[Spacewalk-list] Updating Spacewalk Server from RHEL5 to RHEL6

[Boyd, Robert]

Ilya and Jens,

I suppose my language wasn't clear in my request.   I'm not upgrading from 1.6 to 1.7.   I already installed 1.7 on RHEL5.   I'm wanting to find out what the process would be to upgrade the server from RHEL5 to RHEL6.   So I think I can take out the items related to upgrading from 1.6 to 1.7 here.

Is that a fair statement?

Robert

Robert,

Here is what I would do - It may seem like a lot, but you will have a lot of flexibility with nothing but time and a bit of resource to use.

We are heavy vmware shop, but the same can be done in KVM/Xen or other virtualization platforms.

This is how I hand all major upgrades - that no one knows how it turns out.



1)      Create a virtual machine with proper parameters, and replicate your current RHEL5 with SPWLK 1.6 to test VM.


2)      Upgrade your spacewalk 1.6 to 1.7 on test VM that still runs RHEL5.


3)      Stand up another VM with RHEL6 and install vanilla  spacewalk 1.7, install mrepo and rsync mrepo configs and repositories, if its postgres or oracle, replicate the cofigs - using the same settings as you had in previous prod setup.



4)      Run export and import of DB, be it oracle or postgres from virtual RHEL5 (spacewalk 1.7) to virtual RHEL6 (spacewalk 1.7).



5)      Rsync the content of /var/satellite/redhat/* to virtual RHEL6 with spacewalk 1.7



*         You may need to match the hostnames or run hostname changer script.

*         There may be additional house cleaning, but in theory this should work.

Once you have the process squared away, you can do the same thing on your prod system, or promote your virtual instance to prod, if you run it virtually.

Good luck

I'm in the early stages of setting up Spacewalk on a RHEL5 server.  The installation was started by someone else before 1.7 came out so they decided to hold of on RHEL6.   Most of the environment here is running RHEL5 and we only have 1 or 2 test servers running RHEL6.   I'm wondering how complicated it's likely to be to upgrade the server to RHEL6.   I just found out this morning that RHEL6.3 was released recently, so I'm thinking I might be better off to bite the bullet before I get a bunch of servers registered into the system.   Have you gone through an OS upgrade on your server?  What are the essential steps?   I have mrepo and Spacewalk running on the same server currently.   What would I need to do to make the upgrade as smooth as possible without completely re-inventing the server from scratch?   I know it's possible to do a database backup and restore it after upgrading.  I looked at the wiki page for doing a spacewalk 1.6->1.7 upgrade.   It looks like some of the pieces might be pulled from that procedure.    Is there a Red Hat guide for upgrading the server hosting Satellite Server?   That would presumably be pretty similar to what I'd need to do.

Thanks for any thoughts you're willing to share about this.   If there's already a guide written for this great!  If not, maybe now is the time to add one to the wiki?  And I'd be willing to help write and verify it.

Thanks,
Robert
