1. Configuring ManageIQ

Although the ManageIQ appliance comes configured to be integrated immediately into your environment, you can make some changes to its configuration.

The ManageIQ appliance is intended to have minimal configuration options.

1.1. Changing Configuration Settings

The following procedure describes how to make changes to the configuration settings on the ManageIQ appliance.

  1. Start the appliance and open a terminal console.

  2. Log in to the appliance using the SSH key.

  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.

1.2. Advanced Configuration Settings

After logging in, you can use the following menu items for advanced configuration of the appliance:

  • Use Set DHCP Network Configuration to use DHCP to obtain the IP address and network configuration for your ManageIQ appliance. The appliance is initially configured as a DHCP client with bridged networking.

  • Use Set Static Network Configuration if you have a specific IP address and network settings you need to use for the ManageIQ appliance.

  • Use Test Network Configuration to check that name resolution is working correctly.

  • Use Set Hostname to specify a hostname for the ManageIQ appliance.

    A valid fully qualified hostname for the ManageIQ appliance is required for SmartState analysis to work correctly,

  • Use Set Timezone to configure the time zone for the ManageIQ appliance.

  • Use Set Date and Time to configure the date and time for the ManageIQ appliance.

  • Use Restore Database from Backup to restore the Virtual Management Database (VMDB) from a previous backup.

  • Use Setup Database Region to create regions for VMDB replication.

  • Use Configure Database to configure the VMDB. Use this option to configure the database for the appliance after installing and running it for the first time.

  • Use Configure Database Replication to configure a primary or standby server for VMDB replication.

  • Use Configure Database Maintenance to configure the VMDB maintenance schedule.

  • Use Configure Application Database Failover Monitor to start or stop VMDB failover monitoring.

  • Use Extend Temporary Storage to add temporary storage to the appliance. The appliance formats an unpartitioned disk attached to the appliance host and mounts it at /var/www/miq_tmp. The appliance uses this temporary storage directory to perform certain image download functions.

  • Use Configure External Authentication (httpd) to configure authentication through an IPA server.

  • Use Generate Custom Encryption Key to regenerate the encryption key used to encode plain text password.

  • Use Harden Appliance Using SCAP Configuration to apply Security Content Automation Protocol (SCAP) standards to the appliance. You can view these SCAP rules in the /var/www/miq/lib/appliance_console/config/scap_rules.yml file.

  • Use Stop EVM Server Processes to stop all server processes. You may need to do this to perform maintenance.

  • Use Start EVM Server Processes to start the server. You may need to do this after performing maintenance.

  • Use Restart Appliance to restart the ManageIQ appliance. You can either restart the appliance and clear the logs or just restart the appliance.

  • Use Shut Down Appliance to power down the appliance and exit all processes.

  • Use Summary Information to go back to the network summary screen for the ManageIQ appliance.

  • Use Quit to leave the ManageIQ appliance console.

1.3. Configuring a Database for ManageIQ

Before using ManageIQ, configure the database options for it. ManageIQ provides two options for database configuration:

  • Install an internal PostgreSQL database to the appliance

  • Configure the appliance to use an external PostgreSQL database

1.4. Configuring an Internal Database

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. ManageIQ 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. Log in to the appliance using the SSH key.

  3. Enter the appliance_console command. The ManageIQ appliance summary screen displays.

  4. Press Enter to manually configure settings.

  5. Select 8) Configure Database from the menu.

  6. You are prompted to create or fetch an encryption key.

    • If this is the first ManageIQ appliance, choose 1) Create key.

    • If this is not the first ManageIQ appliance, choose 2) Fetch key from remote machine to fetch the key from the first ManageIQ appliance. All ManageIQ appliances in a multi-region deployment must use the same key.

  7. Choose 1) Internal 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.

    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 Configure this server as a dedicated database instance?

    • Select Y to configure the appliance only as a database. 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.

    Creating a new region destroys any existing data on the chosen database.

  11. Create and confirm a password for the database.

ManageIQ then configures the internal database.

1.5. Configuring an External Database

The postgresql.conf file used with ManageIQ 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 ManageIQ databases use a postgresql.conf file based on the standard file used by the ManageIQ 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.

Because the postgresql.conf file controls the operation of all databases managed by a single instance of PostgreSQL, do not mix ManageIQ databases with other types of databases in a single PostgreSQL instance.

ManageIQ 4.x requires PostgreSQL version 9.4.

  1. Start the appliance and open a terminal console.

  2. Log in to the appliance using the SSH key.

  3. Enter the appliance_console command. The ManageIQ appliance summary screen displays.

  4. Press Enter to manually configure settings.

  5. Select 8) Configure Database from the menu.

  6. You are prompted to create or fetch a security key.

    • If this is the first ManageIQ appliance, select the option to create a key.

    • If this is not the first ManageIQ appliance, select the option to fetch the key from the first ManageIQ appliance. All ManageIQ appliances in a multi-region deployment must use the same key.

  7. Choose 2) External 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.

ManageIQ will then configure the external database.

1.6. Configuring a Worker Appliance

You can configure a worker appliance through the terminal. These 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. Log in to the appliance using the SSH key.

  3. Enter the appliance_console command. The ManageIQ appliance summary screen displays.

  4. Press Enter to manually configure settings.

  5. Select 8) Configure Database from the menu.

  6. You are prompted to create or fetch a security key. Select the option to fetch the key from the first ManageIQ appliance. All ManageIQ appliances in a multi-region deployment must use the same key.

  7. Choose 2) External 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.

2. 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.

2.1. 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.

Appendix A: Appendix
