Horton Works – Assign Static IP to HDP Sandbox V2.X in vSphere 6.X

April 2, 2018

HWX-RGB-full-w-tagline

I downloaded the HDP Sandbox 2.6 and tried to install it in vSphere. After making and breaking the file .ova file and finally deploying it;the machine got up but with network issues. To give your appliance a static IP address you will have to edit the networking scripts and reboot the machine. First of all verify your NIC instance with the following command (ens32 in my case).

ip addr show

01

The scripts can be found in the following location.

cd /etc/sysconfig/network-scripts

02

Evidently a script in my NIC instance name was missing.  I copied the contents of the already provided script (ifcfg-ens33) into a new file in my NIC instance name and modified the parameters to give a static IP to my sandbox instance.

vi ifcfg-ens32

03

BOOTPROTO=static

IPADDR=172.X.X.X.

NETMASK=255.255.255.0

GATEWAY=172.X.X.X

04

Save the file and reboot your appliance.

# reboot

After the reboot; the script assigned the static IP to the NIC instance and the Ambari server was up and running.

vSphere Design Pocket Book

Came across this eBook today and finished it reading almost two times on the go. Its basically a combination of tweets by VMware tech evangelists/experts giving away some very valuable tips and tricks on ESXi, vSphere, clustering, hardware considerations and resource allocation. I surely will start to follow these guide lines for my data-center. Thanks to PernixData; its available as a free download. You can access it here.

 

SQL Database Creation for vCenter 5.1 and vCenter Single Sign On 5.1

May 17, 2013

I am not a database guy and always have avoided anything related to it. When installing VMware vCenter 5.1 or earlier; you are prompted to create a DB instance. You can carry on by creating a default instance of SQL Express (zero effort required; YES I have always done that). But doing so is not recommended in a production environment as the DB gets populated and there are limited options to purge/protect your logs. Hence installation of separate SQL server is recommended. For a dumb person like me VMware is kind enough to include scripts for the DB creation and permission rights are available in the setup package but I found that customization was required. Hence for all the linked-minded fellows out there; this post might be of some help.

There are basically two DB’s needed to be created. One for the vCenter and other for the vCenter Single Sign On (SSO). VMware has made a major change in vCenter 5.1 for with its mandatory to install the SSO module.

I used Microsoft SQL Server 2008 (Enterprise Edition) to carry on my installation. For the basic requirement; select the following features:

  • Database Engine Services.
  • Client Tools Connectivity.
  • Integration Services.
  • Management Tools Basic/Complete

Once installed. Open the SQL Database Enterprise Manager and create a New Query. Execute the following three scripts one by one. (WordPress wont let me upload .sql or .txt files hence bear with .doc extension 🙂 )

  1. VCENTER_DB_CREATION_SCRIPT
  2. SSO_RSA_DB_CREATION_SCRIPT_1
  3. SSO_RSA_DB_CREATION_SCRIPT_2

Once done with this; make sure to create the ODBC SYSTEM DSN for the vCetner DB (VCDB). Following are the steps to create the SYSTEM DSN.

  1. Go to ODBC DATA SOURCE ADMINISTRATOR from the Control Panel. Click the SYSTEM DSN tab from the top. Click ADD.DSN 01
  2. Double click SQL NATIVE CLIENTDSN 02
  3. Enter the NAME for the data source and the IP of the DB Server. Click NEXTDSN 03
  4. Select the SQL SERVER AUTHENTICATION OPTION and give the user (default: vpxuser) credentials (you provided in VCENTER_DB_CREATION_SCRIPT). Click NEXTDSN 04
  5. Make sure that VCDB database is selected in the CHANGE THE DEFAULT DATABASE TO tab. Click NEXTDSN 05
  6. Leave the default settings and click FINISHDSN 06
  7. You can verify your DB connectivity by clicking TEST DATA SOURCEdsn-07

DSN 08

After doing this; you can now proceed with your vCenter installation. Start the installation by clicking the vCenter Server Simple Install from the vCenter Setup Wizard.

During the SSO installation you will be asked to provide the DB details as illustrated below.  Provide the credentials you created in script SSO_RSA_DB_CREATION_SCRIPT_2.

Single Sign On 01

When the SSO and vCenter inventory setups get completed; the installation for the vCenter Server will begin. During the setup you will be again asked to provide the DB details. Select the radio tab for USE AN EXISTING SUPPORTED DATABASE and select the already created SYSTEM DSN (VCDB).  Make sure to enter the credentials you entered while you creating the SYSTEM DSN.

VCENTER 01

VCENTER 02

Thats all you need to configure the DB’s for your vCenter installation. I am personally done with my installation but now am stuck on a couple of up-gradation issues from 5.0 to 5.1. Hence in my next blog I will be writing on those issues.
