Changing base directory of drupal


This can be done in several easy steps.

1. Change the base dir in your settings.php to point to your root folder (public_html).

You can edit the file from your cPanel -> File Manager in the following way:

- Navigate to your /sites/default directory.
- Click on the letters next to the icon of settings.php
- A little box should appear on the top-right side of the page.
- Click on Edit File Contents and you should be able to edit the file.

2. Change the RewriteBase dir in your .htaccess file to be /

The contents of your .htaccess file should contain a line like the one below:

RewriteBase /

You can edit this file in the same way as you did with your settings.php file.

3. After that you should move all the Drupal files which are under your subdirectory to your root (public_html) folder. The best and easiest way to do this is using an FTP client.

Cron Job in Mac OSX Version 10.5 +

| No Comments

Source Drupal

MacOS X after 10.5 no longer seems to use cron and has replaced it by launchd. This uses plist files to register jobs to run. To access cron.php using launchd place the following file in /Users/your_account/Library/LaunchAgents/com.your_site.drupal_cron (create the directory if necessary):


This will then get loaded when you login and will visit the cron.php page every 300 seconds (5 minutes). To make it take affect you need to logout/login or use the terminal to run launchctl to load it immediately:

launchctl load /Users/your_account/Library/LaunchAgents/com.your_site.drupal_cron

If you need to change the plist file you can unload and reload it again with:

launchctl unload /Users/your_account/Library/LaunchAgents/com.your_site.drupal_cron
launchctl load /Users/your_account/Library/LaunchAgents/com.your_site.drupal_cron

(If you have XTools installed you can use /Developer/Applications/Utilities/Property List Editor to create plist files.)

Installing Islandora module

| 1 Comment


Below is a quick check list of items to be done/installed when installing Islandora.  Some of the items in the list will lead to pages of their own documenting how to do that step.

  • Install Java - steps to do this would depend on your os.
         you can check if your machine has java by typing java -version in the terminal.
         x-134-84-47-23:bin birage$ java -version
         java version "1.6.0_15"
        Java(TM) SE Runtime Environment (build 1.6.0_15-b03-219)
        Java HotSpot(TM) 64-Bit Server VM (build 14.1-b02-90, mixed mode  
         In Mac it is installed at /Library/Java/Home so JAVA_HOME should be set accordingly    
  • Install Ant - see  Ant is useful when installing gsearch.
  • Set Environment variables such as JAVA_HOME and FEDORA_HOME.  See the Installation and Configuration Guide#Prepare Environment Variables
  • Install Mysql - steps to do this would depend on your os.  We are assuming Drupal will have a mysql database as its backend.
  • Install Postgres - steps to do this would depend on your os.  Postgres is optional.  You may want to use it as the Fedora database.  Mysql could also be used for the Fedora database.
  • Create a database schema for Fedora.  Steps to do this would depend on you chosen database.  See the Installation and Configuration Guide#Database
  • Download and Install Fedora.  See the Installation and Configuration Guide#Installation.  You can see how we answered the Fedora installation questions for a test server here.
  • Download and install gsearch.  Optional but recommended.  See the gsearch guide for instructions.
  • Edit the tomcat-users.xml file.  Optional but helpful if you want to start and stop individual webapps without shutting down tomcat.  More information on tomcat can be found here.
  • Install the Fedora demo objects.  See the Demostrations guide.
  • Edit the fedora-users.xml file.  Optional but recommended, if you want to allow anonymous access to  Fedora through Islandora this will have to be done.  See the Islandora Guide.
  • Install the DrupalFilter servlet filter.  See the Islandora Guide.
  • Install Apache httpd server.  Installation will depend on your os.
  • Enable url rewriting for Apache.  You would have to enable mod-rewrite.  Again this depends on your os.  Some info is available here.
  • Install and configure php.  There is some info in the Islandora Guide#Requirements regarding this.
  • Install Imagemagick.  This is optional but recommended as some of the default Content models use it.  Installing Imagemack would is system dependant so the steps would depend on your os.
  • Download and install Drupal.  See for instructions.
  • Install the Drupal Imageapi module.  This module is used by some Islandora content models. LINK
  • Download and install the fedora_repository module.  See the Islandora Guide#Installation.
  • Enable the repository module.  Optionally enable the fedora_imageapi module.  See the Islandora Guide#Installation.
  • Create Drupal roles to assign to users.  One role you should create for sure is administrator.  This role has special rights in Fedora so don't assign this to anyone but an actual administrator.
  • Create Drupal users and give them roles.  For users to authenticate to Fedora they must have a role.  The default roles are not enough.  You must assign a role that has been created.  See
  • See the Making the Demo SmileyStuff Islandora Aware page.
  • Visit the Islandora admin page and ingest the demo objects.  See the Islandora Guide.
  • Create your own Content Models and Collection Policies.  See the Islandora Guide#CreatinganIslandoraContentModel.
  • If gsearch is installed and you want to search more then the default fields modify the appropriate luceneToFoxml.xslt.  See the Gsearch guide.
  • Edit Islandora searchTerms.xml file.  If you have customized the fields indexed by lucene you can update the searchTerms.xml to let Islandora know what fields you want to search.  See the Islandora Guide#EnablingSearchandAdvancedSearch.
  • Enable the advanced search block.  See the Islandora Guide#EnablingSearchandAdvancedSearch.

Installing Fedora Commons Repository

First install MySQL Server and create a database to use with Fedora:

x-134-84-44-46:bin birage$ ./mysql -u root -p
Enter password:
Welcome to the MySQL monitor. Commands end with ; or \g.
Your MySQL connection id is 7
Server version: 5.1.44 Source distribution

Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.

mysql> CREATE DATABASE fedora3 default charset utf8;
Query OK, 1 row affected (0.02 sec)

mysql> GRANT ALL ON fedora3.* TO adminFedora@localhost IDENTIFIED BY 'adminFedora';
Query OK, 0 rows affected (0.02 sec)

Query OK, 0 rows affected (0.00 sec)

Now Proceed with your Fedora installation:

Download fedora binary and extract fcrepo-installer-3.4.jar
and from the terminal run the command from the directory > java -jar fcrepo-installer-3.4.jar

Installing Apache Solr Drupal Module on Tomcat


Installing Apache Solr in Tomcat for Drupal (Snow Leopard)

(Note: If you are planning to use FEDORA on Tomcat then FEDORA installation offers to install an instance of Tomcat which is very easy and saves a lot of time. Check out this link for more details)

There's quite a few information available on how to install Apache Solr for your Drupal website. One of the best places to start is the Apache Solr Search Integration module documentation page. In this post I will gather all the bits and pieces for installing Solr in Tomcat on one specific platform: Snow Leopard. This is the platform I'm developing Drupal sites on and the great thing is it has all the needed Java stuff built in, so it's quite easy to install Solr and Tomcat.

Install guide

  • Download and install the Apache Solr Search Integration module. 
  • Download the Apache Solr PHP Client. As of the module requires revision 22.
  • Extract this package and move the resulting folder to the module folder. You will now have something like [YOUR-MODULES-FOLDER]/apachesolr/SolrPhpClient/Apache/Solr/Service.php. 
  • Download Apache Solr. You might find a faster and newer version for your location on the downloads overview page.
  • Extract this package and move it to a folder of your liking. I'm using ~/bin/apache-solr-1.4.0.
  • Copy solrconfig.xml and schema.xml from the module folder to the Solr instance configuration folder. In my case this is in ~/bin/apache-solr-1.4.0/example/solr/conf. You might want to rename the schema and config file in that folder first to keep a backup. Download the core binary distribution of Apache Tomcat 6 (direct link for 6.0.24). Extract this package and move it to a folder of your liking. I'm using ~/bin/apache-tomcat-6.0.24. 
  • Copy the Solr web application~/bin/apache-solr-1.4.0/dist/apache-solr-1.4.0.war to your Tomcat webapps folder and rename it to solr.war. In my case this resulted in ~/bin/apache-tomcat-6.0.24/webapps/solr.war. Start and immediately shutdown Tomcat by running the following in your terminal (from your home folder): ~/bin/apache-tomcat-6.0.24/bin/ ~/bin/apache-tomcat-6.0.24/bin/ Note that the exact Tomcat folder name might depend on the Tomcat version you downloaded..
  • This will unpack the war file resulting in a folder ~/bin/apache-tomcat-6.0.24/webapps/solr/.
  • We now just have to point the Solr web application in Tomcat to the Solr example application. You can do this by adjusting the web application configuration file (WEB-INF/web.xml). Uncomment the section specifying the solr/home environment variable and set its value to the path of your Solr example application folder. In my case the configuration file was located at ~/bin/apache-tomcat-6.0.24/webapps/solr/WEB-INF/web.xml and after replacing the solr/home section I had  solr/home /Users/biraj/bin/apache-solr-1.4.0/example/solr java.lang.String
  • Make sure you uncomment the tags . I wasted couple of hours because I did not notice it. And use the absolute path to the solr/conf path. ~ often causes problems.
  • Your system is now set up and you can start Tomcat now issueing the following command in your terminal. ~/bin/apache-tomcat-6.0.24/bin/
  • You can access the Solr admininstration interface now at http://localhost:8080/solr/admin/.
