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:
Loaded plugins: fastestmirror
Loading mirror speeds from cached hostfile
* base: sunsite.rediris.es
* epel: ftp.cica.es
* extras: sunsite.rediris.es
* updates: sunsite.rediris.es
Installed Packages
spacewalk-repo.noarch 1.5-1.el5 installed
- Habrá que instalar (actualizar) el repo de la nueva versión:
# rpm -Uvh http://spacewalk.redhat.com/yum/1.7/RHEL/5/x86_64/spacewalk-repo-1.7-5.el5.noarch.rpm
# yum list spacewalk-repo
- 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-upgradeSchema upgrade: [spacewalk-schema-1.5.6-1.el5] -> [spacewalk-schema-1.7.55-1.el5 ]
