Instalación de Red Hat Enterprise Virtualization Manager

Artículos relacionados

Vamos a instalar Red Hat Enterprise Virtualization Manager que es la herramienta de gestión centralizada en una infraestructura de virtualización de Red Hat. Este servicio permite al administrador gestionar la infraestructura a través de un interfaz web, configurar los host, añadir almacenamiento, definir redes, crear máquinas virtuales…

También permite el acceso de los usuarios a sus máquinas virtuales.

Instalación del sistema

Instalamos un servidor con Red Hat Enterprise Linux 6.5 seleccionando la opción de Servidor básico.
Asignamos un nombre y una dirección IP fija. En mi caso los datos son:
- Nombre: REDHAT01.negu.local
- IP: 10.0.6.1/16

Configuración de canales y repositorios

Uno de los primeros pasos es registrar el sistema en Red hat Network y asignar los canales y repositorios que nos permitirán tener acceso a los paquetes necesarios para realizar la instalación.

Registramos el sistema en RedHat con el siguiente comando

subscription-manager register

1	subscription-manager register

Asignamos los dos canales
- Red Hat Enterprise Virtualization for Servers
- Red Hat Enterprise Linux OpenStack Platform Preview
Ejecutamos el siguiente comando para obtener los identificados de los dos canales

subscription-manager list --available

1	subscription-manager list --available

Añadimos cada canal indicando el ID

subscription-manager attach --pool=<em><code>POOLID</code></em>

1	subscription-manager attach --pool=<em><code>POOLID</code></em>

Añadimos los repositorios

rhel-6-server-rhev-rpms
rhel-6-server-rhevm-3.3-rpms
jb-eap-6-for-rhel-6-server-rpms
rhel-x86_64 -server-supplementary-6

<strong><code>yum-config-manager --enable </code></strong><em><code>REPO_NAME</code></em>

1	<strong><code>yum-config-manager --enable </code></strong><em><code>REPO_NAME</code></em>

Actualizamos el sistema

yum -y update

1	yum -y update

Instalación de Red Hat Enterprise Virtualization Manager

Utilizamos yum para instalar todos los paquetes necesarios, con el siguiente comando

yum -y install rhevm

1	yum -y install rhevm

Cuando termina la instalación ejecutamos el siguiente comando para configurar los servicios.

engine-setup
