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.

Accessing the Appliance Console

1. Start the appliance and open a terminal console.

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

3. Press Enter to manually configure settings.

4. Press the number for the item you want to change, and press Enter. The options for your selection are displayed.

5. Follow the prompts to make the changes.

6. 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:

• Install an internal PostgreSQL database to the appliance

• Configure the appliance to use an external PostgreSQL database

Configuring an Internal Database

1. Start the appliance and open a terminal console.

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

3. Press Enter to manually configure settings.

4. Select Configure Database from the menu.

5. 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.

6. Choose Create Internal Database for the database location.

7. 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).

8. 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.

9. When prompted, enter a unique number to create a new region.

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

10. 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 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 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.

Note:

• ManageIQ 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 ManageIQ databases with other types of databases in a single PostgreSQL instance.

1. Start the appliance and open a terminal console.

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

3. Press Enter to manually configure settings.

4. Select Configure Database from the menu.

5. You are prompted to create or fetch a security 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.

     Note:

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

6. Choose Create Region in External Database for the database location.

7. Enter the database hostname or IP address when prompted.

8. Enter the database name or leave blank for the default (vmdb_production).

9. Enter the database username or leave blank for the default (root).

10. Enter the chosen database user’s password.

11. Confirm the configuration if prompted.

ManageIQ will then configure the external database.

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

3. Press Enter to manually configure settings.

4. Select Configure Database from the menu.

5. 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.

6. Choose Join Region in External Database for the database location.

7. Enter the database hostname or IP address when prompted.

8. Enter the port number or leave blank for the default (5432).

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.

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.

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

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).

1. After starting the ManageIQ 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.

Database Configuration Options

v2_key Options

IPA Server Options

Note:

• In order to configure authentication through an IPA server, in addition to using Configure External Authentication (httpd) in the appliance_console, external authentication can be optionally configured via the appliance_console_cli (command-line interface).

• Specifying –host will update the hostname of the appliance. If this step was already performed via the appliance_console and the necessary updates that are made to /etc/hosts if DNS is not properly configured, the –host option can be omitted.

Certificate Options

Note: The certificate options augment the functionality of the certmonger tool and enable creating a certificate signing request (CSR), and specifying certmonger the directories to store the keys.

Other Options

Example Usage.

$ ssh root@appliance.test.company.com

To create a new database locally on the server by using /dev/sdb:

# appliance_console_cli --internal --dbdisk /dev/sdb --region 0 --password smartvm

To copy the v2_key from a host some.example.com to local machine:

# appliance_console_cli --fetch-key some.example.com --sshlogin root --sshpassword smartvm

You could combine the two to join a region where db.example.com is the appliance hosting the database:

# appliance_console_cli --fetch-key db.example.com --sshlogin root --sshpassword smartvm --hostname db.example.com --password mydatabasepassword

To configure external authentication:

# appliance_console_cli --host appliance.test.company.com
                        --ipaserver ipaserver.test.company.com
                        --ipadomain test.company.com
                        --iparealm TEST.COMPANY.COM
                        --ipaprincipal admin
                        --ipapassword smartvm1

To uninstall external authentication:

# appliance_console_cli  --uninstall-ipa
