Installing OpenDJ On Ubuntu

From IHRIS Wiki

Jump to: navigation, search

Installation

Prerequisites

We are going to install OpenDJ on Ubuntu 12.04 from a command line. Like ApacheDS, OpenDJ also requires a Java environment to run. OpenDJ requires at least Java version 6.0 installed on the machine that it is going to run.

Downloading OpenDJ software

The software can be downloaded from the OpenDJ download page. We are going to download the most recent version 2.5.

Installing OpenDJ

We are going to install OpenDJ in the /opt directory of our system. So we will create the OpenDJ installation directory here

sudo mkdir -p /opt/OpenDJ
sudo chown -R `whoami`:`whoami` /opt/OpenDJ

Download and unzip OpenDJ by running the following commands from the terminal

cd /opt/OpenDJ
wget http://download.forgerock.org/downloads/opendj/2.5.0-Xpress1/OpenDJ-2.5.0-Xpress1.zip
unzip OpenDJ-2.5.0-Xpress1.zip
mv OpenDJ-2.5.0-Xpress1 2.5.0
cd 2.5.0

To install OpenDJ in interactive mode, run the setup --cli from the terminal

Note: you will have to remember the password you set in [xxxx] as it is the one you'll be using to access the server

$ /opt/OpenDJ/2.5.0/./setup --cli
 
OpenDJ 2.5.0
Please wait while the setup program initializes...
 
What would you like to use as the initial root user DN for the Directory
Server? [cn=Directory Manager]: [cn=admin ENTER]
Please provide the password to use for the initial root user:[xxxx]
Please re-enter the password for confirmation:[xxxx]
 
Provide the fully-qualified directory server host name that will be used when
generating self-signed certificates for LDAP SSL/StartTLS, the administration
connector, and replication [sovello-1x88]: [ENTER]
 
On which port would you like the Directory Server to accept connections from
LDAP clients? [1389]: [ENTER]
 
On which port would you like the Administration Connector to accept
connections? [4444]: [ENTER]
 
Do you want to create base DNs in the server? (yes / no) [yes]
 
Provide the base DN for the directory data: [dc=moh,dc=gov,dc=rw]
Options for populating the database:
 
    1)  Only create the base entry
    2)  Leave the database empty
    3)  Import data from an LDIF file
    4)  Load automatically-generated sample data
 
Enter choice [1]: [1] (As we don't have to load anything now, all data will be loaded later)
 
Please specify the path to the LDIF file containing the data to import: [ENTER]
 
Do you want to enable SSL? (yes / no): [no]
 
Do you want to enable Start TLS? (yes / no): [no]
 
Do you want to start the server when the configuration is completed? (yes /no): [yes]

Start Server when the configuration is completed


What would you like to do?

    1)  Set up the server with the parameters above
    2)  Provide the setup parameters again
    3)  Print equivalent non-interactive command-line
    4)  Cancel and exit

See /tmp/opendj-setup-3175331027381066326.log for a detailed log of this operation.

Configuring Directory Server ..... Done.
Creating Base Entry dc=moh,dc=gov,dc=rw ..... Done.
Starting Directory Server ........ Done.

To see basic server configuration status and configuration you can launch /opt/OpenDJ/2.5.0/bin/status

Loading HPD schema and Provider schema to OpenDJ

We are going to load the provider schema for RHEA and the schema for the HPD Profile. We need to download the code for the Provider registry for Rwanda and then we will copy the schema files from there to OpenDJ.

cd /var/lib/iHRIS/
bzr branch lp:rhea-pr
cd /opt/OpenDJ/2.5.0/bin
./stop-ds
cp /var/lib/iHRIS/rhea-pr/ldap/openldap/* /opt/OpenDJ/2.5.0/config/schema
./start-ds

Loading Provider sample data

You need to move to the bin directory of OpenDJ and execute these commands from the terminal

cd /opt/OpenDJ/2.5.0/bin
./stop-ds
./import-ldif -l /var/lib/iHRIS/rhea-pr/ldap/admin_pass.ldif --backendID userRoot --includeBranch cn=admin,dc=moh,dc=gov,dc=rw
./import-ldif -l /var/lib/iHRIS/rhea-pr/ldap/base_organizational_units.ldif --backendID userRoot --includeBranch dc=moh,dc=gov,dc=rw
./import-ldif -l /var/lib/iHRIS/rhea-pr/ldap/ihris_sample_export.ldif --backendID userRoot --includeBranch dc=moh,dc=gov,dc=rw
./start-ds

At any time you can check the status of OpenDJ LDAP server by running

/opt/OpenDJ/2.5.0/bin/./status

When OpenDJ is running the output is like

sovello@sovello-1x88:~$ /opt/OpenDJ/2.5.0/bin/./status 


>>>> Specify OpenDJ LDAP connection parameters

Administrator user bind DN [cn=Directory Manager]: cn=admin

Installing OpenDJ DSML gateway

Prerequisites

DSML need to run in Apache Tomcat. So we first need to install Apache Tomcat the most recent version is 7. Run this command from the terminal

sudo apt-get install tomcat7

Installing Tomcat this way doesn't need you to go set up the environment variables for it. dpkg takes care of all the stuff. After it finishes you can access the Tomcat server from this url http://localhost:8080 in your browser.

If the installation was successful you should see a It Works with some other details.

Downloading OpenDJ DSML gateway

This OpenDJ DSML gateway runs independently of OpenDJ Directory server. It can be downloaded from the Archive of stable community releases page

You can also download it from the command line.

wget http://download.forgerock.org/downloads/opendj/2.5.0-Xpress1/OpenDJ-2.5.0-Xpress1-DSML.war

Installing and Configuring

The name of the war needs to be changed to dsml.war.

Issue the following commands on the terminal to install/deploy the war file.

sudo service tomcat7 stop
sudo cp path/to/dsml.war /var/lib/tomcat7/webapps/
sudo service tomcat7 start

If it worked correctly, a folder dsml will be created in /var/lib/tomcat7/webapps/dsml

For the DSML Gateway to work, the file WEB-INF/web.xml has to be edited. At minimum, the LDAP port number is to be the one you set during installation. (If need be, for HTTP Basic Auth and have the user IDs mapped to entries in the directory, for example, this has to be set to ldap.authzidtypeisid=true.)

sudo pico /var/lib/tomcat7/webapps/WEB-INF/web.xml

Then edit this part

  <context-param>
    <description>The port number of the OpenDJ server; e.g., 389</description>
    <param-name>ldap.port</param-name>
    <param-value>389</param-value>
  </context-param>

to

  <context-param>
    <description>The port number of the OpenDJ server; e.g., 389</description>
    <param-name>ldap.port</param-name>
    <param-value>1389</param-value>
  </context-param>

Restart tomcat to take your changes into account.

sudo service tomcat7 restart

Testing OpenDJ DSML Gateway

To test DSML gateway we were to access http://localhost:8080/dsml/DSMLServlet however, the DSMLServlet url only accepts POST requests. so we would be presented with an error.

We can test the DSML Gateway using Jxplorer' which we will need to install and run

sudo apt-get install jxplorer

After it finishes open it and then go to File -> Connect or simply click the Connect icon from the toolbar and fill in the details as seen from the picture below:

JXplorer Parameters to access OpenDJ LDAP Server

If it works OK, we should see this screen.
