Server :: Clone Or Duplicate Installation To Other Machines?
Sep 20, 2010
I'm planing to get 4 dedicated, remote servers for my start up, the question I have is: how to do only one installation and then duplicate or clone this installation into all the other machines. I could install those 4 servers manually, but the problem is - we have a lot of things that our application needs, and later there will be more servers. So an automatic way to do that would be better. We are using Debian. Perhaps there's a way to create a "big package" that will contain all of the necessary software in it, then simply require from the hosting provider that all of our servers come with Debian installed, and then manually upload the "big package" and install it?

If I clone a debian linux from a server to a harddisk, can I simply plug this clone harddisk to another server and boot it up to use as the primary OS disk for this server, even though the 2 servers may not be the same configuration, same make and model?

I have a bunch of computers with the same configuration, so I would like to install Ubuntu only to one master computer and later on just copy the partition layout and the filesystem unto other computers. Previously I was able to simply copy the partition layout (via the sfdisk utility), the filesystem (a simple "cp -a") and install Grub (via script). Now I had to use the parted utility to partition the 2TB drive and Grub2 is the default boot loader.
My questions are now:
1. How do I copy the partition layout from /dev/sda (master) to /dev/sdb (clone)?
2. How do I batch install install Grub2 to the other disk (e.g. /dev/sdb) ?
In Grub 0.97 it used to be something like that:
Code:
# GRUB the disk
grub --no-floppy --batch <<EOF_GRUB
root ($GRUB,0)
setup ($GRUB)
quit
EOF_GRUB .....
In Grub 2 I tried with:
Code:
grub-install --force --root-directory=/mnt/sdb1/ /dev/sdb
Only to get this error: .....
The Grub2 syntax is way different compared to Grub0.97. Yes, I do could use the Grub2-suggested option but since the partition layouts on both partitions are equal, I see little point in setting the BIOS Boot Partition option, since the master computer works without it and I don't remember any error message during the install.

we are having new printers. At the moment we over 1000 machines on multiple sites but no print server they are manually added on the machine ( I know don't ask).
Anyway there is no way they would let use a windows server so the only option I have is to use linux however I little unsure if it is capable of doing the job I need it to do. Basically I want to add the printers on the linux server either using samba or ipp (I would assume samba would be best).
The reason i want to do this is when we have to do around the machines I just want to go around the machines and just the map the printer and it brings down the driver and config etc as we want them to duplex. The issue is I been trying to gain information on the internet and getting conflicting information apparently I can add the windows driver onto the server so when I map the printer it brings it down. However some guides state you still have through the whole process of adding the printer and then choosing the driver etc. Which kinda of makes it pointless to do the printer server since I would already have to do this anyway if we don't have one.
I just want to go be able to go around the machines and for example click star run and do something like \192.168.1.1printer01 and then it done kind of thing.

I wish to setup a network that works like windows but for with lunix of course!. It will need to be able to handle security/DNS/DHCP & Document store from one location. I've been doing some reading and have found that I think I need to be using one of the following:
LDAP
NIS
Kerberos
I have looked at a few Linux based OS's. I did notice that when you install fedora live desktop it gives you the option to connect to one of the above. So I am looking for a complete solution.
1. How to setup fedora to act as server for my needs (or other Linux build)
2. Add fedora/linux mint machines to server to use new security settings. (or other linux build)

My server is really slow. When I did a top -c or ps aux, below shows up. Shouldn't there be only one? Shall I kill all those processes and leave only one?

The place I work has a web/dns server on opensuse 10 up and running hosting a few websites (our company one & a few vhost ones). The box was set up before I got here. Now we are wanting to create a new 11.2 server that is basically a backup / clone of 1st server in case it goes down.

I'm new to fedora (still trying it out) but have many years of experience on other distributions -- mostly gentoo. Anyway, I'm wondering if someone can tell me what all is needed to clone a fedora install. I cloned the partitions, updated fstab with real device node entries (removed all the UUID stuff), and modified grub.conf with the same changes (as well as all the normal/misc changes needed in /etc for things like hostname, network, ethx naming, etc). However when I try to boot it complains that it cant find the old UUID.
I thought this might be specified in the initrd but I uncompressed it and couldn't find any reference to the uuid anywhere. Where does fedora keep this UUID information at? Right now I'm just trying to clone a mythdora box to another one but in the past I've configured a single gentoo install and cloned it on dozens of other computers.

I'm nearly at the end of creating a shell script that automates changing network settings by prompting the user for desired settings, then applying them.
In the course of my development, I created temporary copies of /etc/sysconfig/network-scripts/ifcfg-eth0 (/etc/sysconfig/network-scripts/ifcfg-eth0_tmp1, for example) so as to not alter the original file. Little did I know that on boot the system would attempt to load each of these kinds of files and associate it with an ethernet connection, in this case eth0.
So..... now there are multiple copies in the /etc/sysconfig/network-scripts diretory that essentially have the same settings. They are..
/etc/sysconfig/network-scripts/ifcfg-eth0
/etc/sysconfig/network-scripts/ifcfg-eth0_tmp1
/etc/sysconfig/network-scripts/ifcfg-eth0_tmp2
Now when the system boots, it attempts to load them all. The boot doesn't appear to complete, and I can't ping, login, or otherwise access the system through convention routes (putty, etc.).
The easy solution would be to delete the tmp files and reboot. Now, how do I do that without being able to log in to the server. It's a VM by the way, if that makes a difference.

I am currently running x86_64 F14. I am replacing the HDD(s) with one SSD and one HDD. What I want to do is a fresh install but pull all of the packages over from current install. I am planning on backing up /home and all of that so I can just rsync it. One of the issues though is that I currently use LVM. LVM does not support TRIM yet for the SSD. So I was just going to use ext4 and an extended partition for all of my filesystems. Can I just make a kickstart file that will have all of my current installed packages in it and pass that to the install? Seems like I remember that from my RHCE class. Sadly I don't use kickstart enough to remember.

My wife's laptop has XP on it, I installed Ubuntu using wubi apparently. I thought I had made a separate partition and made a true dual boot system but I guess I didn't. Is there a way to clone the wubi install to it's own partition and add the boot loader after or am I going to have to do a fresh install and set everything up again? I am surprised that she has taken to Ubuntu as well as she has, I thought she would hate it but she actually prefers it to windows now..

My HDD crashed (it wasn't completely disastrous, though). I was able to get my Ubuntu 10.10 partition of the disk with dd_rescue. I can see all of the data in the partition and everything. dd_rescue reported that there were no errors.Now, I have a fresh HDD, and I copied the image that I created with Gparted, and turned the boot flag on. I turn my system on, and all I get is a flashing cursor in the corner of the screen.I get the feeling that this would be easy for a seasoned user, but I'm not sure where to go. I originally got some information about cloning partitions here: [URL] But, it doesn't tell you how to reload the image after you make it.

I often run various computers from my Ubuntu 10.04 USB startup disk. Every now and then, people get interested and want a copy of their own. Since I have installed a few extras (VLC, codecs, flash etc) on the disk, not just the out of the box 10.04, I would like to create a clone of the USB startup disk, to give away. How can it be done?

I have a couple of beginner questions;I have checked out some source code in a directory, not inside the home directory, using: Code:git clone git://git.videolan.org/ffmpeg.git ffmpeg-gitI moved the folder around (was not originally in the right directory), and now would like to delete it and start from scratch. How can I do it without creating issues with git? (I don't see ffmpeg-git in Synaptic)More generally, what is the best way to delete old folders related to obsolete or malfunctioning software, or even unsuccessful attempts at installing software ? Can I do 'delete' in the file manager? or just sudo rm <folder name> ? Or is there hidden issues?Another related question: When manually installing packages not available in Synaptic, for example, from downloaded tar.gz, what is the recommended directory structure. For example, is it better to use, for example: /home/<program name>/source to unpack the source code/home/<program name>/build to build the software?as opposed to using folders in the root directory? Is there a tutorial on the subject of best practice for directory structure?

I tried upgrading from Fedora 8 to Fedora 10 using the DVD, but I ran into a few problems.After verifying the install media, it was no longer able to detect the DVD. Annoying, but I got around this by simply rebooting and then skipping the media check.The second problem happened after I tried to "upgrade an existing installation". It gives me the error "Multiple devices with label /boot detected. Devices must have unique labels in order for you system to work. Please correct this problem before upgrading".My system's working just fine, so I'm not sure why I'm getting this error. I have a RAID-1 setup, so would that be causing the error? How do I correct this problem without wiping out my system?

Question:Several months ago I upgraded my hard drive on a dual boot machine (xp & U9.10 - both 64bit) from approx 80gb to 250gb. I chose to use DriveClone from windows to clone the old drive directly to the new drive. Operational everything works fine. the problem is the Ubuntu HD size went from around 10GB to approx 150Gb, but the filesystem only recognizes approx. 10GB as the total available capacity. I just tried to reinstall Ubuntu without reformatting and only recovered a few GB's. GParted reports the proper partition size. Is there any way I can correct this problem? It's not a big issue...I thought I would check here first before I reformatted the partition. The pre-boot disk check ran and reported no errors but the file system is still not seeing the unused GB's.

I was curious if there is any way to clone my system by simply writing into a file which packages are installed AND deinstalled on the source system.
The reason is that I configured a system which fits me just right (I installed some additional packages and removed some standard packages like OpenOffice...) and was wanting to back it up - even for a newer Ubuntu-Version.
Most of the changes are already gone in /var/log/dpkg.log... so this option does not exist...Does anyone know where Synaptic stores the information which package is installed and which is not? It is possible to view those packages by applying a filter.

I'm looking to move my 10.04 installation from an 80 GB HD to a 250 GB HD.
Last week, I successfully moved a Windows system from an 80 GB HD to a 320 GB HD using Clonezilla. However, I must have missed a command option, as I wound up with only 80 GB used on the new drive, and the remaining space unused. I used PartedMagic to resize the partition to use the full space, and all is now well.
Back to my Ubuntu move, on the second machine, I currently have three partitions - /, /swap, and /home. I'd like to expand / just a small amount, leave /swap sized as it is, and give most of the drive space to /home (as that is where I am running out of space). I think I have two options:
Option 1: Use Clonezilla to clone the drive (3 partitions), and then use PartedMagic to move/resize the partitions as desired.
Option 2: Use PartedMagic to set up 3 partitions to the sizes I want, then use Clonezilla to copy to the new partitions.
Option 1 seems to be the easier way. But, is there another option, a better way? Perhaps there's a command option in CloneZilla that I'm just not seeing, which would allow me to do the move in one step?

I have a DNS server on my LAN at 192.168.140.25. Going by the example in the O'Reilly DNS and BIND book I bought, I set up the domain movie.edu and [URL]. To my great surprise and delight, I can access toystory.movie.edu in a browser from another PC on the LAN (as long as I add 192.168.140.25 to the DNS servers). Encouraged by this victory, I decided to try to set up another subdomain at [URL].
This kind of worked but not completely. Interestingly, I can get to both [URL] and [URL] on my server, but on my PC, I can only get to [URL] not [URL]. Here is my db.movie.edu:
Code:
$TTL 3h
movie.edu. IN SOA toystory.movie.edu. al.movie.edu. (
1 ; Serial
3h ; Refresh after 3 hours
[code]....
