This guide shows you how to install OpenDJ directory services. The OpenDJ project offers open source LDAP directory services in Java.

Preface

This guide shows you how to install, upgrade, and remove OpenDJ software. Unless you are planning a throwaway evaluation or test installation, read the Release Notes before you get started.

If you want only to try OpenDJ server software, and you do not plan to store any real or important data that you want to keep, then you need not read this entire guide. Instead, try Installing OpenDJ With the QuickSetup Wizard.

1. Who Should Read this Guide

This guide is written for anyone installing OpenDJ who plans to maintain directory services for client applications. Basic OpenDJ installation, especially using Java WebStart, can be simple and straightforward, particularly if you are already acquainted with directory services. Upgrading a running directory service without a single point of failure that can cause downtime requires at least a little thought and planning. Also, even in the case of basic installation, you may find yourself wanting more background about what you are doing.

This guide covers the install, upgrade, and removal (a.k.a. uninstall) procedures that you theoretically perform only once per version. This guide aims to provide you with at least some idea of what happens behind the scenes when you perform the steps.

You do not need to be an LDAP wizard to learn something from this guide, though a background in directory services and maintaining server software can help. You do need some background in managing servers and services on your operating system of choice. You can nevertheless get started with this guide, and then learn more as you go along.

2. Formatting Conventions

Most examples in the documentation are created in GNU/Linux or Mac OS X operating environments. If distinctions are necessary between operating environments, examples are labeled with the operating environment name in parentheses. To avoid repetition file system directory names are often given only in UNIX format as in /path/to/server, even if the text applies to C:\path\to\server as well.

Absolute path names usually begin with the placeholder /path/to/. This path might translate to /opt/, C:\Program Files\, or somewhere else on your system.

Command-line, terminal sessions are formatted as follows:

$ echo $JAVA_HOME
/path/to/jdk

Command output is sometimes formatted for narrower, more readable output even though formatting parameters are not shown in the command.

Program listings are formatted as follows:

class Test {
    public static void main(String [] args)  {
        System.out.println("This is a program listing.");
    }
}

3. Accessing Documentation Online

ForgeRock publishes comprehensive documentation online:

  • The ForgeRock Knowledge Base offers a large and increasing number of up-to-date, practical articles that help you deploy and manage ForgeRock software.

    While many articles are visible to community members, ForgeRock customers have access to much more, including advanced information for customers using ForgeRock software in a mission-critical capacity.

  • ForgeRock product documentation, such as this document, aims to be technically accurate and complete with respect to the software documented. It is visible to everyone and covers all product features and examples of how to use them.

4. Using the ForgeRock.org Site

The ForgeRock.org site has links to source code for ForgeRock open source software, as well as links to the ForgeRock forums and technical blogs.

If you are a ForgeRock customer, raise a support ticket instead of using the forums. ForgeRock support professionals will get in touch to help you.

Chapter 1. Installing OpenDJ With the QuickSetup Wizard

If you want only to try OpenDJ server software, and you do not plan to store any real or important data that you want to keep, then read only this chapter, or just try out installation without reading any further.

Download OpenDJ software from one of the following locations.

  • The ForgeRock BackStage downloads page has the latest stable, supported release of OpenDJ and the other products from ForgeRock.

  • The Nightly Builds page posts links to the latest nightly builds of OpenDJ software. Note that these builds are the working version from the trunk and are not for use in a production environment.

  • The Community Archives page includes stable community builds for previous releases of OpenDJ software.

QuickSetup uses Java WebStart to let you perform an installation of OpenDJ directory server starting with a click in your web browser, which can be a great way to try OpenDJ directory server for the first time, or to do a quick test installation.

Note

OpenDJ directory server relies on Java 6 or later, so if your browser picks up an old installation of Java 5 for example, installation can fail. You might see an application error message such as this:

Application error due to old Java version

If the WebStart installation does not work in your browser, copy the WebStart URL, ending in QuickSetup.jnlp, from the OpenDJ download page. Next, pass the link as an argument to the javaws command in a terminal window to start the installer.

$ export PATH=/path/to/java/bin:$PATH
$ javaws URL-to-QuickSetup-Installer

The WebStart installer corresponds to what you start if you download OpenDJ-2.6.0.zip, unzip the file, and then run opendj/setup (UNIX), opendj\setup.bat (Windows), or opendj/QuickSetup.app (Mac OS X).

Java WebStart launches the the QuickSetup wizard, and soon the Welcome screen appears.

To launch OpenDJ Control Panel again later, you can run one of the following, depending on your host system.

  • (Mac OS X) opendj/bin/ControlPanel.app

    If you encounter an error message when starting the Control Panel on Mac OS X, see the solution described in Section 25.3, "Troubleshooting OpenDJ Utilities" in the Administration Guide.

  • (UNIX) opendj/bin/control-panel

  • (Windows) opendj\bat\control-panel.bat

Chapter 2. Installing OpenDJ From the Command Line

This chapter covers command-line installation with additional information on setup options.

Procedure 2.1. To Prepare For Installation
  1. Make sure you have the correct Java environment installed, as described in the Release Notes section on Java Environment in the Release Notes requirements.

    If your default Java environment is not appropriate, set OPENDJ_JAVA_HOME to the path to the correct Java environment, or set OPENDJ_JAVA_BIN to the absolute path of the java command. The latter environment variable is useful for example if you have both 32-bit and 64-bit versions of the Java environment installed, and want to make sure you use the 64-bit version.

  2. Download OpenDJ software from one of the following locations.

    • The ForgeRock BackStage downloads page has the latest stable, supported release of OpenDJ and the other products from ForgeRock.

    • The Nightly Builds page posts links to the latest nightly builds of OpenDJ software. Note that these builds are the working version from the trunk and are not for use in a production environment.

    • The Community Archives page includes stable community builds for previous releases of OpenDJ software.

    The following server software is available.

    OpenDJ-2.6.0.zip

    Cross-platform OpenDJ directory server installation files

    opendj_2.6.0-1_all.deb

    OpenDJ directory server native package for Debian and related Linux distributions.

    opendj-2.6.0-1.noarch.rpm

    OpenDJ directory server native package for Red Hat and related Linux distributions.

    OpenDJ-2.6.0-DSML.war

    Cross-platform OpenDJ DSML gateway web archive

    opendj-rest2ldap-servlet-2.6.0-servlet.war

    Cross-platform OpenDJ REST LDAP gateway web archive

  3. If you plan to install OpenDJ DSML gateway or OpenDJ REST LDAP gateway, make sure you have an appropriate application server installed.

  4. If you plan to configure SSL or TLS to secure network communications between the server and client applications, get a properly signed digital certificate that your client applications recognize, such as one that fits with your organization's PKI or one provided by a recognized certificate authority.

    To use the certificate during installation, the certificate must be located in a key store provided with Java (JKS, JCEKS, PKCS#12), or on a PKCS#11 token. To import a signed certificate into a key store, you can use the Java keytool command.

    See Preparing For Secure Communications in the Administration Guide in the Administration Guide for examples.

Procedure 2.2. To Install OpenDJ Directory Server
  1. Unzip OpenDJ-2.6.0.zip in the file system directory where you want to install the server.

    Unlike the web-based Quick Setup install, the setup command uses the directory where you unzipped the files as the installation directory, and does not ask you where to install OpenDJ. Therefore, if you want to install elsewhere on the file system, unzip the files in that location.

  2. Run the setup --cli command found in the opendj directory.

    This command starts the setup program in interactive mode on the command line, prompting you for each option. Alternatively, use additional setup options to specify values for the options you choose during interactive mode, thus scripting the installation process. See setup --help and the notes below.

    To perform a non-interactive, silent installation, provide all the options to configure OpenDJ, and then also use the -n or --no-prompt option.

    The setup command without the --cli option runs the Quick Start GUI installer with your local version of software, as does Java WebStart with a remote version of the software.

    $ /path/to/opendj/setup --cli

    Starting Directory Server ........... Done.
    
    To see basic server configuration status and configuration you can launch \
    /path/to/opendj/bin/status

    Some notes on the options follow.

    Initial root user DN

    The root user Distinguished Name identifies a user who can perform all administrative and other operations allowed for the server, called root user due to the similarity to the UNIX root. The default, cn=Directory Manager, is a well-known name. If you have reason to be paranoid, you might opt for a different name.

    Initial root user password

    The root user will use simple, password-based authentication. Later you can limit clear text access to avoid snooping, but for now use a strong password here unless this is a throwaway server.

    Fully-qualified directory server host name

    OpenDJ uses fully-qualified host name in self-signed certificates and for identification when you use replication. If you are installing a single server temporarily for evaluation, and are not concerned about replication and whether self-signed certificates can be trusted, then you can use an FQDN such as localhost.localdomain. Otherwise, use an FQDN that other hosts can resolve to reach your server.

    LDAP port

    The default for LDAP is 389. If you are working as a user who cannot open port 389, setup suggests 1389 by default.

    Administration port

    This is the service entrance used to configure the server, run tasks, and so forth. The default is 4444.

    Create base DNs

    You need a base Distinguished Name, such as dc=example,dc=com, to add directory data. If you already have LDIF, the base DN you want is the distinguished name suffix common to all entries in your LDIF. You can provide more than one base DN if your data belongs in more than one suffix.

    Import LDIF

    LDAP data interchange format is the standard text format for expressing LDAP data. If you have LDIF already, one reason you might not want to import the data at the same time you install is because your data uses attributes not defined in the default schema, and so you will wait to add schema definitions before you import.

    If you have a huge data set to import, you no doubt should also increase the import cache size, which you can do by passing a Java properties file. You might also prefer to perform data import offline.

    Enable SSL and TLS

    Enabling Secure Sockets Layer or Transport Layer Security lets you protect the network traffic between directory clients and your server.

    SSL

    SSL requires its own, separate port for LDAPS traffic. The default port for LDAPS is 636. If you are working as a user who cannot open port 636, setup suggests 1636 by default.

    TLS

    TLS lets you use StartTLS to negotiate a secure connection between a client and server, starting from the same server port you configured for LDAP.

    X.509 certificates

    The digital certificate you need for SSL and TLS can be self-signed and created on the fly. Trouble is, client applications view self-signed certificates like fake IDs, and so do not trust them. Self-signed certificates facilitate testing, but are not intended for production use.

    Start the server

    If you do not start the server during installation, you can use the /path/to/opendj/bin/start-ds command later.

  3. Run the status command to make sure your OpenDJ server is working as expected.

    $ /path/to/opendj/bin/status

Note

You can install OpenDJ in unattended and silent fashion, too. See the procedure, Procedure 2.5, "To Install OpenDJ Directory Server With a Properties File".

Procedure 2.3. To Install From the Debian Package

On Debian and related Linux distributions such as Ubuntu, you can install OpenDJ directory server from the Debian package.

  1. (Optional) Before you install OpenDJ, install a Java runtime environment if none is installed yet.

    $ sudo apt-get install default-jre
  2. Install the OpenDJ directory server package.

    $ sudo dpkg -i opendj_2.6.0-1_all.deb
    Selecting previously unselected package opendj.
    (Reading database ... 185569 files and directories currently installed.)
    Unpacking opendj (from opendj_2.6.0-1_all.deb) ...
    
    Setting up opendj (2.6.0) ...
    $

    The .deb installs OpenDJ directory server in the directory /opt/opendj.

    The files are owned by root by default, making it easier to have OpenDJ listen on ports 389 and 636.

  3. Configure OpenDJ directory server by using the command sudo /opt/opendj/setup.

    $ sudo /opt/opendj/setup --cli
    ...
    To see basic server configuration status and configuration you can launch
     /opt/opendj/bin/status
  4. (Optional) Check OpenDJ directory server status.

    $ sudo /opt/opendj/bin/status
    
    
    >>>> Specify OpenDJ LDAP connection parameters
    
    Administrator user bind DN [cn=Directory Manager]:

    Entries:     2002
    Replication: 
  5. (Optional) If you want to run OpenDJ when the system starts, see create-rc-script in the Administration Guide.

Procedure 2.4. To Install From the RPM Package

On Red Hat and related Linux distributions such as Fedora and CentOS, you can install OpenDJ directory server from the RPM package.

  1. Log in as superuser to install the software.

    $ su
    Password:
    # 
  2. (Optional) Before you install OpenDJ, install a Java runtime environment if none is installed yet.

    You might need to download an .rpm to install the Java runtime environment, and then install it using the rpm command.

    # rpm -ivh jre-*.rpm
  3. Install the OpenDJ directory server package.

    # rpm -i opendj-2.6.0-1.noarch.rpm
    Pre Install - initial install
    Post Install - initial install
    
    #

    The .rpm installs OpenDJ directory server in the directory /opt/opendj.

    The files are owned by root by default, making it easier to have OpenDJ listen on ports 389 and 636.

  4. Configure OpenDJ directory server by using the command /opt/opendj/setup.

    # /opt/opendj/setup --cli
    ...
    To see basic server configuration status and configuration you can launch
     /opt/opendj/bin/status
  5. (Optional) Check OpenDJ directory server status.

    # /opt/opendj/bin/status
    
    
    >>>> Specify OpenDJ LDAP connection parameters
    
    Administrator user bind DN [cn=Directory Manager]:

    Entries:     2002
    Replication: 
  6. (Optional) If you want to run OpenDJ when the system starts, see create-rc-script in the Administration Guide.

Procedure 2.5. To Install OpenDJ Directory Server With a Properties File

You can install OpenDJ directory server by using the setup command with a properties file.

Property names correspond to the option names, but without leading dashes. Options that take no arguments become boolean properties as in the following example.

enableStartTLS=true

If you use a properties file with multiple tools, prefix the property name with the tool name followed by a dot (.), as in the following example.

setup.rootUserPasswordFile=/tmp/pwd.txt

The following steps demonstrate use of a properties file as part of a scripted installation process.

  1. Prepare your properties file.

    This procedure uses the following example properties file.

    #
    # Sample properties file to set up OpenDJ directory server
    #
    hostname                        =opendj.example.com
    ldapPort                        =1389
    generateSelfSignedCertificate   =true
    enableStartTLS                  =true
    ldapsPort                       =1636
    jmxPort                         =1689
    adminConnectorPort              =4444
    rootUserDN                      =cn=Directory Manager
    rootUserPassword                =password
    baseDN                          =dc=example,dc=com
    ldifFile                        =/net/install/dj/Example.ldif
    #sampleData                     =2000

    If you have multiple servers to install, consider scripting creation of the properties files.

  2. Prepare an installation script.

    $ cat /net/install/dj/1/setup.sh
    #!/bin/sh
    
    unzip -d /path/to /net/install/dj/OpenDJ-2.6.0.zip && cd /path/to/opendj
    ./setup --cli --propertiesFilePath /net/install/dj/1/setup.props \
      --acceptLicense --no-prompt
  3. Run your installation script.

    $ /net/install/dj/1/setup.sh
    Archive:  /net/install/dj/OpenDJ-2.6.0.zip
       creating: /path/to/opendj
    ...

    To see basic server configuration status and configuration you can launch
     /path/to/opendj/bin/status

    At this point you can use OpenDJ directory server, or you can perform additional configuration.

Procedure 2.6. To Install OpenDJ REST LDAP Gateway

The OpenDJ REST LDAP gateway functions as a web application in a web application container, running independently of OpenDJ. Alternatively, you can use the HTTP connection handler in OpenDJ directory server. See the procedure, To Set Up REST Access to OpenDJ Directory Server in the Administration Guide, for instructions.

You configure the gateway to access your directory service by editing opendj-rest2ldap-servlet.json where you deploy the gateway web application.

  1. Deploy opendj-rest2ldap-servlet-2.6.0-servlet.war according to the instructions for your application server.

  2. Edit opendj-rest2ldap-servlet.json where you deployed the gateway web application.

    The default JSON resource for the configuration includes both connection and authentication information, and also mappings. The mappings describe how the gateway translates between JSON and LDAP representations of your data. The default mappings are built to work with generated example data and also the sample content in Example.ldif.

    At minimum, make sure that the host name and port numbers for primaryLDAPServers are properly configured, that authentication reflects the correct simple bind credentials, and that the mappings for the endpoints correctly match your directory data.

    For details on the configuration, see REST LDAP Configuration in the Administration Guide.

  3. Restart the REST LDAP gateway or the application server to make sure the changes are taken into account.

  4. Make sure that your directory server is running, and then check that the gateway is connecting correctly.

    The following command reads Babs Jensen's entry through the gateway to the backend holding data from Example.ldif.

    $ curl http://bjensen:hifalutin@opendj.example.com:8080/rest2ldap/users/bjensen
     ?_prettyPrint=true
    {
      "_rev" : "000000002ee3b764",
      "schemas" : [ "urn:scim:schemas:core:1.0" ],
      "contactInformation" : {
        "telephoneNumber" : "+1 408 555 1862",
        "emailAddress" : "bjensen@example.com"
      },
      "_id" : "bjensen",
      "name" : {
        "familyName" : "Jensen",
        "givenName" : "Barbara"
      },
      "userName" : "bjensen@example.com",
      "displayName" : "Barbara Jensen",
      "manager" : [ {
        "_id" : "trigden",
        "displayName" : "Torrey Rigden"
      } ]
    }

    If you generated example data, Babs Jensen's entry is not included. Try a URL such as http://user.0:password@opendj.example.com:8080/rest2ldap/users/user.0 instead.

Procedure 2.7. To Install OpenDJ DSML gateway

The OpenDJ DSML gateway functions as a web application located in a web application container. The DSML gateway runs independently of OpenDJ directory server. You configure the gateway to access your directory service by editing the ldap.host and ldap.port parameters in the WEB-INF/web.xml configuration file.

  1. Deploy OpenDJ-2.6.0-DSML.war according to the instructions for your application server.

  2. Edit WEB-INF/web.xml to ensure the values for ldap.host and ldap.port are correct.

  3. Restart the web application container according to the instructions for your application server.

Chapter 3. Tuning JVM Options

By default, OpenDJ installs with options appropriate for evaluation, not for production.

You can change JVM options for the server in the QuickStart installer, and alternatively using the Control Panel (Runtime Options > Java Settings), or with the dsjavaproperties command after editing the config/java.properties file.

Heap size

The JVM heap size by default is either 256 MB or 1 GB.

In production, use at least a 2 GB heap (-Xms2G -Xmx2G).

Server optimizations

Use -server to select the HotSpot Server VM.

32-bit vs. 64-bit

For heap sizes over 4 GB on 64-bit systems use -d64.

Garbage collection

Use -XX:+UseConcMarkSweepGC to select the CMS garbage collector for low GC pause times.

New generation size

If your directory handles high throughput, set the new generation size large enough for the JVM to avoid promoting short-lived objects into the old gen space (-XX:NewSize=512M).

Chapter 4. Upgrading to OpenDJ 2.6.0

This chapter covers upgrade from OpenDJ 2.4.5 and later versions.

For upgrades from earlier versions, upgrade first to at least OpenDJ 2.4.5, and then follow the procedures in this chapter. See Upgrading OpenDJ Directory Server in the OpenDJ Wiki for details on upgrading to OpenDJ 2.4.5 from earlier versions.

Procedure 4.1. Before You Upgrade
  1. Prepare to perform the upgrade procedure as the user who owns the OpenDJ server files.

    Make sure you have the credentials to run commands as the user who owns the server.

  2. Download OpenDJ software from one of the following locations.

    • The ForgeRock BackStage downloads page has the latest stable, supported release of OpenDJ and the other products from ForgeRock.

    • The Nightly Builds page posts links to the latest nightly builds of OpenDJ software. Note that these builds are the working version from the trunk and are not for use in a production environment.

    • The Community Archives page includes stable community builds for previous releases of OpenDJ software.

  3. In order to revert if the upgrade fails, make sure you perform a full backup of your current OpenDJ installation.

    It might be most expedient to back up the file system directory where the current OpenDJ server is installed as part of the upgrade process.

    Alternatively, see Backing Up & Restoring Data in the Administration Guide for instructions.

Procedure 4.2. To Upgrade an OpenDJ Directory Server

To upgrade OpenDJ directory server installed from native packages (.deb, .rpm), use the command-line package management tools provided by the system.

The following steps describe how to upgrade OpenDJ directory server installed from the cross-platform (.zip) delivery.

  1. Login as the user who owns the current OpenDJ server.

  2. Stop the current OpenDJ server.

  3. (Optional) If you have not already backed up the current OpenDJ server, make a back up copy of the directory where OpenDJ is installed.

  4. (Optional) If OpenDJ is currently installed in a directory such as OpenDJ-2.4.5, you can change the directory name to opendj to make it easier to unpack subsequent .zip deliveries for future upgrades.

  5. Unpack the new files from the .zip delivery over the current server files.

    If your directory is not named opendj, then you can first unpack the files, then copy everything in the opendj over the current server files.

  6. Run the upgrade command to bring OpenDJ configuration and application data up to date with the new binary and script files that you copied over the current server files.

    By default, the upgrade command requests confirmation before making important configuration changes. You can use the --no-prompt option to run the command non-interactively, with the --acceptLicense option to accept the license terms non-interactively.

    When using the --no-prompt option, if the upgrade command cannot complete because it requires confirmation for a potentially very long or critical task, then it exits with an error and a message about how to finish making the changes. You can add the --force option to force a non-interactive upgrade to continue in this case, also performing long running and critical tasks.

  7. When you upgrade from OpenDJ 2.5.0-Xpress1, you must rebuild the ds-sync-hist ordering index before you restart the server.

    When upgrading to OpenDJ 2.6.1 and later, you no longer need to perform this step.

    This is indicated in the message from the upgrade tool:

      OpenDJ 2.5.0-Xpress1 introduced a regression in the ds-sync-hist ordering
      index. This index must be rebuilt after the upgrade has completed and before
      restarting OpenDJ. Do you wish to continue? (yes/no) [no]: yes

    To rebuild the index, use the rebuild-index command after upgrade but before starting the server as in the following example.

    $ ./opendj/bin/rebuild-index --baseDN dc=example,dc=com --index ds-sync-hist
    ... msg=Rebuild of index(es) ds-sync-hist started ...
    ... msg=Rebuild complete. Processed XXX entries in YYY seconds...
  8. Start the upgraded OpenDJ server.

    At this point the upgrade process is complete. See the resulting upgrade.log file for a full list of operations performed.

Example 4.1. Upgrading From OpenDJ 2.4.5

The following example upgrades an OpenDJ 2.4.5 directory server installed in /path/to/OpenDJ-2.4.5, backing up the current server directory in case the upgrade process fails, and changing the directory name to /path/to/opendj to simplify future upgrades.

$ cd /path/to
$ ls
OpenDJ-2.4.5
$ ./OpenDJ-2.4.5/bin/stop-ds --quiet
... msg=The backend userRoot is now taken offline
... msg=The Directory Server is now stopped
$ zip -rq OpenDJ-backup.zip OpenDJ-2.4.5
$ unzip -q ~/Downloads/OpenDJ-2.6.0.zip
$ cp -r opendj/* OpenDJ-2.4.5/
$ rm -rf opendj
$ mv OpenDJ-2.4.5 opendj
$ ./opendj/upgrade --no-prompt --acceptLicense
