[CentOS] Replacing Multiple Servers with One
We are replacing four servers, running mail, web, ftp, and dns, respectively, with a single server to run all four services. The new server will have a new IP address. It seems fairly straightforward to redirect mail, web, and ftp services to the new server via DNS CNAMES, but I'm not quite sure about how to do the change for the DNS service itself. Is there a need to maintain the old DNS server's IP address during a transition, or longer? Via a virtual IP with the old DNS server's IP address on the new machine, perhaps? Or a second NIC with the old address? Or just have the router redirect incoming DNS requests?

It does not touch the running environment not true, you have severe performance loss and no reliable way to measure the impact of what that changeset is going to bring in. Patching the running system, with a failback option is far better. Unless you dont trust the platform at all. Lack of a reasonable manageable and predictable packaging system can cause that lack of trust. (except to create a housekeeping database for the multiple boot environments). The target boot environment is made bootable, and the the idea of bootable on Linux is limited to the kernel and the initrd ( which even has a shell ). Unless you installed a kernel in the transactino set, there is no need to update grub, since your existing running boot components are still intact ( if not, you can measure and handle it ). If you do update the kernel, the setup will retain multiple copies and your last running kernel is always retained as an option to boot from next boot cycle grub configuration is updated to include the second bootable environment, and the /etc/fstab file on the second environment is modified to reflect the disks/LV's it uses. Take a look at the yum lvm plugin, it already does most of this - with some assumptions on what its going to snapshot and how you want to handle that. The whole idea is not to touch the running system, apply changes to the alternate system, then boot to the alternate when change is done. Once the reboot to the new environment is done, you can further use LU to replace the un-upgraded/un-patched original environment with a copy of the new one. This kind of highlights the issue here, you are attempting to look at this with too far a solaris process mindset. Most CentOS best-practises are driven towards keeping a running system up, by not breaking it or needing to do downtime efforts. Some packages due to their nature will enforce this, like glibc; but on the whole, its considered acceptable to patch live and keep going, with the understanding that there is a failover option / failback opton, rather than assume a running system must be taken down for a patch to be applied. There are exceptions, but most of them are niche implementation driven ones, on the whole CentOS is built to be patched in place. Take a look at the yum lvm plugin on how you can fairly-easily implement the extra step you mentioned ( i.e tweak fstab to boot from a diff lv / uuid ). Thanks to everyone for their replies. I suppose it's not possible in this forum to ask such a question and not get into religion. Kinda like the U.S. Congress. No one has yet shown how a byte-for-byte, fully redundant, bootable disk(set) can be created and kept up to date that will allow immediate recovery from a catastrophic failure of the primary disk(set) with nothing more than a reboot.

[CentOS] Anything Like Solaris' Live Upgrade?
Does anyone know of any sort of Linux utility that does something like what Solaris' Live Upgrade (http://docs.oracle.com/cd/E19455-01/806-7933/index.html) does? In my past life as a Solaris sys-admin, I found this an extremely useful tool for upgrading and patching running systems, as well as for maintaining redundant boot environments on separate system disks for disaster situations. -- Tim Evans | 5 Chestnut Court Linux/UNIX Consulting | Owings Mills, MD 21117 http://www.tkevans.com/ | 443-394-3864 http://www.come-here.com/News/ | tkev...@tkevans.com ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

You also need to manage the grub and fstab configurations to allow the second boot environment to be visible, bootable, and mountable. Are you talking about CentOS? There is no need to change the fstab or grub; the upgrade gets applied on the main volume (where the OS can be upgraded on the fly without a reboot if it works out; or optionally with a reboot if you want to be extra sure). The snapshot is only there if the update goes bad; in which case you'd run the merge command to revert back to the original state. Thanks, again. What you've described is sort of the bass-ackward to what LU does. It creates one or more alternate boot environment(s), then newfs's it, mounts it, copies the running system to it, then applies upgrades/patches to it. It does not touch the running environment (except to create a housekeeping database for the multiple boot environments). The target boot environment is made bootable, and the grub configuration is updated to include the second bootable environment, and the /etc/fstab file on the second environment is modified to reflect the disks/LV's it uses. The whole idea is not to touch the running system, apply changes to the alternate system, then boot to the alternate when change is done. Once the reboot to the new environment is done, you can further use LU to replace the un-upgraded/un-patched original environment with a copy of the new one. -- Tim Evans | 5 Chestnut Court Linux/UNIX Consulting | Owings Mills, MD 21117 http://www.tkevans.com/ | 443-394-3864 http://www.come-here.com/News/ | tkev...@tkevans.com ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

[CentOS] CentOS 6.3 as Firewall/Router
I'm replacing an ancient Solaris 'ipf' firewall/router with a brand new
CentOS 6.3 system. In the olden days, I successfully used the attached
iptables script (as /etc/rc.local) on Red Hat 5.x systems, but this
doesn't seem to be quite working on the new system.
Specifically, while it seems to be routing ok, you cannot connect to
anything on the inside net (e.g., with ssh or a browser) and cannot
connect to the system with ssh or anything else from elsewhere on the
inside net. Yet arp shows this system active.
Is there obsolete stuff here, and/or anything missing that would cause this?
Thanks.

[CentOS] SeaMonkey on CentOS 6.3
Been a while since I used seamonkey, but needed it yesterday. The old version I had installed (2.11) threw an error when I tried it, so I grabbed 2.12.1 from mozilla.com. It throws the same error: $ /usr/local/seamonkey/seamonkey [1] 7050 $ XPCOMGlueLoad error for file /usr/local/seamonkey/libxpcom.so: libxul.so: cannot open shared object file: No such file or directory Couldn't load XPCOM. Of course libxul.so is right there in /usr/local/seamonkey, as it is in the other expected mozilla-related places. Reminds me of the old LD_LIBRARY_PATH issues in Solaris and others. What's the modern way to address this?
