mysql secure installation and multi mysqld
by Bob Hoffman 17 May '12

17 May '12

If you adjust the my.cnf file to make separate instances of mysql..... How would you go through the mysql secure installation? Is is possible or must it all be done manually for each one? is it possible to make each one of those instances a replicate/slave of a different master (thus a backup mysql server in a way?) working on this now, but having issues getting it to work.

Notes on booting CentOS 6 natively on GPT with an EFI bootloader such as Chameleon without BIOS GPT/EFI support.
by Lamar Owen 16 May '12

16 May '12

Ok, did some experiments. Here's the scoop. You will need a live USB key of CentOS 6 with a persistence layer (overlay) and the EPEL gdisk package installed to make this thing boot. On a system with Chameleon already installed, boot the CentOS 6 install media. Installing Chameleon without OSX is an adventure that I've not done, so a 'testing' OSX install (10.6) with the Chameleon bootloader installed was used; once Chameleon is in the EFI boot partition in theory you can blow away the HFS+ OSX filesystem, but I've not tried it. This involves partitioning the disk as GPT, and there are numerous howtos out there for many motherboards and laptops; the key is to get Chameleon in the MBR and the EFI boot partition properly created, set up with a protective MBR, and populated. Install to the free space on the system, using a /boot of about 500MB, swap space to taste, and other filesystems as you like. When the install prompts for bootloader installation location, you DO NOT want to install to the MBR (Chameleon is there); rather, install it to the /boot partition (on my test system this was /dev/sda3). Finish the installation. It won't yet be bootable. Now, boot your liveUSB stick. When you get your desktop, pull up a terminal and become root. At the root prompt, invoke gdisk just like you would fdisk, making sure to get the right disk device and partition. The command set for gdisk is virtually identical to fdisk. Use 'p' to list the partitions; you'll see your /boot as a partition type of 'EF00' as set by parted in the installer. You want to change that partition type to '0700' instead. The bootable partition must remain the small EFI boot partition of type EF00. You can name the partitions with the 'c' command; I encourage this. Use the 'w' to write out the GPT when done, and shut down. Remove the CentOS 6 liveUSB and reboot. Chameleon should automatically pick up the 'Linux' system in its bootsplash. Now, it may be possible to get parted to make the /boot partition to be type 0700 instead of EF00; didn't try that, since I know gdisk will do it correctly. As I was using a Dell Inspiron 640m, I used a Chameleon boot CD for a Dell Latitude D620 to good effect; you can find that on insanelymac.com. That particular Chameleon install includes a Dell logo and such, and may be some different from your particular Chameleon install. I have not tried this with a drive larger than 2TB; google for 'Chameleon bootloader EFI 2TB' to see the progress in this area. In theory this would allow a BIOS booting machine to boot directly on a 2TB+ drive using GPT without having EFI or variant in the BIOS. Once I get a single drive large than 2TB, or free up a machine with an FC connection and a > 2TB LUN attached to it, I'll try that out, and attempt to do a Chameleon installation without the OSX step in between. -- Lamar Owen Chief Information Officer Pisgah Astronomical Research Institute 1 PARI Drive Rosman, NC 28772 http://www.pari.edu

ldirectord package on centos 6
by Dennis Jacobfeuerborn 16 May '12

16 May '12

Hi, I'm looking for the ldirectord package but can't find it. Previously this was available as "heartbeat-ldirectord" and nowadays it is built as an independent package from "resource-agents" however neither seems to be available either in core centos 6 or epel. Where did it go? Regards, Dennis

OSS DSP sound card input on CentOS 6.2?
by Gilbert Sebenste 16 May '12

16 May '12

Hello everyone, I'm streaming audio on CentOS 5.8 with no problem, even on a cheap sound card using DarkIce as the input tool. For the input under CentOS5, I use: device = /dev/dsp # OSS DSP soundcard device for the audio input But under CentOS 6.2, there is no such device. I see /dev/snd, and it has: controlC0 hwC0D2 midiC0D1 pcmC0D0p pcmC0D2p pcmC1D0p seq controlC1 hwC1D0 midiC0D2 pcmC0D1c pcmC0D3p pcmC1D1p timer hwC0D0 midiC0D0 pcmC0D0c pcmC0D2c pcmC1D0c pcmC1D2c But nothing that looks OSS-ish to me. Any ideas as to what I need to point at, and why? Any help is greatly appreciated. Thanks!

cpuspeed causing high load average?
by tony＠softins.co.uk 16 May '12

16 May '12

On a new server's CentOS5 install, with nothing in the way of applications running yet, I noticed that the load average was sitting between 2 and 5 all the time, even though top told me CPU was 100% idle. Eventually I found that stopping the "cpuspeed" subsystem allowed the load average to drop down to near zero, as I would expect it to be. I have the default /etc/sysconfig/cpuspeed with no customizations. Is the above behaviour expected? It seems wrong to me. Is cpuspeed broken? I did notice that with cpuspeed running, the CPUs were running at their minimum frequency of 1.6GHz, and after stopping the cpuspeed service they went up to their maximum speed of 2.8GHz. The system has a pair of E5660 Xeons, which Linux reports as 24 CPUs!

Sendmail problem - baffled
by Jussi Hirvi 16 May '12

16 May '12

Our backup mail server (which I have just re-configured) tries to contact the primary mail server, and fails. My log shows repeatedly "connection refused": May 15 22:21:41 mx2 sm-mta-rx[8674]: q4FIhPij007483: makeconnection (mail.greenspot.fi.

[83.143.217.182], dsn=4.0.0, stat=Deferred: Connection refused by mail.greenspot.fi. But yet I can successfully telnet that host: # telnet mail.greenspot.fi 25 Trying 83.143.217.182...

Escape character is '^]'. 220 mail.greenspot.fi ESMTP Sendmail; Tue, 15 May 2012 22:34:22 +0300 Also, the mailer-daemon *can* send automatic warning messages to mail.greenspot.fi just fine. So, the error probably is in my sendmail configuration. The error appeared as I today reconfigured the backup mail server to use a "dual sendmail" setup with amavis and greylisting. How could I proceed? - Jussi

True bond howto for Centos 6
by aurfalien 15 May '12

15 May '12

Hi all, Read many posts on the subject. Using 802.3ad. Few problems; Cannot ping some hosts on the network, they are all up. Cannot resolve via DNS which is one of the hosts that I cannot ping, internal nor external DNS hosts. Unplugging the NICS and plugging them back in will then not allow pining if the default d=gateway. When cold booting it somewhat works, some hosts are pingable while others are not. When restarting the network service via /etc/init.d/network, nothing is pingable. Here are my configs; ifcfg-bond0 DEVICE=bond0 USERCTL=no BOOTPROTO=none ONBOOT=yes IPADDR=10.0.0.10 NETMASK=255.255.0.0 NETWORK=10.0.0.0 TYPE=Unknown IPV6INIT=no ifcfg-eth0 DEVICE=eth0 BOOTPROTO=none ONBOOT=yes MASTER=bond0 SLAVE=yes USERCTL=no ifcfg-eth1 DEVICE=eth1 BOOTPROTO=none ONBOOT=yes MASTER=bond0 SLAVE=yes USERCTL=no /etc/modprob.d/bonding.conf alias bond0 bonding options bond0 mode=5 miimon=100 Bonding worked great in Centos 5.x, not so well for me in Centos 6.2. My goal is to get this working under bridging for KVM, I can only imagine the nightmare seeing I can't get a simple bond to work! Any guidance is golden. - aurf

Excluding ConsoleKit in kickstart
by Dennis Jacobfeuerborn 15 May '12

15 May '12

Hi, I'm working on automating virtual machine installs using kickstart files and virt-install. The problem I have is that these kickstart installations install different packages than a minimal manual install. While I got rid of some of them I can't seem to prevent ConsoleKit from getting installed. I put "-ConsoleKit" in the packages section and later also added packages that require it but in the end it is still getting installed. Any ideas what I could do to stop it from being installed? Regards, Dennis
