Red Hat

Hi All,

I want to upgrade a VM server from RHEL5.4 to RHEL5.5.
My server is inside my office intranet and the yum.conf contents look like this:

Code:

[main]
cachedir=/var/cache/yum
keepcache=0
debuglevel=2
logfile=/var/log/yum.log
pkgpolicy=newest
distroverpkg=redhat-release
tolerant=1
exactarch=1
obsoletes=1
# Don't check keys for localinstall
gpgcheck=0
plugins=1
metadata_expire=1800
# Changed this because some mirrors go down and then
# re-trying takes forever.
timeout=7

The yum.repos.d has rhel-debuginfo.repo file which shows the follwoing.

Code:

[root@mysql-slave yum.repos.d]# cat rhel-debuginfo.repo
[rhel-debuginfo]
name=Red Hat Enterprise Linux $releasever - $basearch - Debug
baseurl=ftp://ftp.redhat.com/pub/redhat/linux/enterprise/$releasever/en/os/$basearch/Debuginfo/
enabled=0
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release

The system is not registered with RHN.
How do i upgrade this system? Please note that i don't have physical access to system. Hence CD/DVD option is ruled out.

Thanks

If you don't have a RHN subscription then essentially you cannot upgrade your system over the network (at least not with the official RHEL packages) unless you have your own RPM repository.

Not quite. Most recent LOMs and hypervisors provide some sort of "media virtualization" that allows you to mout a remote CD-ROM as if you were physically in front of the server.

Having that in mind, there are several options to perform and upgrade. Downloading the DVD media is actually free if you have a RHN account (with or without a RHEL entitlement); Then you can use this media as your RPM repo and upgrade all your packages or use the "Upgrade" option after booting from the DVD.

Similar to the above method you can download the DVD in your own computer, transfer the packages over the network to the server in question and then install/upgrade all the packages. The only "drawback" of this method is that the system *may* still show as RHEL 5.4 system after the upgrade, even if all the 5.4 packages are already installed (although you might be able to trick some apps by just modifying /etc/redhat-release).

Thank you very much sir.
Let me try mounting the CD/DVD remotely.Will post incase of any queries.

Thanks
