How to Install OpenDJ on Arch Linux

OpenDJ is a high-performance LDAP directory service that is easy to install and configure. In this tutorial, we will guide you through the installation process of OpenDJ on Arch Linux.

Prerequisites

Before installing OpenDJ on Arch Linux, make sure that you have the following prerequisites installed:

• Arch Linux operating system
• Java Development Kit 8 or later
• Root privileges

Step 1: Download OpenDJ

To download OpenDJ, visit the download page at http://opendj.forgerock.org/downloads.html and select the latest version of OpenDJ. Alternatively, you can download the OpenDJ zip file using wget:

wget https://github.com/OpenIdentityPlatform/OpenDJ/releases/download/4.2.0/opendj-4.2.0.zip

Step 2: Extract OpenDJ

Once you have downloaded the OpenDJ zip file, extract it to a directory of your choice. You can use the unzip command to extract the OpenDJ zip file:

unzip opendj-4.2.0.zip

Step 3: Configure OpenDJ

Before starting OpenDJ, you need to configure it by running the configure command from the bin directory of the OpenDJ installation:

cd opendj-4.2.0/bin
./configure

Follow the prompts to configure the OpenDJ instance. You will be asked to provide a password for the administrator account, the base DN for the directory, and various other settings.

Step 4: Start OpenDJ

To start OpenDJ, run the following command:

./start-ds

You should see output similar to the following:

[22/Apr/2021:16:25:15 +0000] category=JVM severity=INFO msgID=org.opends.messages.runtime:137 msg=The JVM has started successfully.
[22/Apr/2021:16:25:16 +0000] category=PROTOCOL severity=NOTICE msgID=org.opends.messages.protocol:5095 msg=The Directory Server has started listening for LDAP requests on all network interfaces.
[22/Apr/2021:16:25:16 +0000] category=PROTOCOL severity=NOTICE msgID=org.opends.messages.protocol:5094 msg=The Directory Server has started listening for LDAPS requests on all network interfaces.

Step 5: Verify OpenDJ Installation

To verify that OpenDJ is running, you can use the following command to connect to the directory using LDAP:

ldapsearch -h localhost -p 1389 -D "cn=Directory Manager" -w password -b "dc=example,dc=com" "(objectclass=*)"

Replace the -D option with the DN of your administrator account, the -w option with its password and the -b option with the base DN of your directory.

If everything is working correctly, you should see output similar to the following:

# extended LDIF
#
# LDAPv3
# base <dc=example,dc=com> with scope subtree
# filter: (objectclass=*)
# requesting: ALL
#

# example.com
dn: dc=example,dc=com
objectClass: top
objectClass: domain
dc: example

# admin
dn: cn=admin,dc=example,dc=com
objectClass: simpleSecurityObject
objectClass: organizationalRole
cn: admin
