I have a CentOS server that has all of the applications and security settings that I want. I would like to create a bootable ISO image of that server that can be installed across a wide variety of hardware platforms. What are the recommended tools for doing this with CentOS?
View 1 RepliesI have a CentOS 5.5 server that has just recently been updated to 5.6 running PostgreSQL 8.4 and Drupal for an internal website. The server is also acting as a shared network storage between the Linux server and Windows desktops with Samba.
I just recently purchased a license to run Symantec Backup Exec System Restore 2010 for Linux and the only operating systems that are supported are RedHat and Suse Linux.
Does anyone know of a nice open source solution that we can use to create backup images of the server?
In the event of a server crash, we want to be able to rebuild the server via a bit-by-bit backup image.
The CentOS 5.6 is 32bit
I'm trying to set up a virtual machine environment in Centos5.5. My hardware fully supports virtualization, and I'm running qemu as the hypervisor with Virtual Machine Manager as the GUI to manage and create VMs. Host hardware is a Dell PowerEdge T710, with a quad core Xenon processor and four 1TB disks in a raid 6 array.
Within the Virtual Machine Manager when trying to create a new VM, there is the option to not "allocate entire virtual disk now". What format is created when you "allocate entire virtual disk now" and when you don't?
I want to create a qcow2 image format, but it doesn't look like it is supported. Does anybody know how to create a VM with a qcow2 image format?
When you create a blank disk with "qemu-img create -f qcow2 disk.qcow2 3700G", it indeed does create a qcow2 image. However, Virtual Machine Manager is unable to read these images, claiming that it is 15 megs or so in size (which is what it actually occupies in host disk space until you try and put a VM into it).
I'm trying to create new RAM image file to get my server load raid1 module upon start, I was following redhat documentation & it suggested to use the following command mkinited --with=raid1 inited-raid1-$(uname -r).img $(uname -r) However after running this command I'm getting this message No Kernel available for 'inited-2.6.18-128.el5"
View 4 Replies View RelatedI have a problem with the system backup. I need to create a system image using the command "tar", but my server has physical disks with LVM and I am executing "linux rescue" for recovering the linux image. After restoring the image on the new server reports "kernel panic", this is caused because the new server where I restored the image doesn't have LVM disks.

View 3 Replies View RelatedI had set up 4 virtual machines on centos 5.5 system where I directed the image locations to an external storage. I have lost the image files in the storage, but I have the image files that were copied from the virtual machine image location. I want to put up the same system on the same computer by copying these backup images. However, when I copy the image file to the same exact location and start the corresponding virtual machine I get "no bootable disk" error. When I increase the size of the image using "qemu-img" commands, I can get rid of this error, but get "error reading disk" error. Is there a way to overcome these problems, or is it not possible to restore a virtual machine by copying the machine image file under ..../xen/images?

Now im doing it like this:

mkfs -t ext2 -F -m 0 -b 1024 -i 1024 initrd
But i would like to move to cpio, because with dd, if you add something new, you might need to change the count. Also cpio is used in distro's like Fedora and Ubuntu.

View 2 Replies View RelatedAs I understand it creating an image of a Linux system makes an exact copy of the OS and any user files/configurations/programs etc. What i would love to do is create an image of my work PC and install it at home on my desktop. Can someone briefly explain the process of creating and installing images of Linux systems?
Home OS - windows Want - An image file that can be executed in a virtual machine(VMPlayer or VirtualBox) or booted directly on my home PC.
All of my PCs are set up to either run Ubuntu directly, or are dual boot Ubuntu and some variant of Windows. One of the things I like about this is that in the rare instances that I get a virus I can simply boot into Ubuntu and run ClamAV to remove the virus from there.
I have a friend who recently picked up a nasty virus and we are having a hard time getting his machine to boot at all without all sort of strange behaviors. Under that scenario I can't trust Wubi to work correctly. Soo....
Is it possible for me to create a bootable CD, DVD or USB drive from my machine? I'd like to use my machine because I can update the virus definitions before I create the image and then use that to clean his machine.
i want to setup multiple xen on a remote server in a datacenter, this is first time i am doing it, i want to know when we do it on a local machine it asks for bootable DVD to be inserted, but that can't be done on a remote server, so is there a way we can give it the path of some directory which behaves as a bootable dvd and install the os
View 1 Replies View RelatedIs there any way to make a disk image of an active partition? I have to get a complete backup (partitions, MBR, all data files) of my server without bringing it down to do it. I want to have a backup that, in the event of a system failure of any sort, I can quickly restore onto a new, bare hard disk and have the system back up and running. The windows equivalent of this would be something like Drive Image XML, this is the functionality I am looking for.

I'm trying to create some PHP extensions. I have installed php-devel as well as the other preqs I thought were required. However I'm not able to find ext_skel. The file README.EXT_SKEL was installed, but not the actual program (find / -name ext_skel). My understanding was ext_skel was installed with php-devel. I know it is in the source code, but I'm not sure where to get the source for PHP 5.1.6 for my version of CentOS.

I would like to create a customized CentOS server, or it will serve me as a server (postfis) postfixadmin, Hylafax, webmail (Roundcube for example) and may be I would integrate suger crm.
If I create it all this server and it runs perfectly. my goal is I create a compilation or for example I install this distrubution and wonder just some configuration (eg IP address or the time just) knowing that by the end of the installation I find hylafax, postfix , and all AC roundecube install it remains for me to set them up! Taking the example of Elastix cd: www.elastix.org/ or it can make all AC (but its main role is the PABX).

View 1 Replies View RelatedI currently run Windows Server 2008 at my office, but I'm looking to test Samba as a PDC for future reference/consulting work. Before I go and try to configure Samba, I wanted to ask if anyone can think of pitfalls I would run into and perhaps recommend a better setup:
<10 PCs running either Windows XP, Vista, or 7.
VirtualBox running Debian (planning on swapping for Fedora) on a Windows XP Home computer.
Computers are connected to a large switch, which is connected to a wireless router. The Windows server doesn't employ ICS (essentially is just a $1500 PDC ). where I could find a .ovm format image of a windows server installation? I'm guessing vmware would work in this regard, but I'm not fond of using purposely crippled software.
Before installing Centos, I downloaded an image file and burned it to CD using InfraRecorder. It starts to run but does not complete. My machine is a new Intel Q6600 Core 2 Quad CPU with 4G of RAM. It is a 64-bit machine, and I used the 64-bit image. After Centos (which I tried first) failed, I then tried (using the same burning software):
o Slackware
o UBuntu
o gNewSense
o Knoppix
o Debian
o Fedora
o Suse
o BSD
o Solaris
0 puppy Linux
Most failed similarly to Centos. Knoppix worked fully several times, but I was not enthusiastic about installing it, and eventually (on the 5th iteration), it started to fail in a way similar to Centos, and continues so. Solaris and PuppyLinux worked. Those that failed, failed while attempting to start the 4 CPUs. Solaris and Knoppix (when it worked) succeeded in starting all 4 cpus and I could see the messages.
How to communicate what's happening during a failed boot? Finally, I hit upon the idea of photographing the screen during the failing part of the boot; the file is attached. The photo shows the screen just before it blanks, and the BIOS resets for another try. Please let me know if I can collect any other information. I would like to use Centos as a dual boot on my shiny new machine.
Have been playing with Centos 5 and finally got it installed and have done most of the updates. Before I proceed much further it would be nice if I could create a backup/install disc of how it is now. No Data,just the setup and software used etc.Have a dvd rw on the server.I recall mondo rescue installed years ago on a linux server we used.
