[CentOS] issues with 3rd party repos for centos
i'm reading the lowdown on 3rd party repos with respect to centos here: http://wiki.centos.org/AdditionalResources/Repositories and i have a couple questions and observations. first, the entry for centosplus reads: "Popular packages from this repository include: postfix with database support, a rebuilt kernel with additional drivers & filesystem support, php5 and mysql5." however, i popped over to the centosplus packages site: http://mirror.centos.org/centos-5/5.4/centosplus/ and checked under x86_64, but i don't see any php or mysql packages. am i misreading something? next, regarding remi collet's repo: "Has been recommended on the mailing list and forum for mysql 5.1 and php5.2.9." however, if you check over there (say, under x86_64): http://rpms.famillecollet.com/enterprise/5/remi/x86_64/repoview/development.languages.group.html remi appears to already be up to php 5.3.1 (and even 5.3.2 under the "test" link), so the centos wiki page is a bit out of date. finally, all i want is to install PHP 5.3.x (and, obviously, dependent packages) on a stock centos 5.4 system. is remi collet's repo a good choice for that? the centos wiki recommends "extreme caution" for that repo, which makes me nervous. more to the point, are there any serious issues involving bumping up php to 5.3.1 on a stock centos 5.4 system while leaving everything else where it is? rday -- Robert P.

I've run the ocsinventory-server from remi repo for a while, letting it pull in the msyql and php versions from there (and I think you also need epel enabled for additional dependencies). It hasn't broken anything obvious. I keep the repo disabled in the yum setup and explicitly enable it with enablerepo=remi on the command line when updating ocsinventory. >more to the point, are there any serious issues involving bumping up > php to 5.3.1 on a stock centos 5.4 system while leaving everything > else where it is? That probably depends on what php-based apps you need to keep running. Nothing else should care - but you do have to pay attention to what other package updates might be pulled in when you do updates. I usually do an update without remi enabled first, then with, and look over the list that it plans to install before accepting it. -- Les Mikesell lesmikes...@gmail.com ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

[CentOS] Success moving Xen LVMs from 32 to 64bit host
Just wanted to share some success I had moving some Xen guests from one server to another. Problem Recap We had Xen host on a single core 32-bit CentOS 5.4 installation on an AMD Athlon 2.1 GhZ system that was giving hard drive errors and needed to move the LVM-backed Xen images to another server. The replacement server was a quad-core AMD Phenom system running 64-bit CentOS 5.4. Our original plan was to use LVM snapshots so that we wouldn't need a maintenance window. This worked fine in test, but we decided to bring down the Xen guests after all. After shutting down the systems we backed up the LVMs. To show the backing LV: lvdisplay /dev/rootvg/xm_c32_001 >From this, we grabbed the "Current LE" field and LV Size. We used LV Size to create a temporary mount point. We used the "Current LE" parameter to create an identically sized LV on the replacement server . On the failing server: dd if=/dev/rootvg/xm_c32_001 of=/mnt/backup/xm_c32_001.out We gzip'ed the resulting .out file and saved it as a backup. +++Footnote BTW, there are many recommendations to do the following on the virtual machine: dd if=/dev/zero bs=1024 count= of=/partition.out rm partition.out By creating the large empty file on each partition *in the guest istance* (/var, /, /home, etc.), it will improve the image compression. Space was not much of a concern and we were worried about blowing out a production system, so we opted not to do this. +++Footnote Once the backing LVM was created, we created the LV on the replacement server: lvcreate -l xxx -n xm_c32_001 rootvg Then used dd to recreate the file: dd if=xm_c32_001.out of=/dev/rootvg/xm_c32_001 Next, we copied the /etc/xen/xm_c32_001 configuration file to the replacement server. We generated a new UUID using the "uuidgen" utility. We also created a new MAC address. Finally, we started the instance: xm create xm_c32_001 Everything came up, but no network. From the root console we logged in then edited the /etc/sysconfig/network-scripts/ifcfg-eth0. Xen had apparently renamed the script and put in a DHCP configuration. We just renamed the backup file and commented out the MAC address line and restarted networking, *and* ifdown eth0 then ifup eth0. It took a few seconds for the network to properly discover the new MAC address. Once that was done, everything worked beautifully. ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

[CentOS] Moving hard drives
Hi All, I have a server that is running nicely, except I have hit the maximum RAM (4gb) and I wish to add more. It is an ASUS board, AMD X64 dual core, nvidia nic. What I want going to move to is a dell board, Intel Pentium M dual code, which supports 8gb of RAM. Can I just unplug the HD and move it to the new server and boot it up? I assume that the NIC will need to be re-setup, but what other issues would there be? I am not running X at all. Doing apache, zimbra, mysql.

Rsync over ssh doesn’t works but a little cumbersome – customer’s servers’ data center are far away from development site and link between is slow. So better one to data center’s one and from the latter to all others in data center. This will work better but still could be improved. Since customer has some scripts to be reloaded after codes/data are synced. >You'd probably really want to wrap this with a version control system like >subversion to get history, logging, rollback capability, etc. so Is there already an existing solution like this available, open source and commercial?

Once installed, take a peek at the kernel parameters. If you see anything markedly different, just add a stanza to the old system with the parameters from the test installation before shutting it down.

Truth be known the Asus board is faster even with the less ram. Are you sure the Asus board only supports 4GB and not 8GB? > Can I just unplug the HD and move it to the new server and boot it up? Gee I wish it were that easy. It's not MS Windows.

There are a lot of things called 'content management systems' that are basically web sites with upload/management capability built in (joomla, drupal, alfresco, etc.). They aren't likely to work unless you start over from scratch with them for the web site design. If you already have the sites in place you are probably better off setting up a subversion repository and a staging site at the data center with the servers (perhaps even running on one of them) and let the customers commit the changes to the repository with subversion client tools and work out a script that checks out a revision they specify into the staging area, rsync's to the server locations, and ssh's the needed commands. The operations should be relatively simple and as easy to manage in shell scripts as some dedicated framework. -- Les Mikesell lesmikes...@gmail.com ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

What flavor of hard drive controller? If generic IDE, yes. If SCSI or SATA (or 'fancy' IDE), only if the original and replacement use the same driver module (if a PCI SCSI card, move the SCSI controller with the disks). If the controller is *different*, remake the initrd and add the proper driver for the replacement board: mkinitrd --with= -f /boot/initrd-`uname -r`.img `uname -r` is the driver module for the new board's HD controler. (Do this on the original system.) You can use a livecd to determine that. You *could* just do the transplant and then use the install CD (or a live CD) in rescue mode to 'fix' the initrd. > > I assume that the NIC will need to be re-setup, but what other issues would > there be?

Doing apache, zimbra, mysql. If you're worried, use a tool such as g4l to make an exact duplicate of your system. You boot with the G4L disk then clone the HD to an external HD or a network accessible share. Then boot the new with the G4L disk then reimage the drive from the backup. The ease with which this is done is all relative. Unlike MS Windows, which can have lots of problems when moving to a new system, Linux installations generally move quite easily. In fact, the initrd on CentOS contains many generic modules so at worst case it can often fall back to a compatible module. To inspect the initrd you can copy the existing initrd.img to file such as foo.img.gz, gunzip, then use cpio to extract the foo.img file. Once you do that you will see the many modules that exist. Going from ATA to SCSI or SATA will have some issues, generally with fstab but that's to be expected. Other than that, no real problems.
