3.3. Configuring the Red Hat Enterprise Virtualization Manager
After you have installed the rhevm package and dependencies, you must configure the Red Hat Enterprise Virtualization Manager using the
engine-setupcommand. This command asks you a series of questions and, after you provide the required values for all questions, applies that configuration and starts the
engine-setupcreates and configures the Manager database locally on the Manager machine. Alternatively, you can configure the Manager to use a remote database or a manually-configured local database; however, you must set up that database before running
engine-setup. To set up a remote database see Appendix D, Preparing a Remote PostgreSQL Database for Use with the Red Hat Enterprise Virtualization Manager. To set up a manually-configured local database, see Appendix E, Preparing a Local Manually-Configured PostgreSQL Database for Use with the Red Hat Enterprise Virtualization Manager.
engine-setupwill configure a websocket proxy on the Manager. However, for security and performance reasons, the user can choose to configure it on a separate host. See Appendix F, Installing a Websocket Proxy on a Separate Machine for instructions.
engine-setupcommand guides you through several distinct configuration stages, each comprising several steps that require user input. Suggested configuration defaults are provided in square brackets; if the suggested value is acceptable for a given step, press Enter to accept that value.
Procedure 3.2. Configuring the Red Hat Enterprise Virtualization Manager
- Run the
engine-setupcommand to begin configuration of the Red Hat Enterprise Virtualization Manager:
- Press Enter to configure the Manager:
Configure Engine on this host (Yes, No) [Yes]:
- Optionally allow access to a virtual machines's serial console from the command line.
Configure VM Console Proxy on this host (Yes, No) [Yes]:Additional configuration is required on the client machine to use this feature. See Opening a Serial Console to a Virtual Machine in the Virtual Machine Management Guide.
- Optionally allow
engine-setupto configure a websocket proxy server for allowing users to connect to virtual machines via the noVNC or HTML 5 consoles:
Configure WebSocket Proxy on this machine? (Yes, No) [Yes]:To configure the websocket proxy on a separate machine, select
Noand refer to Appendix F, Installing a Websocket Proxy on a Separate Machine for configuration instructions.
- Press Enter to accept the automatically detected hostname, or enter an alternative hostname and press Enter. Note that the automatically detected hostname may be incorrect if you are using virtual hosts:
Host fully qualified DNS name of this server [autodetected host name]:
engine-setupcommand checks your firewall configuration and offers to modify that configuration to open the ports used by the Manager for external communication such as TCP ports 80 and 443. If you do not allow
engine-setupto modify your firewall configuration, then you must manually open the ports used by the Manager.
Setup can automatically configure the firewall on this system. Note: automatic configuration of the firewall may overwrite current settings. Do you want Setup to configure the firewall? (Yes, No) [Yes]:If you choose to automatically configure the firewall, and no firewall managers are active, you are prompted to select your chosen firewall manager from a list of supported options. Type the name of the firewall manager and press Enter. This applies even in cases where only one option is listed.
- Choose to use either a local or remote PostgreSQL database as the Manager database:
Where is the Engine database located? (Local, Remote) [Local]:
- If you select
engine-setupcommand can configure your database automatically (including adding a user and a database), or it can connect to a preconfigured local database:
Setup can configure the local postgresql server automatically for the engine to run. This may conflict with existing applications. Would you like Setup to automatically configure postgresql and create Engine database, or prefer to perform that manually? (Automatic, Manual) [Automatic]:
- If you select
Automaticby pressing Enter, no further action is required here.
- If you select
Manual, input the following values for the manually-configured local database:
Engine database secured connection (Yes, No) [No]: Engine database name [engine]: Engine database user [engine]: Engine database password:
- If you select
Remote, input the following values for the preconfigured remote database host:
Engine database host [localhost]: Engine database port : Engine database secured connection (Yes, No) [No]: Engine database name [engine]: Engine database user [engine]: Engine database password:
- Select Gluster, Virt, or Both:
Application mode (Both, Virt, Gluster) [Both]:Both offers the greatest flexibility. In most cases, select
Both. Virt application mode allows you to run virtual machines in the environment; Gluster application mode only allows you to manage GlusterFS from the Administration Portal.
- Set a password for the automatically created administrative user of the Red Hat Enterprise Virtualization Manager:
Engine admin password: Confirm engine admin password:
- Set the default value for the
wipe_after_deleteflag, which wipes the blocks of a virtual disk when the disk is deleted.
Default SAN wipe after delete (Yes, No) [No]:
- The Manager uses certificates to communicate securely with its hosts. This certificate can also optionally be used to secure HTTPS communications with the Manager. Provide the organization name for the certificate:
Organization name for certificate [autodetected domain-based name]:
- By default, external SSL (HTTPS) communication with the Manager is secured with the self-signed certificate created earlier in the configuration to securely communicate with hosts. Alternatively, choose another certificate for external HTTPS connections; this does not affect how the Manager communicates with hosts:
Setup can configure apache to use SSL using a certificate issued from the internal CA. Do you wish Setup to configure that, or prefer to perform that manually? (Automatic, Manual) [Automatic]:
- Optionally allow
engine-setupto make the landing page of the Manager the default page presented by the Apache web server:
Setup can configure the default page of the web server to present the application home page. This may conflict with existing applications. Do you wish to set the application as the default web page of the server? (Yes, No) [Yes]:
- Optionally create an NFS share on the Manager to use as an ISO storage domain. The local ISO domain provides a selection of images that can be used in the initial setup of virtual machines:
Configure an NFS share on this server to be used as an ISO Domain? (Yes, No) [Yes]:
- Specify the path for the ISO domain:
Local ISO domain path [/var/lib/exports/iso]:
- Specify the networks or hosts that require access to the ISO domain:
Local ISO domain ACL: 10.1.2.0/255.255.255.0(rw) host01.example.com(rw) host02.example.com(rw)The example above allows access to a single /24 network and two specific hosts. See the
exports(5)man page for further formatting options.
- Specify a display name for the ISO domain:
Local ISO domain name [ISO_DOMAIN]:
- Optionally, use the
engine-setupcommand to allow a proxy server to broker transactions from the Red Hat Access plug-in:
Would you like transactions from the Red Hat Access Plugin sent from the RHEV Manager to be brokered through a proxy server? (Yes, No) [No]:
- Review the installation settings, and press Enter to accept the values and proceed with the installation:
Please confirm installation settings (OK, Cancel) [OK]:
- If you intend to link your Red Hat Enterprise Virtualization environment with a directory server, configure the date and time to synchronize with the system clock used by the directory server to avoid unexpected account expiry issues. See Network Time Protocol Setup in the Red Hat Enterprise Linux Deployment Guide for more information.
When your environment has been configured, the
engine-setupcommand displays details about how to access your environment. If you chose to manually configure the firewall,
engine-setupprovides a custom list of ports that need to be opened, based on the options selected during setup. The
engine-setupcommand also saves your answers to a file that can be used to reconfigure the Manager using the same values, and outputs the location of the log file for the Red Hat Enterprise Virtualization Manager configuration process.
Proceed to the next section to see how to connect to the Administration Portal as the
admin@internaluser. Then, proceed with setting up hypervisor hosts, and attaching storage.
