Configuracion de subscription-manager

[email protected]:~$ subscription-manager register --username <username> --password <password>
  • Posiblemente aqui pedira aceptar terminos y condiciones de la pagina de redhat, en dado caso entrar y aceptar los terminos y condiciones para continuar.
[email protected]:~$ subscription-manager list --available --all
[email protected]:~$ subscription-manager attach --pool=<POOL_ID>
[email protected]:~$ subscription-manager register
[email protected]:~$ subscription-manager refresh

Configuración de Bastión (repositorio)

[email protected]:~$ subscription-manager repos \
        --enable="rhel-7-server-rpms" \
        --enable="rhel-7-server-extras-rpms" \
        --enable="rhel-7-server-ose-3.11-rpms" \
        --enable="rhel-7-server-ansible-2.6-rpms"

Instalar paquetes necesarios RHEL

[email protected]:~$ yum -y install yum-utils createrepo docker git

Instalar paquetes necesarios Fedora

[email protected]:~$ dnf -y install yum-utils createrepo docker git

Montar disco adicional sin formato (Crearlo en herrmaienta del hypervisor)

Crear el directorio donde se almacenarán los repositorios

[email protected]:~$ mkdir -p /opt/repos

[email protected]:~$ cd /opt/repos

Sincronizar los paquetes y crear los repositorios locales

[email protected]:~$ for repo in \
rhel-7-server-rpms \

  createrepo -v /opt/repos/${repo} -o /opt/repos/${repo}
done

Instalar servicio httpd

[email protected]:~$ yum install httpd

Editar archivo de configuración de httpd '(/etc/httpd/conf/httpd.conf)' con el siguiente contenido:

Note that from this point forward you must specifically allow
# particular features to be enabled - so if something's not working as
# you might expect, make sure that you have specifically enabled it
# below.
#

#
# DocumentRoot: The directory out of which you will serve your
# documents. By default, all requests are taken from this directory, but
# symbolic links and aliases may be used to point to other locations.
#
DocumentRoot "/opt/repos"

#
# Relax access to content within /var/www.
#
<Directory "/opt/repos">
   AllowOverride None
   # Allow open access:
   Require all granted
</Directory>

# Further relax access to the default document root:
<Directory "/opt/repos">
   #
   # Possible values for the Options directive are "None", "All",
   # or any combination of:
   #   Indexes Includes FollowSymLinks SymLinksifOwnerMatch ExecCGI MultiViews
   #
   # Note that "MultiViews" must be named *explicitly* --- "Options All"
   # doesn't give it to you.
   #
   # The Options directive is both complicated and important.  Please see
   # http://httpd.apache.org/docs/2.4/mod/core.html#options
   # for more information.
   #
   Options Indexes FollowSymLinks

   #
   # AllowOverride controls what directives may be placed in .htaccess files.
   # It can be "All", "None", or any combination of the keywords:
   #   Options FileInfo AuthConfig Limit
   #
   AllowOverride None

   #
   # Controls who can get stuff from this server.
   #
   Require all granted
</Directory>

Agregar permisos al directorio y restablecer los contextos

[email protected]:~$ chmod -R +r /opt/repos
[email protected]:~$ restorecon -vR /opt/repos

Agregar reglas de firewall

[email protected]:~$ sudo firewall-cmd --permanent --add-service=http
[email protected]:~$ sudo firewall-cmd --reload

Habilitar e iniciar el servicio de httpd

[email protected]:~$ systemctl enable httpd
[email protected]:~$ systemctl start httpd

Clonar la Maquina Virtual y esa maquina sera el nodo de infraestructura adicional.

Editar el archivo /etc/yum.repos.d/ose.repo en todos los nodos de la infraestructura con el siguiente contenido:
