7. Installing MMBase

Download the binary distribution of MMBase, and the additional applications you need (i.e. CloudContext Security, Media, Email) (see the next section), from:
http://www.mmbase.org/ --> Download --> Releases

MMBase version 1.7.2 contained a nasty bug, resulting in problems with the editwizards. The 1.7.3 release includes a bugfix for this problem.

Make sure you pick out the right version for the Java 2 JDK installed on your system. You can find out the version currently installed by typing:
java -version

Extract the binary distribution of MMBase, copy it into the Tomcat directory, and change the ownership of the MMBase directory:
unzip mmbase-xxx.zip cd /usr/local/tomcat/webapps/ mkdir mmbase-webapp/ cp -R .../mmbase-x.x.x/mmbase-webapp/* ./mmbase-webapp/ chown -R tomcat:tomcat ./mmbase-webapp/

Installing MMBase version 1.7 on Tomcat version 5 resulted in version incompatibilities:
FATAL org.mmbase.servlet.MMBaseStartThread - Could not find the MMBase module!Class javax/servlet/http/HttpServletResponse violates loader constraints

We had to disable the RMMCI library to get this installation up and running:
mv /usr/local/tomcat/webapps/web-app/WEB-INF/lib/mmbase-rmmci.jar \ /usr/local/tomcat/webapps/web-app/WEB-INF/lib/mmbase-rmmci.jar.org

For MMBase version 1.7 running on Tomcat version 5, enable the Xerces libraries:
mv /usr/local/tomcat/webapps/mmbase-webapp/WEB-INF/lib/xalan.renametojar \ /usr/local/tomcat/webapps/mmbase-webapp/WEB-INF/lib/xalan.jar mv /usr/local/tomcat/webapps/mmbase-webapp/WEB-INF/lib/xerces.renametojar \ /usr/local/tomcat/webapps/mmbase-webapp/WEB-INF/lib/xerces.jar mv /usr/local/tomcat/webapps/mmbase-webapp/WEB-INF/lib/xml-apis.renametojar \ /usr/local/tomcat/webapps/mmbase-webapp/WEB-INF/lib/xml-apis.jar
Or you will have fatal errors like:
FATAL org.mmbase.servlet.MMBaseStartThread - Could not find the MMBase module!org/apache/xpath/XPathAPI

For MMBase version 1.6 running on Tomcat version 4, replace the Tomcat Xerces libraries by those coming with MMBase:
mv -i /usr/local/tomcat/common/endorsed/xercesImpl.jar ~/ mv -i /usr/local/tomcat/common/endorsed/xmlParserAPIs.jar ~/ cp /usr/local/tomcat/webapps/mmbase-webapp/WEB-INF/lib/xalan.jar \ /usr/local/tomcat/common/endorsed/ chown tomcat:tomcat /usr/local/tomcat/common/endorsed/xalan.jar chmod 644 /usr/local/tomcat/common/endorsed/xalan.jar cp /usr/local/tomcat/webapps/mmbase-webapp/WEB-INF/lib/xerces.jar \ /usr/local/tomcat/common/endorsed/ chown tomcat:tomcat /usr/local/tomcat/common/endorsed/xerces.jar chmod 644 /usr/local/tomcat/common/endorsed/xerces.jar cp /usr/local/tomcat/webapps/mmbase-webapp/WEB-INF/lib/xml-apis.jar \ /usr/local/tomcat/common/endorsed/ chown tomcat:tomcat /usr/local/tomcat/common/endorsed/xml-apis.jar chmod 644 /usr/local/tomcat/common/endorsed/xml-apis.jar

If you will not be using an Apache JK 2 mapping or reverse proxy (see further below) as a front-end to your MMBase server, you can add to the file /usr/local/tomcat/conf/server.xml:
<Context path="/mmbase" docBase="/usr/local/tomcat/webapps/mmbase-webapp" debug="0">  <Resources className="org.apache.naming.resources.FileDirContext" allowLinking="true" /> </Context>

This will allow you to access your MMBase server using (replace <hostname> with your hostname):
http://<hostname>:8080/mmbase

instead of:
http://<hostname>:8080/mmbase-webapp

Check if the ImageMagick convert tool is in your path:
which convert

If not, add it to /usr/local/tomcat/webapps/mmbase-webapp/WEB-INF/config/applications/Resources/builders/images.xml. For example:
<property name="ImageConvert.ConverterCommand">/usr/bin/X11/convert</property>

Make sure that the directory /usr/local/tomcat/webapps/mmbase-webapp/WEB-INF/config/builders/applications is writable by the servlet engine user (for auto-installing builders):
chown tomcat:tomcat /usr/local/tomcat/webapps/mmbase-webapp/WEB-INF/config/builders/applications chmod 775 /usr/local/tomcat/webapps/mmbase-webapp/WEB-INF/config/builders/applications
