Create a Yum repository on Exalogic 2.0.6.2.x

This document describes how to create a yum repository on ZFS Storage inside an Exalogic machine.

Prepare your environment

Create a zfs share

Connect to one of the storage server to create a share.

This share hosts the Exalogic yum repository.

• Connect to storage server

Add Share to project

• Create a share named ‘yum-repo’ on common project

Add permissions on share

• Add Nfs Exception to access the share from IPoIB-vserver-shared-storage network.
• Add read/Write and root access.

Prepare repository

Mount ‘yum-repo’ share on a vServer

- Edit /etc/fstab and add a entry :

172.17.0.5:/export/common/yum-repo /export/common/yum-repo nfsv4 rw,bg,hard,nointr,rsize=131072,wsize=131072 0 0

With 172.17.0.5 is the IPoIB address of the storage server on IPoIB-vserver-shared-storage

• Create directory /export/common/yum-repo

# mkdir –p /export/common/yum-repo

• Mount directory on vServer :

# mount /export/common/yum-repo

Prepare files

• Download Oracle enterprise Linux iso file on https://edelivery.oracle.com

• upload Oracle Enterprise Linux iso file in the share :

With your favorite scp client, copy Oracle Enterprise Linux iso file to /export/common/yum-repo.

• Create temporary directory and repository version directory :

# mkdir –p /export/common/yum-repo/tmp /export/common/yum-repo/OEL_6.5

• mount iso file on the temporary directory :

# mount -o loop /export/common/yum-repo/OEL_6.5.iso /export/common/yum-repo/tmp

• Copy iso content in repository directory :

# cp -r /export/common/yum-repo/tmp/* /export/common/yum-repo/OEL_6.5

Create your repository

• To create repository, you must install createrepo package.

This package can be found on temporary directory previously created

Control if already installed :

# rpm –qa |grep createrepo
createrepo-0.4.11-3.el5

• Install package :

# rpm –Uvh /export/common/yum-repo/tmp/createrepo-0.4.11-3.el5.x86_64.rpm /export/common/yum-repo/tmp/deltarpm-* /export/common/yum-repo/tmp/python-deltarpm-*

• At this step, remove any link to Packages directory in subdirectories to avoid loop in repository :

# find . -name Packages -type l -exec rm -f {} \;

• Create repository :

# cd /export/common/yum-repo/OEL_6.5/
# createrepo .
3380/3380 - Cluster/ipvsadm-1.24-13.el5.x86_64.rpm pmpmx86_64.rpm

Saving other metadata

Cleanup environment

• Unmount iso file :

# cd /export/common/yum-repo/
# umount –f /export/common/yum-repo/tmp/

• Delete iso file :

# rm -f /export/common/yum-repo/OEL_5.8.iso

Configure yum client

Update configuration files

• Update /etc/yum.conf file :

Add exclusion to Exalogic specific package which cannot be updated:

exclude=kernel* compat-dapl* dapl* ib-bonding* ibacm* ibutils* ibsim* infiniband-diags* kmod-ovmapi-uek* libibcm* libibmad* libibumad* libibverbs* libmlx4* libovmapi* librdmacm* libsdp* mpi-selector* mpitests_openmpi_gcc* mstflint* ofed* openmpi_gcc* opensm* ovm-template-config* ovmd* perftest* qperf* rds-tools* sdpnetstat* srptools* xenstoreprovider* initscripts* nfs-utils*

• Create /etc/yum.repos.d/local_yum.repo file with the following content:

[local_yum]
name=Exalogic Yum Rack
baseurl=http://172.17.0.5/shares/export/common/yum-repo/OEL_6.5.iso
gpgcheck=0
enabled=1

Refresh yum database

Refresh yum client on each machine now configured with the local repository.

• First, clean yum cache :

# yum clean all
Loaded plugins: rhnplugin, security
Cleaning up Everything

• Recreate yum cache and headers :

# yum repolist
Loaded plugins: rhnplugin, security
