Setting_Up_the_OS_Repository_on_the_Mgmt_Node

Get the Requisite Packages From the Distro

xCAT depends on several packages that come from the Linux distro. Follow this section to create the repository of the OS on the Management Node.

[RHEL] Setup repository

To make the necessary RHEL RPM prereqs available to the xCAT install process, mount the RHEL CD/DVD or ISO and then create a repo file in /etc/yum.repos.d that points to it.

If you have the RHEL iso files:

If the RHEL distro only has one iso file:

Copy the iso file to any directory, such as /iso

mkdir /iso
cp RHEL5.2-Server-20080430.0-ppc-DVD.iso /iso/

Mount the iso file to a directory such as /iso/rhels5.2

cd /iso
mkdir /iso/rhels5.2
mount -o loop RHEL5.2-Server-20080430.0-ppc-DVD.iso /iso/rhels5.2

Create a YUM repository file, for example, rhel-dvd.repo, under directory /etc/yum.repos.d. The YUM repository contents should look like:

[rhe-5-server]
name=RHEL 5 SERVER packages
baseurl=file:///iso/rhels5.2/Server
enabled=1
gpgcheck=1

Note: To make the YUM repository work persistently after management node reboot, the iso mount needs to be added into the /etc/fstab, or add the mount command into Linux startup scripts.

If the RHEL distro has more than one iso files

For each iso file:

• Loopback mount the iso file
• For the 1st iso file only, cd to the mounted directory and run: rpm --import RPM-GPG-KEY-redhat-release
• Copy the RPMs from the Server subdirectory of the mounted directory to a directory on your hard disk (for example /rhels5.3). You can put the RPMs from all of the iso files into the same directory.
• cd into the newly created RPM directory, install the createrepo RPM, and run: createrepo .

• Create a YUM repository file, for example, rhel-cd.repo, in directory /etc/yum.repos.d. The YUM repository contents should look like:

  [rhel-5.3]
  name=RHEL 5.3 from directory
  baseurl=file:///rhels5.3
  enabled=1
  gpgcheck=1

For either case above:

change directory to where the RHEL CD image is and run

cd /iso/rhels5.2
rpm --import RPM-GPG-KEY-redhat-release

Check that the repo is set up correctly by looking for one rpm:

yum list screen

Note: For RHEL 6.1 and RHEL 6.2 on x86_64 platform, the package perl-Net-Telnet, which is required by xCAT, but is not included in the repository <os_name>/Server, you need to add the perl-Net-Telnet into the yum repository through whatever method, a simple way is to add a new yum repository that points to the <os_name>/HighAvailability:

 [root@xcatmn ~]# cat /etc/yum.repos.d/rhels6.1.ha.repo 
 [rhe-6.1-server-ha]
 name=RHEL 6.1 HA packages
 baseurl=file:///iso/rhels6.1/x86_64/HighAvailability
 enabled=1
 gpgcheck=1
 [root@xcatmn ~]#

[SLES] Setup repository

If you have a SLES ISO:

mkdir /iso
copy SLES11-DVD-ppc-GM-DVD1.iso to /iso/
mkdir /iso/1
cd /iso
mount -o loop SLES11-DVD-ppc64-GM-DVD1.iso 1
zypper ar [../../../iso/1 file:///iso/1] sles11
or
zypper ar file:///iso/1  sles11

Check that the repo is set up correctly by looking for one rpm:

zypper search --match-exact -s screen

[FEDORA] Setup the repository

If your management node has access to the internet, you can simply create a file called /etc/yum.repos.d/fedora-internet.repo that contains:

[fedora-everything]
name=Fedora $releasever - $basearch
failovermethod=priority
#baseurl=http://download.fedora.redhat.com/pub/fedora/linux/releases/$releasever/Everything
/$basearch/os/
mirrorlist=http://mirrors.fedoraproject.org/mirrorlist?repo=fedora-$releasever&arch=$basearch
enabled=1
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-fedora [../../../etc/pki/rpm-gpg/RPM-GPG-KEY
file:///etc/pki/rpm-gpg/RPM-GPG-KEY]

Check that the repo is set up correctly by looking for one rpm:

yum list screen

If your management node does not have internet access, then download the iso of Fedora OS and setup the repository like [RHEL] Setup repository part.
