1 DisOrder
2 ========
3
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.
9
10 See CHANGES for details of recent changes to DisOrder.
11
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:
14
15 Build dependencies:
16 Name Tested Notes
17 libdb 4.3.29 4.2 and earlier won't work
18 libgc 6.8
19 libvorbisfile 1.1.2
20 libpcre 6.7 need UTF-8 support
21 libmad 0.15.1b
22 libgcrypt 1.2.3
23 libao 0.8.6
24 libasound 1.0.13
25 libFLAC 1.1.2
26 GNU C 4.1.2
27 GNU Make 3.81
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)
31
32 "Tested" means I've built against that version; earlier or later versions will
33 often work too.
34
35 Runtime dependencies:
36 * Web server:
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)
40
41 Development dependencies (only developers will need these):
42 Automake 1.10 AM_PATH_PYTHON not good enough in 1.7
43 Autoconf 2.61
44 Libtool 1.5.22 1.4 not good enough
45 Bazaar (bzr)
46
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 \
51 libflac-dev

60 Installation
61 ============
62
63 "This place'd be a paradise tomorrow, if every department had a supervisor
64 with a machine-gun"
65
66 NOTE: If you are upgrading from an earlier version, see README.upgrades.
67
68 1. Build the software. Do something like this:
69
70 ./configure --sysconfdir=/etc --localstatedir=/var
71 make
72
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.
76
77 If you only want to build a subset of DisOrder, specify one or more of the
78 following options:
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
82
83 See README.client for setting up a standalone client (or read the
84 disobedience man page).
85
86 The server is only built by default under Linux. See README.mac concerning
87 its use under OS X.
88
89 2. Install it. Most of the installation is done via the install target:
90
91 make installdirs install
92
93 The CGI interface has to be installed separately:
94
95 install -m 755 clients/disorder.cgi /usr/local/lib/cgi-bin/disorder
96
97 3. Create a 'jukebox' user and group, with the jukebox group being the default
98 group of the jukebox user. The server will run as this user and group.
99 Check that this user can read your music files and write to the audio
100 device, e.g. by playing a track. The exact name doesn't matter, it could be
101 'jukebox' or 'disorder' or 'fred' or whatever.
102
103 Do not use a general-purpose user or group, you must create ones
104 specifically for DisOrder.
105
106 4. Create /etc/disorder/config. Start from examples/config.sample and adapt it
107 to your own requirements. In particular, you should:
108 * add 'player' commands for any file formats not supported natively
109 * edit the 'collection' command to identify the location(s) of your own
110 digital audio files. These commands also specify the encoding of
111 filenames, which you should be sure to get right as recovery from an
112 error here can be painful (see BUGS).
113 * edit the 'scratch' commands to supply scratch sounds (or delete them if
114 you don't want any).
115 * edit the 'trust' command to reflect the user the web interface will
116 eventually run as.
117 * edit the 'url' command to give the URL of the web interface.
118 * add or remove 'stopword' entries as necessary (these words won't take
119 part in track name searches from the web interface).
120
121 See disorder_config(5) for more details.
122
123 See README.raw for details on setting up "raw format" players, which allow
124 for pausing and gapless play.
125
126 5. Create /etc/disorder/config.private. This should be readable only by the
127 jukebox group:
128
129 touch /etc/disorder/config.private
130 chown root:jukebox /etc/disorder/config.private
131 chmod 640 /etc/disorder/config.private
132
133 Set up a username and password for root, for example with line like this:
134
135 allow root somepassword
136
137 Use (for instance) pwgen(1) to create the password. DO NOT use your root
138 password - this is a password to give root access to the server, not to give
139 access to the root login.
140
141 See disorderd(8) and disorder_config(5) for more details.
142
143 6. Make sure the server is started at boot time.
144
145 On many Linux systems, examples/disorder.init should be more or less
146 suitable; install it in /etc/init.d, adapting it as necessary, and make
147 appropriate links from /etc/rc[0-6].d.
148
149 7. Start the server.
150
151 On Linux systems with sysv-style init:
152
153 /etc/init.d/disorder start
154
155 By default disorderd logs to daemon.*; check your syslog.conf to see where
156 this ends up and look for log messages from disorderd there. If it didn't
157 start up correctly there should be an error message. Correct the problem
158 and try again.
159
160 8. After a minute it should start to play something. Try scratching it, as any
161 of the users you set up in step 5:
162
163 disorder scratch
164
165 The track should stop playing, and (if you set any up) a scratch sound play.
166
167 9. Add any other users you want to config.private. Each user's password
168 should be stored in a file in their home directory, ~/.disorder/passwd,
169 which should be readable only by them, and should take the form of a single
170 line:
171
172 password MYPASSWORD
173
174 (root doesn't need this as the client can read it out of config.private
175 when running as root.)
176
177 Note that the server must be reloaded (e.g. by 'disorder reconfigure')
178 when new users are added.
179
180 Alternatively the administrator can create /etc/disorder/config.USERNAME
181 containing the same thing as above. It can either be owned by the user and
182 mode 400, or owned by root and the user's group (if you have per-user
183 groups) and mode 440.
184
185 You can use 'disorder authorize' to automatically pick passwords and
186 create these files.
187
188 10. Optionally source completion.bash from /etc/profile or similar, for
189 example:
190
191 . /usr/local/share/disorder/completion.bash
192
193 This provides completion over disorder command and option names.
194
195
196 Web Interface
197 =============
198
199 "Thought I was a gonner baby, but I'm bullet proof"
200
201 These instructions assumes you are using Apache 1.3.x.
202
203 You need to configure a number of things to make this work:
204
205 1. If you want to have a 'jukebox' virtual host, modify the DNS (or hosts file
206 if you are somehow reading this in the 1980s) accordingly and use a fragment
207 such as this one:
208
209 <VirtualHost HOSTNAME>
210 DocumentRoot /home/jukebox/public_html
211 ServerName jukebox.DOMAIN
212 ServerAlias jukebox
213 ServerAdmin webmaster@DOMAIN
214 ErrorLog /var/log/apache/jukebox/error.log
215 TransferLog /var/log/apache/jukebox/access.log
216 Alias /static/ /usr/local/share/disorder/static/
217 </VirtualHost>
218
219 /static/ should point to the 'static' directory installed by DisOrder. If
220 you don't want to use the name 'static' then you can change the url.static
221 label in the web interface configuration to your preferred URL; see
222 disorder_config(5) for details.
223
224 Don't forget to reload Apache after modifying its configuration.
225
226 Separate logging is not required but I find it convenient. Up to you.
227
228 2. disorder.cgi assumes it is subject to access control (and in particular uses
229 the username to report who did what). Here's how I configured Apache, given
230 the above VirtualHost settings:
231
232 <Directory /home/jukebox>
233 Require valid-user
234 AuthType basic
235 AuthName jukebox
236 AuthUserFile /home/jukebox/http.users
237 </Directory>
238
239 Adjust this according to wherever you're going to install disorder.cgi and
240 its expected URL.
241
242 Don't forget to reload apache after modifying its configuration. If you got
243 it wrong, fix it and restart Apache.
244
245 3. Create the password file configured above. Something like this:
246
247 # htpasswd -b -c /home/jukebox/http.users myusername mypassword
248 Adding password for user myusername
249 # htpasswd -b /home/jukebox/http.users othername otherpass
250 Adding password for user othername
251
252 4. The jukebox must be configured to trust the web user. I added the following
253 line to my /etc/disorder/config:
254
255 trust www-data
256
257 This might not be the same on your system! You have to specify the user
258 that the CGI script runs as, whatever that is.
259
260 5. Install disorder.cgi in an appropriate location. Remember to make it
261 executable. With the above configuration I installed it as
262 ~jukebox/public_html/index.cgi.
263
264 6. Give www-data (or whatever user it is) a password and edit
265 /etc/disorder/config.private accordingly. This file should be mode 640 and
266 owned by root:jukebox. The line should look something like this:
267
268 allow www-data MYPASSWORD
269
270 After editing the config file, you must make the daemon re-read it:
271
272 disorder reconfigure
273
274 7. Teach www-data its password, by putting it in /etc/disorder/config.www-data.
275 This file should be mode 640 and owned by root:www-data.
276
277 password MYPASSWORD
278
279 (You could also use ~www-data/.disorder/passwd for this but on some systems
280 the web server user's home directory is inside the document root, which
281 would have rather unfortunate consequences.)
282
283 8. Try it out. You should be asked for a username and password that you
284 configured earlier, and be shown details of what is playing and what other
285 tracks have been configured for future play.
286
287 9. Some features take time to start working, for instance those involving
288 reporting the length of tracks. This is because the server starts up as
289 quickly as possible even if the full track data has not yet been gathered;
290 the track data is then calculated in the background.
291
292 10. If you run into problems, always look at the appropriate error log; the
293 message you see in your web browser will usually not be sufficient to
294 diagnose the problem all by itself.
295
296 11. If you have a huge number of top level directories, then you might find
297 that the 'Choose' page is unreasonably large. If so add the following line
298 to /etc/disorder/options.user:
299 label sidebar.choosewhich choosealpha
300
301 This will make 'Choose' be a link for each letter of the 26-letter Roman
302 alphabet; follow the link and you just get the directories which start with
303 that letter. The "*" link at the end gives you directories which don't
304 start with a letter.
305
306 You can copy choosealpha.html to /etc/disorder and edit it to change the
307 set of initial choices to anything that can be expressed with regexps. The
308 regexps must be URL-encoded UTF-8 PCRE regexps.
