dtc_install_centos - bootstrap a CentOS install to use in a chroot or
dtc_install_centos <install root> <yum environment>
This shell script is part of the dtc-xen package, generally to be used
by the dtc panel to install a new a Xen VPS server. This script is
called by dtc_reinstall_os when the user chooses to install the CentOS
How it works: it generates a temporary yum configuration in the yum
environment directory, that directs yum to act inside the install root
instead of in the base system; then it kindly requests yum to install
the basesystem, centos-release and yum packages onto it. Yum then uses
the configuration to download the required (usually, security-updated)
packages and then perform the RPM installation process under the
It requires both RPM and yum. It does work under Debian (it was
developed in Ubuntu first). It should also work on RPM-based systems
without destroying the system-wide RPM and yum configurations.
Target directory where CentOS will be deployed. Must exist beforehand.
Directory where yum will store the repository manifests and
configuration. Will be automatically created. Cached RPMs and
manifests will be left, as usual, in a directory var/cache/yum inside
the install root.
dtc_install_centos /root/yum /xen/13
This will setup the operating system in /xen/13, with the CentOS
configuration folder in /root/yum.
It’s limited to CentOS 5 at the moment.
It must be run as root.
Under some circumstances, the installation process itself may kill
processes running on the host machine. The chroot yum does should be
sufficient to avoid this, but we haven’t been able, yet, to ascertain
why this fails sometimes.
