I am currently wanting to set up new clusters.
Each cluster is defined by its software installed, software settings, and its home folder files.
I want only the above to be cloned and not things like:
/etc/network/interfaces/etc/ssh/sshd_config/etc/hostname
And please help with other things that need to be unique so that not to cause the system to malfunction? For example when reading this article on tar backups, I noticed that they said not to include
"/proc, /sys, /mnt, /media, /run and /dev directories in root"
So what I am wanting to be able to do is, create a new ubuntu 14.04 LTS server from scaleway.com and send a .tar across with all the system files needed above. After that I will be expected to customise the /etc/network/interfaces, /etc/ssh/sshd_config, /etc/hostname and whatever else you think I need to(?) And then I would like to use sshfs to keep all the important system files (as mentioned above) between the clusters in sync that I may want to edit in the future.
I tried backing up the main cluster like this:
sudo tar -cvpzf /fullBackup.tar.gz --one-file-system --exclude=/proc exclude=/tmp --exclude=/mnt --exclude=/dev --exclude=/sys /
and then running this on the new scaleway.com cluster after moving fullBackup.tar.gz:
sudo tar -xvpzf /fullBackup.tar.gz -C / --numeric-owner
but I just start recieving lots of Exec format errors? (I think it may have something to do with the ARM architecture from a PI to a scaleway.com server [an issue that I want to irradicate]) This is an example of backing up wayyy to much.
