  4. Configure the rule.

    1. Select Rule  Custom TCP Rule.

    2. Select Direction  Ingress.

    3. Select Port from the Open Port list.

    4. Specify 443 in the Port field.

    5. Select CIDR from the Remote list.

    6. Specify 0.0.0.0/0 in the CIDR field.

    7. Click Add.

1.4. Creating a Custom Flavor

A flavor is a resource allocation profile that specifies, for example, how many virtual CPUs and how much RAM can be allocated to an instance. You can, for example, run ManageIQ on a Red Hat OpenStack m1.large flavor, which specifies a virtual machine with 4 cores, 12 GB RAM, and 80 GB disk space. Creating a flavor to run ManageIQ is optional.

The following procedure demonstrates creating a flavor with the minimum requirements (4 cores, 12 GB RAM, 44 GB disk space) for ManageIQ. For more information about flavors, see the Red Hat OpenStack Platform Administration User Guide.

  1. Log in to the OpenStack dashboard as admin.

  2. In the Admin tab, navigate to System  Flavors.

  3. Click Create Flavor to display the Create Flavor dialog.

  4. Configure the settings to define a flavor that meets ManageIQ system requirements.

    1. Enter a name for the flavor.

    2. Enter the following settings:

      • VCPUs: 4

      • RAM MB: 12288

      • Root Disk GB: 45

      • Ephemeral Disk GB: 0

      • Swap Disk MB: 0

  5. Click Create Flavor.

A new flavor specific to ManageIQ is created.

1.5. Launching the Instance

  1. From the OpenStack dashboard, navigate to Project  Compute  Instances.

  2. Click Launch Instance.

  3. Enter a name for the instance.

  4. Select the custom flavor for your instance. The flavor selection determines the computing resources available to your instance. The resources used by the flavor are displayed in the Flavor Details pane.

  5. Enter 1 in the Instance Count field.

  6. Select a boot option from the Instance Boot Source list:

    • Boot from image - displays a new field for Image Name. Select the image from the drop-down list.

    • Boot from snapshot - displays a new field for Instance Snapshot. Select the snapshot from the drop-down list.

    • Boot from volume - displays a new field for Volume. Select the volume from the drop-down list.

    • Boot from image (creates a new volume) - boot from an image and create a volume by choosing Device Size and Device Name for your volume. Some volumes can be persistent. To ensure the volume is deleted when the instance is deleted, select Delete on Terminate.

    • Boot from volume snapshot (creates a new volume) - boot from volume snapshot and create a new volume by choosing Volume Snapshot from the drop-down list and adding a Device Name for your volume. Some volumes can be persistent. To ensure the volume is deleted when the instance is deleted, select Delete on Terminate.

  7. Click Networking and select a network for the instance by clicking the + (plus) button for the network from Available Networks.

  8. Click Launch.

1.6. Adding a Floating IP Address

When you create an instance, Red Hat OpenStack Platform automatically assigns it a fixed IP address in the network to which the instance belongs. This IP address is permanently associated with the instance until the instance is terminated.

In addition to the fixed address, you can also assign a floating IP address to an instance. Unlike fixed IP addresses, you can modify floating IP addresses associations at any time, regardless of the state of the instances involved.

  1. At the command-line on your RHEL OpenStack Platform host, create a pool of floating IP addresses using the nova-manage floating create command. Replace IP_BLOCK with the desired block of IP addresses expressed in CIDR notation.

    $ nova-manage floating create IP_BLOCK

  2. In the Project tab, navigate to Compute  Access & Security.

  3. Click Floating IPs  Allocate IP To Project. The Allocate Floating IP window is displayed. 7218

  4. Click Allocate IP to allocate a floating IP from the pool. The allocated IP address appears in the Floating IPs table.

  5. Select the newly allocated IP address from the Floating IPs table. Click Associate to assign the IP address to a specific instance. 7217

  6. Select an instance with which to associate the floating IP Address.

  7. Click Associate to associate the IP address with the selected instance.

To disassociate a floating IP address from an instance when it is no longer required, click Release Floating IPs.

2. Configuring ManageIQ

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

  1. Add a disk to the infrastructure hosting your appliance.

  2. Configure the database.

Configure the ManageIQ 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 ManageIQ 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.

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

2.2. 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 ManageIQ 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 ManageIQ 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.

    All ManageIQ 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.

3. Logging In After Installing ManageIQ

Once ManageIQ is installed, you can log in and perform administration tasks.

Log in to ManageIQ 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 ManageIQ.

  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.
