54 <h1>Installation</h1>
|
|
|
55
|
|
|
56 <h2>On Linux/Unix</h2>
|
|
|
57
|
|
|
58 <ol>
|
|
|
59 <li>Make shure the Java JDK is installed (a JRE won't do).</li>
|
|
|
60
|
|
|
61 <li>Create a base directory for digilib (the default used here is
|
|
|
62 <code>/docuserver</code>) and for the web interface
|
|
|
63 (<code>/docuserver/www</code>).</li>
|
|
|
64
|
|
|
65 <li>Unpack the <b>digilib-core.zip</b> package in the web
|
|
|
66 interface directory (<code>/docuserver/www</code>). This will create
|
|
|
67 the digilib directory <code>digitallibrary</code>.</li>
|
|
|
68
|
|
|
69 <li>Install the auxiliary Java libraries in
|
|
|
70 <code>digitallibrary/WEB-INF/lib</code>. (Or just unpack the
|
|
|
71 <b>digilib-ext.zip</b> package there.)</li>
|
|
|
72
|
|
|
73 <li>Unpack Jakarta Tomcat 5.0.29 in <code>/docuserver</code> This should
|
|
|
74 produce a directory <code>/docuserver/jakarta-tomcat-5.0.29</code>. Create a
|
|
|
75 link <code>/docuserver/tomcat</code> to the new directory.</li>
|
|
|
76
|
|
|
77 <li>Create a link from the digilib directory into the Tomcat webapps
|
|
|
78 directory <code>/docuserver/tomcat/webapps</code> (type <code>ln -s
|
|
|
79 /docuserver/www/digitallibrary /docuserver/tomcat/webapps/</code>) This installs
|
|
|
80 digilib in the default Tomcat instance running on port 8080 as
|
|
|
81 <code>http://myserver:8080/digitallibrary/</code>.</li>
|
|
|
82
|
|
|
83 <li>Adjust the path to the JDK and its options in
|
|
|
84 <code>catalina.sh</code> (in the directory
|
|
|
85 <code>/docuserver/tomcat/bin</code>, see below for details)</li>
|
|
|
86 </ol>
|
|
|
87
|
|
|
88
|
|
|
89 <h2>On Windows (quick install)</h2>
|
|
|
90
|
|
|
91 <ol>
|
|
|
92 <li>Set the following Environment Variables:<br />
|
|
|
93 <code>CATALINA_HOME = C:\jakarta-tomcat-4.1.24</code> (or similar)<br />
|
|
|
94 <code>JAVA_HOME = C:\j2sdk</code> (or similar)
|
|
|
95 </li>
|
|
|
96
|
|
|
97 <li>
|
|
|
98 Start Tomcat server: Open a console window (start <code>cmd.exe</code>).<br />
|
|
|
99 Type: <code>%CATALINA_HOME%\bin\startup</code>
|
|
|
100 </li>
|
|
|
101
|
|
|
102 <li>
|
|
|
103 Try the following URL in your browser:
|
|
|
104 <code>http://localhost:8080</code> or
|
|
|
105 <code>http://127.0.0.1:8080</code>
|
|
|
106 </li>
|
|
|
107
|
|
|
108 <li>
|
|
|
109 You should now be able to see the Tomcat opening screen: <em>If you're seeing this page via a web browser, it means you've setup Tomcat successfully. Congratulations!</em>
|
|
|
110 </li>
|
|
|
111
|
|
|
112 <li>
|
|
|
113 Shut it down again: In the console window type <code>%CATALINA_HOME%\bin\shutdown</code>.
|
|
|
114 </li>
|
|
|
115
|
|
|
116 <li>
|
|
|
117 Extract the <b>diglib-core.zip</b> package, possibly to <code>C:\docuserver</code>.
|
|
|
118 </li>
|
|
|
119
|
|
|
120 <li>
|
|
|
121 Install the auxiliary Java libraries in <code>digitallibrary\WEB-INF\lib</code>.
|
|
|
122 (Or just unpack the <b>digilib-ext.zip</b> package there.)
|
|
|
123 </li>
|
|
|
124
|
|
|
125 <li>
|
|
|
126 Modify the following configuration files according to your paths (as in the "On Linux" section):
|
|
|
127 <br>
|
|
|
128 For tomcat
|
|
|
129 <ul>
|
|
|
130 <li><code>C:\jakarta-tomcat-4.1.24\conf\server.xml</code></li>
|
|
|
131 <li><code>C:\jakarta-tomcat-4.1.24\conf\tomcat-users.xml</code></li>
|
|
|
132 </ul>
|
|
|
133 For digilib
|
|
|
134 <ul>
|
|
|
135 <li><code>C:\docuserver\digitallibrary\WEB-INF\digilib-config.xml</code></li>
|
|
|
136 <li><code>C:\docuserver\digitallibrary\WEB-INF\digilib-auth.xml</code></li>
|
|
|
137 </ul>
|
|
|
138 In the <code>alcatraz-win-conf.zip</code> package you can find
|
|
|
139 prepared configuration files with the following default values:
|
|
|
140 <ul>
|
|
|
141 <li>The image file directory is <code>C:\bilder</code>. </li>
|
|
|
142 <li>The username for viewing image files is <code>digilib</code>.</li>
|
|
|
143 <li>The password for viewing image files is <code>digilib</code>.</li>
|
|
|
144 <li>The digilib server runs on Port <code>9090</code>.</li>
|
|
|
145 </ul>
|
|
|
146 </li>
|
|
|
147
|
|
|
148 <li>
|
|
|
149 Now you can restart the Tomcat server: <code>http://localhost:9090</code> or
|
|
|
150 <code>http://127.0.0.1:9090</code>.
|
|
|
151 </li>
|
|
|
152
|
|
|
153 <li>
|
|
|
154 Watch the images:

164 <h3>catalina.sh / catalina.bat</h3>
|
|
|
165
|
|
|
166 <p>The file <code>catalina.sh</code> (in <code>/docuserver/tomcat/bin</code>
|
|
|
167 can be modified to provide the path to the JDK and runtime options
|
|
|
168 for the Java VM. Somewhere at the beginning of the file you can put two lines
|
|
|
169 like this:</p>
|
|
|
170
|
|
|
171 <pre>
|
|
|
172 export JAVA_HOME=/usr/local/lib/IBMJava2-14

173 export CATALINA_OPTS="-mx512m"
|
|
|
174 </pre>

175

176 <p>or, on Windows<p>

|
|
|
181 </pre>
|
|
|
182
|
|
|
183 <p>Adjust the <code>JAVA_HOME</code> path to point to your Java JDK
|
|
|
184 installation directory. You can adjust the memory used by the Java VM
|
|
|
185 with the <code>-mx</code> option.</p>

188 <h3>tomcat-users.xml</h3>
|
|

189
|
|
|
190 <p>All passwords and usernames have to be set up in the file
|
|
|
191 <code>tomcat-users.xml</code> in <code>/docuserver/tomcat/conf</code> if you
|
|
|
192 want to use authentication in digilib. The file looks like this:</p>
|
|
|
193
|
|
|
194 <pre>
|
|
|
195 <tomcat-users>
|

199 </tomcat-users>
|
|

200 </pre>
|
|
|
201
|
|
|
202 <p>A user is identified by a <code>name</code> and
|
|
|
203 <code>password</code>. These two elements have to be entered in a
|
|
|
204 authentication form presented by the browser when accessing a
|
|
|
205 restricted resource. A user can have one or more
|
|
|
206 <code>roles</code>. These roles will be used by digilib to decide if
|
|
|
207 an authenticated user is allowed to access a document (see
|
|
|
208 <code>digilib-auth.xml</code> below).</p>
|
|
|
209
|
|
|
210 <p>If you want to use the webinterface to configure Tomcat, you have to
|
|
|
211 add administrational account with the roles <code>admin</code> and
|
|
|
212 <code>manager</code>.</p>
|
|
|
213
|
|
|
214 <p>tomcat has to be restarted before changes to
|
|
|
215 <code>tomcat-users.xml</code> have effect!</p>

222 <p>The main configuration for digilib is

224 <code>WEB-INF</code> directory in the webapp. (If you really need

|
|

357 sufficient to access a resource the user will be asked for username
