[CentOS] Help! i want to clone my Centos machine to another box..

[RoLaNd RoLaNd]

Hello all,

i've spent the last week trying to find something that will clone my existing 
Centos server to a more powerful box.
i've used clonezilla though that resulted in a complete failure..

can anyone please guide me in the right direction? 
all i want to do is to clone my entire server and all of it's directories to a 
more powerful server so i start using it instead..
i dont want to get rid of the current server as i want both of them to run in 
parallel with the same backed up services/data on each of them..


can anyone please help! im honestly desperate!! 


best,

Roland

Just in case it is not clear to you. cpanel is NOT Centos. It is a very 
badly modified version of Centos and we have nothing to do with it. 
Please take any issues you have with it back to Cpanel.

So long as they are running pure Centos, your questions are welcome 
here. If it is on cpanel systems, please take it elsewhere.

When I've upgraded a kernel on CentOS, the previous kernel(s) is/are not
removed and in fact remain part of the boot menu, albeit not then the
kernel(s) booted by default.  E.g.,

cat /boot/grub/menu.lst
...
title CentOS (2.6.18-164.2.1.el5.plus)
root (hd0,2)
kernel /vmlinuz-2.6.18-164.2.1.el5.plus ro
root=/dev/mapper/luks-3d723b4f-0184-438d-9cb9-9ebff16e683a rhgb quiet
initrd /initrd-2.6.18-164.2.1.el5.plus.img
title CentOS (2.6.18-164.el5)
root (hd0,2)
kernel /vmlinuz-2.6.18-164.el5 ro
root=/dev/mapper/luks-3d723b4f-0184-438d-9cb9-9ebff16e683a rhgb quiet
initrd /initrd-2.6.18-164.el5.img
title CentOS (2.6.18-128.7.1.el5)
root (hd0,2)
kernel /vmlinuz-2.6.18-128.7.1.el5 ro
root=/dev/mapper/luks-3d723b4f-0184-438d-9cb9-9ebff16e683a rhgb quiet
initrd /initrd-2.6.18-128.7.1.el5.img
...

If your /boot/grub/menu.lst is similar, then you need only select a
previously installed kernel at the boot menu.  You can access this via
your remote KVM setup, yes?

In the past I've edited menu.lst to change what's booted, i.e., I
rearranged the order of the stanzas to make the first one, which is the
default (the one booted if no action is taken at the boot menu), the
working/desired kernel.

Since the destination machine is "more powerful", the hardware is likely
different, so cloning per se isn't an option.  Instead, you should do a
fresh install of the same version on the new (destination) box, then
copy the data over from the weaker to the destination machine.

There are a variety of options for copying the data.  Since it sounds
like there's some pressure at the moment, the best way for you now is
going to be the method you're most familiar with.  Do you have good,
recent backups of the source system?  If so, you could restore that
backup to the destination machine.  Otherwise (if your two machines are
both on the same network), you could use tar or rsync or yet other
utilities.

[CentOS] Missing yum-priorities in 5.4?

[Morten Torstensen]

I am looking for yum-priorities or any info on any changes here for
CentOS 5.4. There is also a forum post for this here:


Is this missing on purpose? Function merged with another yum package?

Thanks for the hint: I did it (I'll spare you the listing). The
-164-kernel ist the first one where according to "rpm -qf " the
module is "owned" by the kernel package. All the other instances of
xfs.ko point to a module "owned" by kmod-xfs.

So obviously I'm not using the kmod-xfs anymore (I'm relieved that the
last kernel-update worked without a clash)

Thanks again for clearing that up

I just upgraded a few systems with v5.4, rebooted and then ran an update
again. The yum-priorities plugin is loaded and used with the regular "yum
update" command. 

Or am *I* missing something here? I don't see anything wrong...

To the CentOS-devs I'd like to extend a great thank you. The v5.4 upgrade
went in w/o a hitch and seems to be working excellent.

So can I just copy the RPM from my 5.3 to my 5.4 and all will be good?
  No need to makerepo or anything?

[r...@alan centos]# find . -name yum-prio\*
./5.3/os/i386/CentOS/yum-priorities-1.1.16-13.el5.centos.noarch.rpm
./5.3/os/x86_64/CentOS/yum-priorities-1.1.16-13.el5.centos.noarch.rpm

Just copy those to the same spot under 5.4?

An upgrade should do fine, I think... the yum versions in 5.3 and 5.4
looks to be the same, so nothing would be uninstalled afaik.

Looks to me that you will only see this when you do a fresh install of 5.4

Ditto.

The problem is not with updated systems but with newly installed systems. 
yum-priorities is missing from newly installed 5.4 systems. It's fine with 
updated systems.

For MySQL backups I use the mysqldump utility, which dumps the data as
pure SQL.
This may not be the best option if you have a huge amount of data though.

http://www.microlinux.fr/configurations.html

The shortcut on the lower left corner of the screen launches the public 
library management system.

Most of the users are quite computer-illiterate, and more often than 
not, they tend to erase these shortcuts (and then call me panic-stricken 
at 07:00 in the morning :oD).

To configure the shortcuts themselves, I just edit a .desktop file by 
hand. I tried various combinations of chown and chmod, but to no avail. 
Even if there are minimum access rights, the thing can still be erased 
with a right click.

Now I vaguely remember that a standard openSUSE install has something 
like persistent desktop shortcuts (for the SUSE help center or something 
like that), and I wonder: how do they do it ?

Any suggestions ?

Yes, but since the CentOS team puts out the effort to mirror the docs,
I'm sure that everyone involved would prefer that things work correctly.

Don't forget htat you can use the default command in the grub.conf, e.g.
"default 1", rather than rearranging all the time.

Use "info grub", select the "index" entry and then look for "default"

Sendmail demands a dotted hostname in /etc/hosts for itself. "localhost"
is not enough. "localhost.localdomain" (which is even the CentOS default
for 127.0.0.1) works.

It is rare for files to be locked on Linux when in use, so you probably won't 
get permission denied errors.  However, if files are changing while you copy 
them you will get a bad copy.  One approach is to do one rsync with the machine 
running normally, then repeat with most of the services stopped.  The 2nd pass 
will go very quickly since it only has to copy the changed files.

If mysql isn't running and you are copying to the same type of machine (32/64 
bit) you can copy the files directly.  Otherwise, msqldump is the way to export 
(and what you should be using regularly for backups).

> 2. anyway of copying user permissions and passwords? or i have to create

You'll have to work through the files in /etc by hand, since some relate to the 
hardware and some to the configured software.  If all the installed software is 
the same on the new system you can probably just copy /etc/passwd, /etc/shadow, 
/etc/group, and /etc/gshadow but a safer approach is to keep the uid's below 
500 
from the new system and edit in the higher ones from the old.

I'd either copy the old /etc tree to some other location on the new system so 
you can diff and pick out the useful parts or change the old system's name/IP 
so 
you can access it until the new one is completely working.

I've always thought that linux distos badly needed a 're-install' function to 
adapt a clone/backup copy to new hardware. Most of the knowledge of what has to 
change is buried in anaconda - although you have a fair chance of making it 
work 
if you boot a rescue CD and rebuild the initrd with the modules that are set up 
when you do an install on that machine.

What version of XFS is supplied?

Is it still true that RH doesn't supply xfsprogs and xfsdump so we  
need to use the ones in 'extras'?

If so, wouldn't it be risky using the RH supplied kernel driver with  
third party supplied maintenance apps in case RH were to backport any  
XFS internal structs that the user progs don't know how to handle, or  
vice versa.

I think I'll stick with the complete CentOS XFS bundle for a while and  
see what RH does.

Agreed. The reference to cPanel in this thread makes no sense.  As for
wanting to contribute to the CentOS Project, there is some information
available on the Contribute page of the CentOS wiki [1].  That's a
good place to start.

Look under /usr/share/(apps,applications,...) there should be a  
directory called Desktop that is used for both KDE and Gnome, part of  
the freedesktop initiative (like LSB for Linux GUIs).

[CentOS] Missing virtio-win in CentOS 5.4

There are freely redistributable, but still they aren't published by upstream. 
You 
can use these instead: 
http://www.linux-kvm.com/content/windows-binary-virtio-drivers-finally-released,
 but 
there are a lot of problems with any windows 64 bits. And another problem, a 
big 
really, is that you can¡t install a windows kvm guest directly to a virtio 
disk. 
First you need to install to an ide disk, after generate a virtio disk and 
attach to 
win guest, install the virtio driver and last remove ide drive ... very very 
ugly.

[CentOS] CentOS-5.3 yum-priorites

[James B. Byrne]

I visited http://wiki.centos.org/PackageManagement/Yum/Priorities
which tells me to install the package yum-priorities available from
extras.  I try this and it fails.

# yum install yum-priorities

So, where has it gone?

   1. Release for CentOS-5.4 i386 and x86_64 (Karanbir Singh)


--

Message: 1
Date: Thu, 22 Oct 2009 02:44:07 +0530
From: Karanbir Singh 
Subject: [CentOS-announce] Release for CentOS-5.4 i386 and x86_64
To: centos-annou...@centos.org, dis...@distrowatch.com
Message-ID: <4adf799f.9020...@centos.org>
Content-Type: text/plain; charset=ISO-8859-1; format=flowed

We are pleased to announce the immediate availability of CentOS-5.4 for 
i386 and x86_64 Architectures.

CentOS-5.4 is based on the upstream release EL 5.4.0, and includes 
packages from all variants including Server and Client. All upstream 
repositories have been combined into one, to make it easier for end 
users to work with. And the option to further enable external 
repositories at install time is now available in the installer.

This is just an announcement email, not the release notes. The Release 
Notes for CentOS-5.4 can be found on-line at :
http://wiki.centos.org/Manuals/ReleaseNotes/CentOS5.4 and everyone is 
encouraged to look through them once. Also worth browsing through at the 
CentOS FAQ's at http://wiki.centos.org/FAQ

+++
Upgrading from CentOS-5.3 ( or CentOS-5.0 / 5.1 / 5.2 ):

If you are already running CentOS-5.3 or an older CentOS-5 distro, all 
you need to do is update your machine via yum by running :

'yum update'

Running 'yum list updates' before doing the update is recommended, so 
you can get a list of packages that are going to be updated. To check 
you are indeed on CentOS-5.4, run : 'rpm -q centos-release' and that 
should return: 'centos-release-5-4.el5.centos.1'


+++
LiveCD i386

For the first time, we are also releasing the i386 CentOS-5.4 LiveCD at 
the same time as the main distro. There will be a separate announcement 
with details of changes in the 5.4 LiveCD

+++
LiveCD x86_64

Also for the first time, we now have a x86_64 CentOS LiveCD. This 
release includes support for both 64bit and 32bit user-space. However, 
due to size issues will only burn to a large capacity CD-r. There will 
be a separate announcement with details for the x86_64 LiveCD.

+++
Downloading CentOS-5.4 for new installs:

When possible, consider using torrents to run the downloads. Not only 
does it help the community and keeps mirrors from running up high 
bandwidth bills, in most cases you will find its also the fastest means 
to download the distro. There are present over three hundred people 
seeding CentOS-5 and its possible to get upto 100mbps downloads via 
these torrents.

-- Via direct download:
Due to bandwidth considerations the CentOS Project does not publish ISOS 
directly from our network machines. However direct downloads are 
available from external mirrors over http, ftp and rsync, and a geoip 
based list is available at http://isoredirect.centos.org/centos/5/isos/ 
to give you the best predictable match ( and only lists mirrors that are 
updated already, so you don't need to waste time looking for a sync'd 
mirror )

 Some mirrors also publish DVD images that can be downloaded 
directly. Refer to the mirrors list page at 
http://www.centos.org/mirrors for more details Mirrors that offer DVD's 
are clearly marked on the page.

 Now what are you on about, are you posting to the wrong thread per chance?

Where in his post did he mention "Calling all Hackers"? Are you

[CentOS] Way to go, CentOS team. Here's a hearty "thank you"!

[Gilbert Sebenste]

Hello all,

To the CentOS developers, beta testers, and all who were involved in a 
small or major way in the release of CentOS 5.4...thank you. Ignoring the 
peer pressure, even though it was out a little later than you (and many of 
us) wanted, you got it RIGHT. *That* is what was important. I yum updated
from 5.3 to 5.4 with NO issues that I can speak of right now.

Thanks to you fine folks, and of course, the upstream vendor, for doing a 
fantastic job!

[CentOS] LDAP server, too many open files

[Jacob Bresciani]

I've setup an LDAP server with a slave server on Centos 5.3 X86_64,  
replication works, most of the time client logins work fine but I'm  
starting to get a error I can't seem to eliminate, it's starting to  
cause login failures for users and I think it's causing other  
application failures when they try to auth against ldap.

on the client side /var/log/messages shows
Oct 22 08:53:23 client sshd[564]: nss_ldap: failed to bind to LDAP

This seems to conflict with the release notes
(http://wiki.centos.org/Manuals/ReleaseNotes/CentOS5.4) which recommend
this procedure:

yum clean all
yum update glibc\*
yum update yum\* rpm\* python\*
yum clean all
yum update
shutdown -r now

You probably are running into the default limit for open files. Look at 
/etc/security/limits.conf and add a line reading

*-   nofile  64000

Then restart the ldap server via the init script.

Re: [CentOS] Help! i want to clone my Centos machine to another box..

[R-Elists]

roland,
 
what i recently did was use this info and modified the backup-servers script
slightly
 
http://www.jms1.net/code/rsync-backup.shtml
 
it was really simple to move a live centos4 from one machine to another
after admin down services that would allow data to change on the final rsync
pass.
 
one machine was an older compaq DL380 and the new machine was a HP DL360
 
basically i did a centos 4 load on the new machine and paid careful
attention to what needs to be excluded as well as changed before and
afterwards
 
things like  /etc/modprobe.conf
 
then change ips and reboot.
 
the having two servers side by side thing is a different set of
circumstances and setup...
 
we just cloned one to the other and took the original machine offline.
 
if you have a lot of linux experience and cannot figure out the step by
step, post what you did to "try" and accomplish it and then we can help more
later
 
please be specific in your postings

Thanks, I've put in that change, I'll get the dev's to abuse things  
for a while and we'll see if that's it. quick tests by me look  
promising :)

I know too that  yum - -security doesnt work on CentOS, so there is no way

Just run yum update and you'll get all of the updates that
you need that are available.

Except that you'll probably end up with 5.4 or maybe an incomplete 
update if you do it while the mirrors are still syncing.

All, that is "yum update" with a standard configuration (note that "All" 
here 
includes updates all the way to 5.x latest (which, as of about now, is 
5.4)).

does not work on CentOS, never has. However, it *should* start working

[CentOS] IPSec VPN Under CentOS 5.4

[João Salvatti]

Hi List,

What's the best way to create a VPN (IPSec) client-to-site under CentOS 5.4?

Thanks in advance.

the best way is to use ssl-vpn rather than ipsec, via OpenVPN.  Its a 
breeze to install and configure compared to most any other VPN, quite 
easy for the server to push routing rules to the clients, etc.

I'll second the OpenVPN reco, I just migrated off a Cisco PIX to this
and it is the most configurable, and stable thing I have seen in ages.
I have connections from both Linux and Windows machines that sustain for
several days without a single hiccup whereas the PIX would often suffer
from non recoverable transient errors that tanked the connection.

Openswan is your friend.  I have it running (under OpenSUSE) and it is

On the other hand, if you don't have a strict requirement for IPsec, it is much 
easier to get the udp or tcp packets that work for openvpn through NAT and 
port-forwarding routers.

I second this.

IPSec also has another advantage over SSL as it is compatible with
non-linux devices (Cisco etc) which don't have support for SSL based
VPNs, and is just as (if not more) secure.

True for port fowarding, but current versions of Openswan (that is,
currently available in most public repos) work just fine with NAT.  I am
using it in NAT environment and I did not have to make NAT/Masquerading
adjustments.  This was not always the case, and the Openswan docs still
refer to adjustments for NAT networks... but as I said it works just fine
for us without adjustments.

Macs work well too in an OpenVPN environment. You can compile it up 
yourself (or via MacPorts) or use Tunnelblick:

   http://code.google.com/p/tunnelblick/

Note that OpenVPN and Vista aren't necessarily quick to work and play 
well together. They can do it, but some coaxing is often necessary. 
XP, otoh, works great.

On Linux, I like running OpenVPN as a standard daemon, but there's 
also a NetworkManager plugin that mostly works as advertised.

Re: [CentOS] Help! i want to clone my Centos machine to another box..

Acronis, with a little SALT and PEPPER may do the trick.

However after running acronis you would have to do an OS Repair.

Sorry, that is for windows.

CentOS on the other hand should be able to CLUSTER.

Why not try to cluster it instead

If I had to clone a machine, I would.

1) Use G4U (Ghost 4 Unix)

2) Boot PartedMagic on the target machine and perform and eventual disk 
resize.

3) Run Kudzu on the first bootup, then eventually configure odd bits by 
hand.

[CentOS] CentOS-5.4 Update?

[James B. Byrne]

hdwr HPQ DC7700S ix86 Core Duo

I have just updated this CentOS-5.3 box to 5.4.  This process was
not satisfactory.  While the update packages all downloaded without
problem the update process itself stalled at several points.  By
stalled I mean that at some point the entire process stopped for
hours. The packages at which it stalled included evince, evolution,
totem and vinfo.  There may have been others but these I seem to
recall.

Restarting the update process required that the existing update be
interrupted with a C and yum-complete-transaction run.  It
took five iterations to get through to completion and in the end I
first installed all the remaining packages one at a time directly
from the command line using yum install packagename and then ran
yum-complete-transaction until all outstanding transactions were
cleaned up.

Now, while the system boots I have no gnome desktops for any of the
users on this host.  When root logs in all that is shown is a deep
blue background and a wirefram outline of the Firefox web browser, a
wire frame outline of an xterm window and an analogue clock.  Left
clicking on teh background displays a popup menu labeled "Tvm".

The mouse and keyboard work and when one clicks on the wireframs
then immediately fill with the application background, the CentOS
welcome back for FireFox and a black on white scheme for xterm.  All
the windows have teal menu bars.  Further, it seems that I cannot
switch between windows.  If I try to enter a command in the xterm
window then what I type appears in this compose window for
squirrelmail.

I would like to get my previous customised desktops back, but first
I would like to get the default to display. Are there any ideas on
how to proceed?

Sincerely,

On a hunch I did a 'yum list gno\* | more' and discovered that
gnome-session was not installed.  Installing gnome-session, as you
may imagine, solved the problem of the missing desktops.

Now the question is: how it is that an update can remove the
gnome-session package without first installing its replacement, if
indeed gnome-session was part of the update at all?

[CentOS] [SOLVED] CentOS-5.4 Update?

On a hunch I did a 'yum list gno\* | more' and discovered that
gnome-session was not installed.  Installing gnome-session, as you
may imagine, solved the problem of the missing desktops.

Now the question is: how it is that an update can remove the
gnome-session package without first installing its replacement, if
indeed gnome-session was part of the update at all?

Sincerely,

You used the CloneZilla Live CD?

CloneZilla Server and DRBL Server are entirely different and can be
difficult.  But CloneZilla _LiveCD_ is easy.


Tell us more about your RAID config.  It is not software raid is it?
Not sure if any cloning system can work to clone software raid unless
you have completely identical set of drives in both and then you would
not be doing disk level cloning, but file level cloning.
What kind of raid do you have?

[CentOS] Firefox keeps crashing after 5.4 upgrade

I've almost never had crashes before this, and it has been 3 or 4 so
far today after my upgrade.   Could it be one of my plugins I suppose?

You don't use root's password, you use your own password.

This assumes you have an entry in /etc/sudoers for your account.

I can't answer your question, but out of curiosity, did you just do a simple 
yum 
update or did you follow the procedure in the release notes document?

[CentOS] Upgrading CentOS 5.3 from local mirror

[Jonathan Moore]

Good afternoon folks.

Earlier today, I started upgrading a few of our servers to 5.4 based
on input from the list.  So far, all has gone well.   I have about 6
servers (not very many, but still) that need to be upgraded.  Instead
of taking precious bits from the mirrors for each upgrade, I was
curious if I could rsync the 5.4 directory from a local mirror, and
configure yum to use that repo, if it would upgrade without issues?

Would I need anything other than the 5.4 folders to do the upgrade?

Ok, I use KDE at work and by putting .desktop items in /usr/share/apps/ 
kdesktop/Desktop the icons are global to all desktops and can't be  
removed.

How you do it in gnome, I haven't a clue, but it works in KDE.

[CentOS] upgrade to 5.4 openswan broke

[Myron Williams]

Hi All,

I upgraded from 5.3 to 5.4 today on a vpn gateway using openswan.  After
the upgrade the vpn stopped working.  From what I could tell the new
version of openswan uses NSS.  I tried following the instructions in
this thead https://bugzilla.redhat.com/show_bug.cgi?id=508107 without
success.  

  # certutil -N -d sql:/etc/ipsec.d
certutil: function failed: security library: bad database.

If I ran the command without the sql: like this
  # certutil -N -d sql:/etc/ipsec.d
it would create the database files.  
I would then execute
  # modutil -fips true -dbdir /etc/ipsec.d
followed by
  # /usr/sbin/ipsec newhostkey --configdir /etc/ipsec.d/nssdb
--password password1 --output /etc/ipsec.d/host.secrets
After replacing the hostkey in the file I tried to bring the connection
up but the connection would not start and the following error message
was in the log file.
   unable to locate my private key for RSA Signature
   sending notification AUTHENTICATION_FAILED
I finally had to downgrade from openswan-2.6.21-5.el5 to
openswan-2.6.14-1.el5 to get things to work.

Am I missing something that is needed to make this work?

Any help would be appreciated.

Myron Williams

sudo expeccts your USER password, not the root password.   the whole 
idea is the admin doesn't ened to give out the root password to give 
controlled admin privs to a user.

Goood John,
But you please also clarify what does sudo means;

if it expects my own password then why not i can execute these command
without giving "sudo" as prefix.

If i am a genuine sudoer then can i edit files on which only root has
execution rights.

Because sudo is the program that gives you the rights to execute certain
commands as root without actually being the root user.  If you don't run the
program "through" sudo, you won't get the rights.

> execution rights.

If you have the relevant permissions set in sudoers, then the answer is yes.

The whole objective of sudo is to allow some users to do certain things that
could otherwise be done only as root, without actually allowing the user to
become root.

In short, sudo allows you to set things up so a certain user can execute a
specific list of commands as root, but can't execute other commands as root.
The list of commands that you allow that user to execute is determined by the
sudoers file.
