MMBase Installation HOWTO
Prev |  | Next

# 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">
      <!-- if you want symlinks to work: -->
      <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
