime web interface:
sudo mkdir -p /usr/share/airtime/public
Next, create the Airtime virtual host configuration file for Apache:
sudo nano /etc/apache2/sites-available/airtime.conf
and enter the information below, substituting your server's hostname for airtime.example.com and your system administrator's email address for firstname.lastname@example.org. Make sure you set the DocumentRoot and Directory paths correctly. This should normally match the public directory that the installer will unpack the web interface into, which by default is the /usr/share/airtime/public/ directory. From Airtime 2.3.0 onwards, the web interface can be installed in a subdirectory of the DocumentRoot if you require it to be.
For Apache 2.2, you can use the following syntax:
<VirtualHost *:80> ServerName airtime.example.com ServerAdmin email@example.com DocumentRoot /usr/share/airtime/public php_admin_value upload_tmp_dir /tmp <Directory /usr/share/airtime/public> DirectoryIndex index.php AllowOverride all Order allow,deny Allow from all </Directory> </VirtualHost>
Apache 2.4 uses a different access control syntax in the Directory stanza:
<VirtualHost *:80> ServerName airtime.example.com ServerAdmin firstname.lastname@example.org DocumentRoot /usr/share/airtime/public php_admin_value upload_tmp_dir /tmp <Directory /usr/share/airtime/public> DirectoryIndex index.php AllowOverride all Require all granted </Directory> </VirtualHost>
Press Ctrl+O to save the file, then Ctrl+X to exit the nano editor.
Create the PHP configuration file /etc/airtime/airtime.ini in nano:
sudo nano /etc/airtime/airtime.ini
with the following contents:
[PHP] memory_limit = 512M magic_quotes_gpc = Off file_uploads = On upload_tmp_dir = /tmp apc.write_lock = 1 apc.slam_defense = 0
Save and exit nano, then link this file to the system's PHP configuration with the command:
sudo ln -s /etc/airtime/airtime.ini /etc/php5/conf.d/airtime.ini
Enable the new configuration by entering the command:
sudo a2ensite airtime
The server should respond:
Enabling site airtime. Run '/etc/init.d/apache2 reload' to activate new configuration!
You may also need to disable the default site configuration, which may otherwise interfere with your Airtime installation:
sudo a2dissite default
As suggested by the output of the command above, reload the web server configuration.
sudo /etc/init.d/apache2 reload
The server should respond:
* Reloading web server config apache2
Download Airtime from https://github.com/sourcefabric/Airtime/releases with wget, and unzip the downloaded file in your home directory. This action will create a subdirectory called airtime-2.5.1:
wget https://github.com/sourcefabric/Airtime/archive/airtime-2.5.1-ga.tar.gz tar -xvzf airtime-2.5.1-ga.tar.gz -C ~/
Alternatively, clone the Airtime git repository as shown above.
Monit is a utility which Airtime uses to make sure that the system runs smoothly. Enable it by opening the /etc/default/monit file in the nano editor:
sudo nano /etc/default/monit
Find the line that begins with START and change the value to yes:
Save the file with Ctrl+O and close nano with Ctrl+X. Now copy the Monit configuration from the Airtime install directory to the /etc/monit/conf.d/ directory:
sudo cp ~/airtime-2.5.1/python_apps/monit/airtime-monit.cfg /etc/monit/conf.d/
Open the /etc/monit/monitrc file in nano:
sudo nano /etc/monit/monitrc
At the end of the file, add the line:
Save the file with Ctrl+O and close nano with Ctrl+X. Then start Monit with:
sudo invoke-rc.d monit start
More information about monit is available in the chapter Using Monit.
On Debian squeeze, make sure the rabbitmq-server daemon has started:
sudo invoke-rc.d rabbitmq-server start
Finally, run the minimal airtime-install script:
Once the airtime-check-system script confirms that the install has been successful, you should now be able to log in to the Airtime administration interface, as shown in the Getting started chapter, with the username admin and the password admin. See the Configuration chapter for advanced settings.
Install script options
By default, the airtime-install script preserves any existing configuration or installation that it finds on the server. However, it is also possible to dictate the behaviour of the script with a command line option, as follows:
--help|-h Displays usage information. --overwrite|-o Overwrite any existing config files. --preserve|-p Keep any existing config files. --no-db|-n Turn off database install. --reinstall|-r Force a fresh install of this Airtime version.
To manually uninstall Airtime from the server, run the airtime-uninstall script from the minimal installation directory, for example:
Optionally, you can also delete the Airtime storage and configuration folders, if you have backups and are not going to need the data on this particular server again. The rm command should be used with caution, because it has no undo feature.
sudo rm -r /srv/airtime sudo rm -r /etc/airtime
