Update de servidor Spacewalk

Este manual describe la actualización de la versión 1.5 a 1.7 de Spacewalk sobre la distribución CentOS. Será aplicable a futuras versiones de software, salvo que cambien las exigencias.

Requisitos

  • Spacewalk corriendo sobre CentOS, con los repositorios Base y Epel configurados.
  • Tener habilitado en yum el acceso a la versión más reciente.
  • Usuario root.

PASOS PREVIOS

  • Comprobamos el estado del servidor:

# /usr/sbin/spacewalk-service status

  • Paramos los servicios del servidor:

# /usr/sbin/spacewalk-service stop

  • Paramos oracle-xe:

# /etc/init.d/oracle-xe stop

  • Comprobamos que tenemos en el servidor los repositorios spacewalk.repo, spacewalk-client.repo, spacewalk-client-tools.repo y spacewalk-source.repo configurados :

[root@serverspacewalk ~]# ls /etc/yum.repos.d/

CentOS-Base.repo CentOS-Vault.repo spacewalk-client.repo

CentOS-Debuginfo.repo epel.repo spacewalk-client-tools.repo

CentOS-GN-x64.repo.old epel-testing.repo spacewalk.repo

CentOS-Media.repo GPL spacewalk-source.repo

  • Revisamos la versión de repo:
[root@serverspacewalk ~]# yum list spacewalk-repo

Loaded plugins: fastestmirror

Installed Packages

spacewalk-repo.noarch 1.5-1.el5 installed

  • Aprovechando la parada, realizaremos un update de paquetes del servidor

# yum clean all

# yum –y update –exclude=cobbler

# reboot

Update software

  • Actualizamos el esquema de Spacewalk:

# /usr/bin/spacewalk-schema-upgrade

[root@serverspacewalk ~]# /usr/bin/spacewalk-schema-upgrade
