4 This program is used to play random and chosen tracks from a collection of
5 digital audio files (for instance MP3 and OGG files). If you just set it going
6 it plays random tracks from your collection, but you can also ask for specific
7 tracks to be played, either via a command line program or a web interface, and
8 you can 'scratch' the current track.
10 See CHANGES for details of recent changes to DisOrder.
12 Currently it only runs on Linux. It could probably be ported to other UNIX
13 variants in some cases without too much effort. Things you will need:
17 libdb 4.3.29 4.2 and earlier won't work
20 libpcre 6.7 need UTF-8 support
28 Python 2.4.4 (optional)
29 GTK+ 2.8.20 (if you want the GTK+ client)
30 GLIB 2.12.4 (if you want the GTK+ client)
32 "Tested" means I've built against that version; earlier or later versions will
37 + Apache 1.3.x works for me, but anything that supports CGI and
38 authentication should be suitable.
39 * Separate player programs are no longer required (but may still be used)
41 Development dependencies (only developers will need these):
42 Automake 1.10 AM_PATH_PYTHON not good enough in 1.7
44 Libtool 1.5.22 1.4 not good enough
47 On Debian you might ensure you have the required packages as follows:
48 apt-get install gcc libc-dev automake autoconf libtool libgtk2.0-dev \
49 libgc-dev libgcrypt-dev libpcre3-dev libvorbis-dev \
50 libao-dev libmad0-dev libasound2-dev libdb4.3-dev \

66 NOTE: If you are upgrading from an earlier version, see README.upgrades.
68 1. Build the software. Do something like this:
70 ./configure --sysconfdir=/etc --localstatedir=/var
73 See INSTALL for more details about driving configure. The precise set of
74 options you pass to configure is up to you, if you like configuration being
75 in /usr/local/etc or wherever then that should work.
77 If you only want to build a subset of DisOrder, specify one or more of the
79 --without-server Don't build server or web interface
80 --without-gtk Don't build GTK+ client (Disobedience)
81 --without-python Don't build Python support
83 See README.client for setting up a standalone client.
85 2. Install it. Most of the installation is done via the install target:
87 make installdirs install
89 The CGI interface has to be installed separately, and you must use Libtool
90 to install it. For instance:
92 ./libtool --mode=install install -m 755 progs/disorder.cgi /usr/local/lib/cgi-bin/disorder
94 Depending on how your system is configured you may need to link the disorder
95 libao driver into the right directory:
97 ln -s /usr/local/lib/ao/plugins-2/libdisorder.so /usr/lib/ao/plugins-2/.
99 3. Create a 'jukebox' user and group, with the jukebox group being the default
100 group of the jukebox user. The server will run as this user and group.
101 Check that this user can read your music files and write to the audio
102 device, e.g. by playing a track. The exact name doesn't matter, it could be
103 'jukebox' or 'disorder' or 'fred' or whatever.
105 Do not use a general-purpose user or group, you must create ones
106 specifically for DisOrder.
108 4. Create /etc/disorder/config. Start from examples/config.sample and adapt it
109 to your own requirements. In particular, you should:
110 * add 'player' commands for any file formats not supported natively
111 * edit the 'collection' command to identify the location(s) of your own
112 digital audio files. These commands also specify the encoding of
113 filenames, which you should be sure to get right as recovery from an
114 error here can be painful (see BUGS).
115 * edit the 'scratch' commands to supply scratch sounds (or delete them if
117 * edit the 'trust' command to reflect the user the web interface will
119 * edit the 'url' command to give the URL of the web interface.
120 * add or remove 'stopword' entries as necessary (these words won't take
121 part in track name searches from the web interface).
123 See disorder_config(5) for more details.
125 See README.raw for details on setting up "raw format" players, which allow
126 for pausing and gapless play.
128 5. Create /etc/disorder/config.private. This should be readable only by the
131 touch /etc/disorder/config.private
132 chown root:jukebox /etc/disorder/config.private
133 chmod 640 /etc/disorder/config.private
135 Set up a username and password for root, for example with line like this:
137 allow root somepassword
139 Use (for instance) pwgen(1) to create the password. DO NOT use your root
140 password - this is a password to give root access to the server, not to give
141 access to the root login.
143 See disorderd(8) and disorder_config(5) for more details.
145 6. Make sure the server is started at boot time.
147 On many Linux systems, examples/disorder.init should be more or less
148 suitable; install it in /etc/init.d, adapting it as necessary, and make
149 appropriate links from /etc/rc[0-6].d.
151 For Mac OS X 10.4, a suitable plist file is automatically installed. The
156 ...should show "uk.org.greenend.rjk.disorder" (among other things).
158 If you have a some other init system then you are on your own.
160 7. Make sure the state directory (/var/disorder or /usr/local/var/disorder or
161 as determined by configure) exists and is writable by the jukebox user.
163 mkdir -m 755 /var/disorder
164 chown disorder:root /var/disorder
166 If you want to use some other directory you must put use the 'home' command
167 in the configuration file.
171 On Linux systems with sysv-style init:
173 /etc/init.d/disorder start
177 sudo launchctl start uk.org.greenend.rjk.disorder
179 By default disorderd logs to daemon.*; check your syslog.conf to see where
180 this ends up and look for log messages from disorderd there. If it didn't
181 start up correctly there should be an error message. Correct the problem
184 9. After a minute it should start to play something. Try scratching it, as any
185 of the users you set up in step 5:
189 The track should stop playing, and (if you set any up) a scratch sound play.
191 10. Add any other users you want to config.private. Each user's password
192 should be stored in a file in their home directory, ~/.disorder/passwd,
193 which should be readable only by them, and should take the form of a single
198 (root doesn't need this as the client can read it out of config.private
199 when running as root.)
201 Note that the server must be reloaded (e.g. by 'disorder reconfigure')
202 when new users are added.
204 Alternatively the administrator can create /etc/disorder/config.USERNAME
205 containing the same thing as above. It can either be owned by the user and
206 mode 400, or owned by root and the user's group (if you have per-user
207 groups) and mode 440.
209 You can use 'disorder authorize' to automatically pick passwords and
212 11. Optionally source completion.bash from /etc/profile or similar, for
215 . /usr/local/share/disorder/completion.bash
217 This provides completion over disorder command and option names.
223 "Thought I was a gonner baby, but I'm bullet proof"
225 These instructions assumes you are using Apache 1.3.x.
227 You need to configure a number of things to make this work:
229 1. If you want to have a 'jukebox' virtual host, modify the DNS (or hosts file
230 if you are somehow reading this in the 1980s) accordingly and use a fragment
233 <VirtualHost HOSTNAME>
234 DocumentRoot /home/jukebox/public_html
235 ServerName jukebox.DOMAIN
237 ServerAdmin webmaster@DOMAIN
238 ErrorLog /var/log/apache/jukebox/error.log
239 TransferLog /var/log/apache/jukebox/access.log
240 Alias /static/ /usr/local/share/disorder/static/
243 /static/ should point to the 'static' directory installed by DisOrder. If
244 you don't want to use the name 'static' then you can change the url.static
245 label in the web interface configuration to your preferred URL; see
246 disorder_config(5) for details.
248 Don't forget to reload Apache after modifying its configuration.
250 Separate logging is not required but I find it convenient. Up to you.
252 2. disorder.cgi assumes it is subject to access control (and in particular uses
253 the username to report who did what). Here's how I configured Apache, given
254 the above VirtualHost settings:
256 <Directory /home/jukebox>
260 AuthUserFile /home/jukebox/http.users
263 Adjust this according to wherever you're going to install disorder.cgi and
266 Don't forget to reload apache after modifying its configuration. If you got
267 it wrong, fix it and restart Apache.
269 3. Create the password file configured above. Something like this:
271 # htpasswd -b -c /home/jukebox/http.users myusername mypassword
272 Adding password for user myusername
273 # htpasswd -b /home/jukebox/http.users othername otherpass
274 Adding password for user othername
276 4. The jukebox must be configured to trust the web user. I added the following
277 line to my /etc/disorder/config:
281 This might not be the same on your system! You have to specify the user
282 that the CGI script runs as, whatever that is.
284 5. Install disorder.cgi in an appropriate location. Remember to make it
285 executable. With the above configuration I installed it as
286 ~jukebox/public_html/index.cgi.
288 6. Give www-data (or whatever user it is) a password and edit
289 /etc/disorder/config.private accordingly. This file should be mode 640 and
290 owned by root:jukebox. The line should look something like this:
292 allow www-data MYPASSWORD
294 After editing the config file, you must make the daemon re-read it:
298 7. Teach www-data its password, by putting it in /etc/disorder/config.www-data.
299 This file should be mode 640 and owned by root:www-data.
303 (You could also use ~www-data/.disorder/passwd for this but on some systems
304 the web server user's home directory is inside the document root, which
305 would have rather unfortunate consequences.)
307 8. Try it out. You should be asked for a username and password that you
308 configured earlier, and be shown details of what is playing and what other
309 tracks have been configured for future play.
311 9. Some features take time to start working, for instance those involving
312 reporting the length of tracks. This is because the server starts up as
313 quickly as possible even if the full track data has not yet been gathered;
314 the track data is then calculated in the background.
316 10. If you run into problems, always look at the appropriate error log; the
317 message you see in your web browser will usually not be sufficient to
318 diagnose the problem all by itself.
320 11. If you have a huge number of top level directories, then you might find
321 that the 'Choose' page is unreasonably large. If so add the following line
322 to /etc/disorder/options.user:
323 label sidebar.choosewhich choosealpha
325 This will make 'Choose' be a link for each letter of the 26-letter Roman
326 alphabet; follow the link and you just get the directories which start with
327 that letter. The "*" link at the end gives you directories which don't
330 You can copy choosealpha.html to /etc/disorder and edit it to change the
331 set of initial choices to anything that can be expressed with regexps. The
332 regexps must be URL-encoded UTF-8 PCRE regexps.
