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 4.3.21 4.2 and earlier won't work |
18 | libgc 6.3 |
19 | libvorbisfile 1.0.1 |
20 | libpcre 4.5 need UTF-8 support |
21 | libmad 0.15.1b |
22 | libgcrypt 1.2.0 |
23 | libao 0.8.6 |
24 | libasound 1.0.8 |
25 | Python 2.3 (optional) |
26 | GNU C 3.3, 3.4 |
27 | |
28 | "Tested" means I've built against that version; earlier or later versions will |
29 | often work too. |
30 | |
31 | Runtime dependencies: |
32 | * Players: |
33 | + ogg123 and mpg321 work for me, but you could potentially use others. |
34 | * Web server: |
35 | + Apache 1.3.x works for me, but anything that supports CGI and |
36 | authentication should be suitable. |
37 | |
38 | Development dependencies (only developers will need these): |
39 | Automake 1.9.4 AM_PATH_PYTHON not good enough in 1.7 |
40 | Autoconf 2.59 |
41 | Libtool 1.5.6 1.4 not good enough |
39068fb4 |
42 | Bazaar (bzr) |

44 | On Debian you might ensure you have the required packages as follows: |
45 | apt-get install gcc libc-dev automake autoconf libtool libgtk2.0-dev \ |
46 | libgc-dev libgcrypt-dev libpcre3-dev libvorbis-dev \ |

56 | Installation |
57 | ============ |
58 | |
59 | "This place'd be a paradise tomorrow, if every department had a supervisor |
60 | with a machine-gun" |
61 | |
62 | NOTE: If you are upgrading from an earlier version, see README.upgrades. |
63 | |
64 | 1. Build the software. Do something like this: |
65 | |
66 | ./configure --sysconfdir=/etc --localstatedir=/var |
67 | make |
68 | |
69 | See INSTALL for more details about driving configure. The precise set of |
70 | options you pass to configure is up to you, if you like configuration being |
71 | in /usr/local/etc or wherever then that should work. |
72 | |
73 | If you only want to build a subset of DisOrder, specify one or more of the |
74 | following options: |
75 | --without-server Don't build server or web interface |
76 | --without-gtk Don't build GTK+ client (Disobedience) |
77 | --without-python Don't build Python support |
78 | |
79 | See README.client for setting up a standalone client. |
80 | |
81 | 2. Install it. Most of the installation is done via the install target: |
82 | |
83 | make installdirs install |
84 | |
85 | The CGI interface has to be installed separately, and you must use Libtool |
86 | to install it. For instance: |
87 | |
88 | ./libtool --mode=install install -m 755 progs/disorder.cgi /usr/local/lib/cgi-bin/disorder |
89 | |
90 | Depending on how your system is configured you may need to link the disorder |
91 | libao driver into the right directory: |
92 | |
93 | ln -s /usr/local/lib/ao/plugins-2/libdisorder.so /usr/lib/ao/plugins-2/. |
94 | |
95 | 3. Create a 'jukebox' user and group, with the jukebox group being the default |
96 | group of the jukebox user. The server will run as this user and group. |
97 | Check that this user can read your music files and write to the audio |
98 | device, e.g. by playing a track. The exact name doesn't matter, it could be |
99 | 'jukebox' or 'disorder' or 'fred' or whatever. |
100 | |
101 | Do not use a general-purpose user or group, you must create ones |
102 | specifically for DisOrder. |
103 | |
104 | 4. Create /etc/disorder/config. Start from examples/config.sample and adapt it |
105 | to your own requirements. In particular, you should: |
106 | * edit the 'player' commands to reflect the software you have installed. |
107 | * edit the 'collection' command to identify the location(s) of your own |
108 | digital audio files. These commands also specify the encoding of |
109 | filenames, which you should be sure to get right as recovery from an |
110 | error here can be painful (see BUGS). |
111 | * edit the 'scratch' commands to supply scratch sounds (or delete them if |
112 | you don't want any). |
113 | * edit the 'trust' command to reflect the user the web interface will |
114 | eventually run as. |
115 | * edit the 'url' command to give the URL of the web interface. |
116 | * add or remove 'stopword' entries as necessary (these words won't take |
117 | part in track name searches from the web interface). |
118 | |
119 | See disorder_config(5) for more details. |
120 | |
121 | 5. Create /etc/disorder/config.private. This should be readable only by the |
122 | jukebox group: |
123 | |
124 | touch /etc/disorder/config.private |
125 | chown root:jukebox /etc/disorder/config.private |
126 | chmod 640 /etc/disorder/config.private |
127 | |
128 | Set up a username and password for root, for example with line like this: |
129 | |
130 | allow root somepassword |
131 | |
132 | Use (for instance) pwgen(1) to create the password. DO NOT use your root |
133 | password - this is a password to give root access to the server, not to give |
134 | access to the root login. |
135 | |
136 | See disorderd(8) and disorder_config(5) for more details. |
137 | |
138 | 6. Make sure the server is started at boot time. On many Linux systems, |
139 | examples/disorder.init should be more or less suitable; install it in |
140 | /etc/init.d, adapting it as necessary, and make appropriate links from |
141 | /etc/rc[0-6].d. If you have a BSD style init then you are on your own. |
142 | |
143 | 7. Make sure the state directory (/var/disorder or /usr/local/var/disorder or |
144 | as determined by configure) exists and is writable by the jukebox user. |
145 | |
146 | mkdir -m 755 /var/disorder |
147 | chown disorder:root /var/disorder |
148 | |
149 | 8. Start the server, for instance: |
150 | |
151 | /etc/init.d/disorder start |
152 | |
153 | By default disorderd logs to daemon.*; check your syslog.conf to see where |
154 | this ends up and look for log messages from disorderd there. If it didn't |
155 | start up correctly there should be an error message. Correct the problem |
156 | and try again. |
157 | |
158 | 9. After a minute it should start to play something. Try scratching it, as any |
159 | of the users you set up in step 5: |
160 | |
161 | disorder scratch |
162 | |
163 | The track should stop playing, and (if you set any up) a scratch sound play. |
164 | |
165 | 10. Add any other users you want to config.private. Each user's password |
166 | should be stored in a file in their home directory, ~/.disorder/passwd, |
167 | which should be readable only by them, and should take the form of a single |
168 | line: |
169 | |
170 | password MYPASSWORD |
171 | |
172 | (root doesn't need this as the client can read it out of config.private |
173 | when running as root.) |
174 | |
175 | Note that the server must be reloaded (e.g. by 'disorder reconfigure') |
176 | when new users are added. |
177 | |
178 | Alternatively the administrator can create /etc/disorder/config.USERNAME |
179 | containing the same thing as above. It can either be owned by the user and |
180 | mode 400, or owned by root and the user's group (if you have per-user |
181 | groups) and mode 440. |
182 | |
183 | You can use 'disorder authorize' to automatically pick passwords and |
184 | create these files. |
185 | |
186 | 11. Optionally source completion.bash from /etc/profile or similar, for |
187 | example: |
188 | |
189 | . /usr/local/share/disorder/completion.bash |
190 | |
191 | This provides completion over disorder command and option names. |
192 | |
193 | |
194 | Web Interface |
195 | ============= |
196 | |
197 | "Thought I was a gonner baby, but I'm bullet proof" |
198 | |
199 | These instructions assumes you are using Apache 1.3.x. |
200 | |
201 | You need to configure a number of things to make this work: |
202 | |
203 | 1. If you want to have a 'jukebox' virtual host, modify the DNS (or hosts file |
204 | if you are somehow reading this in the 1980s) accordingly and use a fragment |
205 | such as this one: |
206 | |
207 | <VirtualHost HOSTNAME> |
208 | DocumentRoot /home/jukebox/public_html |
209 | ServerName jukebox.DOMAIN |
210 | ServerAlias jukebox |
211 | ServerAdmin webmaster@DOMAIN |
212 | ErrorLog /var/log/apache/jukebox/error.log |
213 | TransferLog /var/log/apache/jukebox/access.log |
214 | Alias /static/ /usr/local/share/disorder/static/ |
215 | </VirtualHost> |
216 | |
217 | /static/ should point to the 'static' directory installed by DisOrder. If |
218 | you don't want to use the name 'static' then you can change the url.static |
219 | label in the web interface configuration to your preferred URL; see |
220 | disorder_config(5) for details. |
221 | |
222 | Don't forget to reload Apache after modifying its configuration. |
223 | |
224 | Separate logging is not required but I find it convenient. Up to you. |
225 | |
226 | 2. disorder.cgi assumes it is subject to access control (and in particular uses |
227 | the username to report who did what). Here's how I configured Apache, given |
228 | the above VirtualHost settings: |
229 | |
230 | <Directory /home/jukebox> |
231 | Require valid-user |
232 | AuthType basic |
233 | AuthName jukebox |
234 | AuthUserFile /home/jukebox/http.users |
235 | </Directory> |
236 | |
237 | Adjust this according to wherever you're going to install disorder.cgi and |
238 | its expected URL. |
239 | |
240 | Don't forget to reload apache after modifying its configuration. If you got |
241 | it wrong, fix it and restart Apache. |
242 | |
243 | 3. Create the password file configured above. Something like this: |
244 | |
245 | # htpasswd -b -c /home/jukebox/http.users myusername mypassword |
246 | Adding password for user myusername |
247 | # htpasswd -b /home/jukebox/http.users othername otherpass |
248 | Adding password for user othername |
249 | |
250 | 4. The jukebox must be configured to trust the web user. I added the following |
251 | line to my /etc/disorder/config: |
252 | |
253 | trust www-data |
254 | |
255 | This might not be the same on your system! You have to specify the user |
256 | that the CGI script runs as, whatever that is. |
257 | |
258 | 5. Install disorder.cgi in an appropriate location. Remember to make it |
259 | executable. With the above configuration I installed it as |
260 | ~jukebox/public_html/index.cgi. |
261 | |
262 | 6. Give www-data (or whatever user it is) a password and edit |
263 | /etc/disorder/config.private accordingly. This file should be mode 640 and |
264 | owned by root:jukebox. The line should look something like this: |
265 | |
266 | allow www-data MYPASSWORD |
267 | |
268 | After editing the config file, you must make the daemon re-read it: |
269 | |
270 | disorder reconfigure |
271 | |
272 | 7. Teach www-data its password, by putting it in /etc/disorder/config.www-data. |
273 | This file should be mode 640 and owned by root:www-data. |
274 | |
275 | password MYPASSWORD |
276 | |
277 | (You could also use ~www-data/.disorder/passwd for this but on some systems |
278 | the web server user's home directory is inside the document root, which |
279 | would have rather unfortunate consequences.) |
280 | |
281 | 8. Try it out. You should be asked for a username and password that you |
282 | configured earlier, and be shown details of what is playing and what other |
283 | tracks have been configured for future play. |
284 | |
285 | 9. Some features take time to start working, for instance those involving |
286 | reporting the length of tracks. This is because the server starts up as |
287 | quickly as possible even if the full track data has not yet been gathered; |
288 | the track data is then calculated in the background. |
289 | |
290 | 10. If you run into problems, always look at the appropriate error log; the |
291 | message you see in your web browser will usually not be sufficient to |
292 | diagnose the problem all by itself. |
293 | |
294 | 11. If you have a huge number of top level directories, then you might find |
295 | that the 'Choose' page is unreasonably large. If so add the following line |
296 | to /etc/disorder/options.user: |
297 | label sidebar.choosewhich choosealpha |
298 | |
299 | This will make 'Choose' be a link for each letter of the 26-letter Roman |
300 | alphabet; follow the link and you just get the directories which start with |
301 | that letter. The "*" link at the end gives you directories which don't |
302 | start with a letter. |
303 | |
304 | You can copy choosealpha.html to /etc/disorder and edit it to change the |
305 | set of initial choices to anything that can be expressed with regexps. The |
306 | regexps must be URL-encoded UTF-8 PCRE regexps. |
