[Tutorial] Deploying VMware vCloud Director 5.5

Here are some notes on deploying VMware vCloud Director 5.5.  I fealt the process as a whole was very confusing as there really isn't a definitive guide out there for folks going from vCenter to a suite product such as vCloud Director.

Prerequisites / Tutorial To-Do List

  • Microsoft SQL Server 2008 R2
    • The SQL Server must use Mixed Mode authentication (cannot use Windows Authentication, must be a SQL account)  We'll go over configuring this in the guide.
  • Linux VM
    • Must run one of the following OSes (I'm using CentOS6 for this guide)
      • CentOS 6 (64-bit) Update 4
      • Red Hat Enterprise Linux 5 (64-bit) Update 4
      • Red Hat Enterprise Linux 5 (64-bit) Update 5

      • Red Hat Enterprise Linux 5 (64-bit) Update 7
      • Red Hat Enterprise Linux 5 (64-bit) Update 8
      • Red Hat Enterprise Linux 5 (64-bit) Update 9
      • Red Hat Enterprise Linux 6 (64-bit) Update 1
      • Red Hat Enterprise Linux 6 (64-bit) Update 2
      • Red Hat Enterprise Linux 6 (64-bit) Update 3
      • Red Hat Enterprise Linux 6 (64-bit) Update 4
    • Two network adapters
    • At least 4 GB of memory
    • Hard drive space for the OS and an additional 2 GB of disk space for vmware installation and log files
  • Working ESXi environment with vCenter Server
  • VMware vCloud Networking and Security 5.5.x
  • VMware vCloud Director License Key

Deploy VMware vCloud Networking and Security 5.5.x 

Prior to installing vCloud Director, you must have the VMware vCloud Networking and Security 5.5.x appliance configured and running.  This product was formally called vShield, as is a required component of vCloud Director.  Instructions on how to deploy this can be found here: http://jackstromberg.com/2014/04/tutorial-deploying-vmware-vcloud-networking-and-security-5-5/

Linux VM Installation (CentOS 6)

  1. Grab a copy of the live CD iso to install the OS
    1. http://isoredirect.centos.org/centos/6/isos/x86_64/
  2. Next your way to victory through the install, substituting in your location and server info.
  3. Install VM tools once you have your OS up and running
    1. Tutorial on how to install VMtools on CentOS 6 can be found here: http://jackstromberg.com/2014/04/tutorial-how-to-install-vmtools-on-centos-6/
  4. Configure static IPs on each of your network cards
  5. Enable the firewall to allow inbound connections on port 443 (HTTPS)
    1. Tutorial on how to add firewall rules to CentOS 6 can be found here: http://jackstromberg.com/2014/04/tutorial-adding-firewall-rules-via-system-config-firewall-tui-on-centos-6/

Generate SSL certificates

We will need to generate some SSL certificates before running the vCloud Director installation.  Please follow the steps below to create a java keystore that vCloud director will use for SSL.  Below are two different methods of generating certificates.  Use the first if you don't want to sign your certificates, use the second if you want to sign your certificate with an internal or external certificate authority.  Note: Usually I create seperate keystores with for each service, in this case, VMware wants both certificates in the same keystore.  Additionally, make sure you change the default password in the commands below to something stronger (other VMware products want you to use a generic password, this one you can change as it will be prompted during the install process).

Creating Self-Signed Certificates

keytool -genkey -keyalg RSA -storetype JCEKS -alias http -keystore certificates.ks -storepass passwd -validity 360 -keysize 2048
Self-Signed vCloud Director Certificate - http

keytool -genkey -keyalg RSA -storetype JCEKS -alias consoleproxy -keystore certificates.ks -storepass passwd -validity 360 -keysize 2048
Self-Signed vCloud Director Certificate - consoleproxy

--Verify both certificates are in the same keystore--

keytool -list -keystore certificates.ks -storetype JCEKS -storepass "passwd"
Self-Signed vCloud Director Certificate - keystore

Creating Signed Certificate Requests (use this if you have an internal PKI, skip this step if you used self-signed certs above)

--Create the certificate requests--

  • HTTP Web Cert Request
    • keytool –certreq -keystore certificates.ks -storetype JCEKS -storepass passwd -alias http -file http.csr -validity 360 -keysize 2048
  • Console Proxy Cert Request
    • keytool -keystore certificates.ks -storetype JCEKS -storepass passwd -certreq –alias consoleproxy -file consoleproxy.csr -validity 360 -keysize 2048

--Import CA Chain--

  • Root Certificate Authority
    • keytool -storetype JCEKS -storepass passwd -keystore certificates.ks -import –alias root -file root.cer
  • Intermediate Certificate Authority (only needed if you have one)
    • keytool -storetype JCEKS -storepass passwd -keystore certificates.ks -import –alias intermediate -file intermediate.cer

--Import Signed Cert--

  • HTTP Web Signed Cert
    • keytool -storetype JCEKS -storepass passwd -keystore certificates.ks -import –alias http -file http.cer
  • Console Proxy Signed Cert
    • keytool -storetype JCEKS -storepass passwd -keystore certificates.ks -import –alias consoleproxy -file consoleproxy.cer

Configure the Microsoft SQL (MSSQL) Server Database

  1. Login to your SQL Server/Cluster
  2. Right click on your SQL Server and select Properties
    msSQL - Server Properties
  3. Select the Security page and ensure SQL Server and Windows Authentication mode is checked
    1. Per VMware's documentation, Windows Authentication is not supported when using Microsoft SQL with vCloud Director.
      Server Properties - SQL Server and Windows Authentication Mode
  4. Click OK
  5. Click on the New Query button and Execute the following query (make sure you change the path to the database and log files). This command will create the database instance and log files, specifying the proper collation sequence:
    USE [master]
    GO
    CREATE DATABASE [vcloud] ON PRIMARY
    (NAME = N'vcloud', FILENAME = N'C:\vcloud.mdf', SIZE = 100MB, FILEGROWTH = 10% )
    LOG ON
    (NAME = N'vcdb_log', FILENAME = N'C:\vcloud.ldf', SIZE = 1MB, FILEGROWTH = 10%)
    COLLATE Latin1_General_CS_AS
    GO
    msSQL - vCloud Director - Database Creation
  6. Use VMware's recommended transaction isolation level.  Click the New Query button again and then Execute the following query:
    USE [vcloud]
    GO
    ALTER DATABASE [vcloud] SET SINGLE_USER WITH ROLLBACK IMMEDIATE;
    ALTER DATABASE [vcloud] SET ALLOW_SNAPSHOT_ISOLATION ON;
    ALTER DATABASE [vcloud] SET READ_COMMITTED_SNAPSHOT ON WITH NO_WAIT;
    ALTER DATABASE [vcloud] SET MULTI_USER;
    GO
    msSQL - vCloud Director - Transaction Isolation Level
  7. Next, create the SQL User to connect to the database (we will use vcloud as the username, you can change this if you would like).  Click the New Query button again and then Execute the following query (amke sure to change the default password):
    USE [vcloud]
    GO
    CREATE LOGIN [vcloud] WITH PASSWORD = 'vcloudpass', DEFAULT_DATABASE =[vcloud],
    DEFAULT_LANGUAGE =[us_english], CHECK_POLICY=OFF
    GO
    CREATE USER [vcloud] for LOGIN [vcloud]
    GO
    msSQL - vCloud Director - Create User Account
  8. Last, assign the proper permissions to the SQL user.  We will need the user to have db_owner permissions for the install.  Click the New Query button again and then Execute the following query:
    USE [vcloud]
    GO
    sp_addrolemember [db_owner], [vcloud]
    GO
    msSQL - vCloud Director - db_owner privileges

The official VMware KB article on configuring MSSQL Server (and oracle) can be found here: http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=2034540

Configuring vCloud Director

  1. Open up your web browser and navigate over to your vCloud instance
  2. Optionally, install the VMware Remote Console Plug-in if prompted and then click Next
    1. The VMware Remote Console plug-in is used to manage your VMs through the web.  It is not needed during the installation process.
      vCloud Director - Setup Wizard - Welcome
  3. "Read" and check Yes, I accept the terms in the license agreement and click Next
    vCloud Director - Setup Wizard - License Agreement
  4. Enter your vCloud Director license key (can be obtained my myvmware.com) and click Next
    vCloud Director - Setup Wizard - Licensing
  5. Enter in an administrator account used to manage vCloud Director and then click Next
    vCloud Director - Setup Wizard - Create an Administrator Account
  6. Enter a system name (I used vCloudDirector) that gets added to vSphere.  This is where all the vCloud Director VMs will go when they are provisioned.  Click Next
    vCloud Director - Setup Wizard - System Settings
  7. Click Finish
    vCloud Director - Setup Wizard - Ready to Complete
  8. Login using your Administrator account once redirected
  9. Click on Attach a vCenter undernetth provision your Cloud resources...
    vCloud Director - Attach a vCenter
  10. Enter in your vCenter info and click Next
    vCloud Director - Attach a vCenter - Name this vCenter
  11. Enter in the username and password to your vShield Manager instance and click Next
    vCloud Director - Connect to vShield Manager
  12. Verify your settings and click Finish
    vCloud Director - Connect to vShield Manager - Ready to Complete
  13. Click on Step 2, Create a Provider VDC
    vCloud Director - Create Provider VDC
  14. If you have different resource pools with different configurations, I would create a similar name for your vDC.  In this example, I only have one resource pool containing all the resources in my environment, so I am going to name my vDC (Virtual Data Center) My Company.  Click Next when ready to proceed.
    1. Additionally, you can select what supported hardware version you wish to use.  As I have no ESX 4.x hosts, I am going to select Hardware version 9 as I have a newer environment.
    2. Note: Per VMware's website, here is the definition of a Provider vDC: A Provider vDC is a collection of compute, memory, and storage resources from one vCenter. A Provider vDC provides resources to organization vDCs.
      vCloud Director - Create Provider VDC - Name this Provider VDC
  15. Select a resource pool you wish to deploy the VMs to and click Next
    vCloud Director - Create Provider VDC - Select a Resource Pool
  16. If you have a specific datastore or storage policy you wish to use for this vDC, select the Storage Policy/Datastore, click the Add button, and then click Next.
    vCloud Director - Create Provider VDC - Select a Resource Pool - Add
  17. Enter in the credentials to each of the hosts to deploy the vCloud Director agent.  Once completed, click Next.
    vCloud Director - Create Provider VDC - Prepare Hosts
  18. Click Finish if the provided information looks correct
    vCloud Director - Create Provider VDC - Ready to Complete
  19. Now, depending on your configuration, if you had other VMs deployed to this resource pool, you may receive an error stating that the machines cannot enter maintennace mode.  The reason behind this is that DRS is preventing the hosts from entering maintnenace mode because DRS cannot move the VMs around to achieve High Availablity.
    vCloud Director - vCenter - Operation timed out - Prepare Host

    1. If you see this behavior, you will have to manually deploy the vCloud Director agents to the hosts.  To do this, click on the Manage & Monitor tab inside of vCloud Director.
      vCloud Director - Manage & Monitor
    2. Select Hosts
    3. Right click on one of the hosts and select Prepare Host...
      vCloud Director - Manage & Monitor - Prepare Host
    4. Enter the username and password to the host and click OK
      vCloud Director - Manage & Monitor - Prepare Host - Credentials
    5. Repeat this process for the other hosts in your cluster (you can select multiple hosts at a time. Now that we have at least one host available, we can failover a few VMs via)
      vCloud Director - Manage & Monitor - Prepare Host - Success
      vCloud Director - Manage & Monitor - Prepare Host - Success All Hosts
  20. Click on the Home tab and then click on the Create a new organization link
    vCloud Director - Create a new organization
  21. Enter in your organization information and click Next
    1. The Organization name is simply a code used to generate a short url to identify the organization.  Only letters and numbers are accepted in this field.
      vCloud Director - Create a new organization - Name this Organization
  22. Optionally select whether you want to use LDAP to provide access to vCloud Director and then click Next.
    vCloud Director - Create a new organization - LDAP Options
  23. On the Add Local Users page, click Add to add virtual vCloud Users (non-ldap).  Click Next once you have added the users of your choice or click Next if you want to add users later.
    vCloud Director - Create a new organization - Add Local Users
  24. On the Catalog page, select whether or not you want to allow sharing/publishing between organizations.  In this case, just click Next.
    (oops, no picture for this one 🙁 )
  25. On the Email Preferences page, click Next
    vCloud Director - Create a new organization - Email Preferences
  26. Configure the policies to your liking.  In this case I am going to leave things with their default settings and click Next
    (Oops, no picture for this one 🙁 )
  27. Click Finish
    vCloud Director - Create a new organization - Ready to Complete
  28. Click on Step 6 Allocate resources to an organization
    vCloud Director - Allocate resources to an organization
  29. Select the Organization you created and click Next
    vCloud Director - Allocate resources to an organization - Select Organization
  30. Select your Provider VDC and click Next
    vCloud Director - Allocate resources to an organization - Select Provider VDC
  31. Select the allocation model you choose to best fit your organization.  In this case, I am going to use Pay-As-You-Go to only allocate used resources.  Click Next.
    vCloud Director - Allocate resources to an organization - Select Allocation Model
  32. Choose you you want to configure your allocation model from the previous step and click Next.
    vCloud Director - Allocate resources to an organization - Configure Pay-As-You-Go Model
  33. Select the storage you want to use, click Add, and then click Next
    vCloud Director - Allocate resources to an organization - Allocate Storage
  34. Click Next on the Select Network Pool & Services page
    vCloud Director - Allocate resources to an organization - Select Network and Services
  35. Click Next if you don't need an edge gateway to an external network
    1. An edge gateway is needed to provide access to other internal and external (internet) networks.
      vCloud Director - Allocate resources to an organization - Create a new edge gateway
  36. Enter a name for the new Organization VDC and click Next
    vCloud Director - Allocate resources to an organization - Name this Organization VDC
  37. Click Finish
    vCloud Director - Allocate resources to an organization - Ready to Complete

At this point you should be able to publish a catalog or create a new VM from scratch in a completely isolated environment.  You can add an external network or utilize a VXLAN with additional configurations to begin to connect your network to an outside world.

Hope this helps!

Set static IP on CentOS 6 via command line

Here is how to configure a static IP on CentOS 6 via command line.

  1. Determine which interface you want to configure--in this example, I will be using eth0
    1. ifconfig -a
    2. Show all linux interfaces
  2. Edit the interface you wish to configure (I'll use nano as vi requires some knowledge for beginner Linux users)
    1. nano /etc/sysconfig/network-scripts/ifcfg-eth0
    2. nano ifcfg-eth0
  3. Use the following settings and then use Control+O to Save and Control+X to Exit
    1. nano /etc/sysconfig/network-scripts/ifcfg-eth0
    2. DHCPCLASS=
      IPADDR=192.168.1.100
      NETMASK=255.255.255.0
      ONBOOT=yes
      BOOTPROTO=STATIC
    3. static IP CentOS
  4. Next, let's configure the hostname and default gateway.  We will use nano again to edit the file.
    1. nano /etc/sysconfig/network
    2. Ensure GATEWAY=192.168.1.1 has been set
    3. Static Gateway
  5. Next, let's configure our DNS servers to resolve domain names (in this case, I will set mine to use Google's DNS servers)
    1. nano /etc/resolv.conf
    2. nameserver 8.8.8.8
      nameserver 8.8.4.4
    3. static nameservers
  6. Restart the networking service for the changes to take effect
    1. /etc/init.d/network restart
    2. restart interface
