I am about to upgrade a RHE 4 Dell 2850 server to Centos 5. The RHE 4 was/is running Virtualmin.
The RHE 4 system was recently corrupted by a "helpful" engineer who managed to recurse permissions/owner settings from the domain all the way up to root.
A company I use ("For Linux") here in the UK sorted out the worst of it so I have some website functionality and email, but a few things like php forms do not send emails through postfix now and similar quirks.
So a complete reinstall has been decided upon after what can only be described as the week from hell :-) (don't those weeks just seem to occur all to frequently in IT though...:-)? ) Just to clarify too the "helpful" engineer was not from the company For Linux who are always great, this guy was doing some voluntary work on a charity domain I host.
I have all the virtualmin domains / websites backed up to external usb drive using the virtualmin utility.
My question is this... Can I install Centos 05 to the Dell 2850 preserving the (Raid 1 hardware) partitions I created whilst running under RHE4. My hope / anticipation is that this will enable me to set the default permissions back to the OS and then reinstall Virtualmin.
If I completely reformat and remove the partitions is that likely to cause any restore problems when restoring the virtualmin domains that were backed up if the partitiion structure is different?
OR and preferably.... Once I have the physical server sorted out and running can I install Centos 05 onto a virtual machine (using vmware server) and use that as the main webserver, install virtualmin onto that and restore the domains to the virtual server which will of course give some resiliance to the whole setup in the future in the event of hardware failure or similar OS corruption.
Still claiming to be a Linux Newbieish I'm afraid after three years as Webmin and Virtualmin have made it so easy to manage the server that when I get real problems I am still stuck! So any replies might well need a kind of step by step if any commands need running!
Any help tips info etc would be most appreciated as I would like to try an get the job done this weekend if possible.
