# Chapter 1. Installing Red Hat CloudForms

Installing Red Hat CloudForms consists of the following steps:

2. Creating a blank VHD to be used for the database disk.
3. Running a PowerShell script to create a deployable template for the CloudForms appliance.
4. Configuring the CloudForms appliance.

After you have completed all the procedures in this guide, you will have a working environment on which you can perform additional customizations and configurations.

Requirements

• A Microsoft System Center Virtual Machine Manager environment with at least one Hyper-V node.
• 44 GB of storage space.
• 12 GB RAM.
• 4 vCPUs.
• An Admin privileged account for the SCVMM environment

## 1.1. Obtaining the Appliance

2. Navigate to the Red Hat Customer Portal Downloads page at access.redhat.com.
7. When the image finishes downloading, open a PowerShell terminal and run 'Refresh-LibraryShare':

PS C:\Users\Administrator.MS01> 'Refresh-LibraryShare'

## 1.2. Deploying the Appliance

Create a blank VHD to be used for the database disk and add it to your SCVMM Library, create a template for the CloudForms appliance, then deploy a virtual machine to run the appliance.

1. Create a blank VHD to be used for the database disk and add it to your SCVMM Library. Run this command on a node containing Hyper-V.

For example, on a node with Hyper-V installed you can create a 20GB blank VHD with the following PowerShell command:

PS C:\Users\Administrator.MS01> New-VHD -Path 'C:\path\to\my\newvdisk.vhdx' -SizeBytes 20gb -Dynamic
2. Copy the blank VHD disk to the SCVMM Library.
3. In a PowerShell terminal, run 'Refresh-LibraryShare' to refresh the library:

PS C:\Users\Administrator.MS01> 'Refresh-LibraryShare'
4. Run the following PowerShell script to create a deployable template for the CloudForms appliance, substituting values for your environment:

$networkName = "yourNetwork"$templateName = "myNewCFMETemplate"
$templateOwner = "ownerUsername"$memorySizeMb = 12288
$cpuCount = 4$srcPath = "C:\path\to\vhd\in\Library"
$dbDiskSrcPath = "C:\path\to\db\vhd\in\Library"$templateOsType = "Red Hat Enterprise Linux 7 (64 bit)"
$scvmmFqdn = "fqdn.of.scvmm.com"$JobGroupId01 = [Guid]::NewGuid().ToString()
$LogicalNet = Get-SCLogicalNetwork -Name$networkName
New-SCVirtualNetworkAdapter -JobGroup $JobGroupID01 -MACAddressType Dynamic -LogicalNetwork$LogicalNet -Synthetic
New-SCVirtualSCSIAdapter -JobGroup $JobGroupID01 -AdapterID 6 -Shared$False
New-SCHardwareProfile -Name $templateName -Owner$templateOwner
-Description 'Temp profile used to create a VM Template' -MemoryMB
$memorySize -CPUCount$cpuCount -JobGroup $JobGroupID01$JobGroupId02 = [Guid]::NewGuid().ToString()
$VHD = Get-SCVirtualHardDisk | where {{$_.Location -eq $srcPath }} | where {{$_.HostName -eq $scvmmFqdn }} New-SCVirtualDiskDrive -IDE -Bus 0 -LUN 0 -JobGroup$JobGroupID02
-VirtualHardDisk $VHD$DBVHD = Get-SCVirtualHardDisk | where {{ $_.Location -eq$dbDiskSrcPath }}
New-SCVirtualDiskDrive -IDE -Bus 1 -LUN 0 -JobGroup $JobGroupID02 -VirtualHardDisk$DBVHD
$HWProfile = Get-SCHardwareProfile | where {{$_.Name -eq $templateName }}$OS = Get-SCOperatingSystem | where {{ $_.Name -eq$templateOsType }}
New-SCVMTemplate -Name $templateName -Owner$templateOwner -HardwareProfile
$HWProfile  -JobGroup$JobGroupID02 -RunAsynchronously -Generation 1 -NoCustomization
Remove-HardwareProfile -HardwareProfile $templateName 5. Deploy a virtual machine to a host group from the created template. Run the following PowerShell script, substituting values for your environment: $tpl = Get-SCVMTemplate -Name $templateName -VMMServer$scvmmServer
$vm_hg = Get-SCVMHostGroup -Name$hostGroup -VMMServer $scvmmServer$vmc = New-SCVMConfiguration -VMTemplate $tpl -Name$vmName -VMHostGroup $vm_hg Update-SCVMConfiguration -VMConfiguration$vmc
New-SCVirtualMachine -Name $vmName -VMConfiguration$vmc
Note

Substitute these values in your PowerShell script:

• $hostGroup = "NAME_OF_HOST_GROUP_TO_DEPLOY_TO" •$scvmmServer = "NAME_OF_YOUR_SCVMM_SERVER"
• $templateName = "NAME_OF_CFME_TEMPLATE" •$vmName = "NAME_OF_YOUR_NEW_VM"

Your SCVMM environment now contains a running CloudForms appliance which you can configure.

# Chapter 2. Configuring Red Hat CloudForms

After installing CloudForms and running it for the first time, you must perform some basic configuration. To configure CloudForms, you must at a minimum:

2. Configure the database.

Configure the CloudForms appliance using the internal appliance console.

## 2.1. Accessing the Appliance Console

1. Start the appliance and open a terminal console.
2. After starting the appliance, log in with a user name of root and the default password of smartvm. This displays the Bash prompt for the root user.
3. Enter the appliance_console command. The Red Hat CloudForms appliance summary screen displays.
4. Press Enter to manually configure settings.
5. Press the number for the item you want to change, and press Enter. The options for your selection are displayed.
6. Follow the prompts to make the changes.
7. Press Enter to accept a setting where applicable.
Note

The CloudForms appliance console automatically logs out after five minutes of inactivity.

## 2.2. Configuring a Database

CloudForms uses a database to store information about the environment. Before using CloudForms, configure the database options for it; CloudForms provides the following two options for database configuration:

• Install an internal PostgreSQL database to the appliance
• Configure the appliance to use an external PostgreSQL database

### 2.2.1. Configuring an Internal Database

Important

Before installing an internal database, add a disk to the infrastructure hosting your appliance. See the documentation specific to your infrastructure for instructions for adding a disk. As a storage disk usually cannot be added while a virtual machine is running, Red Hat recommends adding the disk before starting the appliance. Red Hat CloudForms only supports installing of an internal VMDB on blank disks; installation will fail if the disks are not blank.

1. Start the appliance and open a terminal console.
2. After starting the appliance, log in with a user name of root and the default password of smartvm. This displays the Bash prompt for the root user.
3. Enter the appliance_console command. The Red Hat CloudForms appliance summary screen displays.
4. Press Enter to manually configure settings.
5. Select 5) Configure Database from the menu.
6. You are prompted to create or fetch an encryption key.

• If this is the first Red Hat CloudForms appliance, choose 1) Create key.
• If this is not the first Red Hat CloudForms appliance, choose 2) Fetch key from remote machine to fetch the key from the first appliance. For worker and multi-region setups, use this option to copy key from another appliance.

Note

All CloudForms appliances in a multi-region deployment must use the same key.

7. Choose 1) Create Internal Database for the database location.
8. Choose a disk for the database. This can be either a disk you attached previously, or a partition on the current disk.

Important

Red Hat recommends using a separate disk for the database.

If there is an unpartitioned disk attached to the virtual machine, the dialog will show options similar to the following:

1) /dev/vdb: 20480
2) Don't partition the disk
• Enter 1 to choose /dev/vdb for the database location. This option creates a logical volume using this device and mounts the volume to the appliance in a location appropriate for storing the database. The default location is /var/opt/rh/rh-postgresql95/lib/pgsql, which can be found in the environment variable $APPLIANCE_PG_MOUNT_POINT. • Enter 2 to continue without partitioning the disk. A second prompt will confirm this choice. Selecting this option results in using the root filesystem for the data directory (not advised in most cases). 9. Enter Y or N for Should this appliance run as a standalone database server? • Select Y to configure the appliance as a database-only appliance. As a result, the appliance is configured as a basic PostgreSQL server, without a user interface. • Select N to configure the appliance with the full administrative user interface. 10. When prompted, enter a unique number to create a new region. Important Creating a new region destroys any existing data on the chosen database. 11. Create and confirm a password for the database. Red Hat CloudForms then configures the internal database. This takes a few minutes. After the database is created and initialized, you can log in to CloudForms. ### 2.2.2. Configuring an External Database Based on your setup, you will choose to configure the appliance to use an external PostgreSQL database. For example, we can only have one database in a single region. However, a region can be segmented into multiple zones, such as database zone, user interface zone, and reporting zone, where each zone provides a specific function. The appliances in these zones must be configured to use an external database. The postgresql.conf file used with Red Hat CloudForms databases requires specific settings for correct operation. For example, it must correctly reclaim table space, control session timeouts, and format the PostgreSQL server log for improved system support. Due to these requirements, Red Hat recommends that external Red Hat CloudForms databases use a postgresql.conf file based on the standard file used by the Red Hat CloudForms appliance. Ensure you configure the settings in the postgresql.conf to suit your system. For example, customize the shared_buffers setting according to the amount of real storage available in the external system hosting the PostgreSQL instance. In addition, depending on the aggregate number of appliances expected to connect to the PostgreSQL instance, it may be necessary to alter the max_connections setting. Note • Red Hat CloudForms 4.x requires PostgreSQL version 9.5. • Because the postgresql.conf file controls the operation of all databases managed by a single instance of PostgreSQL, do not mix Red Hat CloudForms databases with other types of databases in a single PostgreSQL instance. 1. Start the appliance and open a terminal console. 2. After starting the appliance, log in with a user name of root and the default password of smartvm. This displays the Bash prompt for the root user. 3. Enter the appliance_console command. The Red Hat CloudForms appliance summary screen displays. 4. Press Enter to manually configure settings. 5. Select 5) Configure Database from the menu. 6. You are prompted to create or fetch a security key. • If this is the first Red Hat CloudForms appliance, choose 1) Create key. • If this is not the first Red Hat CloudForms appliance, choose 2) Fetch key from remote machine to fetch the key from the first appliance. Note All CloudForms appliances in a multi-region deployment must use the same key. 7. Choose 2) Create Region in External Database for the database location. 8. Enter the database hostname or IP address when prompted. 9. Enter the database name or leave blank for the default (vmdb_production). 10. Enter the database username or leave blank for the default (root). 11. Enter the chosen database user’s password. 12. Confirm the configuration if prompted. Red Hat CloudForms will then configure the external database. ## 2.3. Configuring a Worker Appliance You can use multiple appliances to facilitate horizontal scaling, as well as for dividing up work by roles. Accordingly, configure an appliance to handle work for one or many roles, with workers within the appliance carrying out the duties for which they are configured. You can configure a worker appliance through the terminal. The following steps demonstrate how to join a worker appliance to an appliance that already has a region configured with a database. 1. Start the appliance and open a terminal console. 2. After starting the appliance, log in with a user name of root and the default password of smartvm. This displays the Bash prompt for the root user. 3. Enter the appliance_console command. The Red Hat CloudForms appliance summary screen displays. 4. Press Enter to manually configure settings. 5. Select 5) Configure Database from the menu. 6. You are prompted to create or fetch a security key. Since this is not the first Red Hat CloudForms appliance, choose 2) Fetch key from remote machine. For worker and multi-region setups, use this option to copy the security key from another appliance. Note All CloudForms appliances in a multi-region deployment must use the same key. 7. Choose 3) Join Region in External Database for the database location. 8. Enter the database hostname or IP address when prompted. 9. Enter the port number or leave blank for the default (5432). 10. Enter the database name or leave blank for the default (vmdb_production). 11. Enter the database username or leave blank for the default (root). 12. Enter the chosen database user’s password. 13. Confirm the configuration if prompted. # Chapter 3. Logging In After Installing Red Hat CloudForms Once Red Hat CloudForms is installed, you can log in and perform administration tasks. Log in to Red Hat CloudForms for the first time after installing by: 1. Navigate to the URL for the login screen. (https://xx.xx.xx.xx on the virtual machine instance) 2. Enter the default credentials (Username: admin | Password: smartvm) for the initial login. 3. Click Login. ## 3.1. Changing the Default Login Password Change your password to ensure more private and secure access to Red Hat CloudForms. 1. Navigate to the URL for the login screen. (https://xx.xx.xx.xx on the virtual machine instance) 2. Click Update Password beneath the Username and Password text fields. 3. Enter your current Username and Password in the text fields. 4. Input a new password in the New Password field. 5. Repeat your new password in the Verify Password field. 6. Click Login. # Appendix A. Appendix ## A.1. Appliance Console Command-Line Interface (CLI) Currently, the appliance_console_cli feature is a subset of the full functionality of the appliance_console itself, and covers functions most likely to be scripted using the command-line interface (CLI). 1. After starting the Red Hat CloudForms appliance, log in with a user name of root and the default password of smartvm. This displays the Bash prompt for the root user. 2. Enter the appliance_console_cli or appliance_console_cli --help command to see a list of options available with the command, or simply enter appliance_console_cli --option <argument> directly to use a specific option. Table A.1. Database Configuration Options OptionDescription --region (-r) region number (create a new region in the database - requires database credentials passed) --internal (-i) internal database (create a database on the current appliance) --dbdisk database disk device path (for configuring an internal database) --hostname (-h) database hostname --port database port (defaults to 5432) --username (-U) database username (defaults to root) --password (-p) database password --dbname (-d) database name (defaults to vmdb_production) Table A.2. v2_key Options OptionDescription --key (-k) create a new v2_key --fetch-key (-K) fetch the v2_key from the given host --force-key (-f) create or fetch the key even if one exists --sshlogin ssh username for fetching the v2_key (defaults to root) --sshpassword ssh password for fetching the v2_key Table A.3.
