Quick Installation Guide 

DDI Central for Linux DNS and DHCP servers 
ManageEngine DDI Central can be deployed as an overlay for your existing Linux DNS and DHCP clusters that runs on Internet Systems Consortium : ISC DHCP and ISC BIND9 DNS software. To successfully install DDI Central download the following .bin files: 

Management UI Console (ddiconsole.bin): The central console with a unified user interface where all the DNS, DHCP and IP configurations are consolidated, monitored, correlated and controlled from a single window. 

Discovery Node Agent (ddinodeagent.bin): A lightweight agent installed on all managed DNS and DHCP servers, which frequently communicates with the central console to provide continuous visibility. 

DDI Central for Microsoft DNS and DHCP servers 

DDI Central can also be deployed as an overlay for your existing Windows DNS and DHCP clusters that run on Microsoft Windows Server OS 2016, 2019, and 2022. For this download the .exe based installer available in our Downloads page. With this .exe installer you can create only Windows based DNS and DHCP servers and manage their configurations through DDI Central's intuitive UI.  For more 

Note: To manage both Linux and Windows based DNS and DHCP clusters directly from DDI Central's unified interface you can run DDI Central on your Linux machines by downloading the .bin files mentioned above.

DDI Central console mode installation 

Installing DDI Central Management UI Console 
Follow the instructions as they appear on the screen to successfully install DDI Central Management UI Console (ddiconsole.bin) on to any remote machine. This is a quick walk-through of the console mode installation of DDI on a Linux box - an easy thing to do if you are working on a Windows box and want to install on a remote Linux system. 

Step 1:Execute the binary with administrator privileges (sudo) and -i consoleoption.

Step 2:Go through the license agreement and enter 'Y' to proceed. You can register for technical support by providing the required details. (Name, E-mail ID, Phone, Company Name) 


Step 3:Select the location

Step 4:Choose the installation directory

 Step 5:Configure the Webserver and Listener Ports.

 Step 6:Verify the installation details and press 'Enter' to complete the installation.

i.e

During installation if you get an error message stating that the temp folder does not have enough space, try executing this command with the -is:tempdiroption, where is the absolute path of an existing directory.

./ManageEngine_DDI_xxxx.bin -is:tempdir

For non-x11 machines, use the following command:

./ManageEngine_DDIr_xxxx.bin -i console

Note: You can follow similar set of instructions as they appear on the screen to install DDI Central Discovery Node Agent (ddinodeagent.bin) on to any remote machine.  

Starting DDI Central 

Once the ManageEngine DDI Central installation is completed, you can start the service by executing following command on your linux box

systemctl start DDI

To check whether service is started, execute the following command:

systemctl status DDI

After ensuring service is started successfully, you can connect the web client using both http and https as follows

http://server_ip:9090

https://server_ip:9443

Accessing the Web Client 

Once the service has successfully started, follow the steps below to access DDI Central.

1. Open a  supported web browser window
2. Type the URL address as http://DDI_ConsoleServer_IP:9090(where DDI Console Server  is the name of the machine on whichDDI Console Serveris running, and 9090is the default web server port)
3. Log in to DDI using the default username/password combination of admin/admin

License components in DDI Central 

Clusters in ManageEngine DDI Central 

Clusters are logical groupings of servers - DNS, DHCP or both organized for identification and administrative purposes. These clusters operate independently of other clusters configured within DDI Central. Each cluster you add has its own internalized  IP address plans, IP inventory,  IP Address Manager, DNS manager and DHCP manager.

A single cluster can accommodate any number of DNS servers and DHCP servers. However, ManageEngine DDI Central enables you to add only one Primary DHCP server for each cluster and the rest of DHCP servers act secondary servers configured under DHCP failover configurations.

Essential Plan: 

The Essential plan includes  1DNS cluster and 1 DHCP cluster. You can add up to 3 DNS serversinto the DDI Central console. Similarly, the single DHCP cluster allows for the addition of up to 2 DHCP servers. 

These servers can be grouped together within a single cluster or distributed across multiple clusters in any combination as per your preference. There is no restriction on the number of clusters you can create and each cluster comes with an internalized IPAM that enables you to manage exclusive dual stack IP address spaces (IPv4 and IPv6) for the cluster. Along with this, you can manage 5 DNS Zones, 5 IP Subnet, and onboard one Admin/Operator user.

Professional Plan: 

The Professional plan provides 2 DNS clusters (6 DNS servers max) and 2 DHCP clusters (4 DHCP servers). This way you can add up to six DNS servers and four DHCP servers in total. You have the flexibility to organize these servers by grouping them into a single cluster or by creating multiple clusters. You can configure the clusters in any combination that suits your needs, with no limit on the number of clusters. Each cluster you create in DDI Central comes with an internalized IPAM enabling you to manage a separate dual stack IP address spaces for that cluster. In addition to this, you can also manage 15 DNS Zones, 15 IP Subnets, and onboard two Admin/ Operator users with relevant access permissions.

Note:You can also purchase additional DNS clusters, DHCP clusters, subnets, zones, and users as add-ons. Please refer the ManageEngine Storepage to check the prices of DDI Central add-ons.

Once installed, DDI Central runs in evaluation mode for 30 days. You can obtain a registered license for DDI Central at any time during the evaluation period by contacting DDI  Central Support. If you have not upgraded to the Licensed Edition by the end of the evaluation period, DDI Central evaluation license expires and you will have only read-only access.
