I've used Unix/Linux at Wright-Patterson AFB, USA since 1988 -- this includes Solaris starting at 2.5.1 up to 11, FreeBSD, and Linux.

I *despise* Oracle the company, but I ran Oracle Linux as both a server for an Oracle DB and as my workstation starting Jan 2018 after a drive failure knocked my machine out of the park. Occasionally I had to dork around looking for a source RPM, but other than that I was fine with it. You use "yum" like anywhere else. FWIW, my 6.10 installation had this in /etc/redhat-release: Red Hat Enterprise Linux Server release 6.10 (Santiago) Go to https://linux.oracle.com/switch/centos/, poke around a bit, and you end up here: https://yum.oracle.com/oracle-linux-downloads.html I just went to the ISO page and I can grab whatever I like without signing up for anything, so nothing's changed since I first used it.

Backing up maildirs doesn't require any downtime because a maildir is atomic in every way that matters. It uses filename and location to indicate message status. If you want to back up *live* Maildir folders, either one of these will do: http://code.google.com/p/maildirsync/ http://syncmaildir.sourceforge.net/ Unless your users are in the habit of editing messages, Maildir files don't get modified; they're created, renamed and deleted. When users do edit messages, the mail client normally creates a new one and deletes the old one. As a result, rsync isn't the most efficient way to sync maildirs -- when status changes occur, rsync sees that a new file exists and an old one is gone. It doesn't know that the file was renamed. The only real issue when backing up a Maildir using tar/rsync is speed. Neither method is great when backing up a large number of small files, as many people have observed in the past. Common workarounds: * using dump/restore (requires a quiescent filesystem), or * using tar/scp for the first Maildir backup and using rsync afterwards. All you need for this case is an SMTP server that understands Maildirs. Contrast this with an RDB, where you absolutely need consistent and quiet files to do a successful backup. If you want DB replication, then you need: * an SMTP server, plus * an RDB on the mailserver, plus * a replica of the DB on another server.

It sounds like your best bet would be to change the source for su, and just be prepared to reinstall it if/when yum (or whatever) replaces it. Being able to specify the default PATH without having to mess with shell setup files is a nice feature; Solaris allows you to do this by providing an /etc/default/su file to set the PATH plus other things like whether you want to use syslog for access logging, etc. Why not change the production version to use (say) /etc/sysconfig/su for the default PATH?

Re: [CentOS] your advice on backup procedure
On Fri, 23 Mar 2012 20:19:41 -0400, Bob Hoffman b...@bobhoffman.com said: B I am down to my last hurdle of my project, backups. Not asking for 'how B to' but more of 'what is best in your experience'. Some questions: * What's the hardest stuff for you to recreate? I'd have that on both DVD and something network-accessible. * What's your biggest PITA problem (for me, it would be bare-metal restore) vs. your most likely one (I'd assume loss of a MySQL table or a VM)? You mentioned being able to rebuild the host quickly, so if the bare-metal thing isn't a big problem, concentrate on the VMs instead. * What are your priorities? If it's speed of the restore, and you have the IO/network bandwidth and room, then do like another poster said and rsync the VM files after shutting them down. If it's more like history where you want to go back in time to lots of versions, something finer-grained would be in order. B The scenario... centos server acting as a virtual host. Virtual B machines are webservers and dns servers. All on one machine, all running B centos 6. Virtual machines are kvm, sitting in lvm storage. What I B want to do.. auto backups of the virtual machines to be stored on the B virtual host's extra drives for later download to my home computer. Your VMs sound like they start out identical, and then you add stuff to specialize each one. If so, I'd keep these backups: a. one generic bare-bones VM that can be installed with as few commands as possible. b. each change-set you use to specialize for basic DNS, web, etc. c. smaller groups of individual files like DB schemas, web content, mailboxes, etc. This way, any given restore breaks down to (a) plus (one or more b) plus (whatever's appropriate from c). When you get to the individual file backups within a VM, something like this might be all you need: # cd / # find . -depth -type f -newer /etc/BKUP -print | pax -x cpio -wd | gzip -c /path/to/$(date '+%Y/%m%d/%H%M').pax.gz # touch /etc/BKUP B 1- Amanda. I do not know much about it or how it would deal with mysql B databases, but it look promising. I set it up once, but it wasn't a close enough match to what we needed for me to craft an entire backup strategy around it. It's not a trivial thing to install or run, so you'll be spending time finding out how Amanda wants to do things and matching that to your goals. B 2- rsync - some kind of rsync going from the host to each machine, B putting it on the host's backup drives. That's what I use at work, but we're closer to the networked fileservers with remote shares setup. I use the find/pax/touch setup above to handle hourly backups for 800-1000 users, and they're happy little campers when they find out the spreadsheet they created at 6am and mangled around noon isn't completely gone. -- Karl Vogel I don't speak for the USAF or my company Texted a friend meaning to ask if she was busy.
