Re: [CentOS-es] Clonar Centos 5.6
Buenas, creo que no te queda mas que copiar las configuraciones a mano. El paso de hacer todo en una virtual para después clonar no lo veo necesario, salvo que en el nuevo servidor haya cosas funcionando. Lo de las bases es un dump y restore, no ? El apache es copiar archivos, no ? Lo del tomcat seria tener la misma jvm y copiar el directorio entero, no? Una forma de clonar sin usar vmware seria con tgtd y dd, yo lo use unas pocas veces y ahorra mucho tiempo. Saludos PD: Espero que ya lo hayas podido solucionar...

TLDP's Hard disk upgrade howto is embarrassingly antiquated: when's the last time you saw LILO? When I wrote that How-To, I wanted to copy Linux from a 120 Mb hard disk to a 250 Mb hard disk. I've thought about updating the How-To, but I assumed that modern hard disks are so large that people no longer needed to copy Linux just because they ran out of disk space. Even back then, the How-To wasn't intended for someone who wanted to make several copies. As others have suggested, Clonezilla seems appropriate for your situation: http://clonezilla.org/ I still use LILO to boot from thumb drives, by the way. I feel like I'm speaking to an old friend. =) I did several upgrades with that guide until RH switched to grub. It's been painful ever since. :/ Mostly, I throw in new drives and mount them all over the place. I have systems with a 20 GB / partition with up to 10 TB of drives and partitions crufted all over the place. (yuk!) My issue is that the instructions for LILO don't do much for me with respect to grub. There's numerous howtos mention hdparms and partition numbers and chroot and stuff, but nothing that spells it out for a dolt like me. ... and nobody here's suggested a recommended way to do this. I would *love* it if somebody who knew could ammend your excellent howto with information on grub. (which has been the RHEL/CentOS default for several years) I tried using Clonezilla to clone a 300 GB SAS drive to a 1 TB SATA drive. I don't care *at* *all* if there's some wasted space - I just want it to *work*. But it thew a screen full of random textual garbage on the screen and not much helpful information when I hit the go button. Have you tried dd if=old-drive of=new-drive bs=4096? That may be slow but it usually is the best bet to get an exact copy of the old disk (the new disk must at least have the same size as the old one of course).

Hi, I've got a strange situation where I cannot remove logical volumes even right after they have been created: [root@centos6 ~]# lvcreate -n c6minimal -L+5G vg_nexus Logical volume c6minimal created [root@centos6 ~]# lvremove /dev/vg_nexus/c6minimal Can't remove open logical volume c6minimal [root@centos6 ~]# vgck vg_nexus [root@centos6 ~]# dmsetup info -c vg_nexus-c6minimal Name Maj Min Stat Open Targ Event UUID vg_nexus-c6minimal 253 23 L--w01 0 LVM-rIIS0StztO1tPspxCxiKWJgcmjiufxvXC343e8jObzXGRHbdtvHaHWfh17ZSukm3 I've even gone to runlevel 1 but still LVM claims that the device is open despite dmsetup saying that is not the case. vgck doesn't show anything suspicious either.

[CentOS] MySQL package to install on CentOS/RedHad 6.x
I can see Oracle has packages for RedHad 5 but not for 6... Should I install the rpm for redhad even though they are built against 5?

[CentOS] Two ftp clients? Why?
I had a problem wherein running a script with an embedded ftp call would work in the login shell during integration testing and then fail with an unrecognized option error in cron during acceptance testing. In solving this I discovered that RedHat, and therefore CentOS, ships with at least two ftp clients, /usr/bin/ftp ( which I thought I was using ) and /usr/kerberos/bin/ftp, which I actually was using. even though I had no inkling of its existence. My question is why? Why are there two ftp clients provided in a single distribution and why is the kerberos version effectively made the default whereas one might reasonably assume that anything in /usr/bin/ is the standard ( and by inference default ) ftp client for the distribution? If kerberos ftp is intended to be the default ftp client then why is it not in, or at least linked to from, /usr/bin? I just do not understand why these obscure distribution 'gotchas' are created in the first place, much less permitted to persist. -- *** E-Mail is NOT a SECURE channel *** James B.

It is good sysadmin practice to specify explicit paths for situations like this rather than to worry about whether or not there is a good or valid reason for there being 2 ftp clients installed on the system. Point taken and that is e=indeed what i subsequently did. However, in my defence I explicitly set the PATH variable in the crontab entry prior to invoking the calling script that uses ftp. It never crossed my mind that I should have first done a 'which ftp' to discover which one was being used in my login shell because it never crossed my mind that there would be two different ftp clients on my systems to begin with. And frankly, I do not think that anyone would a priori conceive of there being two separate telnet clients, two different sftp clients, or two of anything else of a similar nature as being a reasonable possibility. 2) Why you are using an ftp client rather than something like wget or curl instead, both of which are far more powerful and script friendly. I tried to use cURL for this particular bit, I in fact use cURL everywhere else in the same script. However, I am unable to determine how to get cURL to give me a meaningful response to the SYST command whereas the ftp client gives me a quite fulsome answer. Presumably the kerberos client only gets installed if kerberos infrastructure is installed, and the standard ftp client is probably part of the default install as people expect it to be there perhaps. Putting in unnecessary logic to only install one ftp client and not the other doesn't make much sense either. Leaving it for an unsuspecting user to discover that there are two dissimilar versions of the same utility is not user friendly. Focusing on finding the best way develop solid solutions to administrative scripting problems like this is IMHO much more important than trying to know or guess what the rationale is behind there being 2 ftp binaries on the system. A rationale is more than I expect. The excuse is likely that it is just too difficult to bother with, as you pointed out above. Anyhow, if you have expectations of specific software being installed or not installed on your systems the only reliable and reproducible way to do that is to use kickstart with a minimal install and build up the package list to include only the things you want to have installed. I expected an ftp client to be installed and I found one in the place I expected it to be. What I did not expect was that there was a second one installed somewhere else on a basic CentOS system with few local customizations and that it was the other client that I was using in my login shell. I am sure that paranoia is a valued admin quality but truly I do not expect to have to run which on every stock utility present on a reputable distribution just to discover if there is a second version of something installed somewhere obscure and stuck into my path by the packager. Nor do I expect that this issue or any like it will ever be considered important enough to comment on by upstream, much less looked at and reconciled. Which essentially is why I dropped RH support and went to CentOS in the first place. But I am pissed that this sort of BS still gets me from time to time. -- *** E-Mail is NOT a SECURE channel *** James B.

The questionable thing is not using entrenched protocols, but using old methods like redirecting ftp commands via STDIN into a client to control it. /bin/sh is an old method. TCP is pretty ancient, as well. For that matter, UNIX is REALLY ancient. Yet somehow, they are not only still useful, but highly relevant. Wheels are also old technology! There are often situations that have special needs that alternatives don't accomodate. For example, a general purpose tool (such as tcp wrappers in a scripting environment) often don't give you the fine level of control that you may need for special needs. Such as, for instance, the web-based product that adds an optional http header to indicate an error condition. Tools like wget or curl don't always allow access to the options needed to access this and so sending stdout thru a pipe to an FTP client might be preferable.

Further, there's two different methods of socket creation, each of which requires special case handling in firewalls at either the client or server side, and this method is chosen by the client, the server has no choice but to support what the client requests, these two modes are known as passive and active.. if you have to use ftp to transfer files, for instance with legacy embedded systems, and you're scripting this, check out lftp, its far more script friendly than the old legacy FTP client. me, I use scp/sftp for authenticated remote file transfers over the internet, and mostly use NFS for internal lan transfers. rsync is useful for incremental updates of a large set of files. for anonymous file serving, I prefer to use http rather than FTP, its just as fast at the raw transfer, and its stateless, so there's less overhead on the server. as an example of lftp, this is my cron job for updating my internal centos mirror /usr/bin/lftp -c 'open ftp://mirrors.kernel.org/pub/ lcd /export/mirror \ mirror -c -x ia64 -x s390 -x s390x -x alpha -x SRPMS centos' (note, I'm not mirroring itanium, system/390, or alpha, nor the SRPMs. My local mirror is in /export/mirror/centos on that system, which is available via both NFS and http on my local network...). -- john r pierceN 37, W 122 santa cruz ca mid-left coast ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Neither rsync nor http have anything to do with M$, they are just well designed protocols. Rysnc is specialized for copying files and directory trees, is normally used over ssh, and doesn't need any extra server-side setup other than ssh keys if you want it to work without passwords. Http is very general and the setup can be as simple or complicated as you want - and it is well understood by firewalls and proxies. Must have a play with rsync though. If ssh works between systems, it will 'just work'. -- Les Mikesell lesmikes...@gmail.com ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Do we have Kerberized rsync yet? Or Globus rsync? If so... please post a link and... (^.^) Anyway, that sort of gets to the heart of just why we have several (not just two) ftp options. ftp, vsftp, Kerberized ftp, gridftp, etc... Its a pretty common tool and in some specific cases scripting the niche ones is necessary due to a lack of alternatives to match a given environment -- though if security isn't an issue (bringing in signed, public packages from a repo, say)... then yeah, rsync; though some people view it as just one more thing to have to learn and never discovering the benefits. -Iwao ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

It takes not even 10 seconds to think of situations where one would need to, such as interfacing with *paying* clients, etc... Yes, if you don't control both ends or you are talking to an embedded device that can't do anything better... *snip* There are reasonable clients for automating ftp (curl, wget, ncftp, lftp, etc.). But they can't match rsync for most things if the goal is to move files around, update them in place, etc. And if you have to traverse firewalls, ftp is about the worst possible protocol to use. I have Proftpd running on my main centos machine. I use gFTP on centos to connect to this machine over my LAN. This allows me to move files between the laptop and the main machine. All my external ports are blocked, and I use ftp as I find the GUI easy and intuitive to use. I would not consider using a commandline ftp client. On my other laptop running Vista I use WinSCP, which is a free GUI ftp client, that allows me to move files from the centos machine to the Vista laptop. Having said that, I can also use my USB flash drive to transfer some files between those laptops and the machine running centos. But it's quicker for me to use ftp over the LAN. One example of using ftp would be me doing some experimental test programs on my (centos) laptop, then ftp'ing to the centos machine and backing up those laptop files to my main centos box's HDD. That way, if the HDD on the lappy goes down, I still have some decent backups on another machine :-) Kind Regards, Keith Roberts - Websites: http://www.karsites.net http://www.php-debuggers.net http://www.raised-from-the-dead.org.uk All email addresses are challenge-response protected with TMDA [http://tmda.net] - ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
