Configuring ManageIQ
After installing ManageIQ and running it for the first time, you must perform some basic configuration. You must complete these steps:
-
Add a disk to the infrastructure that is hosting your appliance.
-
Configure the database.
-
Configure messaging
Configure the appliance by using the internal appliance console.
Accessing the Appliance Console
-
Start the appliance and open a terminal console.
-
Enter the
appliance_console
command. The ManageIQ appliance summary screen displays. -
Press
Enter
to manually configure settings. -
Press the number for the item that you want to change, and press
Enter
. The options for your selection are displayed. -
Follow the prompts to make the changes.
-
Press
Enter
to accept a setting where applicable.
Note: The ManageIQ appliance console automatically logs out after five minutes of inactivity.
Configuring a Database
ManageIQ uses a database to store information about the environment. Before using ManageIQ, configure the database options for it; ManageIQ provides the following two options for database configuration:
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.
-
Start the appliance and open a terminal console.
-
Enter the
appliance_console
command. The ManageIQ appliance summary screen displays. -
Press Enter to manually configure settings.
-
Select Configure Application from the menu.
-
You are prompted to create or fetch an encryption key.
-
If this is the first ManageIQ appliance, choose Create key.
-
If this is not the first ManageIQ appliance, choose 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 ManageIQ appliances in a multi-region deployment must use the same key.
-
-
Choose Create Internal Database for the database location.
In the Configure Messaging menu, select Make No messaging changes. If you see
Configuration failed: Internal database require a volume mounted at /var/lib/pgsql. Please add an unpartitioned disk and try again.
message, then ensure to add a second disk for the database per instructions as defined above. -
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/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).
-
-
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.
-
-
When prompted, enter a unique number to create a new region.
Creating a new region destroys any existing data on the chosen database. -
Create and confirm a password for the database.
ManageIQ then configures the internal database. This takes a few minutes. After the database is created and initialized, you can log in to ManageIQ.
Configuring an External Database
Based on your setup, you need to configure the appliance to use an external PostgreSQL database. For example, you 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 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. It is recommended that external 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 that are expected to connect to the PostgreSQL instance, it might be
necessary to alter the max_connections
setting.
Note:
- ManageIQ requires PostgreSQL version 13.
- `postgresql.conf` controls the operation of all databases managed by the PostgreSQL instance, therefore it is not recommended to run other databases on this PostgreSQL instance.
Use the following steps to configure an external PostgreSQL database:
-
Start the appliance and open a terminal console.
-
Enter the
appliance_console
command. The appliance console summary screen is displayed. -
Press Enter to manually configure settings.
-
Select Configure Application from the menu.
-
Choose Create Region in External Database for the database location.
-
Enter the database hostname or IP address when prompted.
-
Enter the database name or leave blank for the default (
vmdb_production
). -
Enter the database username or leave blank for the default (
root
). -
Enter the chosen database user’s password.
-
Confirm the configuration if prompted.
ManageIQ configures an external database.
Configure Messaging
Configuring messaging is required for the appliance setup. It is recommended to configure the broker on the same appliance where your database is configured
Note: You can only have one Kafka broker per region.
-
You can either configure the current appliance as a Kafka broker, or point the appliance to an existing external Kafka broker.
Select the appropriate option either Configure this appliance as a messaging server or Connect to an external messaging system to connect to an external Kafka broker. Fill in the required Message Client Parameters, such as IP address, username and password.
-
Select Proceed.
appliance_console
applies the configuration that you requested. -
Restart
evmserverd
to pick up the changes.
Note: Use your Fully Qualified Domain Name (FQDN) as the messaging hostname rather than localhost
, ensure that a resolvable and reachable non-localhost name entry is present in /etc/hosts
.
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 and messaging.
-
Start the appliance and open a terminal console.
-
Enter the
appliance_console
command. The ManageIQ appliance summary screen displays. -
Press Enter to manually configure settings.
-
Select Configure Application from the menu.
-
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.
Note: All ManageIQ appliances in a multi-region deployment must use the same key.
-
Choose Join Region in External Database for the database location.
-
Enter the database hostname or IP address when prompted.
-
Enter the port number or leave blank for the default (
5432
). -
Enter the database name or leave blank for the default (
vmdb_production
). -
Enter the database username or leave blank for the default (
root
). -
Enter the chosen database user’s password.
-
Confirm the configuration if prompted.
-
Choose Connect to an external messaging system to connect to the external kafka broker located on the appliance with the external database
Note: You can only have one kafka broker per region
-
Enter the necessary Message Client Parameters such as the hostname/IP and username/password
-
Confirm the configuration if prompted.
Logging In After Installing ManageIQ
Once ManageIQ is installed, you can log in and perform administration tasks.
-
Browse to the URL for the login screen. For example, URL should be
https://xx.xx.xx.xx
- Enter the default credentials as listed for the initial login.
- Username: admin
- Password: smartvm
- Click Login.
Changing the Default Login Password
Change your password to ensure more private and secure access to ManageIQ.
-

Appendix
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 by using the command-line interface (CLI).
-
After starting the ManageIQ appliance, log in with a user name of
root
and the default password ofsmartvm
. This displays the Bash prompt for the root user. -
Enter the
appliance_console_cli
orappliance_console_cli --help
command to see a list of options available with the command, or simply enterappliance_console_cli --option <argument>
directly to use a specific option.
