Suggestions on CentOS5 installation on new machine from old Fedora4

Ericxx · 02-19-2010, 09:41 PM

Hello,

I am trying to port the current Fedora4 system to the CentOS5 on a new harddisk. Actually, the Fedora4 system is constantly being hacked due to my lazy update. So i prefer a fresh install of CentOS5. I am not clear what files need copy and what does not need for ease and for avoiding possible backdoors. Kinda a big problem, but a couple of points from you are highly appreciated.

Regards,
Eric

do a 100% clean install after reformatting the server.

To expand: backup any user defined data and any cfg files.
Do a clean install of Centos; restore the user data back to the equiv areas.
For MySQL that'd be a mysqldump to export/backup.
Note that not all your cfgs will be the same on Centos, so you'll have to read through and amend manually.

Thank you, John and Chris.
To Chris, so i just copied the user data under /home to the new /home and modify some config files if necessary. Is it ok that I mount the old harddisk and copy directly onto the new machine after the clean install?

Thanks,
Eric

Given the differences between Fedora 4 and Centos 5, TBH I wouldn't rely on personal settings type files to be the same. You'll have to eyeball them I'm afraid.
I really meant any data files like DBs, general text files, docs etc.
Toolsets have changed, so it's tricky to give exact advice unless I'd done the same.
